A randomized phase II feasibility trial of a multimodal intervention for the management of cachexia in lung and pancreatic cancer

Analysis of postoperative weight loss associated with prognosis after sublobar resections for lung cancer

OBJECTIVES

Sublobar resections for lung cancer are increasing worldwide. However, the prognostic significance of weight loss after sublobar resection remains unclear. We aimed to investigate the prognostic significance of weight loss after sublobar resection for lung cancer.

METHODS

Patients who underwent sublobar resection for non-small cell lung cancer between January 2016 and June 2021 were analysed. The percentage weight change at 3, 6, and 12 months postoperatively was determined based on the preoperative weight. Patients were divided into two groups: those with or without weight loss ≥ 5%, referring to the diagnostic criteria for frailty, to assess prognosis. Subsequently, the prognosis-related timing of weight loss ≥ 5% and its risk factors were analyzed.

RESULTS

We reviewed 147 patients; 39 (26.5%) showed weight loss ≥ 5% within 1-year post-surgery. A total of 32 patients (21.8%) died, 13 from primary lung cancer and 19 from non-lung cancer causes. Cancer recurrence occurred in 22 patients (15.0%). Weight loss ≥ 5% within 1-year post-surgery was a poor prognostic factor for overall and recurrence-free survival (log-rank; p = 0.014 and 0.018, respectively). Additionally, weight loss ≥ 5% at 6-12 months postoperatively was associated with poor overall and recurrence-free survival (p < 0.05, both). In the multivariable analysis, an age-adjusted Charlson comorbidity index ≥ 4 was a predictive factor for weight loss ≥ 5% at 6-12 months postoperatively (odds ratio, 3.920; p = 0.023).

CONCLUSIONS

Weight loss ≥ 5% at 6-12 months postoperatively was associated with poor prognosis. Long-term nutritional management is important in the treatment plan of sublobar resection in high-risk patients.

The relationship between tumour necrosis, systemic inflammation, body composition and survival in patients with colon cancer

BACKGROUND

In cancer cachexia the relationship between the tumour, its environment and the systemic inflammatory response is not clear. This study aims to examine this relationship in greater detail.

METHODS

Host characteristics included the presence of a Systemic Inflammatory Response (SIR) as measured by Systemic Inflammatory Grade (SIG), sarcopenia (SMI) and myosteatosis (SMD) were measured. Categorical variables were analysed using χ2 test for linear-by-linear association, or χ2 test for 2 by 2 tables. Survival analysis was carried out using univariate and multivariate Cox regression.

RESULTS

A total of 473 patients were included. Of these, 70.4% were over 65 years of age, 54.8% were male and 49.8% had an ASA grade of 1 or 2. Pathological examination showed that the majority of patients had a T3 (53.7%) or a T4 (34.0%) cancer and 73.0% had evidence of necrosis. A SIG score of 0 or 1 was present in 57.7% of patients. Tumour necrosis was associated with age (p < 0.01), tumour location (p < 0.01), T-stage (p < 0.001), margin involvement (p < 0.05), SIG (p < 0.001), SMI (p < 0.01), SMD (p < 0.05) and 5-year survival (p < 0.001). On multivariate survival analysis in patients with T3 cancers age (HR: 1.45 95% CI 1.13-1.86 p < 0.01), ASA grade (HR: 1.50 95% CI 1.15-1.95 p < 0.01) and SIG (HR: 1.28 95% CI 1.11-1.48 p < 0.001) remained independently associated with survival.

CONCLUSION

These results suggest that tumour necrosis and the subsequent SIR could result in profound changes in body composition and survival. Further pre-clinical and clinical work is required to prove causation.

Muscle Loss During First-Line Chemotherapy Impairs Survival in Advanced Pancreatic Cancer Despite Adapted Physical Activity

BACKGROUND

Advanced pancreatic ductal adenocarcinoma (aPDAC) is often accompanied by significant muscle mass loss, contributing to poor prognosis. SarcAPACaP, an ancillary study of the GERCOR-APACaP phase III trial, evaluated the role of adapted physical activity (APA) in aPDAC Western patients receiving first-line chemotherapy. The study aimed to assess (1) the potential impact of computed tomography (CT)-quantified muscle mass before and during treatments on health-related quality of life (HRQoL) and overall survival (OS) and (2) the role of APA in mitigating muscle mass loss.

METHODS

In the APACaP trial, aPDAC patients with ECOG performance status (PS) 0-2 were randomized 1:1 to usual care including first-line chemotherapy or usual care plus a 16-week home-based APA program. In the SarcAPACaP study, the surface muscular index (SMI) was determined from L3 CT scan slices. Two patient populations were analysed: those with CT scan available at baseline (modified[m] intent-to-treat [ITT]1-W0) and those with CT scans available at both W0 and W16 (mITT2 W0-W16). Low muscle mass was defined by low SMI with SMI < 41 cm2/m2 for women and < 43 and < 53 cm2/m2 for men with body max index < 25.0 and ≥ 25.0 kg/m2, respectively. Muscle loss was defined by the relative difference of SMI between W0 and W16 (100*[SMI W16-SMI W0]/SMI W0). In mITT2 W0-W16, patients were stratified into three groups based on the severity of muscle loss: none, moderate (0%-10%) and high (≥ 10%). Associations between muscle mass loss and OS, time until definitive deterioration (TUDD) of HRQoL and the effect of APA on loss of muscle mass were assessed.

RESULTS

Between October 2014 and May 2020, 313 patients were prospectively enrolled, with 225 in mITT1 W0 and 128 in mITT2 W0-W16, with 65 assigned to the APA arm. Both groups had similar baseline characteristics with comparable OS and TUDD. A low SMI at W0 was not associated with OS and TUDD of HRQoL in either group. Among mITT2 W0-W16 patients, high muscle mass loss (n = 27) independently predicted OS (p = 0.012) and showed a trend toward negatively affecting TUDD of HRQoL. Notably, APA did not mitigate muscle loss in our study population.

CONCLUSIONS

Longitudinal muscle mass loss emerged as a predictive factor for both OS and HRQoL in aPDAC patients undergoing chemotherapy, while a low SMI at diagnosis did not provide prognostic value. APA did not impact muscle mass loss in this population.

Adherence to Oral Nutritional Supplements: A Review of Trends in Intervention Characteristics and Terminology Use Since the Year 2000

Research on disease-related malnutrition and adherence to oral nutritional supplements (ONS) has increased in recent years. To guide future studies, it is important to identify trends in terminology use and intervention characteristics. This review aimed to map characteristics of research investigating adherence to ONS in patients with disease-related malnutrition and explore changes over time. This review is a secondary analysis of quantitative studies from a systematic mixed-studies review. Online databases, including PubMed, Cinahl, Cochrane Central Register of Controlled Trials, and APA PsycInfo, were searched to identify studies published from 2000 to March 2022. A quantitative content analysis of extracted data was performed, and the Mixed Methods Appraisal Tool (MMAT) was used to assess methodological risk of bias. This review includes 137 articles, over half of which are randomized controlled trials (52%). The term "oral nutritional supplements" was used in 40% of the studies. Adherence to ONS was mainly described by the term "compliance" (69%). It was most common to offer ready-made milk-based ONS (56%) and ONS as a sole intervention (51%). The prescribed dose of ONS was fixed in 64% of studies and individualized in 22% of studies. There was variation in the methods used to assess adherence to ONS, and adherence was not reported in nearly a fifth of studies. There was an increase in methodological quality over time (p = 0.024). To ensure better understanding and increase the rigor and reproducibility of ONS intervention research, it is crucial to standardize the terminology used and to describe the interventions clearly.

Nutritional interventions in randomised clinical trials for people with incurable solid cancer: A systematic review

BACKGROUND & AIMS

Malnutrition is highly prevalent in those with cancer and more so in those with incurable cancer. In incurable cancer, it is widely agreed that optimal nutritional care has the potential to positively impact patient and caregiver distress and oncological outcomes. The aim of this systematic review was to describe the diversity and frequency of nutritional interventions, whether given in isolation or as part of a multimodal intervention in those with incurable cancer, in randomised controlled trials. The secondary aims were to describe adherence and their efficacy.

METHODS

This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. The following databases were searched electronically: Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica database (EMBASE), Cumulated Index to Nursing and Allied Health Literature (CINAHL) and Cochrane Central Register of Controlled Trials (CENTRAL) with the time frame from January 2000 to 7th September 2023. Eligible studies included adult patients (≥18 years) diagnosed with incurable solid cancer with a sample size ≥40. Studies were to be primary research and delivered for at least 14 days to allow for efficacy. They were to include a nutritional intervention encompassing at least one of the following: dietary counselling, oral nutritional supplements (ONS), enteral tube feeding and/or parenteral nutrition (PN), given in isolation or as part of a multi-modal intervention. Studies were excluded if the population contained patients who had completed curative treatment or are being treated with curative intent, haematological cancers, or if they examined the effects of micronutrients, proteins, amino acids or fatty acids given in isolation. The quality of the included studies was assessed using the Cochrane risk of bias tool for randomised trials (RoB2). A balloon plot was produced to present the results in addition to a table with a narrative summary of the primary outcomes.

RESULTS

A total of 7968 studies were identified, of which 18 met the eligibility criteria. This included 2720 study participants. The included studies comprised: multimodal interventions (n = 7), dietary counselling (n = 2), nutritional supplementation with or without dietary counselling (n = 7) and PN (n = 2). Primary outcomes included quality of life (QoL), body composition and nutritional status. For QoL, this was reported in 15 studies, 4 studies showed a significant improvement. Body composition was evaluated in 15 studies, 5 of which showed a significant improvement in body weight and two in fat-free mass (FFM). Nutritional status was reported in 6 studies with one showing a significant difference in Patient-Generated Subjective Global Assessment (PG-SGA) score. The risk of bias was deemed 'low' in 6 studies, with 'some concerns' in 10 studies and a 'high risk' in 2 studies. There was heterogeneity between the studies.

