Dose advantage of abdominal deep inspiratory breath-hold (aDIBH) in postoperative adjuvant radiotherapy for left breast cancer.

Purpose: We explored the dosimetric efficacy of the abdominal deep inspiration breath hold (aDIBH) technique using an audio-guided device in patients with left breast cancer undergoing postoperative adjuvant radiotherapy compared to free breathing (FB).

Methods: A total of 35 patients with early stage left breast cancer underwent two computed tomography simulation scans each with aDIBH and FB after breast-conserving surgery. Treatment planning was optimized using the Pinnacle 9.

Innovation spillover effect of the pilot carbon emission trading policy in China.

In today's society, environmental protection and sustainable development have become the focus of global attention. Carbon emission trading, as an effective means to reduce greenhouse gas emissions, has been adopted by many countries and regions. In China, the launch of pilot policies for carbon emissions trading is of great significance in promoting economic transformation, promoting industrial upgrading and protecting the environment.

Prone position versus supine position in postoperative radiotherapy for breast cancer: A meta-analysis.

Background: This meta-analysis evaluates the difference of sparing organs at risk (OAR) in different position (Prone position and Supine position) with different breathing patterns (Free breathing, FB/Deep inspiration breath hold, DIBH) for breast cancer patients receiving postoperative radiotherapy and provides a useful reference for clinical practice.

Method: The relevant controlled trials of prone position versus supine position in postoperative radiotherapy for breast cancer were retrieved from the sources of PubMed, Cochrane Library, Embase, Web of Science and ClinicalTrails.gov.

Meta-analysis of deep inspiration breath hold (DIBH) versus free breathing (FB) in postoperative radiotherapy for left-side breast cancer.

Objectives: This meta-analysis evaluates the difference in deep inspiration breath hold (DIBH) versus free breathing (FB) for patients receiving postoperative radiotherapy for left breast cancer and provides a useful reference for clinical practice.

Methods: The relevant controlled trials of DIBH versus FB in postoperative radiotherapy for left-side breast cancer were retrieved from the databases of PubMed, Science Direct, Cochrane Library, and Web of Science databases. The principal outcome of interest was heart dose, left anterior descending coronary artery (LADCA) dose, and left lung dose and target coverage.
