A progressive postresection walking program significantly improves fatigue and health-related quality of life in pancreas and periampullary cancer patients

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.

Efficacy of aerobic and resistance exercises on cancer pain: A meta-analysis of randomised controlled trials

Purpose

To evaluate effects of aerobic and resistance exercises for cancer-related pain in adults with and surviving cancer. Secondary objectives were to a) evaluate the effect of exercise on fatigue, psychological function, physical function, b) assess fidelity to exercise.

Design

A systematic search of MEDLINE, EMBASE, AMED, CINAHL and Cochrane Central Register of Controlled Trials was conducted to identify randomised controlled trials (RCTs) comparing aerobic and/or resistance exercise to control groups. The primary endpoint were changes in cancer-related pain intensity from baseline to post intervention. Meta-regression analysis evaluated predictors for heterogeneity between study findings. Tolerability was defined as reporting of exercise-induced adverse events while fidelity evaluated by reported intervention dropout.

Results

Twenty-three RCTs including 1954 patients (age 58 ± 8.5 years; 78 % women); 1087 (56 %) and 867 (44 %) allocated to aerobic/resistance exercise therapy and control group, respectively. Exercise therapy was associated with small to moderate decreases in cancer-related pain compared to controls (SMD = 0.38, 95 % CI: 0.17, 0.58). Although there was significant heterogeneity between individual and pooled study effects (Q = 205.25, p < 0.0001), there was no publication bias. Meta-regression including supervision, age, duration and exercise type as moderators showed no significant differences in reported outcomes. Analysis of secondary outcomes revealed a moderate effect for improvements in physical function, fatigue and psychological symptoms.

Conclusions

Aerobic and resistance exercises are tolerable and effective adjunct therapies to reduce cancer-related pain while also improving physical function, fatigue and mood. Future RCTs of dose, frequency, compliance and exercise type in specific cancer settings are required.

Phase 1 randomized trial of inpatient high-intensity interval training after major surgery

BACKGROUND

High-intensity interval training (HIT) can provide physiologic benefits and may improve postoperative recovery but has not been evaluated in inpatients. This study aimed to evaluate the safety and tolerability of HIT after major surgery.

METHODS

We performed a phase I randomized study comparing HIT with low-intensity continuous ambulation (40 m) during the initial inpatient stay after major surgery at a large academic center. Clinicopathologic and pre- and post-exercise physiologic data were captured. Perceived exertion was measured throughout the intervention.

RESULTS

Twenty-two subjects were enrolled and randomized with 90% (20 subjects, 10 per arm) completing all aspects of the study. One patient declined participation in the exercise intervention. The HIT and continuous ambulation groups were relatively similar in terms of median age (65.5 vs 63.5), female sex (20% vs 40%), White race (90% vs 90%), having a cancer diagnosis (100% vs 80%), undergoing gastrointestinal surgery (60% vs 80%), median Karnofsky score (60 vs 60), and ability to independently ambulate preoperatively (100% vs 90%). All subjects completed the exercise without protocol deviation, cohort crossover, or safety events. Compared with the continuous ambulation group, the HIT group had higher end median perceived exertion (5.0 [IQR, 5.5] vs 3.0 [IQR, 1.8]), shorter overall time to complete assigned exercise (56.6 seconds vs 91.8 seconds), and a trend toward higher median gait speed over 40 m (0.71 m/s vs 0.44 m/s, P = .126).

CONCLUSION

HIT in the hospitalized postoperative patient is safe and may be implemented to help promote positive physiologic outcomes and recovery.

Effects of Exercise Training on Patient-Specific Outcomes in Pancreatic Cancer Patients: A Scoping Review

BACKGROUND

International guidelines have already highlighted the beneficial effects of exercise in common cancer entities. However, specific recommendations for pancreatic cancer are still missing. This scoping review aimed to evaluate the impact of exercise training on patient-specific outcomes in pancreatic cancer patients.

METHODS

A literature search was undertaken using PubMed, Web of Science, and Cochrane Library. We included randomized controlled trials (RCTs) published before August 2023 with structured exercise interventions during or after pancreatic cancer treatment.

RESULTS

Seven articles that prescribed home-based or supervised exercise with aerobic or resistance training or both were reviewed. The results indicate that exercise is feasible and safe in pancreatic cancer patients. Furthermore, exercise was associated with improved quality of life, cancer-related fatigue, and muscle strength. Concerning other outcomes, heterogeneous results were reported. We identified a lack of evidence, particularly for patients with advanced pancreatic cancer.

CONCLUSION

Exercise interventions in pancreatic cancer patients are feasible and can lead to improved quality of life, cancer-related fatigue, and muscle strength. However, further studies with larger sample sizes are needed to clarify the potential of exercise in pancreatic cancer, in particular for advanced stages.

Evaluating the effectiveness of mindfulness alone compared to exercise and mindfulness on fatigue in women with gynaecology cancer (GEMS): Protocol for a randomised feasibility trial

BACKGROUND

In 2020 Globocan reported nearly 1.4 million new cases of gynaecology cancer worldwide. Cancer related fatigue has been identified as a symptom that can be present for gynaecology cancer patients many years after treatment. The current evidence around the management of this symptom suggests that exercise has the most positive outcome. However, some ambiguity remains around the evidence and whether it can address all areas of fatigue effectively. More recently, other interventions such as mindfulness have begun to show a favourable response to the management of symptoms for cancer patients. To date there has been little research that explores the feasibility of using both these interventions together in a gynaecology cancer population. This study aims to explore the feasibility of delivering an intervention that involves mindfulness and mindfulness and exercise and will explore the effect of this on fatigue, sleep, mood and quality of life.

METHODS/DESIGN

This randomised control trial will assess the interventions outcomes using a pre and post design and will also include a qualitative process evaluation. Participants will be randomised into one of 2 groups. One group will undertake mindfulness only and the other group will complete exercise and mindfulness. Both groups will use a mobile application to complete these interventions over 8 weeks. The mobile app will be tailored to reflect the group the participants have drawn during randomisation. Self-reported questionnaire data will be assessed at baseline prior to commencing intervention and at post intervention. Feasibility will be assessed through recruitment, adherence, retention and attrition. Acceptability and participant perspective of participation (process evaluation), will be explored using focus groups.

DISCUSSION

This trial will hope to evidence and demonstrate that combination of two interventions such as mindfulness and exercise will further improve outcomes of fatigue and wellbeing in gynaecology cancer. The results of this study will be used to assess (i) the feasibility to deliver this type of intervention to this population of cancer patients using a digital platform; (ii) assist this group of women diagnosed with cancer to manage fatigue and other symptoms of sleep, mood and impact their quality of life.

Feasibility of delivering supervised exercise training following surgical resection and during adjuvant chemotherapy for pancreatic ductal adenocarcinoma (PRECISE): a case series

INTRODUCTION

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive neoplasm, with surgical resection and adjuvant chemotherapy the only curative treatment. Treatment-related toxicities place a considerable burden on patients although exercise training has shown promise is helping to manage such adversities and facilitate rehabilitation. The feasibility and safety of exercise training as a supportive therapy during adjuvant chemotherapy remains unknown.

METHODS

Patients with PDAC were screened post-surgical resection and enrolled in a 16-week, progressive, concurrent exercise programme alongside their chemotherapy regimen. Feasibility was the primary objective detailing recruitment, retention and adherence rates throughout as well as the safety and fidelity of the intervention. Secondarily, the impact on functional fitness and patient-reported outcomes was captured at baseline, post-intervention and 3-month follow up.

RESULTS

Eight patients consented to participate in this trial, with five proceeding to enrol in exercise training. Concurrent exercise training is feasible and safe during adjuvant chemotherapy and prevented an expected decline in functional fitness and patient-reported outcomes during this time.

DISCUSSION

This case series provides preliminary evidence that concurrent exercise training during adjuvant therapy is safe, feasible and well tolerated, preventing an expected decline in functional fitness, muscular strength and health-related quality of life (HRQoL). Given the adverse effects of treatment, these findings are promising and provide further evidence for the inclusion of exercise training as a standard of care for surgical rehabilitation and managing treatment-related toxicities. Future research should explore the impact of exercise training during neoadjuvant chemotherapy, with prehabilitation now standard practice for borderline resectable disease.

The Effect of Exercise on Pain in People with Cancer: A Systematic Review with Meta-analysis

INTRODUCTION

Cancer-related pain is common and undertreated. Exercise is known to have a pain-relieving effect in non-cancer pain.

OBJECTIVES

This systematic review aimed to evaluate (1) the effect of exercise on cancer-related pain in all cancers, and (2) whether the effect of exercise differed according to exercise mode, degree of supervision, intervention duration and timing (during or after cancer treatment), pain types, measurement tool and cancer type.

METHODS

Electronic searches were undertaken in six databases to identify exercise studies evaluating pain in people with cancer, published prior to 11 January 2023. All stages of screening and data extraction were conducted independently by two authors. The Cochrane risk of bias tool for randomised trials (RoB 2) was used and overall strength of evidence was assessed using the GRADE approach. Meta-analyses were performed overall and by study design, exercise intervention and pain characteristics.

