Filter by:The primary goal of the research study is to determine whether treating pancreatic cancer patients with hydroxychloroquine in combination with gemcitabine before surgery is safe. The secondary goal is to determine if this new treatment regimen can effectively treat pancreatic cancer. This study will test the safety and efficacy of this combination in two parts, or phases.
Pancreatic cancer is a disease with an extremely poor prognosis. Such poor results are largely due to a high incidence of local or peritoneal recurrence even after curative R0 resection. If occult microscopic metastasis or residual cancer could be predicted correctly and identify the high risk of peritoneal recurrence, we may have chance to treat these patients by different multimodal locoregional or adjuvant therapy to improve the treatment outcome.
In extrahepatic bile duct cancer and pancreatic cancer, we will treat postoperatively with COX2 inhibitor and assess survival rate and recurrent rate.
A phase II study combining pertuzumab with erlotinib for patients with gemcitabine refractory pancreatic adenocarcinoma
The purpose of this study is to determine if pancreatic cancer/pre-cancer can be detected in early stages through the molecular analysis of stool samples. Investigators hypothesize that analysis of stool samples using digital melt curve (DMC) analysis, can be used as a sensitive and specific method to detect the common genetic abnormalities present in pancreatic cancers and pre-cancerous lesions of the pancreas.
Intraductal papillary mucinous neoplasm (IPMN) is a cystic pancreatic lesion that is a precursor to invasive pancreatic cancer. Differentiating whether an IPMN lesion is benign or malignant is critical, as the prognosis and management differs drastically, varying from surgery to clinical observation. However, despite physicians' attempts to characterize features concerning for malignancy, it is difficult to determine the likelihood of malignancy with conventional imaging techniques, and an accurate and non-invasive test to identify malignant IPMN is needed. Our hypothesis is that positron emission tomography (PET), a three-dimensional imaging that can identify cancer cells through their increased use of sugars, may be a superior test for differentiating between benign and malignant IPMN lesions. The investigators are planning a prospective pilot study of patients with IPMN who are undergoing surgery for their disease. These patients will undergo PET imaging, as well as computed tomography (CT), magnetic resonance imaging (MRI), and endoscopic ultrasound (EUS) as clinically indicated. Samples of tissue removed during surgery will be assessed and will serve as the gold standard for determining whether the lesion is benign or malignant. The investigators will evaluate the positive and negative predictive values of PET imaging for malignancy within IPMN lesions.
This is a retrospective observational study to determine the proportion of patients with a family history of pancreatic cancer and other malignancies among patients who have intraductal papillary mucinous neoplasm (IPMN). The investigators will be reviewing the demographic, clinical, radiologic, pathologic, and follow-up information from the Pancres Center database. The investigators will also conduct a chart review to collect information recorded by clinicians on each subject's family history of malignancy and personal history of malignancy. Results of this database and chart review will be incorporated into a datasheet in which all patient identifiers have been removed. The primary outcome will be the percentage of IPMN patients with at least one first-degree relative with pancreatic cancer or IPMN, or at least two first or second degree relatives with pancreatic cancer, IPMN, or malignancies related to pancreatic cancer syndromes, including colorectal, gastric, breast, ovarian, and melanoma neoplasms. Secondary outcomes will be the relative risk of IPMN subtypes of higher malignant potential (main duct or mixed type location), more advanced histology (carcinoma in situ or invasive carcinoma), and recurrence following surgical resection amongst subjects with a family history.
The primary aim of this study is to determine if mutations of BRCA1 and BRCA2 result in different precancerous pathways to pancreatic ductal adenocarcinoma (PDAC), as suggested in our validated mouse model. Genomic DNA will be isolated on normal tissue obtained from patients who underwent pancreatic resection for PDAC, intraductal papillary mucinous neoplasm (IPMN) or mucinous cystic neoplasm (MCN). Tissue will be examined for the three most common founder mutations in Ashkenazi Jews. In the cases in which BRCA1 or BRCA2 mutations are found, heterozygote normal and abnormal tissue will be examined to look for mutations in the other BRCA1 or BRCA2 allele. The interaction between other cancer causing genes with BRCA1/2 will also be evaluated by comparing the sequences of the other genes in pre-cancerous lesions. We hypothesize that BRCA1- and BRCA2-mediated pancreatic ductal adenocarcinoma progresses through the PanIN route, as seen in both BRCA1 and BRCA2 murine models of pancreatic cancer. We further hypothesize that BRCA1 mutations may enable an additional pre- neoplastic pathway through MCN, and that IPMN may embody yet another pre- neoplastic pathway.
The aim of this study is to determine the frequency of the three most common BReast CAncer gene 1 (BRCA1) and BReast CAncer gene 2 (BRCA2) genetic mutations that are commonly found in Ashkenazi Jewish patients with pancreatic cancer. Testing for BRCA1 and BRCA2 mutations in relatives of hereditary pancreatic cancer patients may have a significant impact; allowing for early screening, treatment, and resection of pre-malignant tissue or malignant lesions.
The specific aims of this project are to create a registry, as well as a biospecimen bank for individuals with pancreatic disease (e.g. pancreatic adenocarcinoma, pancreatitis, intraductal papillary mucinous neoplasm (IPMN) mucinous cystic neoplasm (MCN), and pancreatic intraepithelial neoplasia (PanIN) or have been determined to be at high-risk for pancreatic cancer. Biospecimen can be defined as blood, urine, tissue, stool, or saliva samples. Therefore, no hypothesis is to be tested. The personal data derived from the registry, correlated with biological information derived from the biospecimens will allow for future investigative studies of pancreatic cancer etiology and tumor biology. The long-term goals of the study are to advance the knowledge of the etiology and epidemiology of pancreatic cancer. It is anticipated that the knowledge derived will ultimately lead to improvements in the diagnosis, prevention, detection,and treatment of pancreatic cancer.
