Background: Platinum compounds, taxanes and anthracyclines provide the major effective drug classes in the treatment of advanced and recurrent endometrial cancer and carcinosarcoma.
Patients and methods: A total of 52 women with advanced or recurrent endometrial cancer and carcinosarcoma were treated with four cycles of carboplatin area under the curve (AUC) 5 and doxorubicin (50 mg/m2) for four cycles before or after four cycles of carboplatin AUC5 and paclitaxel (175 mg/m2) with each cycle administered at 21-day intervals.
Results: Thirty-seven patients (71.2%) completed all planned treatment. Excluding six patients who did not complete treatment for non-drug-related causes, 80.4% completed all planned treatment. Three hundred and seventy-one treatment cycles were administered and 303 (81.7%) occurred on time. Common Toxicity Criteria grade 3/4 haematological toxic effects, particularly neutropenia and thrombocytopenia, were the predominant cause of treatment delays and dose reductions. A low incidence of grade 3 neurotoxicity and no cardiac toxicity were observed. The overall response rates for patients with evaluable disease were 82.1% and 66.7% for endometrial and carcinosarcoma, respectively. At a median follow-up of 21 months, the median progression-free survival for the endometrial adenocarcinoma and carcinosarcoma cohorts were 15.3 and 12.0 months, respectively.
Conclusion: This regimen is generally well tolerated with encouraging efficacy.
