[Hyperthermic treatment with peplomycin and bestatin in superficial bladder cancer]

In order to study the effect of Bestatin on superficial bladder cancer, the drug was used in combination with hyperthermia and Peplomycin therapy. The study was made using the following 2 groups. Group 1; Hyperthermic treatment with Peplomycin was used in 6 cases of bladder cancer. Group 2; Bestatin was given in combination with hyperthermia and Peplomycin in 15 cases of bladder cancer. As a result, complete or partial regression was obtained in 1 and 5 cases in Groups 1 and 2 respectively. Therefore, the combined use of Peplomycin and Bestatin in hyperthermic treatment for superficial bladder cancer appeared to be effective. Degeneration of tumor cells, irregularity of tumor structure, interstitial edema, fibrosis and cell infiltration were observed in the surgical specimens taken from effective cases, although the mechanism of action of Bestatin on tumors was clearly demonstrated upon histological examination.
