Abstract
Abstract INTRODUCTION: The management of cancer patients changed in the recent years with increased in the number of oral antineoplastic agents (OANA) prescriptions. Recent guidelines encouraged improvement of information and patient education, and the coordination between health care professionals to secure and optimize the management of these drugs. To cope with current recommendations, a multidisciplinary consultation (MDC) for initiation of OANA was initiated at François Baclesse comprehensive cancer center in Caen, France. OBJECTIVE: The aim of this study was to evaluate the benefit of the MDC before the initiation OANA in patients with metastatic breast cancer. MDC consisted of a medical oncologist, hospital pharmacist, and oncology nurse consultations. Primary endpoint was the rate of hospitalizations. Secondary endpoints were treatment discontinuation and of adverse events rate. MATERIALS AND METHODS: We conducted a retrospective single center study comparing patients receiving MDC to the population with a single medical visit. RESULTS: A total of 482 patients were included in this study between January 2017 and December 2019 (329 patients had only a consultation with a medical oncologist before initiation of OANA and 153 had the MDC). A statistically significant decrease in the rate of hospitalizations for toxicity was found in the group of patients with MDC 3.9% (n=6) vs 18.5% (n = 61) in the group without MDC (p < 0.001). A significant decrease in treatment interruption rate for toxicity was found in the group of patients with MDC 11% (n = 16) vs 26% (n=86) (p < 0.001). Adverse events rate was not statistically significant between the two groups CONCLUSION: A statistically significant decrease in hospitalizations and rate of treatment interruption for toxicity was observed after initiation of MDC in patients with a metastatic breast cancer treated with an OANA. This process should be generalized for a better security in the management of the OANA.
