Background:
Although already established for treatment for early-stage laryngeal cancers, transoral laser microsurgery indications for more advanced tumors are not unanimous. Additionally, no outcomes concerning the Portuguese population are currently accessible.
Methods:
Outcomes of 248 patients presenting laryngeal carcinoma primarily treated by transoral laser microsurgery with curative intention in tertiary referral center were retrospectively evaluated and compared with concerning literature.
Results:
For supraglottic tumors (23 stage I-II and 20 stage III-IV), 5-year disease-specific survival (DSS) was, respectively, 88.4% and 72.7%, and the total larynx-preservation rate was 90.7%. For glottic cancer (165 stage I-II and 40 stage III-IV), 5-year DSS was, respectively, 96.5% and 90.8% and the larynx preservation rate was 88.3%.
Conclusion:
Transoral laser microsurgery, alone or with neck dissection and adjuvant therapy, is an efficient procedure for treatment of laryngeal cancer in different stages. To the best of our knowledge, this is the first study reporting transoral laser microsurgery outcomes in the Portuguese population.
