Active clinical trials for "Colorectal Neoplasms"

This study collects information to provide a model for how to rapidly adapt and scale-up multilevel interventions through clinic-health plan partnerships to reduce the burden of colorectal cancer (CRC) on the United states population. This study may improve colorectal cancer screening rates, follow-up colonoscopy, and referral to care in rural Medicaid patients.

Elective surgery is the most effective treatment option for colorectal cancer, however it has been recognized to be associated with high morbidity and mortality risks. ERAS (Enhanced Recovery After Surgery) is a preoperative multimodality treatment package, which has been well investigated and proved to be effective in reducing early postoperative morbidity, mortality, length of hospital stay and hospital costs, as well. Still, a good proportion of patients are not suitable for ERAS program, mainly based on lack of compliance and the impaired physical function before surgery. Trimodal Prehabilitation Program is a recently introduced preoperative preparation (training) program, which addresses improvement of physical, mental and nutritional status of the high risk elective surgery patients. This study aims to investigate the benefit of all efforts of a 4-6-week preoperative preparation program (Prehabilitation) being added to an established ERAS protocol. Additionally the effect of trimodal prehabilitation on gut microbiom diversity and its relation to clinical outcome will be analyzed.

To explore the effect of CBT on psychological status of colorectal cancer patients undergoing chemotherapy. To explore the effect of CBT on immune function of colorectal cancer patients undergoing chemotherapy.

This is a phase 1/2a open label study to evaluate the dose, safety, tolerability and efficacy of an IP α-emitting radionuclide therapy (Radspherin®) in subjects with peritoneal carcinomatosis (PC) from colorectal carcinoma following complete CRS (cytoreduction score CC-0) and HIPEC. The study consists of three different cohorts: Dose escalation cohorts Repeated injection cohorts Expansion cohort

Background: Sweden has a long tradition of organized national population-based screening programs. Participation rates differ between programs and regions, are relatively high in some groups, but lower in other. To apply an equity perspective on screening, it is desired that individuals make an informed decision on knowledge rather than ignorance, misconceptions, or fear. Decision Aids (DAs) are set to deliver information about different health care options and to help individuals make visible values connected to the options available. DAs are not meant to guide individuals to choose one option over the another. The advantage of an individual Decision Aid (iDA) is that individuals gain knowledge on cancer and screening entering one webpage with possibility to communicate with health professionals and thereafter make their decision regarding participate. The primary objective is therefore to develop and implement a web-based iDA for individuals invited to cancer screening in Sweden. The secondary objective is to evaluate the implemented web-based iDA. Methods: This study has an evaluative approach with both a process-, an implementation and an outcome evaluation. Multiple methods will be used including patient reported data, focus group discussions and individual interviews using the think aloud technique. The project is based on the framework from The International Patient Decision Aid Standards (IPDAS) and the proposed model development process for DAs as presented by Coulter et al. Individuals aged 23-74, including women aged (the cervical- and breast- and bowel cancer screening module) and men aged (the bowel cancer screening module), will be included in the developmental process. Efforts will be made to recruit participants with disabilities, who live outside society and who are foreign born. Discussion: To the best of our knowledge the present study is the first aiming at developing an iDA for usage in Swedish context, The iDA is intended to contribute so that individuals invited to screening base their decision on knowledge and with a clear picture of their values and preferences, rather than ignorance, misconceptions, or fear. Furthermore, the iDA is expected to increase knowledge and raise awareness in general about cancer and cancer screening in society.

Artificial intelligence is a promising tool that may have a role in characterizing colon epithelial lesions (CADx), helping to get a reliable optical diagnosis regardless of the endoscopist experience. Performances of the different CADx systems are variable but it seems that, in most cases, high accuracy and sensitivities are achieved. However, these CADx systems have been developed and validated using still pictures or videos, and a real-world accurate test is lacking. No clinical trials have tested this technology in clinical practice and, therefore, performance in real colonoscopies, practical problems, applicability, and cost are unknown.