CONCLUSION

This systematic review has highlighted some positive findings in regard to QoL, body weight and nutritional intake. Optimum nutritional intervention was not identified. Future studies should evaluate the effectiveness of earlier nutritional interventions at the point of diagnosis, including regular reviews and the impact this has on nutritional outcomes, QoL and overall survival (OS).

Definition and assessment of adherence to oral nutritional supplements in patients with neoplasms: a scoping review

INTRODUCTION

Cancer remains a leading cause of death globally, with patients frequently experiencing malnutrition due to both the disease and its treatment, which negatively affects their quality of life and treatment outcomes. Oral nutritional supplements (ONS) provide a noninvasive solution to improve nutritional status, but poor patient adherence limits their effectiveness. Studies on ONS adherence vary in their definitions and assessment tools, creating inconsistencies. A scoping review is essential to synthesize these studies and establish a foundation for future research and clinical practice.

METHOD

We systematically searched six databases, including Web of Science, PubMed, and Scopus, up to August 2024. Our criteria focused on oncology patients, ONS interventions, and outcomes related to adherence definitions, assessment methods, and adherence rates.

RESULTS

37 studies from 2005 to 2024 met the inclusion criteria. Definitions of ONS adherence and assessment methods vary widely, with the most common definition being the ratio of actual intake to the recommended amount. The assessment tools included self-reported ONS diaries, and MMAS scores, among others. Adherence rates also vary significantly, with some studies reporting a decline in adherence over time.

CONCLUSION

The lack of standardized definitions and assessment methods for ONS adherence across studies hinders comparability. Future research should focus on developing standardized, comprehensive adherence assessment tools that incorporate both quantitative and qualitative data. This would allow for a better understanding of adherence factors and enable more targeted interventions to improve long-term adherence in cancer patients.

Potential Benefits from Physical Exercise in Advanced Cancer Patients Undergoing Systemic Therapy? A Narrative Review of the Randomized Clinical Trials

DESIGN

The purpose of this review is the analysis of the literature concerning the effects of physical exercise in cancer patients undergoing medical oncologic treatment. Papers were retrieved from the scrutiny of 15 reviews/meta-analyses published in the last 2 years, which, however, pooled different populations of patients (surgical and medical patients, receiving or not an oncologic therapy, harboring a cancer, or being survivors).

RESULTS

We reviewed the data of 35 RCTs on the use of physical exercise in cancer patients, distinguishing well-nourished from malnourished patients. The conclusions of our study are the following: No major difference between well-nourished and malnourished patients as regards compliance/adherence with physical exercise and outcomes. Compliance with physical exercise was reported in about 70% of the studies. Compared with a control group receiving the usual care, in patients who practiced physical exercise, a benefit in some parameters of physical function and quality of life and lean body mass (LBM) was reported in 61%, 47%, and 12%, respectively, of the studies in non-malnourished patients, and in 50%, 100%, and 36%, respectively, of the studies in malnourished patients. The benefit in LBM was more frequently reported in weight-losing patients. There was no strict association among the results of different outcomes (muscle function vs. quality of life vs. LBM). There are still some ill-defined issues, including the optimal physical regimen (with some authors favoring high-intensity interval training and resistance) and the place of exercising (patients usually preferring home exercises, which, however, have been proved less efficacious).

Development of a Leg And Walking Self-exercise (LAWS) program for older adults during cancer treatment

PURPOSE

We developed a self-directed Leg And Walking Self-exercise (LAWS) program informed by the Exercise is Medicine initiative and evaluated the feasibility and acceptability of this program in older adults with cancer.

METHODS

Over a 1-year period, we prospectively enrolled 40 older adults who received a comprehensive geriatric assessment (CGA) at a geriatric oncology service and initiated a new line of systemic therapy for advanced cancer as inpatients. LAWS is a tailored, self-directed exercise program consisting of leg resistance training and walking. Exercise adherence was recorded using an exercise diary to assess feasibility. Patient perspectives on this program were evaluated using the Feasibility of Intervention Measure (FIM) and Acceptability of Intervention Measure (AIM), with a score range of 1-5, higher being better.

RESULTS

Overall, 28% of patients were fit, 53% pre-frail, and 20% frail based on the CGA. During hospitalization (average 12 days), 63% of the patients adhered to exercises at lowest intensity during more than 50% of their inpatient stay: on average, 2.8 leg exercises, 23 repetitions a day, 5.6 days/week, and 19 min of walking a day, 4.9 days/week. Patients rated their perceived exertion at 3.0 for leg exercise and 3.0 for walking on a 1-10 Likert scale. During the period between discharge and their first outpatient appointment (average 11 days), 71% of patients adhered to the LAWS program. Mean scores of FIM and AIM were 4.2 (SD = 0.5) and 4.2 (SD = 0.7), respectively.

CONCLUSIONS

For older adults undergoing cancer treatment, LAWS is a feasible and acceptable self-directed exercise program.

Understanding the complexity of barriers and facilitators to adherence to oral nutritional supplements among patients with malnutrition: a systematic mixed-studies review

The aim of this systematic mixed-studies review is to summarise barriers/facilitators to adherence to and/or consumption of oral nutritional supplements (ONS) among patients with disease-related malnutrition. In March 2022, the Cochrane CENTRAL, PUBMED, PsycINFO (Ovid) and CINAHL were searched for articles with various study designs, published since 2000. Articles were identified on the basis of 'population' (patients ≥18 years with malnutrition/at nutritional risk), 'intervention' (ONS with ≥2 macronutrients and micronutrients), 'comparison' (any comparator/no comparator) and 'outcome' (factors affecting adherence or consumption) criteria. A sequential exploratory synthesis was conducted: first, a thematic synthesis was performed identifying barriers/facilitators; and second, the randomised controlled trials (RCTs) were used to support these findings. The five WHO dimensions of adherence guided the analysis. Study inclusion, data extraction, analysis and risk-of-bias assessment (MMAT 2018) were carried out independently by two researchers. From 21 835 screened articles, 171 were included with 42% RCTs and 20% qualitative studies. The two major populations were patients with malignancies (34%) and older adults (35%). In total, fifty-nine barriers/facilitators were identified. Patients' health status, motivation, product tolerance and satisfaction as well as well-functioning healthcare routines and support were factors impacting ONS consumption. Few barriers/facilitators (n = 13) were investigated in RCTs. Two of those were serving a small ONS volume and integrating ONS into ward routines. Given the complexity of ONS adherence, non-adherence to ONS should be addressed using a holistic approach. More studies are needed to investigate the effect of different approaches to increase adherence to ONS.

A rapid review of nutrition and exercise approaches to managing unintentional weight loss, muscle loss, and malnutrition in cancer

PURPOSE

This narrative review summarizes the evidence for nutrition, exercise, and multimodal interventions to maintain weight and muscle mass and prevent malnutrition from meta-analysis, systematic reviews, and randomized controlled trials published within the last 5 years, and in comparison to future research priority areas identified by international guidelines.

RECENT FINDINGS

Dietary counseling with oral nutrition support (ONS), escalated to enteral nutrition if weight loss continues, is the gold standard treatment approach to maintaining weight and preventing malnutrition. Recent ONS trials with dietary counseling show promising findings for weight maintenance, extending the literature to include studies in chemoradiotherapy, however, change in body composition is rarely evaluated. Emerging trials have evaluated the impact of isolated nutrients, amino acids, and their derivatives (ie, β-hydroxy β-methylbutyrate) on muscle mass albeit with mixed effects. There is insufficient evidence evaluating the effect of exercise interventions on unintentional weight loss, muscle mass, and malnutrition, however, our knowledge of the impact of multimodal nutrition and exercise interventions is advancing. Prehabilitation interventions may attenuate weight and muscle loss after surgery, particularly for patients having gastrointestinal and colorectal surgery. Multimodal trials that commence during treatment show mixed effects on weight and muscle mass when measured.

SUMMARY

This review highlights that the evidence for preventing unintentional weight loss and malnutrition from cancer treatment is strong within nutrition. Multimodal interventions are emerging as effective interventions to prevent unintentional weight loss. Promising interventions are demonstrating improvements in muscle mass, however further exploration through studies designed to determine the effect on muscle is required.

Comparison between AWGC-cachexia and GLIM-malnutrition in patients with gastric cancer

BACKGROUND

The newly released Asian Working Group for Cachexia (AWGC) criteria share similar diagnostic items with the Global Leadership Initiative on Malnutrition (GLIM) criteria. This study aims to compare the AWGC cachexia and GLIM malnutrition in patients with gastric cancer and investigate whether one diagnosis continues to be a prognostic factor in individuals diagnosed with the other condition.

METHODS

Data of patients who underwent radical gastrectomy for gastric adenocarcinoma were prospectively collected from 2013 to 2019. The AWGC and GLIM criteria were applied to diagnosis cachexia and malnutrition, respectively. Univariate and multivariate logistic and Cox regression were used to verify the effect of relevant factors on postoperative complications and overall survival.

RESULTS

A total of 1420 patients were included, among whom 174 (12.3 %) were diagnosed with AWGC-cachexia alone, 85 (6.0 %) were diagnosed with GLIM-malnutrition alone, and 324 (22.8 %) had both AWGC-cachexia and GLIM-malnutrition. Both AWGC-cachexia and GLIM-malnutrition were independent risk factors for complications and overall survival. When they coexisted, the odds ratios (OR) and hazard ratios (HR) tended to be higher. In the AWGC-cachexia subset, GLIM-malnutrition remained an independent risk factor (HR = 1.544, 95 % CI = 1.098-2.171, P = 0.012) for overall survival after the adjustment of confounding factors. Similarly, in the GLIM-malnutrition subset, AWGC-cachexia remained an independent risk factor for overall survival (HR = 1.697, 95 % CI = 1.087-2.650, P = 0.020). Patients with both cachexia and malnutrition had the worst overall survival.

CONCLUSION

AWGC-cachexia and GLIM-malnutrition criteria were two non-redundancy tools in reflecting mortality risk in preoperative nutritional assessment.

