Diaphragm Based Position Verification to Improve Daily Target Dose Coverage in Proton and Photon Radiotherapy Treatment of Distal Esophageal Cancer

In modern conformal radiotherapy of distal esophageal cancer, target coverage can be affected by variations in the diaphragm position. We investigated if daily position verification (PV) extended by a diaphragm position correction would optimize target dose coverage for esophageal cancer treatment.

This study aimed to investigate the effect of thalidomide combined with pacilitaxel plus cisplatin (TP) chemotherapy on serum vascular endothelial growth factor (VEGF) and neuropilin-1 (NRP-1) levels in advanced esophageal cancer patients.METHOD: A total of 133 patients with advanced esophageal cancer receiving treatment in Danzhou People's Hospital from February 2017 to July 2019 were recruited and divided into a control group (CG, n = 53) and a study group (SG, n = 80) randomly. Patients in the CG (53 cases) were treated with TP chemotherapy, and patients in the SG (80 cases) were treated with thalidomide on the basis ab...

ConclusionsOur analysis did not demonstrate an association between radiation dose to gastric substructures and anastomotic complications. However, it showed an association between esophagectomy with cervical anastomosis and anastomotic complications. Patients with distal/gastroesophageal junction tumors who undergo esophagectomy with cervical anastomosis have higher rates of anastomotic complications unrelated to radiation to gastric substructures.

Conclusions EBUS and US-FNA are effective means of sampling clinically indeterminate nonregional lymph nodes, and can significantly impact prognosis, and management. Further investigations in this context are of value in this cohort and should be pursued. Nonregional clinically indeterminate lymph nodes represent a diagnostic dilemma in oesophageal cancer staging. Additional investigations in the form of endobronchial ultrasound are effective at providing additional staging information, and can substantially influence patient care.

ConclusionsThe study presents nomograms incorporating independent clinical risk factors and radiomic signature to predict the prognosis of MEF. This prognostic classification system has the potential to guide therapeutic decisions for patients with malignant esophageal fistulas.

ConclusionsNon-esophagectomy, including a variety of non-invasive procedures, is a safe and available option for patients with T1a stage esophageal cancer. For some T1b esophageal cancer patients, esophagectomy cannot be replaced at present due to its diagnostic and therapeutic effect on lymph node metastasis.

ConclusionsCT contrast radiomics is a simple and non-invasive method that shows promise for predicting pathological T stage and tumor length preoperatively in ESCC patients and may aid in the accurate assessments of patients in combination with the existing examinations.

bing Ding Neoadjuvant therapies, primarily chemotherapy and chemoradiotherapy, are able to improve the overall survival (OS) in patients with locally advanced resectable esophageal cancer (EC) based on the results of several randomized clinical trials. The advantage of neoadjuvant therapy is chiefly attributed to the decreased risk of local–regional recurrence and distant metastasis. Thus, it has been recommended as standard treatment for patients with resectable EC. However, several fundamental problems remain. First, the combination of neoadjuvant chemotherapy (nCT), neoadjuvant chemoradiotherapy (nCRT), and su...

group Florence Molinié Guy Launoy Social inequalities are an important prognostic factor in cancer survival, but little is known regarding digestive cancers specifically. We aimed to provide in-depth analysis of the contextual social disparities in net survival of patients with digestive cancer in France, using population-based data and relevant modeling. Digestive cancers (n = 54,507) diagnosed between 2006–2009, collected through the French network of cancer registries, were included (end of follow-up 06/30/2013). Social environment was assessed by the European Deprivation Index. Multidimensional pe...
