Filter by:Even after the wide introduction of chemo/radiotherapy in the treatment algorithm, adequate surgery remains the cornerstone of gastric cancer treatment with curative intent. A proper D2 lymphadenectomy is associated with improved cancer specific survival as confirmed in Western countries by fifteen-year follow-up results of Dutch and Italian randomized trials. In clinical practice, the total number of harvested lymph nodes is often considered as a surrogate marker for adequate D2 lymphadenectomy; nonetheless, the number of retrieved nodes does not necessarily correlate with residual nodes, which intuitively could represent a more reliable marker of surgical adequacy. The availability of an efficient tool for evaluating the absence of residual nodes in the operative field at the end of node dissection could better correlate with survival outcomes. The goal of this multicentric observational prospective study is to test the reliability of a new score (PhotoNodes Score) created to rate the quality of the lymphadenectomy performed during minimally invasive gastrectomy for gastric cancer. The score is assigned by assessing the absence of residual nodes at the end of node dissection on a set of laparoscopic/robotic high quality intraoperative images collected from each patient undergoing a minimally invasive gastrectomy with D2 node dissection. Ideally, this tool could be a new indicator of the quality of D2 dissection and could assume a prognostic role in the treatment of gastric cancer.
This is a multi-center, prospective, randomized controlled study aimed at compareing the impact of stapler reinforcement patches versus standard staplers on postoperative complications in gastrojejunostomy.
This study aims to develop a multimodal model combining radiomic and pathomic features to predict pathological complete response (pCR) in advanced gastric cancer patients undergoing neoadjuvant chemotherapy (NAC). The researchers intended to collected pre-intervention CT images and pathological slides from patients, extract radiomic and pathomic features, and build a prediction model using machine learning algorithms. The model will be validated using a separate cohort of patients. This research intend to build a radiomic-pathomic model that can outperform models based on either radiomic or pathomic features alone, aiming to improve the prediction of pCR in gastric cancer.
The aim of this study is to test the efficacy and safety of immunotherapy plus chemotherapy on people with a relatively rare type of gastric cancer. Participants will take the anti-PD-1 inhibitor (Tislelizumab) and platinum-based chemotherapy (oxaliplatin + capecitabine or oxaliplatin + S-1) in a 3-week cycle, followed by a radical operation after 6 cycles.
The goal of the study is to learn about Safety and efficacy of preoperative adjuvant SOX regimen combined with PD-1 antibody versus FLOT Regimen with PD-1 antibody in localized deficient mismatch repair gastric cancer. The main question it aims to answer are: - Safety and efficacy of preoperative adjuvant SOX regimen combined with PD-1 antibody versus FLOT regimen with PD-1 antibody for the treatment of localized deficient mismatch repair gastric cancer - Disease-free survival of preoperative adjuvant SOX plus PD-1 antibody and FLOT plus PD-1 antibody for dMMR and locally advanced gastric cancer. Participants will be divided into two groups to use a FLOT chemotherapy regimen plus PD-1 antibody and a SOX chemotherapy regimen plus PD-1 antibody. Researchers would compare tumor regression grade, adverse effects and survival benefit of two preoperative adjuvant regimens.
The goal of this observational study is to learn about the long-term effect of surgery in metastatic gastric cancer patients who are accessed as having opportunity for surgery under Multi-disciplinary Team (MDT) evaluation. The main question it aims to answer is: Does surgery extend survival time in metastatic gastric cancer patients who are accessed as having opportunity for surgery under Multi-disciplinary Team (MDT) evaluation?
This trial plans to enroll many patients with advanced solid tumors to complete GK01 cell transfusion, including but not limited to advanced gastric cancer, esophageal cancer, cervical cancer, triple-negative breast cancer, and non-small cell lung cancer. For patients with advanced solid tumors eligible for inclusion, autologous tumor-reactive T cells (experimental drug GK01) were cultured and prepared, and a certain dose of GK01 cells was given according to the cell transfusion plan, and the safety and tolerability of the patients after transfusion were observed. Exploratory evaluation of pharmacokinetic/pharmacodynamic profiles following reinfusion and initial evaluation of efficacy of investigational drug GK01 cells according to RECIST 1.1 criteria.
The aim of this project is to study the presence of cancer-associated adipocytes in oesogastric cancers and their possible links with myosteatosis. This research project has a retrospective component, the aim of which is to analyse the body component based on imaging in patients with oesogastric neoplasia in order to determine the incidence of myosteatosis and to study the relationship with oncological and prognostic data. The second part of the project is prospective and will collect biological material (skeletal muscle, adipose tissue, tumour, blood) for histological, molecular and genomic analyses and will analyse muscle function in patients with oesogastric cancer. It will address the role of adipocytes in the tumour microenvironment of oesogastric cancer, focusing on their interactions with the observed muscle myosteatosis and prognosis. In the future, it will help to identify signalling pathways, targets and patients who could benefit from appropriate treatment.
To explore the consistency between result of PTC drug screening tests and actual clinical outcome for patients with advanced malignancy.
A complete omentectomy is typically recommended during radical total gastrectomy for gastric cancer, though its impact on survival remains unclear. This study aimed to assess the frequency and risk factors of metastases in the greater omentum in gastric cancer patients undergoing gastrectomy. It will involve a single prospective cohort of consecutive patients who underwent total gastrectomy with complete en bloc omentectomy and modified D2 lymphadenectomy. Post-surgery, the omentum will dissect from the gastrectomy specimen beyond the gastroepiploic vessels and examine separately for pathological assessment. The primary outcome will focus on the detection of omental metastases.
