New study in Journal of the American College of Surgeons finds racial disparities in screening and treatment for several cancers
CHICAGO (November 12, 2009) – New research published in the November issue of the Journal of the American College of Surgeons shows that African-American patients with colorectal cancer are more likely to be diagnosed with advanced disease and are less likely to undergo surgical procedures compared with Caucasians, suggesting that improvements in screening and rates of operation may reduce differences in colorectal cancer outcomes for African-Americans.
Racial disparities previously have been demonstrated in numerous studies for a number of cancers, typically due to unequal access to care. As a result, the identification and elimination of these disparities has become a national public health priority.
In evaluating an unadjusted analyses, researchers discovered that African-American patients with colorectal cancer were more likely to present with metastatic disease (23.17 percent versus 14.75 percent Caucasians; p(0.05) and less likely to undergo operations (71.25 percent versus 79.05 percent; p(0.05), regardless of socioeconomic factors. This finding was the case even when the analysis was confined to patients with localized, surgically treatable diseases.
The median survival of African-Americans with colorectal cancer (39 months versus 56 months) and esophageal cancer (5 months versus 9 months) in the study was significantly less than that for Caucasians (p ( 0.05). Survival was similarly poor for pancreatic and gastric cancer patients regardless of race.
In conducting a multivariate analysis, the research team found that African-American patients had a higher likelihood of dying from colorectal cancer than Caucasian patients did. However, this difference did not persist when adjustments were made for disease stage and presence or absence of a surgical procedure (hazard ratio = 1.15, 95% CI = 1.06 – 1.24). There was no association between survival and race for patients with esophagus, gastric or pancreatic cancer. Other variables of interest and statistical significance were median household income below $35,000, a dual eligibility insurance status and older age, all of which were negatively associated with colorectal cancer survival. ###
About the American College of Surgeons
The American College of Surgeons is a scientific and educational organization of surgeons that was founded in 1913 to raise the standards of surgical practice and to improve the care of the surgical patient. The College is dedicated to the ethical and competent practice of surgery. Its achievements have significantly influenced the course of scientific surgery in America and have established it as an important advocate for all surgical patients. The College has more than 77,000 members and is the largest organization of surgeons in the world. For more information, visit www.facs.org.