Molecular mechanisms of cancer cachexia. Role of exercise training

Cancer-associated cachexia represents a multifactorial syndrome mainly characterized by muscle mass loss, which causes both a decrease in quality of life and anti-cancer therapy failure, among other consequences. The definition and diagnostic criteria of cachexia have changed and improved over time, including three different stages (pre-cachexia, cachexia, and refractory cachexia) and objective diagnostic markers. This metabolic wasting syndrome is characterized by a negative protein balance, and anti-cancer drugs like chemotherapy or immunotherapy exacerbate it through relatively unknown mechanisms. Due to its complexity, cachexia management involves a multidisciplinary strategy including not only nutritional and pharmacological interventions. Physical exercise has been proposed as a strategy to counteract the effects of cachexia on skeletal muscle, as it influences the mechanisms involved in the disease such as protein turnover, inflammation, oxidative stress, and mitochondrial dysfunction. This review will summarize the experimental and clinical evidence of the impact of physical exercise on cancer-associated cachexia.

Effect of Combined Exercise and Nutrition Interventions During Inpatient Chemotherapy in Acute Leukemia and Malignant Lymphoma Patients: A Randomized Controlled Trial

The aim of the present study was to determine the effectiveness of combined exercise and nutrition interventions on physical function and quality of life (QOL) in patients with acute leukemia or malignant lymphoma (ML) during inpatient chemotherapy. The study was a randomized controlled trial where patients with acute leukemia or ML who were receiving inpatient chemotherapy and exercise therapy were divided into an intervention group (IG) and a control group (CG). Both groups underwent resistance training and aerobic exercise. The patients in the IG were instructed to take nutritional supplements twice a day. Assessment items were muscle strength (handgrip strength and knee extension strength), 6-min walking test, skeletal muscle mass, QOL, nutritional status, and fatigue. Two-way analysis of variance showed a significant interaction for bilateral handgrip strength and knee extension strength. No significant interactions were found for the other items. The results of the present study showed improved muscle strength in the IG compared to the CG, indicating the effectiveness of combined exercise and nutrition interventions during inpatient chemotherapy in patients with acute leukemia or ML.

Impact of exercise on cancer: mechanistic perspectives and new insights

This review critically evaluates the substantial role of exercise in enhancing cancer prevention, treatment, and patient quality of life. It conclusively demonstrates that regular physical activity not only reduces cancer risk but also significantly mitigates side effects of cancer therapies. The key findings include notable improvements in fatigue management, reduction of cachexia symptoms, and enhancement of cognitive functions. Importantly, the review elucidates the profound impact of exercise on tumor behavior, modulation of immune responses, and optimization of metabolic pathways, advocating for the integration of exercise into standard oncological care protocols. This refined abstract encourages further exploration and application of exercise as a pivotal element of cancer management.

Anamorelin for the Treatment of Cancer Anorexia-Cachexia Syndrome

PURPOSE OF REVIEW

The following review will highlight the development of anamorelin to treat cancer anorexia-cachexia syndrome (CACS) including the potential benefits, limitations, and future directions.

RECENT FINDINGS

Ghrelin, a 28-amino acid peptide hormone, is secreted by the stomach mucosa and regulates appetite, promotes lipogenesis, increases body weight, improves gastric motility, reduces catabolic wasting and inflammation. Several randomized, double-blind, placebo-controlled clinical trials evaluating anamorelin, a ghrelin agonist, for the treatment of CACS have reported improvement in appetite and body composition including both lean body and fat mass; however, most studies noted no improvement in physical function as assessed by measuring non-dominant hand-grip strength. Common adverse effects of anamorelin include the development of diabetes mellitus, hyperglycemia, and less frequently, hepatic abnormalities and cardiovascular events including conduction abnormalities, hypertension, and ischemic cardiomyopathy. Anamorelin has the potential to stimulate appetite, improve gastric movement, and may have anti-inflammatory effects on patients with CACS. In patients with cancer, studies involving anamorelin combined with other multimodal treatments including nutrition counseling (branched chain amino acids, omega 3 fatty acids, and other nutrients), exercise, treatment of hormonal abnormalities including hypogonadism and hypovitaminosis D, and anti-inflammatory agents are needed. Compliance with multimodality treatment has been a barrier and future studies may need to incorporate motivational counseling to promote adherence.

Nutritional Status Is Associated With Physical Improvement of Palliative Cancer Patients During Cancer Rehabilitation

Background/Aim

Physical decline is accompanied with malnutrition in advanced cancer patients, thus nutritional care is often provided with cancer rehabilitation. However, a limited number of studies have focused on which nutritional index serves as an important marker to provide more intensive nutritional support for patients.

Patients and Methods

We retrospectively reviewed advanced cancer patients who received chemotherapy and rehabilitation during hospitalization. In analysis 1, patients were divided into two groups: a Well group with caloric intake ≥ basal metabolism, calculated by the Harris-Benedict equation, and a Poor group with caloric intake less than their basal energy expenditure. The primary endpoint was the ratio of patients whose Eastern Cooperative Oncology Group Performance Status (ECOG PS) or Barthel index (BI) was maintained during rehabilitation. In analysis 2, the cohort was restratified into Responders, whose ECOG PS and BI improved, and Non-responders, comprising the remaining patients. Several nutritional indices were compared between the groups.

Results

Eighty-four patients were evaluated in analysis 1, namely 51 Well patients and 33 Poor patients. The ECOG PS-maintained rate was 98% and 91% (p=0.29), and the BI-maintained rate was 100% and 88% (p=0.02) in the Well and Poor groups, respectively. In analysis 2, 72 patients were evaluated after excluding 12 patients who lacked nutritional data after rehabilitation. Compared with the Responders group, caloric intake appeared worse in the Non-responders group, although their nutritional background tended to be better.

Conclusion

Insufficient caloric intake might be a predictive marker of poor outcomes after rehabilitation in advanced cancer patients.

Feasibility of two levels of protein intake in patients with colorectal cancer: findings from the Protein Recommendation to Increase Muscle (PRIMe) randomized controlled pilot trial

BACKGROUND

Low muscle mass (MM) predicts unfavorable outcomes in cancer. Protein intake supports muscle health, but oncologic recommendations are not well characterized. The objectives of this study were to evaluate the feasibility of dietary change to attain 1.0 or 2.0 g/kg/day protein diets, and the preliminary potential to halt MM loss and functional decline in patients starting chemotherapy for stage II-IV colorectal cancer.

PATIENTS AND METHODS

Patients were randomized to the diets and provided individualized counseling. Assessments at baseline, 6 weeks, and 12 weeks included weighed 3-day food records, appendicular lean soft tissue index (ALSTI) by dual-energy X-ray absorptiometry to estimate MM, and physical function by the Short Physical Performance Battery (SPPB) test.

RESULTS

Fifty patients (mean ± standard deviation: age, 57 ± 11 years; body mass index, 27.3 ± 5.6 kg/m2; and protein intake, 1.1 ± 0.4 g/kg/day) were included at baseline. At week 12, protein intake reached 1.6 g/kg/day in the 2.0 g/kg/day group and 1.2 g/kg/day in the 1.0 g/kg/day group (P = 0.012), resulting in a group difference of 0.4 g/kg/day rather than 1.0 g/kg/day. Over one-half (59%) of patients in the 2.0 g/kg/day group maintained or gained MM compared with 44% of patients in the 1.0 g/kg/day group (P = 0.523). Percent change in ALSTI did not differ between groups [2.0 g/kg/day group (mean ± standard deviation): 0.5% ± 4.6%; 1.0 g/kg/day group: -0.4% ± 6.1%; P = 0.619]. No differences in physical function were observed between groups. However, actual protein intake and SPPB were positively associated (β = 0.37; 95% confidence interval 0.08-0.67; P = 0.014).

CONCLUSION

Individualized nutrition counselling positively impacted protein intake. However, 2.0 g/kg/day was not attainable using our approach in this population, and group contamination occurred. Increased protein intake suggested positive effects on MM and physical function, highlighting the potential for nutrition to attenuate MM loss in patients with cancer. Nonetheless, muscle anabolism to any degree is clinically significant and beneficial to patients. Larger trials should explore the statistical significance and clinical relevance of protein interventions.

P-move: a randomized control trial of exercise in patients with advanced pancreatic or biliary tract cancer (aPBC) receiving beyond first-line chemotherapy

PURPOSE

Patients with advanced pancreatic and biliary tract cancer (aPBC) frequently suffer from high symptom burden. Exercise can reduce treatment side effects and improve patient-related outcomes (PROMs). However, evidence from prospective studies regarding feasibility and efficacy in advanced settings are sparse. The primary aim of this prospective, randomized-controlled study was to evaluate the feasibility and effects of exercise (ET) in patients with aPBC.

METHODS

Patients with aPBC beyond first-line therapy were randomized according to the minimization procedure with stratification by gender, age, and loss of body weight in the past six months. The intervention group (IG) completed 3 training units/week for 8 weeks (1x supervised strength sessions, 2x individualized home-based sessions). Control group (CG) received recommendations on physical activity during cancer.

RESULTS

41 patients (stage IV pancreatic or biliary tract cancer) were included no adverse events related to exercise occurred during the trial. Physical function increased significantly in IG in 5 out of 7 physical domains. Comparison of IG and CG at 8 weeks (t2) showed significant differences in favour of IG in leg press (p=0.001), bench press (p=0.011), sit-to-stand (p=0.001) and crunch (0.006). Constipation revealed a significant difference in favour of IG at t2 (p=0.033). Quality of life stabilized/increased in IG during the study period compared to a decrease in CG. Throughout/Over the 8 weeks, fatigue notably reduced in the IG (p=0.028).

CONCLUSION

Exercise is safe and feasible in patients with aPBC undergoing further line therapy. Significant improvements in physical functioning and increased quality of life were achieved. German Clinical Trials Register ID: DRKS00021179; Registration date 15.05.2020.

