TS, DPD and OPRT are the key enzymes on the metabolic pathway of 5-Fu. We will retrospectively analyze the clinicopathological features of the patients who have suffered an inoperative or recurrent gastric cancers and administrated with S-1, such as the overall survival (OS), progressive-free survival (PFS), Lauren's classification and toxicity of S1, etc. We will divide the patients into several subgroups according to the parameters above, and then investigate the correlation between the parameters and the expression of TS, DPD and OPRT.
