Active clinical trials for "Esophageal Neoplasms"

This phase I/II trial studies the side effects and best dose of olaparib when given together with ramucirumab and how well they work in treating patients with gastric or gastroesophageal junction cancer that has spread to other places in the body (metastatic), has come back (recurrent), or cannot be removed by surgery (unresectable). Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as ramucirumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving olaparib and ramucirumab may work better in treating patients with gastric or gastroesophageal junction cancer compared to ramucirumab and paclitaxel (a chemotherapy drug) or ramucirumab alone.

Resectable esophageal or junctional cancer requires medical treatment by radiotherapy and chemotherapy followed by surgery. Currently, one of the most commonly used chemotherapy treatment is the FOLFOX. It is a combination of three drugs administered intravenously: fluorouracil, oxaliplatin and folinic acid. This is the standard treatment. Another protocol of chemotherapy is widely used by certain European and American teams, due to promising results : a combination of two drugs administered intravenously: Paclitaxel and Carboplatin (CarboP-pacliT). At present, no clinical study has shown the superiority of one treatment over the other. The objective of this Phase II study is to clarify clinical practice by comparing these two chemotherapy treatments.

This phase III trial is studying how well the combination of chemoradiation or radiation works in resected locally advanced cancer of the esophagus or gastroesophageal junction.

This study compares outcomes with regard to the timing of resective surgery after neoadjuvant chemoradiotherapy (CRT) in cancer of the esophagus or gastric cardia. Patients are randomised to surgery either conventional 4-6 or 10-12 weeks after termination of CRT. The study hypothesis is that a longer delay improves histological response and decreases the risk of postoperative morbidity and mortality.

This randomized phase II trial studies how well paclitaxel with or without cixutumumab works in treating patients with esophageal cancer or gastroesophageal junction cancer that has spread to other places in the body (metastatic). Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Cixutumumab may kill cancer cells by blocking the action of a protein needed for cancer cell growth. Giving paclitaxel with or without cixutumumab may kill more tumor cells.

The purpose of this study is to find out whether sentinel lymph node (SLN) mapping with ICG dye and NIR imaging can be used to identify esophageal or esophagogastric junction cancer that has spread to the lymph nodes. If SLN mapping is successful in these types of cancer, surgeons in the future could identify the sentinel lymph nodes and only remove these instead of removing all the lymph nodes which is currently done.

Despite important clinical improvements, esophageal cancer surgery is still associated to a high rate of postoperative complications. Recent ERAS (Enhanced Recovery After Surgery) Society guidelines underline the possible role of prehabilitations' programs in reducing postoperative morbidity. In this trial, 200 patients, scheduled for esophageal cancer resection, will be randomly assigned to two groups (100 patients for each group). In both groups, patients will perform a basal evaluation with a physiotherapist, a nutritionist and a psychologist. In the treatment group, each patient will receive a tailored prehabilitative program and, during the 4 weeks before surgery, will be monitored constantly by each single specialist. A preoperative revaluation (the day before surgery) and follow up visits at 3 and 6 months will be performed for all patients. The incidence of postoperative complications, the length of hospital stay, and the reach of discharge criteria will be registered.

Endoscopic ultrasound (EUS) is unsatisfactory in distinguishing between T1a and T1b stage esophageal squamous cell carcinoma (ESCC). Consequently, the National Comprehensive Cancer Network guidelines recommend endoscopic resection (ER) as a diagnostic tool for substaging T1 stage ESCC. However, as an invasive approach, diagnostic ER is not an optimal approach especially for T1b cases as most of them might not be fully cured by ER. It is necessary to develop reliable and less invasive methods to distinguish between T1a and T1b stage ESCC. In our previous unicentral trial, we found that submucosal saline injection (SSI) significantly improved the diagnostic accuracy of EUS in differentiating between T1a and T1b stage ESCC. It can be used as an alternative to diagnostic ER for preoperative substaging T1 stage ESCC cases in remote regions where few endoscopists are able to perform diagnostic ER. The use of EUS and SSI would help T1b stage patients avoid invasive diagnostic ER. Therefore, we aim to conduct a multi-center clinical trail to examine whether SSI can improve traditional EUS accuracy in distinguishing between T1a and T1b stage ESCC.

This trial aims to assess changes in minimal residual disease (MRD) status before and after radical concurrent chemoradiotherapy combined with immunotherapy and adjuvant immunotherapy after neoadjuvant immunochemotherapy in patients with inoperable stage II-III esophageal squamous cell cancer (ESCC), and correlate with the efficacy of adjuvant immunotherapy.

This trial is a Phase II study. All patients are resectable Gastric or Gastroesophageal Junction Adenocarcinoma, Eastern Cooperative Oncology Group (ECOG) performance status 0-1.The purpose of this study is to evaluate the efficacy and safety of cadonilimab combined with chemotherapy with or without AK117 neoadjuvantin treatment of resectable Gastric or Gastroesophageal Junction Adenocarcinoma.
