The registry of digestive tract tumours established for the department of Cote d'Or (France) was used to study the epidemiological characteristics of large bowel cancer subsites for the period 1976-1983. Age standardised incidence rates for colon cancers were 18.9/100,000 for men and 14.2/100,000 for women. The corresponding rates for rectal cancers were 18.4/100,000 and 10.2/100,000. The sex r...
BACKGROUND In metastatic colorectal cancer, the location of the primary tumor has been suggested to have biological significance. In this study, we investigated whether primary tumor location affects cetuximab efficacy in patients with RAS wild-type metastatic colorectal cancer. METHODS Genotyping by the SequenomMassARRAY technology platform (OncoMap) targeting KRAS, NRAS, PIK3CA, and BRAF wa...
Vitamin D deficiency is a common problem worldwide. In particular, it is an issue in the Northern Hemisphere where UVB radiation does not penetrate the atmosphere as readily. There is a correlation between vitamin D deficiency and colorectal cancer incidence and mortality. Furthermore, there is strong evidence that cancer of the ascending (right side) colon is different from cancer of the desce...
Increasing evidence suggests genetic, biological and demographical difference between right and left colon cancer. Studies have also indicated age differences in the pathology of colon cancer. There is a scarcity of large-scale studies that closely examine the pathological differences regarding age and tumor location. The aim of this study was to do an extensive comparison of rightand left-side...
a mobile caecum and ascending colon is an uncommon congenital disorder, and it is even rarer as the cause of an acute abdomen during childhood. this report presents the case of a 6-year-old boy with acute gangrenous appendicitis with a mobile caecum and ascending colon. data from the surgical course, as well as laboratory and imaging studies, were acquired and carefully examined. emergency ultr...
Background and Purpose: Each year, about 50,000 new cases of cancer occur in Iran and the most common being the gastrointestinal (GI) tract (38%). Colorectal cancers account for the 3rd and 4th most prevalent cancers in Iranian men and women, respectively. Since genetic and environmental factors lead to differences in colorectal cancer occurrence in different geographic regions and races, we ...
BACKGROUND/AIMS The purpose of this study was to evaluate the clinicopathologic characteristics of colon cancers detected at the SOK Sokpeynhan Internal Medical Network, a nationwide system of primary health care institutions. METHODS We analyzed 579 colon cancer patients diagnosed using colonoscopy at the SOK network from January 2011 through December 2012. Cancers from the rectum to the spl...
BACKGROUND Alterations in epithelial proliferation and apoptosis in colonic mucosa are associated with an increased risk of colon cancer. It is unclear if these alterations represent a generalised "field defect". AIMS To analyse segmental patterns of cell proliferation and apoptosis in the colon of subjects with a high and no apparent risk of colon cancer. METHODS Pancolonoscopy was perform...
Purpose: To evaluate the incidence and different potential risk factors for development of anastomotic leakage (AL) after resection left-sided colon cancer. Also, to AL impact on long-term survival outcomes.
Spontaneous rupture of colon cancer, combined with psoas abscess formation, is rare. A 44-year-old male visited for back pain and left buttock mass. Abdominal computed tomography and magnetic resonance image revealed a large abscess in the left psoas muscle and in the left lower quadrant area. Ten days after incision and drainage, a skin defect around the left anterior superior iliac spine rema...
