Effect of metformin on incidence, recurrence, and mortality in prostate cancer patients: integrating evidence from real-world studies

PURPOSE

Metformin has been suggested to reduce the risk of cancer. However, previous studies have been inconsistent regarding the relationship between metformin use and the risk of occurrence of prostate cancer (PCa). The purpose of this study was to assess the effect of metformin on clinical outcomes in patients with PCa in a meta-analysis and to explore the possible dose-response relationship.

METHODS

A systematic literature search was conducted in 10 electronic databases and 4 registries. The combined relative risks (RRs) were calculated using a random-effects model with 95% confidence interval (CIs) to assess the effect of metformin on the risk of PCa. Relevant subgroup analyses and sensitivity analyses were performed.

RESULTS

The across studies results show that metformin use associated with lower incidence of PCa (RR: 0.82, 95% CI: 0.74-0.91). Metformin use was also found to reduce PCa recurrence, but the results were not statistically significant (RR: 0.97, 95% CI: 0.81-1.15). Metformin use was not associated with PCa mortality (RR: 0.94, 95% CI: 0.81-1.09). The results of subgroup analyses indicated that the type of study was a cohort study and the population came from both Asia and Europe showed that taking metformin reduced the incidence of PCa. A linear correlation was found between the duration of metformin use and its protective effect.

CONCLUSIONS

This meta-analysis revealed an independent correlation between metformin use and reduced incidence of PCa. Metformin use was not associated with either PCa recurrence rate or mortality. Furthermore, the effect of metformin on PCa incidence was found to be related to duration.

Gastric Cancer Survivorship: Multidisciplinary Management, Best Practices and Opportunities

PURPOSE

Gastric cancer is the 5th most common malignancy worldwide. As early detection increases and treatments for gastric cancer improve, the number of gastric cancer survivors grows.

METHODS

Here, we review the diagnosis and management of gastric cancer and discuss important considerations for gastric cancer survivorship including cancer surveillance, weight loss, malnutrition, fatigue, specific complications related to surgery and radiation, quality of life in gastric cancer survivorship, health behavior, and models of survivorship.

RESULTS

Multimodality therapy with chemotherapy and surgery can result in chronic toxicities in multiple organ systems. This emphasizes the need for a multidisciplinary survivorship care model including cancer surveillance, management of chronic toxicities, and optimization of modifiable risk factors with long-term involvement of appropriate providers.

CONCLUSION

Adequately caring for gastric cancer survivors requires a coordinated, multidisciplinary approach.

Multidimensional Model of Energy in Patients With Cancer

OBJECTIVES

Evidence suggests that energy is a distinct symptom from fatigue in patients with cancer. The purpose of this paper is to present the Multidimensional Model of Energy in Patients with Cancer (MMEPC) that is based on emerging evidence and to make recommendations for clinical practice and future research.

METHODS

The literature was reviewed to determine various factors associated with variations in energy in patients with cancer. In addition, some of the emerging evidence in the model is supported by studies of energy in the general population and in patients with other chronic conditions.

RESULTS

Based on a review of the literature, specific concepts in the MMEPC include: person factors, clinical factors, cancer-related factors, biological factors, factors associated with energy balance, and co-occurring symptoms. The evidence to support the association between each of these factors and variations in energy levels in patients with cancer is described and synthesized.

CONCLUSION

This article provides emerging evidence on factors that influence variations in energy levels in patients with cancer. While the fundamental biobehavioral and biologic mechanisms that underlie variations in energy levels are not well understood, the model can be used to design pre-clinical and clinical studies of energy in patients with cancer. In addition, while emerging evidence supports the hypothesis that fatigue and energy are distinct symptoms, additional research on common and distinct risk factors and underlying mechanisms is warranted to be able to develop and test precision interventions for one or both symptoms.

IMPLICATIONS FOR NURSING PRACTICE

The risk factors (eg, being female, sleep quality) associated with variations in energy levels in patients with cancer identified in this paper have important clinical implications. Clinicians can use the identified risk factors to guide their assessments; identify high-risk patients with decrements in energy decrement; and develop targeted energy conservation interventions for the patients.

Mediterranean-style dietary interventions in adults with cancer: a systematic review of the methodological approaches, feasibility, and preliminary efficacy

BACKGROUND

Cancer and its treatments can lead to excess body fat, decreases in lean mass, cardiotoxicity, and other side effects. The Mediterranean diet (MED-diet) has the potential to improve clinical and supportive care outcomes. The aim of this systematic review was to evaluate the feasibility, safety, and efficacy of the MED-diet on health outcomes in adults with cancer.

METHODS

Three databases were searched from inception to February 2023. Eligible studies included randomised controlled trials testing a MED-diet intervention among adults with cancer. Within- and between-group differences for adherence, dietary intake and health outcomes were extracted.

RESULTS

Fifteen studies describing fourteen interventions were included, and there were considerable differences in study design and implementation of the MED-diet. Studies were predominately in women with a history of breast cancer. The MED-diet was safe with no adverse events reported, and feasible with high adherence and/or increases in MED-diet-compliant foods. The MED-diet when applied with an energy restriction below estimated requirements for weight loss demonstrated reductions in body weight (range: -3.9 kg to -0.7 kg). Interventions that showed significant reductions in body weight also improved quality of life. There is limited evidence to evaluating the MED-diet on cardiovascular and inflammatory markers, and heterogenous MED-diet prescriptions impede definitive conclusions on these health outcomes.

CONCLUSION

The MED-diet was feasible and safe for adults with cancer. There were reported benefits for weight loss following a MED-diet when an energy restriction was applied, however further evaluation to determine the effects on cardiometabolic biomarkers and other outcomes are required.

The Influence of Exercise on Cancer Risk, the Tumor Microenvironment and the Treatment of Cancer

There are several modifiable factors that can be targeted to prevent and manage the occurrence and progression of cancer, and maintaining adequate exercise is a crucial one. Regular physical exercise has been shown to be a beneficial strategy in preventing cancer, potentially amplifying the effectiveness of established cancer therapies, alleviating certain cancer-related symptoms, and possibly mitigating side effects resulting from treatment. Nevertheless, the exact mechanisms by which exercise affects tumors, especially its impact on the tumor microenvironment (TME), remain uncertain. This review aims to present an overview of the beneficial effects of exercise in the context of cancer management, followed by a summary of the exercise parameters, especially exercise intensity, that need to be considered when prescribing exercise for cancer patients. Finally, we discuss the influence of exercise on the TME, including its effects on crucial immune cells (e.g., T cells, macrophages, neutrophils, natural killer cells, myeloid-derived suppressor cells, B cells), intratumor angiogenesis, and cancer metabolism. This comprehensive review provides up-to-date scientific evidence on the effects of exercise training on cancer and offers guidance to clinicians for the development of safe and feasible exercise training programs for cancer patients in clinical practice.

Effectiveness of dietetic care for cancer survivors in the primary care setting: A systematic review and meta-analysis of randomized controlled trials

PURPOSE

Nutrition plays an important role in cancer survivorship. This systematic review and meta-analysis aim to critically assess and quantify the effectiveness of nutrition care interventions provided by dietitians to survivors who have completed treatment for cancer.

METHODS

A systematic review of randomized controlled trials (RCTs) published from January 2004 to November 2023 reporting the effectiveness of primary care dietetic interventions with adult cancer survivors was conducted. PubMed, Scopus, CINAHL, Embase, ProQuest and PsycINFO databases were searched for key terms. Meta-analyses were conducted where there were sufficient studies of the same cancer type and outcomes.

RESULTS

Twelve RCTs representing 1138 cancer survivors (519 breast cancer; 75 prostate cancer; 544 colorectal cancer) were included. Primary outcome measures included weight loss (n = 6), quality of life (n = 2), reducing lymphedema-related arm volume (n = 2), nutritional status (n = 1) and increasing fruit and vegetable intake (n = 1). Weight loss was observed in studies where this was the primary outcome. Results for quality of life varied. Meta-analyses of RCTs with breast cancer survivors showed that dietitian intervention achieved a mean of 3.7 kg greater intentional weight loss and 2.3% greater body fat decrease than control (p < 0.0001).

CONCLUSIONS

This study provides evidence for the effectiveness of primary care dietetic interventions by dietitians with cancer survivors, particularly with respect to intentional weight and fat loss in breast cancer survivors.

IMPLICATIONS FOR CANCER SURVIVORS

Dietitians can play a key role in managing weight and improving long term health outcomes and prognosis for cancer survivors beyond the acute care setting.