This study aim to determine if a different surgical technique could result in a lower anastomotic leak rate. The two techniques are equally used around the world and well described by the international literature but this is the first study that compare the two techniques.

Nowadays, colonoscopy is considered the gold standard for the detection of lesions in the colorectal mucosa. However, around 25% of polyps may be missed during the conventional colonoscopy. Based on this, new technological tools aimed to improve the quality of the procedures, diminishing the technical and operator-related factors associated with the missed lesions. These tools use artificial intelligence (AI), a computer system able to perform human tasks after a previous training process from a large dataset. The DiscoveryTM AI-assisted polyp detector (Pentax Medical, Hoya Group, Tokyo, Japan) is a newly developed detection system based on AI. It was designed to alert and direct the attention to potential mucosal lesions. According to its remarkable features, it may increase the polyp and adenoma detection rates (PDR and ADR, respectively) and decrease the adenoma miss rate (AMR). Based on the above, the investigators aim to assess the real-world effectiveness of the DiscoveryTM AI-assisted polyp detector system in clinical practice and compare the results between expert (seniors) and non-expert (juniors) endoscopists.

Colorectal cancer tissue sections were obtained according to the inclusion criteria. The formalin was used to immersed all cancer specimens. And tissues were cut to 5 μm thickness and placed on glass slides before staining. Endogenous peroxidase activity was inhibited and blocked by de-paraffinizing, rehydrating, and using 5% bovine serum albumin at 37ºC for 30 min. The treated sections were incubated with anti-FOS (promab 30360) at 4ºC overnight and washed three times with PBS. After that, it is required that incubation with secondary anti-peroxidation sunflower at 37ºC for 30 minutes. After washing three times again with PBS, the sections were developed in diaminobenzidine and microscopic images were made by light microscopy.

Mucositis is a common and clinically significant side effect of both anticancer chemotherapy and radiation therapy that can affect any portion of the gastrointestinal tract. Not only associated with an adverse symptom profile, but also it may limit patients' ability to tolerate treatment if not adequately prevented and managed. Moreover, it may be associated with secondary local and systemic infection and poor health outcomes, and generates additional use of healthcare resources resulting in additional costs. Based on study of 38 patients of mean age sixty-one years old diagnosed with colorectal carcinoma were included to evaluate gastrointestinal adverse effect with different schedules of FOLFOX. Incidence of oral mucositis with FOLFOX-4 Is 76%, FOLFOX-6 is 62%, mFOLFOX-6 is 79% and FOLFOX-7 is 93% Chemotherapy-induced mucositis is commonly described as a five-phase sequence: initiation (0-2 days),upregulation and activation of messengers (2-3 days), signal amplification (2-5 days), ulceration with inflammation (5-14 days) and healing (14-21 days) According to the model introduced by some studies the primary inducer involved in unleashing mucosal injury upon chemotherapy is the production of reactive oxygen species (ROS), leading to tissue inflammation and mucositis induction. Inflammatory signaling pathways are upregulated during high reactive oxygen species states which further contribute to cytotoxicity. leading to the third step in the oral mucositis pathway. In this inflammatory phase, cytokines including Tissue Necrosis Factor alpha (TNF-α), prostaglandins, Nuclear factor Kappa β (NF-кβ), and interleukin (IL) 1β are released. The cytotoxic effects of chemotherapy, inflammation, and reactive oxygen species-mediated DNA damage result in gradual apoptosis of mucosal epithelial cells. Ulcerative sites become relatively neutropenic which predisposes them to bacterial and yeast infections. These bacterial toxins further simulate the underlying inflammatory state through release of additional cytokines. It is necessary to emphasize that oral mucositis is frequently documented only in its advanced phases owing to the requirements for clinical therapy and assistance. Therefore, the search for new active ingredients that could be used in the prevention (and even treatment) of oral and intestinal mucositis is of utmost importance.
