Thanks, Pete. For the third quarter in a row, we saw strong growth in molecular diagnostics revenue with contributions across our portfolio of tests, including a record quarter for both BRACAnalysis and COLARIS. These results are due to the successful execution of the initiatives associated with our first strategic directive to grow our existing tests and markets. I will provide a brief update on the progress of these initiatives and our PROLARIS test.
Our Oncology segment grew 19% year-over-year in the third quarter. This accelerated growth was due to a 51% growth rate in COLARIS, and a 14% growth rate in BRACAnalysis in the oncology market. Our efforts to grow the Oncology market for BRACAnalysis through the development of the ovarian cancer, carcinoma in situ and triple negative breast cancer indications, again contributed significantly to growth this quarter. As a reminder, these indications increase the addressable oncology market for BRACAnalysis by approximately $200 million to an annual market potential of $650 million.
In total, these indications grew 57% this quarter compared to the third quarter of last year.
We continue to educate physicians on the updated NCCN guidelines for triple negative breast cancer, and as a result, are testing newly diagnosed patients and also reaching patients which have been diagnosed prior to the updated guidelines. We believe the BRACAnalysis oncology market is approximately 45% penetrated and anticipate continued opportunities for future growth.
I would also like to provide an update on our strategy to pilot cancer specialist teams in our Oncology segment. As a reminder, this program added an 8-person colon cancer specialist team to sell COLARIS, COLARIS AP, TheraGuide and OnDose, alongside what became a breast cancer specialist team focused solely on BRACAnalysis.
I am pleased to report that this program is demonstrating strong results. Since the beginning of the program, both the pilot colon cancer and the breast cancer teams have grown revenue at close to twice the rate of the national average, and generated approximately $1.5 million of incremental revenue. This increased focus has allowed these specialist teams to spend more time with the specialty physician groups in mammography centers or GI centers that see large numbers of high-risk patients. We are continuing to monitor the progress of this program and are planning on expanding the program in fiscal 2013.
In the Women's Health segment, we again encountered headwinds of resetting and higher deductibles in the beginning of the calendar year. As a result, Women's Health revenue declined 3% sequentially. But more importantly, compared to the prior year, Women's Health revenue grew 25%. We continued to deliver strong results from our initiatives to grow same-store sales and new territories in addition to our interactive marketing campaign.
In the third quarter, same-store sales grew an impressive 24% year-over-year. The new territory split in the beginning of fiscal 2011 grew 23% year-over-year during the third quarter and the new territory split in the beginning of fiscal 2012 grew 31% year-over-year.
Our interactive media campaign also continues to progress well. During the quarter, we launched a new website called mysupport360. This site is a unique personalized resource for patients and provides information and encouragement about testing for hereditary forms of breast, ovarian, colon and endometrial cancers. The purpose of this website is to provide guidance, education and support through the testing process, thereby empowering people to be proactive about their health and their families.
We also continue to optimize our physician website, myriadpro.com, which has resulted in a 56% increase in revenue directively attributed to these online inquiries.
In total, during the third quarter, we have seen 100% increase in our physician and patient website visits to over 30,000 visits per quarter. While we are happy to report that the utilization environment improved this quarter, these initiatives have been put in place in an effort to grow the Women's Health segment independent of OB/GYN offices.
COLARIS and COLARIS AP continue to gain traction in the field. Revenue from these tests grew 51% during the third quarter, benefiting from both the impact of PMS2 and an increase in overall demand. The impact of PMS2 led to approximately 60% of the growth and the rest came from an increase in demand and market share gains.
In the third quarter, we presented a poster at the American College of Medical Genetics that showed that 14% of mutation carriers were attributed to a mutation in the PMS2 gene. As a result, conversations with payers on PMS2 reimbursement are progressing well with more than 90% of our top payers now reimbursing for our 4 gene test. In addition, we received New York State approval for PMS2 in the third quarter which will provide additional revenue growth in the fourth quarter and beyond.
Now I would like to provide an update on the clinical research program for PROLARIS. During the third quarter, our clinical research and commercialization efforts showed significant progress. PRO003, our second study for the pre-prostatectomy indication was published in the British Journal of Cancer. Additionally, PRO004, our second study for the post-prostatectomy indication conducted in collaboration with UCSF, was presented at ASCO GU and won the Best Poster Award at the EAU Annual Congress and has been submitted for publication to a major journal.
PRO006, the 250 patient Phase IV study being performed in conjunction with a clinical research organization that represents 25% of the community of urologists in United States is enrolling well. The study is designed to document the distribution of PROLARIS scores and the resulting treatment decisions, both of which will be useful for reimbursement discussions.
As of the end of March, more than 180 patients have enrolled in the study, and we expect to complete enrollment during the fourth quarter. We have completed laboratory processing for PRO005, a 340-patient biopsy study conducted in collaboration with Duke University, which is designed to assess biochemical recurrence for patients selecting either radiation or prostatectomy.
For PRO007, we have collected 25% of the biopsy samples which will eventually be correlated to biochemical recurrence.
Lastly, we signed a research collaboration agreement with Intermountain Health Care, covering numerous potential research projects, the first of which will be PRO008, a 200-patient biopsy data set evaluating biochemical recurrence after radical prostatectomy.
In total, after completion of all 9 of these studies, we will have tested PROLARIS on about 3,500 patients.
Our commercialization efforts are also progressing well for PROLARIS. We almost doubled our sales team and now have hired 18 of the 20 field-based personnel focused on PROLARIS. Urologists have been very receptive to utilizing a new diagnostic tool, and we are receiving commercial samples from physicians. Our laboratory has been successful at producing a PROLARIS' results for 95% of biopsy and post-prostatectomy samples, which are much more challenging to work with than blood samples.
Our conversations with payers have also been very positive, both from a clinical utility and a pricing perspective. By the end of the fourth quarter, we expect to have meetings completed and dossier reviews underway or completed with all of our major payers.
In summary, we are very pleased with the performance of the molecular diagnostic business. We have diligently focused on the execution of our first strategic initiative, to grow our existing tests and markets, which led to strong financial results for the third quarter.
We continue to see significant opportunities for growth from our existing products and in the future, from PROLARIS.
I will now turn the call over to Jim.
