‘Eye-Popping’ pCR Rate With SABR Alone in Early Lung Cancer

Excerpt:

“Stereotactic ablative radiotherapy (SABR) yielded a surprisingly low pathologic complete response (pCR) rate in a phase II trial of operable, early-stage lung cancer patients, raising questions about SABR alone in this setting.

“In the first study to examine neoadjuvant SABR prior to surgery in non-small cell lung cancer (NSCLC), SABR yielded a 60% pCR rate at 10 weeks post-radiation (95% CI 44%-76%), a rate far lower than hypothesized when the trial was designed, reported David Palma, MD, PhD, of the London Health Sciences Centre in London, Ontario, Canada, and colleagues, in JAMA Oncology.”
