MONDAY, Might 2, 2022 (HealthDay Information) — Use of a high-tech radiation most cancers remedy referred to as proton beam therapy (PBT) has elevated total in the US, however Black sufferers are getting it much less typically than white sufferers, two new research present.
Conventional radiation remedy is photon-based, however PBT makes use of protons to ship high-energy beams extra exactly to tumors and reduce damage to surrounding healthy tissue.
PBT will be higher than conventional radiation remedy for tumors with complicated anatomy, tumors surrounded by delicate tissues and childhood cancers, however PBT will be twice as costly, in keeping with the American Most cancers Society.
To evaluate the usage of PBT in the US, researchers analyzed information on practically 6 million sufferers within the Nationwide Most cancers Database. They discovered that total use of PBT for newly identified cancers rose from 0.4% in 2004 to 1.2% in 2018.
Personal protection was the most typical sort of insurance coverage amongst sufferers handled with PBT for beneficial cancers, whereas Medicare was the most typical insurance coverage amongst sufferers handled with PBT for cancers for which the remedy’s efficacy continues to be beneath investigation.
The research additionally discovered that Black sufferers have been much less more likely to be handled with PBT than white sufferers (0.3% vs. 0.5%), particularly for cancers for which PBT is beneficial over conventional radiation remedy.

The research have been printed within the journal JAMA Network Open.
“We discovered that PBT use elevated nationally between 2004 and 2018 for all eligible cancers, particularly for cancers for which PBT is the beneficial radiation remedy,” mentioned Leticia Nogueira, lead creator of each research. She is a senior principal scientist, well being providers analysis, on the American Most cancers Society.
“Particularly regarding, nonetheless, was our findings additionally confirmed racial disparities elevated as availability of PBT elevated within the U.S.,” Nogueira mentioned in a society information launch.
“Our findings, sadly, spotlight the truth that Black sufferers proceed to learn much less from advances in medication like PBT, even with elevated availability of beneficial remedy modalities,” Nogueira mentioned. “Efforts aside from growing the variety of services that present PBT can be wanted to remove these disparities.”
There’s extra on proton beam remedy at Johns Hopkins Medication.
