TREATMENT OF PATIENTS WITH SUBOPTIMAL ('BULKY') STAGE IB CARCINOMA OF THE CERVIX: A RANDOMIZED COMPARISON OF RADICAL HYSTERECTOMY AND PELVIC AND PARA-AORTIC LYMPHADENECTOMY WITH OR WITHOUT NEOADJUVANT VINCRISTINE AND CISPLATIN CHEMOTHERAPY, PHASE III

OBJECTIVES: I. Compare disease free survival, overall survival, and local control in patients with bulky stage IB carcinoma of the cervix treated with radical hysterectomy and pelvic and para-aortic lymphadenectomy with or without neoadjuvant vincristine and cisplatin. II. Compare adverse effects of radical hysterectomy and pelvic and para-aortic lymphadenectomy with or without neoadjuvant vincristine and cisplatin in these patients. OUTLINE: This is a randomized study. Patients are randomized to 1 of 2 treatment arms. Arm I: Surgery. All patients undergo intra-abdominal and retroperitoneal exploratory laparotomy. Patients without metastases also undergo radical hysterectomy with pelvic and para-aortic lymphadenectomy. Beginning 2-4 weeks after surgery, patients with 1 or more positive lymph nodes or positive surgical margins on the radical hysterectomy specimen receive adjunctive radiotherapy 5 days each week for 4-6 weeks. Patients with histologically confirmed metastases do not undergo radical hysterectomy with pelvic and para-aortic lymphadenectomy, but receive radiotherapy 5 days each week for 6-8 weeks beginning 2-4 weeks after the laparotomy. Patients who undergo radiotherapy also receive cisplatin IV over 1 hour on days when radiotherapy is administered for up to 6 doses of cisplatin. Arm II: Patients receive vincristine IV bolus immediately followed by cisplatin IV over 1 hour on days 1, 11, and 21. Courses repeat every 21 days for up to 3 courses in the absence of disease progression or unacceptable toxicity. Beginning approximately 4 weeks after the last doses of neoadjuvant vincristine and cisplatin, patients receive surgery, radiotherapy, and cisplatin as in Arm I. Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter. PROJECTED ACCRUAL: A total of 170-340 patients will be accrued for this study over approximately 4.5 years.
