ABSTRACT
PURPOSE:
The aim of this study was to clarify the clinicopathological differences between T1N1M0 and T2N0M0, particularly the survival rates, and the role of chemotherapy in the stage Ib gastric cancer.METHODS:
From January 1992 to December 1999, 118 cases were confirmed as having stage Ib gastric cancer in the Korea University Medical Center. Among them 31 patients were classified as being T1N1M0 and the other 87 cases were T2N0M0. The clinicopathological features and the prognosis were evaluated retrospectively.RESULTS:
The overall 5-year survival rate of the stage Ib gastric cancer patients was 94%. Overall 5-year survival rates in T1N1M0 and T2N0M0 were 100% and 91%, respectively. Though T1N1M0 group showed better prognosis, there was no significant difference between two groups (P=0.14). D1, D2, and D2+alpha resections were performed in 28 cases (23.7%), 81 (68.6%), and 9 (7.6%), respectively, and there was no difference in the survival rate (P>0.05). The 5-year survival rates were analyzed according to whether or not they had received chemotherapy. There was a 98% 5-year survival rate with those who had chemotherapy and a 90% 5-year survival rate with those who had not had chemotherapy, but there was no significant difference between them (P=0.18). In the T2N0M0 group, the 5 year survival rates of patients with or without chemotherapy were 97% and 86%, respectively, but there was no significant difference (P=0.16).CONCLUSION:
Though T1N1M0 group showed a better prognosis than the T2N0M0 group, there was no significant difference between the two groups (P=0.14). There was no significant survival difference between D1, D2, or D2+alpha procedures. It appears that post operative intravenous chemotherapy does not affect the prognosis of stage Ib gastric cancer, and the role of the chemotherapy in patients with T2N0M0 diseases is minimal.
