Problems of radical operation for gallbladder cancer-mode of cancer spread and prognosis

Abstract

The results of thirty nine resected cases with gallbladder cancer were investigatd. The cumulative survial rate of 1,3 and 5 years in all resected cases were 68.0, 50.3 and 50.3%. The 3 year survival rate in early cases whose cancer was confined to the mucosal or submucosal layer, in moderate cases and in advanced cases whose cancer has infiltrated the serosal layer were 100, 66.2 and 14.7% and that in curative cases, relativ nonculative cases and absolute nnculative cases, all which were judged histologically, were 90.9, 100 and 0%.
These results demonstrated that when the extented radicall opration wa s performed aiming for the curative or relative nonculative operations in stead of the absolute nonculative operation, the best opportunity for cure was obtained.
