Résumé
Background: EGFR is frequently overexpressed in cervical cancer (CC), suggesting EGFR blockade as a promising treatment approach. Cetuximab, an anti EGFR antibody, used conjointly with radio-chemotherapy, was feasible in first-line treatment of cervix carcinoma limited to the pelvis. Methods: This randomized phaseII trial enrolled 78 FIGO-stage IB2-IIIB CC patients to either Cisplatin based radio-chemotherapy alone (Arm B, n=38) or conjointly with a 6 week course of weekly Cetuximab (Arm A, n=40). Brachytherapy was given to the pelvic mass. Primary endpoint was disease free survival (DFS) at 2 years. EGFR expression and targeted sequencing were performed in 54/78 patients. Findings: Cetuximab over a 6 week period didn't improve DFS at 24 months. At 31 months median follow-up, DFS was not significantly different (p=0*18). Complete response at 4-6 months was strongly predictive for excellent DFS (Log-Rank test; p
