This study aims to evaluate the feasibility, toxicity and efficacy of concurrent chemotherapy with platinum compounds and brachytherapy, for locally advanced carcinoma of the cervix (Stages IIA/B, IIIA). The hypothesis was that synchronous chemo-brachytherapy may be sufficient to cause down-staging of the tumour, to render it operable, and hopefully improve the prognosis. 36 women with locally advanced cervical cancer were treated with concomitant brachytherapy and chemotherapy before surgery and/or definitive external radiotherapy. All patients received two caesium-137 Selectron MDR applications, 1 week apart. The dose calculated to point A for each implant was 20-25 Gy. Chemotherapy consisting of continuous cisplatin infusion (50 mg m2) and of carboplatin (300 mg m-2) was given simultaneously with intracavitary irradiation during the first and second application, respectively. The combined therapy was followed when feasible by radical hysterectomy, pelvic lymphadenectomy and pelvic radiotherapy. Patients deemed ineligible for surgery because of poor response were given full dose external radiotherapy. 31/36 patients were treated by Wertheim hysterectomy of whom 10 had negative lymph nodes and resection margins. Definitive external radiotherapy was given in the remaining five patients. Overall, 83% were disease free at 2.8 years mean follow-up. The most frequent acute side-effects of chemobrachytherapy were nausea and vomiting. No renal toxicity was observed. Thrombocytopenia was seen in five patients and was responsible for delayed surgery in four patients. Concerning late effects, two patients developed grade 2 intestinal sequelae, two mild frequency and two vaginal stenosis. One rectovaginal and one vesicovaginal fistula developed in two patients; and a third patient had a fistula associated with tumour recurrence. Concurrent brachytherapy and chemotherapy with platinum compounds is well tolerated and effective in reducing tumour bulk before definitive local treatment (surgery or external radiotherapy), in patients with locally advanced carcinoma of the uterine cervix.
