Results
Torres et al[18]Prospective observation studyHematological tumor (n = 50)A hepatitis flare occurred in 10% of HCV-infected cancer patients receiving chemotherapy
Non-HCC solid tumor (n = 50)Definition of HCV-related hepatitis flare: unexplained increase in ALT to 3 times the upper limit of normal and increase in HCV-RNA level of ≥ 1 log10 IU/mL over baseline
Li et al[4]Retrospective observation studyHematological tumor (n = 569); HCC (n = 256); Non-HCC solid tumor (n = 3900)The incidence of severe acute liver injury in HCV-infected hematological cancer patients was higher than that in those with HCC patients and non-HCC solid tumor patients (9.4% vs 1.9 % and 1.1%, respectively). Definition of severe acute liver injury: ALT increased beyond 10 times the upper limit of normal during chemotherapy or 6 months following chemotherapy
Tomizawa et al[28]Retrospective observation studyColorectal cancer (n = 24)The incidence of severe acute exacerbation rate in HCV-infected patients was 8%. Definition of severe acute exacerbation: ALT increased beyond 5 times the upper limit of normal
Hsu et al[22]Retrospective observation studyHematological tumor (n = 104); Solid tumor (n = 204)The incidence of HCV acute exacerbation was 11% (hematological tumor: 23%; solid tumor: 4.4%). Definition of HCV acute exacerbation: 3-fold or greater increase in serum ALT level
