Carcinoembryonic antigen and skin test reactivity in tumor radiotherapy.
Serial carcinoembryonic antigen (CEA) levels were obtained from 122 cancer patients. In a random selection, the levels in 67 of these patients were compared with clinical response to radiotherapy. Skin tests were also performed for histoplasmin, tuberculin and mumps. CEA levels, skin-delayed hypersensitivity reaction (DHR) and clinical tumor response were evaluated and correlated. Clinical response of tumors to radiotherapy was more often seen in patients with positive skin tests, but no correlation was observed between skin test reactivity and CEA response curves.
