This paper reports fourteen cases of advanced and recurrent gynecologic cancers treated with prolonged arterial perfusion chemotherapy by catheterization of both internal iliac arteries through femoral arteriopuncture under X-ray. The immediate effective rate was 78.5%, follow-up rate 100%. By this technique anticancer drugs can be selectively injected into vessels supplying the tumors. The drug is concentrated within the tumor resulting in longterm better local effects, and fewer general side reactions, and a much higher dose than that which could be given conventionally. This technique is considered as a new route of treatment in gynecologic tumors.
