This study by Schäfer and colleagues supports results of earlier and smaller studies showing promising quality of life results following accelerated partial breast irradiation (APBI) using multicatheter brachytherapy, according to Reshma Jagsi, MD.
“The results suggest that for quality of life, multicatheter brachytherapy-based APBI does not adversely affect outcomes, compared with whole breast irradiation,” Dr. Jagsi wrote in an editorial accompanying the article.
Dr. Jagsi highlighted “modest but significant” differences favoring APBI for early breast symptoms, both right after treatment and at 3-month follow-up. Likewise, there were slight improvements in fatigue, emotional functioning, and financial difficulties for APBI-treated patients at both of those time points.
In previous trials, APBI using external radiation beam techniques has likewise shown favorable and promising quality of life outcomes.
There are now eagerly anticipated studies of APBI delivered primarily using external beam techniques that have included rigorous collection of quality of life outcomes, Dr. Jagsi added.
Those trials, which include RAPID and RTOG 0413/NSABP B39, will provide additional evidence to consider alongside those of the trial reported by Schäfer and colleagues on behalf of the Groupe Européen de Curiethérapie of European Society for Radiotherapy and Oncology (GEC-ESTRO).
“Together with the results from the GEC-ESTRO trial, results from these trials will be meaningful to the many tens of thousands of women who undergo breast-conserving surgery and adjuvant radiotherapy each year,” Dr. Jagsi wrote.
