Rakendu Shukla, 2020 graduateThe UC Davis Department of Radiation Oncology offers a four-year residency training program in clinical radiation oncology. The residency fulfills all requirements of the American Board of Radiology and is fully accredited by the American Medical Association's Accreditation Council for Graduate Medical Education (ACGME). Residents train at the UC Davis Comprehensive Cancer Center and the UC Davis Medical Center based in Sacramento, California. As the only NCI-designated comprehensive cancer center located in the Central Valley region encompassing Sacramento, the UC Davis Comprehensive Cancer Center serves a diverse, high-volume population of various socioeconomic and ethnic backgrounds and captures patients from a large portion of Northern California, Southern Oregon, and Western Nevada.

Our department is committed to creating a work environment where each person is treated with respect, courtesy, and sensitivity. In this regard, the department places an emphasis on adhering to the UC Davis Principles of Community. The UC Davis School of Medicine offers scholarships for underrepresented in medicine (URiM) students from other medical schools interested in an elective experience at one of our residency programs.

The mission of the radiation oncology residency program is to train highly competent academic and private practice radiation oncologists in a multi-disciplinary, collegial setting. We aim to train physicians with broad, clinical expertise in all areas of radiation oncology, including external beam radiation, intracavitary and interstitial brachytherapy, SBRT, intracranial SRS, and transplant preparatory regimens such at total lymphoid and total body irradiation. Residents will undergo rigorous hands-on teaching, including high-volume brachytherapy and other special procedures, formal didactic instruction, with development of lifelong learning skills.

Residents will also gain significant exposure to radiation oncology research, including the design and execution of prospective clinical trials, patient accrual to cooperative group clinical trials, imaging, physics, and laboratory-based research, allowing interested residents to pursue careers as clinician investigators. The mission of UC Davis Health is to serve a diverse racial, ethnic, and socioeconomic community, from urban to rural communities, homeless and wealthy through superior patient care, research, and innovation.

Program Aims

  • Train highly educated residents with the required skill sets to succeed in the academic or private practice setting
  • Provide a culturally and economically diverse training environment, including rural and urban underserved.
  • Provide a strong academic and scholarly environment that enhances the quality of patient care

Program Overview

Residents are assigned to three-month clinical rotations during the course of training. In each rotation, residents practice under the supervision of one and in some cases two site-specific attending physicians in an apprenticeship-like format. These service-focused rotations foster one-on-one teaching and learning. Residents are an essential component of the practice team and work closely with ancillary staff and referring physicians to optimize care. Residents also obtain essential, practical training in physics/dosimetry/treatment during their rotations.

Our faculty of seven radiation oncologists, six medical physicists and three radiobiologists participate in the training and supervision of residents in the classroom, laboratory, and clinic. Residents attend and participate in numerous patient care-related conferences, tumor boards, presentations, and workshops on a weekly basis, typically accompanied by their assigned attending physician.

Clinical Core Didactic Curriculum

The clinical core didactic curriculum has consistently been rated by former and existing residents as one of the strengths of the training program. Lectures are organized into six to eight week didactic blocks focusing on a specific disease-site at a given time. Each of the clinical faculty members serve as moderators on a rotating basis depending on their area of expertise and are overwhelmingly committed to creating an interactive and educationally stimulating environment for trainees. Formal activities include instructional lectures, mock oral boards, case presentations, mortality and morbidity conferences and journal clubs. In 2011, the department began hosting the Cancer Center-wide "high impact" multidisciplinary journal club (held quarterly during lunch on the second Friday of each month) during which recently published literature pertaining to the specified disease site is reviewed with experts from other specialties. Additionally, the curriculum has been recently modified to include lectures on topics such as professionalism, bioethics, statistics, physician wellness, and health economics.
