RESUMO
INTRODUCTION: Sarcopenia is a predictor of clinical outcomes in men with metastatic castrate-resistant prostate cancer (mCRPC); however, correlates and predictors of sarcopenia are poorly understood in this population. The aim of this study was to examine correlates and predictors of sarcopenia in men with mCRPC prior to treatment. METHODS: A secondary analysis of an observational study was performed. Participants were receiving care for mCRPC at the Princess Margaret Cancer Centre. Sarcopenia was assessed prior to treatment and was defined as the combination of low grip strength (<35.5 kg), low gait speed (<0.8 m/s), and computed tomography-derived low muscle mass or density. Participants' sociodemographic and clinical characteristics, comorbidity information, and clinically relevant blood markers were collected prior to treatment and were used to identify correlates and predictors of sarcopenia through Spearman correlations and multivariable logistic regression, respectively. RESULTS: In total, 110 men had complete data on sarcopenia measures and were included in the analysis. Sarcopenia was identified in 30 (27.3%) participants. Pre-treatment sarcopenia was moderately correlated with dependence in one or more instrumental activities of daily living (IADLs) (r=0.412), Vulnerable Elders Survey-13 (r=0.404), and a lower hemoglobin (r=0.407 per 10 g/L decrease). In adjusted logistic regression, dependence in one or more IADLs (odds ratio [OR] 4.37, 95% confidence interval [CI] 1.37-13.86, p=0.012), and a 10 g/L decrease in hemoglobin (OR 1.70, 95% CI 1.13-2.57, p=0.012) were significantly associated with sarcopenia. CONCLUSIONS: In settings where assessment of sarcopenia is not feasible, evaluation of IADLs and hemoglobin may be used to identify high-risk patients that can benefit from supportive care strategies aiming to improve muscle mass and function.
RESUMO
Older adults with cancer often present with distinct complexities that complicate their care, yet the language used to discuss their management at multidisciplinary cancer conferences (MCCs) remains poorly understood. A mixed methods study was conducted at a tertiary cancer centre in Toronto, Canada, where MCCs spanning five tumour sites were attended over six months. For presentations pertaining to a patient aged 75 or older, a standardized data collection form was used to record their demographic, cancer-related, and non-cancer-related information, as well as the presenter's specialty and training level. Descriptive statistics and thematic analysis were employed to explore MCC depictions of older patients (n = 75). Frailty status was explicitly mentioned in 20.0% of presentations, but discussions more frequently referenced comorbidity burden (50.7%), age (33.3%), and projected treatment tolerance (30.7%) as surrogate measures. None of the presentations included mentions of formal geriatric assessment (GA) or validated frailty tools; instead, presenters tended to feature select GA domains and subjective descriptions of appearance ("looks to be fit") or overall health ("relatively healthy"). In general, MCCs appeared to rely on age-focused language that may perpetuate ageism. Further work is needed to investigate how frailty and geriatric considerations can be objectively incorporated into discussions in geriatric oncology.
RESUMO
INTRODUCTION: Current management of metastatic prostate cancer (mPC) includes androgen receptor axis-targeted therapy (ARATs), which is associated with substantial toxicity in older adults. Geriatric assessment and management and remote symptom monitoring have been shown to reduce toxicity and improve quality of life in patients undergoing chemotherapy, but their efficacy in patients being treated with ARATs has not been explored. The purpose of this study is to examine whether these interventions, alone or in combination, can improve treatment tolerability and quality of life (QOL) for older adults with metastatic prostate cancer on ARATs. MATERIALS AND METHODS: TOPCOP3 is a multi-centre, factorial pilot clinical trial coupled with an embedded process evaluation. The study includes four treatment arms: geriatric assessment and management (GA + M); remote symptom monitoring (RSM); geriatric assessment and management plus remote symptom monitoring; and usual care and will be followed for six months. The aim is to recruit 168 patients between two cancer centres in Toronto, Canada. Eligible participants will be randomized equally via REDCap. Participants in all arms will complete a comprehensive baseline assessment upon enrollment following the Geriatric Core dataset, as well as follow-up assessments at 1.5, 3, 4.5, and 6 months. The co-primary outcomes will be grade 3-5 toxicity and QOL. Toxicities will be graded using the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. QOL will be measured by patient self-reporting using the EuroQol 5 dimensions of health questionnaire. Secondary outcomes include fatigue, insomnia, and depression. Finally, four process evaluation outcomes will also be observed, namely feasibility, fidelity, and acceptability, along with implementation barriers and facilitators. DISCUSSION: Data will be collected to observe the effects of GA + M and RSM on QOL and toxicities experienced by older adults receiving ARATs for metastatic prostate cancer. Data will also be collected to help the design and conduct of a definitive multicentre phase III randomized controlled trial. This study will extend supportive care interventions for older adults with cancer into new areas and inform the design of larger trials. TRIAL REGISTRATION: The trial is registered at clinicaltrials.gov (registration number: NCT05582772).

