title: [Fundamental studies on arterial infusion chemotherapy for cervical cancer--with reference to the histological finding in infiltrating cancer and localization of the drugs in tissues].
abstract: Preoperative arterial infusion of peplomycin was carried out on 15 cases of Stage I or II cancer of the cervix, and the value of arterial infusion chemotherapy with peplomycin and its efficacy as a preoperative therapy in cervical cancer were evaluated by analysis of (1) histological changes, (2) localization of the drug in tissue, and (3) tissue concentration of the drug in the completely resected tissues, with the following results: The chief histological change was a regression of cancer nests accompanied by degeneration and necrosis of cancer cells. This change was clearer at the head of infiltrating cancers than at their superficial layer or center. Peplomycin was localized with high activity at the disintegrated part of cancer nests, i.e., its activity was closely correlated to the severity of histological change. Time-course changes in its localization suggested the vessel wall----stroma----cancer as the route of its transport. The tissue concentration of peplomycin was maintained high over a long time. Particularly in the portio vaginalis, the time course decline of the concentration was gentle. From the above findings, arterial infusion of peplomycin was considered to be an effective method of chemotherapy for cervical cancer, and worth being tried as a preoperative therapy too.
