Biomarkers and Functional Imaging in Predicting Response of Esophageal Cancer

Esophageal Cancer

The purpose of this study is to determine whether combination of molecular and biomarkers with functional imaging can predict pathologic response and clinical outcomes in squamous esophageal cancer patients who undergo trimodality therapy which includes neoadjuvant chemoradiotherapy and surgery

Exploration and Verification of DNA Methylolation in Early Screening of Esophageal Cancer

Esophageal Squamous Cell Carcinoma

The aim of this study was to detect the whole genome hydroxymethylation of peripheral blood ct DNA in normal population, patients with p0~pI esophageal squamous cell carcinoma and pII~pIV esophageal squamous cell carcinoma by using DNA methylation detection technology. To compare the differences in genomic methylation levels between different groups, to find out the methylolation site system associated with early esophageal squamous cell carcinoma, and to verify the genes related to esophageal squamous cell carcinoma by ctDNA methylolation. Application of basicization in early screening of esophageal squamous cell carcinoma.

Feasibility and Safety of Using Nasal High Flow Oxygen Postoperatively to Reduce Respiratory Complications...

Cancer of the Esophagus

The use of nasal high flow in patients undergoing oesophagectomy is a novel technique that has not been previously studied. Nasal high flow will be delivered postoperatively to patients undergoing oesophagectomy in a tertiary cancer referral centre. This single-centre cohort study will evaluate the safety of using nasal high flow in oesophagectomy patients. Physiological parameters, adverse events and clinical outcome will be recorded in consecutive patients undergoing oesophagogastric surgery. This study will challenge the hypothesis that the use of nasal high-flow will lower the rates of breathing complications such as pneumonia thereby reducing the demands on intensive care, shortening hospital stay and improving patient quality of life. The results will inform the design of a larger multicentre clinical trial comparing nasal high flow to conventional methods by facilitating sample size calculation.

Preoperative Image-guided Identification of Response to Neoadjuvant Chemoradiotherapy in Esophageal...

Esophageal CancerEsophageal Adenocarcinoma2 more

Rationale: For locally advanced esophageal cancer the standard treatment consists of 5 weeks of neoadjuvant chemoradiotherapy (nCRT) followed by surgery. Surgery is currently performed independent of the response to nCRT and is associated with substantial morbidity. Prior knowledge of the eventual response to nCRT would greatly impact on the optimal care for many esophageal cancer patients for two imperative reasons: Firstly, it is argued that patients who achieved a pathologic complete response (pCR, 29%) may not have benefitted from surgery. Consequently, proper identification of pathological complete responders prior to surgery could yield an organ-preserving regimen avoiding unnecessary toxicity. Secondly, non-responders are exposed to the side effects of nCRT without showing any tumor regression. Early identification of the non-responders during nCRT would be beneficial for this group as ineffective therapy could be stopped, and for who altered treatment strategies could be explored. Objective: To develop a multimodal model that predicts the probability of pathologic complete response to nCRT in esophageal cancer, by integrating diffusion weighted magnetic resonance imaging (DW-MRI) and dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) in conjunction with combined 18F-fluorodeoxyglucose positron emission tomography and computed tomography (18F-FDG PET-CT) scans acquired prior to, during and after administration of nCRT. Study design: Multi-center observational study Study population: Patients (>18 years) with potentially resectable locally advanced squamous cell- or adenocarcinoma of the esophagus or gastroesophageal junction, receiving nCRT prior to surgery. Intervention: In addition to the standard diagnostic work-up for esophageal cancer that includes a 18F-FDG PET-CT scan at diagnosis and after nCRT, one 18F-FDG PET-CT scans will be performed during nCRT, as well as three MRI scans (before, during and after nCRT) within fixed time intervals. Furthermore, after response imaging after nCRT has been performed, but prior to surgery, patients will undergo (on an opt-out basis) an endoscopy and/or endoscopic ultrasonography (EUS) with biopsies of the primary tumor site, other suspected lesions and suspected lymph nodes. Furthermore, blood samples will be collected at three time points. Main study parameters/endpoints: An accurate multimodal prediction model for the patients' individual probability of pathologic complete response after nCRT, based on the quantitative parameters derived from a longitudinal series of DW-MRI, DCE-MRI and 18F-FDG PET-CT datasets.

Health and Employment After Gastro Intestinal Surgery - HEAGIS2

Esophageal NeoplasmsGastric Neoplasm1 more

By using the M.A.D.I.T. methodology and the Dialogics science, SALVO Project aims to develop operational guidelines to support oncological target patients in the resumption of their daily post-operative activities. The research will implement an instrument for the purpose of measuring the health need of participants who are admitted to the surgical ward. Therefore, targeted interventions will be implemented with participants, and efficacy will be evaluated in order to define treatment guidelines. The principal aim of this study is to create a validated and replicable intervention model for supporting patients who undergone surgery for esophageal and gastro intestinal cancer.

Development of a Clinical Decision Support System With Artificial Intelligence for Cancer Care

Gastric CancerEsophageal Cancer1 more

Clinical Decision Support Systems (CDSSs) to augment clinical care and decision making. These are platforms which aim to improve healthcare delivery by enhancing medical decisions with targeted clinical knowledge, patient information, and other health information. In view of the benefit of developing a CDSS, we sought to develop an alternative CDSS for oncologic therapy selection through a partnership with Ping An Technology (Shenzhen, China), beginning with gastric and oesophagal cancer. This would be done in a piecemeal fashion, with the prototype platform utilizing only international guidelines and high-quality published evidence from journals to arrive at case-specific treatment recommendations. This platform would then be evaluated by comparing its recommendations with that from the multidisciplinary tumour boards of several tertiary care institutions to determine the concordance rate.

PLA for HCC and Esophageal ca Serum

Hepatocellular CarcinomaEsophageal Cancer

The primary goal of this study is to quantify the biomarkers of pre-radiation therapy(RT), during-RT, and post-RT serum samples from hepatocellular carcinoma (HCC) and esophageal cancer patients undergoing definitive or neoadjuvant RT, and to correlate them with tumor response, patterns of failure, survival outcome, and RT-related lung or liver toxicity. The secondary goal of this study is to set up the PLA platform in our institute for future biomarker test.
