(1) Background: Adolescents and young adults (AYAs) who have been diagnosed with and treated for cancer have unique healthcare needs, but more research is needed to inform developmentally targeted cancer care for this population. The purpose of the current analyses was to describe the physical and psychosocial concerns and experiences of AYA cancer survivors during the post-treatment phase. (2) Methods: A national survey was conducted by the Canadian Partnership Against Cancer to evaluate the experiences and unmet needs of cancer survivors (≥18 years) within the first 5 years following cancer treatment. The current analyses were conducted on the AYA survivor population (18–34 years). (3) Results: A total of 575 surveys were completed by AYAs. Of these, 61% were female, 51% were married/partnered, and 52% were 1–3 years post treatment. Approximately three-quarters report their physical or emotional health as good/very good. Overall, 88% reported at least one physical concern [mean of 3.98+2.11 physical concerns (range 0–9)], 90% reported at least one emotional concern [mean of 3.77+1.75 emotional concern (range 0–6)], and 79% reported at least one practical challenge [mean of 2.39+1.28 practical concerns (range 0–5)]. The most common concerns were anxiety/worry about cancer returning (83%), fatigue/tiredness (78%), and depression/loss of interest in daily activities (66%). On average, 43% of those reporting a concern sought help. Common reasons for not seeking help included not wanting to ask, being told that it was normal to feel the way they did, or embarrassment. Of those who did seek help, 37% encountered difficulty obtaining assistance. (4) Conclusions: These results suggest that post-treatment AYA cancer survivors have a high rate and number of physical, psychosocial, and practical concerns and are often not seeking or receiving help to address these. Proactive approaches to characterizing and eliminating barriers to obtaining appropriate care are needed.

Given the high levels of sedentary time and treatment-related side effects in prostate cancer survivors (PCS), interventions targeting sedentary behavior (SED) may be more sustainable compared to physical activity (PA). To examine the feasibility of a web-based intervention (RiseTx) for reducing SED and increasing moderate-to-vigorous physical activity (MVPA) among PCS undergoing ADT. Secondary outcomes include changes in SED, MVPA, light intensity PA, and quality of life. Forty-six PCS were recruited from two cancer centres in Toronto, Ontario, Canada between July 2015–October 2016. PCS were given an activity tracker (Jawbone), access to the RiseTx website program, and provided with a goal of increasing walking by 3000 daily steps above baseline levels over a 12-week period. A range of support tools were progressively released to reduce SED time (e.g., self-monitoring of steps) during the five-phase program. Objective measures of SED, MVPA, and daily steps were compared across the 12-week intervention using linear mixed models. Of the 46 PCS enrolled in the study, 42 completed the SED intervention, representing a 9% attrition rate. Measurement completion rates were 97 and 65% at immediately post-intervention and 12-week follow-up for all measures, respectively. Overall adherence was 64% for total number of logins (i.e., > 3 visits each week). Sample mean age was 73.2 ± 7.3 years, mean BMI was 28.0 ± 3.0 kg/m2, mean number of months since diagnosis was 93.6 ± 71.2, and 72% had ADT administered continuously. Significant reductions of 455.4 weekly minutes of SED time were observed at post-intervention (p = .005). Significant increases of + 44.1 for weekly minutes of MVPA was observed at immediately post-intervention (p = .010). There were significant increases in step counts of + 1535 steps from baseline to post-intervention (p < .001). RiseTx was successful in reducing SED and increasing MVPA in PCS. PCS were satisfied with the intervention and its components. Additional strategies may be needed though for maintenance of behavior change. The next step for RiseTx is to replicate these findings in a larger, randomized controlled trial that will have the potential for reducing sedentary time among PCS.

People with cancer who undergo allogeneic hematological stem cell transplant (allo-HSCT) experience significant deconditioning that can compromise quality of life. Exercise has shown to be beneficial before or after allo-HSCT; however, little is known about exercise therapy delivered across the continuum of care. We conducted a feasibility randomized controlled trial of exercise delivered prior to admission, during the inpatient stay, and after discharge versus control in people with planned allo-HSCT. Feasibility was assessed via recruitment and retention rates, the incidence of adverse events, and adherence to the exercise prescription. Estimates of efficacy were measured at baseline, one week prior to hospital admission, and 100 days and one year after transplant. The recruitment and retention rates were 20% and 33%, respectively. One serious adverse event occurred during the baseline six-minute walk test that precluded participation in the study and no adverse events were associated with the intervention. From baseline to pre-transplant, the intervention group improved six-minute walk test distances by 45 m (95% CI: −18.0 to 108.7)—a finding that warrants further investigation with an adequately powered trial. Our study contributes important feasibility considerations and pilot data for future exercise intervention research in allo-HSCT recipients.

Background: Although facility-based cancer rehabilitation and exercise programs exist, patients are often unable to attend due to distance, cost, and other competing obligations. There is a need for scalable remote interventions that can reach and serve a larger population. Methods: We conducted a mixed methods pilot study to assess the feasibility, acceptability and impact of CaRE@Home: an 8-week online multidimensional cancer rehabilitation and exercise program. Feasibility and acceptability data were captured by attendance and adherence metrics and through qualitative interviews. Preliminary estimates of the effects of CaRE@Home on patient-reported and physically measured outcomes were calculated. Results: A total of n = 35 participated in the study. Recruitment (64%), retention (83%), and adherence (80%) rates, along with qualitative findings, support the feasibility of the CaRE@Home intervention. Acceptability was also high, and participants provided useful feedback for program improvements. Disability (WHODAS 2.0) scores significantly decreased from baseline (T1) to immediately post-intervention (T2) and three months post-intervention (T3) (p = 0.03 and p = 0.008). Physical activity (GSLTPAQ) levels significantly increased for both Total LSI (p = 0.007 and p = 0.0002) and moderate to strenuous LSI (p = 0.003 and p = 0.002) from baseline to T2 and T3. Work productivity (iPCQ) increased from T1 to T3 (p = 0.026). There was a significant increase in six minute walk distance from baseline to T2 and T3 (p < 0.001 and p = 0.010) and in grip strength from baseline to T2 and T3 (p = 0.003 and p < 0.001). Conclusions: Results indicate that the CaRE@Home program is a feasible and acceptable cancer rehabilitation program that may help cancer survivors regain functional ability and decrease disability. In order to confirm these findings, a controlled trial is required.
