Background:
We reviewed the outcomes of patients with T3 laryngeal neoplasms with a fixed hemilarynx, a large gross tumor volume or a subglottic extension (SGE), treated with a laryngeal-preservation protocol with induction chemotherapy.
Patients And Methods:
The study end-points were laryngo-esophageal dysfunction-free survival (LEDFS), laryngectomy-free survival (LFS), overall survival (OS), and disease-free survival (DFS).
Results:
A total of 104 patients were included. The 2-year and 5-year OS rates were 70.4% and 54.5%, respectively. OS and DFS were independent of the treatment modality in the whole cohort (p=0.6546 and p=0.3006, respectively) and in patients with SGE (p=0.529 and p=0.255, respectively). The 2-year and 5-year LEDFS rates were 44.3% and 28.2%, respectively. LEDFS was not associated with initial hemilaryngeal fixation or SGE (p=0.5772 and p=0.0623, respectively).
Conclusion:
Chemoselection is feasible without compromised oncological or functional outcomes in patients with an initially fixed hemilarynx or subglottic extension.

Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals....
