Expression of FADD and its phosphorylated isoform (pFADD) have been associated with aggressive tumor growth, lymph node metastasis, and overall survival. Previously, we demonstrated that pFADD expression was related to a significantly improved local control in early stage (tumor [T]1 to T2) glottic laryngeal squamous cell carcinoma (LSCC). The aim of this study was to examine the prognostic value of pFADD and FADD in T1 to T2 supraglottic LSCC treated with primarily radiotherapy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Tumor tissue sections of 60 patients with T1 to T2 supraglottic LSCC treated with primarily radiotherapy were assessed immunohistochemically for expression of pFADD and FADD. Expression percentages and clinical parameters and their associations with clinical outcome were studied using Cox regression and Kaplan\u2010Meier survival analyses.
