Filter by:Pancreatic cancer related pain can be difficult to control, even with high doses of narcotics, whose adverse effects may further impair quality of life. So EUS-CPN(endoscopic ultrasound guided celiac plexus neurolysis) is well established as an effective technique for controlling pain and reducing narcotic requirements in patients with pancreatic cancer. Recently, celiac ganglia can be visualized and accessed by endoscopic ultrasound. So it allows for direct injection into individual celiac ganglia to perform celiac ganglia neurolysis. This more precise delivery of therapeutic drug will offers the potential for enhanced efficacy and safety. To evaluate this hypothesis, this randomized controlled trial aimed to compare the efficacy and safety of EUS-CGN(Endoscopic ultrasound guided celiac ganglia neurolysis) vs. Bilateral EUS-CPN(Endoscopic ultrasound guided celiac plexus neurolysis) in providing relief from pancreas cancer-related pain.
The purpose of this study is to evaluate the efficacy of preoperative biliary drainage (PBD) which is performed prior to pancreatoduodenectomy candidates with obstructive jaundice by observing the prevalence of drainage and surgery related complications, hospital stay, medical cost and life quality compared to surgery alone. It is anticipated that PBD can reduce the prevalence of complications and improve the outcome of pancreatoduodenectomy.
The purpose of this study is to evaluate the validity and safety of a modified operative procedure of digestive tract reconstruction following pancreatoduodenectomy which enables the pancreatic juice and bile to bypass at the pancreatointestinal anastomosis and merge at gastrointestinal anastomosis. It is anticipated that this procedure can decrease the risk of post-surgical pancreatic leakage and preserve the patients' digestive function as well.
Macrophages are derived from monocytes recruited to the tumor site and stimulated by specific chemokines secreted by tumor cells. These tumor associated macrophages (TAMs) have been postulated as being involved in the progression of cancer. Based on our preliminary findings and on published data we hypothesized that macrophage-induced chemoresistance (MIC) can promote survival of pancreatic carcinoma cells during chemotherapy. The overall goal of this study is to evaluate the mechanism of MIC in an in-vitro model of Pancreatic ductal adenocarcinoma (PDA). methods: 1. The human PDA cell line Panc1 will be grown in suitable conditions. 2. Macrophages will be produced by incubating mononuclear cells from the blood of healthy donors in medium with M-CSF for 7 days. 3. TAMs will be generated by culturing these macrophages with tumor-culture conditioning medium (TCCM) of PDA Cells for an additional 72 hours. 4. Human pancreatic cells (PANC1) will be treated with gemcitabine following exposure to macrophages CM. 5. Cell proliferation will be quantified by light microscopy and by an XTT Cell Proliferation Assay Kit.
Pancreatic cancer is the second most frequent gastrointestinal malignancy. The overall survival is dismal. Especially for advanced pancreatic cancer, the conventional approaches are typically not curative and provide only minor increases in survivals in most cases. Dendritic cells (DCs) are powerful antigen-presenting cells (APCs) that play a pivotal role in the initiation, programming, and regulation of tumor-specific immune responses. Isolated DCs loaded with tumor antigen ex vivo and administered as a cellular vaccine have been found to induce protective and therapeutic anti-tumor immunity in experimental animals. Some clinical trials of DC vaccination for cancer patients have shown the induction of anti-tumor immune responses and tumor regression. Endoscopic ultrasound (EUS) is an established technique for the diagnosis and staging of pancreatic cancer. Endoscopic ultrasound guided fine-needle direct injection of dendritic cells vaccination into pancreatic tumors may be a promising treatment modality.Therefore, The purpose of the study is to evaluate the efficacy and safety of endoscopic ultrasound guided fine-needle injection of DCs vaccination into advanced pancreatic cancer
The aim of this study is to assess the effect of postoperative parenteral fish oil on clinical outcome and immune function after major laparoscopic abdominal surgery.
The EGFR is one of the most frequently overexpressed proteins in various cancers including lung cancer, and is related to tumor progression and resistance to most treatments. New treatment strategies targeting EGFR have been developed: "although much work remains to be done, erlotinib has already established itself as part of the therapeutic armamentarium against cancer"(A review of erlotinib and its clinical use. Tang PA, Tsao MS, Moore MJ. Expert Opin Pharmacotherapy. 2006 Feb;7(2):177-93.) Noninvasive PET/CT imaging of EGFR expression activity and mutation status in NSCLC could aid in the selection of patients for individualized therapy with EGFR kinase inhibitors. Whole-body noninvasive PET/CT imaging could estimate treatment-responsive vs. -resistant tumor burden before the initiation of therapy with EGFR inhibitors. The purposes of the study are: 1. To adjust an optimal treatment for patients with tumors that have high expression of EGFR by identification of this type of cancer using C11-Erlotinib PET/CT during pretreatment work-up; as well as to follow up after treatment response. 2. To recognize patients with advanced pancreatic cancer responding to treatment with erlotinib and to distinguish them from non-responders.
Pancreatic ductal adenocarcinoma (PDAC) has one of the worst prognoses of all human cancers and is considered as a sanctuary, resistant to most of the drugs used. Identification of new molecular targets involved in its pathogenesis is urgently needed and required both proper and innovative efficacy assessment. This proof-of-concept trial is studying the "dynamic" tumor response after the administration of a short course (4 weeks) neoadjuvant combination of gemcitabine and a Hedgehog inhibitor (Vismodegib) before surgery in patients with operable pancreatic cancer.
Colorectal cancers account for 783,000 new cases and cause 437,000 deaths per year across the world. Diagnosis in the early stages improves survival rates. Up to now, these cancers are mostly diagnosed only at later stages of the disease's course through histoimmune staining and molecular biology processes on the tissues biopsied from the gastrointestinal system under invasive diagnostic procedures of colonoscopy. Oral fluid presents a large protein complexity and has been recently used as a diagnostic biofluid for oral, as well as systematic diseases. Using oral fluid as a bio-marker for the colorectal cancer can be advantageous as it contains gastrointestinal fluids, in addition to bacteria and bacteria lysate, which can also serve as a bio-markers' source for colorectal cancers. Proteomic technologies provide the tools needed to discover and identify disease-associated biomarkers. The aim of the present study is to identify salivary bio-markers in patients suffering from colorectal cancers.
Systemic chemotherapy with cytotoxic drug is of limited effectiveness in advanced pancreatic cancer patients. Gemcitabine has been used as the first-line drug for advance pancreatic cancer for over two decades and combinations of gemcitabine with different chemotherapeutic drugs have been investigated to improve the outcomes of pancreatic cancer. However, no substantial improvement in patient survival has been achieved. Locoregional chemotherapy via intra-arterial perfusion or chemoemoblization takes advantage of the increasing local drug concentrations and reducing systemic toxicities. In this study, the investigators hypothesis that artery infusion chemotherapy had a better antitumor effect than systemic chemotherapy. The investigators will analyze and evaluate the effect and safety of an implanted percutaneous left subclavian artery port-catheter drug delivery system for regional chemotherapy of inoperable pancreatic carcinoma.
