Scientists gained promising results Monday in treating colorectal cancer that has spread to the liver, showing that chemotherapy before and after surgery to remove liver tumors can help keep the disease in check.

Physiological differences between men and women may contribute to differential tumor development and progression in colon cancer patients, a study led by researchers at the University of Southern California (USC) suggests.

Patients with stage III colon cancer who have undergone surgery and chemotherapy with the goal of cure may have a higher risk of relapsing and dying early if they follow a predominantly "Western" diet of red meat, fatty foods, refined grains, and desserts, according to research led by investigators at Dana-Farber Cancer Institute in Boston. The findings were presented at the American Society of Clinical Oncology's annual meeting in Chicago.

The doctoral thesis Potencial terapéutico de nuevos fármacos antitumorales. Estudio sobre líneas celulares epiteliales (Therapeutic Potential of New Antitumor Drugs. A Study on Epithelial Cell Lines) has made it possible to develop six new drugs to fight colon and breast cancer more effectively than other drugs currently used do.

Scientists at Johns Hopkins have discovered one way the p53 gene does what it's known for-stopping the colon cancer cells. Their report will be published in the June 8 issue of Molecular Cell.

A colon cancer researcher at the Ireland Cancer Center of University Hospitals Case Medical Center (UHCMC) has laid out the roadmap for how medical science should employ aspirin and new aspirin-like drugs for use in preventing colon cancer in certain high-risk individuals.

To prevent colon cancer, the second leading cause of United States cancer deaths, the American Cancer Society recommends that after age 50 people undergo colonoscopies every ten years to detect signs of that disease - either actual tumors or precancerous polyps.

Colonoscopies are considered the gold standard for detecting colon cancer, the second leading cause of cancer deaths in the United States. Research presented today at Digestive Disease Week® 2007 (DDW®) discusses contributing factors that could prevent patients from getting optimal results from their colonoscopy, including age of the patient, location of the screening and proper technician training.

Research shows that the prevalence of obesity is rising, causing an increase in heart disease and diabetes, among other conditions, but evidence has not yet been established linking obesity to precancerous lesions in the colon called polyps. This study evaluated the effect of gender and obesity on the prevalence of colorectal polyps in a diverse population.

The American Gastroenterological Association (AGA) Institute is eager to increase the number of patients who receive screening for colon cancer. There are a variety of established screening methods that are widely available, and emerging technologies, such as computed tomography colonography (CT colonography), that are under investigation.

Correcting social, economic and healthcare inequalities may have the most significant impact in reducing survival differences in colorectal cancer (CRC) between African Americans and Caucasians, according to a new study.

Colon cancer could join the growing list of stem cell-related cancers with the discovery of a population of highly tumorigenic primary human colon tumor cells, according to researchers from Biogen Idec.