Fatigue in Prostate Cancer: A Roundtable Discussion and Thematic Literature Review

Context

Cancer and its treatments cause fatigue in up to 90% of men with advanced prostate cancer. As men with prostate cancer are surviving longer, cancer-related fatigue is becoming increasingly important for clinicians to understand and proactively manage.

Objective

The aim of this work is to identify knowledge gaps that may support healthcare professionals to recommend personalised fatigue management strategies.

Evidence acquisition

This manuscript is based on a roundtable discussion held during the European Association of Urology 2022 Annual Symposium, combined with a review of the literature. Five core themes were generated from the roundtable: (1) meaning of fatigue in prostate cancer patients, (2) impact of fatigue, (3) association between fatigue and treatment selection, (4) benefits of managing fatigue, and (5) barriers to exercise.

Evidence synthesis

Cancer-related fatigue has complex underlying aetiology and is a subjective experience that may be under-reported. Some studies have shown that techniques such as education, cognitive behavioural therapy, guided imagery, and progressive muscle relaxation can result in clinically meaningful improvements in fatigue. However, the largest body of evidence, and a theme echoed in the roundtable discussions, was the benefit of exercise on fatigue. Despite the benefits of exercise, for some men, objective barriers to exercise exist and knowledge of benefits does not automatically translate into implementation and adherence.

Conclusions

Understanding the specific health needs of individual patients and their desired health outcomes is essential to identify personalised strategies for minimising fatigue. As an outcome of the roundtable meeting, we developed a quick reference guide for healthcare providers. A high-resolution copy can be downloaded from https://patients.uroweb.org/library/fatigue-in-prostate-cancer-patients-guide/.

Patient summary

This article is based on dialogue between a group of specialists, patients, and caregivers, which took place at a roundtable meeting during the European Association of Urology 2022 Annual Symposium. The group discussed how healthcare providers can best support their patients who experience fatigue. The group subsequently developed a guide to help healthcare providers during appointments.

Psychosocial Factors Associated with Cognitive Function in Prostate Cancer Survivors on Hormonal Treatments: A Systematic Review

Hormonal treatments (HT) for prostate cancer (e.g., androgen deprivation therapy) yield clinical and survival benefits, yet adverse cognitive changes may be a side effect. Since psychosocial factors are largely modifiable, interventions targeting these factors may help mitigate these adverse cognitive effects. This systematic review aimed to identify a range of psychosocial factors associated with cognitive function in individuals with prostate cancer undergoing HT and to determine whether these factors mitigate or exacerbate this effect. Applying PRISMA guidelines, a comprehensive search of relevant databases conducted in September 2023 using terms related to prostate cancer, hormone therapy, and cognitive outcomes was undertaken. The search yielded 694 unique abstracts, with 11 studies included for analysis examining the relationship between cognitive function and the following psychosocial factors: psychological distress, fatigue, insomnia, and coping processes. Findings were mixed with only two studies reporting significant associations between cognitive performance with fatigue and depression. Three studies that included measures of perceived cognitive function identified associations with depression, anxiety, fatigue, insomnia, illness threat appraisals, and coping styles. However, no studies found evidence for an association between self-reported and objective measures of cognitive functioning. Evidence regarding the association of interpersonal factors is lacking. Moreover, whether these factors mitigate or exacerbate the effect of HT on cognitive function still needs to be determined. Overall, the research exploring the association between psychosocial factors and cognitive function in prostate cancer survivors undergoing HT is still in its infancy. Further research is required to optimize the implementation of neuropsychological interventions for prostate cancer survivors.

Case studies on psychosocial factors that help make exercise programmes for prostate cancer patients self-sustaining

OBJECTIVES

Patients with prostate cancer (PCa) benefit from regular exercise, but it is difficult for patients to maintain an exercise regime. We examined two exercise programmes that have proven to be self-sustaining with the goal of identifying features they share that may contribute to their success.

METHODS

We compared the FC Prostata football (soccer) league in Denmark and the 'Butts in a Boat' (BIAB) dragon-boating team in Canada. The FC Prostata Project Coordinator and the BIAB team leaders provided information on their programmes' history and structure.

RESULTS

Both programmes are team-based with regularly scheduled intense exercise at their core. In both cases, social activities evolved spontaneously, starting with the men going out for food and/or drinks after practices. The sustainability of these programmes may be driven by the regular socialisation linked to the fitness activities.

CONCLUSIONS

Our case studies suggest that exercise programmes for PCa patients may have a good chance of being self-sustaining, if they are: (1) centred around intense exercise, (2) of a team nature, (3) structured to promote egalitarianism and avoid one-on-one competition within teams, yet (4) have some competitions between teams. The data suggest that informal social activities organised by patients after team practices may be important for building fellowship and strengthening patients' commitment to exercise both for themselves and for their team members.

The effect of exercise interventions on quality of life in patients with multiple myeloma: a systematic review and meta-analysis of randomised controlled trials

PURPOSE

To determine the effect of exercise interventions on quality of life in adults with multiple myeloma.

METHODS

A literature search of 10 sources was performed in June 2022 to identify eligible studies for synthesis.

INCLUSION CRITERIA

randomised controlled trials comparing the effect of exercise interventions with usual care in adults with a diagnosis of multiple myeloma. The risk of bias was assessed using the Revised Cochrane risk-of-bias tool for randomized trials. Meta-analysis was performed using a random-effects model with inverse variance and 95% confidence intervals. Forest plots were constructed to present pooled data.

RESULTS

Five RCTs, which included a total of 519 participants, were selected for inclusion. Four of the five studies were included in the meta-analysis. The mean participant age ranged from 55 to 67 years old. All studies included an aerobic exercise component. Intervention length ranged from 6 to 30 weeks. Meta-analysis of 118 participants showed that exercise interventions had no impact on global quality of life (MD = 2.15, 95% CI: - 4.67, 8.97, p = 0.54, I2 = 0%). Exercise interventions negatively impacted participant grip strength (MD: - 3.69, 95% CI: - 7.12, -0.26, p = 0.03, I2 = 0%) according to pooled data from 186 participants.

CONCLUSION

Exercise interventions have no positive impact on the quality of life of patients with multiple myeloma. The analysis is limited by a high risk of bias across included studies and low certainty evidence. Further high-quality trials are needed to assess the role of exercise in patients with multiple myeloma.

The Current Trend of Radiation Therapy for Patients with Localized Prostate Cancer

A recent approach to radiotherapy for prostate cancer is the administration of high doses of radiation to the prostate while minimizing the risk of side effects. Thus, image-guided radiotherapy utilizes advanced imaging techniques and is a feasible strategy for increasing the radiation dose. New radioactive particles are another approach to achieving high doses and safe procedures. Prostate brachytherapy is currently considered as a combination therapy. Spacers are useful to protect adjacent organs, specifically the rectum, from excessive radiation exposure.

Two Older Hematological Malignancy Patients for Whom Nutrition Rehabilitation Was Effective Against Global Leadership Initiative on Malnutrition-Defined Malnutrition and Sarcopenia

The long-term survival rate of hematological malignancy patients with Global Leadership Initiative on Malnutrition (GLIM)-defined malnutrition and sarcopenia is poor, but nutritional rehabilitation effects in such patients are unknown. Here, two cases of older hematological malignancy patients in whom nutritional rehabilitation was effective against GLIM-defined malnutrition and sarcopenia are reported. By undergoing nutritional rehabilitation, the myeloma patient increased her six-meter walking speed and her maintained body mass index (BMI), appendicular skeletal muscle mass (ASM), and hand grip strength, whereas the Hodgkin lymphoma patient regained his hand grip strength and maintained his BMI, ASM, and six-meter walking speed.

Engaging Men of Diverse Racial and Ethnic Groups With Advanced Prostate Cancer in the Design of an mHealth Diet and Exercise Intervention: Focus Group Study

BACKGROUND

Healthy diet and exercise can improve quality of life and prognosis among men with prostate cancer. Understanding the perceived barriers to lifestyle change and patient preferences in a diverse cohort of men with prostate cancer is necessary to inform mobile health (mHealth) lifestyle interventions and increase health equity.

OBJECTIVE

We conducted a multisite study to understand the preferences, attitudes, and health behaviors related to diet and lifestyle in this patient population. This report focuses on the qualitative findings from 4 web-based focus groups comprising a racially and ethnically diverse group of patients with advanced prostate cancer who are on androgen deprivation therapy.

METHODS

We used grounded theory analyses including open, axial, and selective coding to generate codes. Qualitative data were analyzed as a whole rather than by focus group to optimize data saturation and the transferability of results. We present codes and themes that emerged for lifestyle intervention design and provide recommendations and considerations for future mHealth intervention studies.

