Until a few years ago, for patients with ovarian cancer at III stage FIGO, the radiotherapy with moving strip technique followed surgery. The introduction of new chemotherapy agents, Cisplatinum and Adriamycin, has recently changed the course of therapy in the attempt to improve the ovarian cancer prognosis at advanced stages. The authors present a "moving strip" technique which has been revisited to satisfy new request of the therapeutic radio-chemotherapy and surgery method, and moreover they study the real differences between some moving strip technique already published and they describe their characteristics and radiobiologic limits.
