title: [Antitumor action of cis-dichlorodiammineplatinum(II) and the effectiveness of a combination with sarcolysine].
abstract: Therapeutic properties of cis-dichlorodiammineplatinum (II) were studied on 12 strains of transplantable tumors and leukemias in mice. The compound is characterized by a wide spectrum of antitumor action. The greatest effect was gained in adenocarcinoma of the lage intestine (strain AKATOL), proventricular cancer (strain PRG) and adenocarcinoma of the mammary gland (strain Ca-755). The terms of survival in mice with leukemia (strain La and L-1210) and ascites hepatoma 22 are increased considerably. In some L-1210 animals the complete cure was noted. Cis-dichlorodiammineplatinum (II) may be effectively combined with sarcolysin. Much greater antitumor effect was obtained on 3 tumor strains (AKATOL, Ca-755 and sarcoma 37) with the combined therapy than with each drug used separately. The histological study of Ca-755 during chemotherapy indicated that immunocompetent cells of the organism play an important role in the mechanism of antitumor action of the platinum complex. This is manifested in the development of intensive lymphohistiocytic reaction around and inside the tumor. A damage to the convoluted tubules of the kidney and intestinal villi is one of the main adverse side-effects of the combination.
