[Geographic variability in the appropriateness of surgical treatment of breast carcinoma].

To assess appropriateness of surgical care delivered to breast cancer patients in Italy and quantify the use of unnecessary radical procedures, a retrospective charts review of patients treated in 1988-1989 was conducted. Information about hospital characteristics was collected directly from administrative departments as a part of a national survey. A series of 1724 consecutive patients (median age 61 years; range 17-89) treated in 63 hospitals selected from within 8 regions, with newly diagnosed operable breast carcinoma was evaluated. Overall, 541 (38%) patients had inappropriate surgery with more than two thirds of it being accounted for by the use of unnecessary mutilating Halsted mastectomy. About one-fourth of patients with stage I-II disease undergone mastectomy according Halsted technique and conservative surgery in patients with small tumors (i.e. tumor size < = 2 cm) was under utilized. Substantial geographic variations emerged in the overall rates of inappropriateness (range 12-48%) which were not substantially affected by allowance for imbalances in patient- and hospital-related variables. Despite the important contribution given by Italian clinical researchers to the demonstration that less radical surgery can be as good as more radical procedures, still a substantial proportion of breast cancer patients are treated too aggressively. Besides pointing to the urgent need of interventions aimed at promoting more appropriate surgical care these results suggest that efforts to increase patients' participation into treatment decision and awareness about alternative treatment options are warranted.