INTRODUCTION: Differences between health outcomes, participation/adoption, and cost-effectiveness of home-based (HOME) interventions and supervised group-based training (GROUP) in men with prostate cancer (PC) on androgen deprivation therapy (ADT) are currently unknown. The objective of this study was to assess the clinical efficacy, adherence, and cost-effectiveness of HOME versus GROUP in men on ADT for PC. MATERIALS AND METHODS: This was a multicentre, 2-arm non-inferiority randomized controlled trial and companion cost-effectiveness analysis. Men with PC on ADT were recruited from August 2016 to March 2020 from four Canadian centres and randomized 1:1 to GROUP or HOME. All study participants engaged in aerobic and resistance training four to five days weekly for six months. Fatigue [Functional Assessment of Cancer Therapy-Fatigue (FACT-F)] and functional endurance [6-min walk test (6MWT)] at six months were the co-primary outcomes. Secondary outcomes included quality of life, physical fitness, body composition, blood markers, sedentary behaviour, and adherence. Between-group differences in primary outcomes were compared to margins of 3 points for FACT-F and 40 m for 6MWT using a Bayesian analysis of covariance (ANCOVA). Secondary outcomes were compared with ANCOVA, Costs included Ministry of Health costs, program costs, patient out-of-pocket, and time costs. TRIAL REGISTRATION: #NCT02834416. RESULTS: Thirty-eight participants (mean [standard deviation (SD)] age, 70 [9.0] years) were enrolled (GROUP n = 20; HOME n = 18). There was an 89.8% probability that HOME was non-inferior to GROUP for both fatigue and functional endurance and a 9.5% probability that HOME reduced fatigue compared to GROUP (mean [SD] change, 12.1 [8.1] vs 3.6 [6.1]; p = 0.040) at six months. Adherence was similar among study arms. HOME was cost-saving (mean difference: -$4122) relative to GROUP. DISCUSSION: A HOME exercise intervention appears non-inferior to GROUP for fatigue and functional endurance and requires fewer resources to implement. HOME appears to ameliorate fatigue more than GROUP, but has comparable effects on other clinically relevant outcomes. Although limited by sample size and attrition, these results support further assessment of home-based programs.

