Abstract

To assess the risk factor of capsular rupture for individual prognosis and potential therapeutic decision making, the present meta-analysis elaborated the prognostic significance of perinodal spread in a large group of patients suffering from head and neck squamous cell carcinomas (HNSCC). A review of the published literature was conducted, and fixed and random effects models were applied for estimation of the summarised odds ratio and 95% confidence intervals, including a test for homogeneity of the odds ratios. Study methodology allowed the enrollment of only nine studies of 115 published papers. Excluded studies lacked regarding primary tumour location, number and location of lymph node metastases, values on five-year survival, or adequate follow-up data. A summarised odds ratio of 2.7 leads to the conclusion that perinodal spread negatively impacts the five-year survival. The lower confidence limit of more than 2 also supports the concept that perinodal spread significantly reduces (doubled risk) the five-year-survival. These results support the conclusion that perinodal spread is a significant adverse risk factor for survival in patients with HNSCC.
