Barriers and facilitators to healthy lifestyle and acceptability of a dietary and physical activity intervention among African Caribbean prostate cancer survivors in the UK: a qualitative study

Translation and validation of a lifestyle questionnaire related to prostate cancer

BACKGROUND

Valid and reliable instruments are needed to measure prostate cancer-related lifestyle changes, plan evidence-based interventions to modify lifestyle, and improve treatment outcomes. Due to the lack of appropriate instruments, this study was conducted to translate the Effects of Prostate Cancer upon Lifestyle Questionnaire (EPCLQ) into Persian and examine its psychometric properties in a sample of Iranian older adults with prostate cancer.

METHODS

This methodological study was carried out between 2021 and 2022. Initially, the EPCLQ, comprising 36 items, was translated into Persian through a meticulous translation and back-translation procedure. Subsequent steps involved the assessment of face validity, qualitative content validity, content validity index, content validity ratio, construct validity via confirmatory factor analysis, and reliability testing of the Persian version of the EPCLQ.

RESULTS

The psychometric evaluation led to the exclusion of 4 items from the EPCLQ. The refined model demonstrated satisfactory fit indices (PCFI = 0.732, PNFI = 0.696, CMIN/DF = 2.29, RMSEA = 0.072, IFI = 0.920, CFI = 0.919, and GFI = 0.971), indicating an appropriate fit of the final model. The internal consistency, as measured by Cronbach's alpha, was 0.67, and the intraclass correlation coefficient for the questionnaire was 0.938, reflecting high reliability.

CONCLUSIONS

The Persian version of the EPCLQ, now consisting of 32 items, has been validated and is reliable for assessing the impact of prostate cancer on lifestyle among older adults. Its simplicity and the clarity of the items make it suitable for use in clinical settings or during home visits for follow-up assessments.

A Systematic Review of Dietary Interventions for Cancer Survivors and Their Families or Caregivers

Family or caregiver engagement has the potential to support healthy dietary changes among cancer survivors. However, little is known about these family- or caregiver-involved dietary interventions and their effects. This systematic review aimed to identify the behavior change techniques (BCTs) used in dietary interventions for cancer survivors and their families or caregivers and to synthesize intervention effects on dietary and health outcomes. Following the PRISMA guidelines, we conducted systematic searches in three databases and identified 12 trials (16 peer-reviewed manuscripts) for inclusion in this review. Data were extracted from these manuscripts and the BCT taxonomy was used to identify the BCTs. A total of 38 BCTs were identified from 12 trials, 13 of which were used in at least half of the 12 trials. Ten studies reported significant intervention effects on health outcomes (e.g., adiposity) and six suggested significant improvements in dietary behaviors (e.g., fruit and vegetable intake). Overall, this review found that family- or caregiver-involved interventions for cancer survivors significantly improved dietary and health outcomes. Future research should identify BCTs particularly for dietary changes and develop effective dyadic strategies to facilitate diet-related interactions between survivors and their families or caregivers to enhance their engagement in healthy diets.

Improving adult behavioural weight management services for diverse UK Black Caribbean and Black African ethnic groups: a qualitative study of insights from potential service users and service providers

Background

A significantly higher proportion of UK Black ethnic adults live with overweight or obesity, compared to their White British counterparts. The role of obesity in excess infection rates and mortality from COVID-19 has increased the need to understand if weight management interventions are appropriate and effective for Black ethnic groups. There is a paucity of existing research on weight management services in Black populations, and whether anticipated or experienced institutional and interpersonal racism in the healthcare and more widely affects engagement in these services. Understanding the lived experience of target populations and views of service providers delivering programmes is essential for timely service improvement.

Methods

A qualitative study using semi-structured interviews was conducted in June-October 2021 among 18 Black African and Black Caribbean men and women interested in losing weight and 10 weight management service providers.

Results

The results highlighted a positive view of life in the United Kingdom (UK), whether born in the UK or born abroad, but one which was marred by racism. Weight gain was attributed by participants to unhealthy behaviours and the environment, with improving appearance and preventing ill health key motivators for weight loss. Participants relied on self-help to address their overweight, with the role of primary care in weight management contested as a source of support. Anticipated or previously experienced racism in the health care system and more widely, accounted for some of the lack of engagement with services. Participants and service providers agreed on the lack of relevance of existing services to Black populations, including limited culturally tailored resources. Community based, ethnically matched, and flexibly delivered weight management services were suggested as ideal, and could form the basis of a set of recommendations for research and practice.

