Serum deoxythymidine kinase in small cell carcinoma of the lung: Relation to clinical features, prognosis, and other biochemical markers

Abstract
Thymidine kinase (s‐TK), lactate dehydrogenase (LDH), and carcinoembryonic antigen (CEA) were determined in pretreatment serum from 125 patients with small cell carcinoma of the lung. The distribution of marker levels into three ranges, when including all patients were as follows: s‐TK Cancer 58:111–118, 1986.
