The association of cancers of the larynx with cancers of the lung.

We report 77 cases of associated primary cancers of the larynx and lung that were managed at the Department of Otolaryngology, University of Padua, between 1980 and 1994. To our knowledge, this is the largest series reported in the literature to date. This association is not a chance finding, but presumably the result of common pathogenetic factors.
