title: Resection of hepatocellular carcinoma with tumor thrombus of the portal vein after neoadjuvant regional chemotherapy.
abstract: We report a successfully managed case of far-advanced hepatocellular carcinoma (HCC) by intraarterial infusion therapy. A 55-year-old man was admitted to our hospital with abdominal pain and subileus. Abdominal ultrasonography, computed tomography, and angiography revealed HCC with obstruction of the main portal vein due to tumor thrombus. Serum levels of alpha-fetoprotein (AFP) and protein induced by vitamin K absence or antagonist-II (PIVKA-II) were elevated. Neoadjuvant chemotherapy was tried with a course of low-dose cisplatin (CDDP) +5-fluorouracil (5-FU) intrahepatic arterial infusion through the indwelling catheter via the subcutaneous reservoir port. After 7 weeks of administration (total dose CDDP 370 mg/5-FU 18.5 mg), the main tumor size was effectively reduced. Serum levels of AFP and PIVKA-II decreased markedly. Adverse effects were tolerated. Following the chemoinfusion therapy, posterior segmentectomy and thrombectomy were performed. Reconstruction of the portal vein was not necessary because we removed the tumor thrombus without resecting the portal vein. The postoperative course was uneventful, and the patient has been doing well more than 2 years after surgery, with no evidence of recurrence or metastasis. Preoperative low-dose CDDP +5-FU intrahepatic arterial infusion therapy in combination with hepatic resection may be an effective treatment for advanced HCC with portal vein tumor thrombus.
