# Physical and clinical results of a radiation bra in patients treated with total skin electron beam therapy

## TL;DR

A radiation bra improves dose delivery to the inframammary folds in women with large breasts undergoing total skin electron beam therapy.

## Contribution

The radiation bra enables adequate dose coverage of shaded areas without additional local irradiation.

## Key findings

- The median inframammary dose was 89% of the prescription dose with the radiation bra.
- Without the bra, the median dose was only 4% of the prescription dose.
- The radiation bra effectively treats shaded areas in patients with pendulous breasts.

## Abstract

Total skin electron beam therapy (TSEBT) in female patients with large or pendulous breasts is usually associated with shaded inframammary folds. In this analysis, 18 patients with cutaneous malignancy and pendulous breasts were irradiated with a radiation bra and five patients received TSEBT without bra. All patients had moderate or severe sagging of the breasts. The median inframammary dose in the radiation bra group was 89% of the prescription dose versus 4% in the group without bra. The usage of the radiation bra enables an adequate radiation dose for the inframammary folds during TSEBT with no additional local irradiation.
