Background

Dr. Brian Ladle is a pediatric cancer specialist in Baltimore, caring for patients with pediatric sarcoma. 

Dr. Ladle received his undergraduate degree in molecular biology from Brigham Young University. He earned his M.D. and Ph.D. degrees at the Johns Hopkins University School of Medicine. He completed his residency at Cincinnati Children’s Hospital Medical Center and performed a fellowship in pediatric hematology and oncology at Johns Hopkins and the National Institutes of Health. Dr. Ladle joined the Johns Hopkins faculty in 2013.

Dr. Ladle's research focuses on translational immunology, with the goal of developing novel immunotherapies for the treatment of pediatric malignancies. His lab currently focuses on augmenting anti-tumor T cell responses to solid tumors such as osteosarcoma, Ewing sarcoma and rhabdomyosarcoma.

He is a member of the American Association for Cancer Research, the American Society for Pediatric Hematology/Oncology, the American Society of Clinical Oncology and the Children's Oncology Group.

Research & Publications

Research Summary

Dr. Ladle is a practicing pediatric oncologist and translational immunology researcher who has the goal of developing novel immunotherapies for the treatment of pediatric malignancies. His research seeks to understand mechanisms of immune tolerance in pediatric sarcomas and developing successful combination immunotherapies that will successfully treat sarcoma patients. He is working on translational projects combining immunotherapy with chemotherapy, epigenetic modifying agents and innate immune system adjuvants. Dr. Ladle has extensive expertise in immunology techniques – including both mouse and in vitro cell culture, multi-color flow cytometry and molecular techniques.

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
