Colorectal cancer (CRC) once predominantly affected older individuals, but in recent years has witnessed a progressive increase in incidence among young adults. Once rare, early-onset colorectal cancer (EOCRC, that is, a CRC diagnosed before the age of 50) now constitutes 10-15% of all newly diagnosed CRC cases and it stands as the first cause of cancer-related death in young men and the second for young women. This study aims to detect EOCRC with a non-invasive test, using a blood-based molecular assay based on microRNA (ribonucleic acid)
Colorectal cancer (CRC) is one of the leading causes of death in Croatia. An average of 3600 cases are diagnosed and an average of 2100 people die from the disease every year. Since 2007, Croatia has invited every man and woman aged 50-74 to participate in the home testing screening programme every two years. Currently only around 36% of the invited request the test-kit and 25% complete the home testing procedure, far below the target of 40-60%. The Croatian Institute of Public Health with technical support from World Health Organization (WHO) Regional Office for Europe is undertaking a mixed-methods research study with the aim to increase the completion of colorectal cancer home testing and improve our knowledge of the barriers and drivers to do so. The study has a quantitative and a qualitative component: 1. Quantitative: testing the introduction of a reminder letter to encourage people to respond to the initial invite to participate in the CRC home test program and test which elements of a reminder letter improve response rates. The quantitative component consists of a four-arm reminder letter randomized controlled trial (RCT) comparing no letter, standard letter, behaviorally informed letter, and behaviorally informed letter sent with a home testing kit to investigate the effectiveness of reminders in increasing uptake of home-testing for colorectal cancer. Recruitment and data collection for the reminder letter trial will be conducted utilizing the routine screening process and routinely collected screening data. 2. Qualitative: conducting in-depth interviews with people from the target population who did or did not respond to the CRC invite letter and reminder to better understand the barriers and drivers to participation. The qualitative component consists of 24 in-depth interviews (IDIs) conducted with members of the target population to identify barriers and drivers to completing colorectal cancer screening home-testing. Data collection for IDIs will be face-to-face, using discussion guides, and will be audio recorded. The audio-recordings will then be analyzed using a rapid analysis approach based on by the modified Capability-Opportunity-Motivation-Behavior (COM-B) framework.
The goal of this study is to test a new PET imaging agent in patients with solid tumors. This tracer is made of a radioactively-labeled monoclonal antibody MNPR-101, and can show where tumors are present in the body using a PET-scan. The investigators will investigate if the new imaging agent correctly shows all tumor lesions. In the future, this method may be useful to help predict who will benefit from certain therapies. Participants will be injected with the radioactive tracer once. After injection, participants will undergo 3 PET-scans. Each PET-scan will take a maximum of 30 minutes. The PET-scans are on separate days within 10 days after injection of the tracer (e.g., 2 hours after injection plus 3-5 days and 7-10 days after injection). Furthermore, the investigators will take blood samples 6 times (5 mL each). Blood pharmacokinetics (PK) will be measured on Day 1 at 10 min, 1h, 2h, once on Days 3-5, and once on Days 7-10. The amount of radioactivity injected will range between 37-74 MBq (±10%).
Colorectal cancers represent the second leading cause of cancer-related death in the United States Western world. In Italy they represent the second most frequent neoplasm (49,000 cases in 2019). Despite the advancement of surgical techniques and medical therapy programs systemic, it is estimated that approximately 40-50% of colorectal cancers recur after being treated for a limited loco-regional disease. Patients who develop metastases throughout their history clinic have a 5-year overall survival of just over 10%. Adjuvant systemic chemotherapy can reduce the risk of disease recurrence in patients with colorectal adenocarcinomas, however, the standard drugs used to date for this use (fluoropyrimidines and oxaliplatin) have not undergone substantial changes in the last 20 years or so. A crucial point is the need to have more precise information regarding risk factors above all biomolecular to base therapeutic choices. It has now become urgent to overcome the T-tumor N-node M- metastasis (TNM) staging, to have more modern knowledge on the factors capable of impacting significantly on the prognosis, influence the real risk of disease recurrence, Identify new prognostic categories and subcategories, therefore being able to predict the clinical benefit of treatments that can be more targeted, personalized and effective. In this panorama it has developed in recent years an ever-growing literature also regarding the role of bacterial flora intestinal (microbiota) in patients with colorectal cancer. In particular, recent discoveries have highlighted the immunoregulatory role of the microbiota in the anti-tumor response. This study aims of evaluating how the molecular characteristics of the tumor, of the infiltrating immune system cells and of the associated intestinal microbiota correlate with the development of colorectal cancer, its progression and response to treatments.
