The purpose of this study is to find the best model of combination of intraoperative radiotherapy(IORT) and postoperative radiochemotherapy for pancreatic cancer.
This study is a prospective, open-label, randomized controlled trial that enrolled previously untreated patients with locally advanced or metastatic pancreatic cancer. Participants were randomly assigned to receive either albumin-bound paclitaxel and gemcitabine, or albumin-bound paclitaxel, gemcitabine, and S-1 as first-line treatment. After patients who met the inclusion criteria signed an informed consent form, the study observed patients from the start of treatment until death, withdrawal of consent, loss to follow-up, or the end of the study. Eligible participants were randomly assigned in a 1:1 ratio to either the albumin-bound paclitaxel and gemcitabine treatment group (AG ) or the albumin-bound paclitaxel, gemcitabine, and S-1 treatment group (GAS). A total of 128 patients were planned for inclusion in the study, with 64 in each treatment group. Baseline data related to demographics, disease, treatment, adverse events, and tumor status were collected by the treating physician during the first visit and follow-up visits. Follow-up visits were conducted according to a fixed schedule, with survival assessed every three months through phone calls, WeChat, or by contacting other physicians. The final visit recorded patient death, withdrawal of consent, loss to follow-up, or the conclusion of the study.
The goal of this clinical trial is to learn if Adaptive Radiation Therapy (ART) is safe and effective in treating patients with locally advanced pancreatic cancer.
The main questions the study aims to answer are:
* Can ART improve how well radiation therapy targets the most aggressive cancer cells, while protecting the healthy tissue around the tumor?
* Can ART help reduce the side effects that participants may experience during treatment?
Participants will:
* Undergo CT scans to plan the exact location of the radiation treatment. During this process, 1-3 small markers may be placed in or near the tumor to help with the planning.
* Have a tumor biopsy, which involves taking a small sample of tissue from the cancer.
* Receive 5 radiation treatments every other day over a 2-week period.
* Provide blood samples before, during, and after your radiation treatment.
Single operater pancreatico-cholangioscopy is performed through the working channel of conventional duodenoscopes. A visual evaluation of the biliary and pancreatic ductal systems is completed and obvious or suspicious macroscopic lesions are targeted by biopsy forceps.
Evaluation of the usefulness of probe based confocal laser endomicroscopy in the evaluation of suspected premalignant lesions in the biliary duct and in the pancreas.
Aim of the study: To evaluate the value of Probe Confocal Laser Endomicroscopy (PCLE) in surgery for pancreatic tumor.
Methods:
Patients who are diagnosed with pancreatic tumor based on preoperative radiographic findings and will undergo radical resection are included in this clinical study. PCLE will be used in surgery to identify tumor is malignant or not, and surgeons will decide procedures of surgery based on outcomes of PCLE. In this present study, clinical trials will be divided into two phases. In the first phase, based on the definitive postoperative pathologic diagnosis, characteristic imaging structures that were collected by PCLE will be identified and primary diagnostic imaging criteria for pancreatic cancer would be developed. In the second phase, this criterion will be used for rapid intraoperative diagnosis of pancreatic cancer and predicting status of resection margin. In addition, accuracy of PCLE will be verified based on postoperative pathologic reports.
This study will assess the safety and efficacy of avutometinib (VS-6766) and defactinib in combination with gemcitabine and nab-paclitaxel in patients with Pancreatic Ductal Adenocarcinoma (PDAC) who have been previously untreated.
EUS-guided tissue acquisition is an established modality to diagnose malignancies of the pancreas and extrahepatic bile ducts. In the recent years fine needle biopsy (FNB) needles have largely replaced fine needle aspiration (FNA) for EUS-guided tissue acquisition. The Acquire FNB needle is a Franseen needle which has three symmetric cutting edges to obtain core tissue specimens. The Trident FNB needle has been recently introduced to the market for EUS-guided tissue acquisition. It has a multi-blade three-prong tip which one of the tips is longer than the other two.
The aim of this study is to prospectively compare these two types of needle in term of diagnostic accuracy, and safety profile.
The goal of this clinical trial is to test the effect of high-dose radiation therapy after initial chemotherapy in patients with locally advanced pancreatic cancer. The main question it aims to answer is:
• For patients with locally advanced pancreatic cancer that responded to initial chemotherapy (stayed stable or decreased in size), will high-dose RT (radiation therapy) contribute to improving treatment outcomes, enhancing quality of life, or increasing overall survival rates?
Participants will:
* Undergo an optional tumor biopsy.
* Be treated with high dose radiation therapy.
* Complete quality of life questionnaires.
* Donate research blood samples.
This is an open-label, nonrandomized, multicenter, dose escalation, and dose expansion first-in human (FIH) Phase 1 study to determine the safety, tolerability, PK, pharmacodynamics, and preliminary efficacy of INCA00186 when given alone or in combination with INCB106385 and/or retifanlimab in participants with specific advanced solid tumors; squamous cell carcinoma of the head and neck (SCCHN) and specified gastrointestinal (GI) malignancies have been selected as indications of interest for this study. Participants with CD8 T-cell-positive tumors will be selected as these tumors are more likely to respond to immunotherapy.
This phase II trial studies how well nab-paclitaxel and gemcitabine hydrochloride followed by radiation therapy before surgery work in treating patients with pancreatic cancer that can be removed by surgery. Chemotherapy drugs, such as nab-paclitaxel and gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving nab-paclitaxel, gemcitabine hydrochloride, and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
