Active clinical trials for "Esophageal Neoplasms"

Indocyanine green (ICG) has been recently introduced in clinical practice as a fuorescent tracer. Lymphadenectomy is particularly challenging in esophageal cancer surgery, owing to the complex anatomical drainage.Therefore, the purpose of this study was to explore whether the NIR-ICG imaging system could accurately assess the lymph node markers during radical resection of esophageal cancer.

The incidence of adenocarcinomas of the esophagogastric junction (AEJ) has increased rapidly during the past decades. By the Siewert classification, the AEJ is the tumor center located 5 cm above the anatomic cardia and 5 cm below it, which is divided into three individual subtypes. Complete tumor resection is the primary therapy strategies for tumors of the AEJ. The Japan Clinical Oncology Group 9502 (JCOG 9502) found that transabdominal or transhiatal approach gastrectomy has better survival outcomes compared with left thoracoabdominal approach surgery for Siewert II/III tumors. Transabdominal approach gastrectomy is recommended as the standard treatment strategy for Siewert II/III tumors by the guidelines of the Japanese Gastric Cancer Association (JGCA). However, the length of the proximal resection margin for Siewert-II/III tumors by transabdominal/transhiatal gastrectomy is still controversies. Previous study found that longer than 2cm proximal resection margin had better survival outcome than less than 2cm proximal resection margin for Siewert-II/III tumors. On the other sides, due to more advanced tumor stage of patients in China when compared with Japan and Korea. It is necessary to conduct a randomized control study to analyze the length of resection margin in advanced adenocarcinomas of esophagogastric junction. Therefore, this study was aimed to include those Siewert II/III tumor patients in Gastrointestinal Surgery Department, West China Hospital, Sichuan University to analyze the relationship between the length of proximal resection margin and survival outcomes.

This study aims to show that the addition of carboplatin and paclitaxel chemotherapy to a palliative course of external beam radiation treatment improves both dysphagia relief and patient quality of life in patients with unresectable esophageal cancer.

A Phase 2 Study to Evaluate Adjuvant OBI-833/OBI-821 Therapy in Patients With Locally Advanced, Globo H-Positive Esophageal Cancer at High Risk for Recurrence

In this clinical trial, patients with gastric and gastroesophageal junction adenocarcinoma will be included. Treatment with curative intent will be given with chemotherapy for 4 cycles with fluorouracil, oxaliplatin and irinotecan preoperatively followed by surgery, and then additionally 4 cycles of the same chemotherapy postoperatively. The standard treatment today is preoperative treatment with fluorouracil and oxaliplatin pre-and postoperatively. The rationale for this trial is, that the addition of irinotecan might improve treatments results.

This randomized phase III trial is to compare simultaneous modulated accelerated boost with standard dose radiotherapy given together with chemotherapy in treating patients with esophageal squamous cell carcinoma.

Since multiple studies have demonstrated that PET can identify responders and non-responders to induction chemotherapy, using FDG-PET imaging to guide treatment decisions has prompted interest in clinical practice. The aim of this study was to evaluate whether changing chemotherapy regimen during radiation based on PET response to induction chemotherapy can improve clinical complete response (cCR) in patients with unresectable esophageal squamous cell carcinoma (ESCC).

Incurable oesophageal cancer remains a global problem and in South Africa the vast majority of patients with oesophageal cancer have advanced disease at first presentation and are not curable. Likely the most distressing symptom of advanced cancer in the oesophagus is dysphagia, which is the inability to swallow solids and later also liquids. This is successfully addressed in most cases by the placement of a stent in the oesophagus which opens the area of obstruction. When placed in the lower oesophagus, one of the major drawbacks of these stents is that they disrupt the anti-reflux mechanism of the oesophago-gastric junction, which can result in severe acid reflux, severely impacting the quality of life of the patient. To address this problem, a range of approved anti-reflux stents have been developed and tested in numerous trials. To date, the evidence is conflicting and there is insufficient current evidence to support the routine use of these stents. However, the trials are not all similar in how the acid reflux was measured or what type of stent was used. Furthermore, the use of anti-reflux medication, such as proton pump inhibitors, which may help reduce reflux, are not standardised across the trials and make further conclusions about these stents difficult to interpret. No data from Sub-Saharan Africa on the use of anti-reflux stents in these patients is available. South Africa faces a large burden of incurable oesophageal cancer and improving the quality of life of these patients is of paramount importance. This randomised controlled trial aims to investigate whether anti-reflux stents do indeed reduce acid reflux in patients with incurable oesophageal cancer compared to conventional oesophageal stents that do not have such an anti-reflux mechanism. Reflux will be measured using patient questionnaires about reflux, and other quality of life parameters, and will also be objectively measured using oesophageal scintigraphy, which has not been used in previous similar trials.

This clinical trial collects biospecimen samples to create a personalized ctDNA test to guide treatment for patients with gastrointestinal cancer with peritoneal carcinomatosis. Deoxyribonucleic acid, or DNA, is the material that carries all the information about how a living thing will work and function. Everyone is born with the same DNA in all our cells throughout our body. Sometimes, some of the cells in the body develop abnormalities in the DNA that cause those cells to grow abnormally and uncontrollably. Cancer occurs when there is abnormal and uncontrolled growth of cells. The DNA in cancer cells is therefore different from the DNA someone is born with. The Signatera ctDNA assay is a laboratory test that takes tumor (cancer) tissue and evaluates it for unique tumor DNA. This evaluation is used to create a report (otherwise known as an assay) personalized to each person's cancer. The personalized assay creates a personalized blood test to detect the level of abnormal DNA from the cancer that may be circulating in the body. Once this personalized blood assay is designed, it may be used to monitor a person's blood for the presence of ctDNA, which will indicate the presence or absence of cancer over time, even after treatment.

In the Netherlands, the incidence of esophageal adenocarcinoma (EAC) is increasing. In addition, EAC has a dismal prognosis. Therefore, screening for Barrett's Esophagus (BE) has stimulated interest. Although BE is a known precursor of EAC, a minority of patients with EAC are known with a previous diagnosis of BE. A non-invasive screening tool, such as breath testing, could select patients at risk for BE, after which unsedated transnasal endoscopy (uTNE) can confirm or exclude the diagnosis. The objective is to determine the accuracy and acceptability of a non-invasive screening strategy i.e. breath testing followed by uTNE for BE and EAC.
