Thirty one cases of coecum cancer were operated in our department of surgery during the period from 1956 to 1978. Among them, 9 cases had recieved appendicectoiny or drainage owing to misdiagnosis about 10 months on an average before the cancer operation. They consisted of 5 males and 4 females with an averagee age of 45:5 years. In the appendicectomized group, the mean survival time of coecum cancer except for the alive was 17 months, whereas 29 months in the non-appendicectomized group. The histopathological study of resected specimens revealed the weaker stromal reac-tion with a smaller number, of peripheral lymphocytes in the former group than the latter. The results obtained suggest that appendicectomy may adverse influence on the deve-lopment and prognosis of coecum cancer. More attention has to be paid therefore to differentiate coecum cancer from appendicitis at the time of the operation.
