To determine whether adjuvant chemoradiation (CRT) with weekly cisplatin improves recurrence-free survival (RFS) compared with radiation (RT) in pathologically proven intermediate risk early-stage cervical cancer following radical hysterectomy and lymphadenectomy. Post-surgical patients with stage I-IIA cervical cancer with pathologically noted intermediate risk factors including combinations of capillary lymphatic space involvement, stromal invasion, and tumor size were randomly assigned in a 1 : 1 ratio to receive either adjuvant CRT or RT (NCT01101451). Patients received conformal RT, or intensity modulated radiation therapy. In the CRT arm, 6 weekly cycles of cisplatin 40 mg/m Of the 340 randomized patients, 316 were eligible and most had Federation of Gynecology and Obstetrics (2009) stage IB Although RFS and OS favored CRT, the addition of cisplatin during RT did not statistically improve RFS or OS in cervical cancer patients with intermediate pathological risk factors following radical hysterectomy and lymphadenectomy. CRT increased grade 3 and 4 AEs with a transient decline in QoL.
