Adenoma News and Research

RSS

Adenoma (Benign Tumor) is a noncancerous tumor that starts in gland-like cells of the epithelial tissue (thin layer of tissue that covers organs, glands, and other structures within the body).

New study reveals the importance of bowel preparation prior to procedure

While there is little doubt concerning the effectiveness of colonoscopy procedures to detect colon cancer, a new study presented at the American College of Gastroenterology's 74th Annual Scientific Meeting in San Diego places new emphasis on the importance of adequate bowel preparation prior to procedure.

Some colonoscopic technologies better at improving detection of adenomas

Recent advances in colonoscopic technology are featured in a number of studies presented at the Annual Scientific Meeting of the American College of Gastroenterology this week. In this research some technologies fare better than others at improving detection of potentially pre-cancerous growths in the colon known as adenomas.

Clonality analyses may lead to further understanding of hepatocarcinogenesis

Focal nodular hyperplasia (FNH) is a lesion found in an otherwise normal liver, and is considered to be parenchyma overgrowth responsive to increased blood flow secondary to vascular malformations.

Inflammation markers not involved with the chemopreventative effect of aspirin on colorectal adenomas

Unexpectedly, inflammation markers do not appear to be involved with the chemopreventative effect of aspirin on colorectal adenomas, according to a brief communication published online October 12 in the Journal of the National Cancer Institute.

Studies suggest that serrated polyps can be precursors of colon cancers

Serrated colorectal polyps include the subgroups hyperplastic polyps, sessile serrated polyps (also called sessile serrated adenomas), and serrated adenomas. Recent studies have found that serrated polyps share molecular features with a subgroup of colon cancers, leading to the hypothesis that serrated polyps can be precursors of cancer through a hyperplastic polyp to serrated adenoma to cancer sequence.

Aspirin improves survival after colorectal cancer diagnosis

Men and women who were diagnosed with colorectal cancer and began regular use of aspirin had a lower risk of overall and colorectal cancer death compared to patients not using aspirin, according to a study in the August 12 issue of JAMA.

Giant pituitary adenoma can be safely removed through nasal route

It’s even worse than being told you have a brain tumor: having a tumor so large, it’s in a category all its own. Giant pituitary adenoma is a so-called “benign” tumor that can cause visual loss and impair many of the body’s most basic functions. But fortunately, even the largest of these giant tumors—which can grow to the size of an egg and invade nearby structures--can be treated effectively using a multimodality approach starting with minimally invasive surgery through the nose, according to a new study at the John Wayne Cancer Institute at Saint John’s Health Center.

Discovery of candidate tumor suppressor gene and potential biomarker for colorectal cancer

Researchers have identified a new candidate tumor suppressor gene in colorectal cancer and examined its use as a potential biomarker in stool samples, according to a new study published online June 17 in the Journal of the National Cancer Institute.

Discovery in colon cancer prevention

A new study finds that individuals who have low expression of the "Celebrex gene," 15-PGDH, are actually resistant to Celebrex treatment when used to prevent colon cancer.

Discovery of new pathway of tumourigenesis in humans

The first identification of GP130 somatic activating mutations in human tumours was announced today at EASL 2009, the Annual Meeting of the European Association for the Study of Liver Disease in Copenhagen, Denmark.

Liver tumors associated with metabolic syndrome differ from other tumors

Liver cancer in patients whose only risk factor is metabolic syndrome has distinct forms and structures compared to other liver tumors.

Reminders may increase colon cancer screening

Mailed reminders to patients appear to promote colon cancer screening, according to a report in the February 23 issue of Archives of Internal Medicine.

Smoking significantly linked to increased risk for colorectal cancer

An analysis of previous studies indicates that smoking is significantly associated with an increased risk for colorectal cancer and death, according to an article in the December 17 issue of JAMA, the Journal of the American Medical Association.

Narrow-band imaging comparable to white light colonoscopy in differentiating colorectal polyps

Researchers from Yale University School of Medicine compared narrow-band imaging (NBI) without high magnification to standard white light colonoscopy in differentiating colorectal polyps during real-time colonoscopy and found that NBI was not more accurate than white light colonoscopy.

Saturated fats a possible risk factor for cancer of the small intestine

Findings published in the journal Cancer Research, a journal of the American Association for Cancer Research, identify dietary intake of saturated fats as a possible risk factor for cancer of the small intestine, advancing the understanding of cancer development in this and other areas of the digestive tract.

Calcium may only protect against colorectal cancer in presence of magnesium

High magnesium intake has been associated with low risk of colorectal cancer. Americans have similar average magnesium intake as East Asian populations. If that were all that were involved, observers might expect both groups to have similar risk for colorectal cancer.

Innovative technology to improve colon cancer prevention

Researchers at NorthShore University HealthSystem (NorthShore) and Northwestern University have discovered that fiber optic technology can for the very first time effectively measure blood levels in the colonic lining (mucosa) in humans, thus having potential applications for analyzing risk of colon cancer. The study appears in the October 2008 issue of Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute.

Obesity raises risks of serious gastrointestinal diseases

The prevalence of obesity and overweight in the United States coupled by the increased risk of gastrointestinal diseases related to obesity raises serious implications for the health of Americans. Several scientific studies in the August issue of The American Journal of Gastroenterology examine the association between obesity and the risk of colorectal cancer and gastroesophageal reflux disease, or GERD.

Prevalence of pre-cancerous masses in the colon same in patients in their 40s and 50s

The prevalence of pre-cancerous masses in the colon is the same for average-risk patients who are 40 to 49 years of age and those who are 50 to 59 years of age, reports a new study in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute.
