Abstract
Specimens of laryngeal squamous cell carcinoma (LSCC) were examined for epidermal growth factor receptor (EGFR) content using a radioreceptor method; 140 untreated consecu- tive patients with primary LSCC undergoing initial surgical resection were followed up for a median of 49 months (range 2–84 months) after surgery. Cox univariate regression analy- sis using EGFR as a continuous variable showed that EGFR levels were directly associated with the risk of lymph node metastasis. A significant relationship between EGFR status and cervical node metastasis was observed. The cutoff value of 20 fmol/mg protein was the best prognostic discriminator. The 5-year metastasis-free survival (MFS) was 66% for pa- tients with EGFR tumors compared with 15% for patients with EGFR tumors. By multivariate analysis, the EGFR status appeared to be a significant independent prognostic factor for MFS. Our results suggest that the assessment of EGFR status at the time of diagnosis may identify a subset of LSCC patients highly susceptible to neck node metastases thus defining therapy accordinglyFile | Dimensione | Formato | |
