Abstract
Analyses have been made of the response of metastatic cervical lymph nodes following neutron therapy, either as part of a randomized trial or in patients treated electively. In the trial patients, the overall regression and local control rates were similar after photons and neutrons. Mobile nodes, less than 3.0 cm, appeared to respond better to neutron therapy, and node masses greater than 3.0 cm had better control after photon therapy. The differences observed however were not statistically significant. There was a highly significant association between the control of the primary tumor and control of nodal disease. No survival advantage for neutrons was observed in association with apparently better control rates in cervical nodes.
