Filter by:Fibroblast activation protein (FAP) is overexpressed in cancer-associated fibroblasts (CAFs), which constitutes a major proportion of cells within the tumor microenvironment, especially in primary pancreatic ductal carcinoma (PDAC). In this prospective study, we aimed to evaluate the performance and value of 68Ga-FAPI-04 PET/CT in the patients with PDAC.
This is a prospective, multi-center, single arm, open label, non-randomized study to evaluate the ability of [68Ga]FAPI-46 to detect FAP expressing cells in patients with resectable or borderline resectable PDAC. The [68Ga]FAPI-46 PET scans will be acquired after initial staging using institutional standard methods. If the participant is prescribed neoadjuvant therapy, a second [68Ga]FAPI-46 PET scan will be performed within 21 days prior to planned surgical resection. This will be followed by histopathology and IHC analyses and comparison to resected PDAC tumor specimens.
Pancreatic head malignancies are aggressive cancers that are often inoperable when they are diagnosed. In the ~20% of patients who are diagnosed when the disease is still operable, surgery is the only treatment that can provide a chance of cure. Unfortunately, up to 75% of patients undergoing surgery will have the cancer come back (recur). One of the reasons for this is the challenge of removing the whole tumour with some surrounding non-cancerous tissue to ensure that every tumour cell has been removed. This is difficult because there are many structures very close to the pancreas (such as the blood vessels that supply the intestines) that cannot be removed. A recent review study of >1700 patients who had a Whipple's operation (the cancer operation that is performed to remove the head of pancreas) and found that whilst the majority of patients had cancer recurrence in distant sites (like the liver) that would not be affected by how the operation was performed, 12% of patients had the cancer recur just at the site of where the operation had been; this is known as 'local' recurrence. This suggests that a small amount of cancer was not removed at the time of surgery in these patients. Very few studies have looked at the relationship between the Computerised Tomography (CT) scan before surgery and the histology results (information about the tumour after it has been examined under the microscope) and whether this can predict exactly where the tumour recurs. If investigators can find factors that predict which patients get local only recurrence, investigators may be able to offer improved surgical techniques or other therapies during or immediately after the operation to these patients, hopefully leading to improved cure rates. This retrospective international study will look at these factors in patients who underwent a Whipple's operation for pancreatic cancer, bile duct cancer or ampullary cancer over a three year period between 2012 and 2015. Participating centres will provide data on pre-operative scans, complications around the time of surgery, any therapies (e.g. chemotherapy) that the patients had and if and where the cancer recurred. With this information, investigators hope to find ways to predict which patients will get local-only recurrence, so researchers can select them for future studies to see if additional treatments can improve the chance of cure from surgery for these patients.
Patients with inoperable pancreatic cancer have extremely poor prognosis with five year survival below 8% in Norway. Life-prolonging chemotherapy has very limited effect, but is the only therapeutic option for these patients. This tumor is characterized by poor uptake and chemoresistance. Toxic effects on healthy tissue restrict doses applied and maintenance of treatment intensity. This severely limits clinical outcome. Increasing the local uptake of chemotherapy has potential benefits for patients in connection to side effects, survival and possible cure. Treatment with Focused Ultrasound (FUS) combined with microbubbles (MBs) is proved promising to improve treatment response in animal and clinical trials. Ultrasound can induce biological effects deep inside the body without surgical intervention. This opens for local delivery of drugs at desired sites. FUS in combination with regular contrast MBs has been reported to influence the delivery of drugs to tumors. In this trial FUS and MB will be applied to locally advanced pancreatic cancers shortly after the administration of conventional chemotherapy. Primary aim of the trial is to investigate whether the effect of the cytostatic drug, measured in tumor volume, can be increased.
This is a Phase 1, open-label dose-escalation study to determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) and assess the DLT of JAB-3312. It is anticipated that approximately 24 subjects will be enrolled in the dose-escalation phase of the study. JAB-3312 will be administered orally once daily (QD) in 21-day treatment cycles.

PACAP-1 will evaluate to what extent an enhanced implementation of best practices in pancreatic cancer care leads to a prolonged survival and improvement of quality of life as compared to current practice.
Rationale: Pancreatic adenocarcinoma is a malignancy with a poor prognosis. Resection is the only curative option and still 5-year survival rate is less than 10 percent. However, most patients present with advanced disease and are provided with palliative care. The nature of the tumour and the intense stromal reaction around the tumour cells leave pancreatic adenocarcinoma relatively insensitive to chemotherapeutics. Current models, such as cell lines or patient derived xenografts, cannot provide predictive information in a clinically relevant timeframe. Organoids and organotypic culture systems have emerged as promising new culturing techniques that maintain some of the complexity of the tumour. As most patients are ineligible for tumour resection, this project will focus on metastases and will generate organoids from that tissue. Using a combination of organoids and organotypic systems, treatment (non)response can be predicted, which may provide a personalized treatment setting for patients with advanced pancreatic adenocarcinoma.
Pancreatic cancer represents the most lethal of the common malignancies, with a 5-year survival rate of less than 5%. For patients who, when are diagnosed of pancreatic cancer, are eligible for potentially curative resection, the mortality and morbidity rates after surgery can improve significantly, but who accounts for no more than 20% of all pancreatic patients. It is therefore an effective way to improve the treatment efficacy for pancreatic cancer by discovering novel detection methods for pancreatic cancer, especially at early stages. MicroRNAs have been proved in recent years as functional disease markers, and circulating microRNA-25 is reported of high pancreatic cancer specificity and can be used as a novel marker for pancreatic cancer. A detection kit "MicroRNA (microRNA-25) Qualitative Detection Kit (Fluorescent PCR Method)" is produced and proven to be effective in assisting the diagnosis of pancreatic cancer through clinical trials held independently in three state-level hospitals in China. To further validate the efficacy of the kit, the researchers in this study intend to compare the sensibility and specificity of microRNA-25 level detection and other diagnosis methods, including detection of conventional tumor markers (CA19-9, CA125, CA50, CEA) and imaging (CT, MRI, PET/CT), both in separation and combined, in the diagnosis of pancreatic cancer.
Pancreatic cancer represents the most lethal of the common malignancies with a 5-year survival rate of less than 5%. For patients who are eligible for potentially curative resection, despite mortality and morbidity rates after surgery have improved, the recurrence rate is up to 85% within 2 years. FOLFIRINOX (fluoropyrimidine/leucovorin plus irinotecan and oxaliplatin) has been proved to significantly improve the prognosis and is recommended as first line treatment in patients with advanced pancreatic cancer. However, the regimen is limited due to the severe adverse effects. Thus, the investigators replaced 5-FU and leucovorin in the FOLFIRINOX regimen with oral S-1, a new oral fluoropyrimidine derivative which was proved to be the well-tolerated and effectively in large III phase randomized clinical trial, to form the SIRIOX regimen. A phase I clinical trial from Japan found that SOXIRI (S-1, oxaliplatin and irinotecan) works in patients with advanced pancreatic cancer. In this study, the researchers intend to investigate the activity and safety of the combination of this regimen in patients with advanced pancreatic cancer, as first- or second-line chemotherapy.
