Impact of Dose to Cardiac Substructures on Survival in Patients With Esophageal Cancer Treated With Radiotherapy or Chemoradiotherapy (SATIATION)

Overview

Treatment of non-operable esophageal cancers is based on radiochemotherapy, or exclusive radiotherapy. The cardiac toxicity of radiotherapy in the treatment of thoracic tumor localizations is well documented, however, more and more studies are calling for the use of dosimetric parameters related to cardiac sub-structures to be integrated into clinical practice, rather than considering the heart as a whole. With this in mind, the aim of this study is to define the parameters, particularly dosimetric ones linked to cardiac sub-structures, influencing survival in patients treated with exclusive radiotherapy or radiochemotherapy for esophageal cancer.

The cardiac toxicity of radiotherapy in the treatment of thoracic tumor localizations is well documented, however, more and more studies are calling for the use of dosimetric parameters related to cardiac sub-structures to be integrated into clinical practice, rather than considering the heart as a whole. Although most of these data have been studied in populations with long-term follow-up, such as breast cancer, cardiac toxicity and the reduced survival it entails are also found in diseases such as esophageal cancer. With this in mind, the aim of this study is to define the parameters, particularly dosimetric ones linked to cardiac sub-structures, influencing survival in patients treated with exclusive radiotherapy or radiochemotherapy for esophageal cancer.
