A PILOT STUDY OF DIFFUSION WEIGHTED MRI TO ASSESS ESOPHAGEAL TUMOR RESONSE TO NEOADJUVANT CHEMORADIATION...
Esophageal CancerThe purpose of this research study will be to determine the sensitivity and specificity of dwMRI metrics to assess tumor response following neoadjuvant chemoradiation in esophageal cancer. This pilot study will generate the preliminary data needed for the design of a statistically-justified trial that would investigate dwMRI as an integral biomarker to stratify patients for escalated therapy to improve outcomes. We hope to develop dwMRI as a predictive clinical tool for a personalized treatment model that can identify patients who may be candidates for organ-preservation or treatment intensification to improve outcomes in esophageal cancer.

Outcomes After Esophageal Cancer Surgery
Esophageal NeoplasmEsophageal DiseaseBackground Esophageal carcinoma is the sixth leading cause of cancer -related mortality and the eighth most common cancer worldwide The incidence is increasing rapidly The overall 5-year survival ranges from 15% to 25% in the literature and poor outcomes are related to diagnosis at advanced stages. Surgery used to be the cornerstone of treatment of resectable esophageal cancer, but treatment of esophageal carcinoma remains challenging and need to be considered through a multimodal approach. However the modalities and the impact of this multimodal approach at a national level are unknown Primary objective: To identify predictors of recurrence after esophageal cancer surgery Secondary objectives : 5-year recurrence free survival 5-year overall survival Predictors of postoperative mortality and morbidity after surgery Impact of pCR on recurrence and survival Impact of neoadjuvant treatments on recurrence and survival Impact of patient preconditioning (such as nutritional support, esophageal prosthesis, mini-invasive approach…) on outcomes Methodology : European French-speaking retrospective multicentric study Inclusion criteria: All consecutive patients operated on, for a histologically proven carcinoma of the esophagus, the oesophago-gastric junction (Siewert type I and II), in surgical investigator centers between January 2000 and December 2010 Exclusion criteria: Siewert III type carcinoma of the oesophago-gastric junction , non surgical treatment of esophageal carcinoma Planned study period: The data will be collected over a 11-year period from January 2000 to December 2010. Follow up will be ascertained in May 2013.
Esophageal Cancer Genetics Studies
Esophageal CancerGastric (Cardia1 moreThe overall goal of this project is to understand the role of genetics in the etiology and prevention of upper gastrointestinal cancer, primarily esophageal cancer, but also cancers of the gastric cardia and body. Esophageal cancer is the second most common cause of cancer death in China and the seventh most common cause of cancer death worldwide. Evidence suggests that genetic factors may play an important role in the etiology of this malignancy, and identification of esophageal cancer susceptibility genes may allow screening of populations to identify persons at particularly high risk, who could then be targeted for prevention strategies (e.g., chemoprevention or early detection). There are several lines of evidence supporting the idea that there is genetic susceptibility for esophageal cancer in high-risk Chinese populations, including an association of positive family history with increased risk, evidence of familial aggregation of cases, and segregation analyses suggesting Mendelian inheritance in high-risk families. Several different but complementary approaches will be used to identify esophageal cancer susceptibility genes. (Because of etiologic similarities and for logistic reasons, parallel efforts will be made with gastric cardia and body cancers.) First, a tumor/non-tumor study will be conducted in which a biological specimen bank consisting of samples (tumor, non-tumor, venous blood, finger stick blood, and buccal cells) from several hundred cases of esophageal, gastric cardia, and gastric body cancers will be developed in Taiyuan that can be used for the identification of esophageal (as well as gastric cardia and body) cancer susceptibility genes and potential early genetic markers of these cancers. High-density genome-wide scans with microsatellite markers will be used in a limited number of cases to identify potential hot spots followed by further testing of these hot spots and other candidate markers in additional tumor/non-tumor samples. Premalignant morphologic lesions will also be examined. Second, blood samples for DNA will be collected from approximately 100 healthy individuals from high-risk (Yangcheng County) and low-risk (Beijing) areas to examine potential population differences in polymorphisms for selected genomic markers. Third, a large case-control study with cancers of the esophagus, cardia, and body of stomach will be conducted to evaluate polymorphisms in the candidate markers identified in other components of this project, and to evaluate gene-environment interactions. Finally, a family study will be conducted to evaluate linkage of candidate markers with cancer in families having 2 or more cases with cancers of the esophagus, cardia, and/or body of stomach.
Venous Thromboembolism and Bleeding Risk in Patients With Esophageal Cancer
Venous ThromboembolismEsophagus Cancer2 moreThis study aims to assess the 6- and 12-month venous thromboembolism (VTE) and bleeding incidence from the start of cancer diagnosis in a retrospective cohort of patients with esophageal cancer. Additionally, the predictive value of the Khorana score and several other VTE and bleeding prediction scores and risk factors will be evaluated.

Neoadjuvant Therapy for Esophageal Cancer and Cardiopulmonary Physiology
Esophageal CancerRadiation Pneumonitis9 moreAlthough recent global trends indicate reduced postoperative mortality after esophagectomy, major morbidity, in particular pulmonary, remains high, with considerable health and economic costs. In a recent modern international collaborative series of 2704 patients from high-volume centers, with an approximate equal mix of open and minimally invasive approaches, respiratory complications were evident in 28% of patients, pneumonia in 15%, and respiratory failure in 7%.1 In other series, respiratory failure is reported in up to 15% of patients and is the most common cause of mortality. Prediction of risk and prevention of respiratory morbidity is therefore of considerable importance, and in this context baseline assessment of respiratory physiology compliments clinical assessment, history and enhanced recovery pathways representing key elements of current patient management. In this study, which will include all prospective patients with locally advanced esophageal cancer treated at a National Center, pulmonary function will be systematically measured before and after neoadjuvant therapy. The investigators seek to evaluate the incidence of radiation induced lung injury (RILI), as well as subclinical changes in pulmonary physiology that may be linked to postoperative complications, and quality-of-life in survivorship, and to compare cohorts who received radiation therapy or chemotherapy alone, preoperatively.
