[A case of a colon cancer patient with liver metastasis subjected to hepatectomy after achieving radiographic complete response with preoperative chemotherapy].

In 2006, a 70-year-old man who underwent low anterior resection for rectal cancer (SS, N0, H1, Stage IV)at a nearby hospital was referred to our hospital. He was noted to have multiple liver metastases of approximately 1 cm in diameter in S2, S3, S6, and S7, and was subsequently treated with chemotherapy for 5 courses of mFOLFOX6 regimen. He achieved a complete response radiographically.

Feasibility and accuracy of second-look laparoscopy after gastrectomy for gastric cancer.

Background: A better method for detecting early peritoneal progression is needed. This study evaluated the feasibility and accuracy of second-look laparoscopy for patients with gastric cancer treated using systemic chemotherapy after gastrectomy.

Methods: Second-look laparoscopy was conducted for patients who had no clinical evidence of distant metastases but had peritoneal metastases or positive peritoneal cytology results without visible metastatic disease at initial surgery, patients who underwent systemic chemotherapy over a 6-month period after surgery, and patients who had no clinical evidence of disease based on imaging study after completion of primary chemotherapy.

Characterization of Salmonella isolated in Okinawa, Japan.

Salmonella enterica strains isolated in Okinawa between 1995 and 2005 were analyzed with respect to their serovars and antimicrobial susceptibility, and pulsed-field gel electrophoresis (PFGE) was used to examine their digestion patterns. A total of 1,071 isolates, including 610 from humans, 358 from animal rectal swabs and 103 from meat obtained at grocery stores, were examined. The first 3 most frequent serovars in human isolates were Enteritidis, Weltevreden and Bareilly, together accounting for 65% of the isolates.
