Filter by:The goal of this observational study is to explore whether contrast-enhanced ultrasound (CEUS) can early predict and evaluate the treatment response of first-line chemotherapy in locally advanced and borderline resectable pancreatic cancers. The main questions it aims to answer are: Question 1: What quantitative parameters of CEUS performed before first-line chemotherapy can predict the early treatment response of patients with locally pancreatic cancer?Question 2: Can CEUS reflect early neovascular changes after first-line chemotherapy in pancreatic tumors? Participants will receive CEUS examination carried out by experienced operators before the first cycle of chemotherapy and after 2 treatment cycles.
The goal of the PROPH-ITA Study is to perform genetic testing in family members of pancreatic cancer patients who may have a genetic predisposition. The subjects belong to the Italian Registry of Families At Risk of Pancreatic Cancer (IRFARPC, #NCT04095195). This investigational study will assess the genetic background of subjects with familiarity with pancreatic cancer only. Participants may accept to undergo genetic testing as part of the IRFARPC registry, through a saliva-swab-based 41-gene panel test. Up to 3,000 participants will be enrolled in this study.
This is a single arm study in the treatment of pancreatic ductal adenocarcinoma (PDAC). The investigators propose to test the tolerability of chemotherapy plus endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) using the RF Electrode in patients receiving palliative second or third line therapy for unresectable non-metastatic pancreatic cancer.
Pancreatic cancer is a disease with a very poor prognosis and less than 10% of these patients live beyond 5 years from diagnosis. Further, it is expected to become the second leading cause of death in the coming years. Today, surgery remains the cornerstone in curing this disease, but the addition of chemotherapy is needed to improve survival. The impact of adjuvant treatment has been previously demonstrated and its efficacy is absolute. However, neoadjuvant chemotherapy (pre-surgery) improves the results after surgery (achieving earlier stages and with better prognosis) and would lead to better survival results. Besides, the moment of cancer diagnosis is a moment of special receptivity to change lifestyles ("teachable moment"). Multimodal prehabilitation includes 1) physical exercise; 2) nutritional and 3) psychological support. The potential advantages of prehabilitation during neoadjuvant therapy would be 1) the possibility of achieving a better physical condition to face surgery; 2) fewer postoperative complications; 3) more likely to receive adjuvant treatment after surgery; 4) better physical function at the end of treatments. To date, most studies have focused on lung and prostate cancer, with a high prevalence of men in the series. This strategy has previously been explored, showing that it is safe and feasible, (Loughney et al). We have not identified any study of trimodal prehabilitation during neoadjuvant treatment and none that has integrated motivational strategies to maintain adherence. Patients during chemotherapy have perceived several adverse effects that could limit adherence to the program. In this regard, a review on the motivation and exercise in cancer survivors shows that it is necessary to apply theoretical frameworks to understand cognitive and motivational processes and develop educational interventions. The self-determination theory is one of the motivational theories most applied today to the analysis of factors related to the adoption of healthy lifestyles. Likewise, patients who are motivated are more likely to improve healthy habits and obtain greater adherence to exercise performance. Therefore, we aimed of carrying out an intervention (pilot study) in ten patients to describe the feasibility of a trimodal prehabilitation program in the hospital environment, applying motivational strategies and a mixed-method (face-to-face and online).
"Non-immunogenicity" of PC with high prevalence of immunosuppressive cells and typically a scarcity of tumor-infiltrating effector lymphocytes is considered as one of the reasons for lacking responsiveness to single-agent immunotherapies. Considering the emerging role of the tumor microenvironment, the combination of checkpoint blocking antibodies with immunomodulation of the tumor microenvironment could lead to better responses in tumor historically resistant to radiation and checkpoint blocking antibody approaches as single modalities. For example, the data from the phase 2 study CheckPAC (NCT02866383) showed durable clinical benefit in a small subgroup of patients after adding SBRT of 15 Gy to a combination of nivolumab and ipilimumab (presented at ASCO GI 2022, San Fransisco) in patients with resistant metastatic PC. Furthermore, we have found that the TGFβ-15 immune response is corelated to clinical benefit, supporting the rationale for combining of TGFβ-15 peptide vaccine with CheckPAC strategy (SBRT of 15 in combination with nivolumab and ipilimumab).
