Filter by:Due to dMMR colon cancer patients respond poorly to conventional chemotherapy, but immunotherapy can significantly improve the pCR in this group of patients, this study intends to explore whether neoadjuvant immunotherapy can improve the R0 resection rate with preservation of adjacent organs in T4 colon cancer patients with dMMR.
The aim of this clinical trial is to test whether minimal residual disease (MRD) status detected by circulating tumor DNA (ctDNA) could be used to guide precision therapy of post-surgery in colon cancer. The colon cancers are intended for resectable colon cancer of high-risk stage II and low-risk stage III status. The main questions it aims to answer are: 1. Whether patients with MRD negative status could benefit from deferred adjuvant therapy. 2. Whether patients with MRD positive status need intensive adjuvant therapy. The qualified participants will go through two different randomized groups according to the post-surgery 1-month MRD status. In MRD negative groups, participants will be divided into standard adjuvant therapy groups and deferred adjuvant therapy groups at 1:2 ratios. In MRD positive groups, participants will be divided into standard adjuvant therapy groups and intensive adjuvant therapy groups at 1:2 ratios. All the patients will receive MRD detection every 3 months and radiological evaluation every 6 months up to 3 years, and survival follow-up up to 5 years.
This research study is a randomized controlled trial that will observe changes in microbiome activity, changes in chemotherapy toxicity, and any changes in treatment outcomes between two groups of participants undergoing chemotherapy with either early-stage or metastatic colorectal cancer. The names of the study groups involved in this study are: - Exercise - Waitlist Control
Complete and timely colonoscopy after an abnormal stool-based colorectal cancer screening test results in early detection, cancer prevention, and reduction in mortality, but follow-up in safety-net health systems occurs in less than 50% at 6 months. The proposal will implement multi-level approach consisting of a stepped-wedge clinic-level intervention of team-based best practices co-developed with primary and specialty care, a patient-level technology intervention to provide enhanced instructions and navigation to complete diagnostic colonoscopy, and a mixed methods evaluation to explore multi-level factors contributing to intervention outcomes. Developing a solution to this high-risk and diverse population has the potential to translate to other health systems, support patient self-management, and address other patient conditions.
Background: Recent investigations have suggested that sidedness is associated with the prognosis of colon cancer patients. The role of sidedness in surgical outcome is unclear. The aim of this study was to investigate the different clinical characteristics and associated postoperative outcomes of sidedness in colon cancer. Materials and methods: This is a retrospective study using the multi-institutional, nationally validated database of the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) from 2009 to 2013. Sidedness groups including right sided and left sided colon cancer were created according to the associated diagnosis and procedure codes. Postoperative mortality, morbidity, overall complication, and length of total hospital stay were analyzed after using a propensity score matching method.
Marginal acute inflammation would make reporting the serosal involvement of tumors controversial. We aimed to investigate the clinical significance and explore the prognostic value of MAI for stage II localized colon cancer.
The goal of the study is to determine, using a choice-based approach, what messages (pulled from various online sites) people find more and less persuasive and shareable on the topic of colorectal cancer screening. As a secondary goal, the study is interested how various information behaviors, such as people's self-reported seeking of health information and encountering of health information, demographic variables, individual difference variables, and message exposure associate with their intentions to adhere to recommended colorectal cancer screening guidelines from the National Cancer Institute. The study is interested at differences specifically among Black and White Americans of recommended screening age (45-74).
This study aims to elucidate the effects of neoadjuvant Tislelizumab combined with chemotherapy in locally advanced Microsatellite Stable (MSS) colon cancer.
The purpose of this study is to determine the clinical efficacy, safety, and oncologic outcomes of ileocecal resection (ICR) with D3 lymphadenectomy compared to standard right hemicolectomy(RHC) for cecal cancer.
In general, the European pathological examination method primarily relies on pathologists and does not require the involvement of surgeons. The Japanese pathological evaluation approach, on the other hand, involves the intervention of surgeons, particularly in the extraction of lymph nodes from fresh specimens and the assessment of specimen quality. Given that the Japanese pathological assessment method lacks systematic evaluation and there is currently no literature clearly demonstrating its diagnostic accuracy, the main objective of this study is to verify whether the diagnostic accuracy of the Japanese pathological investigation method is inferior to that of the European pathological evaluation method.
