Effect of radiotherapy on the neutrophil and the lymphocyte enzymatic equipment and serum immunoglobulins in patients with cancer of the larynx.
In 30 patients with cancer of the larynx, aged 40 to 70 years, treated by radiotherapy 6 to 9 years ago the decreased activity of neutrophil beta-glucuronidase and N-acetyl-beta-glucosaminidase accompanied by a decrease of absolute count of enzyme-positive cells was noted. Numbers of acid phosphatase-positive neutrophils were also decreased. Moderate increase of the neutrophil alkaline phosphatase activity and of numbers of enzyme-positive cells was another observed feature. The main finding in lymphocytes of the patients consisted in the appearance of cells exhibiting diffusion of lysosomal enzymes, especially of beta-glucuronidase, N-acetyl-beta-glucosaminidase and to a lesser degree of acid phosphatase into the cell cytoplasm. Moderate increase of immunoglobulin level, especially that of IgA, reflected probably the immunologic mobilization of patients.
