Lymphnode metastasis in head and neck squamous cells carcinoma: multivariate analysis of prognostic variables

J Exp Clin Cancer Res. 1999 Mar;18(1):79-83.


Cervical lymphnodes metastatization by the squamous cell carcinoma of the head and neck is well known as a prognostic negative factor as far as survival is concerned. Multivariate analysis has been used on 207 cases of head and neck squamous cell carcinomas (HNSCC) in order to identify the possible prognostic significance of a group of clinical and histopathological characteristics, aiming to find a correlation with the possible occurrence of cervical lymphnodes. Two hundred and seven patients (168 males and 39 females, mean age: 62 years) with SCCHN were studied. They underwent surgery alone and radiotherapeutic associated treatment. Variables regarding the patient, carcinoma and histology were analysed: age, sex, smoking and alcohol consumption, performance status, concomitant internal pathologies (cardiopathies, hepatopathies, broncho-pneumopathies, metabolic disorders), site and size of primary tumor (T stage), number and size of laterocervical lymph node localization (clinical N stage), grading, vascular permeation, perineural infiltration. Multivariate analysis of prognostic factors was performed using BMDP's PLR programme. Some variables showed a great risk of lymphnode metastasis; among sites: supraglottic larynx (p = 0.05), base of the tongue (p = 0.04), hypopharynx (p = 0.05); some histological parameters as lower degree of histological differentiation (p = 0.02), the presence of vascular permeation (p = 0.06) and perineural invasion (p = 0.07) appear to represent predisposing factors for the onset of adenopathies. By considering prognostic factors as shown, it is possible to better identify metastasis risk cases, that leads to improved therapeutical strategies.
