Compliance with radiation treatment guidelines in a provincial setting.

Abstract

Since 1979, consensus guidelines have been produced for radiation treatment practice in British Columbia. These guidelines have been revised, updated and circulated to all radiation oncologists periodically. A comprehensive computer database for all patients receiving radiation treatment in the province was established in 1984. Between 1985 and 1996 inclusive, 7667 prostate cancer patients and 9748 breast cancer patients received primary radical radiation treatment or adjuvant postsurgical treatment. Palliative treatments and the treatment of other disease sites are not included in this review. Compliance of these treatments with the published guidelines is reported. Over 98% of patients completed treatment as planned and, in the last 3 years, more than 90% of patients received a guideline dose to either the prostate or the breast. Compliance was less in the treatment of the regional lymph nodes in breast cancer. Practice in prostate cancer tended to precede the changes in the guidelines. This was not the case for breast cancer.
