Expression of blood group-related antigens in neoplastic uterine cervix.

Expression of blood group antigens in normal, displastic and tumoral uterine cervix from 35 hysterectomised women with carcinoma of the cervix was investigated; the results were correlated with patients' ABH phenotype and secretor status. We used an indirect immunoperoxidase technique and a panel of monoclonal antibodies and lectins directed against different antigenic specificities. Anomalous expression of blood group antigens in premalignant lesions from cervix was found.

[Importance of E-cadherin; expression in the inmunohistochemical diagnosis of breast cancer].

It has been propossed that 50% of lobular carcinomas (LC) may change their phenotype to ductal carcinoma (DC) in 20 years. Since the prognosis and treatment of both breast carcinomas is different, it seems to be important; investigate through immunohistochemistry the loss of E-cadherin expression. E-cadherin expression was investigated in 90 cases with diagnosis or histological appearance of LC or mixed carcinomas (MxC), and in 30 DC selected among 385 cases received during year 2005 to be examined for immunohistochemical diagnosis.
