Long-Term Survival of Patients After Total Pharyngolaryngoesophagectomy With Gastric Pull-Up Reconstruction for Hypopharyngeal or Laryngeal Cancer Invading Cervical Esophagus

Objectives: Hypopharyngeal and laryngeal cancers are aggressive and usually diagnosed at advanced stage with esophagus invasion. Total pharyngolaryngoesophagectomy with gastric pull-up reconstruction has been a common surgery for these cancers but long-term outcomes are still questionable. This study aimed to investigate short-term and long-term outcomes of patients who underwent this surgery. Methods: Patients with hypopharyngeal or laryngeal cancer invading cervical esophagus who underwent total pharyngolaryngoesphagectomy with gastric pull-up between 2012 and 2016 was included and followed up until 2021. Short-term outcomes were complications and long-term outcomes were overall survival (OS) and disease-free survival (DFS). Results: Fifty patients were included with a mean age of 60.3 years and 94% were male. Pyriform fossa was the most common primary site of tumor (50%), followed by posterior hypopharyngeal wall (18%) and postcricoid region (18%). Mean operating time, postoperative oral intake and hospital stay was 363.1 +/- 43.6 minutes, 8.8 +/- 3.6 days and 14.2 +/- 3.0 days respectively. Complications occurred in 15 patients (30%) without any in-hospital death. During the follow-up period, 17 patients had recurrence and 35 patients died. Median (95% confidence interval [CI]) OS and DFS time were 30 (21-37) and 30 (19-36) months. Five-year OS and DFS probability (95% CI) were 22.6% (12.8-39.7) and 22.7% (12.9-39.8). Conclusions: Total pharyngolaryngoesophagectomy with gastric pull-up is feasible and safe. However, even with curative surgery and multimodal treatment, advanced pharyngeal or laryngeal cancer with cervical esophagus invasion still has poor survival outcome.
