Regional and distant metastases in laryngeal and hypopharyngeal sarcomas.
Cervical node and distant metastases are the most important prognostic factors in malignant laryngeal neoplasms. Owing to the unusual occurrence of laryngeal sarcomas, the prevalence of their metastases has never been analyzed in detail. We reviewed the laryngeal sarcomas reported in the literature and noticed that both regional and distant metastases are rare events and variable for different histotypes. These observations have obvious therapeutic and prognostic implications.