RESULTS

Overall, 14 men participated in 4 racially and ethnically concordant focus groups (African American or Black: 3/14, 21%; Asian American: 3/14, 21%; Hispanic or Latino: 3/14, 21%; and White: 5/14, 36%). Analyses converged on 7 interwoven categories: context (home environment, access, competing priorities, and lifestyle programs), motivation (accountability, discordance, feeling supported, fear, and temptation), preparedness (health literacy, technological literacy, technological preferences, trust, readiness to change, identity, adaptability, and clinical characteristics), data-driven design (education, psychosocial factors, and quality of life), program mechanics (communication, materials, customization, and being holistic), habits (eg, dietary habits), and intervention impressions. These results suggest actionable pathways to increase program intuitiveness. Recommendations for future mHealth intervention design and implementation include but are not limited to assessment at the individual, household, and neighborhood levels to support a tailored intervention; prioritization of information to disseminate based on individuals' major concerns and the delivery of information based on health and technological literacy and communication preferences; prescribing a personalized intervention based on individuals' baseline responses, home and neighborhood environment, and support network; and incorporating strategies to foster engagement (eg, responsive and relevant feedback systems) to aid participant decision-making and behavior change.

CONCLUSIONS

Assessing a patient's social context, motivation, and preparedness is necessary when tailoring a program to each patient's needs in all racial and ethnic groups. Addressing the patients' contexts and motivation and preparedness related to diet and exercise including the household, access (to food and exercise), competing priorities, health and technological literacy, readiness to change, and clinical characteristics will help to customize the intervention to the participant. These data support a tailored approach leveraging the identified components and their interrelationships to ensure that mHealth lifestyle interventions will engage and be effective in racially and ethnically diverse patients with cancer.

Anti-fatigue Effect of Traditional Chinese Medicines: A Review

A third of the world's population suffers from unexplained fatigue, hugely impacting work learning, efficiency, and health. The fatigue development may be a concomitant state of a disease or the side effect of a drug, or muscle fatigue induced by intense exercise. However, there are no authoritative guides or clinical medication recommendations for various fatigue classifications. Traditional Chinese medicines (TCM) are used as dietary supplements or healthcare products with specific anti-fatigue effects. Thus, TCM may be a potential treatment for fatigue. In this review, we outline the pathogenesis of fatigue, awareness of fatigue in Chinese and western medicine, pharmacodynamics mechanism, and substances. Additionally, we offer a comprehensive summary of fatigue and forecast the potential effect of novel herbal-based medicines against fatigue.

Effectiveness of exercise interventions in the management of cancer-related fatigue: a systematic review of systematic reviews

BACKGROUND

Cancer-related fatigue is a widely prevalent global public health concern with serious consequences. Increasing evidence suggests the effectiveness of exercise intervention in treating cancer-related fatigue, but there is a lack of a summary of relevant literature on the same to help reach a clear consensus.

OBJECTIVE

To summarize evidence regarding the efficacy of exercise interventions to reduce cancer fatigue, as determined in systematic reviews (SRs) and/or meta-analyses (MAs).

METHOD

From inception to September 2022, PubMed (1948-2022), Embase (1974-2022), Cochrane Library (1993-2022), CINAHL (1937-2022), Web of Science (1997-2022), China Knowledge Resource Integrated Database (1999-2022), Wanfang Database (1993-2022), and Chinese Biomedical Database (1994-2022) were searched for inclusion to the study. Two reviewers independently extracted the data from the included articles. AMSTAR II was to evaluate the methodological quality of the reviews.

RESULTS

A total of 46 systematic reviews were assessed for data on exercise intervention in reducing cancer-related fatigue among cancer patients. In addition, some studies have reported adverse events during the exercise intervention period. The quality of the included systematic review was found to be low or critically low.

CONCLUSIONS

The present systematic review of systematic reviews supports exercise intervention for reducing cancer-related fatigue. Further higher-quality studies are warranted to improve the level of evidence for exercise interventions for application in the treatment of cancer-related fatigue.

Effects of a Plant-Based High-Protein Diet on Fatigue in Breast Cancer Patients Undergoing Adjuvant Chemotherapy - a Randomized Controlled Trial

BACKGROUND

Breast cancer patients undergoing chemotherapy (CT) experience fatigue and other side-effects. Studies exploring interventions with a plant-based, high-protein diet on fatigue and body composition are lacking. The effects of these interventions on fatigue, body mass index (BMI), and body composition were evaluated.

METHOD

Newly diagnosed breast cancer patients who were scheduled for adjuvant CT (n = 103) were randomly assigned to the intervention or control group. Study outcomes included fatigue using fatigue symptom inventory and body composition using bioelectric impedance analyzer done at the start of CT, 3rd CT, and 3 weeks after CT. Linear mixed models were used to compare groups over time.

RESULTS

Fatigue decreased from 57% to 28% in the intervention group and increased from 65% to 78% in the control group (p < 0.001). BMI decreased by 0.7 ± 0.8 kg/m2 in the intervention group, while the decrease was 0.4 ± 1.3 kg/m2 in the control group (p = 0.015). Fat mass decreased in the intervention group (p < 0.001) and muscle mass improved in the intervention group and decreased in the control group (p < 0.05).

CONCLUSIONS

A plant-based, high-protein diet during CT resulted in positive changes in fatigue, BMI and body composition.

What information can we gain from the quality appraisal of guidelines with physical activity recommendations for cancer patients?A systematic review using the AGREE II and AGREE-REX tools

PURPOSE

There has been growing amount of evidence supporting the benefits of physical activity (PA) on oncological patients' cancer-related health outcomes. Although guidelines on cancer rehabilitation are widely available, the varying quality and practical applicability limited the clinical application of PA recommendations. To assist the future development of guidelines, in this systematic review, we evaluated the quality and applicability of current cancer rehabilitation guidelines with PA recommendations and synthesized PA recommendations for the oncological population.

METHODS

A systematic search was conducted in PubMed, CINAHL, PEDro, EMBASE, and guideline repositories to identify guidelines with PA recommendations for cancer patients from 1 May 2016 to 1 June 2022. The quality of included guidelines was appraised using the tools "Appraisal of Guidelines for Research and Evaluation II" (AGREE II) and AGREE-REX (Recommendation Excellence). PA recommendations were synthesized from the guidelines.

RESULTS

Sixteen guidelines were extracted. The AGREE II domain "clarity of presentation" obtained the highest score, while "applicability" received the lowest, ranging from 33.33% to 98.58%. The AGREE-REX domains "values and preferences" and "implementability" generally scored lower and ranged from 45.83% to 74.17% and 55% to 88.33%, respectively. Eight high-quality guidelines were identified, and the included PA recommendations were extracted.

CONCLUSION

There were some disparities in the quality of the included guidelines. Methodological weaknesses were commonly observed in domains "applicability," "values and preferences," and "implementability"; particular attention should be given to these domains when developing future guidelines. Furthermore, this analysis indicated that more rigorous, high-quality studies are needed to generate evidence for supporting PA recommendations and provide guidance on research gaps in the field of cancer rehabilitation.

Health-related quality of life with enzalutamide versus flutamide in castration-resistant prostate cancer from the AFTERCAB study

Background

Patient-reported outcome (PRO) measures can provide valuable information in evaluating patients’ health-related quality of life (HRQoL). Post hoc analysis of the AFTERCAB study was conducted to evaluate the HRQoL benefit of enzalutamide plus androgen deprivation therapy (ADT) compared to flutamide plus ADT for the treatment of patients with castration-resistant prostate cancer (CRPC) in Japan.

Methods

The open-label AFTERCAB study was conducted from November 2016 to March 2020 in Japanese men aged ≥ 20 years with asymptomatic or mildly symptomatic CRPC. Patients received enzalutamide plus ADT or flutamide plus ADT, respectively, as first-line alternative androgen therapy (AAT). HRQoL was analyzed through the Functional Assessment of Cancer Therapy–Prostate, EuroQoL 5-Dimension 5-Level instruments, Brief Pain Inventory–Short Form, and Brief Fatigue Inventory. The longitudinal changes in HRQoL, HRQoL deterioration based on minimally important difference (MID), and time to HRQoL deterioration were evaluated for first-line AAT.

Results

Overall, HRQoL between the enzalutamide and flutamide groups was similar during first-line treatment. No statistically significant HRQoL difference in change from baseline to week 61 (least square mean difference; p value) was observed. Furthermore, proportions of pain progression, symptom worsening, and HRQoL deterioration based on MID, were not significantly different between groups.

Conclusions

The results were similar in all subscales of each PRO, demonstrating similar HRQoL deterioration based on MID criteria between the enzalutamide and flutamide groups.

