Endobronchial Ultrasonography to Assess and Evaluate Tracheobronchial Tree Invasion in cT4b Esophageal Cancer Patients Treated with Definitive Chemoradiotherapy: Assessment of Resectability.

Background: In cT4b esophageal cancer, accurate assessment of tracheobronchial tree invasion after definitive chemoradiotherapy (dCRT) aids in the selection of patients for whom an oncologic radical esophagectomy can be achieved. The current report aimed to determine the accuracy of endobronchial ultrasound in assessing tumor invasion in the tracheobronchial tree after dCRT in patients with cT4b esophageal cancer.

Methods: Esophageal cancer patients with suspicion of tracheobronchial tree invasion on the diagnostic contrast-enhanced computed tomography (CT) who underwent a staging endobronchial ultrasonography (EBUS) were eligible for inclusion in this study.

A robust semi-automatic delineation workflow using denoised diffusion weighted magnetic resonance imaging for response assessment of patients with esophageal cancer treated with neoadjuvant chemoradiotherapy.

Background And Purpose: Diffusion weighted magnetic resonance imaging (DW-MRI) can be prognostic for response to neoadjuvant chemotherapy (nCRT) in patients with esophageal cancer. However, manual tumor delineation is labor intensive and subjective. Furthermore, noise in DW-MRI images will propagate into the corresponding apparent diffusion coefficient (ADC) signal.

Impact of body composition and physical strength changes during chemoradiotherapy on complications and survival after oesophagectomy.

Background: The aim of this study was to assess body composition and physical strength changes during neoadjuvant chemoradiotherapy (nCRT) and assess their predictive value for (severe) postoperative complications and overall survival in patients who underwent oesophagectomy for oesophageal cancer.

Methods: Consecutive patients who underwent nCRT and oesophagectomy with curative intent in a tertiary referral center were included in the study. Perioperative data were collected in a prospectively maintained database.

The surgical anatomy of a (robot-assisted) minimally invasive transcervical esophagectomy.

Background: Transcervical esophagectomy allows for esophagectomy through transcervical access and bypasses the thoracic cavity, thereby eliminating single lung ventilation. A challenging surgical approach demands thorough understanding of the encountered anatomy. This study aims to provide a comprehensive overview of surgical anatomy encountered during the (robot-assisted) minimally invasive transcervical esophagectomy (RACE and MICE).

Risk Factors for Tumor Positive Resection Margins After Neoadjuvant Chemoradiotherapy for Esophageal Cancer: Results From the Dutch Upper GI Cancer Audit: A Nationwide Population-Based Study.

Objective: To identify risk factors for tumor positive resection margins after neoadjuvant chemoradiotherapy (nCRT) followed by esophagectomy for esophageal cancer.

Summary Background Data: Esophagectomy after nCRT is associated with tumor positive resection margins in 4% to 9% of patients. This study evaluates potential risk factors for positive resection margins after nCRT followed by esophagectomy.
