Study by NH researchers could produce advances in breast cancer treatment

LEBANON — A new study by the Norris Cotton Cancer Center says cancer drugs developed for other forms of the disease could be used to successfully treat breast cancer.
Personalized Therapy for Breast Cancer was recently published online by Clinical Genetics. The study out of the Department of Pathology and the Department of Hematology-Oncology at the Geisel School of Medicine at Dartmouth in Hanover and the Dartmouth Hitchcock Medical Center and Norris Cotton Cancer Center in Lebanon, was conducted by researchers Francine B. De Abreu, Gary N. Schwartz, Wendy A. Wells and Gregory J. Tsongalis.
About 15 years ago doctors discovered that different types of breast cancers reacted differently to different treatments, Tsongalis said. Since then, the genetic makeup of breast cancer tumors have been used to tailor treatments for patients that would bring about the best possible outcome for that specific type of breast cancer.
In conducting the study, the researchers discovered that some of the subtypes have the same genetic defects that other cancers — such as melanoma or lung cancer — have, so drugs already developed for these different types of cancers could be used to successfully treat breast cancer patients, he said.
Tsongalis said he hopes the study furthers advancements in the treatment of breast cancer.
The study is already attracting attention from some patients that have contacted the center asking about the possibility of these new proposed treatments and/or clinical trials, he said.
