Abstract

ost patients with rectal cancer are treated with curative-intent surgery; adjuvant chemotherapy and radiation are often used as well. A recent survey of members of the American Society of Colon and Rectal Surgeons (ASCRS) revealed considerable variation in surveillance intensity after primary treatment. We evaluated whether geographic factors may be responsible for the observed variation. Vignettes of hypothetical patients and a questionnaire based on the vignettes were mailed to the 1782 members of ASCRS. Repeated-measures analysis of variance was used to compare practice patterns, as revealed by the responses, according to US Census Regions and Divisions, Metropolitan Statistical Areas (MSA), and state-specific managed care organization (MCO) penetration rates. There was significant variation in surveillance intensity according to the US Census Region and Division in which the surgeon practiced. Non-US respondents employed CT of the abdomen and pelvis, chest radiography, and colonoscopy significantly more often than US respondents. MSA was not a significant source of variation. Surveillance patterns varied significantly by MCO penetration rate for office visits and CT of the abdomen and pelvis but not for other modalities. The US Census Region and Division in which the surgeon practices have a significant effect on surveillance intensity following completion of primary curative-intent therapy for rectal cancer patients. The MSA in which the surgeon practices does not affect surveillance intensity significantly and MCO penetration rate affects follow-up intensity minimally. All significant differences are clinically rather modest, however. These data should be useful in the design of controlled trials on this topic.
