title: [The value of cervical lymph node ultrasound examination in patients suffering from laryngeal cancer].
abstract: 51 patients with laryngeal cancer were surgically treated on the ENT Departament of the St Lukas District Hospital in Tarnow between the years 1997-2000. The local advancement was stated as T3 and T4 according to the TNM system. The high grade of tumour differentiation (G1) was established in 13 patients (25.5%), mediam (G2) in 22 (43.1%), and low grade (G3) in 16 patients (31.4%). According to USG examination lymph nodes were estimated as NO in 20 patients (39.2%), as N1 in 21 (41.2%), and as N2 in 10 patients (19.6%). 76 radical and modified radical neck dissections were performed. The presence of lymph node metastases was found in 27 patients (52.9%), in 4 cases there were occult metastases (20% of NO lymph nodes). High rate of metastases was correlated with low (75%) and mediam (54.5%) tumour differentiation grade, and with supraglottic tumour localisation in the larynx (58.6%). 3-year disease-free survival rate was estimated as 58.8%. Poor results of treatment were observed in patients with low grade of tumour differentiation (G3).
