The results showed that low PCK1 expression was an independent factor predicting worse DFS, and tumors with low PCK1 expression were associated with a 2.23-fold increase in the risk of cancer recurrence or metastasis (hazard ratio = 2.23, 95% confidence interval [1.02–4.89], P = 0.033) (Table 2). Here, PCK1 is linked to cancer.
