Abstract
e15050 Background: Management of metastatic colorectal cancer (CRC) has revolutionised over the past 2 decades and a number of drugs are part of active disease management including biologicals. Published large database on metastatic CRC outcome has been lacking from India. Methods: A retrospective data analysis of metastatic CRC from prospectively based database was performed from the year, 2001-2015. All patients who have received at least 1 cycle of chemotherapy were enrolled. Kaplan Meier analysis was done for overall survival (OS). Cox-regression model was done to determine prognostic factors of OS. Results: A total of 288 patients including upfront metastatic (n = 197, 68%) and relapsed (n = 91, 32%) with male to female ratio of 1.4:1 and median age of 46 years were studied. CEA was high in 78% with median level of 20 ng/ml. Most common site of primary tumor location was rectum (47%). Proportions of left side, right side and transverse colon was 75%, 20% and 4.2%. Mucinous and signet histologies were seen in 24% and 9.2% of patients. Most common sites of metastases being liver (43%), peritoneum (31%) and lung (18%). Oxaliplatin based therapy was used 71% of patients as 1st line. Median chemotherapy cycles for both 1st and 2nd line regimen was 6. Biologicals were part of 1st line regimen in only 12.5% of patients. Median OS of our cohort was 18.5 months. Predictors of poor OS were ECOG PS > 1 (HR 2, CI: 1.3-3.3, p value = 0.003), high CEA ( > 5ng/ml, HR 2.5, CI: 1.3-4.6, p value = 0.004), low albumin (< 3.5 g/dl, HR 1.7, CI: 1.03-2.9, p value = 0.045), < 2 lines of chemotherapy received (HR 2, CI: 1.3-3.3, p value = 0.001). Conclusions: Outcomes of metastatic CRC in our cohort with use of doublet chemotherapy (small proportion with biologicals) is comparable to published literature worldwide. We have higher proportion of younger population, rectum cancer, signet and mucinous histology and higher incidence of peritoneal involvement.
