Filter by:Patients with the Multiple Endocrine Neoplasia type 1 (MEN1) syndrome are genetically predisposed for developping multiple pancreatic neuro-endocrine tumours (pNET). The management of small (pNET) in both MEN1 and sporadic cases, pose a major clinical challenge. At present, pancreatic surgery is the only curative treatment but it is associated with high morbidity. To reduce the morbidity ascosiated with surgery and thereby potentially improve quality of life for MEN1 patients introduction of less invasive techniques for treatment of pNET is important. High-dose-high precision MR-guided radiotherapy (MRgRT) holds promise as a new less invasive treatment option for pNET. The aim of this study is to assess efficiacy and safety of MRgRT for treatment of pNET in MEN1 patients.
This study aims to further observe and evaluate whether the three-week administration of albumin-bound paclitaxel combined with gemcitabine is equivalent to the four-week administration in the treatment of inoperable locally advanced or metastatic pancreatic cancer
This phase I trial tests the safety, side effects, and best dose of calaspargase pegol-mknl in combination with cobimetinib in treating patients with pancreatic cancer that has spread to nearby tissue or lymph nodes (locally advanced) or has spread to other places in the body (metastatic). Cobimetinib attacks a protein called MEK that has been known to stimulate cells that promote the growth of cancer cells in the body. Calaspargase pegol-mknl is an enzyme that converts the amino acid L-asparagine into aspartic acid and ammonia. Many types of cancer cell rely on the amino acid L-asparagine, and depleting this amino acid with calaspargase pegol-mknl starves cancer cells of this nutrient. Attacking the MEK protein with cobimetinib is thought to further prevent cancer cells from using this amino acid, causing them to die. Giving calaspargase pegol-mknl in combination with cobimetinib may help control the disease in patients with pancreatic cancer.
Gemcitabine and nab-paclitaxel are one standard of care for metastatic pancreatic adenocarcinoma (mPDAC) but the progression free survival (PFS) of the regimen is only 5.5 months. Previous phase II study showed gemcitabine and nab-paclitaxel plus cisplatin had a PFS of 10.1 months in mPDAC. This study will evaluate the efficacy and safety of gemcitabine, nab-paclitaxel plus S-1/LV (GASL) against gemcitabine, nab-paclitaxel plus oxaliplatin (GAP) in patients with mPDAC.
This Phase 1 study will evaluate safety and the immune response to pooled mutant-KRAS peptide vaccine with poly-ICLC adjuvant.
The investigators' goal is to conduct a prospective multicenter study to evaluate the yield and outcomes of screening of pancreas cancer in individuals who are at-risk for pancreatic cancer. We plan to use International Cancer of the Pancreas Screening (CAPS3) Consortium recommendations to standardize study population, screening methodology, and study outcomes.
Pancreatic cancer (PC) is a solid malignancy with a dismal prognosis. It has a 5-year survival rate of approximately 8%. This is due to the usually late diagnosis, to chemoresistance, and to intrinsic biological aggressiveness. Risk factors for PC are smoking, alcohol, chronic pancreatitis, obesity, and diabetes. Recently, research has been dedicated to the identification of a causal connection between certain pathogenic microorganisms, especially of the oral flora, and PC. This would ultimately allow to identify new biomarkers to adopt for early diagnosis, or to create new strategies for prevention. Oral microbiota, periodontal disease and neoplastic risk When referring to "oral microbiota" (OM), about 700 hundreds bacterial species are mentioned, colonizing the oral cavity. A change in the normal flora of the oral cavity is commonly indicated with the term "dysbiosis". The causal connection between oral microbiota, periodontal disease and neoplastic risk is possibly triple. First, it has been found that oral flora substantially differentiates between cancer patients and controls. In particular, the most predominant phyla in cancer patients are Firmicutes and Actinobacteria, whereas Proteobacteria, Fusobacteria, and Bacteroides are more common in healthy controls. This highlights the possibility of a direct causal connection between dysbiosis and neoplastic risk. Second, oral dysbiosis represents the main risk factor of PD that per sé is a risk factor of many cancers. Third, the conditions leading to oral dysbiosis (alcohol, smoking, obesity, diabetes, chronic drugs intake, dietary habits, etc.) are the most well known risk factors either for cancer and oral dysbiosis. The common denominator is always represented by chronic inflammation and migration of microorganisms to distant sites, ultimately promoting neoplastic progression. This tangled net of causal connections sheds light on the potential important role of the oral cavity and PD as independent