TIMP1 and hepatocellular carcinoma: We constructed Kaplan-Meier survival curves and found that the median overall survival was 23.46 months for HCC patients with elevated tumor tissue TIMP-1 expression (TIMP-1 high group), whereas the median overall survival was 58.17 months for HCC patients with lower TIMP-1 levels in adjacent liver tissues (TIMP-1 low/non group).
