MedicalResearch.com: What are the main findings of the study?

Dr. Murphy: This study evaluated racial disparity in metastatic colorectal cancer. In a large population-based cohort we found of over 11,000 patients we found that black patients were less likely to be seen in consultation by a cancer specialist, and were less likely to receive treatment with chemotherapy, surgery, or radiation. Furthermore, we found that this disparity in treatment accounted for a substantial portion of the race-based differences between black and white patients.
MedicalResearch.com:  Were any of the findings unexpected?

Dr. Murphy: An abundance of research has found disparity in cancer treatment for minority patients, and another body of literature has identified race-based survival differences. The unexpected finding form our study relates to the observation that race-based differences in survival disappeared after accounting for the disparity in treatment.

MedicalResearch.com:  What should clinicians and patients take away from your report?

Dr. Murphy: Multiple factors likely contribute to treatment disparity in minority populations, though the nature of this study makes it difficult to pinpoint a specific barrier. Potential causes of disparity include health-care access barriers, provider bias, patient mistrust, or communication breakdown. An awareness of racial disparity is important, though there is a substantial need for further research and intervention to reduce inequality in cancer.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Dr. Murphy: To effectively reduce cancer disparity further research should focus on identifying specific racial or ethnic barriers to cancer care. Overcoming these barriers will improve access to treatment and survival in metastatic colorectal cancer.
