OUTLINE: Patients are stratified into two groups. Group 1 consists of patients with untreated endometrial and tubal cancers and Group 2 consists of patients with sarcomas and carcinosarcomas (mixed mesodermal tumors) of gynecologic origin subdivided into no or prior therapy. Patients receive doxorubicin HCl liposome intravenously on day 1 of each treatment course. Paclitaxel is administered intravenously weekly on days 1, 8, and 15 of each course. Courses are repeated every 21 days. Treatment continues in the absence of unacceptable toxic effects or disease progression. Patients are followed every 3 months for 2 years, then every 6 months for 3 years, then annually thereafter.
