Saravut J. Weroha, M.D., Ph.D., is a medical oncologist focusing primarily on gynecologic malignancies and phase 1 clinical trials. His specific areas of clinical focus include:

  • Personalized cancer therapy using ovarian cancer patient-derived xenografts (PDXs), also known as Cancer Avatars, to accurately predict response to anti-cancer treatment.
  • Implementing a multidisciplinary approach to cancer care for strategic utilization of anticancer therapies, such as surgery, radiation, ablation, embolization, and chemotherapy.
  • Searching for molecular targeted therapies based on the specific genetic aberrations found within individual tumors by state-of-the-art next-generation sequencing techniques.
  • Selection of clinical trials that fit the patient's tumor type, molecular profile, and goals of care. This requires careful consideration of individual social factors as well as tumor biology.
  • Above all, working closely with patients as a guide to devise a therapeutic plan which is most optimal for the needs of our patients.

Dr. Weroha works to bridge the gap between promising new therapies in the laboratory and ultimately FDA approval of new therapies for patients with cancer.
