Filter by:This study aims to facilitate discovery and validation of tests for early detection in subjects at high risk for pancreatic ductal adenocarcinoma (PDAC) and to facilitate the use of state-of-the-art machine learning-based algorithms that utilize databases and images with the purpose of identifying early stages of pancreatic cancer, as well as people at high-risk.The study also aims to provide a platform for development of an interventional protocol for early detection of PDAC.
Pancreatic ductal adenocarcinoma (PDAC) can be divided into pancreatic head cancer (PHC) and pancreatic body/tail cancer (PBTC) according to the anatomical position of tumors. There is increasing evidence that tumors at different sites exhibit different genetic or molecular features and clinical manifestations, and can affect the survival and outcomes of PDAC patients. Studies have shown that the prognosis of PBTC is worse than that of PHC, which is partly attributed to the relatively late clinical presentation of PBTC patients and the lack of overt symptoms such as obstructive jaundice, which is common in PHC. However, it has also been shown that the worse survival of PBTC compared to PHC is not related to the disease stage. Previous studies have investigated the molecular differences between PHC and PBTC and found that the frequency of SMAD4 mutation in PBTC was significantly higher than that in PHC at early stages (I-II). In the late stage (III-IV), PBTC had higher mutation frequency of Kirsten rat sarcoma viral oncogene homolog (KRAS) and mitogen-activated protein kinase (MAPK) pathway, but lower frequency of genomic alterations which can be targeted by drugs. The above genetic and molecular differences may be related to the clinical differences between PHC and PBTC. However, the differences in microbial composition and metabolism between PHC and PBTC have not been fully studied and discussed, and their relationship with clinical manifestations and prognosis is also unclear. In this study, the investigators aimed to analyze the microbial and metabolic differences between PHC and PBTC through 16S ribosomal ribonucleic acid (rRNA) sequencing and untargeted metabolome analysis to further explore the etiology and pathogenesis of PDAC at different anatomical positions.
Compared to upper gastrointestinal (GI) malignancies, CRC patients generally present with satisfactory nutritional status at surgery and malnutrition is typically present in advanced stages of CRC. Therefore, in the latter surgery may not be offered with curative intent. Based on the current evidence, the role of OIN appears to be consolidated for malnourished patients undergoing surgery for gastrointestinal cancer. Regarding not malnourished patients, there is still no clear correlation between OIN and decrease in post-operative complications. Furthermore, whether OIN increases immune response within the tumour microenvironment is based on studies with poor number of patients.
This clinical trial tests how well surgical resection after chemotherapy given before surgery to make the tumor smaller (neoadjuvant) works to treat pancreatic cancer that has spread to nearby tissue or lymph nodes (locally advanced) and that cannot be removed by surgery (unresectable). In general, surgery is considered the most effective treatment for pancreatic cancer, especially when the cancer is localized and has not spread to other organs. However, most patients with pancreatic cancer are not candidates for surgical removal because the cancer has grown into or close to nearby arteries, veins, or organs and there is a concern of damaging these nearby structures. Researchers want to find out if surgery after neoadjuvant chemotherapy can be done safely to completely remove the tumor in patients with locally advanced and unresectable pancreatic cancer.
This clinical trial is studying advanced solid tumors. Solid tumors are cancers that start in a part of your body like your lungs or liver instead of your blood. Once tumors have grown bigger in one place but haven't spread, they're called locally advanced. If your cancer has spread to other parts of your body, it's called metastatic. When a cancer has gotten so big it can't easily be removed or has spread to other parts of the body, it is called unresectable. These types of cancer are harder to treat. Patients in this study must have cancer that has come back or did not get better with treatment. Patients must have a solid tumor cancer that can't be treated with standard of care drugs. This clinical trial uses an experimental drug called SGN-CEACAM5C. SGN-CEACAM5C is a type of antibody-drug conjugate or ADC. ADCs are designed to stick to cancer cells and kill them. They may also stick to some normal cells. This study will test the safety of SGN-CEACAM5C in participants with solid tumors that are hard to treat or have spread throughout the body. This study will have 3 parts. Part A and Part B of the study will find out how much SGN-CEACAM5C should be given to participants. Part C will use the information from Parts A and B to see if SGN-CEACAM5C is safe and if it works to treat solid tumor cancers.
BACAP-2 is a prospective biobank dedicated to the pancreatic adenocarcinoma including clinical data and biological samples from tumor. The aim is to enrich the previous propective collection BACAP in order to support future research projects.
The goal of this clinical trial is to evaluate the safety and preliminary efficacy of WX390 combined with Toripalimab in patients with advanced Gastric-type Endocervical Adenocarcinoma with STK11 mutations. The main questions it aims to answer are: - Pharmacokinetic (PK) characteristics of WX390 combined with Toripalimab treatment. - Safety and preliminary in combined therapy. Participants will be treated with WX390 orally and Toripalimab intravenously, and follow the efficacy and safety evaluation according to the protocol.
This study will assess the efficacy and safety of SHR-A1811 compared with treatment chosen by the investigator in participants with HER2-positive (defined as immunohistochemistry [IHC] 3+ or IHC 2+/in situ hybridization [ISH]+) gastric or GEJ adenocarcinoma (based on [American Society of Clinical Oncology (ASCO) College of American Pathologists (CAP) guidelines who have progressed on or after a first-line anti-HER2 therapy-containing regimen.
The study is a open-label, single-arm, multicenter, phase Ib/II trial assessing the efficacy of sacituzumab-govitecan for metastatic esophagogastric adenocarcinoma
The purpose of this study to find out whether adding trastuzumab and pembrolizumab to standard chemotherapy is an effective treatment for resectable HER2+ esophagogastric cancer.
