Colorectal cancer (CRC) is a significant cause of morbidity and mortality worldwide. Its early clinical manifestations are often subtle, leading to late-stage diagnosis in about 30% of cases with distant metastases. Liver metastases are widespread and associated with poor prognosis, especially in terms of response to immunotherapy. Despite advancements in first- and second-line treatments, third-line therapies for advanced CRC remain limited, emphasizing the need for novel strategies. This prospective study evaluates the efficacy of combined therapy involving Sintilimab, Fruquintinib/Regorafenib, and radiotherapy in advanced CRC. The study cohort comprises patients with non-liver metastatic advanced CRC and those with liver metastases, each receiving tailored treatment protocols. The primary objectives are to assess progression-free survival (PFS), overall survival (OS), and treatment response rates. Subgroup analyses will focus on liver metastases to delineate their impact on treatment outcomes. The rationale for this study stems from the intricate interplay between immunotherapy, targeted therapy, and radiotherapy in CRC management. Previous data suggest a negative correlation between liver metastases and immunotherapy efficacy, necessitating a comprehensive approach integrating multiple treatment modalities. Radiotherapy, particularly stereotactic body radiation therapy (SBRT), has shown promise in controlling liver tumors and modulating the tumor microenvironment, potentially enhancing immunotherapy responses. This study aims to provide valuable insights into optimizing third-line and subsequent therapies for advanced CRC by elucidating the efficacy and safety of this combined treatment approach. The findings may pave the way for personalized treatment strategies tailored to individual patient characteristics, ultimately improving clinical outcomes in this challenging disease setting.
This is a prospective, observational cohort study to establish the minimal residual disease (MRD) model for predicting relapse risk and identifying disease recurrence in patients with colorectal adenocarcinoma based on the miRNA platform. Blood miRNA markers will be evaluated. The study will enroll approximately 600 participants, including participants with malignancies or benign diseases, and healthy participants.
Natural orifice specimen extraction surgery (NOSES) has gained widespread recognition among scholars and has gradually been promoted and popularized around the world. However, the development of NOSES is still in the exploratory stage and there is a lack of strong evidence from evidence-based medicine to support its feasibility and safety, which has greatly affected its clinical application and development. Based on this, at the call of Professor Xishan Wang, the Chinese NOSES Alliance conducted a large retrospective clinical study involving multiple centers. By summarizing the NOSES cases of nearly 100 centers in China, the study aims to clarify the current status of NOSES surgery in China. Additionally, a comprehensive analysis and summary was conducted by combining the basic information of NOSES patients, perioperative data, postoperative pathological data, and follow-up information to further demonstrate the safety and feasibility of NOSES in the treatment of colorectal cancer. This study also provides more real and objective evidence-based medicine support for the promotion and development of NOSES surgery.
A single arm, prospective, single center Phase1/2 Dietary intervention trial for subjects diagnosed with colorectal cancer and scheduled for tumor resection more than 21 days from informed consent. Subjects will be provided 21 days of standardized plant-based low fat/ high-fiber meals and complete a food diary up until lunch on the day prior to surgery. Blood samples will be collected at baseline and on the day of surgery. Stool samples will be collected throughout the dietary intervention period at specific timepoints, on the day of surgery, and 30 days post-surgery. Tissue from the tumor resection will be isolated for organoid cultures. Subjects will be followed per standard of care for up to 5 years or disease recurrence, whichever comes first. Subject may be treated for their cancer prior to surgery and/or during the follow-up period.
Based on the interaction between radiation therapy and immunotherapy and the potential potentiation of Probio-M9 for the treatment of ICIs, this study is planned to design an integrated treatment protocol for the first-line treatment of advanced gastrointestinal tumors through the use of macrofractionated radiotherapy as a means of immune activation, combined with the synergistic effect of Probio-M9 microbial agents and PD-1 inhibitors.
The DNA methylation targets in preoperative plasma samples of the subjects will be detected by the multi-gene methylation test (ColonAiQ), and the test accuracy will be evaluated by compared with the clinical diagnosis evidence.
The Enhanced Recovery after Surgery (ERAS) protocol has transformed perioperative care, representing a significant paradigm shift in managing colorectal cancer patients. While the immediate benefits of Enhanced Recovery After Surgery (ERAS) in expediting postoperative recovery are well-documented and widely acknowledged, it is essential to investigate its long-term implications, particularly its influence on survival rates. The aim of this study will be to analyse the impact of compliance with the ERAS protocol on long- term outcomes after laparoscopic colorectal resection.
In this study, we aimed to develop, internally and temporally validate the machine learning models to help screen YOCRC bansed on the retrospective extracted Electronic Medical Records (EMR) data.
This study aims to develop a highly sensitive, specific, and cost-effective blood assay for early detection of colorectal adenomas and cancer, using advanced machine learning and state-of-the-art biological analyses.