Conclusion

Cultural tailoring of existing services and new programmes, and cultural competency training are needed. These actions are required within systemic changes, such as interventions to address discrimination. Our qualitative insights form the basis for advancing further work and research to improve existing services to address the weight-related inequality faced by UK Black ethnic groups.

Structural Racism, Lifestyle Behaviors, and Obesity-related Cancers among Black and Hispanic/Latino Adults in the United States: A Narrative Review

One in three adults in the United States has obesity; a chronic disease that is implicated in the etiology of at least 14 cancers. Cancer is the leading cause of death among U.S. Hispanic/Latino adults and the second most common cause of death, after cardiovascular disease, for Black adults. Our country's legacy in overt discrimination (e.g., slavery, segregation) generated inequities across all spheres in which people function as defined by the socioecological model-biological, individual, community, structural-and two of the many areas in which it manifests today are the disproportionate burden of obesity and obesity-related cancers in populations of color. Inequities due to environmental, social, and economic factors may predispose individuals to poor lifestyle behaviors by hindering an individual's opportunity to make healthy lifestyles choices. In this review, we examined the evidence on obesity and the lifestyle guidelines for cancer prevention in relation to cancer risk and outcomes for Black and Hispanic/Latino adults. We also discussed the role of structural and societal inequities on the ability of these two communities to adopt and maintain healthful lifestyle behaviors in accordance with the lifestyle guidelines for cancer prevention and control.

Adherence to lifestyle recommendations among Norwegian cancer survivors and the impact of traditional and complementary medicine use: the Tromsø Study 2015-2016

INTRODUCTION

Adherence to healthy lifestyle recommendations has positive effects on cancer outcomes yet adherence is low among cancer survivors. Differences in adherence between women and men, phase of survivorship, and other factors that might increase adherence, like the use of traditional and complementary medicine (T&CM), need to be explored. We aimed to study the adherence to national recommendations for a healthy diet (daily intake of ≥ 5 portions of fruit/vegetables), physical activity (150 min of moderate-intensity or 75 min of high-intensity/week), normal body mass index (BMI) (18.5-24.9 kg/m2), non-smoking, and low-risk alcohol consumption (women ≤ 10 g/day, men ≤ 20 g/day) among Norwegian cancer survivors and their associations with sex, the use of T&CM, and survivorship phase.

METHODS

We used logistic regression, independent sample t-test, and chi-square test to study self-reported (diet, physical activity, smoking, alcohol consumption) and measured (BMI) adherence in 1530 cancer survivors (40 years and above, participating in the population-based Tromsø Study conducted in 2015-2016 (65% attendance). We dichotomized all assessed lifestyle recommendations (adherence = 1 point, non-adherence = 0 points), and created a score for every recommendation (0-5 points). Adherence to individual lifestyle recommendations and the use of T&CM as well as the phase of survivorship was adjusted for sex, age, income, and living with a partner.

RESULTS

Adherence to recommendations was 7.5% for diet, 85.3% for physical activity, 30.5% for BMI, 89.3% for non-smoking, and 87.6% for alcohol consumption. In total 2.3% adhered to all five recommendations concurrently (mean score 2.96 [SD = 0.86]). Women adhered to more recommendations concurrently compared to men (3.03 [SD = 0.90] vs. 2.89 [SD = 0.80] points respectively, [p = .012]). In total, 31% reported the use of T&CM and there were no differences in adherence to individual lifestyle recommendations or concurrent adherence in overall T&CM use compared to non-use. Users of self-help techniques were more likely to adhere to the recommendations of diet (aOR 2.69, 95% CI 1.45-4.98) and physical activity (aOR 6.26, 95% CI 1.51-25.92). Users of traditional healers and users of more than one T&CM modality were less likely to adhere to the low-risk alcohol consumption recommendation, (aOR 0.32, 95% CI 0.13-0.77, and aOR 0.53, 95% CI 1.08-2.17, respectively) compared to T&CM non-users. Survivors with cancer previously (1162) had higher odds of adhering to the recommendation of diet (aOR 2.66, 95% CI 1.36-5.19) than survivors with cancer presently (n = 368), but not to other recommendations.

