In Vitro Fertilization and the Nobel Prize for Medicine

nobel medal in medicine

The 2010 Nobel Prize in Physiology or Medicine was announced on Monday. The prize was awarded to a British scientist for his role in developing human in vitro fertilization (IVF) therapy. IVF is a process by which egg cells are fertilized by sperm outside the body, in vitro.

Over the years, IVF has helped millions of infertile couples worldwide have children. Biologist and physiologist Robert G. Edwards, age 85, at the University of Cambridge, developed the technique with obstetrician and gynecologist Patrick Christopher Steptoe, who died in 1988. The prize is worth about $1.5 million and is the first awarded in the area of reproduction.

Addition of Immunotherapy Boosts Pediatric Cancer Survival

Administering a new form of immunotherapy to children with neuroblastoma, a nervous system cancer, increased the percentage of those who were alive and free of disease progression after two years. The percentage rose from 46 percent for children receiving a standard therapy to 66 percent for children receiving immunotherapy plus standard therapy, according to the study in the Sept. 30, 2010, New England Journal of Medicine. The randomized phase III clinical trial was coordinated by the Children’s Oncology Group (COG), a national consortium of researchers supported by the National Cancer Institute (NCI), part of the NIH.

Lifestyle Intervention Improves Risk Factors in Type 2 Diabetes

An intensive lifestyle intervention program designed to achieve and maintain weight loss improves diabetes control and cardiovascular disease risk factors in overweight and obese individuals with type 2 diabetes, according to four-year results of the Look AHEAD study, funded by the National Institutes of Health and the Centers for Disease Control and Prevention. The results are published in the Sept. 27, 2010, issue of the Archives of Internal Medicine.

Cancer Research Blog Carnival #38 – Breast Cancer

Welcome to the 38th edition of the Cancer Research Blog Carnival, the monthly blog carnival that discusses what’s new in cancer research. In recognition of October being Breast Cancer Awareness Month, this edition’s focus is on breast cancer.

There’s a revolution occurring on the Web: those “authoritative” articles written on traditional, static websites are being replaced with blogs, wikis and online social networks. In the sphere of health, medicine and information technology, this “real-time Web” consists of many who are professionals in the field; their posts are listed below.
In the digital age, these are the characteristics of new media: recent, relevant, reachable and reliable.
October is all about pink

Breast Cancer Awareness Month — also referred to as National Breast Cancer Awareness Month (NBCAM) — is an annual international health campaign organized by major breast cancer charities every October to increase awareness of the disease and raise funds for research into its cause, prevention and cure. The campaign also offers information and support to those affected by breast cancer.

In 2010, the American Cancer Society estimates that 207,090 women will be diagnosed with invasive breast cancer, approximately 54,010 women will be diagnosed with carcinoma in situ (CIS; the earliest non-invasive form of breast cancer), and approximately 39,840 women will die from breast cancer [1]. Indeed, breast cancer is the second leading cause of cancer death in women, following lung cancer.

In 1975, a woman had a 1 in 11 chance of developing invasive breast cancer some time in her life — today, the chance is even greater at 1 in 8. Although the risk has increased, deaths due to breast cancer have been declining: from 1990 — 2006, death rates decreased by 3.2% per year among women younger than 50, and by 2.0% per year among women 50 and older [2]. This decline in breast cancer mortality has been attributed to improvements in breast cancer treatment and early detection [3].

Animal research has contributed significantly to advances in breast cancer treatment. Animal studies were essential for the development of two front-line drugs that shrink breast cancer tumors, Herceptin and Tamoxifen. Since their mechanisms of action are different, they are used to treat different types of tumors. The drug Tamoxifen blocks tumor growth by blocking the action of estrogen, a hormone involved in the growth of most breast cancers. Tamoxifen binds to the estrogen receptor and blocks estrogen from docking to it. The drug Herceptin binds to another growth-regulating receptor protein called HER2, blocking it’s action and shrinking the tumor. Indeed, there is great value in animal research for the development of treatments to fight breast cancer.

Let’s find out what’s happening this month with breast cancer research.
