  ABSTRACT: We report herein a case with stage IV gastric cancer previously treated with TS-1 completely responding to second-line chemotherapy with weekly paclitaxel therapy. A 65-year-old female was diagnosed as having type 3 gastric cancer with para-aortic lymph node metastases. She underwent total gastrectomy with extended lymph node dissection on March 2003. Histopathological examination revealed that the tumor was poorly-differentiated adenocarcinoma with para-aortic lymph nodes metastases and completely resected. After the operation,she was treated by adjuvant chemotherapy with TS-1. In March of 2004, she suffered from hematuria, and a CT scan revealed para-aortic lymph nodes metastases and left kidney metastasis. Then, she was treated by a weekly infusion of paclitaxel as second-line chemotherapy. After 3 courses, the tumor disappeared and efficacy was judged as CR. Moreover, CR was maintained after 7 courses. At this writing in January of 2005, she is well and has been treated with paclitaxel without any severe adverse events. Therefore, weekly paclitaxel therapy was considered to be one of the promising second-line chemotherapies for advanced or recurrent gastric cancer previously treated by TS-1.

  ABSTRACT: The patient was a 58-year-old female who had a cancer of the rectum with multiple lymph node metastases including paraaortic lymph nodes and Virchow lymph nodes. Abdominoperineal resection was performed palliatively. After the operation, weekly bolus of 5-fluorouracil combined with levofolinate was carried out. After 2 courses of chemotherapy, metastases of paraaortic lymph nodes and Virchow lymph nodes completely disappeared upon CT examination. Chemotherapy has continued for 14 months, and she is well and has maintained a complete response for more than 1 year. This case suggests that this combination chemotherapy of LV/5-FU, admitted in Japan, is effective against advanced colorectal cancer.

  ABSTRACT: The isolation of large-scale and high-quality islets from the pancreas is essential for a successful islet transplantation. We developed a hydroxyethyl starch (HES)-Collins solution as the purification medium and evaluated its usefulness on islet isolation from the pancreas of beagle dogs. The pancreas of beagle dog was digested using our original 2-step automated technique. Islets were purified by discontinuous purification method on HES-Collins solution (group 1, n = 10) or Euro-Ficoll solution (group 2, n = 16) with a COBE2991 cell processor. Islet yield and purity, changes in islet number during 3-day cultures, static incubation, perifusion study, and insulin content were examined. In addition, the islets were autotransplanted into the liver via the portal vein. Although no significant differences were detected, yield and purity were higher in group 1. After 3 days of culture, the islet number decreased less in group 1. Both under static incubation and in the perifusion study, stimulation indices were 4.50 +/- 1.82 and 6.02 +/- 1.05, which were significantly higher than the 2.18 +/- 0.67 and 3.32 +/- 1.46 observed in group 2. Also, insulin content of the islets was significantly higher in group 1 than in group 2. Fasting blood glucose levels were maintained at values below 100 mg/dl for 100 days in group 1 and around 200 mg/dl in group 2. The use of HES-Collins solution was associated with an improvement of islet yield and purity. Also, islet viability and function were preserved longer during culture. Accordingly, islet purification using HES-Collins solution might be recommended for clinical islet transplantation.
