Summary

This randomized controlled trial is designed to compare the efficacy and safety of two commonly used chemotherapy regimens, FOLFOX-6 and CAPOX, in adults with metastatic colorectal carcinoma who are receiving chemotherapy after surgery at the Department of Oncology, Jinnah Hospital, Lahore. A total of 248 eligible patients aged 20 to 70 years will be enrolled using consecutive sampling and randomly allocated in equal numbers to receive either CAPOX or FOLFOX-6 according to standard dosing schedules. Participants will be followed for 3 months to determine whether meaningful differences exist between the two regimens in clinically important outcomes. The primary comparison will focus on disease progression within the follow-up period. Additional safety and treatment feasibility outcomes will include the need for chemotherapy dose reduction due to toxicity, treatment discontinuation, hepatotoxicity based on liver function abnormalities, diarrhea persisting for more than 3 days, and mortality during follow-up. The study hypothesis is that the outcomes of FOLFOX-6 and CAPOX differ in terms of effectiveness and adverse effects. The findings are expected to inform selection of a regimen that provides better disease control with fewer treatment-limiting side effects in the local clinical setting.
