Liver Metastasis in a Gastric Cancer Patient--A Case of Successful Radiofrequency Ablation Combined with Degradable Starch Microspheres Transcatheter Arterial Chemoembolization
Abstract
A 60-year-old male patient underwent curative surgical resection for gastric cancer. After the surgery, the patient was diagnosed with T4b, N3b, ly3, v2, CY0, fStageⅢc gastric cancer, and adjuvant systemic chemotherapy using S-1 and CDDP was administered. However, follow-up computed tomography (CT) scan examination taken 2 months after surgery revealed a pancreatic fistula and retroperitoneal abscess, and percutaneous drainage was performed. After 1 month, the enhanced CT scan detected liver metastasis measuring 25 mm in diameter at segment 7. The CT-guided percutaneous radiofrequency ablation (RFA) combined with transcatheter arterial chemoembolization (TACE) procedure was performed on the liver metastasis using degradable starch microspheres (DSM). Two months after the RFA, a follow-up CT scan revealed local recurrence of the lesion in the medial side of the ablated area in segment 7. A second CT-guided RFA, which was combined with DSM-TACE, was performed on the recurrent lesion. The patient has since survived more than 2 years after the second treatment without any further recurrences. This case report suggests that RFA treatment combined with DSM-TACE might be a safe and feasible treatment for liver metastasis from gastric cancer.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