Biomarker endpoints in cancer cachexia clinical trials: Systematic Review 5 of the cachexia endpoint series

Regulatory agencies require evidence that endpoints correlate with clinical benefit before they can be used to approve drugs. Biomarkers are often considered surrogate endpoints. In cancer cachexia trials, the measurement of biomarkers features frequently. The aim of this systematic review was to assess the frequency and diversity of biomarker endpoints in cancer cachexia trials. A comprehensive electronic literature search of MEDLINE, Embase and Cochrane (1990-2023) was completed. Eligible trials met the following criteria: adults (≥18 years), prospective design, more than 40 participants, use of a cachexia intervention for more than 14 days and use of a biomarker(s) as an endpoint. Biomarkers were defined as any objective measure that was assayed from a body fluid, including scoring systems based on these assays. Routine haematology and biochemistry to monitor intervention toxicity were not considered. Data extraction was performed using Covidence, and reporting followed PRISMA guidance (PROSPERO: CRD42022276710). A total of 5975 studies were assessed, of which 52 trials (total participants = 6522) included biomarkers as endpoints. Most studies (n = 29, 55.7%) included a variety of cancer types. Pharmacological interventions (n = 27, 51.9%) were most evaluated, followed by nutritional interventions (n = 20, 38.4%). Ninety-nine different biomarkers were used across the trials, and of these, 96 were assayed from blood. Albumin (n = 29, 55.8%) was assessed most often, followed by C-reactive protein (n = 22, 42.3%), interleukin-6 (n = 16, 30.8%) and tumour necrosis factor-α (n = 14, 26.9%), the latter being the only biomarker that was used to guide sample size calculations. Biomarkers were explicitly listed as a primary outcome in six trials. In total, 12 biomarkers (12.1% of 99) were used in six trials or more. Insulin-like growth factor binding protein 3 (IGFBP-3) and insulin-like growth factor 1 (IGF-1) levels both increased significantly in all three trials in which they were both used. This corresponded with a primary outcome, lean body mass, and was related to the pharmacological mechanism. Biomarkers were predominately used as exploratory rather than primary endpoints. The most commonly used biomarker, albumin, was limited by its lack of responsiveness to nutritional intervention. For a biomarker to be responsive to change, it must be related to the mechanism of action of the intervention and/or the underlying cachexia process that is modified by the intervention, as seen with IGFBP-3, IGF-1 and anamorelin. To reach regulatory approval as an endpoint, the relationship between the biomarker and clinical benefit must be clarified.

Body weight and composition endpoints in cancer cachexia clinical trials: Systematic Review 4 of the cachexia endpoints series

Significant variation exists in the outcomes used in cancer cachexia trials, including measures of body composition, which are often selected as primary or secondary endpoints. To date, there has been no review of the most commonly selected measures or their potential sensitivity to detect changes resulting from the interventions being examined. The aim of this systematic review is to assess the frequency and diversity of body composition measures that have been used in cancer cachexia trials. MEDLINE, Embase and Cochrane Library databases were systematically searched between January 1990 and June 2021. Eligible trials examined adults (≥18 years) who had received an intervention aiming to treat or attenuate the effects of cancer cachexia for >14 days. Trials were also of a prospective controlled design and included body weight or at least one anthropometric, bioelectrical or radiological endpoint pertaining to body composition, irrespective of the modality of intervention (e.g., pharmacological, nutritional, physical exercise and behavioural) or comparator. Trials with a sample size of <40 patients were excluded. Data extraction used Covidence software, and reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance. This review was prospectively registered (PROSPERO: CRD42022276710). A total of 84 clinical trials, comprising 13 016 patients, were eligible for inclusion. Non-small-cell lung cancer and pancreatic cancer were studied most frequently. The majority of trial interventions were pharmacological (52%) or nutritional (34%) in nature. The most frequently reported endpoints were assessments of body weight (68 trials, n = 11 561) followed by bioimpedance analysis (BIA)-based estimates (23 trials, n = 3140). Sixteen trials (n = 3052) included dual-energy X-ray absorptiometry (DEXA)-based endpoints, and computed tomography (CT) body composition was included in eight trials (n = 841). Discrepancies were evident when comparing the efficacy of interventions using BIA-based estimates of lean tissue mass against radiological assessment modalities. Body weight, BIA and DEXA-based endpoints have been most frequently used in cancer cachexia trials. Although the optimal endpoints cannot be determined from this review, body weight, alongside measurements from radiological body composition analysis, would seem appropriate. The choice of radiological modality is likely to be dependent on the trial setting, population and intervention in question. CT and magnetic resonance imaging, which have the ability to accurately discriminate tissue types, are likely to be more sensitive and provide greater detail. Endpoints are of particular importance when aligned with the intervention's mechanism of action and/or intended patient benefit.

Access, acceptance and adherence to cancer prehabilitation: a mixed-methods systematic review

PURPOSE

The purpose of this systematic review is to better understand access to, acceptance of and adherence to cancer prehabilitation.

METHODS

MEDLINE, CINAHL, PsychINFO, Embase, Physiotherapy Evidence Database, ProQuest Medical Library, Cochrane Library, Web of Science and grey literature were systematically searched for quantitative, qualitative and mixed-methods studies published in English between January 2017 and June 2023. Screening, data extraction and critical appraisal were conducted by two reviewers independently using Covidence™ systematic review software. Data were analysed and synthesised thematically to address the question 'What do we know about access, acceptance and adherence to cancer prehabilitation, particularly among socially deprived and minority ethnic groups?' The protocol is published on PROSPERO CRD42023403776 RESULTS: Searches identified 11,715 records, and 56 studies of variable methodological quality were included: 32 quantitative, 15 qualitative and nine mixed-methods. Analysis identified facilitators and barriers at individual and structural levels, and with interpersonal connections important for prehabilitation access, acceptance and adherence. No study reported analysis of facilitators and barriers to prehabilitation specific to people from ethnic minority communities. One study described health literacy as a barrier to access for people from socioeconomically deprived communities.

CONCLUSIONS

There is limited empirical research of barriers and facilitators to inform improvement in equity of access to cancer prehabilitation.

IMPLICATIONS FOR CANCER SURVIVORS

To enhance the inclusivity of cancer prehabilitation, adjustments may be needed to accommodate individual characteristics and attention given to structural factors, such as staff training. Interpersonal connections are proposed as a fundamental ingredient for successful prehabilitation.

Updates in Cancer Cachexia: Clinical Management and Pharmacologic Interventions

Despite a better understanding of the mechanisms causing cancer cachexia (CC) and development of promising pharmacologic and supportive care interventions, CC persists as an underdiagnosed and undertreated condition. CC contributes to fatigue, poor quality of life, functional impairment, increases treatment related toxicity, and reduces survival. The core elements of CC such as weight loss and poor appetite should be identified early. Currently, addressing contributing conditions (hypothyroidism, hypogonadism, and adrenal insufficiency), managing nutrition impact symptoms leading to decreased oral intake (nausea, constipation, dysgeusia, stomatitis, mucositis, pain, fatigue, depressed mood, or anxiety), and the addition of pharmacologic agents when appropriate (progesterone analog, corticosteroids, and olanzapine) is recommended. In Japan, the clinical practice has changed based on the availability of Anamorelin, a ghrelin receptor agonist that improved lean body mass, weight, and appetite-related quality of life (QoL) compared to a placebo, in phase III trials. Other promising therapeutic agents currently in trials include Espindolol, a non-selective β blocker and a monoclonal antibody to GDF-15. In the future, a single therapeutic agent or perhaps multiple medications targeting the various mechanisms of CC may prove to be an effective strategy. Ideally, these medications should be incorporated into a multimodal interdisciplinary approach that includes exercise and nutrition.

Perspectives and experiences of leisure-time physical activity in adults with stage 4 cancer: a qualitative interpretive-description study

PURPOSE

Leisure-time physical activity (LTPA) can be beneficial for individuals with advanced cancer, but little is known on how to tailor rehabilitation strategies targeting LTPA in cancer care. Our objective was to explore perspectives and experiences of LTPA in people with stage 4 cancer.

MATERIALS AND METHODS

Guided by interpretive-description methodology, our qualitative study consisted of individual, semi-structured interviews with 20 Canadian adults diagnosed with stage 4 cancer. Interviews were transcribed verbatim and analyzed inductively.

RESULTS

The participants' median age was 51.5 (range, 35-73) years. Cancer types included breast (n = 12), lung (n = 4), and other (n = 4). Participants highlighted their experiences of LTPA as diverse and complex, impacted by individual and cancer-related factors. They emphasized being intentional with LTPA through activity planning and modification. LTPA participation was linked to physical well-being, social connections, and meanings of accomplishment and loss. Many participants desired personalized support related to LTPA, that is integrated, interprofessional, and accessible in cancer care.

CONCLUSION

The experiences of LTPA for people with stage 4 cancer are personal and connected to health and psychosocial meanings. Further efforts in rehabilitation are needed to address the challenges faced by people with advanced cancer and optimize safe, meaningful participation in LTPA.IMPLICATIONS FOR REHABILITATIONExperiences of leisure-time physical activity in individuals with stage 4 cancer are personal and linked to health benefits and psychosocial meanings.Activity participation frequently involves consideration of cancer-related symptoms, management of risks, and intentional planning and modification of activities.Trained rehabilitation professionals integrated in cancer care may be well suited to support people with stage 4 cancer through personalized activity recommendations.This research can help inform future clinical, research, and educational efforts in rehabilitation aimed at targeting physical activity in individuals with advanced cancer.

Clinical Relevance of Physical Function Outcomes in Cancer Cachexia

Managing clinical manifestations of cancer/treatment burden on functional status and quality of life remains paramount across the cancer trajectory, particularly for patients with cachexia who display reduced functional capacity. However, clinically relevant criteria for classifying functional impairment at a single point in time or for classifying meaningful functional changes subsequent to disease and/or treatment progression are lacking. This unmet clinical need remains a major obstacle to the development of therapies for cancer cachexia. This review aims to describe current literature-based evidence for clinically meaningful criteria for (1) functional impairment at a single timepoint between cancer patients with or without cachexia and (2) changes in physical function over time across interventional studies conducted in patients with cancer cachexia. The most common functional assessment in cross-sectional and interventional studies was hand grip strength (HGS). We observed suggestive evidence that an HGS deficit between 3 and 6 kg in cancer cachexia may display clinical relevance. In interventional studies, we observed that long-duration multimodal therapies with a focus on skeletal muscle may benefit HGS in patients with considerable weight loss. Future studies should derive cohort-specific clinically relevant criteria to confirm these observations in addition to other functional outcomes and investigate appropriate patient-reported anchors.

