Active clinical trials for "Stomach Neoplasms"

The purpose of the study is to compare two particular techniques of tissue (capillary vs wet-suction techniques) sampling during endoscopic ultrasound guided fine needle aspiration/biopsy (EUS-FNA/FNB) of a solid lesion to determine the diagnostic yield and procedure logistics (e.g. procedure time).

Reflexion on the therapeutic strategies to implement in patients at the end of life is advancing rapidly in France. However, beyond the choices presented to patients, sometimes even the decision to carry on, to limit or to stop treatments is also questioned. This decision is subjective; it is influenced by the patient's representation system (emotions, beliefs, values, practices, etc). In addition, even though he or she is the focus of the decision, the patient is not alone; other actors, accompanying the patient, play an important role in the final decision making. These actors, namely the doctors and close relatives, are also influenced in their decision making. This coexistence of representation systems may interfere with objective indicators that help in decision making (functional, clinical and biological) or with the knowledge acquired by doctors in their training and may complicate the decision-making process.

The purpose of this study is the validation of MMS test to detect active tumor growth in different cancer types before and after therapy, as well as in the course of therapy and for subsequent relapse control compared to standard methods (clinical examination, imaging, tumor markers). It should be consider whether the MMS test has comparable diagnostic accuracy, and thus can replace more expensive or invasive procedures in future.

To determine whether biomarkers assessed in blood samples can be used to detect individuals at risk for developing blood clots or worsening of their underlying disease. The ultimate goal of the study is to identify key biomarkers derived from blood that are most characteristic and informative of individuals who will go on to develop a clotting complication.

Endodrill is a new instrument for biopsy sampling in the GI-channel. The purpose of this study is as follows: Compare the Endodrill instrument with conventional biopsy forceps in terms of ability to establish the correct diagnosis of diffuse gastric cancer based on collected biopsies from tumor tissue.

This prospective study includes patients with histologically proven cancer of the esophagogastric junction (Siewert Type II and III) and the stomach. Aim of the study is to evaluate the accuracy of PET-CT for the preoperative assessment of lymph node metastasis. The evaluation includes a combination with standard diagnostic tools (endoluminal ultrasound, CT and diagnostic laparoscopy prior to neoadjuvant therapy). Standardized D2-lymphadenectomy is performed and individual lymph node stations (Nr 1-12 according to the Japanese classification) are histopathologically examined. Furthermore we evaluate the role of the PET-CT for early metabolic response evaluation in patients receiving neoadjuvant chemotherapy. Trial with surgical intervention

Enteral immunomodulating nutrition modifies the gastrointestinal microbiota as well as improves the intestinal barrier integrity in patients with gastric and colorectal cancer in the perioperative period. As a consequence, it contributes to the reduction of the incidence of postoperative complications and diarrhea, which is a side effect of anti-cancer treatment often used preoperatively in this group of cancers.

The purpose of this study is to evaluate the clinical safety and preliminary efficacy of antigen-specific cytotoxic T lymphocytes induced by dendritic cells infected by recombinant adeno-associated virus with CEA gene in the treatment of stage IV gastric cancer patients.

Patients with gastrointestinal cancer often experience physical deconditioning; this could lead to an increased risk of complications, especially when they require major abdominal surgical procedures. It has been suggested that physical training in the preoperative period could improve their condition, reducing the risk of complications. Although this topic has been investigated, it has not been established yet the best short preoperative aerobic exercise program to enhance the aerobic capacity in patients with gastrointestinal cancer who are going to be to surgical primary management, and consequently, to help patients dealing with the physiological stress involved in a surgical intervention. Main objective: To determine the efficacy and safety of a 4 weeks preoperative exercise program in patients with gastrointestinal cancer scheduled for primary surgery. Materials and methods: This is a Phase II single arm clinical trial that will include patients between 45 and 70 years, with confirmed gastrointestinal cancer (gastric, hepatic, colon or rectal cancer), without electrocardiographic abnormalities, and scheduled for primary surgery in 4 weeks or more since recruitment All the enrolled patients will receive a basal aerobic capacity assessment with the 6-minute walk test. Then, two physical therapist will prescribe them a supervised and individualized aerobic training program in 3 sessions per week during 4 weeks. Each session will last 50 minutes and will increase the heart rate target weekly (from 50% to 70% of the maximum heart rate). The aerobic exercise will be carried on a treadmill or in a stationary bicycle. The post intervention aerobic capacity will be measured at week 3 and 4 with the 6-minute walk test. The main efficacy outcome will be peak oxygen consumption (VO2 peak) and the safety outcomes will be exercise-related adverse events and the program adherence. This protocol was approved by the Instituto Nacional de Cancerología's Ethical Board

Background: It is estimated that in the Netherlands each year approximately 900 patients with gastric cancer or adenocarcinoma of the gastro-oesophageal junction are candidates for chemotherapy. Randomized studies comparing chemotherapy versus best supportive care have shown that survival and quality of life are prolonged with chemotherapy. However, no chemotherapy regimen is clearly superior with regard to prolongation of survival. Therefore, tolerability of treatment and ease of administration (outpatient compared to inpatient) are important considerations for the development of novel treatment schedules. Study design: This is an open-label, multicentre, phase II trial designed to evaluate the efficacy and safety of bevacizumab in combination with docetaxel, oxaliplatin and capecitabine chemotherapy (B-DOC) as first-line therapy in patients with inoperable locally advanced or recurrent and/or metastatic adenocarcinoma of the stomach or gastro-oesophageal junction. In case of HER2 positive inoperable locally advanced or recurrent and/or metastatic adenocarcinoma of the stomach or gastro-oesophageal junction trastuzumab is added to this regimen (B-DOCT). Study Endpoints: Primary endpoint Progression free survival defined as the time measured from B-DOCT study, Protocol version 3.0 dated January 18, 2011 Page 5 / 60 the day of registration to first progression or death. Secondary endpoints Toxicity Overall survival, defined as the time from registration to death Response rate defined as the percentage of partial and complete responses Duration of response defined as time from response to first progression Translational research on pharmacogenomic and biological factors that may predict treatment response.
