Scientists have located a region of DNA that - when altered - can increase the risk of ovarian cancer, according to research published in Nature Genetics. An international research group, including scientists from Moffitt Cancer Center, searched through the genomes of 1,817 women with ovarian cancer and 2,353 women without the disease from across the UK. They analyzed 2.

Many women at high risk for breast or ovarian cancer are choosing to undergo surgery as a precautionary measure to decrease their cancer risk, according to a report in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research. "Women have their breasts or ovaries removed based on their risk.

The following summarizes recent articles on breast and ovarian cancer research.~ Breast cancer: For the first time, a large international breast cancer study to determine the effectiveness of radiation therapy after mastectomy will include 200 Chinese women, the New York Times reports. Asian women traditionally have had relatively low breast cancer rates.

Ovarian cancer is any cancerous growth that may occur in different parts of the ovary. The majority of ovarian cancers arise from the epithelium (outer lining) of the ovary. According to the American Cancer Society it is the 8th most common cancer among women in the USA (excluding non-melanoma skin cancers). In the UK ovarian cancer is the fifth most common cancer among females, after breast cancer, bowel cancer, lung cancer and uterine cancer (cancer of the uterus).

By searching millions of DNA variations in the genomes of thousands of women with and without ovarian cancer, scientists have discovered a previously undetected region of DNA which when altered, can increase a woman's risk of developing ovarian cancer by 40 per cent. The hope is that this will one day lead to a reliable screening test for a disease that currently has a high mortality rate because it is difficult to detect early.

Tiny particles carrying a killer gene can effectively suppress ovarian tumor growth in mice, according to a team of researchers from MIT and the Lankenau Institute. The findings could lead to a new treatment for ovarian cancer, which now causes more than 15,000 deaths each year in the United States. Because it is usually diagnosed at a relatively late stage, ovarian cancer is one of the most deadly forms of the disease. The new treatment, reported in the Aug.

The following summarizes recent research related to ovarian cancer.~ Early periods linked to lower survival: Women who start menstruating at an early age or experience more menstrual cycles over their lifetimes appear to have a lower chance of surviving ovarian cancer, according to a

Nanoparticle delivery of diphtheria toxin-encoding DNA selectively expressed in ovarian cancer cells reduced the burden of ovarian tumors in mice, and researchers expect this therapy could be tested in humans within 18 to 24 months, according to a report in Cancer Research, a journal of the American Association for Cancer Research.

With a novel therapeutic delivery system, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center has successfully targeted a protein that is over-expressed in ovarian cancer cells. Using the EphA2 protein as a molecular homing mechanism, chemotherapy was delivered in a highly selective manner in preclinical models of ovarian cancer, the researchers report in the July 29 issue of the Journal of the National Cancer Institute.

A novel anticancer agent, consisting of a monoclonal antibody linked to a chemotherapy drug, showed substantial antitumor activity in ovarian cancer cell lines and in mice, according to a study published online July 29 in the Journal of the National Cancer Institute. The agent, known as an immunoconjugate, targets a protein, EphA2, which is overexpressed in many human cancers but is absent or expressed at low levels in normal tissues. Anil K. Sood, M.D.

Scientists in the US have found a way of slowing the growth of ovarian cancer tumors in mice by using nanoparticles to deliver suicide genes to the exact tumor location without damaging healthy cells. They hope a therapy using this method could be tested in humans within the next two years.

CytRx Corporation (NASDAQ: CYTR), a biopharmaceutical research and development company engaged in the development of high-value human therapeutics, announced that results demonstrating that its cancer drug candidate INNO-206 caused statistically significant tumor shrinkage in an animal model of ovarian cancer have been accepted for publication in the peer-reviewed journal Investigational New Drugs.

Ovarian cancer kills approximately 15,000 women in the United States every year, and more than 140,000 women worldwide. Most deaths from ovarian cancer are caused by tumors of the serous histological type, which are rarely diagnosed before the cancer has spread.

Current diagnostic tests for ovarian cancer are woefully ineffective for early detection of the disease, say researchers at Stanford University School of Medicine. A new study finds that in order to make a significant dent in the mortality rate for the deadly cancer, the tests would have to be able to detect tumors of less than 1 cm in diameter, or about 200-times smaller in mass than those currently used to assess potential new tests.

Scientists in the US suggest that current tests for diagnosing ovarian cancer are not good enough and we need to develop better ways of detecting the disease much earlier. The study is published on 28 July in the open access journal Public Library of Science and is the work of researchers from Stanford University School of Medicine and the non-profit Canary Foundation, an organization dedicated to the early detection of many types of cancer.

Two new studies reveal a way to increase the body's appetite for gobbling up the cancer stem cells responsible for acute myeloid leukemia (AML), a form of cancer with a particularly poor survival rate. The key is targeting a protein on the surface of those cells that sends a "don't eat me" signal to the macrophage immune cells that serve as a first line of defense, according to the reports in the July 24th issue of the journal Cell, a Cell Press publication.

The National Cancer Institute has awarded a five-year, $2.8 million Research Project (RO1) grant to Roswell Park Cancer Institute http://www.roswellpark.org/ (RPCI) researchers to investigate the role of immunological pathways in the development of ovarian cancer. Roswell Park investigators are

Women who have premature menopause because of medical interventions are at an increased risk of developing lung cancer, according to a new study published in the International Journal of Cancer. The startling link was made by epidemiologists from the Université de Montréal, the Research Centre of the Centre Hospitalier de l'Université de Montréal and the INRS-Institut Armand-Frappier.

In a feat of trickery, Dartmouth Medical School immunologists have devised a Trojan horse to help overcome ovarian cancer, unleashing a surprise killer in the surroundings of a hard-to-treat tumor. Using nanoparticles--ultra small bits-- the team has reprogrammed a protective cell that ovarian cancers have corrupted to feed their growth, turning the cells back from tumor friend to foe.
