Patent ID: 8071286

Claim:
A method for predicting the likelihood of long-term survival without recurrence of breast cancer comprising: amplifying an RNA transcript from a tissue sample obtained from a primary ductal or lobular breast tumor of a human patient with at least two primers capable of amplifying a GSTM1 RNA transcript, wherein said primers comprise about 18 to about 27 bases of SEQ ID NO: 306, or a complement thereof; producing an amplicon detectable by an oligonucleotide probe having a sequence consisting of a sequence of SEQ ID NO: 306, or a complement thereof, under stringent hybridization conditions; assaying a level of the amplicon; normalizing said level against a level of at least one reference RNA transcript in said tissue sample to provide a normalized RNA level; and predicting the likelihood of long-term survival of said patient without recurrence of breast cancer by comparing said normalized RNA level to expression data of the amplicon obtained from reference breast cancer samples, wherein an increased normalized RNA level is positively correlated with an increased likelihood of long-term survival without breast cancer recurrence in said patient.
