Immunohistochemical distribution of mucinous-like carcinoma associated antigen (MCA) in breast and non-breast cancer: comparison with other biological parameters.
|
| Abstract |
The present study reports the immunohistochemical reactivity of the monoclonal antibody b-12 (MAb b-12) with malignant human tissues. 173 neoplastic tissues were tested: MAb b-12 stained all breast carcinomas independently of their histology, with different patterns within the various type of cancer. Some other carcinomas (stomach, bowel, ovary, lung, endometrium), were also reactive even if the fraction of positive cells was lower. A comparison between the histological localization of MCA and that of CEA was performed; anti-CEA antibodies stained the cancer tissues with different reactivity and showed different percentages of positivity. MCA expression was also compared with other biological parameters such as the presence of estrogen receptors (ER), progesterone receptors (PgR), epithelial growth factor receptors (EGF-R), and oncoprotein p-53 which is encoded by the oncogene N-myc. The proliferative activity was also evaluated by measuring the growth fraction (GF) using the antibody Ki67. Any correlation was demonstrated between MCA and these parameters except for growth fraction as revealed by Ki67 antibody.
