Cleveland Clinic researcher finds genetic mutation in castration-resistant prostate cancer
Date:8/29/2013

hese two categories and that DNA from some patient tumors also contains this mutation. The mutation works by opening the floodgates to androgen synthesis, essentially throwing fuel on the fire that promotes tumor progression.

In an era of personalized cancer care, there is increased focus on defining and treating cancer by its genetic abnormalities. Tumor-promoting enzyme mutations in several cancers have been identified and, subsequently, have led to the development of targeted drug therapies, improving outcomes for patients.

"The past decade has seen an explosion of molecularly targeted therapies that are matched to specific mutations in a given patient's tumor," says Dr. Sharifi. "However, no drug-targeting based on enzyme mutations exists for the standard treatment of metastatic CRPC. With this finding, we have the opportunity for matching a mutant disease-driving biomarker with a pharmacologic inhibitor."

Prostate cancer is the most common cancer in men, with nearly 240,000 new cases diagnosed each year in the United States. According to the American Cancer Society, there will be an estimated 30,000 deaths due to prostate cancer in 2013. Almost every man who dies of prostate cancer dies with castration-resistant prostate cancer.
