Objective: To evaluate the impact and cost-effectiveness of FDG-PET/CT (PET) and diagnostic laparoscopy (DLS) in addition to initial staging by CT and gastroscopy in patients with advanced gastric cancer. Hypothesis: The study hypothesizes that performing DLS and PET for advanced gastric adenocarcinomas results in a reduction in the number of futile gastrectomies performed and a favorable cost-effectiveness. According to the literature, in 27% of patients a futile gastrectomy can be prevented, and the annual cost-reduction is an estimated €916.438. Study design: The study design is a prospective observational study. Study population: The study population consists of patients with a surgically resectable, advanced gastric adenocarcinoma (cT3-4a,N0-3,M0), that are scheduled for treatment with curative intent after initial staging with gastroscopy and CT. Usual care / comparison: Both PET and DLS were recently included in the new Dutch guidelines for the treatment of gastric cancer, as staging modalities for advanced (T3-4) tumors after initial staging. The costs of the study population will be compared to retrospective data of patients who underwent curative surgery (gastrectomy) after initial staging with CT alone. Outcome measures: The primary outcome of this study will be the proportion of patients in whom the PET or DLS lead to a change in treatment strategy. The accuracy of each modality will be analyzed separately. Secondary outcome parameters will be diagnostic performance, morbidity and mortality, quality of life, cost-reduction and cost-effectiveness. Sample size: Based on the expectation that 22% of patients will have a change in treatment strategy, at least 239 patients will be needed for this study to demonstrate that the diagnostic modalities in the new guideline are break-even. Approximately 543 patients will be eligible for the study in 36 months. Cost-effectiveness analysis: A state-of-the-art cost-effectiveness analysis and budget impact analysis will be performed on the additive value of PET and DLS by both prospective and retrospective data collection
This study is designed to evaluate the impact of muscle relaxation during laparoscopic gastrectomy on oncological benefit, especially with obese patients over BMI 25. The primary endpoint is number of harvested lymph node that is critical point regarding quality of surgery in gastric cancer treatment. The secondary endpoint is intraoperative bleeding, surgeons' satisfaction. The patients were randomly assigned to two groups using a computer-generated randomization table : 196 persons - Deep neuromuscular block group (98persons) - Moderate neuromuscular group (98persons)
Background: A new cancer therapy involves taking white blood cells from a person, growing them in the lab, genetically modifying them, then giving them back to the person. This therapy is called gene transfer using anti-KRAS G12V mTCR cells. Objective: To see if anti-KRAS G12 V mTCR cells are safe and can shrink tumors. Eligibility: Adults at least 18 years old with cancer that has the KRAS G12V molecule on the surface of tumors. Design: In another protocol, participants will: Be screened Have cells harvested and grown Have leukapheresis In this protocol, participants will have the procedures below. Participants will be admitted to the hospital. Over 5 days, participants will get 2 chemotherapy medicines as an infusion via catheter in the upper chest. A few days later, participants will get the anti-KRAS G12V mTCR cells via catheter. For up to 3 days, participants will get a drug to make the cells active. A day after getting the cells, participants will get a drug to increase their white blood cell count. This will be a shot or injection under the skin. Participants will recover in the hospital for 1-2 weeks. They will have lab and blood tests. Participants will take an antibiotic for at least 6 months. Participants will have visits every few months for 2 years, and then as determined by their doctor. Visits will be 1-2 days. They will include lab tests, imaging studies, and physical exam. Some visits may include leukapheresis or blood drawn. Participants will have blood collected over several years.
Background: Gastric cancer is a leading cause of cancer deaths around the world. This disease is a serious problem in places like East Asia, Central and South America, and Eastern Europe. Researchers want to study the causes of gastric cancer and its precursors. They want to reduce the number of people with stomach cancer. Objectives: To learn more about bacteria factors and other causes of gastric cancer. To study potential markers associated with precancerous gastric lesions (intestinal metaplasia). Eligibility: Adults ages 40-70 years at certain hospitals in Chile who: Are going to have upper gastrointestinal endoscopies OR have stomach cancer and need surgery Design: Participants will give gastric tissue samples. Some participants will donate a portion of the stomach tissue that is removed as part of their clinical care. Participants will give access to reports of their stomach exam. They will allow researchers to photograph the microscope slides of their tissue samples. Participants will answer questions. The topics of the questions include: Age, height, weight Education Habits including tobacco and alcohol Personal and family history of disease Reproductive history Diet Some participants will give blood, urine, saliva, and stool samples. Study staff will collect the blood. They will tell the participants how to collect the other samples themselves.
