SENTICOL III is large prospective multicenter international randomized study designed to validate the Sentinel Lymph Node (SLN) mapping technique in early cervical cancer. This "validation study" will compare the outcome of patients with negative SLN (experimental arm) vs patients with negative SLN + Pelvic Lymph Node dissection (PLN)(reference arm).

There will be a "quality assurance" program which will be developed in participating centers with detailed requirements in terms of surgeons' qualifications, pathology qualification, SLN ultrastaging, standardization of the procedure, etc. as well as respect of the "safety algorithm".
