The purpose of this study is to determine whether the use of chewing gum effects postoperative ileus after pancreaticoduodenectomy

This study is a diagnostic study. Patients and healthy volunteers with clinically suspected or confirmed colorectal cancer, gastric cancer, pancreatic cancer and other malignant tumors with high expression of GPA33 will be recruited for PET/MR or PET/CT imaging targeting a GPA33-specific probe (in the case of [68Ga]Ga-NOTA-GPA33 nanobody) , to observe the reaction of volunteers and patients after injection of drugs, to evaluate the pharmacokinetics in vivo and the efficacy of diagnosis and staging, and to perform PET imaging in patients with contraindications. General information on the subjects' vital signs, clinical data, blood routine, liver and kidney functions and other biochemical indicators and other imaging data were collected, and histopathology of biopsy or surgical specimens was used as the final diagnostic criterion.

This is an open, two-stage, phase I study to evaluate the safety, tolerability, pharmacokinetics and preliminary efficacy of AB011 injection in patients with CLDN18.2-positive advanced solid tumors.

The aim of the study is to evaluate the feasibility defined as overall tolerance and toxicity as well as relative dose-intensity and cumulative dose delivered, of an association ofgemcitabine, oxaliplatin and radiotherapy in patients with locally advanced and unresectable, but non-metastatic pancreatic adenocarcinoma or cholangiocarcinoma

Pancreas cancer and precancerous cysts can be difficult to diagnose. Sometimes biopsies do not show cancer when cancer is actually present. We hypothesize that genetic differences exist in tissue that is malignant compared to nonmalignant. When patients present with a pancreas mass or cyst, we biopsy it by fine-needle aspiration during upper endoscopy with ultrasound guidance. We would like to use tissue obtained via endoscopic ultrasound guided fine needle aspiration to perform DNA microarray analysis, and compare the differences in gene expression level in the benign tissue compared to cancerous tissue in order to improve our diagnostic capabilities. DNA microarray measures gene expression level rather than germline mutations. The true diagnosis will be based on cytology, surgical pathology, or clinical followup. The performance of the microarray test as a diagnostic test will be compared to the performance of cytology.

We intend to establish an efficient method for plasma cfDNA extraction and Bisulfite transformation to facilitate the detection of DNA methylation status using multiplex fluorescence PCR. Meanwhile, we expect to identify several plasma methylation markers that can be highly sensitive for multi-cancer detection. Finally, we will provide a pan-cancer blood test that is easy to operate, low cost, accurate and easy to promote.

The purpose of this study is to evaluate the efficacy of vitamin C in improving the quality of life for metastatic pancreatic cancer patients who are resistant to chemotherapy.

Pancreatic cancer represents the most lethal of the common malignancies, with a 5-year survival rate of less than 5%. For patients who, when are diagnosed of pancreatic cancer, are eligible for potentially curative resection, the mortality and morbidity rates after surgery can improve significantly, but who accounts for no more than 20% of all pancreatic patients. It is therefore an effective way to improve the treatment efficacy for pancreatic cancer by discovering novel detection methods for pancreatic cancer, especially at early stages. MicroRNAs have been proved in recent years as functional disease markers, and circulating microRNA-25 is reported of high pancreatic cancer specificity and can be used as a novel marker for pancreatic cancer. A detection kit &#x0022MicroRNA (microRNA-25) Qualitative Detection Kit (Fluorescent PCR Method)&#x0022 is produced and proven to be effective in assisting the diagnosis of pancreatic cancer through clinical trials held independently in three state-level hospitals in China. To further validate the efficacy of the kit, the researchers in this study intend to compare the sensibility and specificity of microRNA-25 level detection and other diagnosis methods, including detection of conventional tumor markers (CA19-9, CA125, CA50, CEA) and imaging (CT, MRI, PET/CT), both in separation and combined, in the diagnosis of pancreatic cancer.

A single arm, open-label pilot study is designed to determine the safety, efficacy and cytokinetics of CAR T cells in patients with malignant tumors with positive antigen targets.

CAR T cells are genetically engineered to express single-chain variable fragment (scFv) targeting indication-specific antigens.

The investigational CAR T cells and proposed indications are as follows:

CAR-CD19 T cells for B cell leukaemia/lymphoma; CAR-BCMA T cells for myeloma; CAR-GPC3 T cell for hepatocellular carcinoma; CAR-CLD18 T cells for pancreatic carcinoma and adenocarcinoma of esophagogastric junction.

Pancreatic cancer has a very poor survival, due to late diagnosis and lack of sufficient treatment options for locally advanced tumors and metastasized patients. High dose radiotherapy with small margins seems feasible with current technical possibilities, e.g. by fiducial guided stereotactic radiotherapy. In this study, we want to evaluate safety and technical feasibility for cone beam CT guided stereotactic radiotherapy for locally advanced pancreatic carcinoma.
