Active clinical trials for "Pancreatic Neoplasms"

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer. It may also help doctors predict how well patients will respond to treatment. PURPOSE: This research trial is studying the relationship between vitamin D biomarkers and survival in blood samples from patients with advanced pancreatic cancer.

This study focuses on four different lesions: pancreatic cysts, lymph nodes near the gastrointestinal tract, pancreatic masses and GIST tumors. On one hand, the results obtained during previous studies are more advanced for the assessment of the diagnostic performance of Cellvizio needle-based Confocal Laser Endomicroscopy (nCLE) system for Pancreatic cysts. Safety and technical feasibility have already been performed, and an interpretation criteria classification exists. On the other hand, results for pancreatic masses, Lymph nodes and GIST are less developed. the objectives of the study are to Assess the diagnostic performance of the Cellvizio needle-based Confocal Laser Endomicroscopy (nCLE) system in diagnosing masses and cystic tumors of the pancreas, lymph nodes, submucosal lesions of the GI tract Define/Validate descriptive criteria of nCLE sequences in masses and cystic tu-mors of the pancreas, lymph nodes, submucosal lesions of the GI tract

This is a feasibility study to perform image-guided liver biopsies in 25 patients who have pancreatic cancer with liver metastasis (cancer in the pancreas that has spread to the liver). This will contribute with samples for the bio-bank (bank of tumors) and develop xenografts (human tumors growing in mice) for further analysis of genes.

This study focuses on three different lesions: pancreatic cysts, lymph nodes near the gastrointestinal tract and pancreatic masses. On one hand, the results obtained during previous studies are more advanced for the assessment of the diagnostic performance of Cellvizio needle-based Confocal Laser Endomicroscopy (nCLE) system for Pancreatic cysts. Safety and technical feasibility have already been performed, and an interpretation criteria classification exists. On the other hand, results for pancreatic masses and Lymph nodes are less developed. The study therefore comprises two sub-studies, one on the pancreatic cysts, and another on pancreatic masses and lymph nodes. Cysts The primary hypothesis of the study is that using nCLE in addition to EUS-FNA and tissue sampling allows better characterization of pancreatic cysts and improves appropriate therapeutic decision-making. For physicians, integrating nCLE into the diagnostic algorithm of pancreatic cysts could impact patient management by : Ruling out malignancy for patients with benign appearing nCLE images. Characterizing more malignant tumors in the pancreas. Pancreatic masses and Lymph nodes The primary hypothesis of the study is that in vivo imaging of lymph-nodes near the gastrointestinal tract and pancreatic masses during EUS-FNA procedures is feasible and that descriptive criteria can be defined to further differentiate the different types of lesions.

This study involves the administration of a hypoxia marker, pimonidazole hydrochloride, taken orally approximately 24 hours before surgical resection of a pancreatic tumor in order to identify areas of lower oxygen content on tumor samples.

RATIONALE: Learning about biological markers in patients with pancreatic cancer and cachexia may help doctors predict patient outcome and may help the study of cancer in the future. PURPOSE: This laboratory study is examining biological markers in patients with pancreatic cancer experiencing weight loss.

RATIONALE: Collecting and storing samples of blood from patients with cancer and healthy participants to test in the laboratory may help the study of cancer in the future. PURPOSE: This study is collecting and storing samples of blood from patients with pancreatic cancer and healthy participants.

RATIONALE: Diagnostic procedures, such as visceral lymphatic mapping using isosulfan blue, may help find cancer of the pancreas, colon, stomach, small intestine, or gallbladder and find out how far the disease has spread. PURPOSE: This clinical trial is studying the side effects and how well visceral lymphatic mapping using isosulfan blue works in patients with cancer of the pancreas, colon, stomach, small intestine, or gallbladder.

Pancreatic cancer (PC) is usually diagnosed at a late stage when it is incurable, thereby limiting treatment to palliative care. Chemotherapy is one of the standard palliative care options. Due to the availability of different regimens with varying degrees of benefits and risks, clinicians and patients with advanced pancreatic cancer usually discuss treatment options in order to arrive at the most appropriate chemotherapy regimen for the patient. The use of information tools has produced positive results in explaining the benefits and risks of different treatment options for diseases like stage IV lung cancer, ovarian cancer, and colorectal cancer. However, there is no such tool for people with advanced pancreatic cancer. With over 80% of people with pancreatic cancer being diagnosed in the advanced stage, it would be beneficial to enhance effective decision-making with respect to treatment at this challenging time of the disease progression. The aim of this research is to investigate the potential of a web-based information tool to support decision-making about treatment options for people who have been diagnosed with advanced pancreatic cancer. A multiphase mixed methods design has been adopted for this research study. The identified phases are: (1) systematic review and network meta-analysis of reported randomised controlled trials (RCTs) in advanced pancreatic cancer; (2) focus groups/personal interviews with clinicians, and semi-structured interviews with patients and their relatives; (3) web-based information tool development; and (4) pilot test of the developed information tool with clinicians, patients, and relatives of patients

Gemcitabine plus S-1 (GS) prolonged progression-free survival (PFS) and greatly improved objective response rate (ORR) as well as disease control rate (DCR) of Asian patients with locally advanced and metastatic pancreatic cancer (PC). However, limited data of GS regimen exist on the efficacy and safety in the treatment of Chinese patients with advanced PC. To assess the efficacy and safety of gemcitabine plus S-1 (GS regimen) as the first-line chemotherapy in Chinese patients with advanced PC, we designed this prospective study.
