  • TREATMENT OF LIVER CANCER WITH 32P GLASS MICROSPHERE——AN EXPERIMENTAL STUDY

    Four pigs underwent the hepatic arterial infusion with 32P glass microsphere (32PGM) and pigs were killed in 15th, 30th and 90th days separately. Pathological study showed that in early stage there were many small necrotic areas scattered along the hepatic arterioles. Three months later, these necrosis were gradually absorbed and replaced by regenerating hepatic cells. Tumor-inhibition experiment was performed in 40 Bal B/C mice bearing H22 hepatoma. Intratumoral injection of 0.2ml of 32PGM/glycerine suspension (group A, n=20) or 0.2ml of blank glass microsphere/glycerine suspension (group B, n=20) were performed. The average survival time in group A and group B was 24.8 and 11.8 days respectively. Five mice in group A were alive beyond 40 days after treatment, disappearance of tumor was found in two of them. This experiment demonstrates that 32PGM is effective for treatment of experiment hepatoma. The damage to hepatic tissue after infusion is associated with the irregular distribution of microsphere, and this lesion can completely recover within three months.
