Abstract
The authors carried out immunological investigations in 96 patients with laryngeal cancer. The following tests were applied: DNCB, PPD, phytotest and the lymphocyte count. The patients were divided into three groups: 1) cured, one year following treatment; 2) relapses; 3) died during the first year. The separate group of 13 patients tested twice in first year was analysed too. The immunological tests were also performed in 24 patients with no relapses of laryngeal cancer in the period between 3 and 10 years after treatment. This group was used for a comparative analysis with laryngeal relapses. In our opinion each individual test has its relative merit. According to our results patients with normal and elevated test values have the best prognosis of cancer disease.
