# Modified total skin electron treatment for a paraplegic patient

## TL;DR

A modified version of Total Skin Electron Therapy was developed to treat a paraplegic patient with mycosis fungoides.

## Contribution

A modified TSET approach was introduced to accommodate patients who cannot stand upright.

## Key findings

- A ±30% dose uniformity was achieved at the patient's surface using the modified setup.
- The treatment used two 6 MeV dual beams with adjusted isocenter to surface distance.

## Abstract

Total Skin Electron Therapy (TSET) has been a highly effective treatment for mycosis fungoides (MF). However, the standard TSET treatment requires the patient to stand upright in six different positions for an extended time period, which may not be possible for some patients. Herein, is reported a modified TSET is reported to accommodate a paraplegic patient. Two dual beams of 6 MeV, commissioned for the standard TSET, were used for treatment. The patient's treatment surface was maintained within 190–240 cm isocenter to surface distance (ISD) and 100 cm horizontally. In vivo measurement showed that a ± 30% dose uniformity was achieved at the patient's surface.
