Plasma levels of Hsp90α in patients with different stages of liver cancers and Hsp90α ROC curve of auxiliary diagnosis of liver cancer. a shows plasma Hsp90α levels in liver cancer patients with TNM I–IV .Compare the plasma Hsp90α levels of patients in each stage, I and II (P = 0.005), III and IV (P = 0.046), showed significant differences, II and III (P = 0.831) showed no significant differences in plasma Hsp90α levels. b shows ROC curve of plasma Hsp90α for I–IV liver cancer patients versus non-liver cancer group. c shows ROC curve of plasma Hsp90α for I–II liver cancer patients versus non-liver cancer group. Hsp90α, plasma heat shock protein 90 alpha; LC, liver cancer; ROC, receiver operating characteristic; AUC, area under curve
