Possibly important characteristics included in the multivariate analysis after being individually tested for correlation with OS were age (p = 0.056), lymph node status (p = 0.042), simplified peritoneal cancer index (PCI) [39] (p = 0.052), resection outcome (p = 0.021), preoperative chemotherapy 6 months before HIPEC (p = 0.007), VEGF (p = 0.035) and epithelial VCAN (p = 0.109) (Table 3). This evidence concerns the gene VEGFA and peritoneum cancer.
