Correlation between gastric volume and organs at risk dose in adjuvant radiotherapy for left breast cancer.

Background: The role of the gastric volume on the dose-effect relationship for these organs has not been investigated. The aim of the study was to evaluate the correlation between gastric volume and dose-volume histogram (DVH) parameters of the heart, left lung and stomach during left breast cancer radiotherapy (RT).

Materials And Methods: Ninety-nine left breast cancer patients who got adjuvant radiotherapy were included.

Transcriptomic and proteomic approaches reveal biological basis of intraoperative radiotherapy-treated tumor bed modification in breast cancer patients: A pilot study.

Aim: Intraoperative electron Radiotherapy, herein referred to, as IOeRT is a novel approach in breast cancer (BC) treatment. This study designed to investigate short-term molecular effects of 12Gy as Boost versus 21Gy as Radical dose of IOeRT using high throughput approaches.

Materials And Methods: Six BC patients as a pilot study were treated with IOeRT following two separate strategies, including Boost and Radical doses.
