Allegheny Health Network (AHN) today announced the recruitment of breast surgical oncologist Angela J. Keleher, MD to serve as Director of its Division of Breast Surgery

At AHN Dr. Keleher will lead a team of experienced breast surgeons and patient navigators who collaborate with radiologists, oncologists, nurses and other medical professionals to treat thousands of patients every year at locations throughout the greater Pittsburgh region. The program offers patients access to the complete spectrum of advanced treatments for breast disease, including immunotherapy, targeted drug therapies and image guided radiation therapy, along with cutting-edge diagnostic techniques and a surgical options to suit every patient.

“Dr. Keleher is a highly accomplished and talented cancer specialist, and we are thrilled to welcome her back to our organization in this important new leadership role,” said Ngoc Thai, MD, PhD, Chair of AHN’s Department of Surgery.”

Dr. Keleher joins AHN from the Dyson Breast Center in Poughkeepsie, NY, where she served as director and oversaw a $4.2 million renovation and expansion project that transformed the program into an innovative, multi-disciplinary and patient-centered care model for patients. In her 10 years at Dyson, Dr. Keleher helped establish the Breast Center as a leading comprehensive resource that provides patients with every possible diagnostic and therapeutic option, from biopsy and surgery to leading-edge treatments through clinical trials.

Prior to her role at the Dyson Breast Center, Dr. Keleher was Chief of Breast Surgical Oncology at AHN’s West Penn Hospital and assistant professor of surgery at Temple University School of Medicine.

“I’m excited to return to Pittsburgh to lead the breast surgery program at AHN,” Dr. Keleher said. “There is a new energy at AHN, a spirit of growth and innovation that builds on AHN’s long history of groundbreaking breast cancer research and holistic patient care.”

“AHN is committed to the kind of multidisciplinary care that I believe is essential to securing the best outcomes for breast cancer patients. In addition, AHN’s partnership with Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins is opening up a new world of clinical trials and collaboration with our fellow clinicians and researchers,” Dr. Keleher said.

Dr. Keleher completed her clinical breast fellowship at the University of Texas M.D. Anderson Cancer Center in Houston and her general surgery fellowship at West Penn. She earned her medical degree at the University of Illinois at Chicago, is certified by the American Board of Surgery, and is a member of the American Society of Breast Surgeons and the Society of Surgical Oncology. She has been named one of the “Top Docs of the Hudson Valley” every year since 2011.

“Maximizing a patient’s comfort and convenient access to a full spectrum of leading-edge cancer care was central to my vision for the Dyson Breast Center, and will continue to guide my philosophy as leader of AHN’s Division of Breast Surgery,” Dr. Keleher said. “We care for the total patient, and expect to build a life-long relationship that provides them with the best possible chance of a positive long-term outcome.”

AHN and Highmark Health are investing more than $200 million in cancer care, including the construction of a new academic cancer center at Allegheny General Hospital, expansion of AHN’s community-based cancer centers located throughout western Pennsylvania, upgrades of the breast center and cancer center at WPH, as well as a new cancer and imaging center at Forbes Hospital. The investment also includes a strengthening of AHN’s relationship with Johns Hopkins, expanded access to clinical trials, recruitment of new oncologists and continued acquisition of new technologies.

“We are excited to have a physician of Dr. Keleher’s caliber join AHN as leader of our outstanding breast surgery practice, and look forward to seeing her build on AHN’s legacy as a pioneer of practice-changing cancer treatments,” said David Parda, MD, radiation oncologist and chair, AHN Cancer Institute. “Dr. Keleher shares our philosophy of integrated, multidisciplinary collaborative care that is tailored to each patient’s individual needs.”

The AHN Cancer Institute extends world-class expertise to patients through its seven hospitals and more than 50 Cancer Institute clinics across western Pennsylvania, Erie, West Virginia and Ohio. Certified by the American Society of Clinical Oncology’s Quality Oncology Practice Initiative (QOPI), AHN is also the only regional cancer center accredited by the American College of Radiology and the National Accreditation Program for Breast Cancer. AHN hospitals achieved 97 to 98 percent compliance with best practices for cancer care – compared to just 90 percent statewide – as reported by the Commission on Cancer’s Cancer Program Practice Profile Reports.

AHN physicians are leaders in the nation’s largest breast cancer clinical trials group, the National Surgical Adjuvant Breast and Bowel Project. The NSABP’s research changed breast cancer practice, establishing that lumpectomies plus radiation are as effective as mastectomies for cancer treatment, that tamoxifen and raloxifene prevent breast cancer in high risk patients and lower the risk of breast cancer recurrence; established hormonal therapy, chemotherapy, biologic therapy, radiation therapy, sentinel node biopsy, and genomic testing as standards of care that have dramatically improved cancer control and quality of life for breast cancer patients. Innovations by AHN clinicians/researchers also include pioneering the use of Stereotactic Body Radiation Therapy (SBRT) as a potential use for all liver cancers; AHN is further developing this technology, which improves cancer control and decreases the toxicity and length of radiation treatments, for patients with breast and other cancers.
