In this study, tumors of histological types carcinosarcoma, anaplastic carcinoma and solid carcinoma (p = 0.002), larger size (p = 0.011), presence of tumor necrosis (p = 0.002), neoplastic intravascular emboli (p < 0.001), lymph node metastasis (p < 0.001), high HGM (p < 0.001) and higher levels of CD31 (p = 0.001), VEGF (p = 0.02) and FoxP3 (p < 0.001), were associated with lower OS time. Here, PECAM1 is linked to neoplasm.
