“…4,8 Not unexpectedly, OS was affected, on univariate analysis, by pT status, pN status, PNS, facial nerve palsy, and pain at presentation, thus confirming the results of previous studies in which high pT category (pT3-4), nodal involvement, and PNS were the factors associated with dismal prognosis. 4,9,14,18,19,22,25 The same factors also clearly impacted DSS (5-year DSS, 76.6%; 10-year DSS, 72.1%) and RFS (5-year RFS: 69.1%; 10-year RFS: 62.4%), both in line with previously reported values (5-year DSS: 61%-76%, 5-year RFS: 57%). 4,8,20 This is further reinforced by our multivariate analysis, underlining the independent impact of PNS and nodal involvement on most survival and recurrence outcomes (Figs.…”
