Abstract
Background: Survival is reduced in African–Americans (AAs) diagnosed with colorectal cancer (CRC), especially in those <50 years old, when compared with Caucasian Americans (CAs). Yet, the role of clinicopathologic features of CRCs on racial differences in survival needs further study. Materials & methods: Over 1000 individuals (CA 709, AA 320) diagnosed with CRC were studied for survival via the Cox proportional hazards regression analysis based on race and risk of death in two age groups (<50 or 50+). Results: Risk of death for younger AAs (<50) was elevated compared with younger CAs (hazard ratio [HR] 1.98 [1.26–3.09]). Yet no racial differences in survival was observed in older cohort (50+ years), HR 1.07 (0.88–1.31); p for interaction = 0.01. In younger AAs versus CAs only, colonic location attenuated the risk of death. Conclusion: The tumor location and histology influence the poorer survival observed in younger AAs suggesting these may also influence treatment responses.
期刊介绍：
Colorectal cancer is a major cause of morbidity and mortality, particularly in the developed world. Risk factors for colorectal cancer are on the rise in many countries; populations are aging, and obesity and diabetes are increasing. National screening programs are helping to detect cancer while it is still curable; however, colorectal cancer remains the third leading cause of cancer deaths in the USA and options are still limited for those with more advanced disease. Consequently, colorectal cancer is a major research priority for government, pharmaceutical companies and non-profit organizations. Research into diagnosis and optimum treatment of the disease is progressing rapidly, with new advances reported every day. Colorectal Cancer presents reviews, analysis and commentary. on all aspects of colorectal cancer.
