    Background: Many patients with colon cancer cannot fully adhere to postoperative chemotherapy due to dose-limiting toxicities, resulting in lower relative dose intensity (RDI) and potentially compromising overall survival. This study examined whether home-based resistance training (RT) during adjuvant chemotherapy improves RDI and patient-reported toxicities versus usual care (UC) in colon cancer patients. Methods: Multicenter, randomized control trial (RCT) conducted at community and academic practices. Enrollment of patients receiving postoperative chemotherapy for colon cancer occurred between February 23, 2018, and September 29, 2021; final follow-up was March 21, 2022. Participants were randomized to RT (n = 90) or UC (n = 91) for the duration of chemotherapy. Participants in the RT group engaged in twice weekly home-based progressive RT. At the end of the study, UC was given an online exercise program. Results: Among 181 randomized patients (mean age, 55.2 [SD, 12.8] years, 95 [52.5%] were men), there were no differences in the mean RDI among those in RT (79% [SD, 19%]) and those in UC (82% [SD, 19%]); (mean difference -0.04 [95% confidence interval (CI), -0.09 to 0.02]). Assignment to RT did not significantly reduce the number of moderate/severe symptoms per week across follow-up (relative rate: 0.94 [95% CI, 0.72-1.22]). Additionally, time since randomization did not significantly modify the effect of RT on the overall number of symptoms (p = .06). Conclusions: Among patients with colon cancer, these results do not support home-based RT as an adjunct to chemotherapy specifically to improve planned treatment intensity.