RESULTS

In total, 71 studies reported in 74 papers were eligible for inclusion. The overall meta-analysis included 5877 participants and showed reductions in pain favouring exercise (standardised mean difference - 0.45; 95% confidence interval - 0.62, - 0.28). For most (> 82%) of the subgroup analyses, the direction of effect favoured exercise compared with usual care, with effect sizes ranging from small to large (median effect size - 0.35; range - 0.03 to - 1.17). The overall strength of evidence for the effect of exercise on cancer-related pain was very low.

CONCLUSION

The findings provide support that exercise participation does not worsen cancer-related pain and that it may be beneficial. Better pain categorisation and inclusion of more diverse cancer populations in future research would improve understanding of the extent of benefit and to whom.

Physical and psychological symptom burden in patients and caregivers during follow-up care after curative surgery for cancers in the pancreas, bile ducts or duodenum

BACKGROUND

The primary aim was to assess Health Related Quality of Life (HRQoL), anxiety and depression in patients and caregivers during follow-up care after curative treatment for cancer in the pancreas, duodenum, or bile ducts. The secondary aim was to assess dyadic coping and the burden of being a caregiver.

MATERIALS AND METHODS

In this prospective observational cohort study, we included patients and caregivers at first follow-up visit to conduct the following: Demographic characteristics, The European Organization for Research and Treatment of Cancer Quality of Life, the pancreas and bile duct module, EQ5D 3L, GAD-7 and PHQ-9 at baseline, and at six and nine-months follow-up visit. Demographic characteristics, Dyadic Coping Inventory and Zarit Caregiver Burden Questionnaire were conducted at baseline and at nine-months of follow-up visit.

RESULTS

The response rate was 42% with 104 of the 248 invited patients completing the questionnaires at baseline: 78 (75% of 104) after six and 69 (66% of 104) after nine months. The median (Q25,75) time for inclusion was 33.6 (13.4, 38) and 29.1 (18.3, 36) weeks after surgery for patients with pancreatic or duodenal cancer, and bile duct cancer, respectively. The response rate of caregivers was 88% with 75 of 85 completing the questionnaires. Fifty percent of patients with pancreatic or duodenal cancer had diarrhea at baseline. After six and nine months, this increased to 75%. Fatigue was the most prominent symptom in patients with bile duct cancer after nine months with 25% of patients scoring this as a clinical symptom.

CONCLUSIONS

The study highlights the need to systematically screen physical and psychological symptoms in patients and caregivers during follow-up care after treatment for cancer in the pancreas, duodenum and bile ducts. Symptom management during follow-up care should be prioritized by clinicians.

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.

Institute-based nurse-led care versus home-based resistance training for patients with acute pancreatitis: Clinical outcomes analysis

Surgeries may have worse clinical outcomes in pancreatitis. In our institute surgical procedure is barely used surgery to treat pancreatitis nowadays. Chinese guidelines recommended regular exercise for severe pancreatitis. The objectives of the current study were to compare nurse-led resistance training at the institute against usual care provided to patients with acute pancreatitis for favorable clinical outcome measures. For acute pancreatitis, patients (≥18 years, of age) received 6 months of resistance training in the garden of the institute under the supervision of registered nurses (NR cohort, n = 102), or received 6 months of resistance training at their home by themselves according to a training manual (HR cohort, n = 120) or received 6 months of usual care only (UC cohort, n = 120). Fewer numbers patients died in the follow-up period in the NR cohort than those of the HR (8 vs 21, P = .0447) and the UC (8 vs 32, P = .0046) cohorts. The frequency of rehospitalization of patients due to any of the reasons in the follow-up period was fewer for patients of the NR cohort than those of the HR and the UC cohorts (P < .05 for both). Hospitalization of patients due to any of the reasons in the follow-up period was fewer for patients of the HR cohort than those of the UC cohort (P < .05). A 52 median score was the quality of life of patients before the start of the non-treatment intervention(s). After 6 months of non-treatment intervention(s), patients of the NR cohort improved their quality of life as compared to their initial quality of life (P < .001), those of HR cohort (P < .05), and those of UC cohort (P < .001). The quality of life of patients with severe pancreatitis after the surgical procedure was worse. Six months of nurse-assisted resistant training at the institute has significant improvement on the quality of life of patients in the follow-up periods of acute pancreatitis. Resistant training at the institute would improve the quality of life of patients with acute pancreatitis (Level of Evidence: IV; Technical Efficacy Stage: 5).

The role of exercise for pain management in adults living with and beyond cancer: a systematic review and meta-analysis

BACKGROUND

Pain is a common side effect of cancer or cancer treatment that negatively impacts biopsychosocial wellbeing and quality of life. Exercise is a potential intervention to manage pain that is safe and has multiple benefits. The objective was to determine the role of exercise in cancer pain management.

METHODS

We completed a systematic review and meta-analysis of exercise interventions in adults with any type or stage of cancer by searching Ovid MEDLINE®, Embase, APA PsycInfo, the Cochrane Central Register of Controlled Trials, CINAHL, and SPORTDiscus. We included experimental and quasi-experimental designs where pain was measured as an outcome. Data synthesis included narrative and tabular summary. A meta-analysis was performed on studies powered to detect the effect of exercise on pain. Study quality was evaluated using the Cochrane risk of bias tool and certainty of evidence was evaluated using the GRADE tool.

RESULTS

Seventy-six studies were included. Studies were predominantly conducted in breast cancer and exercise usually included a combination of aerobic and strength training. Ten studies were included in the meta-analysis demonstrating a significant effect for exercise in decreasing pain (estimated average standard mean difference (SMD) was g =  - 0.73 (95% CI: - 1.16 to - 0.30)); however, the overall effect prediction interval was large. Overall risk of bias for most studies was rated as some concerns and the grading of evidence certainty was low.

CONCLUSION

There are limitations in the evidence for exercise to manage cancer-related pain. Further research is needed to understand the role of exercise in a multimodal pain management strategy.

Telemedicine and Pancreatic Cancer: A Systematic Review

Introduction: Pancreatic cancer requires a multidisciplinary approach in a high-volume center for all the steps of the diagnostic-therapeutic course. However, the most experienced centers are not evenly distributed throughout the country causing a real "health migration" that involves patients and families with relevant economic, time, and energy costs to bear. The COVID-19 pandemic had a deep impact on surgical and oncological care and the travel limits due to COVID-related restrictions, have delayed the care of cancer patient living far from the referral centers. In this scenario, several telemedicine approaches have been proposed to reduce the distance between clinicians and patients and to allow a fast and effective access to care even for patients distant from referral centers. The aim of the study is to analyze the evidence and describe the current utility of telemedicine tool for patients with pancreatic cancer. Methods: We systematically searched the literature in the following databases: Web of Science, PubMed, Scopus, and MEDLINE. The inclusion criteria were article describing a telemedicine intervention (virtual visits, telephone follow-up/counseling, mobile or online apps, telemonitoring) and focusing on adult patients with pancreatic cancer at any stage of the disease. Results: In total, 846 titles/abstracts were identified. Following quality assessment, the review included 40 studies. Telemedicine has been proposed in multiple clinical settings, demonstrating high levels of patient and health professional satisfaction. Conclusion: Successful telemedicine applications in patients with pancreatic cancer are telerehabilitation and nutritional assessment, remote symptom control, teledischarge after pancreatic surgery, tele-education and medical mentoring regarding pancreatic disease as well as telepathology.

Comparison of three exercise interventions with and without gemcitabine treatment on pancreatic tumor growth in mice: No impact on tumor infiltrating lymphocytes

Exercise has been shown to slow pancreatic tumor growth, but whether exercise interventions of differing volume or intensity yield differential effects on tumor outcomes is unknown. In this study, we compared three exercise training interventions implemented with and without chemotherapy on pancreatic tumor growth in mice. Methods: Male C57BL/6 mice (6-8 weeks old) were subcutaneously inoculated with pancreatic ductal adenocarcinoma tumor cells (PDAC 4662). Upon tumor detection, mice received gemcitabine 15 mg/kg intraperitoneally 3 days/week and were assigned to exercise: high volume continuous exercise (HVCE), low volume continuous exercise (LVCE), high intensity interval training (HIIT), or sedentary (SED). HVCE ran at 12 m/min for 45 min and LVCE for 15 min, 5 days/week. HIIT ran 1-min at 20 m/min, followed by 1-min walking at 8 m/min for 20 total intervals, 3 days/week. SED did not run. Additional sets of inoculated mice were assigned to the exercise interventions but did not receive gemcitabine. Tumor volume was measured every other day for 2 weeks; tumor-infiltrating lymphocytes were assessed by flow cytometry 3-week post-inoculation. Results: Tumor growth did not differ between groups that received gemcitabine (F(3, 34) = 1.487; p = 0.235; η2 = 0.116). In contrast, tumor growth differed between groups not provided gemcitabine (F(3,14) = 3.364; p = 0.049, η2 = 0.419), with trends for slower growth in LVCE than SED (p = 0.088) and HIIT (p = 0.084). Groups did not differ in tumor infiltrating lymphocytes. Conclusion: Contrary to our hypotheses, the exercise interventions compared here did not further reduce pancreatic tumor growth beyond that provided by gemcitabine. However, in mice not receiving gemcitabine, there was a trend for reduced tumor growth in LVCE.

