About Dr. Shamp
Doctor Stephen (Steve) Shamp is a board certified Radiation Oncologist. He received his Bachelor of Science in Electrical Engineering from the University of Notre Dame. He went on to receive his Masters of Science in Electrical Engineering (MSEE) from the University of South Florida with Phi Kappa Phi Honors. He then earned a Masters of Science in Physiology from the University of Cincinnati and was bestowed the Mark A Snowdon Award for outstanding academic achievements. He then obtained his Medical Doctorate (MD) from the University of Cincinnati College of Medicine where he graduated with Alpha Omega Alpha (AOA) honors. He completed his internship in Internal Medicine at Jewish Hospital of Cincinnati. Doctor Shamp then completed his residency training in Radiation Oncology at Case Western University Hospitals Cleveland, where he served as Chief Resident and received the RSNA Roentgen Resident Research Award. He is author and co-primary investigator of CASE1518 clinical trial of external beam radiation therapy combined with immunotherapy in non-small cell lung cancer, and has presented at numerous scientific conferences.
Doctor Shamp is married and lives with his wife and family in St. Petersburg, Florida. In his free time he enjoys traveling, hiking, biking, watersports, scuba diving, astronomy, photography, and working on his Jeep Wrangler.

External Beam Radiation Therapy (EBRT)
External beam radiation uses a sophisticated radiation machine called a linear accelerator to deliver focused beams of radiation. This is an effective treatment for many types of cancer, and can be used alone or in combination with surgery and/or chemotherapy.
Intensity Modulated Radiation Therapy (IMRT)
Intensity Modulated Radiation Therapy (IMRT) is an advanced radiation delivery technique which utilizes multiple radiation beams or arcs to deliver highly conformal radiation to the target area while reducing radiation dose to uninvolved areas to reduce side effects and/or complications.
Image Guided Radiation Therapy (IGRT)
Image Guided Radiaiton Therapy (IGRT) is the use of routine imaging, such as Cone-beam CT (CBCT) or portal imaging. This imaging is typically obtained prior to delivering radiation therapy to improve the the accuracy of the treatment.
Stereotactic Radiosurgery (SRS)
Stereotactic Radiosurgery (SRS) is used for certain tumors of the central nervous system, and involves the pinpoint delivery of high dose radiation therapy. This can involve from one to five total treatments.
Stereotactic Body Radiation Therapy (SBRT)
Stereotactic Body Radiation Therapy (SBRT) involves delivering between one to five doses of high dose radiation therapy with extreme accuracy. This is commonly used for Stage I lung cancer, as well as certain other cancers.
Brachytherapy is the delivery of sealed radioactive sources directly inside or next to the area requiring treatment. I offer both high dose rate (HDR) and low dose rate (LDR) brachytherapy, for the treatment of certain prostate, cervical, endometrial, and skin cancers.
