✦ Synopsis

A total of 239 determinations of CEA plasma levels were performed for 83 breast cancer patients during chemotherapy or follow-up. In addition, 137 plasma samples were assayed for interferon levels. Patient clinical status was carefully scored according to objective criteria and recorded at each evaluation. Liver function tests (LFT) were performed to establish a full clinical picture at each visit. The results obtained proved a 73 to 83 % positivity rate when the results of the 4 tests were compared. The importance of routine CEA assays and careful clinical evaluation and LFT are stressed. An analysis of interferon levels defined 4 distinct groups that differed by the amount of interferon present and also by clinical status and CEA levels. The results are discussed in terms of tumor volume-dependent interferon production.

Carcinoembryonic antigen (CEA) levels were determined in 742 postoperative patients with breast cancer. Within this group the percentage of elevated (24.0 ng/ml) assays increased with UICC clinical stage and was 14.8% (12/81), 23.7% (27/114), 73.1% (190/260) and 20.0% (49/245) for stages I, 11, 111,

Serial plasma CEA levels were determined over a period of 1-3 years in 114 patients receiving adjuvant chemotherapy for T1, 2 or 3a N+ MO breast cancer. CEA values were correlated with clinical status, scintiscans, and other biochemical parameters. CEA values >2.5 ng/ml were considered abnormal. For

We studied the immunoreactivity by immunohistology of two carcinoembryonic antigens (CEA) with specific and two CEA antibodies with nonspecific cross-reacting antigen (NCA) cross reactivity (CEA/ NCA) in 180 primary breast carcinomas. Positive tissue staining was found in more than 90% of the specim
