SAN FRANCISCO, Sept. 16, 2013 (GLOBE NEWSWIRE) -- Pearl Yee, MD, FACOG and clinical professor at the University of California, San Francisco, is pleased to announce that her private practice, Pearl W. Yee, M.D. Inc, in San Francisco is now offering the BREVAGen™ predictive risk test. Clinically validated, BREVAGen is the latest advance in assessing a woman's unique risk of developing non-familial or sporadic breast cancer.

"Personalized medicine and genetic screening have evolved, and we now have the tools to fuel one of my greatest passions, which is preventing cancer. I now expect my patients to live well into their 90s. With proper medical insights using tests like BREVAGen, we can help women understand their personal risk of developing cancers such as breast cancer; better understand their personal risk of using hormone replacement therapies; and, avoid unnecessary testing," said Dr. Yee. "Having pioneered the use of robotic surgery and minimally invasive surgery, I'm passionate about utilizing new technology to improve patient care. BREVAGen helps us understand each patient's risk so we can then develop personalized breast health and monitoring plans tailored to their specific risk and needs. BREVAGen helps me identify women who might need more frequent testing and those who might require less. This will help reduce the incidence of advanced breast cancer cases we see, help save lives and help control medical costs."

BREVAGen is a clinically validated predictive risk test that more accurately identifies a woman's unique risk of developing sporadic, estrogen-positive breast cancer. BREVAGen examines a woman's clinical risk factors, such as their lifetime exposure to estrogen, combined with scientifically validated markers to determine each patient's personalized five-year and lifetime risk of developing breast cancer.1 BREVAGen is supplied by Phenogen Sciences, a subsidiary of Genetic Technologies Limited (Nasdaq:GENE). For more information about BREVAGen at Pearl W. Yee, M.D., Inc., contact the office at (415) 405-0200.

How BREVAGen Works

The BREVAGen predictive risk test is administered in a physician's office using a simple, non-invasive "oral-swab." Following analysis in a CLIA-certified laboratory, physicians receive a comprehensive genetic risk prediction report to review with the patient.

The patient's risk of breast cancer is calculated by combining their relative risk score from seven genetic markers, called SNPs (single nucleotide polymorphisms), with factors that comprise the patient's clinical and reproductive history including current age, age at menarche, age at live first birth and race/ethnicity.

The BREVAGen test provides five-year and lifetime predictive risk assessments to more accurately evaluate the patient's risk for developing sporadic breast cancer, regardless of family history or previous indeterminate test results.

Clinically Validated

BREVAGen was proven superior in determining breast cancer risk compared to Gail score alone.1 Utilizing data from the U.S. Women's Health Initiative (WHI) Clinical Trial, 3,300 women underwent breast cancer assessment utilizing the BREVAGen test. Of those 3,300 women, 1,664 were diagnosed with breast cancer and 1,636 were in the breast cancer-free control group. BREVAGen test results support current American Cancer Society (ACS),, American Society of Clinical Oncology (ASCO),, and The National Comprehensive Cancer Network (NCCN),, guidelines for prevention and early detection of breast cancer.2, 3

Additional Information

About Breast Cancer

  • Approximately one in eight women will get breast cancer4
  • 70% to 80% of those who get breast cancer do not have familial risk indicators2
  • Risk of invasive vs. non-invasive breast cancer is approximately four times greater in women age 40-645
  • Approximately 75% of all breast cancer is estrogen-positive and, if detected early, can be effectively treated with five-year survival rates of over 95%

Breast Cancer Demographics

According to the American Cancer Society, breast cancer is the most common cancer among women in the United States, other than skin cancer.  It is the second leading cause of cancer death in women, after lung cancer.4  According to the 2010 breast cancer demographics there are:

  • Approximately 207,000 new cases diagnosed each year4
  • Of the 207,000 new cases, about 54,000 are non-invasive forms of breast cancer that have been diagnosed early4
  • Approximately 40,000 deaths related to breast cancer in women, annually4

BREVAGen reclassified 64% of above average Gail risk subjects1

BREVAGen reclassified 64% of Gail scores above average risk subjects as either high or low risk for development of hormone-dependent breast cancer.  Furthermore, the BREVAGen test reclassified the breast cancer risk for 33% of the total 3,300 trial subjects.1
About BREVAGen™

The first product in Phenogen Science's portfolio, BREVAGen™ is a predictive risk test for sporadic, hormone-dependent breast cancer.  The BREVAGen test combines a woman's clinical history of estrogen exposure with the presence of identified genetic markers to determine her five-year and lifetime risk for developing breast cancer.  For women whose clinical profile indicates prolonged estrogen exposure, BREVAGen helps to provide a more accurate risk assessment for estrogen-positive breast cancer.  The test results assist physicians in developing a personalized care path toward managing each woman's risk of developing breast cancer with greater precision than ever before.

  • Non-invasive, easy-to-use predictive risk assessment test
  • The first genetic risk prediction test to have been validated in a large-scale, peer-reviewed, case-controlled study1
  • Recent studies demonstrate that 64% of women who have above average risk of prolonged estrogen exposure were either reclassified above the guidelines for high risk management or below the general population risk when compared to clinical risk factors alone1
  • Supports existing industry guidelines for the prevention of estrogen-positive breast cancer2,3
