Additionally, the high expression of RCC1 is also related to poor OS, relapse-free survival (RFS), distant metastasis-free survival (DMFS) and PPS in breast cancer and poor OS, RFS, disease-specific survival (DSS) and progress-free survival (PFS) in liver cancer (Supplementary Figure S5e,f, all p < 0.05). The gene discussed is RCC1; the disease is liver cancer.
