Pathologic Study on Carcinomas of Extrahepatic Biliary Tract

The authors reviewed surgical materials from 20 patients with carcinoma of the extrahepatic biliary system, and a correlation between macroscopic appearance of the tumors with various clinical features and histopathologic findings was made. Microscopically, the tumors were classified into four types; Four (21%) patients had polypoid tumors, six (32%) had nodular growths, five (26%) were scirrhous constricting in type, and four (21%) had diffusely infiltrating type. Histologically all the differentiation in two cases. The degree of differentiation of the tumors was classified into 3 types: 11 (55%) patients were well differentiated, 3(15%) were moderately well and 6(30%) were poorly differentiated. All polypoid tumors were well differentiated and had low stage. No correlation in the degree of differentiation of the tumor with the stage was present. No correlation in clinical symptoms, duration of symptoms, laboratory findings with morphologic findings of the tumors was noted.

Transcatheter Irradiation of Advanced Extrahepatic Biliary Tract Carcinoma / 대한치료방사선과학회지

Carcinoma of extrahepatic biliary tract is slow growing tumor but curative resection is rarely successful, Radiation therapy has been introduced for enhancing palliation and possible longterm survival. We treated a case of advanced extrahepatic biliary tract carcinoma with high dose rate remote afterloading system through T-tube as a initial irradiation postoperatively. We hope that this treatment may affect not only ennancing palliation and better quality of life but also in local tumor control.
