Radiation Oncology Residency: The Clinical Experience

A strong clinical oncology experience is fostered by the one-on-one relationship between staff physicians and residents during their rotations. Teaching is emphasized by radiation oncology case conferences, daily multidisciplinary case conferences with the FCCC departments of surgical oncology, medical oncology, radiology and pathology, a multi-disciplinary research lecture series, and didactic lectures given by faculty, residents, and staff.  Overall, about 6 hours per week are dedicated to resident education.  This clinical and didactic training may be enhanced by off-site clinical elective rotations or translational research in our division of radiation physics or biology with a multitude of opportunities in world class benchtop research at the center.

The department has established a national and international reputation in the treatment of breast, prostate, gastrointestinal, lung, head and neck, and gynecologic malignancies

The department has established a national and international reputation in the treatment of breast, prostate, gastrointestinal, lung, head and neck, and gynecologic malignancies. We are also committed to participation in national cooperative group trials sponsored by the National Surgical Adjuvant Breast and Bowel Project (NSABP), the Radiation Therapy Oncology Group (RTOG), and the Gynecologic Oncology Group (GOG) (collectively, the NRG) and ECOG-ACRIN cooperative groups. Approximately 2,000 consultations and 4,000 follow-up visits are seen by FCCC staff each year. The department has approximately 120 patients under treatment each day.

Patients seen in consultation or under treatment by a staff physician are evaluated initially by the resident. Patients are treated with a variety of radiation modalities and techniques, including intensity modulated radiation therapy (IMRT and VMAT), stereotactic body radiation therapy (SBRT), stereotactic radiosurgery (SRS), brachytherapy via high-dose rate (HDR) implants and CivaSheets, SIR-Sphere microspheres, and pulsed low-dose rate radiotherapy (PLDR). Additional non-radiation modalities employed in the department include high intensity focused ultrasound (HIFU) and tumor treating fields (TTF).


A sample rotation schedule:
PGY-2 GU GYN, breast Lung CNS
PGY-3 H/N Buckingham GYN, breast GI
PGY-4 Research
PGY-5 CHOP Elective H/N GU
Abbreviations: CHOP: Children's Hospital of Philadelphia; CNS: central nervous system; GI: gastrointestinal; GU: genitourinary; H/N: head and neck; PGY: post-graduate year

Typically, residents have eight 3-month rotations within the department during their PGY2-3 years. The PGY-4 year is dedicated to 12 months of basic science or clinical research and administrative chief resident duties. PGY-5 residents have three months set aside for outside rotations in pediatrics and other electives.  Each year, residents take part in the clinical in-service self-assessment examination given by the American College of Radiology.


Residents and attendings hold morning conferences two to three days a week, 8-9 am, to discuss general oncology and radiation oncology topics. Every Thursday morning, residents actively participate in the department’s chart rounds. Residents attend one or more of the daily one-hour clinical multidisciplinary case conferences (tumor boards). Current cases are reviewed and discussed with the surgical and medical oncologists, pathologists and radiologists. The typical tumor board schedule:

Tumor Board Schedule  
Mondays, 5 pm: Gastrointestinal Tumor Board
Tuesdays, 12 pm: Breast Tumor Board
Tuesdays, 4:30 pm: Sarcoma Tumor Board
Wednesdays, 7 am / 5:30 pm (alternating):   Genitourinary Tumor Board
Wednesdays, 7:30 am: Thoracic Tumor Board
Thursdays, 4:30 pm (every third week): Melanoma Tumor Board
Thursdays, 4:30 pm: Gynecological Tumor Board
Fridays, 8 am: Head and Neck Tumor Board

The radiation department holds regular journal club and morbidity/mortality.

Residents are on-call by long-range beeper with an attending for a one-week period approximately every eight weeks. While on-call, the resident is responsible for after-hours patient calls (first triaged by the hospital nursing coordinator) and emergency consultations and treatments.

Clinical Attending Physicians

The clinical division of our department consists of eight radiation oncologists with site-specific clinical and research responsibilities. The resident will spend one or more three-month rotations over a four-year period working on a one-to-one basis with each staff member.
