Changes in circulating EBV DNA with pembrolizumab treatment. The EBV DNA levels in case 2 fell from 1330 copies/ml to < 500 copies/ml after 5 cycles. The EBV DNA levels in case 3 fell from 1390 copies/ml to < 500 copies/ml after 3 cycles. The EBV DNA levels in case 5 rose from normality to 2140 copies/ml after 2 cycles and went back to normal 4 cycles later. The EBV DNA levels of case 6 rose from 22,100 copies/ml to 224,000 copies/ml after 3 cycles. The EBV DNA levels of case 7 rose gradually from 10,900 copies/ml to 190,000 copies/ml prior to pembrolizumab treatment
