NCT ID: NCT06331988 Recruiting - Colorectal Cancer Clinical Trials

Microbiome, Immune-system and Tumor Interaction in Colorectal Cancer

MITICO
Start date: July 21, 2022
Phase:
Study type: Observational

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 therefore the need to have more precise information regarding risk factors not only clinical but above all biomolecular on which 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.

Open Pilot Trial of a Mind-Body Sexual Well-Being Intervention for Female GI Cancer Survivors

Start date: April 2024
Phase: N/A
Study type: Interventional

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.

Survival Benefit of Primary Tumour Resection Compared to Systemic Therapy Alone in Stage IV Colorectal Cancer Patients

SurvSysT
Start date: January 1, 2012
Phase:
Study type: Observational

About 20-25 percent of all colorectal cancer patients are diagnosed with International Union Against Cancer (UICC) stage IV disease. The benefit of primary tumor resection in the palliative context is therefore of high concern. However, empirical evidence from randomized and observational studies is inconsistent. The objective of the present study is to compare the survival of palliative stage IV colorectal cancer patients selected for primary tumor resection and systemic treatment (PTR+SYST) to patients with systemic treatment only (SYST).

Dyadic Intervention for Psychological Distress of Patients With Colorectal Cancer and Their Spouses

Start date: April 1, 2024
Phase: N/A
Study type: Interventional

The overall aim of the study is to evaluate the preliminary effect and feasibility of a dyadic intervention on mutuality, psychological strengths (i.e., illness cognition and dyadic coping), psychological distress, and QoL outcomes of patients with colorectal cancer and spouses. The colorectal cancer couples will be randomly allocated to the intervention group to receive a 6-week dyadic intervention, or to the control group to receive the usual care provided by the clinical team in the hospital.

NCT ID: NCT06324409 Not yet recruiting - Cancer Colorectal Clinical Trials

ImmigrantScreen Telephone Reminder Trial in Colorectal Cancer Screening

Start date: March 22, 2024
Phase: N/A
Study type: Interventional

The goal of this randomized trial is to test the effect of a reminder telephone call in the official native language in the country where the invitee is born, in addition to the reminder letter in Norwegian on participation in the National Colorectal Cancer Screening Program in Pakistani and Somalian immigrants, compared to the reminder letter in Norwegian only. The main question it aims to answer is: •Does a reminder telephone call in the language of origin increase participation in colorectal cancer screening in Pakistani and Somalian immigrants in Norway? Participants in this trial are individuals with Pakistan or Somalia as their country of birth invited to the National Colorectal Cancer Screening Program, who have not participated by mailing a faecal sample to the screening laboratory. In the intervention group, the participants will be called in the official language in their country of origin, to inform about colorectal cancer screening, in addition to the reminder letter in Norwegian language sent to all non-participants. Participants in the comparison group will only be sent the reminder letter in Norwegian language. The researchers will compare differences in the participation rate in the National Colorectal Cancer Screening Program between the intervention and comparison groups.

Diagnostic Value of Endocytoscopy for Colorectal Lesions

Start date: March 2024
Phase:
Study type: Observational

Colorectal cancer (CRC) is the third most common malignancy and the second leading cause of cancer-related death worldwide. Colonoscopy is considered the preferred method of screening for colorectal cancer, and resection of colorectal lesions can significantly reduce the incidence and mortality of colorectal cancer. In order to improve the qualitative and quantitative diagnosis of colorectal lesions, many endoscopic techniques, such as image-enhanced endoscopy (IEE), including narrowband imaging (NBI), magnifying endoscopy, pigment endoscopy, confocal laser endoscopy, and endocytoscopy (EC) are applied clinically. The application of EC is intended to achieve the purpose of real-time histopathological endoscopic diagnosis without biopsy. Several studies have shown that EC is effective in identifying the nature of colorectal lesions and judging the depth of invasion in CRC. Based on the endoscopic diagnosis, the endoscopist can determine the treatment plan for the colorectal lesions. The latest EC is an integrated endoscope with a contact light microscopy system with a maximum magnification of 520 x. EC may demonstrate the atypical of gland structure and cells after staining (EC staining mode, along with the use of the EC-NBI mode. The endoscopic diagnosis of the EC staining mode is based on the EC classification (EC-C), used to predict the histopathological diagnosis of colorectal lesions. A prospective randomized trial showed that the diagnostic accuracy was 94.1% by EC-C. However, the diagnostic value of EC-C depends on the operator and may be influenced by the quality of the staining. Meanwhile, the high-quality staining process is time-consuming and tedious. Therefore, EC-NBI seems to be the first choice for EC diagnosis with the advantages of convenient operation and efficient diagnosis. EC-NBI can display the super-amplified surface microvessels of the lesion and provide pathological prediction according to the vessel classification (EC-V). EC-V achieved 99% diagnostic accuracy for hyperplastic polyps and 88.6% for invasive carcinoma. In EC examination, the investigators usually use EC-NBI and EC staining successively to diagnose colorectal lesions, which is believed to improve the diagnostic performance. However, the diagnostic value of increasing EC-staining after EC-NBI examination for predicting the pathological nature of colorectal lesions is still unclear. Therefore, this retrospective study aimed to evaluate the diagnostic value of two different modalities of cell endoscopy for colorectal lesions and to clarify whether additional EC staining after EC-NBI could improve the diagnostic performance of predicting the pathological diagnosis of colorectal lesions. In the study, the investigators collect clinical information of colorectal lesions which were diagnosed by endoscopic diagnosis (including EC-NBI and EC-staining) and pathological diagnosis. Then, the investigators calculate the accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and high confidence diagnosis rate of EC-C and EC-V classification, respectively. Inter-and intra-observer agreement in the diagnosis of EC-C and EC-V will be calculated.
