[Effect of continuous bleomycin treatment and of oil-suspended bleomycin on experimental tumor growth (author's transl)].

Abstract

Effects of continuous administration of bleomycin solution and of intralesional injection of sesame oil-suspended bleomycin on tumor growth were studied. Experimental animal tumors were 3 rd generation isotransplants of a spontaneous C3H mouse mammary carcinoma. Bleomycin treatments were started when transplanted tumors reached 8 mm in diameter and the measurement of tumor volume was followed. Dose administered was fixed as 100 mg/kg in all the groups. Bleomycin solution was given intralesionally in a single or 4 daily doses, or intraperitoneally by continuous infusion. The latter method inhibited tumor growth most effectively, while the single injection was the last effective. Intralesional injection of oil-suspended exhibited similar effectiveness as the continuous infusion, and it was independent of the number of fractions. These results were interpreted by the several features in the response of mammalian cells to the antibiotic.
