As Chief of the Division of Infectious Disease in the Department of Medicine at Cancer Treatment Centers of America® (CTCA), Dr. Mashiul Chowdhury knows how important it is to keep patients safe from infections during cancer treatment. And he knows that the only way to do his job is to take his time with each patient, in keeping with the CTCA® approach. “CTCA is a community where everyone is connected, and where the comfort of patients is the priority,” says Dr. Chowdhury.

Dr. Chowdhury earned his medical degree at Dhaka Medical College, in Bangladesh. He was then a postdoctoral research fellow studying biochemistry at Thomas Jefferson University in Philadelphia. In 1994, Dr. Chowdhury became a medical resident and the chief medical resident at Mercy Catholic Medical Center, in Darby, Pennsylvania. In 1988, he began a fellowship in infectious diseases at MCP–Hahnemann University, in Philadelphia.

As an infectious diseases specialist, Dr. Chowdhury has a diverse research background. At Thomas Jefferson University, he studied rheumatology, cell biology, and molecular biology. For the past decade, he has held multiple clinical and academic positions. In 2000, he became attending physician and consultant with the department of infectious diseases at Mercy Catholic Medical Center in Lansdowne, Pennsylvania. He was as associate professor, program director of the infectious disease fellowship, and director of the TravelHealth Center at Drexel University College of Medicine, in Philadelphia. He also served as attending physician of infectious diseases at Hahnemann University Hospital. Dr. Chowdhury joined CTCA in 2006.

Dr. Chowdhury is board certified in infectious diseases and was certified as a diplomat with the American Board of Internal Medicine in 1998. He is a member of the Infectious Disease Society of America, the Society of Healthcare Epidemiology of America, the American Society of Tropical Medicine and Hygiene, the International Society of Travel Medicine, and the American College of Physicians.

He has chaired numerous academic and medical committees during his career, and has lectured and published widely on infectious diseases and the safe use of antibiotics. He has led clinical trials for the treatment of several infectious diseases, and his studies are published in prominent scientific journals. In 2016, he was recognized by the Pennsylvania Hospital Authority with an I Am Patient Safety award, given to health-care workers for their efforts to improve patient safety.

At CTCA, Dr. Chowdhury is focused on preventing and promptly treating infections among people being treated for cancer, because chemotherapy, radiation, and surgery can diminish the body’s natural ability to fight infections. He also educated patients and healthcare professionals at CTCA on how to prevent infections. “When I see my patients smiling in the hallway every day, I feel that I am in the right place,” says Dr. Chowdhury.

Dr. Chowdhury is also an artist. His work has been shown in galleries in Philadelphia and received awards in juried competitions.

Patient ratings
Star ratings and comments are only available for medical, radiation and gynecologic oncologists. Gynecologic surgical offerings are not included at this time due to a different survey tool required to evaluate these services. CTCA uses a validated Press Ganey® survey, which captures patient experience feedback for the primary oncology services of chemotherapy and radiation therapy at our comprehensive care and research centers. Following industry best practice, star ratings and comments are only published for physicians with a minimum of 30 completed patient surveys.
