New research findings may enable earlier diagnosis of uterine cancerJanuary 28, 2009Cancer is a genetic disease. It occurs when changes take place in the genes that regulate cell division, cell growth, cell death, cell signalling and blood vessel formation - either due to mutations caused by external factors such as smoking or radiation - or due to inherited changes. This interaction between defective genes and environmental factors means that cancer is an extremely complex disease. Cancer of the uterus, or endometrial carcinoma, is no exception. Cancer of the uterus is the commonest gynaecological malignancy in the West and accounts for between five and six per cent of all cancers in Swedish women. However, the symptoms are often vague, and we know little about the genetic factors that lead to the appearance and development of this form of cancer. It is therefore vital that these genes are identified, as this could enable doctors to make the diagnosis much more quickly and easily, allowing the development of more effective cancer treatment. In her study, Sandra Karlsson, a researcher at the Department of Cell and Molecular Biology, has used inbred rats to locate the defective genes that cause uterine cancer. Like monozygotic (identical) twins, these inbred rats are genetically almost identical, which makes it much easier to study the influence of the environment in which they live. "More than 90 per cent of the female rats in the study spontaneously developed uterine cancer. By using advanced techniques to analyse gene expression in the tumours, we succeeded in identifying a gene signature that could be used as a future diagnostic test for human uterine cancer," says Sandra Karlsson. The signature is made up of three genes. One of them protects the cell against oxygen free radicals. These free radicals are naturally and continuously produced in the cell, but excess amounts, which can damage the cell and the body's DNA, are associated with over 200 diseases, from arteriosclerosis and dementia to rheumatism, cerebral haemorrhage and cancer. The studies carried out by Sandra Karlsson on human malignant tumours have confirmed that changes in this gene are present in early as well as late stage cancer. "This shows that the identified gene has an important role in the origin and development of uterine cancer," says Sandra Karlsson. University of Gothenburg |

New drug aims to 'seek and destroy' many types of cancer A new drug designed to "seek and destroy" common cancers such as breast, prostate, endometrial, pancreatic, ovarian, skin and testicular cancers is being tested at TGen Clinical Research Services (TCRS) at Scottsdale Healthcare. Study identifies how tamoxifen stimulates uterine cell growth and cancer UCSF researchers have identified a new "feed-forward" pathway linking estrogen receptors in the membrane of the uterus to a process that increases local estrogen levels and promotes cell growth. Black women with uterine cancers more likely to die than white patients Black women with cancers of the uterus are less likely to survive the disease than white women, and relatively little progress has been made over the past two decades to narrow this racial difference. That is the conclusion of a new study published in the March 15, 2009 issue of CANCER, a peer-reviewed journal of the American Cancer Society. 2 new compounds show promise for eliminating breast cancer tumors Two new compounds created by a University of Central Florida professor show early promise for destroying breast cancer tumors. Hormone drug type makes survival difference in advanced breast cancer Aromatase inhibitors, a type of hormone therapy used to treat advanced breast cancer in postmenopausal women, result in a small but significant increase in overall survival when compared to other hormone treatments, according to a new systematic review of studies. Two new studies reveal benefits of laparoscopic surgery for uterine cancer In a pair of studies presented today at the Society of Gynecologic Oncologists 37th Annual Meeting on Women's Cancer, researchers have found in a large randomized trial of laparoscopy versus laparotomy for surgical treatment of uterine (endometrial) cancer that laparoscopy is safe, and when successfully completed reduces hospital stay by 50 percent, and contributes to a better quality of life from the patient's perspective. Studies find no evidence that estrogens in soy increase uterine cancer risk Studies in monkeys and women suggest that unlike traditional estrogen therapy, a diet high in the natural plant estrogens found in soy does not increase the risk of uterine cancer in postmenopausal women. Yale procedure cuts recurrence of aggressive uterine cancer A state-of-the-art treatment program developed at Yale School of Medicine increases survival from the aggressive uterine papillary serous carcinoma (UPSC) and spares some patients the need for additional therapy. Detection of glycoprotein could identify ovarian and uterine cancers with poor prognosis (p 865) Issue 13 September 2003 Embargoed 0001 h (London time) 12 September 2003. The detection of a specific protein molecule could help oncologists identify uterine and ovarian cancers with poor prognosis and thereby enable better disease management of women with aggressive uterine or ovarian cancer, suggest authors of a study in this week's issue of THE LANCET. Ovarian and uterine cancer is the most common cause of death from cancer-related deaths for women with gynaecological malignant disease. The prognosis for women with uterine cancer is usually better than for women with ovarian cancer; however some women will develop aggressive tumours in either disease which increases the risk of death.
