Irreversible Electroporation Ablation Combined With Anti-PD(L)1 Therapy for Locally Advanced Pancreatic Cancer

Pancreatic cancer is a highly lethal malignant tumor of the digestive tract, especially local advanced pancreatic cancer (LAPC), which often loses the opportunity for surgical resection at the time of diagnosis. LAPC patients are often accompanied by tumor invasion of key anatomical structures such as major blood vessels, and traditional treatment methods such as radiotherapy and chemotherapy can slow down the progression of the disease, but the effect is limited, and the overall survival rate is still very low. There is a lack of effective treatment options for LAPC, especially in local control and prolonging survival, which exists a major limitation.

The surgical resection rate is low in LAPC, and the postoperative recurrence rate is high, and traditional radiotherapy and chemotherapy are difficult to completely eliminate the tumor. Immunotherapy has achieved breakthroughs in other tumors such as melanoma and non-small cell lung cancer, but the effect is limited in pancreatic cancer due to the immunosuppressive state of the tumor microenvironment (TME), which limits the efficacy of immunotherapy. In addition, the high invasiveness and rapid progression of pancreatic cancer further aggravates the treatment challenge.

Recent studies have shown that local ablation techniques such as irreversible electroporation (IRE) ablation not only can effectively ablate local tumors, but also may destroy the structural integrity of tumor cells, release tumor-associated antigens, and enhance the anti-tumor effect of the immune system. Therefore, IRE ablation may provide local control of pancreatic cancer for patients. At the same time, the combination of immune checkpoint inhibitors such as anti-PD(L)1 inhibitors may enhance the immune response in the tumor microenvironment and further improve the therapeutic effect. This combined treatment regimen is expected to overcome the limitations of single therapy and provide a new treatment strategy for local advanced pancreatic cancer.

Ropidoxuridine in Treating Patients With Advanced Gastrointestinal Cancer Undergoing Radiation Therapy

This phase I trial studies the side effects and best dose of ropidoxuridine in treating patients with gastrointestinal cancer that has spread to other places in the body and usually cannot be cured or controlled with treatment undergoing radiation therapy. Ropidoxuridine may help radiation therapy work better by making tumor cells more sensitive to the radiation therapy.

Improving Pancreatic Cancer Care by the Use of Computational Science and Technology

The goal of the IMPACT project is to set up a data sharing infrastructure between expert centers for pancreatic surgery that enables training, testing and validation of computer science tools to improve quality of care for patients with pancreatic cancer.

Radiofrequency Probe for Management of Unresectable Bile Duct and Pancreatic Cancer

The purpose of this study is to determine whether the use of an FDA approved endoscopic bipolar catheter (EndoHPB) will ablate tissue in malignant tumors within the pancreatic ducts.

The Prognostic Impact of Surufatinib for the Treatment of Advanced Pancreatic Ductal Adenocarcinoma

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive tumor with a poor prognosis, despite the emergence of chemotherapies, unmet medical needs and limited treatment options still exist for patients with metastatic PDAC (mPDAC). Surufatinib is a small-molecule tyrosine kinase inhibitor that targets vascular endothelial growth factor (VEGFR) 1, 2, 3, fibroblast growth factor receptor 1 (FGFR1), and colony stimulating factor 1 receptor (CSF-1R), and ex vivo experiments have demonstrated its effect on PC models.

A retrospective analysis of patients with PDAC who underwent surufatinib at Zhejiang Cancer Hospital (Hangzhou,China) from July 2022 to July 2023.The database was extracted from the preoperative demographics, blood markers, and surgical pathology information of patients undergoing surufatinib in the investigators' hospital.

Exploring the Impact of a Multi-modal Nutritional Intervention in Patients Undergoing Chemotherapy for Pancreatic Cancer (FEED Trial)

The study will examine if a multi-modal nutritional care package, with or without resistance training delivered with neoadjuvant chemotherapy, is effective at preventing loss of muscle strength during neoadjuvant chemotherapy for pancreatic cancer. There are two arms in this study: Control Arm will receive standard dietetic care and be prescribed standard pancreatic enzyme replacement therapy and oral nutritional supplement drinks with their neoadjuvant chemotherapy. The intervention Arm will have 3 additional dietitian visits and 6 physiotherapist visits that the control group will not.

Cixutumumab, Everolimus, and Octreotide Acetate in Treating Patients With Advanced Low to Intermediate Grade Neuroendocrine Carcinoma

This phase I trial studies the side effects and best dose of cixutumumab when given together with everolimus and octreotide acetate in treating patients with advanced low- or intermediate-grade neuroendocrine cancer. Monoclonal antibodies, such as cixutumumab, may find tumor cells and help carry tumor-killing substances to them. Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Octreotide acetate may interfere with the growth of tumor cells and slow the growth of neuroendocrine cancer. Giving cixutumumab together with everolimus and octreotide acetate may be a better treatment for neuroendocrine cancer.

Pancreatic Adenocarcinoma Gene Environment Risk Study

After informed consent, participants will be asked to complete a medical/family history questionnaire and provide a blood sample. Some participants may also be asked to provide a urine sample. Individuals undergoing procedures that require collection of biological samples for clinical purposes may have these samples saved for research purposes. Participants will also be asked for their permission for study investigators to access medical records and/or recontact them for updates to their medical and family histories. Data and biospecimens will be stored for potential future research projects.

Laparoscopy to Remove Pancreatic Tumors (Insulinomas)

This study will determine if laparoscopy can be used successfully to find and remove insulinomas (insulin-secreting tumors of the pancreas). These tumors are very small and often difficult to locate with magnetic resonance imaging (MRI), computed tomography (CT) or ultrasound. Invasive procedures, such as arteriograms (X-ray imaging using a contrast agent injected into the bloodstream through a catheter) and venous sampling are more successful but involve more patient discomfort and greater risk. This study will test whether laparoscopy can be used to replace some or all of these tests, as well as more extensive surgery.

Patients 11 years of age and older with low blood sugar (hypoglycemia) probably caused by an insulinoma may be eligible for this study. Candidates will have their hypoglycemia confirmed (with tests done under NIH protocol 91-DK-0066: Diagnosis and Treatment of Hypoglycemia) and will have CT imaging of the abdomen and MRI and ultrasound tests of the liver and pancreas. Patients whose tumors are not found by these studies will undergo arteriography of the pancreas and hepatic (liver) venous sampling.

Patients will then have laparoscopy. This surgical procedure uses a laparoscope-a tube-like device with special cameras and an ultrasound probe attached through which the surgeon can see and operate inside the abdomen. Laparoscopy is commonly done to remove the gallbladder and is also used to remove portions of the pancreas. For the current procedure, the surgeon makes small incisions in the abdomen, inserts tubes, fills the abdomen with gas, and proceeds to explore and operate on the pancreas. The surgeon will try to locate the tumor with the laparoscope. If the tumor is found, the location will be verified by the imaging study results. If it cannot be located by laparoscopy, the results of the imaging studies will be disclosed to enable removal. If the tumor cannot be successfully removed using the laparoscope, standard surgery will then be performed. If the tumor cannot be found though laparoscopy, imaging studies, or traditional surgery, the operation will be concluded without removing any of the pancreas. Medical treatment will be initiated and re-evaluation will be recommended after 6 months.
