[Results of neoadjuvant chemotherapy using tri-weekly CDDP/CPT-11 for locally advanced cervical cancer].

ABSTRACT

OBJECTIVE: We assessed the antitumor response and safety of neoadjuvant chemotherapy (NAC) using cisplatin (CDDP) and irinotecan(CPT-11)given every three weeks for locally advanced cervical cancer with a bulky mass. SUBJECTS AND METHODS: Nineteen patients with cervical squamous cell cancer in FIGO stage of Ib2 to IIb were enrolled in this study. The FIGO stages were Ib2 in 5 patients, IIa in 2 patients, and IIb in 12 patients. One course of the chemotherapy regimen consisted of intravenous administrations of CDDP at a dose of 70 mg/m 2(day 1)and CPT-11 at 70 mg/m 2 (days 1 and 8) for 21 days, and two courses were administered. This chemotherapy was assessed for antitumor response, adverse events, complete surgical removal rate, progression-free survival time, and overall survival time. RECIST and NCI-CTCAE were used to determine antitumor response and adverse events, respectively. RESULTS: The results of assessment of the antitumor response showed CR in 3 patients(15. 8%), PR in 14(73. 7%), SD in 1 (5. 3%), and PD in 1(5. 3%). Neutropenia of grade 3 or higher occurred in 13 patients(68. 4%). Anemia occurred in 2 patients(10. 5%), and thrombocytopenia in 1 patient(5. 3%). Nausea and vomiting were observed in 2 patients(10. 5%). All patients underwent a chemotherapy regimen consisting of two courses, and the rate of complete surgical removal was 94. 7%. The median observation period was 27 months; the progression-free survival time was 18 months, and survival time was 27 months. CONCLUSION: Adverse drug reactions to NAC with the CDDP/CPT-11 combination administered every three weeks were controllable. The antitumor response rate for this chemotherapy was high. These assessment results indicate that NAC with a CDDP/CPT-11 combination was useful for local advanced cervical cancer.
