Sima Porten, MD, MPH

Genitourinary oncologist

Dr. Sima Porten is a genitourinary cancer specialist and part of the urologic oncology team at the UCSF Helen Diller Family Comprehensive Cancer Center. Her clinical interests include the diagnosis and treatment of genitourinary cancer, particularly bladder cancer, upper tract urothelial cancer, kidney cancer and high-risk prostate cancer.

Porten's research focuses mainly on the diagnosis and management of urothelial carcinoma, a cancer involving parts of the kidney, bladder and ureter. In studying the biologic basis of urothelial carcinoma using genomic techniques, she hopes to develop new tests and treatments to bring personalized medicine to patients with bladder cancer.

Porten received her undergraduate, doctoral and public health degrees from Northwestern University. During medical school, she was inducted into the Alpha Omega Alpha Honor Society and also completed a Howard Hughes Medical Institute-National Institutes of Health Research Scholars fellowship. She then completed her urology residency training at UCSF, where she received the Julius R. Krevans Award for Clinical Excellence. During her urologic oncology fellowship at The University of Texas MD Anderson Cancer Center, she was awarded the John Quale Travel Fellowship for her research in bladder cancer.

Porten is an active member of the American Urological Association, American Society of Clinical Oncology, Society of Women in Urology and the Society of Urologic Oncology.
