Abstract
Serum carcinoembryonic antigen (CEA) levels were determined for 439 patients with squamous carcinoma of the head and neck region, 154 healthy smokers, and 122 nonsmokers. Among nonsmokers 95% of the CEA levels did not exceed 5 ng/ml, but among smokers this discriminatory level was 7 ng/ml. Among tumor-bearing patients 36% of the CEA levels exceeded 5 ng/ml but only 17% exceeded 7 ng/ml. Both the incidence and magnitude of CEA elevations correlated with clinical stage of tumor; however, excluding patients with clinically apparent advanced malignancies, the incidence and magnitude of elevations were similar among tumor-bearing patients, tumor-free treated patients, and smokers. Although not predictive of ultimate survival, elevated preoperative CEA levels declined to the range of normals after resection. Similarly, during palliative irradiation for incurable tumors, CEA levels declined with regression of tumor. Irradiation did not nonspecifically elevate CEA levels. The data indicate that in patients with head and neck squamous carcinomas CEA level is not likely to contribute to a determination of prognosis after therapy; however, serial determinations may have adjunctive value in monitoring tumor response.This publication has 19 references indexed in Scilit:
