[A case of S-1-resistant resected advanced gastric cancer with para-aortic lymph node recurrence responding to bi-weekly CPT-11 and CDDP].

A 64-year-old man with advanced gastric cancer who underwent a curative total gastrectomy(LM, Less, Type 3, 70×55 mm, por1>tub2>sig, pT3(ss), med, INF b, ly3, v3, pN3b(41/61), pPM0, pDM0, pT3N3bM0, Stage III B)followed by adjuvant chemotherapy(paclitaxel+S-1)a year ago, revealed an increasing level of serum CEA and para-aortic lymphnode (#16b1)recurrence on abdominal CT. He was given chemotherapy with low-dose weekday CDDP+S-1 for the recurrence, after which he failed to respond. Thereafter, he received 2nd-line chemotherapy with bi-weekly CPT-11+CDDP as a S-1- refractory regimen.

Effects of adenoviral-mediated hepatocyte growth factor on liver regeneration after massive hepatectomy in rats.

Resection is the only curative treatment for liver metastasis of colorectal cancers. Despite the supreme regenerative potential of the liver, major hepatectomy sometimes leads to liver failure, and the limitation of resectable liver volumes makes advanced tumors inoperable. This study was attempted to promote liver regeneration using hepatocyte growth factor (HGF) gene transfection by venous-administered adenovirus and to improve the survival of rats after massive hepatectomy.

Angiogenesis inhibitor TNP-470 can suppress hepatocellular carcinoma growth without retarding liver regeneration after partial hepatectomy.

Purpose: We investigated the suppressive effect of the angiogenesis inhibitor TNP-470 on accelerated hepatocellular carcinoma (HCC) growth in the regenerating liver.

Methods: After 70% partial hepatectomy (PH), AH-130 cells were injected into the portal vein of Donryu rats. A control group was given the vehicle only, and the treated group was given 10 mg/kg TNP-470 subcutaneously every second day, from 24 h after tumor implantation, seven times.