INTRODUCTION: Sarcopenia is common in men with metastatic castrate-resistant prostate cancer (mCRPC) and has been largely assessed opportunistically through computed-tomography (CT) scans, excluding measures of muscle function. Therefore, the impact of a comprehensive assessment of sarcopenia on clinical outcomes in men with mCRPC is poorly understood. The objectives of this study were to comprehensively assess sarcopenia through CT scans and measures of muscle function and examine its impact on severe treatment toxicity, time to first emergency room (ER) visit, disease progression, and overall mortality in men initiating chemotherapy or androgen receptor-targeted axis (ARAT) therapy for mCRPC. METHODS: This was a secondary analysis of a prospective observational study of men with mCRPC at the Princess Margaret Cancer Centre between July 2015-May 2021. Participants were classified as sarcopenic if they had CT-based low muscle mass or low muscle density, a grip strength and gait speed score of <35.5kg and <0.8m/s, respectively, prior to treatment initiation. The impact of sarcopenia on severe treatment toxicity was assessed using multivariable logistic regression. Multivariable Cox regression models were used to determine the impact of sarcopenia on risk of visiting the ER, prostate-specific antigen progression, radiographic progression, and overall mortality. RESULTS: A total of 110 men (mean age: 74.6) were included in the analysis. At baseline, 30 (27.3%) were classified as sarcopenic. Sarcopenia was a significant predictor of severe toxicity (aOR = 6.26, 95%CI = 1.17-33.58, P = 0.032) and ER visits (aHR = 4.41, 95%CI = 1.26-15.43, p = 0.020) in men initiating ARAT but not in men initiating chemotherapy. Sarcopenia was also a predictor of radiographic progression (aHR = 2.39, 95%CI = 1.06-5.36, p = 0.035) and overall mortality (aHR = 2.44, 95%CI = 1.17-5.08, p = 0.018) regardless of treatment type. CONCLUSIONS: Baseline sarcopenia predicts radiographic progression and overall mortality in men with mCRPC regardless of the type of treatment and may also predict severe treatment toxicity and ER visits in men initiating ARAT.

INTRODUCTION: Remote, online geriatric assessment (GA) is gaining attention in oncology. Most GA domains can be assessed remotely. However, there is limited evidence identifying reliable tools that can be used in lieu of objective measures of physical function, such as grip strength and physical performance during remote, online GA. In this prospective cohort study, we aimed to assess the performance of the SARC-F, a screening questionnaire for sarcopenia, in identifying low grip strength and the Short Physical Performance Battery (SPPB). Additionally, we assessed the satisfaction of clinical staff with using the SARC-F in the clinic. MATERIALS AND METHODS: Data were prospectively collected from older adults with cancer of any type and stage who underwent GA in the geriatric oncology clinic of a tertiary cancer centre. Following GA, patients were asked to complete the SARC-F tool. Spearman correlations were performed between objective measures of physical function, SARC-F domains, and SARC-F total score. Additionally, the sensitivity, specificity, positive predictive value, and negative predictive value were assessed to evaluate the performance of SARC-F to detect low grip strength and SPPB. RESULTS: Eighty (n = 80) older adults (mean age: 80 years) with cancer completed the SARC-F. A positive SARC-F was found in 31.3% of the cohort. Moderate correlations were found between the SPPB per point and Assistance in walking (r = -0.69), as well as the SPPB per point and total SARC-F score (r = -0.66). SARC-F exhibited moderate sensitivity in identifying low grip strength using the Foundation for the National Institutes of Health (FNIH) criteria (sensitivity: 64.3%) or the Sarcopenia Definitions and Outcomes Consortium (SDOC) criteria (sensitivity: 40.4%). However, specificity was high (>75%) regardless of the criteria applied. Similarly, moderate sensitivity (52.2%), but excellent specificity (97.1%) was found for SPPB. When low grip strength per FNIH was combined with low SPPB, SARC-F demonstrated high sensitivity (80%) and specificity (75.7%). DISCUSSION: SARC-F exhibited promising performance in identifying low grip strength per FNIH and low SPPB combined. To definitively assess the performance of the SARC-F in detecting low grip strength and SPPB, larger studies are warranted.

