[Clinico-pathologic study on extended radical resection for rectal cancer].
OBJECTIVE
To justify clinico-pathologically the extended radical resection for rectal cancer.


METHODS
Resected lymphatic specimens obtained by the triple approach in the radical resection for advanced rectal cancer was studied by routine pathological method. The outcome of this extended radical resection, guided by the route of lymphatic metastasis are presented in the justification.


RESULTS
The incidence of lymphatic metastasis in advanced rectal cancer in the Chinese was 45.0%, with 44.0%, 14.0%, 10.0% and 9.0% in the upper 1, 2, 3 and the lateral third groups. Lymphatic metastasis from rectal cancer was related to the extent, depth and pathological type. The 5- and 10-year survival rates were 68.0% and 47.0%, which are much higher than those of the conventional radical resection.


CONCLUSIONS
Extended radical resection for the rectal cancer, removing all the lymphatics, is able to prevent possible metastasis, thereby improving the survival rate significantly, This extended radical resection is an optimal type of operation.