Life style and interaction with microbiota in prostate cancer patients undergoing radiotherapy: study protocol for a randomized controlled trial

Background

Prostate cancer (PCa) is the second most common cancer in men worldwide. The standard non-surgical approach for localized PCa is radiotherapy (RT), but one of the limitations of high-dose RT is the potential increase in gastrointestinal and genitourinary toxicities. We present the protocol of the Microstyle study, a multicentre randomized two-arm crossover clinical trial. The primary outcome will be assessed at the end of 6-month intervention, by measuring the change in adherence to a healthy lifestyle score. The hypothesis is that modifying lifestyle we change microbiome and improve quality of life and decrease side effects of RT.

Methods

Study participants will be recruited among men undergoing RT in two Italian centers (Milan and Naples). We foresee to randomize 300 patients in two intervention arms: Intervention Group (IG) and Control Group (CG). Participants allocated to the IG will meet a dietitian and a physiotherapist before RT to receive personalized diet and exercise recommendations, according to their health status, to improve overall lifestyle and reduce side effects (bowel and/or urinary problems). Dietitian and physiotherapist will work together to set individualized goals to reduce or eliminate side effects and pain according to their health status. All participants (IG) will be given a pedometer device (steps counter) in order to monitor and to spur participants to increase physical activity and reduce sedentary behavior. Participants included in the CG will receive baseline general advice and materials available for patients undergoing RT. According to the cross-over design, the CG will cross to the intervention approach after 6-month, to actively enhance compliance towards suggested lifestyle recommendations for all patients.

Discussion

This trial is innovative in its design because we propose a lifestyle intervention during RT, that includes both dietary and physical activity counselling, as well as monitoring changes in microbiome and serum biomarkers. The promotion of healthy behaviour will be initiated before initiation of standard care, to achieve long lasting effects, controlling side effects, coping with feelings of anxiety and depression and improve efficacy of RT.

Muscle-to-tumor crosstalk: The effect of exercise-induced myokine on cancer progression

Physical exercise has gradually become a focus in cancer treatment due to its pronounced role in reducing cancer risk, enhancing therapeutic efficacy, and improving prognosis. In recent decades, skeletal muscles have been considered endocrine organs, exerting their biological functions via the endocrine, autocrine, and paracrine systems by secreting various types of myokines. The amount of myokines secreted varies depending on the intensity, type, and duration of exercise. Recent studies have shown that muscle-derived myokines are highly involved the effects of exercise on cancer. Multiple myokines, such as interleukin-6 (IL-6), oncostatin M (OSM), secreted protein acidic and rich in cysteine (SPARC), and irisin, directly mediate cancer progression by influencing the proliferation, apoptosis, stemness, drug resistance, metabolic reprogramming, and epithelial-mesenchymal transformation (EMT) of cancer cells. In addition, IL-6, interleukin-8 (IL-8), interleukin-15 (IL-15), brain-derived neurotrophic factor (BDNF), and irisin can improve obesity-induced inflammation by stimulating lipolysis of adipose tissues, promoting glucose uptake, and accelerating the browning of white fat. Furthermore, some myokines could regulate the tumor microenvironment, such as angiogenesis and the immune microenvironment. Cancer cachexia occurs in up to 80% of cancer patients and is responsible for 22%-30% of patient deaths. It is characterized by systemic inflammation and decreased muscle mass. Exercise-induced myokine production is important in regulating cancer cachexia. This review summarizes the roles and underlying mechanisms of myokines, such as IL-6, myostatin, IL-15, irisin, fibroblast growth factor 21 (FGF21) and musclin, in cancer cachexia. Through comprehensive analysis, we conclude that myokines are potential targets for inhibiting cancer progression and the associated cachexia.

Mediterranean Style Dietary Pattern with High Intensity Interval Training in Men with Prostate Cancer Treated with Androgen Deprivation Therapy: A Pilot Randomised Control Trial

Background: Androgen deprivation therapy (ADT) in prostate cancer has been shown to deteriorate body composition (reduced lean mass and increased body and fat mass) and increase the risk of cardiovascular morbidity. The Mediterranean style dietary pattern (MED-diet) and high intensity interval training (HIIT) may synergistically alleviate these side effects and improve quality of life in men treated with ADT. Methods: Twenty-three men (65.9 ± 7.8 years; body mass index: 29.6 ± 2.7 kg/m2; ADT duration: 33.8 ± 35.6 months) receiving ADT for ≥3 months were randomly assigned (1:1) to 20 weeks of usual care or the MED-diet (10 nutrition consults) with HIIT (4 × 4 min 85−95% heart rate peak, 3× week, starting at 12 weeks). Results: The MED-diet with HIIT significantly improved cardiorespiratory fitness (+4.9 mL·kg−1·min, p < 0.001), and body mass (−3.3 kg, p < 0.001) compared to the usual care group at 20 weeks. Clinically meaningful (≥3 points) improvements were seen in quality of life and cancer-related fatigue after 20 weeks. Conclusions: The MED-diet with HIIT increased cardiorespiratory fitness and reduced body weight in men with prostate cancer treated with ADT. Larger trials determining whether the MED-diet with HIIT translates to cardiovascular benefits are warranted.

Myeloma patients’ experiences of a supervised physical activity programme: a qualitative study

Purpose

The Myeloma: Advancing Survival Cancer Outcomes Trial (MASCOT) tested the impact of a supervised exercise programme on fatigue, clinical, and patient-reported outcomes in multiple myeloma [MM] patients. The current study explored MM patients’ experiences of the programme to guide future interventions.

Methods

Purposive sampling was used to recruit stable MM patients participating in MASCOT. Semi-structured, face-to-face interviews were conducted, transcribed verbatim, and analysed using thematic analysis.

Results

Six themes were identified. Key drivers for participation in MASCOT were “Altruism and extended cancer care”; participants wanted to give something back and assist in improving post-treatment care for MM patients, especially as after treatment “Barriers to being physically active” were a fear of damage and lack of health professional guidance. “Influences fostering change within the intervention” included physiotherapy supervision and tailored exercises, which gave participants confidence to push themselves in a safe environment and broke down misconceptions about their body. “Social support”, from both family and peers in the programme, promoted motivation and adherence. Participants expressed concerns about “Maintaining things going forward” but had identified mechanisms to aid continuation. “Physical and mental benefits” of the programme were highlighted; participants were able to do things they couldn’t before and described feeling free from the constraints of MM.

Conclusions

A post-treatment exercise intervention for MM patients was a positive experience, which enhanced participants’ physical and psychological wellbeing. Tailored gym and home-based exercises, a specialist cancer physiotherapist, and sustained support were perceived to be important for success.

Implications for cancer survivors

Exercise support for MM patients, ideally with physiotherapist supervision, should be incorporated into survivorship care to qualitatively improve patients’ quality of life, self-efficacy, and mental wellbeing.

Nutritional and Exercise Interventions in Cancer-Related Cachexia: An Extensive Narrative Review

One of the common traits found in cancer patients is malnutrition and cachexia, which affects between 25% to 60% of the patients, depending on the type of cancer, diagnosis, and treatment. Given the lack of current effective pharmacological solutions for low muscle mass and sarcopenia, holistic interventions are essential to patient care, as well as exercise and nutrition. Thus, the present narrative review aimed to analyze the nutritional, pharmacological, ergonutritional, and physical exercise strategies in cancer-related cachexia. The integration of multidisciplinary interventions could help to improve the final intervention in patients, improving their prognosis, quality of life, and life expectancy. To reach these aims, an extensive narrative review was conducted. The databases used were MedLine (PubMed), Cochrane (Wiley), Embase, PsychINFO, and CinAhl. Cancer-related cachexia is a complex multifactorial phenomenon in which systemic inflammation plays a key role in the development and maintenance of the symptomatology. Pharmacological interventions seem to produce a positive effect on inflammatory state and cachexia. Nutritional interventions are focused on a high-energy diet with high-density foods and the supplementation with antioxidants, while physical activity is focused on strength-based training. The implementation of multidisciplinary non-pharmacological interventions in cancer-related cachexia could be an important tool to improve traditional treatments and improve patients' quality of life.

A Molecular Approach to Understanding the Role of Diet in Cancer-Related Fatigue: Challenges and Future Opportunities

Cancer-related fatigue (CRF) is considered one of the most frequent and distressing symptoms for cancer survivors. Despite its high prevalence, factors that predispose, precipitate, and perpetuate CRF are poorly understood. Emerging research focuses on cancer and treatment-related nutritional complications, changes in body composition, and nutritional deficiencies that can compound CRF. Nutritional metabolomics, the novel study of diet-related metabolites in cells, tissues, and biofluids, offers a promising tool to further address these research gaps. In this position paper, we examine CRF risk factors, summarize metabolomics studies of CRF, outline dietary recommendations for the prevention and management of CRF in cancer survivorship, and identify knowledge gaps and challenges in applying nutritional metabolomics to understand dietary contributions to CRF over the cancer survivorship trajectory.