Bridging gaps in cancer cachexia Care: Current insights and future perspectives

Cachexia is characterized by severe weight loss and skeletal muscle depletion, and is a threat to cancer patients by worsening their prognosis. International guidelines set indications for the screening and diagnosis of cancer cachexia and suggest interventions (nutritional support, physical exercise, and pharmacological treatments). Nevertheless, real-life experience not always aligns with such indications. We aimed to review the current state of the field and the main advancements, with a focus on real-life clinical practice from the perspectives of oncologists, nutrition professionals, and radiologists. Pragmatic solutions are proposed to improve the current management of the disease, emphasizing the importance of increasing awareness of clinical nutrition's benefits, fostering multidisciplinary collaboration, promoting early identification of at-risk patients, and leveraging available resources. Given the distinct needs of patients who are receiving oncologic anti-cancer treatments and those in the follow-up phase, the use of tailored approaches is encouraged. The pivotal role of healthcare professionals in managing patients in active treatment is highlighted, while patient and caregiver empowerment should be strengthened in the follow-up phase. Telemedicine and web-based applications represent valuable tools for continuous monitoring of patients, facilitating timely and personalized intervention through effective communication between patients and healthcare providers. These actions can potentially improve the outcomes, well-being, and survival of cancer patients with cachexia.

Approaching the Sarcopenic Patient with Nonalcoholic Steatohepatitis-related Cirrhosis

Sarcopenia is a well-known complication of chronic liver disease (CLD), and it is almost always observed in patients with cirrhosis, at least in those with decompensated disease. Since nonalcoholic fatty liver disease (NAFLD), recently renamed metabolic dysfunction-associated steatotic liver disease (MASLD), is becoming the leading cause of end-stage liver disease, a new scenario characterized by the frequent coexistence of NAFLD, obesity, and sarcopenia is emerging. Although it is not yet resolved whether the bidirectional relationship between sarcopenia and NAFLD subtends causal determinants, it is clear that the interaction of these two conditions is associated with an increased risk of poor outcomes. Notably, during the course of CLD, deregulation of the liver-muscle-adipose tissue axis has been described. Unfortunately, owing to the lack of properly designed studies, specific therapeutic guidelines for patients with sarcopenia in the context of NAFLD-related CLD have not yet been defined. Strategies aimed to induce the loss of fat mass together with the maintenance of lean body mass seem most appropriate. This can be achieved by properly designed diets integrated with specific nutritional supplementations and accompanied by adequate physical exercise. Future studies aiming to add to the knowledge of the correct assessment and approach to sarcopenia in the context of NAFLD-related CLD are eagerly awaited.

Advancing cancer cachexia diagnosis with -omics technology and exercise as molecular medicine

Muscle atrophy exacerbates disease outcomes and increases mortality, whereas the preservation of skeletal muscle mass and function play pivotal roles in ensuring long-term health and overall quality-of-life. Muscle atrophy represents a significant clinical challenge, involving the continued loss of muscle mass and strength, which frequently accompany the development of numerous types of cancer. Cancer cachexia is a highly prevalent multifactorial syndrome, and although cachexia is one of the main causes of cancer-related deaths, there are still no approved management strategies for the disease. The etiology of this condition is based on the upregulation of systemic inflammation factors and catabolic stimuli, resulting in the inhibition of protein synthesis and enhancement of protein degradation. Numerous necessary cellular processes are disrupted by cachectic pathology, which mediate intracellular signalling pathways resulting in the net loss of muscle and organelles. However, the exact underpinning molecular mechanisms of how these changes are orchestrated are incompletely understood. Much work is still required, but structured exercise has the capacity to counteract numerous detrimental effects linked to cancer cachexia. Primarily through the stimulation of muscle protein synthesis, enhancement of mitochondrial function, and the release of myokines. As a result, muscle mass and strength increase, leading to improved mobility, and quality-of-life. This review summarises existing knowledge of the complex molecular networks that regulate cancer cachexia and exercise, highlighting the molecular interplay between the two for potential therapeutic intervention. Finally, the utility of mass spectrometry-based proteomics is considered as a way of establishing early diagnostic biomarkers of cachectic patients.

Addressing cancer anorexia-cachexia in older patients: Potential therapeutic strategies and molecular pathways

Cancer cachexia (CC) syndrome, a feature of cancer-associated muscle wasting, is particularly pronounced in older patients, and is characterised by decreased energy intake and upregulated skeletal muscle catabolic pathways. To address CC, appetite stimulants, anabolic drugs, cytokine mediators, essential amino acid supplementation, nutritional counselling, cognitive behavioural therapy, and enteral nutrition have been utilised. However, pharmacological treatments that have also shown promising results, such as megestrol acetate, anamorelin, thalidomide, and delta-9-tetrahydrocannabinol, have been associated with gastrointestinal and cardiovascular complications. Emerging evidence on the efficacy of probiotics in modulating gut microbiota also presents a promising adjunct to traditional therapies, potentially enhancing nutritional absorption and systemic inflammation control. Additionally, low-dose olanzapine has demonstrated improved appetite and weight management in older patients undergoing chemotherapy, offering a potential refinement to current therapeutic approaches. This review aims to elucidate the molecular mechanisms underpinning CC, with a particular focus on the role of anorexia in exacerbating muscle wasting, and to propose pharmacological and non-pharmacological strategies to mitigate this syndrome, particularly emphasising the needs of an older demographic. Future research targeting CC should focus on refining appetite-stimulating drugs with fewer side-effects, specifically catering to the needs of older patients, and investigating nutritional factors that can either enhance appetite or minimise suppression of appetite in individuals with CC, especially within this vulnerable group.

A dose-response meta-analysis of randomized clinical trials investigating the effects of omega-3 supplementation on body weight in patients with cancer cachexia

BACKGROUND

Cachexia is one of the side effects of cancer diseases that can be reduced weight, and lower overall survival. Weight loss has been associated with adverse outcomes in both cancer patients and patients with benign diseases. There is no definitive treatment for fully reverse cachexia. studies showed higher levels of inflammatory markers in patient with cachectic cancer. Therefore, this study aimed to investigate the dose-response effects of omega-3 as an anti-inflammatory supplement on body weight in patients with cancer cachexia.

METHODS

Online databases including PubMed, Scopus, and Web of Science were systematically searched by relevant keywords up to January 2022. Random effect analysis was applied to perform meta-analysis. Subgroup analyses were performed to find heterogeneity sources. Quality assessment was conducted using Revised Cochrane Collaboration's tool II. Trim and fill analysis were also carried out in case of the presence of publication bias. The certainty in the evaluations was assessed by the GRADE approach.

RESULTS

Omega-3 supplementation resulted in a significant increase of body weight in patients with cancer cachexia when the age of study participants was ≥67 years and the baseline weight of them was ≤60 kg (WMD = 0.99; 95 % CI: 0.06, 1.92 and WMD = 1.22; 95 % CI: 0.14, 2.30, respectively). Also, there was a non-significant linear relationship between the dosage of omega-3 supplementation and body weight in patients with cancer cachexia.

CONCLUSION

Omega-3 supplementation may be a promising agent to increase body weight in patients with cancer cachexia. Also, a non-significant linear relationship between the dosage of omega-3 supplementation and body weight was found in these patients.

Weight loss of 5% or more after lobectomy for lung cancer via minimally invasive approaches is associated with poor prognosis

INTRODUCTION

We analyzed the association between postoperative weight loss (WL), preoperative body mass index (BMI), and prognosis in patients with lung cancer who underwent lobectomy using minimally invasive approaches.

METHODS

Weight change in 325 patients who underwent radical lobectomy for non-small cell lung cancer was assessed at 3, 6, and 12 months postoperatively and compared to preoperative weight. Patients were divided into three groups according to their preoperative BMI interquartile range: low BMI ≤20.3 kg/m2 , middle BMI 20.4-24.4 kg/m2 , and high BMI ≥24.5 kg/m2 . Postoperative WL ≥5% was evaluated with reference to frailty.

RESULTS

There were no significant differences in pathological findings, postoperative complications, or postoperative hospital stay among the three groups. Thirty all-cause deaths and 39 cancer recurrences occurred. Within the first year after surgery, WL of any grade was observed in 229 patients (70.5%) and WL ≥5% in 86 patients (26.5%). Postoperative WL of any grade within 1 year after surgery was not associated with OS and RFS (both p > .05). However, WL ≥5% within 1 year after surgery was associated with worse OS and RFS (p = .007 and .006, respectively). WL ≥5% within 1 year after surgery was more common in the low BMI group (p = .045). There was no difference in OS and RFS among the BMI groups in patients with WL ≥5% and those without WL ≥5% (all p > .05).

CONCLUSION

WL ≥5% was associated with poor prognosis after lobectomy via minimally invasive approaches. Weighing is a useful prognostic marker that can be easily self-checked.

Predictors of efficacy of anamorelin in patients with non‑small cell lung cancer and cachexia: A retrospective study

Anamorelin, a ghrelin receptor agonist, is approved in Japan for the treatment of cachexia in patients with lung and gastrointestinal cancer. However, there is limited research on the usefulness of anamorelin in clinical settings, therefore, the present study evaluated its efficacy using patient characteristics. A total of 40 patients with non-small cell lung cancer and cachexia who were prescribed anamorelin in the Department of Respiratory Medicine, Hirosaki University Graduate School of Medicine (Aomori, Japan) between July 2021 and November 2022, were retrospectively assessed. Anamorelin was prescribed at a dose of 100 mg once daily to patients who had lost >5% of their body weight within 6 months. All patients were weighed before treatment and those who continued anamorelin treatment for 12 weeks were also weighed at 12 weeks. A logistic regression analysis was used to analyze the association between background characteristics and early discontinuation of treatment with anamorelin (within 4 weeks). The median age was 67 years (range, 36-88), and 65% of the patients were male. There were 24 patients (60.0%) with an Eastern Cooperative Oncology Group Performance Status (ECOG-PS) score 1, 11 patients (27.5%) with an ECOG-PS score 2 and five patients (12.5%) with an ECOG-PS score 3. The early discontinuation group included 11 patients (27.5%). An ECOG-PS score ≥2 (odds ratio, 7.85; 95% confidence interval, 1.43-43.21; P=0.018) was associated with early discontinuation. A total of 18/40 patients (45.0%) were able to continue anamorelin treatment for 12 weeks, and the mean change in body weight was +2.31 kg, which was a significant change from the weight recorded at baseline (P=0.027). The mean changes in lean body mass and soft lean mass between baseline and 12 weeks were +1.97 kg (P=0.14) and +1.26 kg (P=0.15), respectively. The results from the present study indicate that anamorelin is unlikely to be useful for patients with a poor general condition (ECOG-PS score ≥2).

