PURPOSE: Neoadjuvant chemotherapy (NACT) and radical surgery (RS) have emerged as a possible alternative to conventional radiation therapy (RT) in locally advanced cervical carcinoma. In 1990, a phase III trial was undertaken to verify such a hypothesis in terms of survival and treatment-related morbidity.

PATIENTS AND METHODS: Patients with squamous cell, International Federation of Gynecology and Obstetrics stage IB2 to III cervical cancer were eligible for the study. They received cisplatin-based NACT followed by RS (type III to V radical hysterectomy plus systematic pelvic lymphadenectomy) (arm A) or external-beam RT (45 to 50 Gy) followed by brachyradiotherapy (20 to 30 Gy) (arm B).

RESULTS: Of 441 patients randomly assigned to NACT+RS or RT, eligibility was confirmed in 210 and 199 patients, respectively. Treatment was administered according to protocol in 76% of arm A patients and 72% of arm B patients. Adjuvant treatment was delivered in 48 operated patients (29%). There was no evidence for any significant excess of severe morbidity in one of the two arms. The 5-year overall survival (OS) and progression-free survival (PFS) rates were 58.9% and 55.4% for arm A and 44.5% and 41.3% for arm B (P = .007 and P = .02), respectively. Subgroup survival analysis shows OS and PFS rates of 64.7% and 59.7% (stage IB2-IIB, NACT+RS), 46.4% and 46.7% (stage IB2-IIB, RT) (P = .005 andP = .02), 41.6% and 41.9% (stage III, NCAT+RS), 36.7% and 36.4% (stage III, RT) (P = .36 and P = .29), respectively. Treatment had a significant impact on OS and PFS.

CONCLUSION: Although significant only for the stage IB2 to IIB group, a survival benefit seems to be associated with the NACT+RS compared with conventional RT.
