Gene relating to estimation of postoperative prognosis for breast cancer

Abstract

It is intended to provide a system of predicting the postoperative prognosis in a patient with breast cancer from the viewpoint of gene expression based on the data obtained by genome-wide and comprehensive analysis on gene expression in breast cancer. Expression of human genes is comprehensively analyzed by using a DNA microarray and gene expression functions in various breast cancer conditions are compared, thereby establishing a system of predicting the postoperative prognosis of breast cancer.

1 - 19 . (canceled) 
     
     
         20 . A method for predicting a postoperative prognosis in node-negative (n0) breast cancer with no metastasis to a lymph node in operation, comprising measuring an expression of galectin 1 gene. 
     
     
         21 . The method of  claim 20 , wherein the measurement is performed by using galectin 1 gene and/or a probe specific thereto. 
     
     
         22 . The method of  claim 21 , wherein the galactin 1 gene/and or the probe are carried on a DNA microarray. 
     
     
         23 . The method of  claim 22 , wherein the DNA microarray is a fiber type array. 
     
     
         24 . The method of  claim 21 , wherein the measurement is performed using the galectin 1 gene.
