RESUMEN

Cisplatin is the most important drug in the treatment of advanced ovarian cancer. The role of anthracyclines is controversial. We compared a combination of epirubicin plus cisplatin (EP) with a regimen of cyclophosphamide, epirubicin and cisplatin (CEP). Patients with stage Ic-IV ovarian cancer were randomized to receive either epirubicin 100 mg/m2 plus cisplatin 75 mg/m2 q 4 weeks or cyclophosphamide 500 mg/m2 plus epirubicin 75 mg/m2 plus cisplatin 50 mg/m2 q 4 weeks, which we considered the reference treatment based on our previous experience. Patients were initially debulked, followed by six cycles of chemotherapy, or in case primary debulking was insufficient or considered inappropriate, secondary debulking was attempted in selected cases after sufficient chemotherapy-induced regression. Optimal debulking was defined as residual lesions < or = 2 cm. A total of 210 patients (191 eligible) were randomized. Results did not show significant differences in all major endpoints (pathologically documented complete response and survival). The median survival for all patients was 34 months, for patients with stage III 26 months, for patients with stage IV 20 months and it has not been reached for patients with stage Ic-II. As no significant differences between an equitoxic regimen of EP and CEP were detected, it might be more useful to look again at the anthracyclines as part of combination chemotherapy instead of the alkylating agents.

RESUMEN

BACKGROUND: The Comprehensive Cancer Center trial 82-01 is a prospective randomized study to investigate the value of the addition of high-dose medroxyprogesterone acetate (MPA) to chemotherapy in patients with node-positive operable breast cancer. MPA may be of advantage in this setting because of its activity in estrogen receptor ER-positive as well as ER-negative tumors and since it may protect against chemotherapy-induced myelosuppression and thus enable maintenance of the appropriate chemotherapeutic scheduling. PATIENTS AND METHODS: Four hundred eight evaluable patients with node-positive (N+) operable breast cancer (T1-3, N1) were entered in a multicenter randomized trial. Two hundred nine patients were randomized in the MPA- arm and 199 in the MPA+ arm. CAF chemotherapy was given as a short i.v. bolus infusion: cyclophosphamide 500 mg/m2 i.v. day 1, doxorubicin 40 mg/m2 i.v. day 1, and 5-fluorouracil 500 mg/m2 i.v. day 1, q 4 wks x 6. MPA was given intramuscularly (i.m.) 500 mg q d x 28 days, followed by 500 mg i.m. twice weekly during 5 months. RESULTS: The main side effects of MPA were weight gain with a mean of 5.5 kg as opposed to 1.8 kg in the control group (p = 0.01) and vaginal bleeding in 30/199 in the MPA+ group and 0 in the MPA- group. MPA ameliorated vomiting grade III, IV (45% vs. 28%, p < 0.001), nausea grade III, IV (50% vs. 34%, p < 0.001) and leucocyte nadir grade III, IV (20% vs. 11%, p = 0.003). Disease-free survival (DFS) after 5 years was 59% in the MPA+ and 49% in the MPA- group (p = 0.12). Patients > or = 60 years benefitted most from MPA treatment, in particular if freedom from distant metastases was taken as the endpoint (p = 0.02). Overall survival (OS) was not significantly different between the two treatment groups (p = 0.18), but within subgroups analysed there was an advantage for MPA+ in patients > or = 55 years (p = 0.002) and in pT1 patients (p = 0.045). CONCLUSIONS: High-dose MPA ameliorates CAF side effects and reduces the risk of metastatic disease, especially in elderly breast cancer patients.
