Molecular Marker of Tumours

Molecular structure of the marker of tumour is determined by magneto-optical analysis of blood serum. The marker is the laevorotatory enantiomer of alanine. The cancer status of a subject is described by the number of molecules of the laevorotatory alanine enantiomer ^(-)ρ and the effectiveness of therapy is measured by the number of molecules of the dextrorotatory alanine enantiomer ⁽⁺⁾ρ. The values of ^(-)ρ and ⁽⁺⁾ρ are determined separately for the patient before and after therapy.
