Rational choice of induction chemotherapy-based larynx preservation for hypopharyngeal cancer

AbstractBackgroud: Induction chemotherapy, as a larynx preservation treatment, has been available for over 20 years. We conducted a retrospective study to evaluate the efficacy of this protocol with taxene, cisplatin and 5-fluorouracil in Chinese patients with hypopharyngeal cancer that chose preservation strategy.Material and methods: 170 patients with locally advanced hypopharyngeal cancer were assigned to receive induction chemotherapy. 107 patients (63%) with complete response or partial response received larynx preservation treatment and 63 non-responders (37%) received radical surgery.Results: Median survival time was 30 months (range: 3–59 months). 63 patients (37%) had local-regional failure and 15 (9%) had distant metastasis. Three-year LFS was 27.8% (95% CI: 23.6–32.0%). The estimated three-year overall survival rate was 44.5% (95% CI: 39.5–49.5%). There was no significant difference in the three-year survival rate between responders (44.8%) and non-responders (43.9%) (p = .237), however patient...
