Multivariate analyses of locoregional recurrences and skin complications after postmastectomy radiotherapy using electrons or photons

Conclusions: Photons are superior to single-portal electrons in patients receiving postmastectomy radiotherapy because of better locoregional control and less skin telangiectasia. In patients in whom the number of positive axillary nodes is >9, more aggressive treatment may be considered for better locoregional control.
