Pathologic Factors Affecting Colorectal Cancer Survival in a Jamaican Population-the UHWI Experience.

Colorectal carcinoma (CRC) is the third most common cancer and a leading cause of cancer-related deaths in Jamaica. Globally, CRC mortality rates have been decreasing in developed countries; however, CRC mortality rates are trending upwards in low-income or developing countries. Our objectives are to estimate the overall 5-year survival and to determine the pathologic factors associated with overall survival of colorectal adenocarcinoma after surgery at the University Hospital of the West Indies (UHWI).Retrospective, observational (cross-sectional) study on CRC patients. We summarized and analyzed demographic, clinical data, histopathological data, and survival rates. Single predictor Cox regression models were used to establish associations between survival and specified clinicopathological characteristics.A total of 217 patients who underwent operative resection of colorectal adenocarcinoma from January 2004 to December 2013. Median survival time post-therapeutic intervention was 48 months. Late stage at diagnosis, positive circumferential resection margins, neural and vascular invasion, as well as three or more nodal metastases were all associated with statistically significant worsened outcome.Despite surgical quality meeting USA standards, CRC survival rates in Jamaica are 13% lower than survival of CRC in non-Hispanic Blacks in the USA. The survival trends found by our study support the application of international indices for CRC prognostication to Jamaican patients.
