    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.

    摘要: Disclosed is a method for detecting the degree of malignancy in tumors noninvasively, which comprises the steps of: using a Power Doppler ultrasound unit to scan a tumor and capture sequential color imagines in a complete heartbeat cycle, and choosing an area of interest (AREA_ROI) from the images; labeling pixels reflecting signals of bloodflow in the imagines during one heartbeat cycle to contour an area of tumor blood vessels (AREA_vessel); calculating a difference of PDVI between maximal systolic pressure and diastolic pressure during the heartbeat cycle to obtain tumor differential vascularity index (TDVI), in which PDVI is the ratio obtained by dividing pixels of AREA_vessel by a total area in the section of AREA_ROI; and determining the degree of malignancy by the TDVI. The method of the present invention can be applied to monitor the response of tumor to clinical treatment.