Systematic Review of Functional Outcomes in Cancer Rehabilitation

OBJECTIVE

To systematically review the evidence regarding rehabilitation interventions targeting optimal physical or cognitive function in adults with a history of cancer and describe the breadth of evidence as well as strengths and limitations across a range of functional domains.

DATA SOURCES

PubMed, Cumulative Index to Nursing and Allied Health Plus, Scopus, Web of Science, and Embase. The time scope was January 2008 to April 2019.

STUDY SELECTION

Prospective, controlled trials including single- and multiarm cohorts investigating rehabilitative interventions for cancer survivors at any point in the continuum of care were included, if studies included a primary functional outcome measure. Secondary data analyses and pilot/feasibility studies were excluded. Full-text review identified 362 studies for inclusion.

DATA EXTRACTION

Extraction was performed by coauthor teams and quality and bias assessed using the American Academy of Neurology (AAN) Classification of Evidence Scheme (class I-IV).

DATA SYNTHESIS

Studies for which the functional primary endpoint achieved significance were categorized into 9 functional areas foundational to cancer rehabilitation: (1) quality of life (109 studies), (2) activities of daily living (61 studies), (3) fatigue (59 studies), (4) functional mobility (55 studies), (5) exercise behavior (37 studies), (6) cognition (20 studies), (7) communication (10 studies), (8) sexual function (6 studies), and (9) return to work (5 studies). Most studies were categorized as class III in quality/bias. Averaging results found within each of the functional domains, 71% of studies reported statistically significant results after cancer rehabilitation intervention(s) for at least 1 functional outcome.

CONCLUSIONS

These findings provide evidence supporting the efficacy of rehabilitative interventions for individuals with a cancer history. The findings should be balanced with the understanding that many studies had moderate risk of bias and/or limitations in study quality by AAN criteria. These results may provide a foundation for future work to establish clinical practice guidelines for rehabilitative interventions across cancer disease types.

Effect of exercise on pancreatic cancer patients during treatment: a scoping review of the literature

INTRODUCTION

Exercise can lower the risk of developing pancreatic cancer and has the potential to improve physical fitness and quality of life in patients with the disease. Yet, the effects of exercise training during pancreatic cancer treatment remain poorly characterized. This hampers the development of evidence-based disease-specific exercise recommendations.

PURPOSE

The purpose of this review was to describe and interpret the effect of exercise on physiological, QoL, and cancer-specific outcomes reported in clinical trials among pancreatic cancer patients during treatment.

METHODS

We conducted a scoping review of the literature according to the framework proposed by Arksey and O'Malley. Articles published prior to December 2021 were retrieved from PubMed, EMBASE, and Scopus. We only included studies that prescribed structured cardiorespiratory and/or resistance exercise in pancreatic cancer patients undergoing treatment.

RESULTS

A total of 662 references were retrieved, of which 24 are included in the review. Twelve articles were randomized controlled trials and 12 were single-arm trials. Overlap in the trials from which data were reported occurred in 16 articles. Moderate intensity exercise was most commonly prescribed, reported feasible for most patients, with potential to enhance physical fitness and QoL. However, exercise adherence and beneficial effects may diminish with disease progression. Limited evidence suggests exercise may benefit cancer-specific outcomes.

CONCLUSION

The results of this review indicate that exercise is feasible during pancreatic cancer treatment. Exercise can also improve physical fitness and QoL. However, its beneficial effects may fall with advanced disease and more rigorous research is needed to develop precise exercise protocols for this population.

Consensus Statement on Mandatory Measurements for Pancreatic Cancer Trials for Patients With Resectable or Borderline Resectable Disease (COMM-PACT-RB): A Systematic Review and Delphi Consensus Statement

Importance

Pancreatic cancer is the third most common cause of cancer death; however, randomized clinical trials (RCTs) of survival in patients with resectable pancreatic cancer lack mandatory measures for reporting baseline and prognostic factors, which hampers comparisons between outcome measures.

Objective

To develop a consensus on baseline and prognostic factors to be used as mandatory measurements in RCTs of resectable and borderline resectable pancreatic cancer.

Evidence Review

We performed a systematic literature search of the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, and Embase for RCTs on resectable and borderline resectable pancreatic cancer with overall survival as the primary outcome. We produced a systematic summary of all baseline and prognostic factors identified in the RCTs. A Delphi panel that included 13 experts was surveyed to reach a consensus on mandatory and recommended baseline and prognostic factors.

Findings

The 42 RCTs that met inclusion criteria reported a total of 60 baseline and 19 prognostic factors. After 2 Delphi rounds, agreement was reached on 50 mandatory baseline and 20 mandatory prognostic factors for future RCTs, with a distinction between studies of neoadjuvant vs adjuvant treatment.

Conclusion and Relevance

This findings of this systematic review and international expert consensus have produced this Consensus Statement on Mandatory Measurements in Pancreatic Cancer Trials for Resectable and Borderline Resectable Disease (COMM-PACT-RB). The baseline and prognostic factors comprising the mandatory measures will facilitate better comparison across RCTs and eventually will enable improved clinical practice among patients with resectable and borderline resectable pancreatic cancer.

Effects of intensive physiotherapy on Quality of Life (QoL) after pancreatic cancer resection: a randomized controlled trial

BACKGROUND

Patients have significantly lower QoL scores after pancreatic resection due to cancer in the physical and psychological domains compared to healthy controls or other cancer patients. Intensified physiotherapy or physical training can increase QoL by reducing fatigue levels and improving physical functioning. However, data on the long-term effects of intensive or supervised physiotherapy is lacking. The aim of this exploratory study is the assessment of QoL in the intervention group, using various QoL questionnaires in their validated German translations and gather data on its feasibility in the context of chemotherapy with a follow-up of 12 months (and develop concepts to improve QoL after pancreatic cancer resection).

METHODS

Fifty-six patients (mean age: 66.4 ± 9.9 years) were randomized in this study to intervention (cohort A, n = 28) or control group (cohort B, n = 28). Intervention of intensified physiotherapy program consisted of endurance and muscle force exercises using cycle ergometer. In the control group physiotherapy was limited to the duration of the hospital stay and was scheduled for 20 min on 5 days per week. The clinical visits took place 2 days preoperatively, 1 week, 3 months, 6 months and 12 months postoperatively. Both groups attended the follow-up program. QoL was evaluated using the Short Physical Performance Battery (SPPB), Short Form-8 Health Survey (SF-8) and the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and pancreatic cancer-specific module QLQ-PAN26 questionnaires. The course of QoL was evaluated using a repeated measures ANOVA and a per protocol design.

RESULTS

Of the initial 56 randomized patients, 34 finished the 12 months follow-up period. There were no adverse events due to the intervention and 80% of patients in the intervention group where adherent. There was no significant influence on physical performance as measured by SPPB and SF-8 questionnaire. However, after 6 months patients in the intervention group regained their prior physical condition, whereas the control group did not. Intensive physiotherapy significantly influenced various factors of QoL measured with the C30 questionnaire positively, such as physical functioning (p = 0.018), role functioning (p = 0.036), and appetite loss (p = 0.037), even after 6 months. No negative effects in patients undergoing chemotherapy compared to those without chemotherapy was observed.

CONCLUSION

This first randomized controlled study with a 12-month follow-up shows that supervised physiotherapy or prescribed home-based exercise after pancreatic cancer resection is safe and feasible and should be proposed and started as soon as possible to improve certain aspects of QoL.

A review of physical activity in pancreatic ductal adenocarcinoma: Epidemiology, intervention, animal models, and clinical trials

Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest types of cancer, and the increasing incidence of PDAC may be related to the prevalence of obesity. Physical activity (PA), a method known to mitigate obesity by increasing total energy expenditure, also modifies multiple cellular pathways associated with cancer hallmarks. Epidemiologic evidence has shown that PA can lower the risk of developing a variety of cancers, reduce some of the detrimental side effects of treatments, and improve patient's quality of life during cancer treatment. However, little is known about the pathways underlying the correlations observed between PA interventions and PDAC. Moreover, there is no standard dose of PA intervention that is ideal for PDAC prevention or as an adjuvant of cancer treatments. In this review, we summarize relevant literature showing how PDAC patients can benefit from PA, the potential of PA as an adjuvant treatment for PDAC, the studies using preclinical models of PDAC to study PA, and the clinical trials to date assessing the effects of PA in PDAC.

Effects of Walking on Fatigue in Cancer Patients: A Systematic Review and Meta-analysis

BACKGROUND

Walking is a simple form of exercise that is easily accepted by patients. Exercise is one of the main ways to control cancer-related fatigue (CRF). However, there are conflicting data on the association between walking and severity of CRF.

OBJECTIVE

The aim of this study was to assess the overall effect of walking on CRF among adult cancer patients.

METHODS

Databases including PubMed, CINAHL, EMBASE, and Cochrane Library were systematically reviewed to identify suitable randomized controlled trials from inception to February 29, 2020. Two reviewers independently evaluated the risk of bias and extracted correlated data with Cochrane Handbook of Systematic Reviews on Interventions. The data analysis was performed by Review Manager 5.3.