INTRODUCTION: Low physical function is associated with adverse outcomes in older adults with cancer, but evidence on real-world, clinical management of low physical function in oncology is lacking. We explored whether impairments in muscle strength and/or physical performance triggered downstream management by clinicians, the types of recommended strategies, and the reasons for not providing a referral/strategy for addressing such impairments in older cancer survivors prior to treatment. MATERIALS AND METHODS: We conducted a retrospective, cross-sectional study of older adults who completed a comprehensive geriatric assessment (CGA) prior to cancer treatment in a tertiary cancer centre. Muscle strength and physical performance were assessed through grip strength and the Short Physical Performance Battery (SPPB), respectively. Patients who exhibited an impairment in grip strength and/or SPPB were classified as having abnormal objective physical function. Downstream management strategies and clinicians' reasons for not providing referrals were retrieved from clinical notes and an institutional database. RESULTS: In total, 515 older adults (mean age: 80.7 years) were included. Low grip strength and/or SPPB combined was observed in 66.4% (n = 342) of participants, of whom 54.1% (n = 185) received an acceptable intervention. However, 41.2% (n = 141) were not provided with a referral/strategy by clinicians to address such impairments following CGA. No reasons were provided in clinical notes for not addressing impairments in physical function for 100 participants (70.9%). DISCUSSION: Many older adults with cancer have impaired physical function prior to treatment. However, we found that such impairments are not systematically addressed by clinicians, and documentation was often suboptimal, identifying gaps in patient care that need to be addressed.

INTRODUCTION: Geriatric assessment (GA) provides information on key health domains of older adults and is recommended to help inform cancer treatment decisions and cancer care. However, GA is not feasible in many health institutions due to lack of geriatric staff and/or resources. To increase accessibility to GA and improve treatment decision making for older adults with cancer (≥65 years), we developed a self-reported, electronic geriatric assessment tool: Comprehensive Assessment for My Plan (CHAMP). MATERIALS AND METHODS: Older adults with cancer were invited to join user-centered design sessions to develop the layout and content of the tool. Subsequently, they participated in usability testing to test the usability of the tool (ease of use, acceptability, etc.). Design sessions were also conducted with oncology clinicians (oncologists and nurses) to develop the tool's clinician interface. GA assessment questions and GA recommendations were guided by a systematic review and Delphi expert panel. RESULTS: A total of seventeen older adults participated in the study. Participants were mainly males (82.4%) and 75% were aged 75 years and older. Nine oncology clinicians participated in design sessions. Older adults and clinicians agreed that the tool was user-friendly. Domains in the final CHAMP tool (with questions and recommendations) included functional status, falls risk, cognitive impairment, nutrition, medication review, social supports, depression, substance use disorder, and miscellaneous items. DISCUSSION: CHAMP was designed for use by older adults and oncologists and may enhance access to GA for older adults with cancer. The next phase of the CHAMP study will involve field validation in oncology clinics.

