73 women suffering from primary carcinoma of the fallopian tube underwent surgical excision of their tubes. The tissue was embedded in paraffin and investigated for HER-2 oncogene amplification with a quantitative polymerase chain reaction method. DNA could be extracted and successfully prepared in 65/73 samples. None of the tissue samples exhibited amplified the HER-2 oncogene. Data suggest that the HER-2 oncogene does not play a role in tumor transformation and progression in fallopian tube carcinomas. This contrasts with observations in ovarian carcinomas, with which fallopian tube carcinomas share many clinical, histological and biochemical similarities.