RESULTS

A total of 12 studies with 1064 patients were identified. Integrated result analysis of walking yielded a statistically significant effect on CRF (standard mean difference [SMD], -0.66; 95% confidence interval [CI], -1.06 to -0.26). Subgroup analysis demonstrated that intervention time longer than 6 weeks (SMD, -0.89; 95% CI, -1.22 to -0.57) had a better effect on fatigue compared with that of less than 6 weeks (SMD, 0.03; 95% CI, -0.39 to 0.45). The study showed walking was statistically more effective than the control intervention in patients undergoing cancer treatment (SMD, -0.79; 95% CI, -1.16 to -0.42). Descriptive analysis also showed that walking was effective for cancer patients who completed treatment.

CONCLUSIONS

Walking is effective for CRF during and after cancer therapy.

IMPLICATIONS FOR PRACTICE

The results provide evidence for a general exercise form to relieve fatigue in cancer patients and facilitate support for future clinical trials and work.

Supportive therapy and complementary medicine in renal cell carcinoma

PURPOSE

As part of the German interdisciplinary S3-guideline "Diagnosis, Treatment and Followup of Renal Cell Carcinoma", this article aimes to provide guidance regarding the use of supportive therapy and complementary medicine in patients with advanced or metastatic renal cell carcinoma.

METHODS

The German interdisciplinary S3-guidelines are national clinical practice guidelines that implement the highest methodological quality of evidence-based medicine. Recommendations and evidence-based statements are provided according to available evidence.

RESULTS

Supportive and palliative care are important areas of tumor treatment and require knowledge on the management of a variety of issues. This article outlines the management of tumor-related symptoms such as pain, undesired treatment-related effects, palliative care and end-of-life care in patients with renal cell carcinoma.

CONCLUSION

Patients with advanced or metastatic renal cell carcinoma should have access to supportive and palliative care according to their individual needs. There is very limited evidence regarding the impact of complementary medicine for the treatment of patients with renal cell carcinoma.

Micronutritional status after pylorus preserving duodenopancreatectomy: analysis of data from a randomized controlled trial

Physical frailty and nutritional malassimilation are often observed after pancreaticoduodenectomy for pancreatic cancer. But long-term data concerning the course of micronutrient status is still missing. Micronutrient status after pylorus preserving pancreaticoduodenectomy with a follow-up of 12 months was evaluated using data of a randomized controlled trial. 47 patients were randomized with respect to the physiotherapy regimen they received (intensified physiotherapy: n = 22; standard physiotherapy: n = 25). Nutritional status was recorded preoperatively and postoperatively after one week, 3, 6 and 12 months. BMI, body fat measurement and albumin, lipid, iron and bone metabolism parameters, vitamins A, B1 B6 and B12, homocysteine, folic acid, and trace elements were measured. Laboratory values were analyzed descriptively. Differences between the groups were analyzed using the t-test in SPSS. For vitamin D, B1, B6 and iron a deficiency over time could be demonstrated with 50% of all patients or more being below normal range. The other laboratory values were in low normal range after 3 months and later. Significant differences between groups were found in cholesterol, HDL and selenium levels (corrected p-values < 0.033 in all cases). Vitamin D and iron should be supplemented postoperatively in the long term, and vitamin B1 and B6 substitution should be considered in symptomatic patients. Levels of malnutrition induced fatigue should be comparable between both groups. However, the role of nutritional status on other health-related aspects such as quality of life should be the focus of further studies.Trial Registration Number in the German Registry for Clinical Studies: DRKS00006786; Date of Registration: 01.10.2014.

Quality of Life Instruments and Trajectories After Pancreatic Cancer Resection: A Systematic Review

ABSTRACT

This systematic review aimed to investigate the instruments available to measure quality of life (QOL) after pancreatic cancer surgery and to describe short- and long-term QOL outcomes. A comprehensive literature search was completed using PubMed, Embase, and Medline from inception to March 2019. Studies investigating QOL outcomes in patients undergoing pancreatic cancer surgery who were 18 years or older were included. The main outcomes of interest were QOL instruments and short (≤6 months) and long term (>6 months) QOL outcomes. The overarching domains of physical, psychosocial, overall QOL, symptoms, and other were used to summarize QOL outcomes. Thirty-five studies reporting on 3573 patients were included. Fifteen unique QOL instruments were identified, of which 4 were disease-specific instruments. Most of the included studies reported no changes in QOL at short- and long-term follow-ups for the overarching domains. No difference in QOL outcomes was reported between different surgical approaches, except laparoscopic versus open distal pancreatectomy, and pancreaticoduodenectomy versus distal pancreatectomy. There are a wide range of instruments available to measure QOL outcomes in pancreatic cancer surgical patients, although only few are disease-specific. Most of the included studies reported no significant changes in QOL outcomes at short- or long-term follow-ups.

Outcomes Related to Activity Performance and Participation of Non-Pharmacological Cancer-Related Fatigue Interventions

Increased cancer survivorship means more people are living with cancer-related fatigue (CRF), which is associated with activity performance limitations, restricted participation in meaningful life roles, and reduced quality of life. To identify whether non-pharmacological interventions that are effective in minimizing CRF also have an impact on everyday activity performance and participation outcomes for adult cancer survivors. This is a systematic review with narrative synthesis. Eight databases were searched (Medline, CINAHL, PsychINFO, EMBASE, Scopus, OT Seeker, CENTRAL, Cochrane SR database), from 2000 to 2020 for randomized controlled trials of effective non-pharmacological CRF interventions in adult cancer survivors with fatigue. A total of 5,762 studies were identified of which 29 studies were reviewed. In 28 studies, quality of life was investigated as a primary or secondary outcome, where concepts of participation or activity performance were used. Review findings indicate there is insufficient evidence to determine whether activity performance and participation is affected by CRF interventions.

Perioperative exercise training for patients with gastrointestinal cancer undergoing surgery: A systematic review and meta-analysis

Exercise training is emerging as a supportive treatment strategy in surgical oncology, but its effects remain uncertain in patients with gastrointestinal cancer. The primary objective of this systematic review and meta-analysis was to evaluate the effects of perioperative exercise training on gastrointestinal cancer-specific mortality, recurrence, and surgical outcomes (postoperative complications, hospitalization, surgical stress) in patients with gastrointestinal cancer. Randomized or quasi-randomized controlled trials evaluating the effects of perioperative exercise training versus control in patients with GI cancer were eligible. MEDLINE, EMBASE, CENTRAL, CINAHL, PEDro, and SPORTDiscus were systematically searched on June 20, 2020. Data were synthesized using random-effects meta-analyses. Risk of bias was assessed using the Cochrane risk of bias tool 2, and the certainty of evidence was assessed using GRADE. Study selection, data extraction, risk of bias, and GRADE assessments were performed independently by two authors. Ten randomized controlled trials comprising 448 participants with gastrointestinal cancer were eligible. Meta-analyses indicated no statistical effects of exercise on postoperative complications (risk ratio: 1.11, 95% CI: 0.84; 1.47), readmissions (risk ratio: 2.76; 95% CI: 0.00, 9394.76), or postoperative length of stay (difference in means: -0.47, 95% CI: -17.2; 16.2 days). None of the eligible studies assessed gastrointestinal cancer-specific mortality or recurrence. Overall risk of bias was high or of some concerns in all studies, and the certainty of evidence was very low. The effects of perioperative exercise on cancer-specific and surgical outcomes are unknown in patients with gastrointestinal cancer due to lack of studies and very low certainty of evidence.

Changes in Physical Function and Effects on QOL in Patients after Pancreatic Cancer Surgery

This study examined the changes in physical function and quality of life (QOL) of postoperative patients with pancreatic cancer for 3 months after surgery and examined the factors affecting the QOL at the 3 months after surgery. Methods: This study comprised 32 pancreatic cancer patients who underwent surgery at our hospital. Among these patients, 20 patients for whom data was measured before surgery to 3 months after surgery were selected for statistical analyses: 8 males and 12 females, 69.8 ± 7.4 years. The preoperative and postoperative rehabilitation was given to patients under the guidance of a physiotherapist. Nutritional status, body composition, physical function, gait assessments, and QOL were investigated. Results: Body weight, body fat mass, body fat percentage, body mass index (BMI), and muscle mass significantly decreased 3 months after surgery compared with their respective preoperative values. The mean grip strength at the time of 3 months after the surgery had decreased significantly from 27.3 kg to 24.5 kg. The mean skeletal muscle mass index (SMI) had decreased significantly from 6.3 kg before surgery to 5.9 kg after the surgery. The QOL scores for global health status, physical, and role showed significant decreases 2 weeks after surgery compared with the respective preoperative scores. Significant improvements in these scores were observed 3 months after surgery compared with the respective scores 2 weeks after surgery. Physical function assessments after surgery were associated with QOL 3 months after surgery. Conclusion: Recovery of patients after pancreatic cancer surgery in body weight, BMI, body fat percentage, body fat percentage, muscle mass, SMI, and grip strength was not sufficient at the time of 3 months after surgery. It has been observed that physical function of patients has affected the improvement of QOL.

