(a) The change in HCV-RNA in cases with treatment resistance or recurrence. (b) The change in HCV-RNA in cases that maintained remission. In many cases that showed treatment resistance or recurrence, HCV-RNA levels transiently increased after the third anti-cancer treatment compared to pretreatment levels. Although in two cases HCV-RNA level decreased compared to pre-treatment level, values were higher than the pre-treatment level after the sixth treatment. In contrast, in some of the cases that maintained remission, HCV-RNA levels increased transiently after the third treatment, but after the sixth treatment decreased to lower than pre-treatment levels.
