Abstract

The purpose of this study was to investigate the clinical usefulness of microvessel density (MVD) and an in vivo angiogenesis parameter, color Doppler vascularity index (CDVI), in patients with gastric cancer. Many studies have reported a significant association between the degree of MVD-evaluated angiogenesis with the clinicopathologic factors and prognosis of patients with various solid tumors. All these studies were accomplished on tissue sections retrospectively obtained from surgical specimens. However, an in vivo method to assess tumor angiogenesis for human malignancies is highly desirable for diagnostic purpose, treatment planning, and follow-up. The CDVI is a new ultrasound parameter for evaluating in vivo angiogenesis, has a good correlation with status of lymph node metastasis in cervical carcinoma, and can predict distant metastasis and survival in colon cancer patients. Therefore, the CDVI may also be useful to assess in vivo angiogenesis in human gastric cancer. A total of 79 patients with gastric cancer were enrolled in this study, and microvessel density was evaluated by using immunohistochemical staining of surgical specimens with anti-CD-34 antibody. Tumors were sonographically visible in 31 patients. The CDVI...Continue Reading
