AIMS AND BACKGROUND: The metastatic spread of squamous cell carcinoma of the head and neck (SCCHN) to the cervical lymph nodes is a negative prognostic factor in terms of survival. We have used multivariate analysis to identify the possible prognostic significance of a number of clinical and pathological characteristics in relation to possible involvement of the cervical lymph nodes in a series of 396 patients.
METHOD: 396 patients with SCCHN were studied. Variables regarding the patient, the carcinoma and histology were analysed by multivariate analysis using BMDP's PLR programme.
RESULTS: Some variables appear to represent predisposing factors for tumor spread to the lymph nodes: tumor site (supraglottic larynx: P = 0.005; base of the tongue: P = 0.02; hypopharynx: P = 0.02), grading (P = 0.001), and a number of histological parameters (lower degree of histological differentiation: P = 0.001; vascular permeation: P = 0.04; perineural invasion: P < 0.05; prevalently plasmocytic infiltrate: P < 0.05).
CONCLUSION: The identification of cases at risk for metastasis can be improved by the assessment of prognostic factors, with a consequent improvement in treatment strategies.
