Prognostic Impact of Phosphorylated Discoidin Domain Receptor-1 in Esophageal Cancer

Esophageal squamous cell carcinoma (ESCC) is common in East Asia and also is often deadly. We sought to determine whether measuring the discoidin domain receptor-1 (DDR1)-both total and phosphorylated proteins-could improve our ability to predict recurrence in ESCC.Total DDR1 and phosphorylated DDR1 (pDDR1) were measured using semiquantitative immunohistochemistry in a cohort of 60 patients with ESCC. Association between these...
