Dr. Kilgore is an anatomic pathologist who specializes in the diagnosis of breast and gynecological-related diseases. His education and training include a B.S. from the University of Washington in 2004, an M.D. from Jefferson Medical College in 2010, residency in anatomic and clinical pathology at the University of Washington in 2014 and breast and gynecologic pathology fellowship training at the University of Washington in 2015. In addition to his clinical practice, Dr. Kilgore serves as UW acting assistant professor in the Department of Pathology at the University of Washington. His scholarly activity is focused on cancer research primarily in the fields of breast and gynecologic diagnostic pathology. Dr. Kilgore is committed to medical education and actively involved in the teaching of pathology residents and fellows on a daily basis in addition to lecturing in the pathology course at the University of Washington School of Medicine.

Patient Care Philosophy

I believe it is the job a pathologist to not only diagnose disease, but to be able to relay those diagnoses and results to clinicians and patients in a concise and informative report. This requires a carefully thought-out approach which at times necessitates stepping into the role of the treating provider to ensure the pathology report I am generating will result in the appropriate relay of information and treatment of the patient. I feel strongly that the practice of medicine historically has tried to place patients and diagnoses in well-defined boxes to determine treatment, but that biology ultimately decides the outcome of that decision. It is my goal to educate both clinicians and patients through well-crafted reports and interpretations such that it is more clear when a patient does not fit in the classic categories and may warrant different treatment plans. This is what I believe is truly "personalized medicine."

Clinical Interests

Clinical research in breast cancer; ductal carcinoma in situ of the breast; gynecological cancer; pathology resident graduate medical education; process improvement; algorithms and novel approaches to approve efficiency and conveyance of pathology information in diagnostic reports.

Research Interests

Research to determine characteristics of ductal carcinoma in situ (DCIS) of the breast that are likely to progress/recur; immunohistochemical (IHC) markers in DCIS; mismatch repair protein expression in women with endometrial cancer; CD200 IHC expression in neuroendocrine carcinoma; South-East Asian variant alpha thalassemia; HER2 protein expression heterogeneity in breast cancer.