Global Trends of Nutrition in Cancer Research: A Bibliometric and Visualized Analysis Study over the Past 10 Years

The increasing application of nutrition in cancer management has attracted a great deal of research interest in recent decades. Nutritional therapies, interventions, and assessments were known to have positive effects on reducing side effects from cancer therapy. In order to identify the global research output for nutrition in cancer research, a bibliometric analysis during the past 10 years was conducted to evaluate the current status of trends, gaps, and research directions as no bibliometric studies have been conducted regarding nutrition and cancer. After the data collection, a total of 1521 articles were chosen for this bibliometric study. The visualization analysis was performed with VOSviewer. The number of publications has grown continuously since a substantial spark was identified in 2019. The majority of the authors’ affiliations were in European countries. Four cancer types were recognized among the top 10 author keywords; they were breast cancer, head and neck cancer, colorectal cancer, and gastric cancer. The Nutrients journal was the most popular among the authors as the journal published 195 articles related to the topic. In conclusion, providing evidence-based nutritional solutions for various types of cancer is essential to nutrition and cancer research. Since it is presumed to have a growing number of cancer patients worldwide with the aging population, it is vital to continuously generate research finding effective nutrition therapies for cancer patients.

Profiling patient-reported symptom recovery from oesophagectomy for patients with oesophageal squamous cell carcinoma: a real-world longitudinal study

PURPOSE

Oesophageal squamous cell carcinoma (ESCC) patients have severe symptom burden after oesophagectomy; however, longitudinal studies of symptom recovery after surgery are scarce. This study used longitudinal patient-reported outcome (PRO)-based symptoms to identify severe symptoms and profile symptom recovery from surgery in patients undergoing oesophagectomy.

METHODS

Oesophageal cancer patients (N = 327) underwent oesophagectomy were consecutively included between April 2019 and March 2020. Data were extracted from the Sichuan Cancer Hospital's Esophageal Cancer Case Management Registration Database. Symptom assessment time points were pre-surgery and 1, 3, 5, 7, 14, 21, 30, and 90 days post-surgery using the Chinese version of the MD Anderson Symptom Inventory. And each symptom was rated on an 11-point scale, with 0 being 'not present' and 10 being 'as bad as you can imagine'. The symptom recovery trajectories were profiled using mixed effect models and Kaplan-Meier analysis.

RESULTS

The most-severe symptoms on day 1 after oesophagectomy were pain, fatigue, dry mouth, disturbed sleep, and distress. The severity of symptoms peaked on day 1 after surgery. The top two symptoms were fatigue (mean: 5.44 [SD 1.88]) and pain (mean: 5.23 [SD 1.29]). Fatigue was more severe 90 days after surgery than at baseline (mean: 1.77 [SD 1.47] vs 0.65 [SD 1.05]; P < .0001). Disturbed sleep and distress persisted from pre-surgery to 90 days post-surgery; average sleep recovery time was up to 20 days, and 50.58% of patients had sleep disturbances 90 days post-surgery.

CONCLUSIONS

Early post-operative pain management after oesophagectomy should be considered. Characteristics and intervention strategies of post-operative fatigue, distress, and disturbed sleep in oesophageal cancer patients warrant further studies.

Attention to principles of exercise training: an updated systematic review of randomized controlled trials in cancers other than breast and prostate

BACKGROUND

The primary objective of this systematic review was to update our previous review on randomized controlled trials (RCTs) of exercise in cancers other than breast or prostate, evaluating: 1) the application of principles of exercise training within the exercise prescription; 2) reporting of the exercise prescription components (i.e., frequency, intensity, time, and type (FITT)); and 3) reporting of participant adherence to FITT. A secondary objective was to examine whether reporting of these interventions had improved over time.

METHODS

MEDLINE, EMBASE, CINAHL and SPORTDiscus databases were searched from 2012 to 2020. Eligible studies were RCTs of at least 4 weeks of aerobic and/or resistance exercise that reported on physiological outcomes relating to exercise (e.g., aerobic capacity, muscular strength) in people with cancer other than breast or prostate.

RESULTS

Eighty-six new studies were identified in the updated search, for a total of 107 studies included in this review. The principle of specificity was applied by 91%, progression by 32%, overload by 46%, initial values by 72%, reversibility by 7% and diminishing returns by 5%. A significant increase in the percentage of studies that appropriately reported initial values (46 to 80%, p < 0.001) and progression (15 to 37%, p = 0.039) was found for studies published after 2011 compared to older studies. All four FITT prescription components were fully reported in the methods in 58% of all studies, which was higher than the proportion that fully reported adherence to the FITT prescription components in the results (7% of studies). Reporting of the FITT exercise prescription components and FITT adherence did not improve in studies published after 2011 compared to older studies.

CONCLUSION

Full reporting of exercise prescription and adherence still needs improvement within exercise oncology RCTs. Some aspects of exercise intervention reporting have improved since 2011, including the reporting of the principles of progression and initial values. Enhancing the reporting of exercise prescriptions, particularly FITT adherence, may provide better context for interpreting study results and improve research to practice translation.

Home Coping Strategies for Fatigue Used by Patients With Lung Cancer Receiving Chemotherapy in Rural China: A Qualitative Study

BACKGROUND

Cancer-related fatigue, a distressing symptom, is frequently reported by patients with lung cancer as increasing in severity with the number of rounds of chemotherapy. Yet, patients and healthcare providers are challenged to control this fatigue. Thus, healthcare providers must have interventions to effectively enhance coping engagement in patients with lung cancer.

PURPOSE

The aims of this study were to explore how patients with lung cancer in a rural area of China undergoing chemotherapy cope with the fatigue at home and to summarize their strategies.

METHODS

A descriptive qualitative research approach was used, and data were collected using semistructured interviews. Sixteen patients with lung cancer with chemotherapy-related fatigue living in rural communities were recruited from a large, tertiary teaching hospital in Huzhou in eastern China. The transcripts of the interviews were analyzed using content analysis.

RESULTS

Coping strategies for cancer-related fatigue were delineated into the three themes of (a) psychological adjustment, (b) efforts to change lifestyles and act as a Chinese health practitioner, and (c) relying on social support.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

The participants in this study provided information on a variety of approaches to reducing/alleviating cancer-related fatigue that were influenced by Chinese culture. Healthcare providers and patients may work together in clinical settings to identify appropriate, effective coping solutions and then to incorporate these into the regular care regimen to help patients transition between hospital and home.

The Effectiveness of Nutrition Interventions Combined with Exercise in Upper Gastrointestinal Cancers: A Systematic Review

Malnutrition and muscle wasting are associated with impaired physical functioning and quality of life in oncology patients. Patients diagnosed with upper gastrointestinal (GI) cancers are considered at high risk of malnutrition and impaired function. Due to continuous improvement in upper GI cancer survival rates, there has been an increased focus on multimodal interventions aimed at minimizing the adverse effects of cancer treatments and enhancing survivors’ quality of life. The present study aimed to evaluate the effectiveness of combined nutritional and exercise interventions in improving muscle wasting, physical functioning, and quality of life in patients with upper GI cancer. A comprehensive search was conducted in MEDLINE, EMBASE, Web of Science, Cochrane Library, and CINHAL. Of the 4780 identified articles, 148 were selected for full-text review, of which 5 studies met the inclusion criteria. Whilst reviewed studies showed promising effects of multimodal interventions on physical functioning, no significant differences in postoperative complications and hospital stay were observed. Limited available evidence showed conflicting results regarding the effectiveness of these interventions on preserving muscle mass and improving health-related quality of life. Further studies examining the impact of nutrition and exercise interventions on upper GI patient outcomes are required and would benefit from reporting a core outcome set.

Exploring adult critical illness survivors' experiences of fatigue: A qualitative study

AIMS

To explore adult experiences of fatigue after discharge from an intensive care unit and identify potential management strategies.

DESIGN

An exploratory qualitative study.

METHODS

One to one audio-recorded semi-structured interviews with 17 adult survivors of critical illness in the United Kingdom, lasting up to 1 h, between September 2019 and January 2020. Anonymised and verbatim-transcribed interview data underwent a standard process of inductive thematic analysis as described by Braun and Clarke.

