ABSTRACT
Purpose:
Previous studies on the effect of hepatitis B virus (HBV) infection on colorectal liver metastasis (CRLM) are contradictory. This study revealed different, more specific impacts of HBV on CRLM. Patients andMethods:
A total of 3132 colorectal cancer patients treated from 2013 to 2015 were analyzed retrospectively and followed up for five years. The patients were divided into three groups group A (chronic HBV infection, CHB); group B, (occult HBV infection, OHB) and group C (no HBV infection, NHB). The risk factors for CRLM, 5-year overall survival (OS), and liver disease-free survival (LDFS) were analyzed.Results:
A total of 905 patients (28.9%) had CRLM, with poor survival compared to those without CRLM (P < 0.01). The incidence of CRLM was 33.41% (138/413) in group A, 21.63% (138/638) in group B and 30.23% (629/2081) in group C (P < 0.05). Synchronous colorectal cancer liver metastasis (SYN-CRLM) was found in 425 patients (13.57%). CHB increased the risk of SYN-CRLM (P < 0.01), with a worse prognosis (P < 0.05). Metachronous colorectal cancer liver metastasis (MET-CRLM) was found in 480 patients (15.33%). OHB decreased the risk of MET-CRLM after surgery (P = 0.02), with a better 5-year LDFS (P = 0.01). Even without surgery, patients with OHB showed a lower incidence rate of MET-CRLM (P < 0.01).Conclusion:
The incidence of CRLM in this study was approximately 28.9%. Surgery and different HBV infection statuses affected the occurrence of CRLM. Chronic HBV infection increased the risk of SYN-CRLM with poor prognosis. Occult HBV infection reduced the risk of MET-CRLM with better LDFS after surgery.
