Vocal cord paralysis and tumour length in staging postcricoid cancer

Eur J Surg Oncol. 1987 Apr;13(2):131-7.

Abstract

The present UICC classification of postcricoid cancer is based on directions of tumour spread which are uncommon and difficult to assess clinically. The classification takes no note of spread into the cervical oesophagus and fails to correlate staging with survival. The aim of this study was to assess the value of other criteria, including vocal cord paralysis and tumour length, in staging 157 patients with postcricoid cancer. Both vocal cord paralysis and tumour length could be assessed in most patients, and correlated with the mode of treatment. Generalized Linear Interactive Modelling (GLIM) identified vocal cord paralysis (P less than 0.001), performance status (P less than 0.025) and the interaction of length and histological grade (P less than 0.05) as significant predictors of survival. None of these variables is included in the current UICC classification.