This project is a multi-center, prospective, randomized controlled clinical observation the safety and efficacy that stage IV limited peritoneal metastasis of gastric cancer patients accept hyperthermic intraperitoneal chemotherapy plus neoadjuvant chemotherapy with CRS and systemic chemotherapy. With advanced-stage gastric patients of confined to the peritoneal as the research object, with median progression-free survival and overall survival, adverse events as the end points.

This is a multicenter Phase 1b, open-label study to assess safety, tolerability, preliminary efficacy, and pharmacokinetics (PK) of cabozantinib taken in combination with atezolizumab in subjects with multiple tumor types, including advanced urothelial carcinoma (UC) (including bladder, renal pelvis, ureter, urethra), renal cell carcinoma (RCC), castration-resistant prostate cancer (CRPC), non-small-cell lung cancer (NSCLC), triple negative breast cancer (TNBC), ovarian cancer (OC), endometrial cancer (EC), hepatocellular cancer (HCC), gastric cancer/gastroesophageal junction cancer/lower esophageal cancer (GC/GEJC/LEC), colorectal cancer (CRC), head and neck (H&N) cancer, and differentiated thyroid cancer (DTC). The study consists of two stages: in the Dose Escalation Stage, an appropriate recommended cabozantinib dose for the combination with standard dosing regimen of atezolizumab will be established; in the Expansion Stage, tumor-specific cohorts will be enrolled in order to further evaluate the safety and efficacy of the combination treatment in these tumor indications. Three exploratory single-agent cabozantinib (SAC) cohorts may also be enrolled with UC, NSCLC, or CRPC subjects. One exploratory single-agent atezolizumab (SAA) cohort may also be enrolled with CRPC subjects. Subjects enrolled in the SAC cohorts and SAA cohort may receive combination treatment with both cabozantinib and atezolizumab after they experience radiographic progressive disease per the Investigator per RECIST 1.1. Due to the nature of this study design, some tumor cohorts may complete enrollment earlier than others.
Evaluating the application value of a new circulating tumor cell detection method for advanced gastric cancer patients in prediction of the prognosis and early evaluation of the result of postoperation adjuvant chemotherapy.
Rationale: For patients with peritoneal metastases of gastric origin, there is no consensus on the optimal treatment strategy. Several Asian and Western studies demonstrated hyperthermic intraperitoneal chemotherapy (HIPEC) and cytoreductive surgery (CS) to result in a prolonged survival compared to palliative systemic treatment. Morbidity and mortality rates of HIPEC and CS appear to be acceptable. In the Netherlands, this treatment is not yet introduced, therefore patients with peritoneal metastases of gastric origin are precluded from surgery and will be treated with palliative chemotherapy or best support of care. Objective: To assess the safety and feasibility of HIPEC and CS in Western patients with peritoneal metastases of gastric cancer, in terms of morbidity and mortality. Secondary objective is to determine the effect on survival and recurrence. Study design: Mono centre prospective phase II single-arm feasibility study. Study population: Western patients diagnosed with resectable (cT1-4b, N1-3) gastric cancer with clinical or pathologically proven peritoneal metastases without distant metastases. Intervention: Hyperthermic Intraperitoneal Chemotherapy (HIPEC) and Cytoreductive Surgery (CS) with Cisplatin. Main study parameters/endpoints: Primary outcome is the safety and feasibility of the intervention, measured by the percentage of overall surgical complications grade ≥3 as stated by the Common Terminology Criteria for Adverse Events. Secondary outcomes are intraoperative events, postoperative morbidity and mortality, postoperative recovery, including quality of life, and disease free- and overall survival. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The additional burden for the patient mainly consists of HIPEC and CS.Furthermore, patients will undergo additional staging in order to exclude unresectable disease, and neoadjuvant chemotherapy regimen (3 drugs) instead of a palliative chemotherapy regimen (2 drugs). Postoperative care and outpatient visits are performed according to current protocols on HIPEC and CS for colon cancer and nation-wide protocols on gastric cancer surgery. The study is associated with a high risk classification. As there is a potential survival benefit, a small chance for curation and possibly a higher quality of life, we consider the additional burden and risks justified. This study is designed as a one group study, which eliminates group relatedness.
