Abstract

Our study deals with a lot of more than 50 patients with breast cancer disease and is lasting by more than two years. The values of the antigens CA15-3 and TPS were recorded both before and after the exposure of the human serum to ultrashort UV-A laser pulses. Our conclusion is that the number of pulses does influence the TPS values while the CA15-3 seams to be more robust and stable. The temporal distribution of UV energy is an important control parameter. The results are compared with those of a healthy sample. The pulse energy is correlated with the determinations. Our study is important for designing a novel monitoring scheme for patients subjected to crossing type laboratory analyses..