Advances in the management of pancreatic cancer

Pancreatic cancer remains among the malignancies with the worst outcomes. Survival has been improving, but at a slower rate than other cancers. Multimodal treatment, including chemotherapy, surgical resection, and radiotherapy, has been under investigation for many years. Because of the anatomical characteristics of the pancreas, more emphasis on treatment selection has been placed on local extension into major vessels. Recently, the development of more effective treatment regimens has opened up new treatment strategies, but urgent research questions have also become apparent. This review outlines the current management of pancreatic cancer, and the recent advances in its treatment. The review discusses future treatment pathways aimed at integrating novel findings of translational and clinical research.

Exosomal EIF5A derived from Lewis lung carcinoma induced adipocyte wasting in cancer cachexia

Cancer cachexia is a systemic inflammation-driven syndrome, characterized by muscle atrophy and adipose tissue wasting, with progressive weight loss leading to serious impairment of physiological function. Extracellular vesicles (EVs) derived from cancer cells play a significant role in adipocyte lipolysis, yet the mechanism remain uneclucidated. In this study, EVs derived from Lewis lung carcinoma (LLC) cells were extracted and characterized. 3T3-L1 and HIB1B adipocytes were cultured with conditioned medium or EVs from LLC, and LLC cells were used to establish a cancer cachexia mouse model. EVs derived from LLC cells were taken up by 3T3-L1 and HIB1B adipocytes, and derived exosomal EIF5A protein-induced lipolysis of adipocytes. High level of EIF5A was expressed in EVs from LLC cells, exosomal EIF5A is linked to lipid metabolism. Elevated expression of EIF5A is associated with shorter overall survival in lung cancer patients. Western blots, glycerol release and Oil red O staining assays were used to evaluate lipolysis of adipocytes. The reduction of lipolysis in 3T3-L1 and HIB1B adipocytes is achieved through silencing EIF5A or treating with pharmacologic inhibitor GC7 in vitro, and suppressing the expression of EIF5A in LLC cells by infected with shRNA or GC7 treatment partly alleviated white and brown adipose tissue lipolysis in vivo. Mechanistically, EIF5A directly binds with G protein-coupled bile acid receptor 1 (GPBAR1) mRNA to promote its translation and then activates cAMP response element binding protein (CREB) signaling pathway to induce lipolysis. This study demonstrates that exosomal EIF5A from LLC cells, with hypusinated EIF5A, has a lipolytic effect on adipocyte and adipose tissues in cancer cachexia model. Exosomal EIF5A could be involved in lipolysis and these findings indicate that a novel regulator and potential target for cachexia treatment.

Non-steroidal anti-inflammatory drugs for treatment of cancer cachexia: A systematic review

Cancer cachexia (CC) is a multifactorial syndrome driven by inflammation, defined by ongoing loss of skeletal muscle mass (with or without loss of fat mass) that cannot be fully reversed by conventional nutritional support. CC leads to progressive functional impairment, with its clinical management complicated and limited therapeutic options available. The objective of this review was to assess the efficacy and safety of non-steroidal anti-inflammatory drugs (NSAIDs) on patient-centred outcomes in patients with CC. In 2013, two systematic reviews concluded that there was insufficient evidence to recommend NSAIDs for clinical management of CC outside of clinical trials. However, clinical trials of multi-component CC interventions have included NSAIDs as an intervention component, so an up-to-date assessment of the evidence for NSAIDs in the treatment of CC is warranted. Four databases (MEDLINE, EMBASE, CENTRAL and CINAHL) and three trial registers (clinicaltrials.gov, WHO ICTRP and ISRCTN) were searched on 16 December 2022. Randomized controlled trials (RCTs) comparing any NSAID (any dose or duration) with a control arm, in adult patients with CC, reporting measures of body weight, body composition, nutrition impact symptoms, inflammation, physical function or fatigue, were eligible for inclusion. Primary outcomes (determined with patient involvement) were survival, changes in muscle strength, body composition, body weight and quality of life. Included studies were assessed for risk of bias using the Revised Cochrane risk-of-bias tool for randomized trials. Five studies were included, which investigated Indomethacin (n = 1), Ibuprofen (n = 1) and Celecoxib (n = 3). Four studies were judged to be at high risk of bias for all outcomes, with one study raising concerns for most outcomes. Considerable clinical and methodological heterogeneity amongst the studies meant that meta-analysis was not appropriate. There was insufficient evidence to determine whether Indomethacin or Ibuprofen is effective or safe for use in patients with CC; RCTs with lower risk of bias are needed. Celecoxib studies indicated it was safe for use in this population at the doses tested (200-400 mg/day) but found contrasting results regarding efficacy, potentially reflecting heterogeneity amongst the studies. There is inadequate evidence to recommend any NSAID for CC. While current clinical trials for CC treatments are shifting towards multi-component interventions, further research to determine the efficacy and safety of NSAIDs alone is necessary if they are to be included in such multi-component interventions. Furthermore, the lack of data on patient-determined primary outcomes in this review highlights the need for patient involvement in clinical trials for CC.

Association between Immune Checkpoint Inhibitor Treatment Outcomes and Body Composition Factors in Metastatic Renal Cell Carcinoma Patients

INTRODUCTION

Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of metastatic renal cell carcinoma (mRCC); however, validating body composition-related biomarkers for their efficacy remains incomplete. We evaluated the association between body composition-related markers and the prognosis of patients with mRCC who received ICI-based first-line therapies.

PATIENTS AND METHODS

We retrospectively investigated 60 patients with mRCC who underwent ICI-based therapy as their first-line treatment between 2019 and 2023. Body composition variables, including skeletal muscle, subcutaneous fat, and visceral fat indices, were calculated using baseline computed tomography scans. Sarcopenia was defined according to sex-specific cut-off values of the skeletal mass index. The associations between body composition indices and objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) were evaluated.

RESULTS

Patients with sarcopenia had lower ORR and DCR than those without sarcopenia (33.3% vs. 61.1%, p = 0.0436 and 52.4% vs. 94.4%, p = 0.0024, respectively). Patients with sarcopenia had a significantly shorter median PFS (14 months vs. not reached, p = 0.0020) and OS (21 months vs. not reached, p = 0.0023) than patients without sarcopenia did. Sarcopenia was a significant predictor of PFS (hazard ratio [HR], 4.31; 95% confidence interval [CI], 1.65-14.8; p = 0.0018) and OS (HR, 5.44; 95% CI, 1.83-23.4; p = 0.0013) along with poor IMDC risk. No association was found between the subcutaneous, visceral, and total fat indices and the therapeutic effect of ICI-based therapy.

CONCLUSIONS

Sarcopenia was associated with a lower response and shorter survival rates in patients with mRCC who received first-line ICI-based therapy.

The role of the nurse in meeting the educational needs for self-care in cachectic cancer patients and their family caregivers: A scoping review

Objective

To give an overview of what is known about the nurse contribution to education in self-care by people with cancer cachexia and their family caregivers. Nurse-led patient education can help patients and their family caregivers to manage cancer symptoms, cancer treatments, and treatment side effects.

Methods

This scoping review explored the extent to which nurse-led education has become part of the multimodal management of cancer cachexia. It is based on a systematic search of Medline, Embase, CINAHL, APA PsycINFO, and the Cochrane Library. Search limits were English language, date ranges from January 2015 to March 2023, and adults 18 years and older.

Results

A total of 6370 titles were screened, 127 papers and conference abstracts were selected for full-text examination, and 9 publications were included in the review. The analysis found the nurses within the multidisciplinary cancer cachexia care team, like other healthcare professionals, do not have a shared understanding of cancer cachexia and its management. For nurses to be confident and competent in the provision of nurse-led cachexia education, they themselves need evidence-based education in cachexia care and how to tailor education according to cachexia stage, symptoms, emotional response, and social circumstance.

Conclusions

Nurses with the knowledge and confidence to provide cancer cachexia education for their patients can potentially play an important role in the management of cancer cachexia and mitigation of cachexia-related problems.

Exercise-based interventions for cancer cachexia: A systematic review of randomised and non-randomised controlled trials

Objective

Cachexia is a multifactorial syndrome characterised by involuntary weight loss and functional limitation. There is a strong theoretical rationale for the use of exercise in the management of cachexia, and evidence of benefit from exercise in general cancer patients. However, clinical studies of exercise interventions in cancer cachexia are limited. We aimed to synthesise current evidence on the delivery, acceptability, safety and outcomes of exercise interventions for adults with cancer cachexia.

Methods

We conducted a systematic review. Four databases were searched up to February 2023 for randomised (RCTs) and non-randomised (NRCTs) controlled studies. Eligibility and quality were independently assessed by two authors. Data on intervention components and structure, participant flow and adherence were tabulated. Clinical outcome data on body stature and composition, muscle strength, functional performance, and health-related quality of life were synthesised using effect direction plots.

Results

Twelve studies (9 RCTs, 3 NRCTs) involving a total of 898 patients (study range 20-374) as part of a multicomponent approach. Median programme completion was 75% (range 43%-100%) and adherence was generally high. Five adverse events were considered possibly related to an intervention, including muscle or joint pain, breathlessness on exertion. Overall, 12/16 (75%) outcomes demonstrated a positive direction of effect on body stature and composition, 8/10 (80%) on muscle strength, 14/22 (64%) on functional performance, and 3/8 (38%) on health-related quality of life. Multicomponent interventions showed more consistent effects on body stature, and resistance training interventions on muscle strength.

