Background

Dr. Armstrong works primarily in the area of women's malignancies, with a particular emphasis on breast cancer, ovarian cancer and other gynecologic malignancies, and the genetics of breast and ovarian cancer. She directs the medical gynecologic oncology clinical service and oversees therapeutic clinical trials in gynecologic cancers. Dr. Armstrong's clinical focus is on the development of new therapeutic approaches to the treatment of breast cancer and gynecologic malignancies. Particular areas of interest are intraperitoneal therapy in ovarian cancer and targeted biologic therapies. Dr. Armstrong also directs the Kimmel Cancer Center's Breast and Ovarian Cancer Screening Service, a genetic counseling service that focuses on identifying patients at risk for cancer and examination of new strategies for cancer screening and prevention.

Dr. Armstrong has lectured locally, nationally and internationally. She is active in the Gynecologic Oncology Group, serving on the Medical Oncology, Developmental Therapeutics and Phase I GOG committees and as chair of several clinical trials through this group. She is a representative of the Southwest Oncology Group to the Gynecologic Cancer Steering Committee of the National Cancer Institute. Dr. Armstrong also serves as a representative of Johns Hopkins to the National Cooperative Cancer Network serving on the ovarian cancer and breast cancer risk reduction panels. She has participated as a member of the Cancer Working Group for the Office of Research on Women's Health for the National Institutes of Health, as a scientific reviewer for the breast and ovarian cancer research programs of the Department of Defense and the National Cancer Institute, as a reviewer for the NCI Special Emphasis Panel for Insight Awards to Stamp Out Breast Cancer and as a member of the NCI SPORE Program parent committee.

Dr. Armstrong also is co-principal investigator for the NCI National Clinical Trials Network (NCTN) Lead Academic Participating Site (LAPS) at Johns Hopkins, now the major avenue for adult oncology clinical trials in the country. Recent work includes immune checkpoint inhibitor therapy in endometrial cancers with microsatellite instability and PARP inhibition in ovarian cancer.

Research Summary

The overall global research focus of Dr. Armstrong is on the development of new approaches to prevention, early detection and treatment of breast cancer and gynecologic malignancies. Her clinical focus covers three broad categories: treatment of gynecologic cancers, treatment of breast cancer, and genetic risk factors for breast and ovarian cancer with a particular emphasis on early detection and prevention for high risk women. 

Much of Dr. Armstrong's work in treatment of gynecologic malignancies has been done through the Gynecologic Oncology Group. She has served as a member of the Ovarian Cancer, Developmental Therapeutics, Phase I Committee and Medical Oncology Committees for the GOG. Completed studies through the GOG for which Dr. Armstrong has been a Principal Investigator include a phase I study of taxol, cisplatin and topotecan in newly diagnosed ovarian cancer, a phase I study if intraperitoneal paclimer microspheres in ovarian cancer, a randomized phase III study of IV cisplatin and paclitaxel vs. an intensive intraperitoneal approach using these drugs in newly diagnosed ovarian cancer, phase II studies of Bryostatin-1 in ovarian cancer and cervical cancer and a trial of carboplatin and cetuximab in recurrent ovarian cancer. GOG studies ongoing or in development for which Dr. Armstrong is an investigator include a phase III trial of paclitaxel and carboplatin with or without bevacizumab in recurrent platinum sensitive ovarian cancer, a randomized phase II trial of temozolomide with or without the PARP inhibitor ABT-888 in uterine leiomyosarcoma, and a phase I trial of pegylated liposomal doxorubicin and carboplatin with the PARP inhibitor ABD-888 and bevacizumab. 

In addition to work with GOG, Dr. Armstrong has worked at the institutional level on the development of new treatments for gynecologic malignancies. Current clinical trial directions include evaluation of the folate receptor alpha antagonist Farletuzumab in the treatment of both platinum resistant and platinum sensitive ovarian cancer, the use of sequential blockade of the VEGF pathway with the combination of bevacizumab and enzastaurin in gynecologic malignancies and targeting surface lectins with AGS8M4 in ovarian cancer. Ongoing areas of potential translational laboratory research include targeting Notch in ovarian cancer and identification and characterization of ovarian cancer stem cells.

Dr. Armstrong's work with breast and ovarian cancer patients has led to an increasing interest in identifying patients at increased risk of these diseases. Dr. Armstrong serves as director of the Breast and Ovarian Surveillance Service. This service provides genetic counseling and risk assessment for patients at an increased risk of developing these diseases. Ongoing trials through the high risk clinic evaluate screening, early detection and prevention. These studies include an ovarian cancer screening study (ROCA study), characterization of benign breast disease in women at increased risk for breast cancer and an evaluation of BRCA polymorphisms and clinical outcome in ovarian cancer.
