BACKGROUND/AIMS The present study was conducted to investigate the relationship between bone metabolic disorder after gastrectomy for gastric cancer and vitamin D metabolites or the hormones involved in calcium metabolism. METHODOLOGY Twenty-one patients who had undergone gastrectomy for gastric cancer and had been followed for less than 10 years were(More)
We report the successful management of multiple small-bowel perforations caused by cytomegalovirus (CMV) infection in a 60-year-old man, 1 day after CHOP (cyclophosphamide/doxorubicin/vincristine/prednisone) therapy induction for malignant lymphoma. Emergency laparotomy was performed for perforative peritonitis, but we did not resect the lesions at this(More)
BACKGROUND Surgical samples have long been used as important subjects for cancer research. In accordance with an increase of neoadjuvant therapy, biopsy samples have recently become imperative for cancer transcriptome. On the other hand, both biopsy and surgical samples are available for expression profiling for predicting clinical outcome by adjuvant(More)
In esophageal squamous cell carcinoma (ESCC), chemoradiotherapy (CRT) has a curative potential even in cases of locally advanced carcinoma. However, only about half of the patients benefit from CRT, and an accurate prediction of sensitivity to CRT is eagerly awaited. Using microarrays, we analyzed gene-expression patterns of pretreatment biopsy specimens(More)
BACKGROUND/AIMS We investigated whether sentinel lymph node biopsy using dye technique alone is useful or not in decision-making for less invasive surgery in patients with gastric cancer. METHODOLOGY The subjects were 43 patients who had undergone laparotomy for gastric cancer and consented to undergo sentinel lymph node biopsy using patent blue dye. The(More)
A 52-year-old woman visited our hospital with epigastralgia. Detailed examination revealed a duodenal cancer of the ascending limbs. Since she refused the resection, the administration of S-1 alone was commenced. After one course of this treatment, oral intake became impossible. Duodenography and endoscopy showed duodenal obstruction, and she underwent(More)
BACKGROUND Recently, some studies have suggested that sentinel node biopsy also can be applied to gastric cancer. The authors apply sentinel lymph node biopsy in laparoscopy assisted distal gastrectomy to perform it as safe limited surgery. Limited surgery is a procedure in which the extent of lesion resection and lymph node dissection is reduced. The(More)
nosed segment III infarction due to liver abscess, because CT scan showed the cluster sign characteristic of a liver abscess [1, 2]. We performed an operation for lavage and drainage (fig. 2). Nine days later, CT examination revealed that the abscess cavity had become smaller and the infarction area had a transformed abscess (fig. 1 b). Five months later,(More)
