		27:	Squamous cell carcinoma antigen in the diagnosis and treatment follow-up of oral and facial squamous cell carcinoma.
			著者: W Fischbach, T Meyer, K Barthel 雑誌名: Cancer. 1990 Mar 15;65(6):1321-4. Abstract/Text The squamous cell carcinoma (SCC) antigen was determined by radioimmunoassay in the serum of 40 untreated patients with SCC of the oromaxillofacial region. The mean (+/- SEM) serum concentration for these patients (3.8 +/- 0.8 ng/ml) was significantly higher than that of 52 disease-free patients coming to routine postoperative care (1.2 +/- 0.1 ng/ml) and of 74 healthy controls (1.1 +/- 0.07 ng/ml). Using a arbitrary limit of 2.2 ng/ml, pathologic serum levels of SCC were observed in 15 (38%) of 40 untreated patients, whereas only four (7.7%) of 52 tumor-free patients revealed an elevated serum SCC. Serial measurements of SCC were pretherapeutically available in 28 patients as well as during individual therapy and further follow-up. All but one of these patients had a normal serum SCC postoperatively. The authors' results demonstrate that the clinical value of SCC lies mainly in monitoring the course of the disease. Careful follow-up studies should be undertaken to determine whether serial determination of SCC is promising in early prediction of tumor reoccurrence. PMID 2306680 Cancer. 1990 Mar 15;65(6):1321-4.
