Welcome from the Chair/Chief, Division of Radiation Oncology

Dr. Robert Dinniwell








Welcome to the Division of Radiation Oncology within the Department of Oncology at Western University. A central mission of the Division is the provision of exemplary patient care. We are a key provider of cancer care to Southwestern Ontarians and partner programs throughout the province. Together, we strive to ensure best patient care informed by a multi-disciplinary and collaborative practice, and are guided by quality, education, and research.

With a growing incidence, prevalence, and burden of cancer, we are aware of the need to both lead and drive change within our field. Our faculty has led pivotal clinical trials, and facilitated innovation in patient care, education, and training. We are focused on the ongoing development of a learning culture and a spirit of inquiry with an acceptance of change. Research is a core element to our shared success. Indeed, we are actively engaged in the spectrum of research from basic science through to clinical trials that help to guide and inform best patient care. Our residency training program is recognized internationally and focused upon clinical training and an innovative pedagogy to afford a world class experience in research, education, and program administration/physician leadership.

The Division of Radiation Oncology strives to further its commitment to excellence and seeks to position itself as a clinical, educational, and research leader within the Schulich School of Medicine & Dentistry at Western University, and beyond. Our commitment is to establish and maintain a key role as the most trusted provider of patient care, and a respected partner in education and research within Southwestern Ontario and beyond.

Program Structure and Duration 

The Radiation Oncology Residency Program is a five-year program and included the areas listed below:

Radiation Oncology Academic blocks

The program consists of two to three month rotations, during which a trainee will be generally assigned to a radiation oncologist having primary responsibility for treatment in specific organ sites - neuro-oncology, head and neck, thoracic oncology, breast, gynecological, genitourinary oncology, GI tract malignancies, sarcomas, melanomas and other malignancies. During the first year there is also a two to three month rotation through medical oncology at the London Regional Cancer Program. During the first to second year there is a three to four month rotation in internal medicine. Two months are spent in physics and there is up to six months of elective time to include further clinical oncology, pediatric oncology basic research and further experience in radiation oncology. A substantial proportion of the training is done in outpatients areas at the London Regional Cancer Program.

Trainees will be expected to actively participate in clinical rounds, grand rounds, conferences, seminars and journal clubs. Trainees will also be expected to attend a 74-hour program on core oncology knowledge during their training years. There are courses on treatment planning, general oncology, statistics and quality assurance. A monthly journal club is ongoing.

Research Opportunities and Awards

Dr. David PalmaRadiation Oncology Residents are expected to complete at least one research project during their five-year program. Historically, our residents are involved in a number of research projects and publications during their time in the program. This is undoubtedly due to the unparalleled research support offered by Dr. David Palma, Research Director, and the enthusiastic staff at the London Regional Cancer Program (LRCP).

Depending on the individual goals of each resident, Dr. Palma will help facilitate a project that is of interest to the individual resident and ensure that they are supported from planning to publication.
