OBJECTIVE: Larynx preservation is the current standard for locally advanced (LA) laryngeal/hypopharyngeal tumors, but not all patients respond as expected. TALK score model measures four variables (T-staging, albumin levels, liquor consumption and Karnofsky score) to determine which cases are best suited to preservation treatment scheme. We aimed to validate this prognostic model in a Southern European population.
METHODS: We retrospectively evaluated 175 patients diagnosed from July 2008 to December 2015 with LA laryngeal/hypopharyngeal carcinoma and treated with a laryngeal preservation scheme comprising induction chemotherapy followed by concomitant chemotherapy and radiotherapy. We applied the TALK score model to predict larynx preservation rate.
RESULTS: Of the 175 patients evaluated, 96.6% were men, 98.3% were smokers and 77.1% misused alcohol. Tumors were laryngeal 66.3% vs 33.7% in hypopharynx, and all were either stage III (37.7%) or stage IV (62.3%). TALK prognostic subgroups were: good risk 40.0%; intermediate risk 52.5%; and poor risk 7.5%. With a median follow-up of 40.1 months, larynx preservation rate, laryngectomy-free survival and overall survival at 3 years was 84.5%, 63.7% and 68.2%, respectively. Although TALK score was not predictive of 3-year larynx preservation rate (good risk 85.5%; intermediate risk 83.1%; poor risk 91.6%), it was predictive of 3-year overall survival (good risk 81.9%; intermediate risk 62.9%; poor risk 33.5%) and 3-year laryngectomy-free survival (good risk 75.6%; intermediate risk 59.6%; poor risk 30.7%).
CONCLUSION: TALK model could predict OS and laryngectomy-free survival, helping clinicians to decide which patients should avoid laryngeal preservation and undergo laryngectomy after diagnosis.
