    Abstract:
    A prospective, single arm, phase-II trial was performed to assess the efficacy and local toxicity of the combination of low doses of platin and pelvic radiotherapy in patients with locally advanced carcinoma of the cervix. January, 1993, through August, 1994, twenty-three previously untreated patients with squamous carcinoma (stages IIB-IIIB UICC) entered the study. All patients were examined by a gynecologist and by a radiation oncologist and then submitted to conventional pretreatment staging procedures. Nine patients were classified as stage IIB and 14 patients as stage IIIB. Radiotherapy consisted of 60 Gy external beam irradiation (46 Gy to pelvis + 14 Gy boost to cervix uteri and parametria) plus one low dose rate intracavitary treatment to a dose of 8 Gy to point A. Cisplatin (3 mg/m2/day) or carboplatin (12 mg/m2/day) was also given for 6 weeks starting on radiotherapy day 1. The treatment was well tolerated and no patient required radiotherapy discontinuation. With a median follow-up time of 20 months, complete response was seen in 74% (17/23) of the patients. One of the 17 patients who achieved a complete remission, during follow-up, relapsed in the pelvis and one developed lung metastases. Total failure rate in the pelvis was 30.5% (7/23). Distant metastases were observed in 17.5% (4/23) of the patients. Actuarial overall and disease-free survival rates at 33 months were 69.1% and 65.2%, respectively. Late gastrointestinal toxicity (grade 3) occurred in 8.6% (2/23) of patients, with one patient developing a rectal ulcer-which was submitted to colostomy- and one patient a vaginal necrosis. The combination of platin and radiotherapy appears to be an effective regimen for the patients with locally advanced carcinoma of the cervix and caused a relatively low rate of late gastrointestinal complications.