FINDINGS

Three themes were identified: fatigue is different for everyone; complex interrelating interactions; and personalised fatigue strategies. Fatigue was described as a distressing symptom, unique to the individual that causes an array of complex, often long-term interrelating impacts on the survivor and their wider family, made worse by a lack of understanding, empathy and support resources. Support from others, alongside interventions such as exercise, good nutrition, information and alternative therapies are used by survivors with variable degrees of success.

CONCLUSIONS

This qualitative study reports peoples' experiences of fatigue after critical illness. Findings highlight the significant impact it has on people's lives and those of their family and friends.

Fatigue prevalence in men treated for prostate cancer: A systematic review and meta-analysis

BACKGROUND

The side effects of prostate cancer (PCa) treatment are very prominent, with cancer-related fatigue (CRF) being the most common. Fatigue is a distressing symptom that interferes with daily functioning and seriously affects patient quality of life during, and for many years after, treatment. However, compared with other types of cancer, such as breast cancer, little is known about the prevalence of PCa-related fatigue.

AIM

To determine the prevalence of CRF in patients with PCa.

METHODS

A systematic search of EMBASE, PubMed, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, WANFANG DATA, Technology Journal Database and the Chinese Biological Medical Database was conducted up to July 28, 2020. Included studies measured the incidence of PCa-related fatigue and differentiated fatigue outcomes (incidence) between treatment modalities and fatigue assessment times. In our meta-analysis, both fixed and random-effects models were used to estimate the pooled prevalence of PCa-related fatigue. Subgroup analyses were performed using treatment modalities and fatigue assessment times. Publication and sensitivity bias analyses were performed to test the robustness of the associations.

RESULTS

Fourteen studies, involving 4736 patients, were eligible for the review. The pooled CRF prevalence was 40% in a total sample of 4736 PCa patients [95% confidence interval (CI): 29-52; P < 0.01; I² = 98%]. The results of the subgroup analyses showed the prevalence of CRF after androgen deprivation therapy treatment, radical prostatectomy and radiotherapy to be 42% (95%CI: 20-67, P < 0.01, I² = 91%), 21% (95%CI: 16-26, P = 0.87, I² = 0%) and 40% (95%CI: 22-58, P < 0.01, I² = 90%), respectively. The prevalence of acute and persistent fatigue was 44% (95%CI: 25-64; P < 0.01; I² = 93%) and 29% (95%CI: 25-32; P = 0.30; I² = 17%), respectively.

CONCLUSION

Our meta-analysis showed that fatigue is a common symptom in men with PCa, especially those using hormone therapy.

Nutritional Intervention Improves Nutrition Outcomes in Stomach and Colon Cancer Patients Receiving Chemotherapy: Finding from a Quasi-Experiment in Vietnam

Background: Evidence on the effects of nutritional interventions on gastrointestinal cancer patients receiving chemotherapy is not well documented. This study aims to assess the effects of nutritional intervention in patients diagnosed with stomach and colon cancer receiving chemotherapy in Vietnam. Methods: A quasi-experiment with intervention and control groups for pre- and post-intervention was carried out in cancer patients receiving chemotherapy in a university hospital in Vietnam. Patients in the intervention group were provided nutritional counseling, personalized specific dietary advice, and received oral nutrition supplements (ONSs) while patients in the control group only received nutrition counseling. Results: The weight in the intervention and control group after 2 months increased significantly by 1.4 ± 2.6 kg and 0.4 ± 2.3 kg, respectively. Muscle mass increased by 1.2 ± 4.1 cm in the intervention group, while those in the control group decreased by 0.55 ± 2.77 cm. There was no statistical significance between two groups after intervention in terms of Mid–Upper Arm Circumference (MUAC) and percentage of fat. The percentage of malnutrition based on the Scored Patient-Generated Subjective Global Assessment (PG-SGA) and Body Mass Index (BMI) declined after the intervention in both groups. According to the average treatment effect on the treated (ATT) using the propensity score matching and DiD method, participants receiving the intervention were more likely to have a higher score of weight (Coef = 0.84; 95%CI = 0.47; 2.16) and muscle mass (Coef = 1.08; 95%CI = 0.09; 2.06) between pre- and post-intervention. By contrast, the PG-SGA scores on treated participants were more likely to decrease after the intervention (Coef = −1.28; 95%CI = −4.39; −0.84). After matching, being female, living in rural areas, or having stomach cancer were still positively related to being moderately/severely malnourished by the PG-SGA, and these findings were statistically significant (p < 0.05). Conclusion: The nutritional interventions had a positive effect on weight gain, muscle mass, and reduced malnutrition. Further studies with a longer follow-up duration are needed to confirm the effects of the intervention.

The Benefit of Enhanced Daycare of Traditional Chinese Medicine for Cancer Treatment Related Adverse Events: A Retrospective Study of Medical Records

Objective:

Cancer patients undergo therapies that might lead to severe adverse events. The enhanced daycare of Traditional Chinese medicine (TCM) we describe was intended to help cancer patients suffering from severe adverse events to obtain relief. We used the Taiwan brief version of the Common Terminology Criteria for Adverse Events Version 4.0 (Taiwan brief version questionnaire of CTCAE) as a primary measurement to evaluate the efficacy of the enhanced day care of TCM. The secondary measurements were the Taiwanese version of the Brief Fatigue Inventory (BFI-T) questionnaire and the World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire, which were used to quantify fatigue and quality of life (QOL), respectively.

Methods/Design:

This is a retrospective study of medical records. There were 401 patients treated with enhanced daycare of TCM from June 2017 to November 2019.

Results:

Among 22 common adverse symptoms in the Taiwan brief version questionnaire of CTCAE4.0, 14 symptoms achieved a significant improvement, and the change of the total scores was also statistically significant (P < .001). Cancer stages II to IV showed significant improvement on the CTCAE and BFI-T; stage I only showed improvement on the BFI-T. On the WHOQOL questionnaire, there was a statistically significant difference in self-evaluation of the quality of life (P = .001) and self-evaluation of the total health condition aspect (P < .001).

Conclusions:

The enhanced TCM daycare program helped cancer patients decrease the severity of their adverse events and improve their fatigue and QOL. ClinicalTrials.gov identifier: NCT04606121.

Benefits of Exercise and Astaxanthin Supplementation: Are There Additive or Synergistic Effects?

A healthy lifestyle is essential for maintaining physical and mental health. Health promotion, with a particular emphasis on regular exercise and a healthy diet, is one of the emerging trends in healthcare. However, the way in which exercise training and nutrients from dietary intake interact with each other to promote additive, synergistic, or antagonistic effects on physiological functions leading to health promotion, and the possible underlying biomolecular mechanisms of such interactions, remain poorly understood. A healthy diet is characterized by a high intake of various bioactive compounds usually found in natural, organic, and fresh foodstuffs. Among these bioactive compounds, astaxanthin (ASX), a red carotenoid pigment especially found in seafood, has been recognized in the scientific literature as a potential nutraceutical due to its antioxidant, anti-inflammatory, and neurotrophic properties. Therefore, scientists are currently exploring whether this promising nutrient can increase the well-known benefits of exercise on health and disease prevention. Hence, the present review aimed to compile and summarize the current scientific evidence for ASX supplementation in association with exercise regimes, and evaluate the additive or synergistic effects on physiological functions and health when both interventions are combined. The new insights into the combination paradigm of exercise and nutritional supplementation raise awareness of the importance of integrative studies, particularly for future research directions in the field of health and sports nutrition science.

Prevalence and experience of fatigue in survivors of critical illness: a mixed-methods systematic review

We conducted a mixed methods systematic review to investigate the prevalence, experience and management of fatigue in survivors of critical illness. We identified 76 studies investigating fatigue or vitality in adults discharged from an intensive care unit and split the extracted data into three datasets: vitality scores from the Short Form Health Survey-36 (n = 54); other quantitative data (n = 19); and qualitative data (n = 9). We assessed methodological quality using critical appraisal skills programme tools. We adopted a segregated approach to mixed-methods synthesis. In a final step, we attributed combined results to one of four qualitative themes: prevalence and severity; contributing factors; impacts on quality of life; and assessment and management. Prevalence of fatigue ranged from 13.8 to 80.9%. Short Form Health Survey-36 vitality scores were commonly used as a marker of fatigue. Vitality scores reached a nadir approximately one month following ICU discharge (mean (SD) 56.44 (32.30); 95%CI 52.92-59.97). They improved over time but seldom reached reference population scores. Associated biological, disease-related and psychological factors included age, poor pre-morbid status, sleep and psychological disturbance. Qualitative data highlight the profound negative impact of fatigue on survivors' quality of life. Survivors seldom had any information provided on the potential impact of fatigue. No fatigue assessment tools specific to critical illness or evidence-based interventions were reported. Fatigue is highly prevalent in survivors of critical illness, and negatively impacts recovery. Further research on developing fatigue assessment tools specifically for critically ill patients and evaluating the impact of pharmacological and non-pharmacology interventions is needed.

