Abstract
OBJECTIVE: We evaluated the feasibility of combination chemotherapy with paclitaxel, doxorubicin and cisplatin without prophylactic granulocyte colony-stimulating factor injection for intermediate-to-high-risk or recurrent endometrial cancer. METHODS: Women with histologically confirmed FIGO Stages I-II with >1/2 myometrial invasion, Stage III/IV or recurrent endometrial cancer were enrolled. Patients received intravenous doxorubicin (45 mg/m(2)), followed by cisplatin (50 mg/m(2)) on Day 1 and intravenous paclitaxel (160 mg/m(2)) on Day 2. Granisetron (75 µg) was administered depending on neutrophil counts on Days 3 and 8. Treatment was repeated every 21 days for six cycles or until disease progression or unacceptable toxicity. The primary endpoint was the completion rate of the scheduled chemotherapy; secondary endpoints were Grade 3/4 toxicity and response rate in patients with measurable lesions. RESULTS: From September 2010 to December 2012, 35 women, including 7 with FIGO Stage I, 4 with Stage II, 13 with Stage III, 10 with Stage IV and 1 with recurrent endometrial cancer, were enrolled. There were 26 endometrial carcinomas (Grade 1, 16; Grade 2, 6; Grade 3, 4), 4 carcinosarcomas, 2 serous adenocarcinomas, 1 neuroendocrine carcinoma, 1 poorly differentiated carcinoma and 1 mixed carcinoma. Twenty-five patients (71%) completed six chemotherapy cycles. Grade 3/4 hematological toxicities included neutrocytopenia (97%), thrombocytopenia (6%) and anemia (34%). Three patients (9%) experienced neutropenic fever. Grade 3/4 non-hematological toxicities were observed in 13 patients. In 15 patients with evaluable lesions, the response rate was 80%. CONCLUSIONS: Combination chemotherapy with paclitaxel, doxorubicin and cisplatin without prophylactic granulocyte colony-stimulating factor injection is feasible.
