Abstract |
Ca1 antibody reacted focally with all of the 20 cancers examined, but also with 12 out of 13 fibroadenomata and with each of 20 normal breasts. These observations indicate that there are severe limitations to the use of Ca1 antibody for defining benign versus malignant processes. Ca1 is most specific in terms of the cytoplasmic staining of tumours versus normal tissues. If a hierarchy of maximal staining is drawn up, cancers and fibroadenomata appear at the top, with normal tissue found in various types of breast in the middle, and non-neoplastic lesion such as epitheliosis, hyperplasia and apocrine change at the bottom of the hierarchy. There is a growing list of non-cancerous tissues which show reactivity to Ca1. In July 1983 this list numbered about 15. The designation 'Ca' is inappropriate.
