A Case of Long-Term Survival of a Patient with Gastric Cancer with Synchronous Liver Metastasis and Portal Vein Thrombus after Multidisciplinary Treatment
Abstract
A 77-year-old man was diagnosed with gastric cancer with synchronous single liver metastasis and portal vein thrombus. His HER2 immunohistochemistry tumor score was 3+; therefore, we administered trastuzumab plus capecitabine plus cisplatin. After 2 courses of chemotherapy, we observed disappearance of the portal vein thrombus and tumor reduction as a partial response, according to the RECIST guidelines. We performed distal gastrectomy and right lobectomy; the therapeutic grades of the primary and metastatic tumors were 1a and 2, respectively. We administered postoperative chemotherapy, and no recurrent lesions have appeared 2 years after surgery. Multidisciplinary treatment for gastric cancer with liver metastasis might be a feasible and useful strategy.
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.
