Executive summary

This MD Anderson study published in the Green Journal retrospectively compares patients with oropharyngeal cancer (OPC) who received IMRT (n = 429) and IMPT (n = 103).

With a median follow-up time of 36.2 months, the study reported that the moderate-severe xerostomia was less common in the IMPT group than in the IMRT group at 18-24 months (6% vs. 20%; p = 0.025) and 24-36 months (6% vs. 20%; p = 0.01).