CONCLUSION

The health of cancer survivors can be improved through adherence to lifestyle recommendations, yet our study found partial adherence among survivors in Norway, in accordance with findings from other countries. Although overall T&CM use was not associated with higher adherence to lifestyle recommendations, differences in adherence were seen among individual modalities like the use of self-help techniques and traditional healers. Our results suggest the need for intensified follow-up of lifestyle with attention to male survivors and diet among all survivors throughout the cancer survivorship continuum.

Barriers and facilitators to accessing and utilising post-treatment psychosocial support by Black men treated for prostate cancer-a systematic review and qualitative synthesis

PURPOSE

To synthesise findings from published studies on barriers and facilitators to Black men accessing and utilising post-treatment psychosocial support after prostate cancer (CaP) treatment.

METHODS

Searches of Medline, Embase, PsycInfo, Cochrane Database of Systematic Reviews and Central, CINAHL plus and Scopus were undertaken from inception to May 2021. English language studies involving Black men aged ≥18 and reporting experiences of, or suggestions for, psychosocial support after CaP treatment were included. Low or moderate quality studies were excluded. Searches identified 4,453 articles and following deduplication, 2,325 were screened for eligibility. Two independent reviewers carried out screening, quality appraisal and data extraction. Data were analysed using thematic synthesis.

RESULTS

Ten qualitative studies involving 139 Black men were included. Data analysis identified four analytical constructs: experience of psychosocial support for dealing with treatment side effects (including impact on self-esteem and fear of recurrence); barriers to use of psychosocial support (such as perceptions of masculinity and stigma around sexual dysfunction); facilitators to use of psychosocial support (including the influence of others and self-motivation); and practical solutions for designing and delivering post-treatment psychosocial support (the need for trusted healthcare and cultural channels).

CONCLUSIONS

Few intervention studies have focused on behaviours among Black CaP survivors, with existing research predominantly involving Caucasian men. There is a need for a collaborative approach to CaP care that recognises not only medical expertise but also the autonomy of Black men as experts of their illness experience, and the influence of cultural and social networks.

Psychosocial Determinants of Lifestyle Change after a Cancer Diagnosis: A Systematic Review of the Literature

Simple Summary

Although cancer survivors may experience health benefits from favorable lifestyle changes, many cancer survivors do not adhere to lifestyle recommendations or make favorable lifestyle changes after cancer diagnosis. This systematic review of the literature aimed to provide an overview of the scientific literature on sociodemographic, psychological and social determinants that may facilitate or hamper lifestyle change after the diagnosis cancer. It provides a structured overview of the large variety of determinants of changes in different lifestyle behaviors (physical activity, diet, smoking, alcohol, sun protection, and multiple lifestyle behaviors) derived from the 123 included papers (71 quantitative and 52 qualitative). Findings demonstrate the important role of oncology healthcare professionals in promoting healthy lifestyle changes in cancer survivors and inform researchers and healthcare professionals about the methods and strategies they can use to promote healthy lifestyle changes in cancer survivors.

Abstract

The aim of this study is to provide a systematic overview of the scientific literature on sociodemographic, psychological and social determinants that may facilitate or hamper lifestyle change after the diagnosis cancer. Four databases (PubMed, PsychINFO, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Web of Science) were searched for relevant papers up to October 2021. Of the 9586 references yielded by the literature search, 123 papers were included: 71 quantitative and 52 qualitative papers. Findings showed a large variety of determinants influencing lifestyle change after cancer diagnosis, with differences between lifestyle behaviors (physical activity, diet, smoking, alcohol, sun protection, and multiple lifestyle behaviors) and findings from quantitative vs. qualitative studies. Findings demonstrate the important role of oncology healthcare professionals in promoting healthy lifestyle changes in cancer survivors. In addition, findings inform researchers involved in the development of health promotion programs about the methods and strategies they can use to promote healthy lifestyle changes in cancer survivors. Favorable lifestyle changes are expected to have beneficial effects on cancer risk and overall health in cancer survivors.

