The ETV6/TEL gene encodes a transcription factor frequently rearranged in several types of cancer. We looked for ETV6 rearrangements in invasive breast cancer using fluorescence in situ hybridization (FISH) of BAC probes on sections of tissue microarrays containing 632 tumor samples. Of these samples, signal of sufficient quality for screening by FISH was obtained for 356. Five cases (one lobular, one nontypical secretory, one mixed, and two ductal carcinomas) showed ETV6 rearrangement.
