Background:
It has been reported that we should give consideration to death caused by other disease from comparison between overall survival(OS)and disease specific survival(DSS)in several studies.
Patients And Methods:
Relationships between the clinicopathological features of OS and DSS were examined among 197 patients undergoing surgery for gastric cancer.
Results:
In OS analysis, the Charlson comorbidity index(CCI), pathological T and postoperative complications with Clavien-Dindo Grade≥Ⅲ were associated significantly in multivariate analyses(p=0.009, 0.022, 0.027). On the other hand, in DSS analysis, CCI was not associated, but gender, DG/TG, pathological N and complication were associated significantly( p=0.0002, 0.016, 0.0003, 0.009).
Conclusion:
The complication is a significant prognostic factor of OS and DSS in gastric cancer patients. It is important to pay attention for comorbidities and to prevent the postoperative complications in order to improve the prognosis in gastric cancer surgical therapy.
