Moreover, most studies agreed that among treated persons cancer risk was not higher in those receiving DAAs (DAAs only or DAAs + PEG-IFN) compared with those treated with PEG-IFN only (hazard ratio (HR): 1.1) [156,157,158,159,160,161,162,163,164,165,166,167,168,169]. The gene discussed is IFNA1; the disease is cancer.
