Despite controversies, postoperative surveillance of colorectal cancer is generally recommended. This registry-based study was designed to assess the adherence of surveillance practices to French guidelines and identify three-year surveillance patterns and their demographic and clinical determinants.
METHODS
All patients (N = 409) diagnosed with first colorectal cancer in 1998 and alive without recurrence at least six months after curative surgery were identified from a population-based registry. Medical charts from multiple sources were reviewed to collect exhaustive information on follow-up procedures used during a three-year period. Multiple correspondence and cluster analyses were used to identify surveillance patterns.
RESULTS
The proportion of patients with a lower surveillance than that recommended was 35 percent for clinical examination, 65 percent for abdominal ultrasound, 52 percent for chest x-ray, and 20 percent for colonoscopy. Cluster analysis identified three patterns called minimal, moderate, and intensive surveillance patterns, which included 47, 24, and 29 percent of the patients respectively. The main independent predictors of both moderate and intensive surveillance patterns vs. minimal pattern were advanced tumor stage, chemotherapy, and radiation therapy. Younger age also was strongly associated with the intensive surveillance pattern, and the presence of symptoms with the moderate surveillance pattern.
CONCLUSIONS
Adherence of surveillance practices to French guidelines seems relatively poor. Surveillance patterns are mainly explained by patient age, tumor stage, and treatment modalities.
