A genome-wide association study identifies four genetic markers for hematological toxicities in cancer patients receiving gemcitabine therapy.

Objective: Genetic factors are thought to be one of the causes of individual variability in the adverse reactions observed in cancer patients who received gemcitabine therapy. However, genetic factors determining the risk of adverse reactions of gemcitabine are not fully understood.

Patients And Methods: To identify a genetic factor(s) determining the risk of gemcitabine-induced leukopenia/neutropenia, we conducted a genome-wide association study, by genotyping over 610 000 single nucleotide polymorphisms (SNPs), and a replication study in a total of 174 patients, including 54 patients with at least grade 3 leukopenia/neutropenia and 120 patients without any toxicities.

Anastomotic suture line recurrence of early rectal carcinomas that had been resected by laparoscopic surgery.

We report herein a case of a 64-year-old woman found to have anastomotic suture line recurrence of an early rectal carcinoma. The patient had undergone laparoscopy-assisted low anterior rectal resection for an early rectal carcinoma 2 years before the anastomotic site recurrence. A follow-up colonoscopy revealed an elevated lesion on the anastomotic suture line.

Isolated bacteria and susceptibilities to antimicrobial agents in biliary infections.

Background/aims: A total of 209 bacterial strains were isolated from patients with biliary infection in our department between January 1982 and December 2000.

Methodology: Antimicrobial susceptibility tests were conducted to ascertain the presence of drug-resistant bacteria.

Results: The breakdown of the 109 strains from the patients with primary biliary infections was as follows: 70 strains of gram-negative aerobic bacteria; 27 strains of gram-positive aerobic bacteria; 6 strains of gram-negative anaerobic bacteria; and 6 strains of gram-positive anaerobic bacteria.

Pancreas-sparing duodenectomy for a recurrent retroperitoneal liposarcoma: report of a case.

Pancreas-sparing duodenectomy (PSD), which allows preservation of the pancreas in its entirety, is a promising procedure for low-grade malignancies of the duodenum, the periampullary region, and the neighboring retroperitoneum. We report a case of recurrent retroperitoneal liposarcoma involving the second and third parts of the duodenum, which was extirpated using PSD, after a right hemicolectomy for tumor invasion of part of the colonic hepatic flexura. The Roux-en-Y jejunal limb was sutured to the duodenal bulb in an end-to-end fashion, and the biliary and pancreatic duct systems were reconstructed with end-to-side anastomoses, placing the jejunal limb distal to the bulbo-jejunostomy after a septoplasty to repair the adjacent pancreatic and biliary ducts.

[A case of pulmonary thromboembolism after cardiac surgery].

It has been reported that pulmonary thromboembolism (PTE) is a major complication in the post-operative period. However, there have been few reports on PTE after cardiopulmonary bypass (CPB). We report a case of PTE that occurred after cardiac surgery using CPB.

The p53 family member genes are involved in the Notch signal pathway.

The p53 tumor suppressor is a transcription factor that regulates cell growth and death in response to environmental stimuli such as DNA damage. p63/p51 and p73 were recently identified as members of the p53 gene family. In contrast to p53 however, p63 and p73 are rarely mutated in human cancers.
