PRIMARY-CARCINOMA OF THE GALLBLADDER - POTENTIAL FOR EXTERNAL RADIATION-THERAPY

Nineteen patients (14 women, 5 men) received external radiation therapy (ERT) between 1980 and 1988 for gall-bladder carcinoma. Eleven patients had complete resection (cholecystectomy in eight cases), six incomplete gross resection and two only percutaneous transhepatic biliary drainage (PTBD). The modalities of ERT were variable and doses ranged from 30 Gy/10 fractions to 50 Gy/25 fractions. Among 11 patients with complete resection (9/11 with T1 or T2 stages), overall survival was 55% at 48 months and 36% at 60 months, median survival was 48 months and at the time of this report 3/11 patients were alive with no evidence of disease, 54, 65, 76 months after surgery, and eight dead of cancer 8-114 months. Local control was achieved in 66 patients with T1 or T2 stages. All eight patients who had palliative surgery or PTBD died of cancer after 4-20 months with median survival of 6 months. Three complications were noted: one gastric ulcer in the course of ERT (surgical treatment), one duodenal ulcer which occured 6 months after completion of ERT (medical treatment) and one regressive radiation hepatitis. From this experience it appears that ERT in gall-bladder carcinoma is well tolerated, can obtain local control and prolonged survival after complete resection and good palliation in non-resectable tumors.
