Background: Stage IV/metastatic colorectal cancer (mCRC) is a disease with a poor prognosis. In this condition, chemotherapy remains the main therapeutic modality to control disease progression and prolong survival. Patient survival is influenced by various factors involved in the course of the disease and response to therapy.
Objective: To evaluate the two-year survival rate of patients with mCRC receiving chemotherapy and identify factors associated with their survival outcomes.
Methods: This study employed a retrospective cohort design involving patients with mCRC who received chemotherapy at Dr. Sardjito General Hospital, Yogyakarta, between July 2021 and July 2023. Survival was analyzed using the Kaplan–Meier method, while prognostic factors were examined using the log-rank test and Cox multivariate regression analysis.
Results: A total of 105 patients met the study criteria. The median survival was 18 months, with survival rates of 87.2% at 6 months, 66.9% at 12 months, 47.0% at 18 months, and 38.3% at 24 months. The survival range was 1–69 months. Multivariate analysis showed that performance status (ECOG) was the only factor significantly associated with survival (HR 2.901; p = 0.007), while age, sex, body mass index, marital status, tumor location, metastatic sites, morphological subtype, CEA levels, and chemotherapy regimens showed no significant association.
Conclusion: The median survival of patients with mCRC receiving chemotherapy was 18 months, with ECOG performance status serving as the only independent predictor significantly influencing survival.
