Abstract
Background Prognosis of metastatic colorectal cancer (mCRC) is poor and goal of treatment is mainly palliative unless there is limited metastatic disease which is surgically resectable. Here, we report a case series of long-term survivors treated predominantly with chemotherapy.
Methods This is a single-center retrospective analysis of patients of mCRC. Records of metastatic colorectal cancer patients registered at Institute Rotary Cancer Hospital, All India Institute of Medical Sciences, New Delhi, between the year 2005 and 2015 were retrieved and reviewed. Inclusion criteria were patients who survived 5 years or more, treated mainly by chemotherapy, with either initial presentation as metastatic disease or those who progressed after initial surgery with or without adjuvant therapy. The details about the patient characteristics, treatment, and outcome were collected. The data were censored on September 30, 2020.
Results Records of 370 mCRC patients were reviewed. Thirty-one patients with all the available details fulfilled the criteria for inclusion in the study. Median age was 53 years (range, 22–74 years). Sixteen were women (51.6%). Twenty-four (77%) were newly diagnosed cases with initial presentation as metastatic disease. Commonest site of primary was on the left (21, 67.6%) followed by right side and transverse colon in 5 patients each. Liver was the most common site of metastasis (n = 18, 58.06%). In metastatic setting, the most common chemotherapy regimen used in the first line was CAPOX (n = 11, 35.48%). Only three patients could undergo metastatectomy. Monoclonal antibodies could be used only in 14 patients. Median overall survival (OS) of this cohort is 81.6 months (95% confidence interval [CI], 69.73–117.9).
Conclusion A small but significant proportion of mCRC patients may achieve and maintain durable responses and long term survival with use of combination of chemotherapy with or without biologics.
