One hundred and three patients previously treated with chemotherapy including an anthracycline were entered in a VMMC protocol study: vindesine (Eldisine), mitoxantrone (Novantrone) and mitomycin C (Ametycine). Group A consisted of 41 women who received the protocol published by Belpomme: vindesine (2.5 mg/m2 day 1 and 8) and mitoxantrone (12 mg/m2/day) every 4 weeks, and mitomycin C (8 mg/m2) every 8 weeks. Group B consisted of 62 patients who were treated with a modified protocol: vindesine (2.5 mg/m2) and mitoxantrone (12 mg/m2) every 3 weeks on day 1, and mitomycin C (8 mg/m2) every 6 weeks. Tolerance was acceptable with 79% of patients complaining of weakness. There was a 66% incidence of gastro-intestinal toxicity, a 10.7%-incidence of neurotoxicity (reversible dysethesias), and a 5.8% incidence of cardiotoxicity. There was considerable hematotoxicity of grade 2, 3 and 4: neutropenia 16.6%, thrombocytopenia 7.7%, anemia 21.4%. There was a 19.2% overall objective response rate (CR and PR) (95% confidence interval: 12-30) (CR: 3.2%). The median duration of the response was 39 weeks. There was no significant difference in response rates whether or not the patients (19 cases) were undergoing simultaneous hormonal therapy and no difference according to the protocol used. Similarly, neither menopause nor a previous response to anthracyclines had any effect on the response rate. The 19.2% response in this protocol is similar to other breast cancer salvage chemotherapy protocols for patients who have failed to respond to anthracyclines (< 20%).

Fifty-five consecutive patients with metastatic breast cancer (MBC) (n = 57) were treated with a combination of levofolinic acid (I-FA) 100 mg/m2 plus 5-fluorouracil (5-FU) 340 mg/m2 i.v. on day 1-3, cyclophosphamide (CTX) 600 mg/m2 i.v. on day 1 and mitoxantrone (DHAD) 12 mg/m2 i.v. on day 1. DHAD dose was progressively escalated by 2 mg/m2/cycle up to 18 mg/m2 in the absence of dose-limiting toxicities. Granulocyte colony stimulating factor (G-CSF) was given s.c. in order to prevent neutropenia. DHAD dosage could be increased to 18 mg/m2 in 66 out of 317 cycles of chemotherapy (21%). In most patients the dose-limiting toxicity was represented by myelosuppression. A statistically significant correlation was found between median white blood cell (WBC) or absolute neutrophil count (ANC) nadir and DHAD dose level. Moreover, a statistically significant correlation was observed between the number of chemotherapeutic cycles, nadir ANC and WBC, and the occurrence of anemia and thrombocytopenia of increasing severity. These data suggest the occurrence of progressive cumulative bone marrow toxicity. Although patients who reached different DHAD levels showed differences in mean dose intensity, such differences were not statistically significant. No correlation was found between the increase in dose intensity and type, rate or duration of objective responses. In patients with metastatic breast cancer the overall response rate was 72% (95% CL 57-84%) with a 18% complete response rate. Median duration of response was 12 and 11 months, respectively, for complete and partial responses. Projected median survival of the whole series of patients with MBC was 18 months. These data demonstrate that the combination of 5-FU with I-FA, CTX and DHAD is very active against MBC. G-CSF use allows the increase DHAD dosage up to 18 mg/m2/cycle, but its use may be linked to the occurrence of sometimes severe cumulative hematological toxicity.

In a phase II study, 66 patients with advanced breast cancer (median age 56 years; range, 28 to 75 years) were treated with paclitaxel (Taxol), 175 mg/m2 infused over 3 hours, and carboplatin (Paraplatin), dosed to attain an area under the concentration-time curve (AUC) of 6 mg x min/mL; treatment was repeated every 3 weeks. A total of 38 (58%) patients had received prior adjuvant chemotherapy, 21 with a regimen containing an anthracycline or mitoxantrone (Novantrone). As of May 1997, 295 cycles of paclitaxel-carboplatin have been administered, 248 (84%) at full dose. The relative dose intensity of paclitaxel is 0.9 (range, 0.5 to 1.2). Of the 66 patients, 8 (12%) have achieved a complete response and 27 (41%) a partial response, for a total response rate of 53%. Grade 3 to 4 toxicities have included anemia (5%), leukopenia (25%), thrombocytopenia (5%), nausea/vomiting (7%), myalgias/arthralgias (4%), allergic reaction, neurotoxicity, and infection (2% each). Alopecia has been universal. Median time to progression is 8.9 months; median survival has not yet been reached. We conclude that the combination of paclitaxel and carboplatin has significant activity in advanced breast cancer and can easily be administered on an outpatient basis with manageable toxicity.
