To explore the effects of integrin αvβ3/α6β1 on the prognosis of PCa patients, we performed Kaplan-Meier analysis for overall survival (OS), relapse-free survival (RFS) and biochemical recurrence based on the expression levels of integrin ITGAV, ITGA6, ITGB1 and ITGB3 in these samples. The gene discussed is ITGB1; the disease is posterior cortical atrophy.
