RESUMO
Objective To evaluate the effect of preoperative chemotherapy on bulky cervical cancer by internal iliac arterial infusion. Methods One hundred and eighty-six patients with bulky cervical cancer were randomly divided into two groups: chemotherapy + radiotherapy group (C+R group, n=105) and radiotherapy group (R group, n=81). Patients in C + R group underwent internal iliac arterial infusion chemotherapy by using Seldinger technique internal iliac arterial or epigastric arterial catheterization. Combined regimens were prescribed including cisplatin as the major drug. Meanwhile ~192 Ir high-dose-rate intracavitary radiotherapy was performed,with A point dose at ~12-24 Gy/2-4 times (C + R group). Patients in R group were only given radiotherapy. Both groups of patients received radical hysterectomy two weeks after radiotherapy. Results The tumor regression rate of C+R group was 97.1%, significantly higher than 79.0% in R group(P0.05). Postoperative pathologic examinations showed the percentage of cervical tumor residue, parauterine invasion,pelvic lymph node metastasis in C+R group was lower than those of R group(P
