A 72-year-old woman was diagnosed with liver dysfunction during a medical examination. An abdominal computed tomography (CT) scan showed multiple nodules in the left lobe, anterior segment, andposterior segment of the liver, leading to a diagnosis of intrahepatic cholangiocarcinoma (ICC). Extended left lobectomy and partial hepatectomy in the anterior and posterior segment with lymph node dissection was performed. At the time of the operation, small nodules on the peritoneum near the stomach were resected; these nodules were diagnosed as peritoneal disseminations of ICC. The histopathological diagnosis was moderately differentiated tubular adenocarcinoma (T4N0M1, Stage IVB). Adjuvant chemotherapy with S-1 was administered for 18 months. Thirty months after the operation, multiple lung metastases were detected by using CT, and chemotherapy with gemcitabine was initiated. Thirty-six months after chemotherapy with gemcitabine, the patient is alive and at home despite her lung metastases, which grew slightly in size. Herein, we report a long-term survival case of ICC with peritoneal dissemination that was successfully treated with surgical resection and adjuvant chemotherapy.

The N��el and the singlet RVB orders of the {\it t-J} model in a 2D square lattice are studied in the slave-boson mean-field approximation. It is shown that the N��el order parameter takes the maximum value at the finite temperature and disappear at the lower temperature for a certain range of doping. It is also shown that the N��el and the singlet RVB orders coexist at low temperature. This suggests the possibility of the coexistence of the N��el and the superconducting orders., RevTeX, 8 pages, 1 postscript figure. To appear in Physica C, Volume 257, issue 384