Nutrition Education Seminars for Prostate Cancer-Diet and Prostate Program: Evaluation and Recommendations (DAPPER Study)

Nutrition is important for prostate cancer (PCa) care as it may influence PCa progression and risk of comorbid diseases. The aim of this pilot study was to assess changes in knowledge and satisfaction in men with PCa following attendance at a nutrition education seminar. Fifty-two men with PCa attended nutrition education seminars instructed by a Registered Dietitian. Participants completed the Revised General Nutrition Knowledge Questionnaire (GNKQ-R) preseminar and 2 weeks postseminar, along with a satisfaction survey. Increased nutrition knowledge was observed through a significant (P = 0.023) improvement in mean scores of 71.6% (P < 0.005) preseminar compared with 79.3% (P < 0.005) postseminar on the GNKQ-R. Participants reported the seminar as a satisfactory method for meeting their diet information needs. Using thematic analysis 3 themes emerged: importance of diet information, desire for an integrative approach, and the value of group learning. This pilot study found that a group nutrition education seminar may be an effective and satisfactory approach to fulfilling the dietary information needs of this population. Group education may be an economically sustainable approach with potential application in other tumour sites or health conditions.

Integrative Oncology Education: An Emerging Competency for Oncology Providers

A growing number of cancer patients use complementary and alternative therapies during and after conventional cancer treatment. Patients are often reluctant to discuss these therapies with their oncologist, and oncologists may have limited knowledge and confidence on how to advise patients on the appropriate use. Integrative oncology is a patient-centered, evidence-informed field that utilizes mind-body practices, lifestyle modifications and/or natural products interwoven with conventional cancer treatment. It prioritizes safety and best available evidence to offer appropriate interventions alongside conventional care. There are few opportunities for oncologists to learn about integrative oncology. In this commentary, we highlight the Integrative Oncology Scholars (IOS) program as a means to increase competency in this growing field. We provide an overview of several integrative oncology modalities that are taught through this program, including lifestyle modifications, physical activity, and mind-body interventions. We conclude that as more evidence is generated in this field, it will be essential that oncology healthcare providers are aware of the prevalent use of these modalities by their patients and cancer centers include Integrative Oncology trained physicians and other healthcare professionals in their team to discuss and recommend evidence-based integrative oncology therapies alongside conventional cancer treatments to their patients.

Resistance Exercise in Prostate Cancer Patients: a Short Review

Purpose of Review

The aim of this paper is to provide an overview of recent findings concerning the utilization of resistance exercise (RE) in prostate cancer (PCa), in particular as pertaining to the management of cancer therapy side effects.

Recent Findings

As of late, studies investigating the effects of RE in PCa patients have found positive effects on muscle strength, body composition, physical functioning, quality of life, and fatigue. The combination of RE and impact training appears to decrease the loss of bone mineral density. RE seems to be well accepted and tolerated, even by patients with bone metastatic disease, although a modification of the RE prescription is often necessary.

Summary

In PCa patients, RE has been well-researched and the data are clear that it is beneficial in multiple ways. Future directions should look at the long-term effects of RE, including mortality and relapse, as well as implementation of exercise programs.

Safety, Precautions, and Modalities in Cancer Rehabilitation: an Updated Review

PURPOSE OF REVIEW

Providing rehabilitation to patients with cancer can be challenging due to the medical complexity associated with the illness and its treatments. This article provides the reader with a summary of frequently encountered medical conditions in the cancer population and associated safety considerations and precautions. An update on treatment modalities commonly used for symptom management is also presented.

RECENT FINDINGS

Cancer and cancer treatments can cause changes in multiple organ systems. Special considerations and precautions are necessary to provide safe and effective rehabilitation. Physical modalities can be used as monotherapy or adjunct to treatment for common cancer-related side effects with recent studies noting benefit with a variety of modalities.

SUMMARY

Detailed assessment of the cancer patient is necessary before implementing a rehabilitation program. Understanding cancer and side effects of treatments, including newer options, are necessary to provide safe care.

Inflammation Is a Mediating Factor in the Association between Lifestyle and Fatigue in Colorectal Cancer Patients

Simple Summary

Fatigue is common among colorectal cancer patients. A healthier lifestyle may beneficially affect fatigue, although data are sparse. A healthier lifestyle may result in lower levels of inflammation, which is one of the suggested mechanisms by which lifestyle could influence fatigue. In an observational study, we investigated 1) whether a healthier lifestyle was associated with less fatigue among colorectal cancer patients, and 2) whether this association could be explained by inflammation. We showed that a healthier lifestyle was associated with less fatigue, and that inflammation levels mediated this association. Future intervention studies should investigate whether improving lifestyle after cancer diagnosis results in lowering of inflammation markers and subsequent fatigue.

Abstract

Fatigue is very common among colorectal cancer (CRC) patients. We examined the association between adherence to the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) lifestyle recommendations and fatigue among stage I-III CRC patients, and whether inflammation mediated this association. Data from two prospective cohort studies were used. Adherence to the WCRF/AICR recommendations was expressed as a score ranging from 0–7, and assessed shortly after diagnosis. Six months post-diagnosis, fatigue was assessed with the European Organization for Research and Treatment of Cancer quality of life questionnaire C30 (EORTC QLQ-C30), and in a subpopulation, the plasma levels of inflammation markers (IL6, IL8, TNFα, and hsCRP) were assessed. Multiple linear regression analyses were performed to investigate the association between adherence to the WCRF/AICR recommendations and fatigue. To test mediation by inflammation, the PROCESS analytic tool developed by Hayes was used. A higher WCRF/AICR adherence score was associated with less fatigue six months after diagnosis (n = 1417, β −2.22, 95%CI −3.65; −0.78). In the population of analysis for the mediation analyses (n = 551), the total association between lifestyle and fatigue was (β −2.17, 95% CI −4.60; 0.25). A statistically significant indirect association via inflammation was observed (β −0.97, 95% CI −1.92; −0.21), explaining 45% of the total association between lifestyle and fatigue (−0.97/−2.17 × 100). Thus, inflammation is probably one of the underlying mechanisms linking lifestyle to fatigue.

Living with Metastatic Cancer: A Roadmap for Future Research

Simple Summary

Although people with metastatic cancer are living longer with their disease, they are faced with challenges that can interfere with their quality of life. These challenges include worsening disease, survival time, symptoms, distress, and financial problems. The aim of this review paper is to describe a framework to guide future efforts to address these challenges. The framework includes the risk factors (predisposing factors), triggers (precipitating factors), and responses (perpetuating factors) that contribute to the onset and maintenance of problems in living with metastatic cancer. We conclude by suggesting areas for future work to prevent problems, manage triggers, and reduce unhelpful responses.

Abstract

Living with metastatic cancer, or metavivorship, differs from cancer survivorship and has changed as novel treatments have increased survival time. The purpose of this narrative review is to describe factors that impact challenges in metavivorship within a conceptual framework to guide future research. This review focuses on the specific metavivorship outcomes of progressive disease, survival time, symptoms, distress, financial toxicity, and quality of life. We describe the predisposing, precipitating, and perpetuating (3P) model of metavivorship. Understanding the biological, psychological, and social 3P factors that contribute to the development and maintenance of challenges in metavivorship provides a roadmap for future research. Implications of this model include prevention by targeting predisposing factors, management of precipitating factors after onset of metastatic disease, and treatment of perpetuating factors to reduce symptoms and improve quality of life during the chronic phase of metavivorship. This can be accomplished through biopsychosocial screening efforts, monitoring of patient-reported outcomes, education and communication interventions, interdisciplinary symptom management, advance care planning, and behavioral interventions to cultivate psychological resilience.

The Role of Nutritional Support in Cured/Chronic Patients

Improvements in Clinical Oncology, due to earlier diagnoses and more efficient therapeutic strategies, have led to increased numbers of long-term survivors, albeit many with chronic diseases. Dealing with the complex care needs of these survivors is now an important part of Medical Oncology. Suitable diet and physical activity regimes will be important in maintaining their health. This paper will review what we know and what we can do in the near future for these patients.

