Summary
The intensity of cortisol binding was measured in the cytosol fraction of the primary tumor obtained from 50 patients with stage I and II breast cancer. The state of cellular antitumor immunity of the same patients was investigated by the tube leucocyte adherence inhibition (LAI) test, performed with peripheral blood leucocytes 1–2 days preoperatively. It was found that the intensity of tumor cortisol binding correlates negatively with LAI values. Patients with high cortisol binding in their tumors have low LAI values, while low tumor cortisol binding is associated with higher antitumor immunity. The results suggest that high cortisol binding in the tumor might inhibit the tumor recognition process and/or the cellular immune defense mechanism and thus facilitate cancer development.
