title: Isolation and characterisation of adenoid squamous carcinoma cells highly producing SCC antigen and CEA from carcinoma of the maxillary sinus.
abstract: A serially transplantable adenoid squamous carcinoma tumour line (SCCMM) derived from carcinoma of the maxillary sinus of a 56-year-old male with high serum levels of SCC antigen (SCC-Ag) and carcinoembryonic antigen (CEA) was established in athymic nude mice. Nude mouse tumours produced by transplantation of operated material showed similar histological features to those of the original tumour and expression of SCC-Ag and CEA immunohistochemically. In addition, SCC-Ag and CEA in sera of tumour-bearing nude mice were detected at high levels in proportion to the relative tumour weight. The primary cultured tumour cells demonstrated the expression of SCC-Ag and CEA and the production of these antigens into culture medium. The serum levels of these tumour antigens were decreased concomitant with tumour regression by antitumour drug administration. Therefore, this tumour line and its cultured cells could provide a useful model for investigation of the relationship between tumour growth and expression of these tumour antigens.
