BACKGROUND The neutrophil-lymphocyte ratio (NLR) reflects inflammatory status. An elevated NLR has been reported to be a prognostic indicator in some malignant tumors. The aim of this study was to evaluate the clinical significance of the preoperative NLR in patients with primary gastric cancer. METHODS A total of 709 men and 319 women, with a mean age of(More)
BACKGROUND Although many reports have described laparoscopic pancreatic surgery, pancreaticoduodenectomy (PD) has not been widely accepted. The present study aimed to compare laparoscopy-assisted and open pylorus-preserving pancreaticoduodenectomy (PPPD) to investigate the feasibility, safety, and tumor clearance. METHODS Fifteen patients with(More)
OBJECTIVES The purposes of this study were to investigate the prevalence and distribution of intervertebral disc degeneration (DD) over the entire spine using magnetic resonance imaging (MRI), and to examine the factors and symptoms potentially associated with DD. DESIGN This study included 975 participants (324 men, mean age of 67.2 years; 651 women,(More)
BACKGROUND NSABP C-06 demonstrated the non-inferiority of oral adjuvant uracil and tegafur plus leucovorin (UFT/LV) to weekly fluorouracil and folinate (5-FU/LV) with respect to disease-free survival (DFS) for stage II/III colon cancer. This is the first report of JCOG0205, which compared UFT/LV to standard 5-FU/levofolinate (l-LV) for stage III colorectal(More)
Histological examination of gonads as well as chemical analysis of organotin compounds in tissues of the giant abalone, Haliotis madaka, was conducted to evaluate possible endocrine disruption and to consider the causal factors for the decline of abalone stocks in Japan. Abalone specimens were collected from two different areas, Tsushima as a reference site(More)
BACKGROUND Epstein-Barr virus (EBV), the etiological agent of infectious mononucleosis, has an important role in the oncogenesis of EBV-related malignant diseases. The association of EBV with gastric carcinoma cells has become well known recently, but there are only a few reports concerning its association with surrounding epithelia and infiltrating(More)
BACKGROUND Hangeshashinto (TJ-14, a Kampo medicine), which reduces the level of prostaglandin E2 and affects the cyclooxygenase activity, alleviates chemotherapy-induced oral mucositis (COM). We conducted a randomized comparative trial to investigate whether TJ-14 prevents and controls COM in patients with gastric cancer. METHODS We randomly assigned(More)
PURPOSE Hyperbaric oxygen (HBO) has been shown to increase tumor radiosensitivity. Several reports indicate that it also increases sensitivity to alkylating agents, but other reports suggest that it may speed angiogenesis and tumor growth. To throw light on these questions, we investigated the effects of HBO and 5-fluorouracil (5-FU), individually and in(More)
Serous cystic neoplasms (SCN) of the pancreas are typically honeycombed microcystic masses, which are believed to be benign entity. This report describes a case of a 69-year-old man with a rare solid type of serous cystadenocarcinoma of the pancreas with liver metastases. A 6-cm well enhanced pancreatic tumor and multiple liver nodules were depicted with(More)
Although many reports have described laparoscopic pancreatic surgery, laparoscopic pancreaticoduodenectomy (PD) has not been widely employed because of technical difficulties. This paper describes a totally laparoscopic pylorus-preserving PD performed for an intraductal papillary-mucinous neoplasm. After the laparoscopic resection, an end-to-side(More)
