Abstract | PURPOSE: METHODS: RESULTS: Of the 95 patients reviewed in the present study, 9 (9.5%), all with adenocarcinoma (Ad), showed positive APN expression on the tumors' cells. In all, 31 (32.6%) and 19 (20.0%) patients showed positive APN expression on the tumors' stromal cells (fibroblasts) and microvessels, respectively. APN expression on the tumors' stromal cells was more frequently observed in squamous cell carcinoma patients than in adenocarcinoma patients (P = 0.005). The mean microvessel density (MVD) for APNpositive tumor stromal cells was 59.9, which was significantly higher than that for APN-negative tumor stromal cells (mean MVD 27.4; P = 0.001). The 5-year survival rates for APN-positive and APN-negative tumor stromal cells were 66.0% and 69.8%, respectively, showing no difference in patient survival according to APN status on the tumors' stromal cells. CONCLUSION:
