Filter by:Despite important therapeutic advances, pancreatic adenocarcinoma remains one of the cancers with a high mortality rate (4th leading cause of cancer death in the US in 2021), poor prognosis (5-year overall survival rate of 10%) and increasing incidence. Patients are often metastatic from the start or at an advanced stage at diagnosis, making curative treatment difficult to envisage. Although the gold standard of treatment for resecable pancreatic adenocarcinoma is initial surgery followed by adjuvant chemotherapy, considerable interest has emerged in a treatment strategy involving neoadjuvant therapy in patients at high risk for positive resection margins (R1) on initial imaging workup. The assessment of response to neoadjuvant therapy is complex, especially for the evaluation of vascular invasion with a high risk of overestimating residual invasion after neoadjuvant therapy. Accurate assessment of tumor size before and after neoadjuvant treatment is therefore crucial to identify good responders (according to RECIST 1.1 criteria) and thus improve the selection of patients who can benefit from curative surgery with healthy resection margins (R0). In clinical practice, tumor size assessment is performed by injected computed tomography (CT). The latter has certain advantages in terms of technical reproducibility, but has a number of limitations. Indeed, the delineation of the tumor mass in CT seems to be subject to a significant inter-observer variability. The same is true for vascular invasion. CT also seems to underestimate the size of the tumor compared to the anatomopathological examination of the surgical specimen. On the other hand, Magnetic Resonance Imaging (MRI) has been shown to be superior to CT in tumor detectability and diagnosis of malignancy in the presence of an indeterminate pancreatic mass. It has also been shown that tumor size, whether measured in diameter or volume, is frequently underestimated on CT compared to multiparametric MRI or pathological examination of the resection specimen. In the latest recommendations of the National Comprehensive Cancer Network (NCCN), MRI is indicated at diagnosis in non-metastatic patients with indeterminate liver lesions on CT, or as a second-line alternative to CT for re-evaluation after neo-adjuvant therapy in patients with resectable or borderline resectable disease according to the NCCN classification. However, MRI is increasingly performed routinely in some centers, both at diagnosis and at re-evaluation after neo-adjuvant therapy. The question of which imaging modality between CT and multiparametric MRI is the most reproducible in terms of tumor size measurement becomes important, especially in the evaluation of the response to neoadjuvant therapy. A few studies have investigated the interobserver variability of tumor size measurement in CT versus MRI in the context of radiotherapy management for the delineation of an irradiation field, but to date investigators have not found any study evaluating the interobserver variability of tumor size measurement using RECIST criteria before and after neoadjuvant treatment for pancreatic adenocarcinoma.
The purpose of this study is to prospectively determine the effects of administering proton pump inhibitors (PPIs) following pancreaticoduodenectomy on postoperative outcomes. The findings of this study will help in avoiding the widespread use of PPIs during the immediate postoperative period following pancreatic surgery.
This is a randomized phase 1 clinical trial to evaluate the safety of an optimized neoantigen synthetic long peptide (SLP) vaccines in pancreatic cancer patients following neoadjuvant chemotherapy. The neoantigen SLP vaccines will incorporate prioritized neoantigens and will be co-administered with poly-ICLC. Patients will be randomized to one of two arms: Arm 1 (neoantigen vaccine following neoadjuvant chemotherapy and surgery) or Arm 2 (neoantigen vaccine following neoadjuvant chemotherapy in the window prior to surgery). Those who are ineligible for vaccine administration including those whose disease progresses or recurs during neoadjuvant chemo or who are otherwise unable to complete surgical resection but who had a personalized neoantigen vaccine manufactured, or significant progress has been made as determined by treating physician, are permitted to receive vaccine injections on study.
This is a first-in-human, Phase 1/2 open-label, multicenter, dose-escalation, safety, pharmacokinetics (PK), and biomarker study of CBX-12 in subjects with advanced or metastatic refractory solid tumors.
Perioperative immunologic signatures can predict the risk of postoperative complications. The results will be puplished as two smanuscripts. The manuscript will focus on preoperative immunologisk data,the second manuscript will include both pre- and postoperative data.
This study aims to establish a prospective cohort of developing pancreas cancer and surveillance MRI protocol. With the focused surveillance protocol, we perform surveillance for pancreas cancer for five years to estimate the risk of pancreas cancer and the clinical feasibility of the surveillance MRI.
Evaluation of psychological impact of patients after pancreatectomy because of cancer diagnosis. Patients will be evaluated with questionnaires after and before intervention. 3 control groups will be used to compare de psychological impact.
A multi-center, open-label phase I/II study to to determine the safety and tolerability of Azacitidine and/or Romidepsin in combination with nab-Paclitaxel/Gemcitabine in patients with advanced pancreatic ductal adenocarcinoma (PDAC) (Part 1), followed by sequential immune targeting with programmed death-ligand (PD-L)1 blockade in combination with low-dose Lenalidomide (Part 2) in patients with controlled disease after 3 cycles (Part 1).
This study evaluated the feasibility and reliability of PDAC molecular subtyping on tissue core biopsies samples acquired under EUS guidance. Moreover, this study will assess the impact of molecular subtypes assessed on EUS-FNB samples in patients with resectable and unresectable (locally advanced, advanced, and metastatic) PDAC undergoing chemotherapy on treatment response and survival and the utility in monitoring disease response to therapy and early occurrence of disease relapse using the TaqMan RNA assay in serum
The aim of this study is to validate both retrospectively and prospectively a newly proposed scoring system for perineural and vascular invasion in pancreatic ductal cancer and correlate it with disease free survival, early recurrence, site of recurrence, overall survival and neoadjuvant treatment.
