Using FISH, they observed that 4 of the 10 cases that were analyzed showed HER2/neu gene amplification. They, however, observed no differences in prognosis between amplified and nonamplified tumors. p53 positivity was found in 58% of SDCs studied by Felix and colleagues 251 but did not correlate with the clinical course.

HER2 gene copy number is specified, and the HER2/chromosome 17 ratio is reported; a normal HER2/chromosome 17 ratio is equal to or less than 1.7 2020-10-06 Home; Fish > Her2 Neu Fish 2020-01-21 5 With FISH testing, the results are quantitative instead of qualitative; tumors are interpreted as HER2 "negative" or "positive" by enumerating the HER2/neu gene copy number. 2020-06-06 This means that the HER2 status needs to be tested with FISH to clarify the result. Triple-negative breast tumors don’t have too much HER2 and also don’t have estrogen or progesterone receptors. They are HER2-, ER-, and PR-negative. Using FISH, they observed that 4 of the 10 cases that were analyzed showed HER2/neu gene amplification.
