Clinical Analysis of Laryngeal Spindle Cell Carcinoma

Abstract

<b><i>Aims:</i></b> To investigate the clinical features, treatment, and outcomes of laryngeal spindle cell carcinoma (SpCC). <b><i>Methods:</i></b> Between 2005 and 2014, patients from our hospital with SpCC of the larynx were retrospectively analyzed alongside patient data from the SEER database of America. <b><i>Results:</i></b> A total of 11 patients with SpCC of the larynx were diagnosed and underwent surgery in our hospital. All patients were male and all tumors were located in the glottis. The 3- and 5-year OS rates were both 54.5%. In the SEER database, 148 patients were diagnosed with SpCC of the larynx. The 3- and 5-year OS rates were 72.8 and 63.2%, respectively. According to the comparison of propensity score-matched analysis, the OS was longer in squamous cell carcinoma (SCC) of the larynx (<i>p</i> &#x3c; 0.0001). <b><i>Conclusion:</i></b> SpCC of the larynx is rare and typically originates in the glottis. Its prognosis is worse than that of laryngeal SCC, and surgery is a reasonable treatment strategy.
