Kaplan-Meier analysis revealed no significant association of SATB1 expression with OCSS or OS in the full cohort (data not shown) but stratified analysis according to tumour grade revealed that positive SATB1 expression was a significant factor of poor prognosis in high grade tumours (n = 105), regardless of histological subtype (logrank p = 0.004 for OCSS and logrank p = 0.015 for 5-year OS, (Figure3 A-B). The gene discussed is SATB1; the disease is neoplasm.
