Among 256 consecutive subjects so far studied in our laboratory, we found one subject (a 63-year-old female) whose very low density lipoprotein (VLDL) and high density lipoprotein (HDL) contained unusually high amounts of apolipoprotein C-III-O among apolipoprotein C-III polymorphic forms. Identification of apolipoprotein C-III-O was achieved by a(More)
BACKGROUND/AIM We investigated the relationship between the expression of natural killer group 2, member D ligands (NKG2DLs) and the antitumor effects of protein-bound polysaccharide-K (PSK). MATERIALS AND METHODS PSK was administered to evaluate its effectiveness against tumor growth. The expression of Rae-1 and H60 were analyzed in multiple cell lines.(More)
We report a rare case of esophageal carcinoma with an aberrant right subclavian artery. A 67-year-old woman was admitted to our hospital because of a sense of discomfort during swallowing. A detailed gastrointestinal examination revealed advanced carcinoma of the middle thoracic esophagus. Preoperative CT also revealed an aberrant right subclavian artery(More)
We report a case of remnant pancreatic cancer after pancreatoduodenectomy that was successfully treated using chemotherapy and carbon-ion radiotherapy. A 68-year-old woman received SSPPD for pancreatic head cancer. Gemcitabine(GEM) was administered for a year as postoperative chemotherapy. One year 8 months after surgery, abdominal CT showed a 20 mm solid(More)
BACKGROUND Regulatory T-cells (Tregs) actively engage in the maintenance of immunological self-tolerance and immune homeostasis. The purpose of the present study was to determine how oxaliplatin plus infusional 5-fluorouracil and leucovorin (FOLFOX) and irinotecan plus infusional 5-fluorouracil and leucovorin (FOLFIRI) affect Tregs and other immune(More)
Herein, we report a case of esophageal cancer with lung metastases that was successfully resected after chemotherapy. A 61-year-old man was diagnosed with a middle thoracic esophageal squamous cell carcinoma showing lung metastases. The clinical Stage diagnosis was T4NxM1, Stage IVb. After systemic chemotherapy with 1 course of cisplatin/5-fluorouracil(More)
A 72-year-old man was admitted to our hospital because of anal discomfort. A detailed gastrointestinal examination revealed both left cholangiocellular carcinoma and rectal cancer. We performed endoscopic mucosal resection (EMR) for the rectal cancer. Pathological findings suggested the possibility of residual cancer after EMR. The cholangiocellular(More)
A 52-year-old woman was admitted to our hospital because of melena and right abdominal pain. Detailed gastrointestinal examination revealed ascending colon cancer. She underwent laparoscopic-assisted right hemicolectomy and D3 lymphadenectomy using 5 ports. After surgery, the patient refused adjuvant chemotherapy. Outpatient follow-up was periodically(More)
We report a rare case of male hereditary breast cancer in which a sentinel lymph node biopsy was performed. A 62-yearold man was admitted to our hospital because of a palpable tumor in his right breast. Both his younger sister and daughter had had breast cancer. Genetic testing revealed a morbid mutation in the BRCA2 gene. The tumor was palpated to an(More)
