[Increased incidence of malignant tumors of the nose and nasal sinuses in workers in the wood industry and other occupations].

In the period of 1958-1979 in the files of National Cancer Register (NCR) of GDR 1,313 patients with nasal cancer (ICD 160) were registered in seven districts of the GDR. In collaboration with NCR the occupational history of 1,160 patients with nasal cancer was recorded by a questionnaire. The results suggest an increased number of tumors in several professions. Compared to about 19 expected tumors in male woodworkers the number of the observed was 70. This is a statistical significant risk of 3.6.