Introduction: Patients' unwillingness to be randomized to a mode of exercise may partly explain their poor recruitment, adherence, and attrition in randomized controlled trials (RCTs) of exercise in oncology. It is unknown whether a preference-based trial can improve recruitment, adherence, retention, and clinical outcomes compared to a RCT of the same exercise interventions. Objective: We assessed the effects of a 2-arm exercise preference trial on adherence and clinical outcomes compared to a similar 2-arm RCT in men with prostate cancer (PC). Methods: This was a two-arm preference-based trial of group-based training (GROUP) or home-based training (HOME). PC survivors on androgen deprivation therapy (ADT) who declined randomization to the RCT but chose to participate in a preference trial were recruited in four Canadian centers. All study participants engaged in aerobic and resistance training, 4-5 days weekly for 6 months, aiming for 150 minutes/week of moderate-to-vigorous physical activity. The primary outcomes were changes from baseline to 6 months in fatigue and functional endurance. Secondary outcomes were quality of life, physical fitness, body composition, blood markers, and adherence. Linear mixed models were used to assess the effects of HOME versus GROUP on primary outcomes. In pooled preference and RCT data, the selection effect (i.e., difference between those who were and were not willing to be randomized) and treatment effect (i.e., difference between GROUP and HOME) were estimated using linear regression. Results and conclusion: Fifty-four participants (mean [SD] age, 70.2 [8.6] years) were enrolled (GROUP n=17; HOME n=37). Comparable effects on primary and secondary outcomes were observed following GROUP or HOME in the preference-based trial. Adherence was similar between preference and RCT participants. However, attrition was higher in the RCT (50.0% vs. 27.8%, p= 0.04). Compared to GROUP, HOME was more effective in ameliorating fatigue (mean difference: +5.2, 95%CI=1.3 to 9.3 p=0.01) in pooled preference and RCT data. A preference-based trial results in comparable observed effects on clinical outcomes and adherence and lower attrition compared with a RCT of the same exercise interventions in PC survivors on ADT. Given the appeals of preference-based trials to study participants, additional studies are warranted. Clinical trial registration: clinicaltrials.gov, identifier (NCT03335631).
RESUMO
BACKGROUND: Lactate dehydrogenase (LDH) reflects tumor burden and is a prognosticator of all-cause mortality in patients with cancer. Objective measures of physical function are associated with clinically relevant outcomes in older adults with cancer. However, whether physical function is associated with LDH in geriatric oncology is unknown. The objective of this study was to assess the relationship between objective measures of physical function and serum LDH in older adults with cancer prior to treatment. METHODS: Data from older adults with cancer prior to treatment were retrieved from an institutional database and medical records within a tertiary cancer centre. Physical function measures involved muscle strength and physical performance. Muscle strength and physical performance were assessed through grip strength and the Short Physical Performance Battery (SPPB), respectively. LDH was log transformed using the natural logarithm. Multivariable logistic regression was used to examine the relationship between objective measures of physical function and LDH prior to treatment in all participants. Stratified analyses were performed for participants with solid and hematological cancers. RESULTS: A total of 257 participants (mean age: 80.2y) were included in the analysis. Most participants were females (50.6%) and were diagnosed with locally advanced (26.8%), gastrointestinal disease (35.0%). The multivariable analysis indicated that SPPB was inversely associated with LDH in all participants (B = -0.019, 95%CI = -0.036 to -0.002, p = 0.028). Notably, the inverse relationship between SPPB and LDH persisted only in patients with hematological malignancies in the multivariable model of the stratified analysis (B = -0.049, 95%CI = -0.087 to -0.011, p = 0.013). Neither grip strength alone nor the combination of low grip strength and/or SPPB were associated with LDH. Compared to participants with metastatic disease, those with localized or locally advanced disease had lower serum LDH. CONCLUSION: Physical performance is inversely associated with serum LDH in older adults with hematological cancers prior to treatment.

BACKGROUND: Whether individual, environmental, and psychosocial factors predict changes in moderate-to-vigorous physical activity (MVPA) is poorly addressed in prostate cancer (PC) survivors undergoing androgen deprivation therapy (ADT). PURPOSE: This secondary analysis of a randomized controlled trial examined changes in MVPA following a supervised personal training (PT), supervised group-based (GROUP) program, or a home-based, smartphone-assisted exercise (HOME) intervention in PC survivors on ADT and explored individual, environmental, and psychosocial predictors of MVPA. METHODS: PC survivors on ADT underwent aerobic and resistance training for 6 months via PT, GROUP, or HOME. MVPA was captured via accelerometers and the Godin Leisure-Time Exercise Questionnaire. Changes in MVPA between groups were assessed using linear regression. The following predictors of MVPA were examined using Spearman correlations: the Neighborhood Environment Walkability Scale (NEWS); the Planning, Attitudes, and Behaviours (PAB) scale; the Relatedness to Others in Physical Activity Scale (ROPAS); and individual factors at baseline. RESULTS: Participants (n = 37) were 69.4 ± 6.5 years old and 78.4% were on ADT for ≥ 3 months. Changes in accelerometry-based bouts and MVPA as well as self-reported MVPA did not differ between groups at 6 months. The Aesthetics domain of the NEWS questionnaire at baseline was the strongest predictor of positive MVPA changes (r = .66). Attitude (r = .64), planning (r = .57), and motivation (r = .50) at baseline were also predictive of engaging in higher MVPA throughout the intervention. CONCLUSION: Changes in objective MVPA were modest. Additional emphasis on specific psychosocial and individual factors is important to inform theory-based interventions that can foster PA behavior change in PC survivors on ADT. Registration # NCT02046837.

