Purpose: To investigate the longitudinal associations between demographic, clinical and lifestyle factors, and changes in patient-reported outcomes (PROs) in cancer survivors 6–9 years post-diagnosis in Western Australia. Methods: A total of 290 individuals participated in this study. Three-quarters of participants were female, and 55%, 31%, and 14% were survivors of breast cancer, colon cancer, and non-Hodgkin lymphoma (NHL), respectively. PROs (fatigue, depression, and health-related quality of life (HRQOL)) were reported at two time points (2012–13 and 2017). Descriptive statistics were used to assess the overall changes over time and linear mixed models were used to identify factors associated with changes over time, after adjusting for confounders. Results: No significant changes were observed in PROs between time point 1 and follow-up at the population level, yet a notable proportion of participants (23% for fatigue, 10% for depression, and 39% for HRQOL) reported a negative minimal clinically important difference (MCID). Being non-Caucasian and having had NHL were associated with negative changes over time. Being obese and having had radiotherapy were related to improved outcomes. Conclusion: Cancer survivors whose levels of fatigue, depression, and quality of life are compromised during cancer treatment may require intervention even 6–9 years post-treatment. Our results suggest particular attention should be paid to those who are non-Caucasian and who have had NHL. This is crucial for providing appropriate care and to support those who are at increased risk of deteriorating naturally over time. [ABSTRACT FROM AUTHOR]

Background: Understanding of the physical activity and sedentary behavior of cancer survivors is limited by reliance on self-reported data. Here, we report the correlates, and patterns of accumulation, of physical activity (light, and moderate-vigorous; MVPA) and sedentary behavior, in colon cancer survivors, using accelerometer-based assessments.Methods: Colon cancer survivors from Alberta, Canada (n = 92), and Western Australia (n = 93) (overall response rate = 21 %) wore an Actigraph(®) GT3X+ accelerometer for seven consecutive days and completed a questionnaire in 2012-2013. Accelerometer data (60 s epochs) were summarized using Freedson activity cutpoints and were adjusted for wear time. Linear regression analyses, conducted 2014-2015, examined correlates for different intensities of activity.Results: Younger age, being employed, higher family income, and lower BMI were significantly correlated with MVPA, while gender, educational attainment, and BMI were correlated with light-intensity physical activity. Gender, comorbidities, and BMI were correlated with sedentary time. MVPA did not vary by day of the week, whereas the remaining time (as a sedentary/light ratio) showed significant variation, with Saturdays being less sedentary than average [corrected]. When considering time of day, we found that evenings were when the likelihood of both MVPA and sedentary time was highest.Conclusions: The low level of MVPA and high volume of sedentary time demonstrated by these objective data highlight the need for intervention in colon cancer survivors. The correlates and accumulation patterns described by this study may better inform interventions and translational research designed to increase physical activity and reduce sedentary behavior in colon cancer survivors.