Preoperative In-Hospital Rehabilitation Improves Physical Function in Patients with Pancreatic Cancer Scheduled for Surgery

Low preoperative physical function in cancer patients is associated with postoperative complications; however, there have been no reports on the benefits of in-hospital preoperative rehabilitation on preoperative physical function in patients with pancreatic cancer. Therefore, the aim of this study was to quantitatively determine the effects of preoperative in-hospital rehabilitation provided under the supervision of a physiotherapist, on preoperative physical function in patients with pancreatic cancer. The study subjects were 26 patients (15 males, 11 females; age 71.2 ± 8.5 years, range: 51-87 years), including four patients with preoperative chemotherapy, scheduled for surgery for pancreatic cancer. Muscle strengthening exercises and aerobic exercises were conducted 11.9 ± 5.1 days prior to surgery. Cardiopulmonary exercise testing, 6-minute walk distance, and the Functional Independence Measure score were measured before and after the rehabilitation program. We also investigated the relation between the rehabilitation program and incidence of postoperative complications. All 26 study patients completed the preoperative rehabilitation program and no adverse events were noted. Peak oxygen uptake during cardiopulmonary exercise testing and 6-minute walk distance increased significantly after the rehabilitation program. The Functional Independence Measure score remained constant throughout the intervention. No wound infection, delirium, deep vein thrombosis, or respiratory complications were encountered postoperatively. In-hospital preoperative rehabilitation under the supervision of a physiotherapist significantly improved physical function and maintained physical activity in patients with pancreatic cancer. Such improvements may contribute toward preventing serious postoperative complications, resulting in better outcomes.

Diet and Exercise Interventions in Patients With Pancreatic Cancer: A Scoping Review

Diet and exercise interventions may help reverse malnutrition and muscle wasting common in pancreatic cancer. We performed a scoping review to identify the knowledge gaps surrounding diet and exercise interventions. We searched PubMed, Scopus, Cumulative Index to Nursing and Allied Health Literature, Embase, ProQuest Theses and Dissertations, and Google Scholar using the umbrella terms of "pancreatic cancer," "diet/nutrition," and "exercise." Included were articles reporting on ambulatory adults with diagnosed pancreatic cancer. Excluded were studies examining prevention and/or risk, animal, or cell lines. Of the 15,708 articles identified, only 62 met the final inclusion criteria. Almost half of the articles were randomized controlled studies (n = 27). Most studies were from the United States (n = 20). The majority examined dietary interventions (n = 41), with 20 assessing the use of omega-3 fatty acids. Exercise interventions were reported in 13 studies, with 8 examining a diet and exercise intervention. Most studies were small and varied greatly in terms of study design, intervention, and outcomes. We identified 7 research gaps that should be addressed in future studies. This scoping review highlights the limited research examining the effect of diet and exercise interventions in ambulatory patients with pancreatic cancer.

The effects of physical activity, fast-mimicking diet and psychological interventions on cancer survival: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Health professionals are often asked if non-pharmacological interventions prolong life. This review aims to evaluate the effects of physical activity, fast-mimicking diet (FMD) and psychological interventions on survival in all cancers.

METHODS

A systematic review and meta-analysis of randomized controlled trials (RCTs). Only RCTs of physical activity, FMD and psychological interventions (including counselling, cognitive and other psychotherapies) in cancer patients that reported survival outcomes were included.

DATA SOURCES

CENTRAL, MEDLINE, Embase, CINAHL, APA PsycINFO, Web of Science, ICTRP and ClinicalTrials.gov from inception to January 2020 were searched without language restrictions. The protocol was prospectively registered at PROSPERO (CRD42019160944).

RESULTS

Thirty-one RCTs (9 on physical activity and 22 on psychological interventions) were included in the final analysis after evaluation of 60,207 records from our initial search. No eligible RCT on FMD was reported. RCTs on group psychological interventions (41.9 %) and in patients with breast cancer (38.7 %) were the most common. Most evaluated short-term interventions and in primary or adjuvant settings. Only one of 9 (11 %) RCTs on physical activity and 8 of 22 (36 %) RCTs on psychological interventions were associated with improved overall survival. Only group psychological interventions in breast cancer had adequate number of RCTs to allow a meta-analysis to be performed. It demonstrated a trend towards improved overall survival (HR -0.20, 95 %CI -0.49 to 0.10), particularly in RCTs that evaluated long-term (>6 months) therapies (HR -0.29, 95 %CI -0.59 to 0.01).

CONCLUSION

Longer term interventions starting early in the patients' care journey in primary and adjuvant settings have shown the most promise for improving survival. Better designed RCTs including survival outcomes are particularly needed in non-breast cancers.

Exercise Medicine in the Management of Pancreatic Cancer: A Systematic Review

ABSTRACT

The aim of this study was to examine the health-related effects of exercise in patients with pancreatic cancer (PanCa) through a systematic review of current evidence. Studies were obtained through searching PubMed, Web of Science, PsycINFO, Embase, CINAHL Plus, and Cochrane Library databases with additional hand searches. All intervention-based studies were included if it involved (1) adult patients with PanCa, (2) exercise training, and (3) findings in quality of life, cancer-related fatigue, psychological distress, and physical function. The review protocol was registered in PROSPERO: CRD42020154684. Seven trials described in 9 publications were included consisting of 201 patients with early-stage and advanced PanCa. Participants were required to perform supervised and/or home-based, low- to moderate-intensity resistance and/or aerobic exercise for 12 to 35 weeks or duration of neoadjuvant therapy. There were no exercise-related adverse events with a reported retention rate of 71% to 90% and exercise attendance of 64% to 96%. The programs were consistently associated with improvements in cancer-related fatigue, psychological distress, and physical function, with mixed effects on quality of life. Exercise training seems to be safe and feasible and may have a beneficial effect on various physical and psychological outcomes in patients with PanCa. Further work with rigorous study designs is required to consolidate and advance current findings.

Exercise efficacy and prescription during treatment for pancreatic ductal adenocarcinoma: a systematic review

BACKGROUND

Surgical resection remains the only curative treatment for pancreatic cancer and is associated with significant post-operative morbidity and mortality. Patients eligible for surgery, increasingly receive neo-adjuvant therapy before surgery or adjuvant therapy afterward, inherently exposing them to toxicity. As such, optimizing physical function through exercise during treatment remains imperative to optimize quality of life either before surgery or during rehabilitation. However, current exercise efficacy and prescription in pancreatic cancer is unknown. Therefore, this study aims to summarise the published literature on exercise studies conducted in patients with pancreatic cancer undergoing treatment with a focus on determining the current prescription and progression patterns being used in this population.

METHODS

A systematic review of four databases identified studies evaluating the effects of exercise on aerobic fitness, muscle strength, physical function, body composition, fatigue and quality of life in participants with pancreatic cancer undergoing treatment, published up to 24 July 2020. Two reviewers independently reviewed and appraised the methodological quality of each study.

RESULTS

Twelve studies with a total of 300 participants were included. Heterogeneity of the literature prevented meta-analysis. Exercise was associated with improvements in outcomes; however, study quality was variable with the majority of studies receiving a weak rating.

CONCLUSIONS

High quality evidence regarding the efficacy and prescription of exercise in pancreatic cancer is lacking. Well-designed trials, which have received feedback and input from key stakeholders prior to implementation, are required to examine the impact of exercise in pancreatic cancer on key cancer related health outcomes.

Gastrointestinal side effects of upper gastrointestinal cancer surgery

In this chapter, we describe the gastrointestinal side effects of oesophagectomy, gastrectomy and pancreaticoduodenectomy for cancer, with a focus on long-term functional impairments and their management. Improvements in upper gastrointestinal cancer surgery have led to a growing group of long-term survivors. The invasive nature of these surgeries profoundly alters the upper gastrointestinal anatomy, with lasting implications for long-term function, and how these impairments may be treated. Successfully maintaining a high quality of survivorship requires multidisciplinary approach, with survivorship care plans focused on function as much as the detection of recurrence.

Factors associated with fatigue one month after surgery in patients with gastrointestinal cancer

OBJECTIVE

The purpose of this study was to examine the factors associated with the occurrence of cancer-related fatigue (CRF) one month after surgery in patients with gastrointestinal cancer.

METHOD

The study included 96 patients with gastrointestinal cancer (50 males and 46 females, mean age 62.7 ± 11.4 years). Data of the Cancer Fatigue Scale (CFS), 6-minute walk distance (6MWD), and hospital anxiety and depression scale (HADS) were obtained before surgery and one month after surgery. The subjects were divided into the following two groups: severe CRF group (CFS score of ≥19 points) and mild CRF group (CFS score of <19 points). Each parameter was compared between the severe and mild CRF groups. The factors associated with CRF were identified by logistic regression analysis involving factors with significant differences between the groups.

RESULT

The CFS score showed a significant interaction, and the CFS score, 6MWD, and HADS score showed significant differences both before and one month after surgery between the two groups. The CFS score was significantly higher in the severe CRF group than in the mild CRF group both before and one month after surgery. Additionally, the 6MWD was significantly lower in the severe CRF group than in the mild CRF group both before and one month after surgery. The factors identified on logistic regression analysis were the preoperative CFS score and preoperative 6MWD.

