Alternative forms of radiation therapy are being employed in clinical trials.
A randomized trial from the RTOG reported improved local control and survival with mixed-beam (neutron/photon) radiation therapy compared with standard photon radiation therapy.[55]

A subsequent randomized study from the same group compared fast-neutron radiation therapy with standard photon radiation therapy. Local-regional control was improved with neutron treatment, but no difference in OS was seen, although follow-up was shorter in this trial. Fewer complications were seen with the use of a multileaf collimator.[56]
