Fighting prostate cancer with tomato-rich diet

With 35,000 new cases every year in the UK, and around 10,000 deaths, prostate cancer is the second most common cancer in men worldwide. Rates are higher in developed countries, which some experts believe is linked to a Westernised diet and lifestyle. To assess if following dietary and lifestyle recommendations reduces risk of prostate cancer, researchers at the Universities of Bristol, Cambridge and Oxford looked at the diets and lifestyle of 1,806 men aged between 50 and 69 with prostate cancer and compared with 12,005 cancer-free men. …

Statistical Approach for Calculating Environmental Influences in Genome-Wide Association Study (GWAS) Results

The approach fills a gap in current analyses. Complex diseases like cancer usually arise from complex interactions among genetic and environmental factors. When many such combinations are studied, identifying the relevant interactions versus those that reflect chance combinations among affected individuals becomes difficult. In this study, the investigators developed a novel approach for evaluating the relevance of interactions using a Bayesian hierarchal mixture framework…

U.S. has seen widespread adoption of robot-assisted cancer surgery to remove the prostate — ScienceDaily

In 2001, surgeons began using robotic technologies in operations to remove the prostate. To examine trends in the use of such robotic-assisted radical prostatectomy (RARP) procedures for prostate cancer patients, Steven Chang, MD, MS, of Harvard Medical School, the Dana-Farber Cancer Institute, and Brigham and Women’s Hospital, led a team that analyzed 489,369 men who underwent non-RARP (i.e., open or laparoscopic radical prostatectomy) or RARP in the United States from 2003 to 2010. During the study period, RARP adoption (defined as performing more than 50 percent of annual radical prostatectomies with the robotic approach) increased from 0.7 percent to 42 percent of surgeons performing radical prostatectomies. Surgeons who performed at least 25 radical prostatectomies each year were more likely to adopt RARP…

New approach to identify ‘drivers’ of cancer developed — ScienceDaily

The study, published online August 24 in Nature Genetics, was authored by Michael Gatza, PhD, lead author and post-doctoral research associate; Grace Silva, graduate student; Joel Parker, PhD, director of bioinformatics, UNC Lineberger; Cheng Fan, research associate; and senior author Chuck Perou, PhD, professor of genetics and pathology. These researchers studied a variety of cancer causing pathways, which are the step-by-step genetic alterations in which normal cells transition into cancerous cells, including the pathway that govern cancer cell growth rates. A high growth rate of cells, also known as cell proliferation, is recognized to be associated with poor prognosis for breast cancer patients. Analyzing multiple types of genomic data, UNC Lineberger researchers were able to identify eight genes that were amplified on the genomic DNA level, and necessary for cell proliferation in luminal breast cancer, which is the most common sub-type of breast cancer…

Ovarian cancer: Know your body, know your risk — ScienceDaily

“There is no effective surveillance technique for the detection of early stage ovarian cancer, so the only effective way to prevent it and save lives is to identify women at risk,” said David A. Fishman, MD, Director of the Mount Sinai Ovarian Cancer Risk Assessment Program and Professor and Fellowship Director in the Division of Gynecologic Oncology, Department of Obstetrics, Gynecology and Reproductive Medicine at the Icahn School of Medicine at Mount Sinai. He recommends that women with a family history of ovarian and breast cancers get a formal genetic evaluation by a board-certified genetic counselor. For women who have tested positive for a BRCA mutation or are identified to be at a high risk for developing ovarian cancer, preventive surgery should be considered to remove the ovaries and fallopian tubes before ovarian cancer can develop. …

Symptoms after breast cancer surgery need to be treated on an individual basis — ScienceDaily

The authors state that it is crucial for good aftercare to understand and document a patient’s symptoms and target the treatment accordingly. Special attention will have to be paid to the risk of certain groups of patients: younger, premenopausal women suffer notably more from the effects of breast cancer than older women. In any case, women about to be given treatment for breast cancer should be given detailed information about late sequelae. source : http://www.sciencedaily.com/releases/2014/08/140826085730.htm
