Patients with squamous-cell carcinoma of the head and neck who received docetaxel plus cisplatin and fluorouracil induction chemotherapy plus chemoradiotherapy had a significantly longer survival than did patients who received cisplatin and fluorouracil induction chemotherapy plus chemoradiotherapy.

Background NUT midline carcinoma (NMC) is a rare and aggressive genetically characterized subtype of squamous cell carcinoma frequently arising from the head and neck (HN). HNNMC characteristics and optimal management are unclear. Methods We performed a retrospective review of all known cases of HNNMC in the International NMC Registry, data as of December 31, 2014. Of 48 consecutive patients treated from 1993–2014, clinicopathologic variables and outcomes from 40 patients were available for analyses, the largest cohort of HN NMC studied to date. Overall survival (OS) and progression-free survival (PFS) according to patient characteristics and treatment were analyzed. Results We identified a five-fold increase in diagnosis of HNNMC from 2011 to 2014. Median age was 21.9 years (range 0.1–81.7), male:female was 40%:60%, and 86% had BRD4-NUT fusion. Initial treatment was initial surgery (S) +/− adjuvant chemoradiation (CRT) or adjuvant radiation (RT) (56%), initial RT +/− chemotherapy (C) (15%), or initial C +/− S or RT (28%). Median PFS was 6.6 months (range 4.7–8.4). Median OS was 9.7 months (range 6.6–15.6). Two-year PFS was 26% (95% CI, 13%–40%). Two-year OS was 30% (95% CI, 16%–46%). Initial S +/− post-operative CRT or RT (p=0.04), and complete resection with negative margins (p=0.01) were significant predictors of improved OS even after adjustment for age, tumor size and neck lymphadenopathy. Initial RT or C, and NUT translocation type were not associated with outcome. Conclusions HNNMC portends a poor prognosis. Aggressive initial surgical resection +/− post-operative CRT or RT was associated with significantly enhanced survival. C or RT alone is often inadequate.