A Randomized Controlled Trial Testing the Effectiveness of Coping with Cancer in the Kitchen, a Nutrition Education Program for Cancer Survivors

Following a diet rich in whole grains, vegetables, fruit, and beans may reduce cancer incidence and mortality. The aim of this study was to investigate the effect of Coping with Cancer in the Kitchen (CCK), an 8 week in-person program offering education, culinary demonstrations and food tasting, and psychosocial group support, compared to receiving CCK printed materials by mail on knowledge, confidence, and skills in implementing a plant-based diet. A total of 54 adult cancer survivors were randomly assigned to intervention (n = 26) and control groups (n = 27) with assessments at baseline, 9, and 15 weeks via self-administered survey. The response rate was 91% at 9 weeks and 58% at 15 weeks. The majority of our study participants were female breast cancer survivors (58%) who had overweight or obesity (65%). Compared with the control, there were significant (p < 0.05) increases in intervention participants’ knowledge about a plant-based diet at weeks 9 and 15, reductions in perceived barriers to eating more fruits and vegetables at week 9, and enhanced confidence and skills in preparing a plant-based diet at week 15. There was a significant reduction in processed meat intake but changes in other food groups and psychosocial measures were modest. Participation in CCK in person increased knowledge, skills, and confidence and reduced barriers to adopting a plant-based diet. Positive trends in intake of plant-based foods and quality of life warrant further investigation in larger-scale studies and diverse populations.

Cost-Effectiveness Analysis of Supervised Exercise Training in Men with Prostate Cancer Previously Treated with Radiation Therapy and Androgen-Deprivation Therapy

BACKGROUND

Exercise for prostate cancer (PCa) survivors has been shown to be effective in addressing metabolic function and associated co-morbidities, as well as sarcopenia and significant functional impairment resulting from long-term androgen deprivation. Evidence on the cost-effectiveness of exercise interventions for PCa, however, is lacking, thus the aim of this study was to determine the cost-effectiveness of a supervised exercise intervention for long-term PCa survivors who previously received radiation therapy and androgen-deprivation therapy.

METHODS

Cost-effectiveness analysis from an Australian healthcare-payer perspective was conducted using patient-level data from a multicentre randomised controlled trial (RCT) of supervised exercise training (resistance and aerobic) compared to receiving printed exercise material and a recommendation to exercise in long-term PCa survivors (> 5 years post-diagnosis). Analysis was undertaken for the 6-month supervised exercise portion of the intervention, which involved 100 men aged between 62 and 85 years, 50 in each arm. The primary outcome was cost per quality-adjusted life-years (QALYs).

RESULTS

A 6-month supervised exercise intervention for PCa survivors resulted in an incremental cost-effectiveness ratio of AU$64,235 (2018 AUD) at an incremental cost of AU$546 per person and a QALY gain of 0.0085. At a willingness-to-pay of AU$50,000, the probability that the intervention is cost-effective was 41%. Sensitivity analysis showed that maintenance of benefits via a 6-month home-based intervention, immediately following the supervised intervention, lowered the cost per QALY gained to AU$32,051.

DISCUSSION

This is the first cost-effectiveness analysis of exercise for PCa survivors. The intervention was effective, but unlikely to be cost-effective at the generally accepted willingness-to-pay of AU$50,000 per QALY. It is likely that evidence to support cost savings from post-intervention outcomes would reveal greater benefits and contribute to a more comprehensive cost-effectiveness analysis. Future RCTs should incorporate longer follow-up durations and collection of data to support modelling to capture future health benefits. Measures of quality of life or utility more sensitive to the impact of physical activity would also improve future economic evaluations.

Cooking for Vitality: Pilot Study of an Innovative Culinary Nutrition Intervention for Cancer-Related Fatigue in Cancer Survivors

(1) Background: Cancer-related fatigue (CRF) is one of the most prevalent and distressing side effects experienced by patients with cancer during and after treatment, and this negatively impacts all aspects of quality of life. An increasing body of evidence supports the role of poor nutritional status in the etiology of CRF and of specific diets in mitigating CRF. We designed a group-based two session culinary nutrition intervention for CRF, Cooking for Vitality (C4V), aimed at increasing understanding of how food choices can impact energy levels and establishing basic food preparation and cooking skills as well as the application of culinary techniques that minimize the effort/energy required to prepare meals. The purpose of this pilot mixed-method study was to evaluate: Feasibility of the experimental methods and intervention; acceptability and perceived helpfulness of intervention; and to obtain a preliminary estimate of the effectiveness of the intervention on fatigue (primary outcome), energy, overall disability, and confidence to manage fatigue (secondary outcomes). (2) Methods: Prospective, single arm, embedded mixed-methods feasibility study of cancer survivors with cancer-related fatigue was conducted. Participants completed measures at baseline (T0), immediately following the intervention (T1), and three months after the last session (T2). Qualitative interviews were conducted at T2. (3) Results: Recruitment (70%) and retention (72%) rates along with qualitative findings support the feasibility of the C4V intervention for cancer survivors living with CRF (program length and frequency, ease of implementation, and program flexibility). Acceptability was also high and participants provided useful feedback for program improvements. Fatigue (FACT-F) scores significantly improved from T0–T1 and T0–T2 (p < 0.001). There was also a significant decrease in disability scores (WHO-DAS 2.0) from T0–T2 (p = 0.006) and an increase in POMS-Vigor (Profile of Mood States) from T0–T1 (p = 0.018) and T0–T2 (p = 0.013). Confidence in managing fatigue improved significantly from T0–T1 and T0–T2 (p < 0.001). (4) Conclusions: The results suggest that the C4V program was acceptable and helpful to patients and may be effective in improving fatigue levels and self-management skills. A randomized controlled trial is required to confirm these findings.

Identification of Modulated MicroRNAs Associated with Breast Cancer, Diet, and Physical Activity

Simple Summary

Healthy diet and physical activity are able to induce beneficial molecular modifications that have been associated with a lower risk of breast cancer (BC) incidence and a better prognosis for BC patients. Although the beneficial effects of healthy lifestyle have been described, the beneficial epigenetic modifications induced by dietary and exercise intervention in BC patients have not been elucidated yet. On these bases, the aim of the present study was to computationally identify microRNAs (miRNAs) strictly associated with BC progression and with dietary and exercise interventions. Through several computational approaches, a set of miRNAs modulated by diet and exercise and useful as diagnostic and prognostic biomarkers for BC was identified. The results obtained represent the starting point for further validation analyses performed on BC patients undergoing lifestyle interventions to propose the miRNAs here identified as novel biomarkers for BC management.

Abstract

Background: Several studies have shown that healthy lifestyles prevent the risk of breast cancer (BC) and are associated with better prognosis. It was hypothesized that lifestyle strategies induce microRNA (miRNA) modulation that, in turn, may lead to important epigenetic modifications. The identification of miRNAs associated with BC, diet, and physical activity may give further insights into the role played by lifestyle interventions and their efficacy for BC patients. To predict which miRNAs may be modulated by diet and physical activity in BC patients, the analyses of different miRNA expression datasets were performed. Methods: The GEO DataSets database was used to select miRNA expression datasets related to BC patients, dietary interventions, and physical exercise. Further bioinformatic approaches were used to establish the value of selected miRNAs in BC development and prognosis. Results: The analysis of datasets allowed the selection of modulated miRNAs associated with BC development, diet, and physical exercise. Seven miRNAs were also associated with the overall survival of BC patients. Conclusions: The identified miRNAs may play a role in the development of BC and may have a prognostic value in patients treated with integrative interventions including diet and physical activity. Validation of such modulated miRNAs on BC patients undergoing lifestyle strategies will be mandatory.

Application of physical exercise therapies in breast cancer survivors and their effects on the inflammatory profile: A narrative review

BACKGROUND

One of the adverse effects of cancer treatments is the exacerbation of inflammation, which generates numerous limitations and contributes to the development of several comorbidities and the recurrence of cancer itself. Physical exercise (PE) has been proposed as an efficient complementary strategy to combat the inflammatory effects of oncological treatments and to prevent the development of comorbidities, but its adequate application in breast cancer survivors (BCS) requires the establishment of consensuses and practical recommendations.

OBJECTIVE

This study aimed to review the randomized controlled trials that evaluated the influence of PE in the inflammatory profile of BCS.

METHODS

The search for articles published between 1999 and 2020 was done in PsycINFO, PubMed, Cochrane, Science Direct, and Scopus databases.

RESULTS

Current knowledge reveals the effectiveness of PE in the functional independence and health of BCS. Evidence of the capacity of PE to improve the inflammatory profile and the immune response in BCS has also been described. However, the heterogeneity of the studies regarding structural training variables, types of exercise, stages of intervention, and severity of the disease, still do not allow the establishment of precise guidelines for the prescription and progression of exercise to improve the inflammatory process in BCS.

DISCUSSION

. This review suggests a possible strategy to be used in the assessment, training prescription, and rehabilitation of BCS, to support the development of new studies and the work of exercise professionals in the prescription and application of physical training to improve health and inflammatory status in BCS.
