PTPRD expression and its significance in gastric cancer. a Representative photomicrographs of immunostaining for PTPRD in normal gastric mucosa and gastric cancer (GC) tissues. b The levels of PTPRD expression in GCs. c Correlations between PTPRD expression and T or N stages. d-e Overall survival (d) and tumor recurrence (e) after surgery were analyzed according to PTPRD expression, using a Kaplan-Meier estimator. The number of patients at risk is indicated. f Comparison of recurrence rates according to PTPRD expression at the local region, lymph nodes, and distant sites. Distant sites include other organs, such as the peritoneum, liver, and lungs. Scale bar = 50 μm
