[Study of 2 markers, keratin and neuron-specific enolase, in bronchial cancers].
In an immunohistochemical study 31 patients with bronchial cancer (squamous cell 9, large cell 4, small intermediate cell 11 and oat cell 7) were investigated for keratin and NSE. Keratin seems to be a valuable marker since only oat cell cancers and 45% of small intermediate cell cancers were negative. In contrast, marking with NSE seems to be non-discriminating. The low value of NSE as marker was confirmed by 133 serum NSE assays performed in 39 bronchial cancer patients. Although NSE values were significantly higher in oat cell cancer, in any given patient serum assays can, at best, detect relapses.