CONCLUSION

CRF occurring one month after surgery might be affected by preoperative fatigue and preoperative exercise tolerance.

Quality of Life, Fatigue, and Sleep Problems in Pancreatic Cancer Patients—A Randomized Trial on the Effects of Exercise

BACKGROUND

Improving quality of life (QoL) is an important treatment goal in pancreatic cancer patients. Although the beneficial effects of exercise on QoL are well understood, few studies have investigated more aggressive cancers such as pancreatic cancer.

METHODS

Within a randomized trial, we assessed the efficacy of 6-month resistance training on physical functioning (primary outcome) and further QoL-related outcomes. 65 pancreatic cancer patients were assigned to home-based training, supervised training, or a usual care control group. Analysis-of-covariance models on changes from baseline to 6 and 3 months were ap- plied.

RESULTS

47 patients completed the intervention period. After 6 months, no effects of resistance training were observed. However, after 3 months, explorative analyses showed significant between-group mean differences (MD) in favor for resistance training for physical functioning (pooled group: MD=11.0; p=0.016; effect size[ES]=0.31), as well as for global QoL (MD=12.1; p=0.016; effect size=0.56), and other outcomes, such as sleep problems and fatigue. Multiple imputation analyses yielded similar results. Home-based and supervised training performed similarly.

CONCLUSION

This first randomized resistance training trial in pancreatic cancer patients indicated clinically relevant improve- ments in QoL after 3 but not after 6 months. Given the severity of pancreatic cancer, exercise recommendations may already commence at surgery.

Variability and limitations in home-based exercise program descriptions in oncology: a scoping review

BACKGROUND

The literature reflects considerable heterogeneity in what constitutes home-based exercise interventions. The variability for where and what "home-based" exercise can represent challenges interpretation of findings and appropriate advocacy, referral, or development of these models of care. Therefore, the objective of this review was to provide a comprehensive summary of how home-based exercise is defined and reported in the literature and summarize the range of supportive elements utilized in home-based exercise trials.

METHODS

We followed methodology for scoping reviews. Relevant research databases were searched from inception to March 2019. Two reviewers independently screened articles to determine eligibility and extracted terminology used to describe home-based exercise and intervention details for intervention delivery.

RESULTS

Of the 9432 records identified, 229 articles met inclusion criteria. Across the literature, exercise interventions were described as home-based if they were completed at-home, outdoors in the neighbourhood, and in community facilities; or in self-selected environments; or if they were unsupervised. Supportive elements for home-based models ranged with respect to the amount of supervision and resources utilized, including the provision of print materials, exercise equipment, telephone support, home visits, and technology.

CONCLUSIONS

This review provides a comprehensive summary of strategies previously utilized to deliver home-based exercise interventions in oncology, along with the various definitions of the home-based environment for exercise reported by researchers. Specific recommendations to improve the prescription and reporting of home-based exercise interventions are provided in order to facilitate the delivery, evaluation, and translation of findings into clinical practice.

Feasibility of low-cost accelerometers in measuring functional recovery after major oncologic surgery

BACKGROUND AND OBJECTIVES

Low-cost consumer-based activity monitors (CAMs), such as the Fitbit, are popular for fitness and wellness tracking. Functional status is an excellent predictor of postoperative outcomes, yet objective measurements are resource-intensive. The aim of this study is to demonstrate the feasibility of using activity monitors during the perioperative period in patients undergoing major oncologic surgery.

METHODS

An institution review board proved that a prospective study was conducted. CAMs were worn throughout the perioperative period and accelerometer data were collected. Baseline and 21-days follow-up functional measures included short physical performance battery, Community Health Activities Model Program questionnaire, mobility assessment tool-short form, and 400 m walk.

RESULTS

A total of 19 of 22 (86%) patients who wore a CAM during the perioperative period had analyzable data. Compliance with wearing the device varied significantly: 100% preadmission, 19% in-hospital, and 82% postdischarge. Median daily steps decreased from preadmission to postdischarge (77% median reduction). Established resource-intensive measures of functional status did not perform well as measures of decreased functional status and activity when comparing baseline to 21-day postdischarge assessments.

CONCLUSIONS

Activity monitors are a feasible, low-cost measure of perioperative activity for patients undergoing major surgery, and may be useful in identifying patients vulnerable to postsurgical complications.

Experiences and supportive care needs of UK patients with pancreatic cancer: a cross-sectional questionnaire survey

OBJECTIVES

Patients diagnosed with pancreatic cancer have the poorest survival prognosis of any cancer. This survey aimed to describe their experiences of care and supportive care needs to inform future service provision.

DESIGN

Cross-sectional questionnaire survey of patients with pancreatic cancer in the UK.

SETTING

Individuals at any stage along the care pathway were recruited via five National Health Service sites in the UK, and online, from January to June 2018.

PARTICIPANTS

274 individuals completed the questionnaire (78% (215) were completed online). Approximately half of participants were diagnosed within the last year (133/274). Of 212 providing gender details, 82 were male and 130 were female. Ninety per cent (192/213) described themselves as White British.

PRIMARY OUTCOME MEASURES

Experiences of communication and information; involvement in treatment decisions; supportive care needs.

RESULTS

Communication with, and care received from, clinical staff were generally reported positively. However, 29% (75/260) of respondents did not receive enough information at diagnosis, and 10% (25/253) felt they were not involved in decisions about their treatment, but would have liked to be. Supportive care needs were greatest in psychological and physical/daily living domains. 49% (108/221) of respondents reported one or more moderate/high unmet needs within the last month, of which the most commonly reported were: dealing with uncertainty about the future; fears about the cancer spreading; not being able to do things they used to; concerns about those close to them; lack of energy; anxiety; feelings of sadness and feeling down/depressed. Experiences were poorer, and unmet supportive care needs greater, in patients with unresectable disease.

CONCLUSIONS

Patients with pancreatic cancer have unmet information and support needs across the cancer trajectory. Psychological and physical support appears to be the biggest gap in care. Needs should be assessed and supportive care interventions implemented from the point of diagnosis, and monitored regularly to help patients live as good a quality of life as possible.

Novel Strategies for Cancer Treatment: Highlights from the 55th IACR Annual Conference

While conventional cancer treatments, such as surgery, radiotherapy and chemotherapy, have been combined for decades in an effort to treat cancer patients, the emergence of novel fields of cancer research have led to a renewed interest in combining conventional treatments with more innovative approaches. The realisation that cancer progression is not exclusively due to changes in the cancer epithelial cells, but also involves changes in the tumour microenvironment, has opened new avenues for combination treatments. Here we discuss the use of combination therapies presented at the 55th Irish Association for Cancer Research (IACR) Annual Conference, highlighting examples of novel therapeutic strategies which, combined with conventional therapies, may greatly enhance not only the overall outcome for patients, but also the quality of life for cancer survivors. Among the novel treatment strategies, immune metabolism, epigenetic therapies and physical exercise are presented. In addition, novel technologies in the field of precision medicine, which will be useful to discover new therapeutics and to stratify patients for combination treatments, are also discussed.

Pancreas Cancer-Associated Weight Loss

Unintentional weight loss in patients with pancreatic cancer is highly prevalent and contributes to low therapeutic tolerance, reduced quality of life, and overall mortality. Weight loss in pancreatic cancer can be due to anorexia, malabsorption, and/or cachexia. Proper supportive care can stabilize or reverse weight loss in patients and improve outcomes. We review the literature on supportive care relevant to pancreatic cancer patients, and offer evidence-based recommendations that include expert nutritional assessment, counseling, supportive measures to ensure adequate caloric intake, pancreatic enzyme supplementation, nutritional supplement replacement, orexigenic agents, and exercise. Pancreatic Cancer Action Network-supported initiatives will spearhead the dissemination and adoption of these best supportive care practices. IMPLICATIONS FOR PRACTICE: Weight loss in pancreatic cancer patients is endemic, as 85% of pancreatic cancer patients meet the classic definition of cancer cachexia. Despite its significant prevalence and associated morbidity, there is no established approach to this disease entity. It is believed that this is due to an important knowledge gap in understanding the underlying biology and lack of optimal treatment approaches. This article reviews the literature regarding pancreas cancer-associated weight loss and establishes a new framework from which to view this complex clinical problem. An improved approach and understanding will help educate clinicians, improve clinical care, and provide more clarity for future clinical investigation.

Enhancing Patient Outcomes while Containing Costs after Complex Abdominal Operation: A Randomized Controlled Trial of the Whipple Accelerated Recovery Pathway

BACKGROUND

This study was designed to determine whether a standardized recovery pathway could reduce post-pancreaticoduodenectomy hospital length of stay to 5 days without increasing complication or readmission rates.

STUDY DESIGN

Pancreaticoduodenectomy patients (high-risk patients excluded) were enrolled in an IRB-approved, prospective, randomized controlled trial (NCT02517268) comparing a 5-day Whipple accelerated recovery pathway (WARP) with our traditional 7-day pathway (control). Whipple accelerated recovery pathway interventions included early discharge planning, shortened ICU stay, modified postoperative dietary and drain management algorithm, rigorous physical therapy with in-hospital gym visit, standardized rectal suppository administration, and close telehealth follow-up post discharge. The trial was powered to detect an increase in postoperative day 5 discharge from 10% to 30% (80% power, α = 0.05, 2-sided Fisher's exact test, target accrual: 142 patients).

