Filter by:Pancreatic cancer is a highly lethal disease. Patients with resectable or borderline resectable disease may benefit from preoperative radiochemotherapy. However, only a subset of patients will respond to this potentially toxic and expensive treatment. Therefore, novel predictive markers are needed to determine treatment efficacy at an early stage. Preferably, these markers could be determined non-invasively and provide insight into the biology of pancreatic cancer. Pancreatic cancers are heterogeneous tumors. The tumor microenvironment is often characterized by large amounts of stroma, hypovascularization, and hypoxia. As these three factors can all contribute to treatment resistance, a quantitative assessment of these markers may aid in the prediction of response to preoperative radiochemotherapy. Moreover, these assessments may have prognostic value. Finally, further insight into the interrelation of these aspects of the tumor microenvironment can contribute to the evaluation of new targeted treatment options. Tumor cellularity and extracellular matrix composition can be assessed non-invasively in vivo by diffusion weighted magnetic resonance imaging (DWI) and tumor vascularity can be assessed by dynamic contrast enhanced magnetic resonance imaging (DCE-MRI). Finally, tumor hypoxia can be evaluated by T2* MRI and PET-CT, using the 18F-labeled hypoxic marker HX4. Objective of the study: The primary aim of the study is to assess whether DWI, DCE-MRI, T2*, and 18F-HX4-PET/CT predict overall survival in patients with pancreatic cancer treated with surgery and adjuvant chemotherapy or with neoadjuvant radiochemotherapy, surgery and adjuvant chemotherapy. Secondary aims of the study include the assessment of the predictive value of DWI, DCE-MRI, T2*, and 18F-HX4-PET/CT for pathological response to neoadjuvant chemoradiation, the correlation of DWI, DCE-MRI, T2*, and 18F-HX4-PET/CT with histopathological assessment of tumor stroma, vascularization, and hypoxia, and the assessment of the predictive value of these histopathological markers for overall survival.
This is a study to assess the motion of pancreatic tumors during radiation therapy using Computed Tomography (CT) Scans and an Active Breathing Control (ABC) Device.
Primary Objective: To estimate the rate at which radiotherapy to the primary or a metastatic lesion produces an immune response in patients with metastatic carcinoma of the pancreas. Secondary Objectives: To characterize the kinetics of an immune response induced by radiotherapy. To characterize the dependency of the immune response on prior exposure to chemotherapy.
This study is a prospective open phase-I study to investigate the safety and tolerability for administration of repeated doses of ALECSAT. Each patient will be followed up to 24 weeks from the initial blood donation to the last visit. However, the actual treatment starts on day 26, when the first single dose of ALECSAT is administered. The following administrations are given with 3 weeks intervals, i.e. at week 7 and 10. The patients are attending Kirurgisk afdeling K, Bispebjerg Hospital, and are followed by close examinations during the study period and at regular visits after completing the study as advised by the patient's responsible physician.
This is a randomized phase II trial that will examine the ability of the hydroxychloroquine to improve the clinical activity of a pre-operative regimen of gemcitabine and nab-paclitaxel in subjects with potentially resectable adenocarcinoma of the pancreas. Eligible subjects will receive 2 cycles of gemcitabine and nab-paclitaxel (day 1, 8, 15) with or without hydrocychloroquine followed by surgical resection. Primary endpoint will be histologic response as graded by Evans criteria. Secondary endpoints will be CA19-9 response and PET response. Pre and post treatment tissue biopsies will be obtained to assess for levels of autophagy in tumor, liver and peripheral blood.
The purpose of this study is to compare the effects of two specific exercise interventions and one standard care control arm on physical functioning.The investigators expect that supervised training is most beneficial to the patients. However, they also expect some benefit for patients in the home-based training.
In Brazil pancreatic adenocarcinoma represents 2% of tumors, and 4% mortality being an uncommon disease, however very aggressive.Only 20% of cases are indicated for curative surgery, of which only 20% are alive within 5 years. For locally, advanced or metastatic disease, since 1997, single chemotherapy with gemcitabine is the standard treatment for first line, with survival around 6 months approximately.There is no standard treatment regimen for second-line, however Paclitaxel demonstrated effect on second-line phase II study. Metformin is an oral hypoglycemic drug used for treatment of diabetes mellitus. There is a growing number of preclinical studies which show antitumor effect against pancreatic adenocarcinoma, probably due to the effect of anti-insulin growth factor (IGF-1). This study will add metformin to standard treatment for second line of locally advanced or metastatic pancreatic adenocarcinoma in ICESP previously treated with gemcitabine. The objective is to evaluate whether metformin improves the efficacy of the standard treatment with paclitaxel by clinical and radiological evaluation.
The purpose of this study is to compare whether there is a delay or prevention of recurrence or death in participants with surgically removed pancreatic cancer who then take nab-Paclitaxel in combination with gemcitabine compared to those who take gemcitabine alone.
This phase II trial studies how well combination chemotherapy with or without oregovomab followed by stereotactic body radiation therapy (SBRT) and nelfinavir mesylate works in treating patients with pancreatic cancer that has spread to nearby organs or tissues. Drugs used in chemotherapy, such as gemcitabine hydrochloride, leucovorin calcium, and fluorouracil, 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. Monoclonal antibodies, such as oregovomab, can block tumor growth in different ways by targeting certain cells. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using smaller doses over several days and may cause less damage to normal tissue. Drugs, such as nelfinavir mesylate, may make tumor cells more sensitive to radiation therapy. Giving combination chemotherapy with or without oregovomab followed by SBRT and nelfinavir mesylate may kill more tumor cells.
The Whipple procedure is associated with increased readmission rates for infection, pancreatic leak, and failure to thrive/malnutrition. The purpose of this study is to develop an evidence based perioperative nutrition plan to improve patient outcomes. The study has two specific aims including evaluation of feasibility of implementing an evidence based perioperative nutritional plan for patients undergoing Whipple and evaluation of impact of a standard perioperative nutritional plan on primary outcome of readmission rate and secondary outcomes of readmission cause, length of stay for initial hospitalization and/or readmission, post surgical complications (surgical site infections, pancreatic leak, sepsis, delayed gastric emptying), and nutritional status (PG-Subject Generated Assessment scores, BMI, albumin, pre-albumin, and method of oral intake). Categorical variables including readmission rate, readmission cause, post-surgical complications and nutritional status will be compared by chi-square test between intervention and control group. Length of stay for initial hospitalization and readmission will be compared by non parametric Wilcoxon test between two groups. Descriptive statistics will be used to describe the sample. There are no risks to the study participants.
