RESUMO
OBJECTIVE: 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). METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

BACKGROUND AND PURPOSE: The purpose of this study was to determine the prevalence of carotid stenosis among patients presenting to the University Hospital of West Indies (UHWI) Accident and Emergency Department (A&E) with an ischemic stroke or transient ischemic attack (TIA). METHODS: Beginning in August 2006, all patients presenting to the UHWI A&E with an acute stroke or TIA were screened for enrollment. Patients were excluded if they had a hemorrhagic stroke or if informed consent could not be obtained. Demographic and clinical information were collected by chart review and interviewer-administered questionnaires. All participants had noncontrast head computed tomography (CT) and bilateral carotid duplex ultrasounds. RESULTS: 133 patients were enrolled in the study. 90% presented with a stroke and 10% with a TIA. Mean age was 64 years, 52% were male, 96% self-identified as black. 78% had diabetes mellitus or hypertension or both, 27% were current or past smokers. 65.1% had a normal carotid ultrasound, 28.5% had <50% stenosis, 1.6% had 50% to 69% stenosis, 0.8% had >or=70% stenosis to near occlusion, 1.6% had near occlusion and 1.6% total occlusion. CONCLUSIONS: The prevalence of moderate or high-grade carotid stenosis in this high-risk black Caribbean population presenting with an ischemic stroke or a TIA is 5.6%. This is lower than that described in other populations. Further studies are needed to determine the cost-effectiveness of routine screening for carotid stenosis in this population.