risk factors for many cancers, and as modifiable elements to reduce the neoplastic risk and to perform prevention(15). Oral microbiota, periodontal disease and pancreatic cancer In 2012, the pioneering study by Farrell et al. showed that bacteria of the OM can discriminate PC patients from healthy subjects. Since then, few other studies have shown that changes of the OM are independent risk factors for PC and that the OM of PC patients differs than controls. The involved bacterial species are many and their role seems to be contrasting on the basis of the study considered. Farrell et al. found that the combined adoption of Neisseria elongata and Streptococcus mitis distinguished PC patients from healthy controls (both showed low levels in PC patients, AUC of combined sensitivity 0.9), and that higher levels of Granulicatella adiacens and Streptococcus Mitis distinguished PC patients from chronic pancreatitis ones. Torres et al. found a higher ratio of Leptotrichia to Porphyromonas in PC patients. Fan et al. reported that Porphyromonas gingivalis, Prevotella intermedia, Alloprevotella and Aggregatibacter actinomycetemcomitans are associated with a higher risk of PC, whereas Fusobacteria and Leptotrichia were associated with a decreased risk. Another study evaluating the diversity of OM in three groups of individuals (PC patients, patients suffering from Intraductal papillary mucinous neoplasms [a pancreatic preneoplastic condition], and healthy controls), excluding current smokers and users of antibiotics, found no differences in the OM, although patients with PC had a higher proportion of Firmicutes compared with Intraductal Papillary Mucinous Neoplasms (IPMNs) and controls. Lastly, a recent study by Gaiser et al. showed that the cystic fluid of patients submitted to surgery for IPMNs contained bacterial species that are commonly found in the oral cavity, including, among the others, Granulicatella adiacens, Fusobacterium nucleatum. These two, in particular, were higher in the cohort of individuals with IPMNs with high-grade dysplasia, indicating a pivotal role in tumorigenesis(19). As regards PD, the first studies demonstrating an association between PD and PC date back to the mid of 2000's, and they were confirmed afterward, even adjusting confounders such as diabetes, pancreatitis, hyperlipemia, smoking or alcohol-related conditions. PD is strictly connected to oral hygiene, that seems to be associated to an increased risk of PC. It is now clear that PD can concur to development of PC in several ways, promoting chronic inflammation, spreading continuously to distant organs (including pancreas) pro-tumorigenic bacteria, or promoting a chronic alteration of the immune function that make the individual more prone to develop a cancer.
It is well known that the prevalence of malnutrition or risk of malnutrition in cancer patients is high, as well as its impact on different parameters such as hospitalization, survival or response to certain treatments. In patients with gastroenteropancreatic (GEP) neuroendocrine tumors (NET), due to their heterogeneity and longer survival, it is expected that the prevalence of malnutrition is probably underdiagnosed, as well as the existence of a negative impact on different parameters (quality of life, survival). So far, the studies carried out on nutrition and NET are very scarce and none has been carried out so far in Spain. Before being able to carry out nutritional intervention studies on these patients, it is necessary to know the reality of the nutritional status of patients with NETs in Spain. The main motivation for the NUTRIGETNE study is to evaluate the epidemiological status of nutrition in NETs in the spanish population. In addition to know the epidemiological picture, it is intended to study the nutritional status from different points of view: analytical, clinical, anthropometric, etc. Besides, the study of nutritional status will allow us to closely monitor the patients who have a higher risk of malnutrition and to propose early interventions for those, as well as the impact of their nutritional status on different parameters: survival, hospitalization, quality of life or responses to the treatments. NUTRIGETNE is a cross-sectional, open and multicenter study in which the nutritional status of patients with GEP NET in Spain will be evaluated.
This is a Phase 1b/2, multi-center, open label umbrella study of patients ≥12 years of age with recurrent, progressive, or refractory melanoma or other solid tumors with alterations in the key proteins of the RAS/RAF/MEK/ERK pathway, referred to as the MAPK pathway.
The past 15 years, using National Health Insurance Service (NHIS) database and K-PaC registry, and to analyze the cost and cost-effectiveness along with the change in survival rate after the emergence of the aforementioned regimens, which is very important for policy decisions such as reimbursement of second-line treatment.
