OBJECTIVE Surgical resection has been the first choice of treatment for resectable pulmonary metastases from colorectal cancer. However, early intrapulmonary recurrence is often observed and appropriate assessment of prognostic factors is controversial. The aim of this study was to define the factors affecting survival and intrapulmonary recurrence after(More)
BACKGROUND Single-port laparoscopic surgery is a new technique that leaves no visible scar. This new technique has generated strong interest among surgeons worldwide. However, single-port laparoscopic colon surgery has not yet been standardized. Our aim in this study was to evaluate the feasibility of single-port laparoscopic colectomy compared with(More)
AIM Many studies support the role of carcinoembryonic antigen (CEA) as a strong indicator of the status of colorectal cancer patients, but evidence for carbohydrate antigen 19-9 (CA19-9) is poor. For this reason the study aimed to evaluate the prognostic value of preoperative serum CA19-9 levels in colorectal cancer patients. METHOD In all, 1190(More)
The caudal-related homeobox transcription factor CDX2 has a key role in intestinal development and differentiation. CDX2 heterozygous mutant mice develop colonic polyps, and loss of CDX2 expression is seen in a subset of colon carcinomas in humans. Ectopic CDX2 expression in the stomach of transgenic mice promotes intestinal metaplasia, and CDX2 expression(More)
The gastrointestinal tract is continuously exposed to a variety of chemicals and commensal bacteria. Recent studies have shown that changes in gut microbial populations caused by chlorine or other chemicals in the drinking water influence the development of human colorectal cancer, although the mechanism of tumorigenesis in the gut epithelium is obfuscated(More)
PURPOSE Surgical site infection (SSI) is a frequent complication of elective surgery for colorectal cancer. The classical clinical markers of infection-elevations in white blood cell count, C-reactive protein (CRP) level, and body temperature-do not precisely predict SSI after elective colorectal resection. The objective of this study was to evaluate the(More)
BACKGROUND Hypoxia inducible factor-1α (HIF-1α) is a major regulator of tumorigenesis in hypoxic conditions and therefore represents a potential therapeutic target in colorectal cancer (CRC). Clinical significance of HIF-1α expression in liver metastases has not been elucidated. Therefore, this study aimed to clarify the clinical significance of HIF-1α(More)
BACKGROUND Necrotizing fasciitis of the thigh due to the colon cancer, especially during chemotherepy, has not been previously reported. CASE PRESENTATION A 67-year-old man admitted to the hospital was diagnosed with sigmoid colon cancer that had spread to the left psoas muscle. Multiple hepatic metastases were also found, and combination chemotherapy(More)
PURPOSE This study aimed to assess the prognostic value of the lymph node ratio (LNR), estimated by dividing the number of positive lymph nodes (LNs) by the number of LNs examined, for stage III colorectal cancer in comparison to the new tumor, nodes, and metastasis (TNM) system, and to evaluate the relationship between the number of LNs examined and the(More)
