Effect of storage time of paraffin sections on the expression of PD-L1 (SP142) in invasive breast cancer

Abstract Background PD-L1 staining using long-stored paraffin sections may not be consistent with the true PD-L1 expression of patients. Therefore, it is necessary to explore the expression of PD-L1(SP142) in paraffin sections of invasive breast cancer with different storage times and the optimal st...
