Definitive Chemoradiotherapy and Cetuximab in the Treatment of Locally Advanced Esophageal Cancer...

Esophageal Neoplasm

In patients with esophageal cancer, treatment with curative intent can be given to medically fit patients without distant metastases. It may consist of chemoradiotherapy or surgery alone or in combination. Surgery in combination with chemotherapy is another option. For patients who are not medically fit for surgery or with unresectable invasion in adjacent structures the only alternative with curative intent is, with current knowledge, definitive chemoradiotherapy. In the current study the investigators aim to improve prognosis for patients not suitable for surgery. Patients receive treatment with conventional chemoradiotherapy (oxaliplatin, fluorouracil and radiotherapy) with the addition of a more recently developed drug, an antibody called cetuximab.

Neoadjuvant Chemotherapy Compared With Surgery for Esophageal Carcinoma

Esophagus Cancer

Most ESCC received NAC in China without supportive evidence from local RCTs. The negative conclusion about NAC originated from Western countries in the 1990s. Whether two-field extensive mediastinal lymphadenectomy and paclitaxel/platinum-based chemotherapy results in better survival should be determined. As the highest ESCC incidence area worldwid, we tried to analyze this top with big data by using a single-center case-control retrospective PMS study. Paclitaxel- and platinum-based NAC combined with two-field of the extensive mediastinal lymphadenectomy might provide better survival benefits than primary esophagectomy for stage II/III SCC.

Pre-operative MRI of Esophagus Cancer

Esophagus CancerDiagnoses Disease

The role of MRI in the management of esophageal cancer remains unclear and poorly studied. Recent technical advances suggest that MRI may become a powerful technique for the initial assessment of esophageal cancer, but also for the evaluation of response to neo-adjuvant treatment before surgery. This imaging study will be performed prospectively and consecutively in 60 patients included over a 18-month period in patients wîth newly diagnosed esophageal cancer. The aim of this study is to assess the accuracy of MRI to visualize esophageal tumors, to assess tumor burden and potential contact with adjacent structures as well as associated lymph nodes. If chemotherapy or radio-chemotherapy treatment is indicated before surgery, we will also evaluate whether MRI helps us to better evaluate the response to this treatment in comparison to PET-scan or echo. endoscopy which are the examinations currently performed to evaluate the effectiveness of these treatments. The images of the MRI exams will be interpreted by 1 expert radiologist with no knowledge of the other imaging modalities and transmitted to the doctors in charge for possible consideration for the treatment. Patients will then be followed for one year according to clinical management standards to study the data on treatment complications and cancer progression at one year. The main risk is the administration of a gadolinium chelate-based MRI contrast product used routinely. There is also a risk that the results of the MRI may influence the treatment initially planned for example by canceling a surgical procedure.

Detection of (Sub)Clinical Toxicity in Irradiated vs. Non-irradiated Surgically Treated Esophageal...