Conclusions

Exercise interventions appear to be safe and acceptable to people with cancer cachexia. Positive effects from exercise are more consistently observed for body stature or composition and muscle strength outcomes, than in functional capacity and health-related quality of life. The synergistic effects of exercise with other cachexia interventions, including drugs, should be examined in future robust studies.

Factors associated with early discontinuation of anamorelin in patients with cancer-associated cachexia

PURPOSE

Cancer-associated cachexia, a multifactorial syndrome involving loss of muscle mass and anorexia, is an unremitting problem for cancer patients. Anamorelin has become available for cancer-associated cachexia, but early discontinuation is common in clinical practice. This study aimed to explore factors related to the early discontinuation of anamorelin and its relationship to survival.

PATIENTS AND METHODS

This prospective, observational study of multimodal clinical practice involved patients who took anamorelin (100 mg) for cancer-associated cachexia at Aichi Medical University Hospital between 14 May 2021 and 31 March 2022. In July 2022, clinical data were extracted from electronic clinical records. Patients who discontinued anamorelin less than 4 weeks after initiation were defined as the early discontinuation group, and their clinical data and survival time were compared with those of the continuation group. This study was approved by the Ethics Committee of the university (approval no. 2021-124).

RESULTS

Of the 42 patients treated with anamorelin, 40 (median age 72.5 years, median BMI 18.7 kg/m2) were analyzed, including 13 with non-small cell lung cancer, and 12 with pancreatic, 8 with colorectal, and 7 with gastric cancers. On univariate analysis, the early discontinuation group included more patients with worse performance status (PS) (p=0.028), low prognostic nutritional index (PNI) (p=0.001), and no concomitant anticancer drugs (p=0.003). On multivariate analysis, PS and PNI were related to anamorelin continuation. Survival time was significantly shorter in the early discontinuation group (p=0.039).

CONCLUSION

Worse PS and low PNI were associated with early discontinuation of anamorelin. Longer survival time was observed in the continuation group.

Physical function endpoints in cancer cachexia clinical trials: Systematic Review 1 of the cachexia endpoints series

In cancer cachexia trials, measures of physical function are commonly used as endpoints. For drug trials to obtain regulatory approval, efficacy in physical function endpoints may be needed alongside other measures. However, it is not clear which physical function endpoints should be used. The aim of this systematic review was to assess the frequency and diversity of physical function endpoints in cancer cachexia trials. Following a comprehensive electronic literature search of MEDLINE, Embase and Cochrane (1990-2021), records were retrieved. Eligible trials met the following criteria: adults (≥18 years), controlled design, more than 40 participants, use of a cachexia intervention for more than 14 days and use of a physical function endpoint. Physical function measures were classified as an objective measure (hand grip strength [HGS], stair climb power [SCP], timed up and go [TUG] test, 6-min walking test [6MWT] and short physical performance battery [SPPB]), clinician assessment of function (Karnofsky Performance Status [KPS] or Eastern Cooperative Oncology Group-Performance Status [ECOG-PS]) or patient-reported outcomes (physical function subscale of the European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaires [EORTC QLQ-C30 or C15]). Data extraction was performed using Covidence and followed PRISMA guidance (PROSPERO registration: CRD42022276710). A total of 5975 potential studies were examined and 71 were eligible. Pharmacological interventions were assessed in 38 trials (54%). Of these, 11 (29%, n = 1184) examined megestrol and 5 (13%, n = 1928) examined anamorelin; nutritional interventions were assessed in 21 trials (30%); and exercise-based interventions were assessed in 6 trials (8%). The remaining six trials (8%) assessed multimodal interventions. Among the objective measures of physical function (assessed as primary or secondary endpoints), HGS was most commonly examined (33 trials, n = 5081) and demonstrated a statistically significant finding in 12 (36%) trials (n = 2091). The 6MWT was assessed in 12 trials (n = 1074) and was statistically significant in 4 (33%) trials (n = 403), whereas SCP, TUG and SPPB were each assessed in 3 trials. KPS was more commonly assessed than the newer ECOG-PS (16 vs. 9 trials), and patient-reported EORTC QLQ-C30 physical function was reported in 25 trials. HGS is the most commonly used physical function endpoint in cancer cachexia clinical trials. However, heterogeneity in study design, populations, intervention and endpoint selection make it difficult to comment on the optimal endpoint and how to measure this. We offer several recommendations/considerations to improve the design of future clinical trials in cancer cachexia.

Evaluation and management of body composition changes in cancer patients

Wasting in cancer patients has long been recognized as a condition that adversely affects cancer patients' quality of life, treatment tolerance, and oncological outcomes. Historically, this condition was mainly evaluated by changes in body weight. However, this approach is not quite accurate because body weight is the overall change of all body compartments. Conditions such as edema and ascites can mask the severity of muscle and adipose tissue depletion. Changes in body composition assessment in cancer patients have historically been underappreciated because of the limited availability of measurement tools. As more evidence highlighting the importance of body composition has emerged, it is imperative to apply a more precise evaluation of nutritional status and a more targeted approach to provide nutritional support for cancer patients. In this review, we will discuss the modalities for evaluating body composition and how to manage body composition changes in cancer patients.

[Sarcopenia in patients with pancreatic cancer, an independant prognostic factor]

BACKGROUND

Pancreatic cancer is despite modern diagnostic tools and treatment regimen associated with poor outcome. Many patients show cachexia and sarcopenia.

METHODS

In a retrospective analysis the SMI (cm²/m²) was measured by determining the skelettal muscle area in a computed tomography image at lumbar vertebrae 3. Further clinical parameters were measured to determine the outcome.

RESULTS

The mean survival after diagnosis in the population with sarcopenia was significantly lower (14,4 vs 17,7 months, p=0,046). Significantly shorter survival was also seen for higher age (p=0,006), no tumor resection (p=0,004), metastases (p=0,002) and high CA19-9 level (p=0,002) CONCLUSION: Sarcopenia is an indipendant prognostic factor in patients with pancreatic cancer. SMI should be measured clinical practice and further studies are necessary to asses a potential therapeutic strategy.

The Incidence and Management of Cancer-Related Anorexia During Treatment with Vascular Endothelial Growth Factor Receptor-Tyrosine Kinase Inhibitors

Cancer-related anorexia is a common complication and frequently occurs in cancer patients treated with vascular endothelial growth factor receptor-tyrosine kinase inhibitors (VEGFR-TKIs). Anorexia contributes to malnutrition, body weight loss, and cachexia in affected patients. Furthermore, patients who experience anorexia have worse outcomes than those who maintain their appetite, highlighting the importance of managing anorexia and related symptoms. However, as the causes of anorexia are both diverse and interconnected, there have been challenges in evaluating and implementing effective interventions. In this review, we described the contributing factors to cancer-related anorexia and reviewed recent literature for the frequency of anorexia symptoms in patients treated with VEGFR-TKIs. Additionally, we evaluated the evidence for current interventions and the potential benefits of multimodal and multidisciplinary approaches to care. The frequency of anorexia symptoms in patients who received VEGFR-TKIs ranged from 14%-58% for all-grade anorexia and 0%-6% for grade 3 or 4 anorexia. While many of the interventions for cancer-related anorexia have minimal benefit or adverse events, recent advances in our understanding of cancer-related anorexia suggest that multimodal therapy with multidisciplinary care is a promising avenue of investigation. Several studies currently underway are anticipated to further assess the effectiveness of multimodal approaches.

Cancer Cachexia: Underlying Mechanisms and Potential Therapeutic Interventions

Cancer cachexia, a multifactorial metabolic syndrome developed during malignant tumor growth, is characterized by an accelerated loss of body weight accompanied by the depletion of skeletal muscle mass. This debilitating condition is associated with muscle degradation, impaired immune function, reduced functional capacity, compromised quality of life, and diminished survival in cancer patients. Despite the lack of the known capability of fully reversing or ameliorating this condition, ongoing research is shedding light on promising preclinical approaches that target the disrupted mechanisms in the pathophysiology of cancer cachexia. This comprehensive review delves into critical aspects of cancer cachexia, including its underlying pathophysiological mechanisms, preclinical models for studying the progression of cancer cachexia, methods for clinical assessment, relevant biomarkers, and potential therapeutic strategies. These discussions collectively aim to contribute to the evolving foundation for effective, multifaceted counteractive strategies against this challenging condition.

Feasibility and safety of exercise during chemotherapy in people with gastrointestinal cancers: a pilot study

PURPOSE

Sarcopenia is a poor prognostic factor in cancer patients, and exercise is one of the treatments to improve sarcopenia. However, there is currently insufficient evidence on whether exercise can improve sarcopenia in patients with advanced cancers. This study examined the feasibility of exercise in advanced gastrointestinal (GI) cancer patients treated with palliative chemotherapy.

METHODS

Between 2020 and 2021, 30 patients were enrolled in a resistance and aerobic exercise program for six weeks. The exercise intervention program (EIP) consisted of low, moderate, and high intensity levels. Patients were asked to select the intensity level according to their ability. The primary endpoint was the feasibility of the EIP measured by compliance during the six weeks. A compliance of over 50% was considered acceptable. The secondary endpoints were changes in weight and muscle mass, safety, quality of life (QoL) and overall survival (OS).