The goal of this clinical trial is to analyze if intraperitoneal drainage is necessary following distal pancreatectomy. This study aims to determine whether the omission of routine intraperitoneal drainage in the setting of reinforced staple technology is non-inferior to routine intraperitoneal drainage with respect to a composite post-operative complications of Grade B or C Postoperative pancreatic fistula (POPF), readmission, or organ space surgical site infection following a distal pancreatectomy.
Rationale: Bile salts are potent signalling molecules influencing various metabolic and functional processes. Bile salts exert these functions by activating nuclear (e.g. FXR ) and plasma cell membrane-bound receptors (e.g. TGR5) which are expressed in several tissues (e.g. liver, small intestine, colon, kidney and gallbladder). Bile salts regulate their own biosynthesis by controlling the transcription of the hepatic bile salt synthetic enzyme CYP7A1. Two pathways are involved in the negative feedback control of bile salt synthesis: i) the hepatic FXR-SHP pathway and ii) the ileal FXR-FGF19 pathway. Studies showed that the latter is more prominent in controlling CYP7A1 transcript levels (viz. bile salt synthesis). Thus, bile salts are synthesized in the liver, excreted in bile and expelled by the gallbladder into the proximal intestine (to aid in lipid absorption and digestion) and reabsorbed in the terminal ileum to recycle back to the liver via portal blood. Bile salts reclaimed from the intestinal lumen by the ileocyte, activate FXR. This induces the expression of an enterokine, FGF19, which signals via portal blood to the liver to activate its receptor which initiates downstream signalling to repress bile salt synthesis. The FXR/FGF19 signalling pathway is the subject of the present study. Patients with obstructive cholestasis (=accumulation of bile) caused by malignancies (e.g. pancreatic cancer, cholangiocarcinoma) have a perturbed enterohepatic cycle. Obstructive cholestasis is associated with i) gut barrier dysfunction, ii) endotoxemia, iii) bacterial overgrowth and iv) liver injury. Previous study showed that FGF19 is expressed in the liver of patients with obstructive cholestasis. However, knowledge about the contribution of FGF19 protein by the gut in obstructive cholestasis has thus far been unexplored. Preliminary findings revealed that FGF19 is produced by the portal drained viscera (viz. intestine) of non-cholestatic patients undergoing liver surgery. The inter-organ signalling of FGF19 in an obstructed entero-hepatic cycle has not yet been characterized and likewise the metabolic and other functional effects of inflicted FGF19 signalling during cholestasis have not been clarified. The hypothesis is that the FXR-FGF19 pathway is disturbed in patients with obstructive cholestasis, and this is associated with organ injury and metabolic dysfunction. The investigators postulate that FGF19 is not produced by the terminal ileum under conditions of obstructive cholestatic, but production is shifted to the liver and this affects metabolic processes. The aim of this study is to investigate FGF19 signalling in patients with cholestasis compared to non-cholestatic patients or post-cholestatic patients (drained patients) by calculating fluxes across the portal drained organs. Secondly, the investigators aim to investigate the metabolic and functional consequences (glucose, lipid homeostasis, cholestatic itch, gut barrier function) of a disturbed FXR-FGF19 pathway in humans. This study will provide insights that may lead to potential therapeutic strategies for patients with a disturbed enterohepatic cycle (e.g. cholestatic liver diseases). Study population: Adult (>18 years old) cholestatic (cholestasis group), drained (restored enterohepatic cycle) and non-cholestatic patients (controls, normal enterohepatic circulation) undergoing pancreaticoduodenectomy (Whipple procedure) for hepatopancreaticobiliary malignancies (e.g. pancreatic cancer, cholangiocarcinoma) or liver resection for hepatic malignancies (e.g. cholangiocarcinoma, colorectal liver metastases) are eligible for this study. Study period: inclusion is planned from 1.12.2017 until 1.12.2024
