[Concurrent chemoradiation therapy for advanced cervical cancer].

ABSTRACT

In 2003, we began a clinical application of concurrent chemoradiation therapy (CCR) in patients with cervical cancer in our hospital. We analyzed 14 cases of advanced cervical cancer in stages IIa through IIIb by FIGO classification. Tumor size of the uterine cervix ranged from 1.5 cm to 8.0 cm in diameter. Patients received radiation therapy (50 Gy of external beam radiotherapy for pelvis and 20 Gy of high-dose rate intracavitary brachytherapy) combined with chemotherapy. Cisplatin was administered intravenously every 3 weeks at a dose of 70 mg/m(2) during the radiation therapy. In two cases, CCR was stopped because of the side effects. One case developed acute renal failure and another suffered intolerable exhaustion. As for the antitumor effects of CCR, the response rate was 75% (CR 58.3%,PR 16.7%). At the end of the CCR, 10 of 12 patients (83.3%) were negative for viable cells by cytology or biopsy of the uterine cervix. The grade 3 adverse effects were leukopenia, diarrhea and anemia. There was no statistical difference in the overall survival between CCR and radiation therapy alone. The CCR response rate in patients with paraaortic lymph node swelling (suspected metastasis) was low, and they had a poor prognosis. Further examinations for the long-term survival benefit of CCR are necessary.
