Ten Israeli Advances in Fighting Breast Cancer
One out of every eight women will develop breast cancer in her lifetime. It is the most commonly diagnosed non-skin cancer in women worldwide, and also strikes thousands of men.
Though the three areas with the highest breast cancer rates are Western Europe, Australia/New Zealand and Northern Europe, Israel has taken a leading role in researching causes and treatments. The Breast Cancer Research Foundation’s very first international research grant was awarded in 2001 to Shaare Zedek Medical Center’s Dr. Ephrat Levy-Lahad to do a comprehensive Israeli Breast Cancer Study, now an international model for genetic breast cancer prevention screening.
In honor of Breast Cancer Awareness Month, it has presented a review of 10 of the most promising advances with the hope that breast cancer may soon be relegated to history:
1. IceSense 3
The cryoablation process takes five or 10 minutes in a doctor’s office, clinic or breast center under local anesthesia. No recovery period or post-care is necessary, and there is no scarring.
The Israeli company Real Imaging offers a no-radiation, no-contact alternative to mammography pioneered by electro-optical engineer Boaz Arnon and named in memory of his mother, who died of breast cancer in 2004.
RUTH uses a new trademarked platform that enables automatic quantitative analysis of 3D and infrared signals emitted from cancerous and benign breast tissue. Results are interpreted by computer, with unprecedented accuracy in patients of all ages — 90 percent as opposed to 80% for mammography. Thousands of women have been involved in clinical trials for RUTH since 2007. The next step is CE and FDA approval.
Dune Medical, a graduate of the Misgav Venture Accelerator, in June received pre-market approval from the US Food and Drug Administration for MarginProbe, its trademarked system that uses electromagnetic waves to identify possibly cancerous tissue on the edges of a breast tumor in real time. The application was based on data from a 600-patient study conducted primarily in the United States.
MarginProbe is meant to improve on the current rate of 30 percent to 60% of women who must undergo secondary breast cancer surgery after a lumpectomy because the initial surgery failed to get rid of all cancerous tissue at the margins of the tumor.
Herceptin, a frequently prescribed drug for blocking the chemical signals that stimulate uncontrolled growth of breast cancer cells, is one of an advanced class of pharmaceuticals called monoclonal antibody drugs. Currently, these drugs must be administered together with chemotherapy.
The two-year-old Israeli company Immune Pharmaceuticals is developing a “guided missile” system, licensed from the Hebrew University, which encloses thousands of chemotherapy molecules inside a monoclonal antibody nanoparticle. The drug payload isn’t released until reaching the cancerous tissue.
In addition, Immune is collaborating with the Weizmann Institute to develop antibody therapeutics targeting a growth factor that causes chemotherapy resistance in many patients with breast and ovarian cancer.
5. Better biomarkers
Tel Aviv University PhD student Livnat Jerby won a prestigious 2012 Dan David Scholarship for performing the first genome-scale study of the metabolic progression of breast cancer — an algorithm that can profile the traits of each individual patient’s tumor. These profiles help in studying the underlining mechanisms of the disease, classifying patients according to their prognosis and identifying potential metabolic biomarkers as a non-invasive, cost-effective means for early diagnosis and monitoring treatment efficiency.
“The Holy Grail of our work is to provide the basis for rational drug discovery, aiming to find drugs that — unlike most conventional treatments — will harm only the tumor, and not the healthy cells,” Jerby tells ISRAEL21c. “We had some success with providing a new potential target for treating renal cancer and published those results in Nature. With breast cancer, we can apply the same computational tools to better diagnose and choose the best treatment.
