DNA ploidy, histological grade, and immunoreactivity for carcino\u2010embryonic antigen (CEA), carcino\u2010embryonic antigen with normal cross\u2010reacting antigen (CEA\/NCA), and to NCRC\u201011 were assessed in primary breast carcinomas and metastases from the ovary and axillary lymph nodes. Changes in these variables between primary tumours and their metastases were found in 44 per cent of cases for DNA ploidy, 44 per cent of cases for histological grade, 17 per cent of cases for immunoreactivity to NCRC\u201011, 28 per cent of cases for CEA, and 56 per cent of cases for CEA\/NCA immunoreactivity, respectively.
