title: [Multiple malignant tumours in patients with laryngeal cancers (author's transl)].
abstract: Of 496 patients with laryngeal cancer, 45 developed second primary cancers in other organs. In 7 patients triple primary tumours were detected. Multiple malignant tumours in the region of the upper respiratory and alimentary tracts were frequent; especially noticeable was the combination of larynx- and lung tumours. The prognosis of the second cancers is bad, since these tumours are diagnosed late and the patients are usually very old. Of patients, who were cured of the first cancers, one in five developed a new cancer after the five year limit. The follow up examinations must therefore be continued beyond the five year limit.
