Program Overview

Program Overview

We offer a fully ACGME-accredited four year advanced training program in radiation oncology.  Residents matching at our program are required to complete a separate ACGME-accredited intern year prior to beginning their radiation oncology training.

This superior academic and clinical training program is equipped with the latest radiotherapy and radiosurgery technology and designed to prepare our residents to become future leaders in the practice of radiation oncology.

Cleveland Clinic is a large tertiary care medical center. Accordingly, there is ample clinical experience for residents in training. Residents are exposed to a variety of malignancies and treatments during their training. The department has 2 CT simulators, along with 6 linear accelerators treating up to 150 patients per day.

Experience in intensity modulated radiation therapy (IMRT), Gamma Knife Radiosurgery, stereotactic body radiotherapy (lung, spine, liver, prostate), permanent prostate seed brachytherapy (~7-8 cases/week), total body irradiation, high dose rate brachytherapy, hyperthermia, radioimmunotherapy, and intraoperative radiation are an integral part of Cleveland Clinic's program.

Residents have the opportunity to gain additional pediatric experience at St. Jude Children's Research Hospital or University of Cincinnati.

Curriculum - Radiation Oncology

During the PGY-2 year, new resident are immersed in introductory physics and radio-biology course work in addition to exposure to the fundamentals of radiation oncology. Areas covered include work-up, treatment planning process, delivery of radiation and follow up of patients receiving radiotherapy.

During the PGY-3 year, the residents are expected to improve their understanding of all aspects of radiation oncology, especially the treatment planning process, and also to develop a research interest for the following year.

During the PGY-4 year, residents are expected to perform clinical or basic science research for up to 10 months under the supervision of an appropriate Cleveland Clinic faculty member. One member of the PGY-4 class is selected by the faculty to serve as Chief Resident.

During the PGY-5 year, the level of responsibility is increased. The year is structured to consolidate clinical skills and the knowledge base acquired during the previous three years.

Teaching Conferences
Resident teaching conferences are held daily between 8 a.m. - 9 a.m. and are staffed by radiation oncology attending physicians and medical physicists. Residents are exempt from clinical duties during these times.

Morning Conference
Case presentation and discussion of a specific disease site, once per week. Residents and staff discuss anatomy, work-up, imaging, treatment options, and field design. Residents are expected to study and a handout is distributed at the conclusion of the meeting.

Chart Rounds
A conference to discuss the set-up, planning, and techniques of radiation delivery.

Physics and Radiation Biology Lectures
Weekly interactive lectures in physics and radiation biology are given by faculty members for residents in the PGY-2 to PGY-4 years.

Journal Club
Bi-monthly meetings to discuss recent articles in the field.

Tumor Board
Regularly scheduled multidisciplinary conferences attended by medical oncology, surgery, and radiation oncology in the areas of lung, breast, CNS, spine, head & neck, gynecology, genitourinary, colorectal, hepatobiliary, pancreatic, sarcoma, and lymphoma.

Visiting Professor Program
Up to four times per year, leaders in radiation oncology are invited to spend a day at Cleveland Clinic. Usually, the invited professor will give a lecture and then spend the morning discussing specific cases or issues in radiation oncology with residents.

Research Opportunities

Resident research activity can begin early at Cleveland Clinic. Although there is a dedicated up to 10 months of research time in the PGY-4 year, many junior residents have oral or poster presentations at national meetings such as ASTRO, ASCO, RSNA, AUA, and SNO.

Cleveland Clinic allows residents to attend a meeting of their choice starting in the PGY-2 year. All residents in their PGY-3, 4, and 5 year typically attend ASTRO.

Additional funding is available within the department for residents who present research at other national meetings.

Renowned cancer researcher, Timothy Chan, MD, PhD, has joined Cleveland Clinic as the Director of the new Center for Immunotherapy and Precision Immuno-Oncology, where he plans to unite researchers in multiple disciplines to advance personalized cancer care and develop novel immune system-based treatments. Residents have the opportunity to work with and learn from Dr. Chan.


  • Vacation: 15 days (3 weeks) per year + variable number of meeting days and institutional holidays.
  • Call Schedule: Home call, one week at a time.
  • Book fund: An individual book fund is available for all residents to purchase texts.
  • Office space: Each resident has personal desk space with a laptop and dual monitors. 
  • Cleveland Clinic iPhone: Each resident will receive a Cleveland Clinic iPhone from start to end of your residency.

There are typically three positions available per year. Cleveland Clinic and the Radiation Oncology Program participate in the Electronic Residency Application Service (ERAS) for the application process and the National Resident Matching Program (NRMP) for the matching of residents to programs.

The internship year is not incorporated into the residency program at CCF. Therefore, applicants who match at Cleveland Clinic for radiation oncology residency must complete a separate intern year in an ACGME-accredited program.

Applications will be reviewed upon completion and selected candidates will be invited for interviews. Candidates selected for interviews will be notified in November and interviews will typically occur on Mondays in January.

Each candidate is provided with an individualized timetable for their interview day (typically Monday). For all candidates, this includes a program overview with the program director at approximately 7:30 a.m., morning conference beginning at 8 a.m., after which applicants interview with various members of the department. Each candidate will meet with 6-9 faculty members on interview day, including the Chairman, the Program Director, and the Chief Medical Physicist.

Applicants interested in learning more about our training program are encouraged to contact Aylin Correa at or by phone at 216.445.4379. With interviews moving to the virtual format, our residents and program representatives will be available for regular office hours to answer questions about the program. If you wish to arrange a meeting, please contact Aylin.

Elective Medical Student Rotations
Fourth year medical students interested in an elective rotation in the Department of Radiation Oncology should contact Aylin Correa regarding availability at or by phone at 216.445.4379.

Further information about medical student elective rotations at Cleveland Clinic, including requirements, eligibility and the application form can be viewed at the Cleveland Clinic Medical Student Elective Website.

Students who perform electives at Cleveland Clinic are often expected to function as independent residents. Responsibilities include evaluation of patients, dictation, and presentation of a morning conference. Both research and clinical electives are available.
