    Abstract:
    BACKGROUND: Doxorubicin and cisplatin are the most commonly used chemotherapeutic agents in the treatment of endometrial cancer, but their clinical efficacy is still controversial. The aim of this study was to retrospectively assess the efficacy and toxicity of combination chemotherapy using cisplatin, cyclophosphamide, and anthracy-clines in patients with stage III/IV adenocarcinoma of the endometrium. METHODS: Forty patients with advanced endometrial cancer received postoperative adjuvant combination chemotherapy, using cisplatin (50 or 70 mg/m2), cyclophosphamide (500 mg/m2), and one of three anthracyclines (10 patients with doxorubicin [50 mg/m2], 18 with epirubicin [50 mg/m2], and 12 with pirarubicin [40 mg/m2]), from 1987 to 1999. All patients underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy, with pelvic lymph node dissection in 36 patients and paraaortic lymph node biopsy in 38 patients. Patients were considered eligible if they had adnexal metastasis, paraaortic lymph node metastasis, positive peritoneal cytology, or distant metastasis. The patients were divided into two groups: patients with no measurable lesion (group 1; n = 27), and those with residual measurable lesion (group 2; n = 13) after surgery. The response rate and progression-free survival rate were evaluated in group 2. RESULTS: In group 1, 7 patients (26%) had recurrence, and all of them died of the disease. No patients in stage IIIa (n = 10), however, had recurrence. In group 2, 6 of the 13 (46%) showed response to chemotherapy (complete response [CR], 31%; partial response [PR], 15%). Toxicity was moderate: 10 patients had grade 4 neutropenia; and dose reductions were mandated in 12 patients. CONCLUSION: In group 1, the survival of patients receiving chemotherapy was considered favorable, but patients with recurrent lesions had poor prognosis. On the other hand, in group 2, the efficacy of the chemotherapy was almost equal to that reported in the literature; however, this regimen did not contribute to an improvement in the survival rate. In conclusion, a new effective regimen of postoperative adjuvant therapy is highly desirable in patients with measurable residual lesions.
