Abstract
beta2m was determined by radioimmunoassay in 43 serums from healthy blood donors. Serum concentrations varied from 0.67 to 1.9 mg/l with a mean of 1.29 mg/l. Reproductibility and sensitivity of the method were evaluated. 66 patients with advanced neoplasia were studied. Serum beta2m was greater than 2 mg/l in 70% of the cases and carcinoembryonic antigen (CEA) in 54%. In 26 documented cases with tumor progression and 14 with regression, associated variations of CEA were formed more frequent and of greater magnitude than those of beta2m.
