Kaplan-Meier analysis showed that patients with tumors showing low ARID1A expression (IHC score<180) showed a significantly lower rate of tumor recurrence (P = 0.011) but had a higher rate of tumor progression (P = 0.112), further indicating that loss of ARID1A expression is associated with more aggressive tumors (Figure 4). The gene discussed is ARID1A; the disease is neoplasm.
