The neural cell adhesion molecule (NCAM) is a tumourrelated antigen found on the surface of small-cell lung cancer (SCLC). NCAM exists in several molecular forms, including a soluble isoform. We have measured serum levels of NCAM using an enzyme immunoassay with 2 anltibodies, NCC-LU-246 and NCC-LU-

β¦ Synopsis
We report that the Rhesus (Rh)-negative phenotype is more prevalent in patients with small-cell lung cancer (SCLC) than in the normal Caucasian population (SCLC: 25% Rh-negative vs. 15% expected, p < 0.000 I). This finding has been validated for a Central and a Northern European population (Switzerland and UK). In contrast, the Rh-negative phenotype is no more frequent in non-small-cell lung cancer patients or in heavy smokers with coronary heart disease than in the general population. There was a normal distribution of the ABO blood group phenotype in all patients studied. Whilst the significance of this observation is unclear, we hypothesize that a genetic predisposition to the development of SCLC may be linked to a hitherto unidentified gene on chromosome I p near the Rh locus. Our observation may perhaps allow further progress to be made in understanding genetic mechanisms of SCLC carcinogenesis.