INTRODUCTION: Objective measures of physical function are associated with cognitive function in community-dwelling older adults. Many older adults experience cognitive declines prior to cancer treatment initiation. Thus, it is unclear whether the association between low physical function and cognitive impairment is generalizable to older adults with cancer prior to treatment. Our objective was to examine whether objective measures of physical function were associated with cognitive impairment in geriatric oncology patients prior to treatment. MATERIALS AND METHODS: We used prospectively collected data from an institutional database within a cancer centre and electronic medical records of older adults who had undergone a geriatric assessment before cancer treatment. Objective measures of physical function included grip strength and the Short Physical Performance Battery (SPPB). Cognitive impairment was assessed via the Mini-Cog. Multivariable logistic regression was used to determine whether grip strength and SPPB were associated with cognitive impairment prior to cancer treatment in all patients, as well as in patients with moderate-to-high comorbidity as part of a sensitivity analysis. RESULTS: A total of 386 older adults (mean age 80.9 years) were included in the analysis. Most participants (65.3%) had low grip strength and/or low SPPB, whereas 42.2% were cognitively impaired. Neither low grip strength (odds ratio [OR] = 1.55, 95% confidence interval [CI] = 0.92-2.63, p = 0.097) nor low SPPB (OR = 1.29, 95%CI = 0.69-2.42, p = 0.41) alone or combined (OR = 1.05, 95%CI = 0.59-1.88, p = 0.85) were significantly associated with cognitive impairment in multivariable analyses of all patients. However, low SPPB was significantly associated with cognitive impairment in the sensitivity analysis restricted to patients with moderate-to-high comorbidity (OR = 4.05, 95%CI = 1.50-10.95, p = 0.006). Dependence in one or more instrumental activities of daily living [IADLs] was consistently associated with cognitive impairment in the main and sensitivity analyses. DISCUSSION: Low physical performance and IADL dependence are associated with cognitive impairment in patients with moderate-to-high comorbidity prior to cancer treatment. Scrutiny is advised for these patients to assess for possible cognitive impairment. Larger studies are warranted to confirm our findings.

BACKGROUND: Grip strength (GS) and the short physical performance battery (SPPB) have been shown to predict clinical outcomes in older adults with cancer. However, whether pre-treatment GS and SPPB impact treatment decisions following comprehensive geriatric assessment (CGA) is poorly understood. Our objective was to assess the impact of low GS and/or SPPB on treatment modification to initially proposed treatment plans in older adults with cancer following CGA. METHODS: This was a retrospective cohort study of older adults who had undergone CGA before receiving cancer treatment. Data were retrieved from a prospective database in an academic cancer centre and medical records. Treatment modification following CGA was defined as reduced treatment intensity or transition from active treatment to supportive care. Multivariable logistic regression assessed the impact of pre-treatment GS and SPPB on treatment modification following CGA. RESULTS: In total, 515 older adults (mean age: 80.7y) who had undergone CGA prior to cancer treatment were included. Low muscle strength and/or physical performance was observed in 66.4% of participants. Treatment was modified in 49.5% of the cohort following CGA. Low GS and/or SPPB combined was predictive of treatment modification (OR = 1.77, 95%CI = 1.07-2.90, P = 0.025) in multivariable analysis. Additional predictors of treatment modification included palliative treatment intent, comorbidities and malnutrition. CONCLUSIONS: Low GS and/or SPPB combined prior to cancer treatment predicts treatment modification in older adults with cancer and may be useful in treatment decision-making. Management of poor muscle strength and physical performance should be offered to optimize patient care and potentially improve treatment outcomes.

The frailty index (FI) predicts clinical outcomes in oncology. However, in the acute myeloid leukemia (AML) setting, its predictive ability is poorly understood. We assessed whether the FI predicts complete remission (CR), intensive care unit (ICU) admission, and 1-year all-cause mortality in younger and older adults with AML receiving intensity chemotherapy. This was a secondary analysis of a prospective study. In total, 237 patients (n = 140 younger and n = 97 older adults) were classified as non-frail, prefrail, or frail. Frail younger adults were less likely to achieve CR compared with non-frail younger adults. Pre-frail and frail younger adults were more likely to be admitted to the ICU compared with their non-frail counterparts. The FI was not predictive of 1-year all-cause mortality. The FI predicts CR and ICU admission in younger but not older adults. Disease biology may be more important than frailty in predicting 1-year overall mortality in patients with AML undergoing chemotherapy.

