Limited data exists on the non-surgical management of stage T4 larynx and hypopharynx cancer patients who are not surgical candidates or refuse surgery. This study aims to investigate the clinical and functional outcomes of non-surgical management of T4 larynx and hypopharynx cancer patients. The outcomes reported in this study will provide guidance for those who have unresectable disease or refuse surgery for advanced laryngeal and hypopharyngeal cancer patients.
Objective
Limited data is available to guide non-surgical management of Stage T4 larynx and hypopharynx cancer patients who have inoperable disease or refuse surgery. We aim to review the nonoperative management of T4 laryngeal and hypopharyngeal cancer and report the long-term therapeutic and functional outcomes.
Methods
We reviewed the nonoperative management of T4 laryngeal (n = 44) and hypopharyngeal (n = 53) cancer from 1997 to 2015 and performed a univariate analysis (UVA).
Results
The 2-/5-year OS rates were 73%/38% for larynx patients and 52%/29% for hypopharynx patients. Locoregional failure (LRF) occurred in 25% and 19% of larynx and hypopharynx patients, respectively. On UVA of the larynx subset, N3 nodal status and non-intensity-modulated radiation therapy were negatively associated with OS; treatment with radiation therapy alone impacted disease-free survival; and age >70 was associated with LRF. On UVA of the hypopharynx subset, only T4b status significantly impacted OS. In the larynx and hypopharynx groups, 68% and 85% received a percutaneous endoscopic gastrostomy (PEG) tube and 32% and 40% received a tracheostomy tube, respectively. At the last follow-up visit, 66% of our larynx cohort had neither tracheostomy or PEG placed and 40% of our hypopharynx cohort had neither.
Conclusion
We report better than previously noted outcomes among T4 larynx and hypopharynx patients who have unresectable disease or refuse surgery.
