The patients randomised to the test arm (Arm A), after determining the clinical FIGO stage, shall initially receive an operative staging in the form of a pelvine paraaortal lymphadenectomy (laparoscopic or open). On the basis of the operatively obtained findings, a ("surgically") modified tumour stage shall be determined. This "surgical" tumour stage, which shall take into account the affection of the lymph nodes, the infiltration of the neighbouring organs and the intraperitoneal spread, shall serve as the basis for the execution of primary, combined radio-chemotherapy. The primary end-point is the disease-free survival of both groups, the secondary endpoints are overall survival, the local control of both groups, as well as the determination of toxicity and the quality of life.
