# Locally Advanced Cervical Cancer in a Patient with Epidermolysis Bullosa Treated with Concurrent Chemoradiotherapy and Electronic Brachytherapy

## TL;DR

A patient with a rare skin condition and cervical cancer was successfully treated with a combination of radiotherapy, chemotherapy, and electronic brachytherapy without worsening her skin condition.

## Contribution

This is the first report of combined chemoradiotherapy and electronic brachytherapy for cervical cancer in a patient with epidermolysis bullosa.

## Key findings

- The treatment was well-tolerated with no grade 2 or higher adverse events during follow-up.
- Electronic brachytherapy delivered targeted doses without increasing skin toxicity.
- The institutional protocol ensured low doses to organs at risk and reproducibility.

## Abstract

Background and Clinical Significance: The purpose of this report is to investigate the feasibility of combined modality treatment in a case of locally advanced cervical cancer in a patient with inherited epidermolysis bullosa as well as to suggest a protocol for cervical electronic brachytherapy. Case Description: The patient was treated with image-guided external beam radiotherapy and concomitant chemotherapy to a dose of 45 Gy in 25 fractions with a simultaneously integrated boost of 55 Gy in involved lymph nodes. The maximal skin dose was 34.09 Gy. Intracavitary electronic brachytherapy was applied to the uterine cervix in 4 fractions of 7 Gy and contributed no dose to the skin. Discussion: The treatment was tolerated well with no early toxicity. During the 3-month period of follow-up, no adverse events of grade 2 or higher were detected, and no exacerbation of skin lesions was noted. Conclusions: This is the first report of treatment of cervical cancer in a patient with inherited epidermolysis bullosa where combined concurrent chemoradiotherapy and intracavitary electronic brachytherapy demonstrated feasibility and safety. The followed institutional protocol for treatment planning and delivery ensured low doses to organs and risk and reproducibility.
