Abstract
A single metastatic liver tumour from a primary gastric cancer is rare.
Glisson’s pedicle invasion was identified on preoperative MR and PET-CT imaging.
Surgical resection, with R0 margin, was deemed possible based on imaging results.
The patient survived, without cancer recurrence for more than 1 year.
Introduction
Metastatic liver tumors from primary gastric cancer are rarely resected because of the high rate of metastasis and recurrence of gastric cancer, and there is little information regarding the pathological assessment of these tumors. We present a case of a single metastatic liver tumor from gastric cancer with invasion of the interlobular bile duct for which we achieved margin-free resection with good clinical outcomes.
Presentation of case
An 80-year-old patient presented with a tumor in segment V of the liver, with invasion of Glisson’s pedicle confirmed on preoperative magnetic resonance and positron emission tomography imaging. On the basis of the preoperative assessment, we proceeded with partial hepatectomy, with transection of one of the roots of Glisson’s pedicle performed under echography guidance. Pathological examination confirmed gastric cancer as the primary source of the metastatic tumor. R0 resection was achieved, with no evidence of cancer recurrence at one year after surgery.
Discussion
Our experience supports partial hepatectomy with R0 margin tumor resection as an oncologically feasible treatment for metastatic liver tumor arising from primary gastric cancer (in the absence of other metastatic lesions) and shows that a good prognosis can be achieved. Of note, intraoperative echography did not detect tumor invasion of Glisson’s pedicle, which was evident only on preoperative imaging.
Conclusion
This case suggests that magnetic resonance and positron emission tomography imaging findings are important for surgical planning of hepatectomy. Further follow-up data and more cases are needed to completely define the clinical significance of tumor invasion of Glisson’s pedicle.
