In the period of 1990-1992, 238 patients underwent surgical treatment for laryngeal carcinoma in ORL Department of Medical Academy in Białystok. Until now 27 cases of second primary malignances (SPM) have been found in this group (11.3% of the screened population). Upper aerodigestive tract was the most frequent location, i.e. it was observed in 18 cases (66.6%). There was 100% mortality among patients with SPM of stomach, oesophagus and lung estabishing 13% deaths in the whole group. There was no correlation between the stage and the location of primary laryngeal cancer and SPM.
