Organ preservation and oncological outcomes in early laryngeal cancer: a propensity score-based study

BACKGROUND: The rates of laryngeal preservation according to therapeutic modality in patients with initial laryngeal squamous cell carcinoma (LSCC) are still controversial. This study evaluated the rates of laryngeal preservation in patients who underwent treatment with surgery or radiotherapy. METHODS: This retrospective cohort study evaluated 151 patients with stage I or II LSCC. Ninety-six patients were matched using a propensity-score and outcomes were compared within this group. RESULTS: Regarding overall, cancer-specific survival and larynx preservation, no differences were observed according to the therapeutic modalities, but patients who underwent radiotherapy had a higher rate of local recurrence than those who underwent surgery. Patients classified as ASA 3 or 4 and treated with radiotherapy showed a tendency of higher risk of larynx loss. CONCLUSIONS: Patients with stage I or II laryngeal tumours can be submitted to surgery or radiotherapy with similar rates of laryngeal preservation.
