[Clinical course of laryngeal cancer in relation to sex]

In 1960-1987 2352 cases of larynx cancer were cured and observed. The number of the side men to women was in the ratio of 11.5:1. The cancer of epiglottis was prevailing in both sex but percentage of these cancers was higher in women's cases than men's (67.6% vs 62.7%). Besides women called for the treatment more often with the cancer in initial states of the disease (62.2% vs 53.4%). Five--year survivals (actuarial method) were higher amongst women (69.8% vs 60.0%). In the same state of clinical advancement of the disease, the 5-year survivals were also higher with women. In the cases of cancer in the early states of larynx cancer (I and II) the difference was about 5.0%, and among patients with cancer in the late state of the disease (III and IV) the difference was 8.4%. The last premise caused the authors to put forward the hypothesis that apart from the sooner calling for the treatment of women, there may also be other unknown phenomena, perhaps hormone--immune, conditioning higher index of survivals in women.
