[Arterial administration of SMANCS and other antitumor agents dissolved in lipiodol for various malignant solid tumors].

Selective deposition of lipiodol in primary and metastatic liver cancer, lung cancer, gallbladder cancer, pancreatic cancer and renal cancer was elucidated by plain X-ray film and CT. Selective delivery of anticancer agent, SMANCS was also proved by measurement of its biological activities of removed specimen. Because of these selective delivery of anticancer agent and embolization of neovasculature in the tumor, highly effective chemotherapy of unresectable cancer was established. Drug was given via celiac, the hepatic, bronchial or renal artery mostly 1-5 mg in 1-5 ml of lipiodol once every 3-8 weeks. Antitumor effects of this therapy for hepatocellular carcinoma was confirmed based on decrease in AFP levels (92% of the cases), reduction in tumor size (90% of the cases) and histology. In 76 percent of the patients with the other malignant solid tumors reduction in tumor size was recognized. Decrease in CEA level occurred in 88 percent of the cases with metastatic liver cancer and lung cancer. Major side effect was transient fever in about 50% of cases. Mitomycin C and aclarubicin dissolved in lipiodol showed remarkable antitumor effects for experimental liver cancer.