BACKGROUND: There are no guidelines available for what assessment tools to use in a patient's self-completed online geriatric assessment (GA) with management recommendations. Therefore, we used a modified Delphi approach with Canadian expert clinicians to develop a consensus online GA plus recommendations tool. METHODS: The panel consisted of experts in geriatrics, oncology, nursing, and pharmacy. Experts were asked to rate the importance and feasibility of assessments and interventions to be included in an online GA for patients. The items included in the first round were based on guidelines for in-person GA and literature review. The first two rounds were conducted using an online survey. A virtual 2 h meeting was held to discuss the items where no consensus was reached and then voted on in the final round. RESULTS: 34 experts were invited, and 32 agreed to participate. In round 1, there were 85 items; in round 2, 50 items; and in round 3, 25 items. The final tool consists of fall history, assistive device use, weight loss, medication review, need help taking medication, social supports, depressive symptoms, self-reported vision and hearing, and current smoking status and alcohol use. CONCLUSION: This first multidisciplinary consensus on online GA will benefit research and clinical care for older adults with cancer.

BACKGROUND: Grip strength (GS) and the Short Physical Performance Battery (SPPB) are brief objective tests used during a comprehensive geriatric assessment (CGA) to assess physical performance. Abnormal GS and SPPB scores are associated with greater morbidity and mortality in older adults with cancer but their relationship with chemotherapy tolerability is unclear. We explored the performance of GS and SPPB in predicting therapy delay, dose reduction, and treatment completion in older adults undergoing chemotherapy or chemoradiation. Additionally, we examined associations between GS, SPPB, and instrumental activities of daily living (IADLs). METHODS: Retrospective review of patients ≥65 years old who had undergone a pre-treatment CGA in a geriatric oncology clinic were retrieved from electronic charts and institutional databases. Abnormal GS was defined as <26 kg and < 16 kg for men and women, respectively. Abnormal SPPB was defined as ≤9 points. Logistic regression was used to examine the associations between abnormal GS or SPPB alone or combined with chemotherapy-related outcomes (e.g., delay, dose reduction, completion). Chi-squared tests were used to determine associations between physical performance measures (GS and SPPB) and IADLs. RESULTS: A total of 85 participants (mean age 79.1 years old) with mixed cancer diagnoses were included. Approximately 67% of participants exhibited abnormal GS or SPPB prior to treatment. Abnormal GS or SPPB (combined) was associated with treatment delay (odds ratio (OR) = 7.58, 95% confidence interval (CI) = 1.77, 32.43, P = 0.006). When physical performance measures were examined separately, only SPPB predicted treatment delay (OR = 3.26, 95%CI = 1.04, 10.21, P = 0.043). Abnormal GS or SPPB were not associated with dose reduction or treatment completion. Abnormal GS and SPPB alone or combined demonstrated only modest sensitivity (41.9-76.7%) and negative predictive value (57.9-64.2%) in identifying IADLs dependence. CONCLUSION: GS and SPPB may be used to predict treatment delay in older adults prior to chemotherapy and chemoradiation. Additional studies are warranted to examine whether GS and/or SPPB can predict dose reduction and treatment completion in older adults prior to receiving chemotherapy or chemoradiation.

