摘要
Disclosed is a method for survival prediction in gastric cancer patents after surgical operation, which uses a survival prediction model determined by known statistical method and gene expression microarray profiles. The survival prediction model is established by selecting special genes expressing significantly differential from pairs of cancerous and noncancerous tissue samples from patients with known survival conditions after surgical operation, confirming the concordance of RT-PCR analysis with the microarray gene expression profile, identifying most specific genes among the special genes using a statistical method, and determining the survival prediction model based on training set samples. The method of the present invention can be applied in gastric cancer patients to predict survival conditions after surgical operation and to provide a strategy for succeeding treatment and a reference for adjuvant chemotherapy.
