PBM was administered three times per week by trained radiation therapists. A historical control cohort treated between 2012 and 2019 was matched 1:1 based on tumor site, concurrent systemic therapy, and prior surgery. The primary objective was to evaluate differences in daily morphine consumption at the end of RT according to the preventive use of thrice-weekly oral PBM in patients receiving curative-intent RT for head and neck cancer.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A total of 280 patients were included: 45% had oral cavity cancers, 43% were treated postoperatively, and 42% received RT without systemic therapy.

No morphine was required in 60% of PBM patients compared with 47% of controls. PBM appeared particularly beneficial in oropharyngeal cancer, in patients receiving definitive RT, and with concurrent treatment.
