By univariate OS analysis, age (p = 0.004), CRP/Alb (p < 0.001), tumor stage (p < 0.001), postoperative residual tumor mass (p < 0.001), histological subtype (p = 0.015), ascites (p = 0.011), CRP (p = 0.027), hypoalbuminemia (p < 0.001), GPS (p = 0.025), mGPS (p = 0.018), PLR (p = 0.006), PNI (p = 0.003) and PI (p = 0.028), but not histological grade, CA-125 level or NLR, were associated with postoperative OS. The gene discussed is CRP; the disease is Hypoalbuminemia.