RESULTS

The median age of the study's participants was 60 (30-77). The total compliance to the EIP was 63.3% (19/30 patients). Sixteen (53.3%) patients had a compliance of over 80%. The attrition rate was 30.0% (9/30). The mean exercise time was 41.4 min, and the aerobic exercise was 92.3% and the resistant exercise was 73.7%, and both exercise was 66.5%. Most patients performed the moderate intensity level exercises at home or near their home. The mean skeletal muscle index (SMI) was 43.5 cm2/m2 pre-chemotherapy and 42.2 cm2/m2 after six weeks of chemotherapy, with a decrease of -1.2 ± 2.8 cm2/m2 (-3.0%) (p = 0.030). In the poor compliance group, the mean SMI decrease was -2.8 ± 3.0 cm2/m2 which was significantly different (p = 0.033); however, in the good compliance group, the mean SMI decrease was -0.5 ± 2.5 cm2/m2 which was maintained over the six weeks (p = 0.337). The good compliance group had a significantly longer median OS compared with the poor compliance group (25.3 months vs. 7.9 months, HR = 0.306, 95% CI = 0.120-0.784, p = 0.014). The QoL showed a better score for insomnia (p = 0.042). There were no serious adverse events.

CONCLUSIONS

The EIP during palliative chemotherapy in advanced GI cancer patients showed good compliance. In the good compliance group, muscle mass and physical functions were maintained for six weeks. The EIP was safe, and the QoL was maintained. Based on this study, further research in exercise intervention in advanced cancer patients is needed.

Update on the treatment of cancer cachexia

Cancer cachexia is a complex multifaceted syndrome involving functional impairment and changes in body composition that cannot be reversed by nutritional support. Cancer cachexia is characterized by decreased skeletal muscle mass, increased lipolysis, and decreased food intake. Cancer cachexia decreases chemotherapy tolerance as well as quality of life. However, because no fully effective interventions are available, cancer cachexia remains an unmet need in cancer treatment. In recent years, several discoveries and treatments for cancer cachexia have been studied, and guidelines have been published. We believe that the development of effective strategies for the diagnosis and treatment of cancer cachexia will lead to breakthroughs in cancer treatment.

Omega-3 polyunsaturated fatty acids in sarcopenia management: A network meta-analysis of randomized controlled trials

Sarcopenia frequently occurs with aging and leads to major adverse impacts on activities of daily living and quality of life in elderly individuals. Omega-3 polyunsaturated fatty acid (omega-3 PUFAs) supplements are considered promising therapeutic agents for sarcopenia management; however, the evidence remains inconsistent. We reviewed randomized controlled trials (RCTs) about omega-3 PUFA supplementation in patients with sarcopenia or in those at high risk for sarcopenia. Network meta-analysis (NMA) procedures were conducted using a frequentist model. The primary outcomes were (1) upper-extremity muscle strength and (2) lower-extremity physical function. The NMA of 16 RCTs showed that the high-dose (more than 2.5 g/day omega-3 PUFAs) group yielded the greatest improvement in both upper-extremity muscle strength and lower-extremity physical function [compared to placebo/standard care groups, standardized mean difference (SMD)= 1.68, 95% confidence interval (95%CI)= 0.03-3.33, and SMD= 0.73, 95%CI= 0.16-1.30, respectively], and the effects were reaffirmed in subgroup analyses of placebo-controlled RCTs or those excluding concurrent resistance training programs. None of the investigated omega-3 PUFAs supplementation was associated with significantly increased skeletal muscle mass, fat mass, or overall body weight. Our findings provide a basis for future large-scale RCTs to investigate the dose effects and clinical application of omega-3 PUFA supplementation in sarcopenia management. TRIAL REGISTRATION: The current study was approved by the Institutional Review Board of the Tri-Service General Hospital, National Defense Medical Center, Taipei, Taiwan (TSGHIRB No. B-109-29) and registered in PROSPERO (CRD42022347161).

Measuring What Is Meaningful in Cancer Cachexia Clinical Trials: A Path Forward With Digital Measures of Real-World Physical Behavior

PURPOSE

The burden of cancer cachexia on patients' health-related quality of life, specifically their physical functioning, is well documented, but clinical trials thus far have failed to show meaningful improvement in physical functioning. The purpose of this review is to summarize existing methods of assessing physical function in cancer cachexia, outline a path forward for measuring what is meaningful to patients using digital measures derived from digital health technologies (DHTs), and discuss the current landscape of digital measures from the clinical and regulatory standpoint.

DESIGN

For this narrative review, peer-reviewed articles were searched on PubMed, clinical trials records were searched on clinicaltrials.gov, and records of digital measures submitted for regulatory qualification were searched on the US Food and Drug Administration's Drug Development Tool Qualification Program database.

RESULTS

There are gaps in assessing aspects of physical function that matter to patients. Existing assessment methods such as patient-reported outcomes and objective performance outcomes have limitations, including their episodic nature and burden to patients. DHTs such as wearable sensors can capture real-world physical behavior continuously, passively, and remotely, and may provide a more comprehensive picture of patients' everyday functioning. Recent regulatory submissions showcase potential clinical implementation of digital measures in various therapeutic areas.

CONCLUSION

Digital measures of real-world physical behavior present an opportunity to detect and demonstrate improvements in physical functioning in cancer cachexia, but evidence-based development is critical. For their use in clinical and regulatory decision making, studies demonstrating meaningfulness to patients as well as feasibility and validation are necessary.

Nurse-Supervised Exercise for People with Stage IV Cancer: The EFICANCER Randomized Clinical Trial

OBJECTIVES

To assess the effectiveness of the EFICANCER individualized and supervised exercise program for people with gastrointestinal, breast, or non-small cell lung stage IV cancer, in terms of quality of life and functional capacity.

DATA SOURCES

Randomized controlled clinical trial with two parallel groups: EFICANCER (n = 47) and control (n = 43). Both groups received standard oncological care. In addition, the EFICANCER group participated in a nurse-supervised exercise program. Primary outcome was cancer-specific (EORTC QLQ-C30 questionnaire) and general quality of life (SF-36) at baseline and after 2, 6, and 12 months. Secondary outcomes were functional capacity (6-minute walking test), strength, and fatigue. The evolution in both groups was compared over 12 months using mixed-effect longitudinal models; 74.47% of patients completed at least one session of the program. At 12 months, EFICANCER group had better scores in cancer-related quality of life, with a difference between groups of 15.7 points (95% confidence interval 4.4 to 25.9) and in functional capacity, with a difference of 4.5 points (95% confidence interval -0.5 to 9.5). No significant differences in any other secondary variables were observed.

CONCLUSION

The EFICANCER primary care nurse supervised exercise program is safe and feasible and improves cancer patient's outcomes.

IMPLICATIONS FOR NURSING PRACTICE

Providing the best care and trying to improve the quality of life of cancer patients are essential parts of nursing practice. Eficancer adds a new dimension to nursing practice by providing greater attention and care to patients during treatment through the supervision of physical exercise, thereby contributing to improve the quality of life of this population.

Harms of exercise training in patients with cancer undergoing systemic treatment: a systematic review and meta-analysis of published and unpublished controlled trials

Background

Exercise is recommended for people with cancer. The aim of this study was to evaluate the harms of exercise in patients with cancer undergoing systemic treatment.

Methods

This systematic review and meta-analysis included published and unpublished controlled trials comparing exercise interventions versus controls in adults with cancer scheduled to undergo systemic treatment. The primary outcomes were adverse events, health-care utilization, and treatment tolerability and response. Eleven electronic databases and trial registries were systematically searched with no date or language restrictions. The latest searches were performed on April 26, 2022. The risk of bias was judged using RoB2 and ROBINS-I, and the certainty of evidence for primary outcomes was assessed using GRADE. Data were statistically synthesised using pre-specified random-effect meta-analyses. The protocol for this study was registered in the PROESPERO database (ID: CRD42021266882).

Findings

129 controlled trials including 12,044 participants were eligible. Primary meta-analyses revealed evidence of a higher risk of some harms, including serious adverse events (risk ratio [95% CI]: 1.87 [1.47-2.39], I2 = 0%, n = 1722, k = 10), thromboses (risk ratio [95% CI]: 1.67 [1.11-2.51], I2 = 0%, n = 934, k = 6), and fractures (risk ratio [95% CI]: 3.07 [3.03-3.11], I2 = 0%, n = 203, k = 2) in intervention versus control. In contrast, we found evidence of a lower risk of fever (risk ratio [95% CI]: 0.69 [0.55-0.87], I2 = 0% n = 1109, k = 7) and a higher relative dose intensity of systemic treatment (difference in means [95% CI]: 1.50% [0.14-2.85], I2 = 0% n = 1110, k = 13) in intervention versus control. For all outcomes, we downgraded the certainty of evidence due to imprecision, risk of bias, and indirectness, resulting in very low certainty of evidence.

Interpretation

The harms of exercise in patients with cancer undergoing systemic treatment are uncertain, and there is currently insufficient data on harms to make evidence-based risk-benefits assessments of the application of structured exercise in this population.

Funding

There was no funding for this study.

Clinical usefulness of the Patient-Generated Subjective Global Assessment and modified Glasgow Prognostic Score in decision making concerning the indication of enteral nutritional therapy in patients with incurable cancer receiving palliative care

OBJECTIVES

This study aimed to identify the clinical usefulness of assessing nutritional status using validated tools for the indication of enteral nutrition for patients with incurable cancer in palliative care.

METHODS

In this prospective cohort study, patients were assessed for nutritional risk using the Patient-Generated Subjective Global Assessment and for cancer cachexia (CC) using the modified Glasgow Prognostic Score upon enrollment and after ∼30 d. The outcome was stable or improved Karnofsky Performance Status. Logistic regression models were used, providing the odds ratio (OR) and 95% confidence interval (CI).

RESULTS

A total of 180 patients participated. The only nutritional status parameter that was associated with function was CC. The less severe the CC, the more likely Karnofsky Performance Status was to remain stable or improve over 30 d (non-cachectic: OR = 1.95; 95% CI, 1.01-3.47; malnourished: OR = 1.06; 95% CI, 1.01-1.42). Furthermore, white skin color (OR = 1.79; 95% CI, 1.04-2.47), higher educational level (OR = 1.39; 95% CI, 1.13-2.78), and inadequate calorie intake (OR = 1.96; 95% CI, 1.02-2.81) were also associated with the outcome.

CONCLUSIONS

Using the modified Glasgow Prognostic Score to identify the existence and severity of CC, which is associated with function, has the potential to help clinical decision making concerning the indication of enteral nutrition in patients with incurable cancer receiving palliative care.