BACKGROUND: The relationship between preoperative physical activity (PA) and hospital length of stay (LOS) following radical prostatectomy (RP) is poorly understood. In addition, the relationship between PA and the American Society of Anesthesiologists Physical Status score (ASA PS), an established prognosticator of surgical risk, has not been studied. The authors assessed the relationship between leisure-time PA (LTPA), ASA PS, and LOS in individuals undergoing RP. METHODS: This retrospective cohort study was conducted using data from an institutional database. Ordinal logistic regression was used to assess the relationship between preoperative LTPA and physical status as indicated by the ASA PS. Binary logistic regression was used to assess the relationship between preoperative LTPA and LOS. RESULTS: A sample of 1064 participants were included in the analyses. The participants in the highest preoperative LTPA quartile had 45% reduced odds (P = .015) of a worse ASA PS classification compared with participants in the lowest quartile. The participants engaging in vigorous LTPA preoperatively had 35% lower odds (P = .014) of a >2-day LOS following RP compared with participants who were not engaging in preoperative vigorous LTPA. CONCLUSIONS: Our findings suggest that total and vigorous preoperative LTPA is associated with improved preoperative American Society of Anesthesiologists scores and LOS following RP, respectively.

This study assessed the feasibility of a phase II randomized controlled trial of high-intensity interval training (HIIT), resistance training (RT), and usual care (UC) in men with prostate cancer (PCa) on active surveillance and evaluated changes in clinically relevant outcomes. Eighteen men undergoing active surveillance for PCa were randomized to HIIT (n = 5), RT (n = 7), or UC (n = 6). Exercise participants attended 2 supervised sessions weekly and were instructed to complete 1 home-based session weekly for 8 weeks. UC participants were provided with physical activity guidelines. Feasibility was met for attendance, compliance, and retention, but not recruitment. HIIT increased leg press (mean: +8.2 kg, 95% CI 1.1 to 15.3) from baseline to 8 weeks. RT increased seated row (mean: +11.7 kg, 95% CI 6.1 to 17.3), chest press (mean: +10.4 kg, 95% CI 5.3 to 15.5), leg press (mean: +13.1 kg, 95% CI 5.9 to 20.3), serum insulin-like binding protein-3 (IGFBP-3) (mean: +400.0 ng/mL, 95% CI 94.5 to 705.5), and decreased interferon-γ (mean: -3.1 pg/mL, 95% CI -5.7 to -0.4). No changes were observed in the UC group. HIIT and RT may be effective strategies for improving muscle strength; however, only RT may increase serum IGFBP-3. Strategies that can enhance recruitment in men on active surveillance are important prior to conducting a phase II trial. Trial registration number: ClinicalTrials.gov number NCT04266262. Novelty: High-intensity interval training or resistance training are feasible during active surveillance for prostate cancer. Resistance training may suppress the tumour-promoting effects of insulin-like growth factor-I (IGF-I) via increased expression of IGFBP-3.

OBJECTIVE: The relationship between physical activity (PA) and quality of life (QOL) relative to active treatment for prostate cancer (PCa) has been well-studied; however, little is known about this relationship during active surveillance (AS). Moreover, whether PA is associated with better emotional well-being (EWB) in men with low-risk PCa requires further investigation. Accordingly, we examined the association between self-reported PA and the average change in QOL and EWB over time during AS. METHODS: A total of 630 men on AS were included in this retrospective, longitudinal study from AS initiation until AS discontinuation. Generalized estimated equations were used to determine the association between self-reported PA (independent variable) and QOL and EWB (dependent variables) over time, adjusting for participants' age. RESULTS: QOL was higher over time in active ( ß^ (95%CI) = 1.14 (0.11, 2.16), P = .029) and highly active participants ( ß^ (95%CI) = 1.62 (0.58, 2.67), P = .002) compared to their inactive counterparts. Highly active participants had 55% greater odds of experiencing high EWB relative to inactive participants (OR (95%CI) = 1.55 (1.11, 2.16), P = .010). In men with low EWB at baseline (median = 3 months after diagnosis), the highest levels of PA (>1000 metabolic equivalent-minutes per week) were associated with high EWB over time (OR (95%CI) = 2.17 (1.06, 4.46), P = .034). CONCLUSIONS: These data further support the importance of PA as a supportive care strategy for men on AS. Our findings suggest that engaging in higher volumes of PA post-diagnosis may be beneficial particularly for men exhibiting low emotional well-being early on during AS.
