Amplification of ERBB-2 (HER-2/NEU) oncogene in different neoplasms of patients from USSR.
203 tumor specimens from 175 patients were studied. Amplification of ERBB-2 was detected in 14 out of 63 (22%) cases of breast carcinoma, in 1 out of 23 patients with ovarian cancers, in 1 out of 19 cases of colon carcinoma and in 1 out of 27 patients with thyroid cancer. We failed to find more than one copy of ERBB-2 in 34 patients with lung cancers, 6 with sarcomas and 3 with melanomas. There was tendency toward correlation between ERBB-2 amplification and lymph node involvement in patients with breast carcinoma. Thus, the oncogene ERBB-2 is often amplified in human tumors, but breast cancer is characterized by an especially high frequency of ERBB-2 amplification.
