CETUXICOL, a phase II trial randomizing standard treatment with or without cetuximab in primary cervical cancer treatment.

e15535 Background: Advanced stage cervical cancer (CC) remains a public health issue despite preventive vaccines and screening. EGFR is over-expressed in 50 to 85% of CC and activated in 20%, suggesting that EGFR blockage may be a promising treatment approach. Methods: A randomized phase 2 trial on 78 stage IB2–III patients from 11 French Cancer Centres evaluated the tolerance and early response to cetuximab, an anti EGFR antibody. 40 patients received cetuximab + standard RT and Cisplatinum based chemotherapy (arm A) and 38 patients received standard treatment (B). Primary endpoint is DFS at 2 years and presently not reached. MRI imaging revealed no difference in median (44 vs 40) tumour sizes between arms; there was no difference in age, menopausal status, PI and smoking habits. Parametrial involvement was clinically diagnosed in 19 and 20 cases respectively. Presence of lumbar or para-aortic lymph nodes was an exclusion criterion. Three patients withdrew consent in the cetuximab arm, one accepted stand...
