Aims: To assess the functional outcomes of patients treated for hypopharynx cancer and to obtain an unbiased estimate of survival difference between patients treated with chemoradiotherapy (CRT) or total laryngectomy (TL). Methods: Retrospective cohort study of all patients treated with curative intent for T1-T4 squamous cell carcinoma of the hypopharynx in The Netherlands Cancer Institute (1990–2013). Functional outcome following radiotherapy (RT) or CRT was measured using laryngo-esophageal dysfunction free survival rate (LDFS). Using propensity score (PS) matched analysis, we compared survival outcome of TL to CRT in T2-T4 patients. Results: We included 343 patients with T1T4 hypopharynx cancer. LDFS 2 and 5-years following CRT was respectively 44 and 32%. Following RT this was 39 and 30%. Patients were matched on the following variables: age, gender, TNM classification, subsite of tumor, decade of diagnosis, prior cancer, smoking, ACE27 score, BMI hemoglobin, albumin, and leukocyte level. With PS matching, we were able to match 26 TL patients with 26 CRT patients. The OS rates for TL and CRT in this matched cohort were respectively 56% and 46% at 5 years and 35% and 17% at 10 years. Conclusion: In conclusion, functional outcomes following RT or CRT are suboptimal and require improved treatment strategies or rehabilitation efforts. The OS results challenge the preposition that CRT and TLE are equivalent in terms of survival.
