    Abstract:
    OBJECTIVE: To determine the effectiveness of chemotherapy alone as postoperative adjuvant therapy for intermediate- and high-risk cervical cancer. METHODS: The study group comprised of 65 consecutive patients with stage IB or IIA squamous cell or adenosquamous cervical cancer who were initially treated with radical hysterectomy and pelvic lymphadenectomy between 1993 and 2002. Tumors were of intermediate-risk (stromal invasion > 50%, n = 30) or high-risk (positive surgical margin, parametrial invasion, and/or lymph node involvement, n = 35). In all cases, chemotherapy was administered adjuvantly: three courses of bleomycin, vincristine, mitomycin, and cisplatin for intermediate-risk cases and five courses for high-risk cases. Disease-free survival and complications of the combined therapy were investigated. RESULTS: Estimated 5-year disease-free survival was 93.3% for the 30 patients with intermediate-risk tumors (100% for those with squamous cell carcinoma and 71.4% for those with adenosquamous carcinoma) and 85.7% for the 35 patients with high-risk tumors (89.3% for those with squamous cell carcinoma and 71.4% for those with adenosquamous carcinoma). The incidence of locoregional recurrence was 3.3% in the intermediate-risk group and 8.6% in the high-risk group. Side effects of chemotherapy and complications of the combined therapy were within acceptable limits. No patient had severe bleomycin-related pulmonary toxicity. Only 1.5% of patients developed small bowel obstruction, which was cured by conservative therapy. CONCLUSIONS: The treatment results suggest the potential role of adjuvant chemotherapy alone for patients with cervical cancer.
