ONCO-RET: Supervised Resistance Training During Total Neoadjuvant Therapy for Locally Advanced Rectal Cancer

Starting soon · Not applicable

Conditions studied: Locally Advanced Rectal Cancer

In brief

Colorectal cancer is a major cause of cancer death in Chile. Many people with rectal cancer that has grown into nearby tissues receive chemotherapy and radiation before surgery. These treatments can cause tiredness and loss of muscle, which may make it harder for patients to complete treatment. This study will look at whether a supervised strength-training exercise program is practical and safe during treatment before surgery. Participants will do a personalized strength-training program two times per week. The program will start when cancer treatment begins and will continue until surgery (about 24 weeks). The study will measure how practical the program is by looking at how many people join the study, stay in the study, and attend the exercise sessions, and whether the study team can collect all planned information. The study will also track any problems or side effects related to exercise. The study will also explore whether the exercise program may help maintain muscle, improve strength and physical function, improve quality of life, reduce fatigue, and affect how the tumor responds to treatment. These results will be compared with information from similar patients previously treated at the same hospital.
