Pancreatic acinar cell carcinoma successfully treated with combination of oral TS-1 and intra-arterial cisplatin
Abstract
Pancreatic acinar cell carcinomas are rare, and little is reported on their chemotherapy. We report a 49-year old male patient with pancreatic acinar cell carcinoma and multiple liver metastases, which responded to oral TS-1 and hepatic arterial infusion of cisplatin. The patient underwent a partial hepatectomy, MCT abrasions and excision of the pancreatic tumor. Postoperative pathological studies revealed metastases of acinar cell carcinoma to the liver and lymph nodes; the primary lesion was undetermined. After surgery, the patient was treated with hepatic arterial infusion of cisplatin and oral TS-1. Metastatic tumors completely disappeared, and serum lipase decreased to normal levels. Abdominal CT one year after surgery revealed a pancreatic body tumor, which was surgically removed. Pathological studies showed primary pancreatic acinar cell carcinoma, while previous metastases remained under control. To summarize, TS-1 and cisplatin can be effective treatments for pancreatic acinar cell carcinomas.
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.
