Popis: Hypopharyngeal cancer (HC) is an aggressive and life-threatening malignancy that requires a complex multimodal treatment. The aims of the present study were to analyze, in locally advanced HC patients, the oncologic and swallowing outcomes and their predictive factors according to the therapeutic strategy.All patients with locally advanced HC (T3/T4, N0-3, M0) treated at our institution between 2000 and 2020 were included in this retrospective study. Patients were classified in 3 groups according to the therapeutic strategy: primary radical surgery (RS), induction chemotherapy (ICT) or definitive (chemo)-radiation therapy ((C)RT). Predictive factors of oncologic outcomes (overall, cause-specific and recurrence-free survival: OS, CSS and RFS) and swallowing outcome (dysphagia outcome and severity scale: DOSS) were investigated in univariate and multivariate analysis.A total of 217 patients were included in this study (RS: 40; ICT: 106; (C)RT: 71). 5-year OS, CSS and RFS rates were 36, 38 and 32%, respectively. ICT was associated with improved oncologic and swallowing outcomes in univariate analysis. After multivariate analysis, patient age ≥ 70 years (p = 0.0002) was the only factor significantly associated with a worse OS, whereas patient age ≥ 70 years (p = 0.002) and N stage ≥ 2 (p = 0.01) were significantly associated with a worse CSS. Comorbidity level (KFI ≥ 2; p = 0.01) and N stage (≥ 2; p = 0.02) were significantly associated with worse swallowing outcomes.In selected locally advanced HC patients, an ICT-based therapeutic strategy offers acceptable oncologic and functional outcomes. Patient age, N stage and comorbidity level are the main determinants of oncologic and functional outcomes.
