Abstract
Epidermal-growth-factor-receptor (EGFR) expression was evaluated in 103 primary laryngeal tumors and in 42 normal laryngeal tissue specimens. Significantly higher EGFR levels were found in cancer specimens than in normal mucosa (p = 0.0053). EGFR expression did not correlate with age, tumor localization, T classification, cervical-lymph-node involvement or type of surgery, whereas it was higher in poorly differentiated tumors (G3) than in well/moderately differentiated (G1-G2) tumors (p < 0.05). Follow-up data were available for 74 patients. When EGFR status and the most important clinico-pathological characteristics were submitted to univariate analysis, tumor localization, type of surgery and EGFR status were found to be significantly correlated with disease-free survival. The 24-month disease-free survival rate was 58% for EGFR+ cancer patients and 82% for EGFR- ones. With multivariate analysis, only EGFR status and tumor localization were identified as significant independent prognostic parameters. Data reported here suggest that high EGFR levels may identify a sub-set of laryngeal-cancer patients with a particularly unfavorable prognosis. © 1992 Wiley-Liss, Inc
