Racial and ethnic differences in lymph node examination after colon cancer resection do not completely explain disparities in mortality.

摘要: BACKGROUND: In 1999, a multidisciplinary panel of experts in colorectal cancer reviewed the relevant medical literature and issued consensus recommendation for 12-lymph node (LN) minimum examination after resection colon cancer. Some authors have shown racial/ethnic differences receipt this evidence-based care. To date, however, none has investigated correlation between disparities LN outcomes treatment. METHODS: This retrospective analysis used California Cancer Registry linked to Office Statewide Health Planning Development discharge data (1996-2006). Chi-square analysis, logistic regression, Cox proportional hazard models predicted an adequate effect inadequate exam on mortality disparities. Patients with stage I II cancers undergoing surgery were included; patients III IV disease excluded. RESULTS: A total 37,911 records analyzed. Adequate staging occurred fewer than half cases. An (<12 LNs) was associated higher rates. Hispanics had lowest odds receiving exam; blacks, not Hispanics, highest risk compared whites. This disparity completely explained by examination. CONCLUSIONS: Inadequate occurs often is increased mortality. There are exam, but only explains small part observed Improving quality alone unlikely correct 2011;. © 2011 American Society.
