OBJECTIVES: We sought to better characterize spindle cell carcinoma (SpCC) of the upper aerodigestive tract, a rare and aggressive variant, through comparison of a large cohort of head and neck SpCCs against a cohort of conventional head and neck squamous cell carcinoma (SCC) patients. METHODS: We compared epidemiologic and clinicopathologic characteristics of 341 SpCCs with 67 882 SCCs of the head and neck, drawing data from the SEER national database. We also compared disease-specific survivals (DSS) for SpCC and SCC based on tumor site and mode of treatment. RESULTS: SpCCs were predominantly laryngeal (46.4%, P < .001) and were more likely to be high grade (P > .001). SpCCs were also more likely than SCCs to present at an early stage (P < .001 to P < .05). Rates of distant metastasis were similar between the tumor types. DSS was similar between SpCCs and SCCs, although site-specific survival rates were higher for SpCCs of the larynx (P = .017) and lower for those of the oral cavity (P = .008). CONCLUSION: SpCC of the head and neck is more likely than SCC to present at an early stage, with fewer nodal metastases. Survival rates appear to depend on anatomic site as well.