Thoracic Tumor

Rationale: Radiation-induced cardiac and pulmonary toxicity after treatment for intra-thoracic tumors is a clinically relevant problem, which may jeopardize the benefit of (neo-adjuvant) (chemo) radiotherapy. Although cure rates are rising since the introduction of neo-adjuvant chemoradiation (neo-CRT) as current standard treatment for esophageal cancer (EC), recent studies showed that there is a substantial risk of non-cancer treatment-related death in these patients. Furthermore, this risk is underestimated as the cause of death of many patients remains unknown, since the distinction between tumor related and non-cancer related death can be difficult. Cardiac and pulmonary toxicity and its interaction as seen in pre-clinical studies might explain for these unknown deaths as suggested in several clinical studies. Clinical imaging studies performed shortly after treatment showed changes in different cardiac function parameters, all related to radiation dose parameters. Systematic imaging studies analysing subclinical toxicities at longer follow up have never been performed, most probably because of poor survival rates. However, identification of the magnitude of (subclinical) cardiopulmonary toxicity, by performing several cardiopulmonary function tests, is essential in this patient group as this toxicity is most likely the cause of the increased mortality after thoracic radiotherapy. For future perspectives, these results can be used to select the best diagnostic methods for a prospective cohort study to develop prediction tools for cardiopulmonary toxicity.. Objective: The main objective of this study is to determine the most suitable diagnostic test to identify cardiopulmonary (dys)function in EC survivors treated with neo-CRT followed by surgical resection. Furthermore, we want to estimate the difference in cardiopulmonary (dys)function in EC survivors treated with neo-CRT followed by surgical resection compared to EC survivors who were treated with surgical resection alone. Study design: Cross-sectional pilot study Study population: 40 EC patients who were treated with curative intent by esophageal resection with or without neo-CRT Intervention (if applicable): Not applicable. Main study parameters/endpoints: As this is an exploratory pilot study to determine the most suitable diagnostic tests for future studies, there will be several endpoints related to (sub)clinical cardiopulmonary dysfunction. Signs of myocardial ischemia, systolic or diastolic dysfunction, rhythm and valve disorders, pericardial effusion and fibrosis, myocardial fibrosis, focal wall motion disorders and coronary calcifications will be analyzed. The cardiopulmonary (dys)function in EC survivors treated with neo-CRT followed by surgical resection will be compared to cardiopulmonary (dys)function in EC survivors treated with surgical resection alone. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Several tests will be performed at one time point, 5-10 years after given treatment. If the findings of the test indicate cardiovascular complications, the patient will be referred to the cardiologist for further analysis and/or preventive measures. As one of the tests, cardiac MRI, including gadolinium (Dotarem 0.2 mmol/kg) enhancement will be performed. Potential side effects of gadolinium include brief headache, nausea (feeling sick) and dizziness for a brief time following the injection. Allergic reactions are rare. Furthermore, a cardiac CT scan will be performed with a total radiation exposure of 0.6 mSv (less than a third of the annual background radiation dose), the risks will be minimal.

TreatmENT of AnastomotiC Leakage After Esophagectomy

Esophageal CancerEsophageal Neoplasms

Rationale: Anastomotic leakage (0% - 30%) is a severe complication after esophagectomy with mortality rates approximately ranging from 2% - 12%. In addition, it is associated with a prolonged ICU treatment and hospital stay. Anastomotic leakage severity is currently graded according to how it is treated (grade I: conservative treatment, grade II endoscopic or radiologic intervention and grade III surgical intervention). However, this scoring system cannot be used to guide decision making when anastomotic leakage is diagnosed in a clinical setting. Factors that may influence the severity of the anastomotic leakage are (amongst others) location of the anastomosis, estimated surface of the defect, estimated circumference of the defect, extent of contamination, degree of sepsis and time from diagnosis until therapy. However, little is known about to what extent these and other factors contribute to anastomotic leakage severity. In addition, there is a paucity of data on what leakage characteristics dictate the success of a specific treatment. Primary study objectives To investigate what factors contribute to anastomotic leakage severity and to compose an evidence based anastomotic leakage severity score. To investigate what anastomotic leakage characteristics are associated with success of different anastomotic leakage treatments and to compare the effectiveness of different initial anastomotic leakage treatments for leakages classified according to severity and leakage characteristics. Study design: International multicenter retrospective cohort study. Study population: Adult patients with anastomotic leakage after esophagectomy and gastric conduit reconstruction for esophageal cancer. Cohort size: 1000-2000 patients with anastomotic leakage after esophagectomy for cancer. Primary outcome parameter: 90 day mortality. Secondary outcome parameters: in-hospital mortality, 30-day mortality, 180-day mortality, comprehensive complications index, total number of reinterventions, hospital and ICU length of stay, hospital related costs.

Cancer of StomachCancer of Esophagus

Objective. The objective of the study is to verify and validate the data collected in the Spanish EURECCA (EUropean REgistry of Cancer CAre) Esophagogastric Cancer Registry between January 2014 and December 2017 through an audit process. It is also intended to describe the initiation and implementation of this Registry as well as its early outcomes. Methods. An audit of registered cases (esophageal, esophagogastric junction and gastric cancer resectable patients undergoing surgery) from 01/01/2014 to 12/31/2017 and a descriptive analysis of these data will be performed. Expected results. The study could show that the Spanish EURECCA Esophagogastric Cancer Registry is a reliable source of information, valid for carrying out specific and exhaustive analysis that may lead to high quality publications in indexed journals. It is also expected to generate a high impact based on the large number of cases included in the Registry, favoring new research projects. Relevance. The standardization of the data collection is essential to compare outcomes between different centers, regions and countries. This study will allows us to verify the integrity of the collected data as well as its accuracy, a critical aspect to gain credibility for future studies using the Registry data.
