Are there regional differences in the management of colon cancer in France?
The purpose of this study was to assess possible regional disparities in the management of colon cancer in France. In 1995, 1605 patients with a colon cancer in eight areas covered by a population-based cancer registry were studied. Pre-therapeutic work-up, stage at diagnosis and therapeutic modalities were assessed. There were no differences between areas concerning the resection or the stage at diagnosis. The proportion of patients with a colonoscopy alone varied between 42.7 and 70.4% (P<0.001). The use of both colonoscopy and barium enema was even more heterogeneous (extremes from 11.7 to 40.2%, P<0.001). There were significant differences in the performance of abdominal computed tomography and tumour markers. The number of examined lymph nodes was lower than the recommendation in 47.3% of cases with extremes ranging from 36.9 to 60.9%. Adjuvant chemotherapy was performed on average in 49.4% of cases in stage II (in which it is not recommended) with extremes from 18.8 to 72.5% (P<0.001) and in 79.6% of the cases in stage III (in which it is recommended) with extremes from 63.6 to 94.4% (P=0.08). In conclusion, these results should alert practitioners and health care authorities in order to homogenize practices.
