Institutional review board statement: This study was reviewed and approved by the Ethics Committee of the National Hospital Organization Kyushu Cancer Center (Approval No.2017-16).
Informed consent statement: Patients were not required to give informed consent to the study because the analysis used anonymous clinical data that were obtained after each patient agreed to participate in clinical research by written consent. For full disclosure, the details of the study are published on the home page of National Hospital Organization Kyushu Cancer Center and patients are asked to inform us if they disagree with the use of the clinical data.
Conflict-of-interest statement: This work was partly supported by funding from Eisai (Grant No. HHCS20181030011) (Tokyo, Japan); however, that did not result in potential conflicts for this study because it was designed and performed independently of this funding agency.

Core Tip

Core Tip: Hepatitis B virus (HBV) reactivation in patients during cancer treatment is a critical issue. We retrospectively reviewed the expression of HBV DNA in 1040 patients undergoing anticancer treatment for various types of solid tumors at our institution and examined the patient and disease information. Among the 1040 patients, 938 had both hepatitis B core antibodies (HBcAbs) and hepatitis B surface antibodies (HBsAbs), while 102 had only HBsAbs. We confirmed HBV DNA expression in 44 patients (4.7%, 44/938), all of whom were HBcAb–positive patients. HBV DNA expression was detected before treatment in 9 patients and after treatment in 35 patients. A comparison of the treatments in patients with reactivation and those in patients without reactivation revealed no differences in treatment between groups. However, multivariate analysis identified both a high HBcAb titer and cancers in organs involved in digestion and absorption (such as the oral cavity, esophagus, stomach, colon, and others) as independent factors that contributed to HBV reactivation. Our findings may help identify a subset of cancer patients undergoing treatment that should be monitored for HBV reactivation.
