Extracapsular Spread and Desmoplastic Pattern in Neck Lymph Nodes: Two Prognostic Factors of Laryngeal Cancer

Abstract

The influence of extracapsular spread (ECS) and a desmoplastic pattern (DP) of metastatic cervical lymph nodes in patients with laryngeal cancer is presented. The study includes 128 patients surgically treated between 1984 and 1992 for squamous cell carcinoma of the larynx with pathologically proven lymph node metastasis. The results were studied from 2 major standpoints: survival and recurrence. The 3-year survival rates were as follows: patients without ECS 73.4%, and with ECS 28.9% (p < .001); patients without a DP 76.9%, and with a DP 43.3% (p < .03). Also, the 3-year recurrence rates in the neck showed significant differences: patients without ECS 10.7%, and with ECS 49.6% (p < .001); patients without a DP 10%, and with a DP 31.6% (p = .1142). Postoperative radiotherapy did not appear to improve the outcome.