Codesigning a patient support portal with health professionals and men with prostate cancer: An action research study

INTRODUCTION

The supportive care needs of men with prostate cancer (PCa) have been well documented, but little is known about how an online portal may address these. This study sought to determine priority issues facing men with PCa, barriers and enablers to accessing care and whether health professionals (HPs) and men would support the inclusion of a patient-reported outcome (PRO) comparator tool.

METHODS

We conducted four online focus groups with HPs recruited from healthcare services in Victoria, followed by seven online codesign workshops with men with PCa, recruited through the Victorian Prostate Cancer Outcomes Registry, Prostate Cancer Foundation Australia and the Cancer Council Victoria. Men were eligible to participate if they had lived experience of PCa and access to the internet. We analysed focus groups thematically. Workshops were analysed using descriptive-content analysis.

RESULTS

HPs (n = 39) highlighted that men had shifting priorities over time, but noted the importance of providing information to men in lay terms to assist in treatment decision-making and side-effect management. HPs identified key enablers to men accessing support services such as practice nurses, partners and having men share their stories with each other. HPs raised financial, cultural, geographic and emotional barriers to accessing supportive care. Inclusion of a PRO comparator tool received mixed support from HPs, with 41% (n = 16) supportive, 49% (n = 19) unsure and 10% (n = 4) not supportive. Men involved in workshops (n = 28) identified informational needs to assist in treatment decision-making and side-effect management as the top priority throughout care. Men described support groups and practice nurses as key enablers. Short consultation times and complex information were described as barriers. Unlike HPs, all men supported the inclusion of a PRO comparator tool in a portal.

CONCLUSIONS

Our findings suggest that a patient support portal should provide information in lay terms that address the shifting priorities of men with PCa. Men with PCa would welcome the development of a portal to centralize support information and a PRO comparator tool to prompt health-seeking behaviour. Future research will implement these findings in the development of a portal, and pilot and evaluate the portal within a population-based sample.

PATIENT OR PUBLIC CONTRIBUTION

This project adopted a codesign approach including both men with PCa and HPs involved in PCa care. Men with PCa also formed part of the study's steering committee and consumer advisory groups. HPs were consulted in a serious of online focus groups. Subsequently, men with PCa and their support persons participated in workshops. Men with PCa were also involved in the preparation of this manuscript.

Physical exercise habits, lifestyle behaviors, and motivation to change among men with prostate cancer: a cross-sectional study

PURPOSE

To describe the physical exercise (PE) habits, lifestyle, and motivation to change toward healthier behaviors in patients newly diagnosed with prostate cancer (PCa).

METHODS

A cross-sectional study was conducted in an Italian hospital setting. Men newly diagnosed with PCa were consecutively invited to participate in a structured interview that was conducted either in person or by telephone.

RESULTS

The mean age of the 40 participants was 70.5 ± 6.6 (range 50-84). Most participants (65%) reported they were physically active, but more than half of the sample did not reach the recommended PE level. However, 40% of participants would be interested in participating in an exercise program. Only 10% of participants were current smokers, but 90% drank alcohol, and 62.5% were overweight/obese. Almost all participants were not willing to change their habits.

CONCLUSIONS

A high proportion of Italian men are insufficiently active when diagnosed with PCa. Moreover, even when exposed to behavioral risk factors, they are not willing to change their lifestyle. Health-care professionals who deal with men newly diagnosed with PCa should take advantage of the teachable moment and apply strategies that support patients' motivation to exercise and adherence to healthier lifestyles.

TRIAL REGISTRATION

The study was prospectively registered in ClinicalTrial.gov NCT03982095 on June 11, 2019.

Supportive care needs of men with prostate cancer: A systematic review update

BACKGROUND

Prostate cancer is highly prevalent and impacts profoundly on patients' quality of life, leading to a range of supportive care needs.

METHODS

An updated systematic review and thematic synthesis of qualitative data using the Preferred Reporting Items for Systematic Reviews (PRISMA) reporting guidelines, to explore prostate cancer patients' experience of, and need for, supportive care. Five databases (Medline, Embase, PsycInfo, Emcare and ASSIA) were searched; extracted data were synthesised using Corbin and Strauss's 'Three Lines of Work' framework.

