Advances in Melanoma Highlighted at the 4th International Melanoma Congress

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) November 20, 2007 -- NEW YORK – The 2007 International Melanoma Congress marked a turning point in the search for new ways to battle this deadly cancer. The Congress gave a record-setting number of researchers the opportunity to discuss and share information about new therapies under investigation. The over 500 registrants of this year’s Congress signals the excitement generated by new understanding about the underlying genetic malfunctions that cause the cancer and the unprecedented opportunities to find novel therapies.

The meeting focused on information-sharing among leaders in the research community about the fundamental “errors” that occur in cells and discussion of therapies under investigation. Over 50 researchers offered their peers overviews and discussion forums that gave participants a compelling view into several trials that will likely culminate in the next 12-24 months.

“With the incorporation of new technologies into experimental and clinical research, we expect rapid advances in cutaneous melanoma prevention, diagnosis and therapy,” said Ze’ev Ronai, Ph.D., organizer of this year’s Congress and Program Director at the Burnham Institute for Medical Research. “We’re thrilled with the strong presence of researchers and clinicians at this meeting.”

A turning point in melanoma research occurred approximately five years ago with the first discovery of a gene mutation (BRAF) triggered a cascade of understanding about the genetic underpinnings of melanoma. Further research has shown that the disease is not simply one genetic malfunction, but rather more typically, a genetic malfunction paired with other disturbed pathways that cause disease.

Now the research community is poised to make unprecedented strides in the understanding about prevention and treatment of advanced melanomas. Clinical studies are already showing that new therapies are slowing down the progression of this fast-moving disease. In addition, basic science is revealing ways that existing drugs can be effectively used to turn back the disease.

David E. Fisher, M.D., PhD of the Dana Farber Cancer Institute, presented one such example. A patient with a mutation in a gene known as “c-KIT,” only identified by researchers a year ago, enrolled in a new clinical trial aimed at targeting the mutation with Gleevec. The drug is currently on the market and used to treat two other cancers including chronic myeloid leukemia (CML) and gastrointestinal stromal tumor (GIST). “This patient’s cancer exhibited a dramatic response to a single pill a day based upon accurate targeting of the drug to the mutation within the tumor—a first experience of this sort for melanoma,” said Dr. Fisher. While only about five percent of patients with advanced melanoma have the c-KIT mutation, this finding represents a promising new treatment pathway for those with the mutation, and indicates how growing understanding of genetic mutations is already yielding new treatments for other patients.