The primary goal of this protocol is to conduct an open pilot to collect initial quantitative and qualitative feedback on the intervention that the investigators are developing. To do so, the investigators will deliver a newly-developed intervention to up to 2 consecutive groups of female colorectal and anal cancer survivors (n = up to 10 per group, total N = up to 20). Participants will provide feedback regarding intervention acceptability, feasibility, and perceived benefit. To inform plans for ongoing program refinement, the investigators will elicit specific feedback about study assessment tools, recruitment procedures, and group factors. Given the early-stage, open pilot nature of this protocol, the investigators will not set strict criteria to establish feasibility and acceptability but will rather interpret each of these outcomes holistically. Qualitative feedback collected in post-intervention exit interviews will also support understanding of feasibility and acceptability. As a secondary aim, the investigators will explore the preliminary effects of the intervention on psychosocial measures of satisfaction with sexuality and impact of functional limitations, coping abilities, acceptance of body image changes, loneliness, and anticipated stigma. As noted above, the investigators will not set specific criteria to establish preliminary efficacy, nor will they consider statistical significance as an indicator of the study's efficacy for these outcomes. Instead, the investigators will consider pre-post intervention effect sizes to consider the need for refinement of study procedures/measurement in a future larger trial. In future, larger-scale, work, the investigators intend to conduct a larger randomized pilot trial to assess intervention acceptability, feasibility, as well as preliminary efficacy on essential outcomes related to sexual well-being.
The purpose of this study is to determine the safety, tolerability, and recommended dose of ELVN-002 in combination with trastuzumab in participants with advanced-stage HER2-positive tumors and in combination with trastuzumab, and chemotherapy in participants with advanced-stage HER2-positive colorectal cancer and breast cancer.
This study aims to investigate the clinical, socioeconomic, behavioral, genetic, and molecular factors characterizing Early Onset Colorectal Cancer (EOCRC) patients compared with Late Onset Colorectal Cancer (LOCRC) patients
Novel treatment modalities like targeted therapies and Immune checkpoint inhibitors have revolutionised the therapeutic landscape in oncology and hematology, significantly improving outcomes even in clinical contexts in which little improvement had been observed for decades such as metastatic melanoma, lung cancer, and lymphoproliferative neoplasms such as chronic lymphoid leukemia or Hodgkin lymphoma. However, major issues remain unsolved, given the frequent occurrence of primary or secondary resistance and the still incomplete understanding of the physiopathology of adverse events, which represent a major cause of morbidity and treatment interruption and often remain difficult to treat and diagnose. In this complex landscape, identifying the best treatment option for each patient remains challenging. For both targeted therapies and Immune checkpoint inhibitors, several biomarkers have been reported, but their implementation in clinical practice is still uncommon, and most of the decision-making process remains based on purely clinical considerations or constraints dictated by the regulatory bodies. Obstacles to biomarker-driven decision making are manifold and include insufficient understanding of the underlying biology, lack of strong evidence on their predictive power and limited tumor sampling, which may be circumvented by non-invasive techniques such as liquid biopsies.
Tumor recurrence significantly affects survival rates following the local resection of submucosal colorectal cancers (T1 CRC). Despite this, there are currently no reliable biomarkers established to predict recurrence in T1 CRC. This study seeks to improve the prediction of recurrence-free survival in individuals who have survived T1 CRC.