RESULTS

Seventy-six patients (37 WARP, 39 control) were randomized from June 2015 to September 2017. A planned interim analysis was conducted at 50% trial accrual resulting in mandatory early stoppage, as the predefined efficacy end point was met. Demographic variables between groups were similar. The WARP significantly increased the number of patients discharged to home by postoperative day 5 compared with controls (75.7% vs 12.8%; p < 0.001) without increasing readmission rates (8.1% vs 10.3%; p = 1.0). Overall complication rates did not differ between groups (29.7% vs 43.6%; p = 0.24), but the WARP significantly reduced the time from operation to adjuvant therapy initiation (51 days vs 66 days; p = 0.005) and hospital cost ($26,563 vs $31,845; p = 0.011).

CONCLUSIONS

The WARP can safely reduce hospital length of stay, time to adjuvant therapy, and cost in selected pancreaticoduodenectomy patients without increasing readmission risk.

Progressive Resistance Training to Impact Physical Fitness and Body Weight in Pancreatic Cancer Patients: A Randomized Controlled Trial

OBJECTIVES

Maintaining or improving muscle mass and muscle strength is an important treatment goal in pancreatic cancer (PC) patients because of high risk of cachexia. Therefore, we assessed feasibility and effectivity of a 6-month progressive resistance training (RT) in PC patients within a randomized controlled trial.

METHODS

Sixty-five PC patients were randomly assigned to either supervised progressive RT (RT1), home-based RT (RT2), or usual care control group (CON). Both exercise groups performed training 2 times per week for 6 months. Muscle strength for knee, elbow, and hip extensors and flexors and cardiorespiratory fitness and body weight were assessed before and after the intervention period.

RESULTS

Of 65 patients, 43 patients were analyzed. Adherence rates were 64.1% (RT1) and 78.4% (RT2) of the prescribed training sessions. RT1 showed significant improvements in elbow flexor/extensor muscle strength and in maximal work load versus CON and RT2 (P < 0.05). Further, knee extensors were significantly improved for RT1 versus CON (P < 0.05). Body weight revealed no significant group differences over time.

CONCLUSIONS

Progressive RT was feasible in PC patients and improved muscle strength with significant results for some muscle groups. Supervised RT seemed to be more effective than home-based RT.

Precious Data: Interim Report from the Jefferson Pancreas Tumor Registry

Purpose: The Jefferson Pancreas Tumor Registry (JPTR) is a voluntary hospital-based registry of persons with pancreas and related periampullary cancers, premalignant lesions, and nonaffected family members (NAFMs). The ultimate goals of the JPTR are to provide a link between family history, gene mutations, and precision medicine therapy, and to identify high-risk NAFMs for potential surveillance screening.

Methods: The JPTR is an Institutional Review Board approved longitudinal epidemiological study housed in the Department of Surgery at Thomas Jefferson University Hospital. Individuals who met the eligibility criteria and signed informed consent provide information on hereditary conditions, family history of cancers, environmental exposures, and occupational risk factors. Data are collected using a self-administered questionnaire, the electronic medical record, and the molecular analysis of tumor specimens.

Results: Established in 2008, >725 persons have enrolled in the JPTR. The cohort is mostly composed of sporadic pancreas cancer, with 13% of enrollees having familial pancreas cancer and a control group comprising nonaffected persons. Data from the registry have been utilized to inform clinical studies, molecular investigations, and to shed light on and gain insight into the lived experience of persons with these conditions.

Conclusion: The JPTR contains precious qualitative data and is an invaluable repository of information about persons with pancreatic and related tumors.

Exercise Training in Cancer Control and Treatment

Exercise training is playing an increasing role in cancer care, as accumulating evidence demonstrates that exercise may prevent cancer, control disease progression, interact with anti-cancer therapies, and improve physical functioning and psychosocial outcomes. In this overview article, we present the current state of the field of exercise oncology, which currently comprises of nearly 700 unique exercise intervention trials with more than 50,000 cancer patients. First, we summarize the range of these interventions with regard to diagnoses, clinical setting, timing, and type of intervention. Next, we provide a detailed discussion of the 292 trials, which have delivered structured exercise programs, outlining the impact of exercise training on cancer-specific, physiological, and psychosocial outcomes in the light of the challenges and physiological limitations cancer patients may experience. In summary, the safety and feasibility of exercise training is firmly established across the cancer continuum, and a wide range of beneficial effects on psychosocial and physiological outcomes are well documented. Many of these beneficial effects are linked to the general health-promoting properties of exercise. However, it is becoming increasing evident that exercise training can have direct effects on cancer and its treatment. This calls for future exercise oncology initiatives, which aim to target cancer-specific outcomes, and which are integrated into the concurrent cancer trajectory. Here, the field must bridge extensive knowledge of integrative exercise physiology with clinical oncology and cancer biology to provide a basis of individualized targeted approaches, which may place exercise training as an integrated component of standard cancer care. © 2019 American Physiological Society.

Energy balance and gastrointestinal cancer: risk, interventions, outcomes and mechanisms

Obesity increases the risk of multiple gastrointestinal cancers and worsens disease outcomes. Conversely, strong inverse associations have emerged between physical activity and colon cancer and possibly other gastrointestinal malignancies. The effect of weight loss interventions - such as modifications of diet and/or physical activity or bariatric surgery - remains unclear in patients who are obese and have gastrointestinal cancer, although large clinical trials are underway. Human intervention studies have already shed light on potential mechanisms underlying the energy balance-cancer relationship, with preclinical models supporting emerging pathway effects. Central to interventions that reduce obesity or increase physical activity are pluripotent cancer-preventive effects (including reduced systemic and adipose tissue inflammation and angiogenesis, altered adipokine levels and improved insulin resistance) that directly interface with the hallmarks of cancer. Other mechanisms, such as DNA repair, oxidative stress and telomere length, immune function, effects on cancer stem cells and the microbiome, could also contribute to energy balance effects on gastrointestinal cancers. Although some mechanisms are well understood (for instance, systemic effects on inflammation and insulin signalling), other areas remain unclear. The current state of knowledge supports the need to better integrate mechanistic approaches with preclinical and human studies to develop effective, personalized diet and exercise interventions to reduce the burden of obesity on gastrointestinal cancer.

Engaging the older cancer patient; Patient Activation through Counseling, Exercise and Mobilization - Pancreatic, Biliary tract and Lung cancer (PACE-Mobil-PBL) - study protocol of a randomized controlled trial

Background

Several intervention studies have demonstrated that exercise training has beneficial effects among cancer patients. However, older cancer patients are underrepresented in clinical trials, and only few exercise-based studies have focused specifically on older patients with cancer. In particular, research investigating the effects of exercise training among older patients with advanced cancer is lacking. The purpose of the current study is to investigate the effect of a 12-week multimodal and exercise-based intervention among older patients (≥65 years) with advanced pancreatic, biliary tract or lung cancer, who are treated with first-line palliative chemotherapy, immunotherapy or targeted therapy.

Methods

PACE-Mobil-PBL is a two-armed randomized controlled trial. Participants will be randomized 1:1 to an intervention group (N = 50) or a control group (N = 50). Participants in the intervention group will receive standard oncological treatment and a 12-week multimodal intervention, comprised of: (I) supervised exercise training, twice weekly in the hospital setting, (II) home-based walking with step counts and goal-setting, (III) supportive and motivational nurse-led counseling, and (IV) protein supplement after each supervised training session. Participants in the control group will receive standard oncological treatment. The primary outcome is physical function measured by the 30-s chair stand test. Secondary outcomes include measures of feasibility, activity level, physical capacity and strength, symptom burden, quality of life, toxicity to treatment, dose reductions, inflammatory biomarkers, body weight and composition, hospitalizations and survival. Assessments will be conducted at baseline, and after 6, 12 and 16 weeks.

Discussion

The current study is one of the first to investigate the effect of an exercise-based intervention specifically targeting older patients with advanced cancer. PACE-Mobil-PBL supports the development of health promoting guidelines for older patients with cancer, and the study results will provide new and valuable knowledge in this understudied field.

Trial registration

The study was prospectively registered at ClinicalTrials.gov on January 26, 2018 (ID: NCT03411200).

Interventions for promoting habitual exercise in people living with and beyond cancer

BACKGROUND

This is an updated version of the original Cochrane Review published in the Cochrane Library 2013, Issue 9. Despite good evidence for the health benefits of regular exercise for people living with or beyond cancer, understanding how to promote sustainable exercise behaviour change in sedentary cancer survivors, particularly over the long term, is not as well understood. A large majority of people living with or recovering from cancer do not meet current exercise recommendations. Hence, reviewing the evidence on how to promote and sustain exercise behaviour is important for understanding the most effective strategies to ensure benefit in the patient population and identify research gaps.

