BACKGROUND Adequate lymph node evaluation is required for proper staging of colorectal cancer, and the number of lymph nodes examined is associated with survival. According to current guidelines, the recommended minimum number of lymph nodes examined to ensure adequate sampling is 12. We used data from the National Cancer Institute's Surveillance,(More)
CONTEXT Several studies suggest improved survival among patients in whom a higher number of nodes are examined after colectomy for colon cancer. The National Quality Forum and other organizations recently endorsed a 12-node minimum as a measure of hospital quality. OBJECTIVE To assess whether hospitals that examine more lymph nodes after resection for(More)
OBJECTIVE To describe unplanned procedures following colorectal cancer surgery that might be used as intermediate outcome measures, and to determine their association with mortality and length of stay. SUMMARY BACKGROUND Variation in the quality of surgical care, especially for common illnesses like colorectal cancer, has received increasing attention.(More)
OBJECTIVE This study describes racial differences in postoperative mortality following 8 cardiovascular and cancer procedures and assesses possible explanations for these differences. SUMMARY BACKGROUND DATA Although racial disparities in the use of surgical procedures are well established, relationships between race and operative mortality have not been(More)
OBJECTIVES The incidence and mortality from colorectal cancer among whites have decreased, but they have remained unchanged among African Americans. To explain this disparity, we used the multicenter endoscopy database of the Clinical Outcomes Research Initiative to compare the prevalence of proximal polyps and tumors among asymptomatic African Americans(More)
HYPOTHESIS We hypothesized that there are significant racial disparities in delivery of care to rectal cancer patients. We examined differential surgical and radiation treatment for these patients and determined whether blacks were less likely than whites to undergo sphincter-sparing procedures, which are associated with a higher quality of life than(More)
To assess decision-making for cancer treatment among racial/ethnic minority patients, we systematically reviewed and synthesized evidence from studies of "shared decision-making," "cancer," and "minority groups," using PubMed, PsycInfo, CINAHL, and EMBASE. We identified significant themes that we compared across studies, refined, and organized into a(More)
BACKGROUND American Indians/Alaskan Natives (AI/ANs) have the worst 5-year cancer survival of all racial/ethnic groups in the United States. Causes for this disparity are unknown. The authors of this report examined the receipt of cancer treatment among AI/AN patients compared with white patients. METHODS This was a retrospective cohort study of 338,204(More)
BACKGROUND Increased infertility in women has been reported after ileal pouch-anal anastomosis (IPAA) for ulcerative colitis but reported infertility rates vary substantially. AIMS (1) To perform a systematic review and meta-analysis of the relative risk of infertility post-IPAA compared with medical management; (2) to estimate the rate of infertility(More)
PURPOSE To determine the impact of preoperative radiotherapy (RT) on the accuracy of lymph node staging (LNS). Preoperative RT is a well-established component of rectal cancer treatment but its impact on LNS is unknown. METHODS AND MATERIALS The Surveillance, Epidemiology and End Results (SEER) registry, representing 14% of the U.S. population, was used(More)
