[Clinicopathological comparison between well-differentiated and poorly differentiated gastric cancer].
Among 664 patients who underwent surgery in our hospital during the period between 1972 and 1981, 185 (27.9%) were classified into the well-differentiated type (group WD) and 310 (46.7%) into the poorly differentiated type (group PD). There were significant differences between the two groups in age, sex, location of tumor, etc. Early cancer was more common in group WD than in group PD. The prognosis changed according to the depth of tumor invasion. In cases of positive serosal invasion, the five-year survival rate was higher for group WD than group PD without significant difference.
