Abstract
To clarify the effect of neoadjuvant intraarterial infusion chemotherapy on the cure rate in advanced cervical cancer with bulky tumor, a total of 50 patients were examined prospectively. The clinical stage according to the International Federation of Gynecology and Obstetrics (FIGO) classification included 23 IIb, 6 IIIa, and 21 IIIb. These patients were randomly divided into the neoadjuvant intraarterial infusion chemotherapy group and the control group. There were no significant differences in mean age, FIGO clinical stage, and tumor histology between groups. Twenty-five patients in the former group were given 25 mg/m2 of cisplatin and 15 mg/m2 of bleomycin via each internal iliac artery. If the results of the evaluation indicated that surgery was feasible, radical surgery was performed. The patients whose tumors were inoperable received radiation therapy consisting of external irradiation and intracavitary irradiation. Twenty-five patients in the control group also underwent the same radiation therapy. The overall response rate was 80.0%. Eighteen of 20 responders underwent surgery. The 3-year survival rate was 85.7% for operated patients, 42.9% for patients receiving neoadjuvant intraarterial infusion chemotherapy followed by irradiation, and 49.5% for the control group. In the present study, neoadjuvant intraarterial infusion chemotherapy did not improve the prognosis of patients with advanced cervical cancer compared to radiation therapy alone, and only responders who underwent surgery obtained an advantage in survival.
