Gastric cancer: cancer vs. normal, chemoresistance signature that correlates with time to progression of disease

ABSTRACT: microRNA profiling of gastric cancer vs. normal, pre-/-post CF (cisplatin/fluorouracil) chemotherapy. Biopsy samples were collected prior to chemotherapy from 90 gastric cancer patients treated with CF and from 34 healthy volunteers. At the time of disease progression, post-treatment samples were collected from 8 clinical responders. miRNA expression was determined using a custom-designed Agilent microarray. In order to identify an miRNA signature for chemotherapy resistance, we correlated miRNA expression levels with the time to progression (TTP) after CF. 90 pre-treatment gastric cancer samples, 34 healthy volunteers, 8 post-treatment samples.
