Filter by:According to current clinical guidelines adjuvant treatment in colon cancer is not recommended in patients with stage I and IIA, and in patients with high risk factors (IIB) adjuvant treatment has not shown a clear benefit in recurrence or survival. However, more than 20% of these patients have recurrence. This high percentage raises the possible understaging of current methods, so in recent years different methods have been developed in order to obtain a correct staging that have allowed a greater detection of micrometastasis (less than 2mm). The performance of the detection technique of the sentinel node in colon cancer allows us to perform this study in 1-3 lymph nodes, so that performing in all the nodes removed in a piece would be imposible in daily clinical practice for time, personnel and economic resources needed to do it. This technique achieves between 5-15% of overstaging which means that in stages I and IIA can lead to a change in the indication of adjuvant treatment. Despite this, the influence of ganglion micrometastases on survival is still controversial. This leads to consider other factors that may influence tumor aggressiveness, such as an increase in angiogenesis that allows the viability of implants less than 2mm. Therefore, we propose that elevated levels of VEGF (angiogenesis marker) in patients with sentinel lymph node micrometastases can lead to a worse prognosis. Based on these premises, the aim of the study is to assess the correlation between the levels of serum and tumor VEGF-A and VEGF-C (markers of angiogenesis and lymphangiogenesis) and the evolution of the disease in patients with lymph node micrometastases.
This study aims to identify the optimal method to recognize, risk stratify, and provide follow-up care for individuals at risk of hereditary cancer. The study team will conduct a Hybrid Type II comparative effectiveness-implementation trial, with a mixed methods component and process/formative evaluations for stakeholder engagement. The study team will evaluate three methods for identifying and risk-stratifying individuals at risk of hereditary cancer and providing post-risk stratification longitudinal care.
Severe muscle loss in patients with cancer has been associated with increased physical disability, extended hospitalization, infectious and noninfectious complications, increased risk of severe toxicity during cancer treatment, poor quality of life and shortened survival. Adequate protein is key to sustain muscle mass and overall health. However, current nutritional recommendations are not specific or evidence-based. The aim of this project is to determine the protein needs of patients with colorectal or breast cancer. Protein needs will be determined using a novel, non-invasive approach. Our results will inform nutritional recommendations and guidelines with the ultimate goal of improving outcomes for people with cancer.
The primary objective of this sub-study, 2019-01B, is to collect blood specimens for research use in the development and validation of a blood-based test for colorectal cancer (CRC).
The primary objective of this study is to assess the sensitivity for colorectal cancer (CRC) and specificity of the mt-sDNA 2.0 test.
The ECLIPSE (Evaluation of the ctDNA LUNAR test in an Average Patient Screening Episode) study is a prospective, observational multi-site study without randomization. The primary objective of the study is to evaluate the performance characteristics of a blood-based ctDNA LUNAR-2 test to detect colorectal cancer in a screen-relevant, average risk population.
At Zealand University Hospital, Denmark, the investigators will examine the immune function of patients with colorectal cancer before and after tumor resection. The immune function will be assessed with functional profiling of the immune function (TruCulture®) The study aims to describe alterations in the perioperative immune response to surgery. The generatied knowledge will lead to better under standing of perioperative pathophysiology.
The purpose of this study is to learn if combination of the two drugs regorafenib and nivolumab is an effective treatment for pMMR - MSS colorectal cancer, a special type of cancer of the colon or rectum (pMMR stands for proficient Mismatch Repair; MSS stands for Microsatellite Stable) and whether it is safe for patients. Regorafenib works by blocking several different proteins involved in tumor growth. Nivolumab is an immunotherapy drug encouraging the body's own immune system to attack cancer cells. Both drugs have been approved, but not for how they are being used as combination therapy in this study. Brand name of regorafenib is Stivarga; brand name of nivolumab is Opdivo.
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.
AlfaOmega has been designed to streamline the study of the co-evolutionary landscape between tumor and host cells in a cohort of CRC patients, with the aim of understanding how their outcomes can be significantly improved (e.g. reduction of their chance of recurrence and survival improval). This clinical resource for integrative clinical data and sample collection will allow the molecular story-telling of CRC metastatic spread along time and space and the selection of appropriate patients for experimentally-driven trials.
