[Behavior of T-lymphocytes in patients with a gynecologic malignancy]

The proportion of T-lymphocytes was estimated by the alpha-naphthylacetate-esterase-reaction as a T-cell marker in blood smears of 40 patients with gynecologic malignancies and 30 healthy controls. In addition the red and white blood cell counts were determined. A lymphopenia and a reduction of T-lymphocytes were found in the peripheral blood of the tumorgroup, on the other hand the number of B-lymphocytes was elevated in this patients. This method of lymphocyte differentiation may be of value for controls in patients suffering from malignant tumors.
