| Abstract |
The usefulness of neoadjuvant chemotherapy (NAC) regimens has been reported; however, the effect of NAC for advanced stages (especially stage III-IVA) is thought to be insufficient. We conducted a phase I-II study of neoadjuvant chemoradiotherapy consisting of intra-arterial (i.a.) infusion of carboplatin and intracavitary brachytherapy in patients with locally advanced cervical cancer to achieve the new NAC method. Sixteen eligible patients included those with previously untreated stage IIB, III or IVA cancer with bulky tumor. Brachytherapy using iridium-192 was performed with concurrent i.a. chemotherapy with carboplatin (200, 300 and 400 mg/m2). Treatment was repeated every 4 weeks for a total of two cycles. Both hematologic and non-hematologic toxicities were generally mild. Grade 4 hematologic toxicity was observed in 12.5% and there were no grade III or IV non-hematologic toxicities. The optimal dose of carboplatin was determined to be 400 mg/m2. Among 16 patients, six showed complete response (37.5%) and nine showed partial response (56.3%), for an overall response rate of 93.8%. All 15 responding patients underwent radical surgery with a pelvic lymphadenectomy and postoperative radiotherapy. The combination of brachytherapy and i.a. chemotherapy with carboplatin is a promising regimen for NAC in locally advanced cervical cancer.
