Dr. Phuoc T. Tran is an associate professor of radiation oncology and molecular radiation sciences, oncology and urology at the Johns Hopkins School of Medicine.

Dr. Tran is the Clinical Director of Radiation Oncology at the Sidney Kimmel Comprehensive Cancer Center and treats patients with cancers of the genitourinary system and uses stereotactic radiation techniques (such as SRS and SBRT/SABR) for the treatment of patients with oligometastatic disease. His research focuses on the improvement of clinical radiotherapy for the treatment of adrenal, bladder, penile, prostate, testicular and urethral cancer as well as patients with oligometastatic disease.

Dr. Tran completed his medical and gradaute training at the Oregon Health & Sciences University in Portland. He conducted a residency in radiation oncology at the Stanford University School of Medicine in 2008 where he was an instructor of radiation oncology before then joining the staff of Johns Hopkins.

Dr. Tran has published more than 60 scholarly works, has received numerous awards for his research, and is a primary investigator on a number of clinical trials.  He is a member and holds leadership positions in the Radiological Society of North America (RSNA) and the American Society for Radiology Oncology (ASTRO), and is board certified in radiation oncology by the American Board of Radiology.

    Research Summary

    Dr. Tran’s research focuses on the improvement of clinical radiotherapy for the treatment of adrenal, bladder, penile, prostate, testicular and urethral cancer. To learn how tumors grow and why some cancers are resistant to treatment, he studies the transitions of epithelial and mesenchymal cellular states in transgenic mouse models.

    Additionally, Dr. Tran is working with colleagues from top-ranked institutions nationwide to establish a National Radiation Oncology Registry. The purpose of the registry is to improve the care of cancer patients by capturing and studying information about cancer treatments and outcomes.

    Dr. Tran and his laboratory focus their studies on the transitions between epithelial and mesenchymal cellular states and the implications of these transitions for tumorigenesis, cancer treatment resistance and radiation-induced fibrosis. Their research utilizes a variety of inducible transgenic mouse models and non-invasive rodent imaging.

    One of these transitions, known as epithelial-mesenchymal transition (EMT), is a conserved developmental program that when inappropriately activated in post-natal life has been associated with organ fibrosis, tumorigenesis and metastasis. A major focus of the laboratory is the use of inducible mouse models to simulate molecularly targeted therapies for malignancies and radiation induced late effects. Another focus of the laboratory is the study of novel targeted agents as tumor selective radiosensitizers to increase the therapeutic ratio of clinical radiotherapy.

    The Tran lab is committed to translating discoveries from the laboratory bench into novel cancer prevention, diagnostic and treatment approaches that can be tested in the clinic.
