freshly isolated cells from patients with pleural or peritoneal effusions cytologically diagnosed as adenocarcinoma ( n = 43 ) , malignant nonepithelial neoplasms ( n = 10 ) , and benign ( n = 8 ) were analyzed for expression of constitutive levels of the tumor antigens tag-72 [ recognized by monoclonal antibody ( mab ) b72.3 ] and carcinoembryonic antigen ( cea ) ( recognized by mab col-4 ) as well as the class i and class ii major histocompatibility ( mhc ) antigens , and the ability of human interferons ( hu-ifns ) to enhance cell surface expression of those antigens as measured by mab binding .
