A preliminary analysis of end results for cancer of the larynx

Abstract

Abstract Information from 23 different treatment centers, for a total of 10,989 cases of laryngeal cancer, has been assembled. It has been possible, so far, to present only a preliminary survey and initial analysis of the material collected; however, despite its imperfections, this study has highlighted some features which are worthy of comment: There are marked geographic differences in the relative frequencies of supraglottic versus glottic cancer. The low incidence of lymph node metastases in glottic cancer has been abundantly confirmed. The bulk of treatment results from different centers are essentially comparable in that the crude five‐year survival rates for all glottic and for all supraglottic cases were not strongly correlated with the type of primary therapy used. There has been no improvement in crude or actuarial survival rates in the period under review (1955–1971). No statement as to quality of survival is possible at the present time, but it is hoped that subsequent information will shed some light on this topic.
