Comparative Effectiveness of Proton Therapy Versus Photon Therapy as Part of Concurrent Chemoradiotherapy for Locally Advanced Prostate Cancer
The use of concurrent chemoradiotherapies is a standard curative treatment for many cancers but is associated with substantial morbidity including hospitalizations during treatment. We conducted a study to assess whether proton therapy in the setting of concurrent chemoradiotherpy is associated with fewer 90-day unplanned hospitalizations or other adverse events and similar disease-free and overall survival compared to photon chemoradiotherapy. This was a retrospective non-randomized comparative effectiveness study.
We found that proton chemoradiotherapy was associated a nearly two-thirds reduction in unplanned hospitalizations with similar disease-free and overall survival.
