Active clinical trials for "Esophageal Neoplasms"

Background: Lymph node status is an important prognostic parameter in esophageal carcinoma and an independent predictor of survival. Distribution of metastatic lymph nodes may vary with tumor location, tumor histology, tumor invasion depth and neoadjuvant therapy. Surgical strategy depends on the distribution pattern of nodal metastases but consensus on the extent of lymphadenectomy differs worldwide. Especially for adenocarcinoma the distribution of lymph node metastases has not yet been described in large series. Aim of the present study is to evaluate the distribution of lymph node metastases in esophageal carcinoma specimens following transthoracic esophagectomy with at least a 2-field lymphadenectomy. Methods: The TIGER-study is a multinational observational cohort study. All patients with a resectable esophageal or gastro-esophageal junction carcinoma in whom a transthoracic esophagectomy with a 2- or 3-field lymphadenectomy is performed in participating centers will be included. All lymph node stations will be excised and separately sent for pathological examination. Cluster analysis will be performed to identify patterns of metastases in relation to tumor location, tumor histology, tumor invasion depth and neoadjuvant therapy. Conclusion: TIGER will provide a roadmap of the location of lymph node metastases in relation to tumor histology, tumor location, invasion depth, number of lymph nodes and lymph node metastases, pre-operative diagnostics, neo-adjuvant therapy and survival. Patient-tailored treatment can be developed on the basis of these results, such as the the optimal radiation field and extent of lymphadenectomy based on the primary tumor characteristics.

This phase II trial investigates how well oral cryotherapy plus acupressure and acupuncture compared with oral cryotherapy alone work in decreasing chemotherapy-induced peripheral neuropathy in patients with gastrointestinal cancer who are receiving oxaliplatin-based chemotherapy. Acupressure is the application of pressure or localized massage to specific sites on the body to control symptoms such as pain or nausea. Acupuncture is the technique of inserting thin needles through the skin at specific points on the body to control pain and other symptoms. Cryotherapy uses cold temperature such as oral ice chips to prevent abnormally increased pain sensation. Giving oral cryotherapy with acupressure and acupuncture may work better in decreasing chemotherapy-induced peripheral neuropathy from oxaliplatin-based chemotherapy in patients with gastrointestinal cancer compared to oral cryotherapy alone.

This is a prospective cohort study designed to evaluate the treatment effect as well as predictive and prognostic factors with special emphasis on the clinical utility of ctDNA in plasma in patients with gastroesophageal cancer. Patients with gastroesophageal cancer are included in 5 separate cohorts scheduled for Surgical resection + perioperative chemotherapy (cohort 1) Neoadjuvant chemoradiotherapy followed by surgical resection (cohort 2) Definitive chemoradiotherapy with curative intent (cohort 3) Systemic therapy with the intent to prolong survival (cohort 4) Palliative treatment without the use of chemotherapy (cohort 5)

A high number of resected lymph nodes is an independent prognostic factor for improved survival after esophagectomy or gastrectomy for cancer. The quality of the lymphadenectomy is operator-dependent, as is the evaluation of the vascularization of the digestive structures that are anastomosed to restore digestive continuity after esophago-gastric resection. The aim of the study is to evaluate the impact of Indocyanine Green (ICG) and near infra-red (NIR) fluorescence imaging guidance in terms of number of lymph nodes resected and quality of gastrointestinal tract anastomoses in esophagogastric cancer surgery.

The Multi-OutcoMe EvaluatioN of radiation Therapy Using the Unity MR-Linac Study (MOMENTUM) is a multi-institutional, international registry facilitating evidenced based implementation of the Unity MR-Linac technology and further technical development of the MR-Linac system with the ultimate purpose to improve patients' survival, local, and regional tumor control and quality of life.

Skeletal muscle depletion and sarcopenia are the most typical features of cachexia, which occurs in 80% of patients with advanced esophageal cancer. Skeletal muscle consumption is an independent factor for poor prognosis, which negatively affects therapeutic toxicity, length of hospital stay, quality of life, complications, infection, and survival. The vast majority of patients had already experienced severe weight loss and skeletal muscle loss before the treatment began. During the concurrent chemoradiotherapy period, the intensity and long cycle of treatment, the toxic and side effects of treatment and the occurrence of radiation esophagitis would further lead to the increased demand for energy and decreased intake of patients, thus leading to continuous weight loss. Based on the previous literature, we suggest that baseline body composition has a significant impact on nutritional status, the incidence of adverse reactions, and survival during treatment. This research mainly for the thorough chemoradiation in patients with esophageal cancer, analysis treatment precursor composition, including skeletal muscle index, visceral fat area, body fat percentage and other parameters on the side reaction of chemoradiation, nutritional status and the influence of survival, and observe the baseline body composition and cure after 1 month of body composition changes of the impact on the survival time.

The purpose of this study is to observe and explore the effect of single or combined treatment of arotinib on the survival and prognosis of patients with advanced esophageal cancer in the real world, and to summarize the treatment experience of a wide range of people.

This study is to collect and validate regulatory-grade real-world data (RWD) in oncology using the novel, Master Observational Trial construct. This data can be then used in real-world evidence (RWE) generation. It will also create reusable infrastructure to allow creation or affiliation with many additional RWD/RWE efforts both prospective and retrospective in nature.

This phase I trial tests the safety, side effects studies chemotherapy followed by chemotherapy at the same time as radiation therapy (chemoradiation) before surgery (neoadjuvant) in treating patients with stage gastric (stomach) or gastroesophageal junction cancer . Chemotherapy drugs, such as docetaxel, oxaliplatin , leucovorin, fluorouracil, and capecitabine, 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. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving chemotherapy and chemoradiation before surgery may make the tumor smaller and may reduce the amount of normal tissue that needs to be removed.

Chronic stress refers to a special emotional state caused by unexpected stress for a long time, with an increasing incidence in the population. It can cause the body to release hormones such as cortisol and adrenaline. Tumor patients often experience changes such as psychological and emotional abnormalities, decreased quality of life, and impaired social relationships. Under stimulation, patients often experience negative reactions such as anxiety or depression. Epidemiological studies have shown that stress can affect the prognosis of malignant tumors, but the effect of stress on the efficacy and prognosis of esophageal cancer is still unclear. In animal models, chronic stress leads to an increase in tissue catecholamine levels, increased tumor burden, and increased invasiveness of ovarian cancer cells in mouse models. At the same time, stress can promote tumor neovascularization in mice. However, the mechanism by which chronic stress affects the occurrence and development of esophageal cancer is currently unclear. In addition to neurohumoral factors, chronic stress can cause changes in the gut microbiota, which in turn affects the body's digestion, metabolism, and immune function. It is a key gatekeeper of the immune response to tumors. Therefore, gut microbiota as an intermediate factor may also affect the occurrence and prognosis of various types of esophageal cancer.
