[A phase II study with mitoxantrone-vinorelbine association in the treatment of advanced breast cancer in elderly women].
To assess efficacy and toxicity of less toxic analogs for advanced breast cancer in elderly women, we performed a phase II study using the combination mitoxantrone (MTZ)-vinorelbine (VNR). From January 1991 to May 1993, 25 women older than 70 years received a chemotherapy consisting in 10 mg/m2 of MTZ on day 1, followed by 20 mg/m2 of VNR on day 1 and 8. Cycles were repeated every 21 days for a maximum of ten cycles in the case of an objective response. Sixteen women previously received first line hormonotherapy, eight with only one metastatic site. Twenty-three patients are evaluable for response and toxicity. An objective response was observed in five cases (22%), with a median time to progression of 13 months. More than 75% of the planned dose-intensity, for MTZ and VNR was received by 90 and 57.2% of patients, respectively. Dose-limiting toxicity was myelosuppression but no febrile neutropenia was observed. Extra haematologic toxicities were unfrequent. This combination is well tolerated by elderly women, but best results could be achieved by increasing delivered dose intensity.
