NCT ID: NCT06251297 Active, not recruiting - Colorectal Cancer Clinical Trials

Feasibility and Benefits of Reflexology in the Prevention of Neuropathy Induced by Oxaliplatin in Colorectal Cancer

FIRENOX
Start date: May 26, 2023
Phase: N/A
Study type: Interventional

The management of colorectal cancer often requires oxaliplatin-based chemotherapy, either as part of curative treatment plans or exclusively in palliative situations. Oxaliplatin therefore plays a key role in the management of colorectal cancer. In addition to its digestive and hematological toxicity, oxaliplatin frequently induces chronic, often limiting, sensitive peripheral neuropathy. Only early discontinuation of oxaliplatin can limit the risk of clinically limiting neurotoxicity (grade ≥ 3). In oncology, managing the side-effects of treatment is an essential objective of supportive care, and is open to a variety of complementary medicines, including reflexology. This technique, derived from traditional Chinese medicine, involves stimulating reflex points on the arch of the foot.

NCT ID: NCT06143644 Active, not recruiting - Colorectal Cancer Clinical Trials

Predictive Value of Postoperative Circulating Tumor DNA Monitoring for Colorectal Cancer Recurrence

Start date: January 15, 2022
Phase:
Study type: Observational

This observational study aims to assess the predictive value of postoperative circulating tumor DNA (ctDNA) monitoring in evaluating the risk of recurrence in stage I-IV colorectal cancer patients. The study involves the collection of blood samples from patients who have undergone surgery for colorectal cancer. Sensitivity-enhanced molecular biology techniques are utilized to detect ctDNA in these samples. The correlation between ctDNA detection and the risk of recurrence is evaluated by analyzing patient follow-up data and clinical information. The findings of this study may contribute to the development of improved postoperative management strategies, such as identifying high-risk individuals and implementing additional treatment measures to reduce the risk of recurrence.

Appendectomy and Colorectal Cancer

Start date: June 1, 2022
Phase:
Study type: Observational

Colorectal cancer (CRC) is one of the most common cancer worldwide. Initiation and progression of CRC involve complex interactions among genetic, epigenetic and environmental factors. Given that hereditary and familial CRC only accounts for 2% to 5% of cases, environmental factors are the key triggers of CRC. Emerging evidence has indicated that gut microbes are an important environmental factor promoting CRC development. Gut dysbiosis has been shown to promote colorectal carcinogenesis in mice. Several individual bacterial species, such as the enterotoxigenic Bacteroides fragilis (ETBF), Fusobacterium nucleatum and Peptostreptococcus anaerobius, could exert carcinogenic effects by inducing direct DNA damage, oxidative damage and activating oncogenic signaling pathways. Recent studies have shown that the appendix plays an important role in maintaining homeostasis and biodiversity of gut microbiome by providing an ideal ecological niche for commensal bacteria and production of immunoglobulin A. Considering the key role of microorganisms in gastrointestinal pathophysiology, absence of appendix may result in disruption of microbiome homeostasis, which could potentially influence the risk of developing CRC. In terms of epidemiological evidence, the association of appendectomy with the risk of CRC development has been controversial, and to date no consensus has been attained. Although gut microorganisms could be a crucial pivot between appendectomy and risk of subsequent CRC development, the direct contribution of appendectomy and the underlying mechanisms are still largely unexplored. In this study, we aim to study 1. the association between appendectomy and colorectal cancer, and 2. the role of appendectomy in CRC risk through causing gut microbial dysbiosis.

NCT ID: NCT06026618 Active, not recruiting - Colorectal Cancer Clinical Trials

Perioperative Management of Preoperative Anemia in Colorectal Cancer

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

Both preoperative anemia (PA) and perioperative blood transfusion can contribute on poorer outcomes after colon cancer surgery. Anemia is known to be associated with a slower recovery after surgery thus often worsening short-term results, and allogenic red blood cells transfusion (ARBT) are known to promote systemic inflammatory response and affect overall and cancer-specific survival. Patient Blood Management (PBM) systems are an evidence-based multimodal approach focused on safe and rational use of blood products, mainly through a proper PA assessment, a minimization of procedural blood loos and strict transfusion policies. Given the high prevalence of PA in patients with colorectal cancer (CRC), and its association with adverse events, it is expected that PBM implementation in said scenario carries a decrease in complications and an improved survival rate. Available literature to date supports preoperative anaemia screening and restrictive transfusion policies, nevertheless barriers exist that limit the expected implementation of PBM systems in colorectal surgery. The present study aims to evaluate feasibility of a PBM pathway implementation in a high-volume CRC Surgery Unit based on completion of anemia screening and treatment before surgery and changes of allogenic products use along the years. The objective is to estimate the impact of a proper preoperative optimization with iron intravenous infusion (IVI) on PA measured from changes Hemoglobin (Hb) levels in comparison to those of non-anemic patients.

An Observational Study Called STAR-T to Learn More About the Sequential Treatment With Regorafenib and TAS-102 in Adults With Metastatic Colorectal Cancer Under Real World Conditions

STAR-T
Start date: April 24, 2023
Phase:
Study type: Observational

This is an observational study using data that has been collected from participants who received their usual treatments. Metastatic colorectal cancer (mCRC) is a cancer of the colon (large bowel) or the rectum (lowest part of the bowel just before the anus) that has spread to other parts of the body. Regorafenib is an anti-cancer drug that blocks several proteins, called enzymes, which are involved in the growth of cancer. The combination of anti-cancer drugs trifluridine and tipiracil is called TAS-102. It prevents cancer cells from growing and multiplying. Both regorafenib and TAS-102 are approved treatments for metastatic colorectal cancer and are available for doctors to prescribe to people with mCRC after previous lines of treatment have been unsuccessful. Regorafenib and TAS-102 work in different ways and impact people differently. People might receive one of these drugs first and followed by the other. The best sequence for taking these drugs is still unclear. Researchers have also found that TAS-102, when taken with another anti-cancer drug called bevacizumab, helps people live longer than when taken alone. To better understand the impact of the sequence of taking regorafenib and TAS-102 (with or without bevacizumab), more knowledge is needed about how these work together in people with mCRC in real world settings. The main purpose of this study is to learn more about the characteristics and impact of treatment in people with mCRC who received regorafenib and TAS-102 (with or without bevacizumab) one after the other. This information will be grouped based on their treatment sequence and age group (less or more than 65 years old). In addition, the researchers want to learn about : - how long participants were treated with regorafenib and TAS-102 taken one after the other in a sequential order, - any treatment for mCRC that the participants received after the sequential treatment, - any treatment received for a condition in which the bone marrow cannot make up enough blood cells (a common side effect of cancer treatment), during the sequential treatment, - if and how often white blood cells that fight infection decreased during the sequential treatment, - the number of hospital or testing facility visits that participants had during the sequential treatment, and - how long did participants live (also called overall survival). The participants in this study had already received regorafenib and TS-102 (with or without bevacizumab) as part of their regular care from their doctors. The data will come from the participants' information stored in an electronic health records database called Flatiron mCRC EDM. Data collected will be from January 2015 to December 2022. Researchers will only look at the health information from adults in the United States of America. In this study, only available data from routine care is collected. No visits or tests will be required as part of this study.
