Solid tumor chemotherapy regimens pose a risk for hepatitis B virus (HBV) reactivation, but screening and antiviral prophylaxis remains controversial because of insufficient evidence.
To determine the risk for HBV reactivation with and without antiviral prophylaxis and the effectiveness of prophylaxis in adults with solid tumors and chronic or resolved HBV infection.
MEDLINE through 1 July 2015 and Web of Science, Cochrane Central Register of Controlled Trials, TOXNET, and Scopus through 1 March 2015.
26 English-language observational studies and randomized, controlled trials in patients with chronic or resolved HBV receiving chemotherapy for solid tumors.
Study characteristics, quality, and risk of bias were assessed by 1 researcher and verified by another independent researcher.
Random-effects model meta-analyses were used to estimate the risk and odds ratio (OR) of reactivation with versus without antiviral prophylaxis. Reactivation in chronic HBV without prophylaxis ranged from 4% to 68% (median, 25%) with substantial heterogeneity. Prophylaxis reduced the risk for HBV reactivation (OR, 0.12 [95% CI, 0.06 to 0.22]), HBV-related hepatitis (OR, 0.18 [CI, 0.10 to 0.32]), and chemotherapy interruption (OR, 0.10 [CI, 0.04 to 0.27]). In 3 studies of patients with resolved HBV infection, none received HBV prophylaxis and reactivation risk ranged from 0.3% to 9.0%.
Significant heterogeneity in underlying study populations and treatment regimens, incomplete baseline data, possibility of publication bias, and limited study quality. Most studies were observational and from Asia.
In patients with chronic HBV receiving solid tumor chemotherapy, the risk for HBV reactivation is similar to the risk with other types of immunosuppressive therapy. Results support HBV screening and antiviral prophylaxis before initiation of chemotherapy for solid tumors.
