Microwave ablation (MWA) has been proven to be highly effective in treatment of small primary liver cancer. However, the procedure may trigger an inflammatory response and cause liver injury in primary liver cancer patients undergoing MWA. As such, it is needed to find reliable markers to monitor and evaluate patient response to MWA. Previous studies have shown that Golgi protein 73 (GP73) are associated with liver inflammatory injury.
This study was designed to test our hypothesis that serum GP73 levels altered in response to MWA in patients with primary liver cancer, and thereby could be used as a potential marker for MWA-induced liver inflammation and injury.
The main objective of this study was to examine effects of MWA on the serum levels of GP73 before and at different time points after the ablation procedure in patients with primary liver cancer.
Patients with primary liver cancer (≤ 3 cm in diameter) receiving MWA were retrospectively enrolled in this study. Serum GP73 levels were compared before and 1, 2, and 4 wk after the ablation procedure.
The serum GP73 levels were significantly elevated at 1 and 2 wk after MWA with the peak at 2 wk after completion of the treatment. The serum GP73 levels decreased starting at 4 wk after MWA and continued to decline to the pretreatment level at 12 and 24 wk after MWA. It was worthy to note that the alterations of serum GP73 levels in response to MWA were similar to those of liver biochemical indicators.
The findings of this study have demonstrated that serum GP73 levels altered in response to MWA in patients with primary liver cancer, and thereby measurement of serum GP73 level holds potential as a biomarker for monitoring and assessment of MWA-mediated inflammatory injury in patients with primary liver cancer.
Future prospective studies are needed to validate the findings and to assess the diagnostic accuracy of serum GP73 for monitoring liver injury following MWA treatment for primary liver cancer.