RESULTS

Searches identified 2091 citations, of which 105 were included. Overarching themes emerged under the headings of illness, everyday life and biographical work. Illness work needs include consistency and continuity of information, tailored to ethnicity, age and sexual orientation. Biographical work focused on a desire to preserve identity in the context of damaging sexual side effects. Everyday life needs centred around exercise and diet support and supportive relationships with partners and peers. Work-related issues were highlighted specifically by younger patients, whereas gay and bisexual men emphasised a lack of specialised support.

CONCLUSION

While demonstrating some overarching needs common to most patients with prostate cancer, this review offers novel insight into the unique experiences and needs of men of different demographic backgrounds, which will enable clinicians to deliver individually tailored supportive care.

Barriers and facilitators related to undertaking physical activities among men with prostate cancer: a scoping review

BACKGROUND

Prostate cancer (PC) and its treatments lead to significant acute, chronic, or latent adverse effects that result in declines in patients' physical functions, quality of life and reduced sense of masculinities. Robust evidence shows that physical activity (PA) can improve many health outcomes in men with PC; however, less is known about the facilitators, preferences, and barriers to PA engagement in this population. The purpose of this scoping review is to document the nature and extent of literature related to these aspects of PA participation among men with PC.

METHODS

We conducted a scoping review of PA among men with PC. Databases searched included Medline, CINAHL, Embase, Rehabilitation & Sports Medicine Source, and SportDiscus from inception to June 30, 2020. Multiple reviewers were used in all screening and data abstractions.

RESULTS

The search yielded 2788 individual citations after duplicates were removed. Following title and abstract screening, 129 underwent full-text review, and 46 articles were included. Quantitative data related to our research question showed that structured group exercise was the most commonly reported facilitator/preference among men with PC, whereas treatment-related effects and lack of time are the most common barriers. In terms of qualitative data, the most prominent theme noted related to masculinities and gender-specific needs within the context of having PC.

CONCLUSION

Men with PC have unique facilitators and barriers concerning PA. More work is needed from the research and clinical practice perspectives to enable this population to engage and remain in regular PA.

Acceptability of a Mobile Health Behavior Change Intervention for Cancer Survivors With Obesity or Overweight: Nested Mixed Methods Study Within a Randomized Controlled Trial

Background

A significant proportion of cancer survivors have overweight or obesity. Although this has negative implications for health, weight management is not a standard component of oncology aftercare. Mobile health (mHealth) technology, in combination with behavior change techniques (BCTs), has the potential to support positive lifestyle changes. Few studies have been carried out with cancer survivors; therefore, the acceptability of these tools and techniques requires further investigation.

Objective

The aim of this study is to examine the acceptability of a behavior change intervention using mHealth for cancer survivors with a BMI of 25 or more and to gather constructive feedback from participants.

Methods

The intervention consisted of educational sessions and an 8-week physical activity goal setting intervention delivered using mobile technology (ie, Fitbit activity monitor plus SMS contact). In the context of a two-arm randomized controlled trial, semistructured interviews were conducted to assess the retrospective acceptability of the intervention from the perspective of the recipients. The theoretical framework for the acceptability of health care interventions was used to inform a topic guide. The interviews were transcribed and analyzed using thematic analysis. A quantitative survey was also conducted to determine the acceptability of the intervention. A total of 13 participants were interviewed, and 36 participants completed the quantitative survey.

Results

The results strongly support the acceptability of the intervention. The majority of the survey respondents held a positive attitude toward the intervention (35/36, 97%). In qualitative reports, many of the intervention components were enjoyed and the mHealth components (ie, Fitbit and goal setting through text message contact) were rated especially positively. Responses were mixed as to whether the burden of participating in the intervention was high (6/36, 17%) or low (5/36, 14%). Participants perceived the intervention as having high efficacy in improving health and well-being (34/36, 94%). Most respondents said that they understood how the intervention works (35/36, 97%), and qualitative data show that participants’ understanding of the aim of the intervention was broader than weight management and focused more on moving on psychologically from cancer.

