Enhancement of artificial lung metastases by misonidazole.
The effect of treatment with the hypoxic cell radiosensitizer misonidazole on the formation of artificial lung metastases was examined. Both single treatments with large doses of misonidazole and fractionated treatments with smaller doses of misonidazole were found to increase the number of lung tumors developing after intravenous injection of EMT6 mouse mammary carcinoma cells. The immunologic and physiologic effects of the nitroimidazole were postulated to be responsible for the enhancement of lung tumor formation.
