[Two Year Recurrence Free Survival after Resection of Cutaneous Metastasis from Pancreatic Cancer - A Case Report].

The patient was a 73-year-old woman who underwent distalpancreatectomy for pancreas tailcancer (T3, N0, M0, stage III ). Hepatic arterialinfusion(HAI)using high-dose 5-fluorouracil(5-FU)(6,000mg/week)was performed 35 days after curative resection to prevent liver metastases. Although chemotherapy with gemcitabine(GEM)was administered for 2 weeks, the patient was aware of a nodule(1 cm in diameter)on the right lower quadrant of the abdomen. Resection of the cutaneous mass was performed and histological findings revealed metastatic adenocarcinoma from the pancreas cancer. Six courses of chemotherapy with GEM were administered as adjuvant therapy. Two years after the treatment with GEM, neurological symptoms appeared, and computed tomography(CT)and magnetic resonance imaging(MRI)revealed a solitary metastatic thalamus tumor(2 cm in diameter). After stereotactic radiotherapy, the patient was transferred to a different hospitalfor physicaltherapy. Herein, we report on a case of 2 year recurrence free survivalafter the resection of a cutaneous metastasis from pancreatic cancer.

[Efficacy of Combined Therapy(Drainage of the Bile Duct, High-Dose Hepatic Artery Infusion, and Radiation)for Hilar Cholangiocellularcarcinoma with Complete Portal Vein Obstruction].

We reported a case of hilar cholangiocellularcarcinoma with complete obstruction of the portal vein. The patient, who was a 65-year-old woman, suffered from fever and general fatigue as a result of acute cholangitis after insertion of a tube stent into the right bile duct. The main tumor was present on the right side of S1 and spread to both sides of the bile duct. S1 lobe was swollen and diffuse intrahepatic invasion was noted in the right lobe and S1. The portal vein was completely obstructed at the porta hepatis with a coronary vein-left renal vein shunt. We immediately administered a high-dose hepatic arterialinfusion( 5-FU 1 g×3 days: one day off 1 g×3 days)(HDHAI)to the right hepatic artery using a transient catheter insertion method. After 2 courses of HDHAI, the intrahepatic invasion decreased. However, after 4 courses of HDHAI(2 on the right side and 2 on the left side), the invasion on the left side of the IVC had increased. We then chose radiation therapy. Subsequently, transient cystic changes were observed; however, 4 months after radiation, the invasion on the left side of the IVC had regrown into the cardia. The patient suffered from vomiting as a result of the narrowing of the esophagus. We chose HDHAI and dilation of the esophagus using a balloon. Finally, the invasion on the left side of the IVC and S1 swelling decreased, and she could eat again. Thirteen months later, she remains an outpatient. We recommend HDHAI and radiation therapy to hilar cholangiocellularcarcinoma even if the portal vein is completely obstructed.

[Pre-Operative Treatment with Transcatheter Arterial Chemoembolization (TACE) and Hepatic Arterial Infusion (HAI) for Liver Metastasis from Gastric Cancer--A Case Report].

The patient was an 83-year-old man who underwent distal gastrectomy for gastric cancer (T3, N1, M0, P0, M0, stage ⅡB) at a different hospital from ours. A metastatic lesion was detected in the liver 5 months after gastrectomy. Although chemotherapy with S-1 or bi-weekly CPT-11 was administered for 6 months, the liver tumor increased in size. The patient was referred to our hospital for treatment of the liver metastasis. Abdominal-computed tomography (CT) and magnetic resonance imaging (MRI) revealed a solitary metastatic liver tumor (9 cm in diameter: S7/S6/S8) with a hypervascular tumor stain. Transcatheter arterial chemoembolization (TACE) using degradable starch microspheres (DSM) plus mitomycin C, and hepatic arterial infusion (HAI) using high-dose 5-fluorouracil (5-FU) (6,000 mg/week), were performed 54 days before curative resection of the liver (S6+S7+S8+S5b/c). Histological findings revealed metastatic adenocarcinoma with a tumor thrombus in the posterior branch of the portal vein. The patient was treated with 2 courses of adjuvant chemotherapy with paclitaxel. No recurrence was observed 8 months after hepatectomy. This case suggests that combined treatment with TACE/HAI as a multimodal treatment might be effective in the management of hypervascular liver metastasis from gastric cancer.
