This study explores the relationship between pre-treatment dietary patterns, fecal microbiome, and response to chemotherapy in patients with pancreatic ductal adenocarcinoma.
This phase II trial tests how well gemcitabine, cisplatin and nab-paclitaxel given before surgery (neoadjuvant) works in treating patients with pancreatic cancer that can be removed by surgery (resectable) or that is borderline resectable. The standard treatment for resectable and borderline resectable pancreatic cancer is a combination of surgery and chemotherapy. Neoadjuvant therapy has been shown to improve overall survival compared to patients receiving surgery first. Gemcitabine is a chemotherapy drug that blocks the cells from making DNA and may kill tumor cells. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Nab-paclitaxel is an albumin-stabilized nanoparticle formulation of paclitaxel, an antimicrotubule agent that stops tumor cells from growing and dividing and may kill them. Nab-paclitaxel may have fewer side effects and work better than other forms of paclitaxel. Gemcitabine, cisplatin and nab-paclitaxel may be an effective neoadjuvant treatment option for patients with resectable or borderline resectable pancreatic cancer.
This phase II trial tests whether 68Ga-FAPI-46 positron emission tomography (PET)/computed tomography (CT) scan works to image cancer-associated fibroblasts (CAFs) in patients with pancreatic ductal adenocarcinoma (PDA) that has not spread to other parts of the body (localized). CAFs are a type of connective tissue cell that are found within or near cancerous tissue. Many CAFs express a protein called fibroblast activation protein (FAP) that are not found on healthy cells in large amounts. 68Ga-FAPI-46 is a radioactive chemical compound designed to circulate through the body and attach itself to FAP on PDA cells. A PET/CT scan is then used to detect the location of FAP lesions. PET scan is a procedure in which a small amount of radioactive glucose (sugar) is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the glucose is taken up. Because cancer cells often take up more glucose than normal cells, the pictures can be used to find cancer cells in the body. CT scan is a procedure that uses a computer linked to an x-ray machine to make a series of detailed pictures of areas inside the body. The pictures are taken from different angles and are used to create 3-dimensional (3-D) views of tissues and organs. Combining a PET scan with a CT scan can help make the image easier to interpret. PET/CT scans are hybrid scanners that combine both modalities into a single scan during the same examination. Giving 68Ga-FAPI-46 PET/CT may help doctors improve upon the diagnosis and management of PDA.