Conclusions

On the basis of the coherence of responses with theorized aspects of intervention acceptability, we are confident that this intervention using mHealth and BCTs is acceptable to cancer survivors with obesity or overweight. Participants made several recommendations concerning the additional provision of social support. Future studies are needed to assess the feasibility of delivery in clinical practice and the acceptability of the intervention to those delivering the intervention.

Experiences of people with cancer who have participated in a hospital-based exercise program: a qualitative study

PURPOSE

Exercise interventions for people with cancer and cancer survivors improve physical health, fatigue, and quality of life. Despite these benefits, poor adherence to exercise is an ongoing challenge among this population. In order to improve adherence in clinical services, this study aims to explore the benefits, challenges, barriers, and facilitators experienced by people with cancer and cancer survivors who participated in a hospital-based exercise program, specifically those who completed or did not complete the full program.

METHODS

This study involved a qualitative approach. People with a cancer diagnosis who did complete (completers, n = 11) and did not complete (non-completers, n = 4) a 12-session exercise program at a tertiary hospital were recruited. Semi-structured interviews were conducted and thematic analysis was employed to identify emergent themes.

RESULTS

Perceived benefits of exercise was the most prominent theme to emerge, with most participants recognizing improvements in physical, mental, and/or social well-being. Non-completers focused on treatment-related side effects, whereas completers saw an opportunity to return to a healthy lifestyle. The transition from a supervised environment to everyday life presented as the most significant barrier to exercise beyond the program among both program completers and non-completers.

CONCLUSIONS

Most people with cancer identified physical, mental, and social benefits from exercising. However, people with cancer and cancer survivors had difficulty maintaining exercise participation beyond completion of a supervised hospital-based program.

IMPLICATIONS

Improving exercise participation in people with cancer and cancer survivors may require supervised exercise interventions plus the implementation of strategies to manage side effects and to facilitate the transition of exercise into everyday life to enhance long-term adherence.

Exploring Social Ecological Determinants of Physical Activity Among Adult Survivors of Childhood Cancer

Purpose: Adult survivors of childhood cancer (ASCCs) are at high risk for cardiovascular disease from chemotherapy- and radiation therapy-related cardiotoxicity. Physical activity (PA) can reduce this risk, but the majority of ASCCs do not engage in sufficient PA. The purpose of this study was to identify barriers, facilitators, and resources for PA among ASCCs using the ecological model of physical activity (EMPA) as a theoretical framework. Methods: A concept elicitation survey was distributed independently to ASCCs (diagnosed with cancer before the age of 18, and currently 18-39 years old) and parents/legal guardians of an ASCC. The survey consisted of open-ended questions asking about barriers, facilitators, and resources for PA. Content analysis of open-ended questions categorized responses into levels of the EMPA and identified key themes. Results: Seventeen ASCCs and eight parents of ASCCs completed the survey. The majority of barriers, facilitators, and resources reported were at the individual and microsystem level of the EMPA. Six themes emerged, suggesting that ASCC's PA was related to proximity/access, social support, equipment, time/schedule, finances, and health-related barriers. Conclusion: This is the first study to examine barriers, facilitators, and resources of PA among ASCCs using the EMPA. Findings from this study provide a multilevel perspective on the influences of PA among ASCCs, and can be used for future, in-depth qualitative studies and quantitative survey development, and as a foundational step toward supportive efforts in increasing PA among ASCCs.

Motivators and barriers to adoption of a healthy diet by survivors of stomach cancer: A cross-sectional study

PURPOSE

This study aimed to identify motivators and barriers to adopting a high-quality diet by survivors of stomach cancer.

BACKGROUND

Despite the benefits of a healthy diet and cancer survivors' motivation to stay healthy, few cancer survivors meet commonly prescribed dietary guidelines, and there have been few studies on the adequacy of dietary management in gastric cancer survivors.

METHODS

This cross-sectional study enrolled 124 adult survivors of stomach cancer. All patients were consecutively recruited from a single tertiary university hospital in South Korea from December 2015 to July 2016. Diet quality was assessed from patients' food diary data on 3 non-consecutive days. The barriers and motivators to following the dietary plan were measured using questionnaires.

