Filter by:The purpose of this study is to study the way radioembolization works by collecting biopsy samples of participants' tumors after the procedure. This research may improve the way that radioembolization is performed, which could help people whose cancer has spread to the liver. The research may also provide information about how tumors respond to radioembolization.
A Phase 1/2 Open-label, Multi-center Study of the Safety, Pharmacokinetics, and Anti-tumor Activity of LYT-200 Alone and in Combination with Chemotherapy or Tislelizumab in Patients with Metastatic Solid Tumors
Retrospective multicentre study. All patients with a diagnosis of Crohn's disease (CD) and operated for colorectal cancer (CRC) between 01/01/2010 and 01/01/2020 will be included in the dataset. Data will include preoperative, intraoperative and postoperative variables, with long term follow up when feasible. The study will focus on a comparison between patients treated with total proctocolectomy (TPC) and patients treated with subtotal colectomy (STC) or segmental resection (SR). Primary endpoints will be oncologic outcomes, postoperative morbidity and mortality. Secondary endpoints include quality of life (QoL).
To determine the efficacy and safety of surufatinib, toripalimab and chemotherapy in second-line RAS/BRAF mutant and MSS colorectal cancer
This research is designed to determine if experimental treatment with PARP inhibitor, AZD5305, alone, or in combination with anti-cancer agents is safe, tolerable, and has anti-cancer activity in patients with advanced solid tumors.
ARGONAUT is a longitudinal, prospective, observational study that will enroll up to 5,000 advanced-stage cancer patients of diverse racial backgrounds to collect data used to develop precision microbiome medicines and for the identification of clinically actionable cancer-specific biomarkers to guide therapeutic decisions. Four types of solid tumor cancers will be profiled including non-small cell lung cancer (NSCLC), triple negative breast cancer (TNBC), colorectal cancer (CRC) and pancreatic cancer. Healthy control subjects without a cancer diagnosis will also be studied, comprised of individuals at high risk for CRC and healthy individuals at low risk for CRC. Risk assessment will be based on family history or past neoplastic findings during CRC screening. Data collected from this study will be used to develop the most effective new therapies, via microbiome optimization, all to the benefit of patients and the physicians treating them. Stool and blood samples will be collected longitudinally and analyzed to determine the impact of gut microbiome composition and function on the immune system and efficacy of the treatment. Currently enrolling the CRC, high risk, and low risk cohorts. Subjects who meet the entry criteria will provide up to 5 samples each of blood and stool over a 2-year period. Approximately 10%-20% of the subjects will provide colon tissue samples, either from research biopsies during Standard of Care (SOC) screening colonoscopy or retained surgical tissue from colectomy. Electronic health records will be obtained at various times for up to 8 years, to collect tumor imaging results and any other updated medical data, with no additional samples collected. In select cases, stool and blood samples will be collected beyond 2 years.
Introduction It has been shown that some quality indicators in endoscopy can be improved through educational interventions. There are marked differences in the proportion of incomplete polypectomies among endoscopists. The effectiveness of measures to improve it has not been evaluated. Objective The main objective is to evaluate whether a training intervention or the notification of the individual proportion of incomplete polypectomies (those in which post-polypectomy biopsies of the resection margin show tissue other than normal mucosa) can improve this proportion. As secondary objectives, we will compare the proportion of fragmented polypectomies and adverse events. We will evaluate the factors associated with incomplete excision or failed cold polypectomy, as well as the individual evolution of the participants. Methods Non-pharmacological clinical trial involving endoscopists with> 1 year of experience and patients scheduled for colonoscopy. After each polypectomy, 2 additional biopsies will be taken and evaluated centrally by a blind pathologist. In a first phase, the basal rate of the participants will be evaluated. After it, the endoscopists will receive a course on endoscopic polypectomy and the other their rate of complete resection. The number of polyps required will vary depending on the number of endoscopists The primary objective will be compared using logistic regression models based on generalized estimating equations (GEE), taking into account the within-subject correlation.
Multicentric prospective and observational study to assess the 5-year overall survival in a cohort of patients with unresectable liver-only colorectal metastases, well controlled by chemotherapy prior to liver transplantation.
An increasing number of patients with metastatic colorectal cancer (mCRC) are able to receive 3 or more lines of therapy. In this setting, can be recognize treatments such as regorafenib (an oral multikinase inhibitor), trifluridine/tipiracil hydrochloride (TAS-102), an antineoplastic nucleoside analogue, and antibodies anti-epidermal growth factor receptor (EGFR) in patients with RAS wild-type tumors (if no prior exposure to antibodies). Maintaining quality of life is an essential goal for third- and later-line treatments for patients. The anti-programmed cell death protein 1 (anti-PD-1) immune checkpoint inhibitors, pembrolizumab and nivolumab, were approved in the US by the FDA in 2017, and the combination nivolumab plus ipilimumab (anti CTLA-4) was recently approved by the FDA in 2018, all in the second and later-line setting for patients with microsatellite instability-high (MSI-H) or deficient DNA mismatch repair mCRC whose disease has progressed despite treatment with fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy. At present, these agents are not approved in Europe for mCRC patients with MSI-H. Clinical trial results and scientific data supported evidence that immunotherapies provide benefit but are limited to the small proportion (< 5%) of patients with MSI-H tumors, in whom they are highly effective. Therefore, patients with MSI-H disease should be referred as expeditiously as possible to receive immune checkpoint inhibitors. The aim the study is to retrospectively collect data of patients treated with immunotherapy in the context of real clinical practice, in order to describe the real impact in terms of clinical outcomes and tolerability of treatment in common clinical practice.
A cross sectional multicenter study (3 centers) to know the participation in decision making and the experience and satisfaction of participants with a positive immunological fecal test (FIT) result in relation to the screening process and the diagnostic-therapeutic process of cancer. We will include 850 participants with a positive FIT result and will classify them by their final diagnosis (false positives of FIT; polyps; colo-rectal cancer). Outcomes of interest will be measured by auto administered questionnaires: collaboRATE, SDM-Q-9, OUT-PATSAT35 and a satisfaction questionnaire developed in a previous study.