OBJECTIVES

To assess the effects of interventions designed to promote exercise behaviour in sedentary people living with and beyond cancer and to address the following secondary questions: Which interventions are most effective in improving aerobic fitness and skeletal muscle strength and endurance? Which interventions are most effective in improving exercise behaviour amongst patients with different cancers? Which interventions are most likely to promote long-term (12 months or longer) exercise behaviour? What frequency of contact with exercise professionals and/or healthcare professionals is associated with increased exercise behaviour? What theoretical basis is most often associated with better behavioural outcomes? What behaviour change techniques (BCTs) are most often associated with increased exercise behaviour? What adverse effects are attributed to different exercise interventions?

SEARCH METHODS

We used standard methodological procedures expected by Cochrane. We updated our 2013 Cochrane systematic review by updating the searches of the following electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, Embase, AMED, CINAHL, PsycLIT/PsycINFO, SportDiscus and PEDro up to May 2018. We also searched the grey literature, trial registries, wrote to leading experts in the field and searched reference lists of included studies and other related recent systematic reviews.

SELECTION CRITERIA

We included only randomised controlled trials (RCTs) that compared an exercise intervention with usual care or 'waiting list' control in sedentary people over the age of 18 with a homogenous primary cancer diagnosis.

DATA COLLECTION AND ANALYSIS

In the update, review authors independently screened all titles and abstracts to identify studies that might meet the inclusion criteria, or that could not be safely excluded without assessment of the full text (e.g. when no abstract is available). We extracted data from all eligible papers with at least two members of the author team working independently (RT, LS and RG). We coded BCTs according to the CALO-RE taxonomy. Risk of bias was assessed using the Cochrane's tool for assessing risk of bias. When possible, and if appropriate, we performed a fixed-effect meta-analysis of study outcomes. If statistical heterogeneity was noted, a meta-analysis was performed using a random-effects model. For continuous outcomes (e.g. cardiorespiratory fitness), we extracted the final value, the standard deviation (SD) of the outcome of interest and the number of participants assessed at follow-up in each treatment arm, to estimate the standardised mean difference (SMD) between treatment arms. SMD was used, as investigators used heterogeneous methods to assess individual outcomes. If a meta-analysis was not possible or was not appropriate, we narratively synthesised studies. The quality of the evidence was assessed using the GRADE approach with the GRADE profiler.

MAIN RESULTS

We included 23 studies in this review, involving a total of 1372 participants (an addition of 10 studies, 724 participants from the original review); 227 full texts were screened in the update and 377 full texts were screened in the original review leaving 35 publications from a total of 23 unique studies included in the review. We planned to include all cancers, but only studies involving breast, prostate, colorectal and lung cancer met the inclusion criteria. Thirteen studies incorporated a target level of exercise that could meet current recommendations for moderate-intensity aerobic exercise (i.e.150 minutes per week); or resistance exercise (i.e. strength training exercises at least two days per week).Adherence to exercise interventions, which is crucial for understanding treatment dose, is still reported inconsistently. Eight studies reported intervention adherence of 75% or greater to an exercise prescription that met current guidelines. These studies all included a component of supervision: in our analysis of BCTs we designated these studies as 'Tier 1 trials'. Six studies reported intervention adherence of 75% or greater to an aerobic exercise goal that was less than the current guideline recommendations: in our analysis of BCTs we designated these studies as 'Tier 2 trials.' A hierarchy of BCTs was developed for Tier 1 and Tier 2 trials, with programme goal setting, setting of graded tasks and instruction of how to perform behaviour being amongst the most frequent BCTs. Despite the uncertainty surrounding adherence in some of the included studies, interventions resulted in improvements in aerobic exercise tolerance at eight to 12 weeks (SMD 0.54, 95% CI 0.37 to 0.70; 604 participants, 10 studies; low-quality evidence) versus usual care. At six months, aerobic exercise tolerance was also improved (SMD 0.56, 95% CI 0.39 to 0.72; 591 participants; 7 studies; low-quality evidence).

AUTHORS' CONCLUSIONS

Since the last version of this review, none of the new relevant studies have provided additional information to change the conclusions. We have found some improved understanding of how to encourage previously inactive cancer survivors to achieve international physical activity guidelines. Goal setting, setting of graded tasks and instruction of how to perform behaviour, feature in interventions that meet recommendations targets and report adherence of 75% or more. However, long-term follow-up data are still limited, and the majority of studies are in white women with breast cancer. There are still a considerable number of published studies with numerous and varied issues related to high risk of bias and poor reporting standards. Additionally, the meta-analyses were often graded as consisting of low- to very low-certainty evidence. A very small number of serious adverse effects were reported amongst the studies, providing reassurance exercise is safe for this population.

Health-Related Quality of Life: The Impact on Morbidity and Mortality

In the age of ever-expanding treatments and precision medicine, the hope for cure remains the ultimate goal for patients and providers. Equally important to many patients is the quality of life achieved during and after treatment. Evidence suggests that overall quality of life is important to patients and plays a role in determining outcomes in patients with cancer. This article examines components of health-related quality of life and cancer treatment, including physical, psychosocial, and financial burden, as well as how these components affect patients' overall wellbeing and survival.

Symptom Clusters in Patients With Pancreatic Cancer Undergoing Surgical Resection: Part II

OBJECTIVES

To explore the relationship between 16 symptom clusters (SCs), clinical and demographic influencing factors, and clinical outcomes over time in patients with pancreatic cancer (PC) undergoing surgical resection.

SAMPLE & SETTING

143 patients with stage II PC undergoing surgical resection were recruited to participate in this longitudinal, exploratory study conducted at Thomas Jefferson University Hospital, a National Cancer Institute-designated cancer center.

METHODS & VARIABLES

Quality of life was measured preoperatively and at three, six, and nine months postoperatively. Statistical methods included simple linear and Cox proportional hazard regression.

RESULTS

Preoperative pain was significantly associated with the pain-gastrointestinal SC, and preoperative worry was significantly associated with the mood SC. The strongest negative association with emotional well-being across all study time points was found with the preoperative mood SC. The insomnia-digestive problems SC and the nutritional problems SC demonstrated a trend toward poor survival.

IMPLICATIONS FOR NURSING

Findings provide evidence that preoperative worry and pain are associated with SC severity and that SCs may have a detrimental effect on quality of life and survival in patients with PC undergoing surgical resection.

Symptom Clusters in Patients With Pancreatic Cancer Undergoing Surgical Resection: Part I

OBJECTIVES

To describe patient-reported symptoms and symptom clusters in patients with pancreatic cancer (PC) undergoing surgical resection.

SAMPLE & SETTING

143 patients with stage II PC undergoing surgical resection alone or with subsequent adjuvant chemoradiation or chemotherapy were recruited to participate in a nested, longitudinal, exploratory study through convenience sampling techniques from Thomas Jefferson University Hospital, a National Cancer Institute-designated cancer center.

METHODS & VARIABLES

The Functional Assessment in Cancer Therapy-Hepatobiliary questionnaire was used to assess 17 PC symptoms preoperatively and at three, six, and nine months postoperatively. Exploratory and confirmatory factor analyses were used to identify symptom clusters.

RESULTS

Fatigue, trouble sleeping, poor appetite, trouble digesting food, and weight loss were consistently reported as the most prevalent and severe symptoms. Sixteen distinct symptom clusters were identified within nine months of surgery. Four core symptom clusters persisted over time.

IMPLICATIONS FOR NURSING

Findings may be used to provide anticipatory patient and family guidance and to inform clinical assessments of symptoms and symptom clusters in this population.

Anthropometric Changes in Patients with Pancreatic Cancer Undergoing Preoperative Therapy and Pancreatoduodenectomy

BACKGROUND

The changes in body composition that occur in response to therapy for localized pancreatic ductal adenocarcinoma (PDAC) and during the early survivorship period, as well as their clinical significance, are poorly understood.

METHODS

One hundred twenty-seven consecutive patients with PDAC who received preoperative therapy followed by pancreatoduodenectomy (PD) at a single institution between 2009 and 2012 were longitudinally evaluated. Changes in skeletal muscle (SKM), visceral adipose tissue (VAT), and subcutaneous adipose tissue (SAT) were measured on serial computed tomography images obtained upon presentation, prior to pancreatectomy, and approximately 3 and 12 months after surgery.

RESULTS

Prior to therapy, patients' mean baseline BMI was 26.5 ± 4.7 kg/m² and 63.0% met radiographic criteria for sarcopenia. During a mean 5.4 ± 2.3 months of preoperative therapy, minimal changes in SKM (- 0.5 ± 7.8%, p > 0.05), VAT (- 1.8 ± 62.6%, p < 0.001), and SAT (- 4.8 ± 27.7%, p < 0.001) were observed. In contrast, clinically significant changes were observed on postoperative CT compared to baseline anthropometry: SKM - 4.1 ± 10.7%, VAT - 38.7 ± 30.2%, and SAT - 24.1 ± 22.6% (all p < 0.001) and these changes persisted at one year following PD. While anthropometric changes during preoperative therapy were not independently associated with survival, SKM gain between the postoperative period and one-year follow-up was associated with improved overall survival (OR 0.50, 95% CI 0.29-0.87).

CONCLUSIONS

In contrast to the minor changes that occur during preoperative therapy for PDAC, significant losses in key anthropometric parameters tend to occur over the first year following PD. Ongoing SKM loss in the postoperative period may represent an early marker for worse outcomes.
