[Relationship between surgery, chemotherapy, irradiation and immunological state in patients of laryngeal cancer (author's transl)].

The relationship between surgery, chemotherapy, irradiation and the immunological state in patients of laryngeal cancer with or without metastasis was investigated. The lymphocyte reaction to PHA (Phytohaemagglutinin) stimulation and T-lymphocyte count was examined before and immediately after the therapy in 66 patients divided into three groups. From the results the authors conclude that surgical treatment (partial or total laryngectomy, with or without radical Neckdissection influence the immunological state of the patients at least, chemotherapy more and irradiation at most.
