American Society for Radiation Oncology, Oct. 24-27

The 63rd Annual Meeting of the American Society for Radiation Oncology



The annual meeting of the American Society for Radiation Oncology was held from Oct. 24 to 27 in Chicago and attracted approximately 11,000 participants from around the world, including physicians, oncology nurses, radiation therapists, biologists, physicists, and other cancer researchers. The conference featured educational courses focusing on radiation, surgical, and medical oncology.

In single-institution phase 2 randomized trial, C. Jillian Tsai, M.D., Ph.D., of the Memorial Sloan Kettering Cancer Center in New York City, and colleagues found that the addition of stereotactic body radiotherapy (SBRT) prolongs progression-free survival among patients with metastatic non-small cell lung cancer (NSCLC) with oligoprogression (isolated disease progression).

The authors randomly assigned patients with metastatic NSCLC and patients with metastatic breast cancer who progressed after at least one line of systemic therapy to either continuation of standard of care per physician choice or SBRT followed by standard of care. The researchers found that the addition of SBRT prolonged progression-free survival. The effect was driven entirely by the NSCLC patients, who derived a more than fourfold progression-free survival benefit compared to standard of care alone. The investigators did not observe any difference with the addition of SBRT in the breast cancer group.

“The study is important because, previously, there was no evidence supporting the use of SBRT in the setting of oligoprogression,” Tsai said. “The study will likely make clinicians aware of this treatment option and provide the patients with such information. In addition, this can also lead to a multidisciplinary approach of care in patients with metastatic disease.”

In a prospective trial, Matthew Manning, M.D., of the Cone Health Cancer Center in Greensboro, North Carolina, and colleagues found that the ACCURE (Accountability for Cancer Care through Undoing Racism and Equity) approach is an effective tool that can help eliminate disparities between Black and White patients in treatment and survival rates for early-stage breast cancer and lung cancer.

The authors took a community-based participatory research approach to built transparency and accountability into cancer care. The intervention included four components: a real-time informatics tool to flag missed milestones in care, a specialized nurse navigator to help patients overcome obstacles to care, a physician champion to provide health care teams with race-related feedback on treatment completion, and health equity education training sessions for staff. The researchers found that by implementing the ACCURE approach, system-wide changes can be leveraged to eliminate survival differences in cancer care.

“This study has prompted health systems to build patient tracking systems like the real-time informatics tools and proactively identify and eliminate barriers to cancer treatment,” Manning said.
