Radiation Oncology Los Angeles Medical Center - Scholarly Activity

There are ample opportunities for high impact resident research at Kaiser Permanente. Residents have access to an extensive tumor registry through our large integrated health care system. Each year, there are multiple projects accepted for oral and poster presentations at ASTRO and manuscripts accepted for peer-reviewed publication. Multiple resident-led projects have been selected as “Best of ASTRO” and “ASTRO Science Highlights”. Recent resident presentations and publications are below:
