Abstract
BACKGROUND: Lymphatic vessel density (LVD) has been shown to be an important predictor of survival in head and neck cancers. We report the predictive value of LVD for progression-free survival (PFS) and overall survival (OS) in laryngeal/hypopharyngeal cancer. METHODS: Fifty-five untreated patients with T3/T4 laryngeal and T4 hypopharyngeal cancer underwent laryngectomy between 1999 and 2010. Surgical specimens were immunostained with D2-40, a specific lymphatic marker. LVDs were determined in tumor vessel "hot spots." Recursive partitioning analysis identified LVD thresholds for both peritumoral (LVDpt) and intratumoral (LVDit) vessels for association with PFS and OS. RESULTS: Patients with mean LVDit of <11 vessels/mm(2) had 2-year PFS and OS rates of 58% and 65%, respectively, compared to 13% and 13% for those with LVDit ≥11 vessels/mm(2) (p = .06 and .04, respectively). CONCLUSION: Intratumoral lymphatic vessel density is predictive of PFS and OS in locally advanced laryngeal/hypopharyngeal cancer.
