[The relationship between lymph node size and metastasis and extracapsular spread in squamous cell carcinoma of the larynx, orohypopharynx, and oral cavity].

Objectives: We examined the relationship between lymph node size and metastasis and extracapsular spread (ECS) in patients who underwent neck dissection for squamous cell carcinoma of the larynx, orohypopharynx, or oral cavity.

Patients And Methods: We retrospectively evaluated a total of 200 neck dissections performed in 128 patients (107 males, 21 females; mean age 56+/-11 years; range 26 to 81 years) with squamous cell carcinoma of the larynx, orohypopharynx, or oral cavity, and having complete clinical and pathologic data. Along with 442 metastatic lymph nodes (139 with ECS), the greatest axial diameter of the biggest benign lymph node obtained from each patient was measured.
