The superselective and the selective one shot methods for treating inoperable cancer of the liver.

Forty-five patients with inoperable cancer of the liver were treated by the one shot administration of 15-40 mg of Mitomycin C into the hepatic artery, either by the superselective or by the selective one shot method. Fourteen of the patients had primary cancers of the liver, and 31 had metastases to the liver from primary cancers of the stomach, or from the colorectal or other organs. Subjective symptoms improved in 73%, and objective signs improved in 60%. Nineteen patients who received this treatment more than twice showed a mean survival time of 10 months and a 50% survival time of 7.8 months. Therapeutic effects of the selective one shot method were recognized mostly in patients with tumors which were rich in vessels. However, a fairly good result was obtained using the superselective one shot method, even in patients with tumors having relatively few vessels.

Clinical effects of anticancer drugs to pancreatic diseases as protein synthesis inhibitors.

The anticancer drugs, like 5-Fluorouracil, which are believed to interfere with enzyme protein synthesis in the exocrine cells of pancreas were administered intravenously to fifteen patients with various pancreatic diseases. The improvement of clinical symptoms and the diminution of serum and urinary amylase levels were observed in four cases with acute pancreatitis and two cases with chronic relapsing pancreatitis. The postoperative complications, namely the formation of pancreatic fistula and the rupture of pancreaticojejunostomy, or the aggravation of concomitant pancreatitis were not observed in three cases with benign surgical pancreatic diseases and six cases with pancreatic carcinoma. Furthermore, the diminution of amylase and protein output of pancreatic juice from canulae inserted into pancreatic ducts were observed.

Bile acid load on the DNA distribution pattern of bile ductules and cholangiocarcinoma induced by diisopropanolnitrosamine in hamsters.

This study evaluated the influence of bile acid load on the DNA distribution pattern of proliferated bile ductules and cholangiocarcinoma induced by diisopropanolnitrosamine. Ninety hamsters were separated into control, tauro- and deoxycholic acid (DCA) groups. The DNA distribution pattern of intrahepatic lesions at 15-25 weeks was measured by cytofluorometry and classified into three types: I (-A, -B), II and III, according to the degree of dispersion on the DNA histogram. Regarding proliferated bile ductule lesions, all groups showed an increase in cell populations, indicating the dispersion of nuclear DNA content from the 4C to 6C ranges over the course of 25 weeks, and two groups with bile acids, especially the DCA group, revealed significant high incidences of lesions with type I-B plus II compared with those in the control group (p < 0.05, 0.01). Changes in carcinoma types were similar to those of bile ductule lesions, and the tumors in the DCA group had a significant high frequency of type II plus III (p < 0.05). In addition, heterogeneity of the DNA distribution pattern was observed within individual lesions of not only carcinoma but also bile ductules. These results suggest that bile acid load, especially DCA, promotes an increase in nuclear DNA content or DNA polyploidization and enhances the distribution of the DNA pattern of proliferating bile ductules and carcinoma. Furthermore, a bile ductule-carcinoma sequence may be present in the development of cholangiocarcinoma.
