The purpose of this study is to evaluate the value of ctDNA detection in the assessment of response rate to neoadjuvant chemotherapy in pancreatic cancer and to explore the correlation between ctDNA clearance and prognosis at different time points. Meanwhile, whole exome sequencing (WES) and RNA Sequencing (RNA-seq) of samples of responders and non-responders to neoadjuvant chemotherapy before and after treatment are performed to explore the mechanisms of drug resistance and provide guidance for clinical decision making.
RATIONALE: Drugs used in chemotherapy, such as gemcitabine and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving gemcitabine and cisplatin together with bevacizumab may kill more tumor cells.
PURPOSE: This phase II trial is studying how well giving gemcitabine and cisplatin together with bevacizumab works in treating patients with metastatic pancreatic cancer.
Postoperative pancreatic fistula is a potentially fatal sequela with substantial morbidity and mortality. A retrospective observational study was conducted in the surgical unit of Zagazig university hospital . Three hundred forty-seven patients were admitted with a clinical diagnosis of pancreatic fistula following both open and laparoscopic approaches for pancreatic benign and malignant tumors.
This trial evaluates whether testing of bile with nanopore sequencing results in earlier detection of bacteriobilia (bacteria in bile) that may lead to surgical site infections in patients undergoing surgery for benign or malignant pancreatic tumors. Surgical site infections are a significant source of poor outcomes in patients undergoing surgery for pancreatic tumors. In most patients who develop this kind of infection, the bacteria identified as causing the infection is also frequently found to be in the bile at time of surgery. Usage of nanopore sequencing for detection of bacteria in the bile of patients undergoing surgery may allow doctors to prevent surgical site infections or treat them sooner or more effectively.
The purpose of this study is to prospectively determine the effects of administering proton pump inhibitors (PPIs) following pancreaticoduodenectomy on postoperative outcomes. The findings of this study will help in avoiding the widespread use of PPIs during the immediate postoperative period following pancreatic surgery.
This study is designed to determine whether an investigational drug combination consisting of Gemzar®, Taxotere®, and Xeloda®, (called GTX) is safe and effective in treating advanced pancreatic cancer and to study and enhance the utility of PET scans in the evaluation of patients with pancreatic cancer.
This is a prospective observation cohort study to evaluate efficacy of different types of adjuvant therapy strategies, including chemoradiotherapy, chemotherapy alone, or no adjuvant treatment, for pancreatic ductal adenocarcinoma patients who received surgical resection of primary cancer.
This is a master prospective Phase I-II trial evaluating feasibility and efficacy of stereotactic magnetic resonance (MR) guided adaptive radiation therapy (SMART) in patients with cancer.
* The phase 1 study will evaluate the feasibility and safety of delivering SMART in patients with cancer.
* Phase 2 will evaluate efficacy of SMART with specific reference to tumor control and improvement in patient reported outcome measures
This multi-institutional trial aims to evaluate the potential benefit and side effects of adding fractionated stereotactic body radiotherapy/surgery (SBRT) before and after chemotherapy with gemcitabine for locally advanced pancreatic cancer.
DS-6051b is an orally administered inhibitor of the tyrosine kinases (ROS1) and neurotropic tyrosine kinase receptors (NTRK). This phase 1 first-in-human study evaluates safety and tolerability of DS-6051b in cancer subjects and identify a recommended phase 2 dose (RP2D). In addition, this study will also assess the pharmacokinetic (PK)/pharmacodynamic (PD) profiles and preliminary efficacy of DS-6051b.