RESULTS

Patients were more likely to consume amounts of carbohydrates if they perceived the presence of family and social support and personal disease control. Patients were more likely to consume appropriate carbohydrates and fats, and to have an appropriate intake of calcium if they perceived difficulties in eating with others. Patients were less likely to consume appropriate calcium if they perceived personal limits in their knowledge of shopping and cooking.

CONCLUSION

When caring for stomach cancer survivors, interventions that target patient-perceived barriers and motivators are likely to improve diet quality and lead to beneficial long-term improvements in health.

Cross-sectional study of patient-reported fatigue, physical activity and cardiovascular status in men after robotic-assisted radical prostatectomy

Purpose

Patient-reported fatigue after robotic-assisted radical prostatectomy (RARP) has not been characterised to date. Fatigue after other prostate cancer (PCa) treatments is known to impact on patient-reported quality of life. The aim of this study was to characterise fatigue, physical activity levels and cardiovascular status post-RARP.

Methods

Between October 2016 and March 2017, men post-RARP or on androgen deprivation therapy (ADT) were invited into the study. Participants were asked to complete the Brief Fatigue Inventory (BFI) and Stage of Change and Scottish Physical Activity Questionnaires (SPAQ) over a 2-week period. Outcome measures were patient-reported fatigue, physical activity levels and the 10-year risk of cardiovascular disease (Q-Risk). Data were analysed in SPSS.

Results

96/117 (82%) men approached consented to participate; of these, 62/96 (65%) returned complete questionnaire data (RARP n = 42, ADT n = 20). All men reported fatigue with 9/42 (21%) post-RARP reporting clinically significant fatigue. Physical activity did not correlate with fatigue. On average, both groups were overweight (BMI 27.0 ± 3.9 kg/m² and 27.8 ± 12.3 kg/m² for RARP and ADT, respectively) and the post-RARP group had an 18.1% ± 7.4% Q-Risk2 score.

Conclusions

A proportion of men is at increased risk of cardiovascular disease within 10 years post-RARP and have substantial levels of fatigue; therefore, clinicians should consider including these factors when counselling patients about RARP. Additionally, men post-RARP did not meet the recommended guidelines for resistance-based exercise. Future research is needed to establish whether interventions including resistance-based exercise can improve health and fatigue levels in this population.

ProDiet: A Phase II Randomized Placebo-controlled Trial of Green Tea Catechins and Lycopene in Men at Increased Risk of Prostate Cancer

Epidemiologic studies suggest that diet can alter prostate cancer risk. This study aimed to establish the feasibility and acceptability of dietary modification in men at increased risk of prostate cancer. Men were invited with a PSA level of 2.0-2.95 ng/mL or 3.0-19.95 ng/mL with negative prostate biopsies. Randomization (3 × 3 factorial design) to daily green tea and lycopene: green tea drink (3 cups, unblinded) or capsules [blinded, 600 mg flavan-3-ol ()-epigallocatechin-3-gallate (EGCG) or placebo] and lycopene-rich foods (unblinded) or capsules (blinded, 15 mg lycopene or placebo) for 6 months. Primary endpoints were randomization rates and intervention adherence (blinded assessment of metabolites) at 6 months with secondary endpoints of acceptability (from interviews), safety, weight, blood pressure, and PSA. A total of 133 of 469 (28.4%) men approached agreed to be randomized and 132 were followed-up (99.2%). Mean lycopene was 1.28 [95% confidence intervals (CI), 1.09-1.50, P = 0.003] times higher in the lycopene capsule group and 1.42 (95% CI, 1.21-1.66; P < 0.001) times higher in the lycopene-enriched diet group compared with placebo capsules. Median EGCG was 10.7 nmol/L (95% CI, 7.0-32.0) higher in in the active capsule group and 20.0 nmol/L (95% CI, 0.0-19.0) higher in the green tea drink group compared with placebo capsules (both P < 0.001). All interventions were acceptable and well tolerated although men preferred the capsules. Dietary prevention is acceptable to men at risk of prostate cancer. This intervention trial demonstrates that a chemoprevention clinical trial is feasible. Cancer Prev Res; 11(11); 687-96. ©2018 AACR.
