Filter by:GENCONCOR-1 study is translational research aimed to investigate the concordance of the molecular genetic profile of the primary tumor and brain metastases (BM) of colorectal cancer (CRC). The study was conducted by post hoc analysis of pairs of samples of histological material with determination of the mutational status of genes KRAS, NRAS, BRAF, HER2 and MSI.
To observe the PFS of yttrium [90Y] microsphere injection combined with FOLFIRI and bevacizumab in second-line treatment of CRLM.
Following systemic therapy in metastatic colorectal cancer(mCRC),RAS (including KRAS, NRAS and HRAS gene) status may change from a mutant(MT) to a wild-type(WT),a phenomenon known as "NeoRAS WT"mCRC.NeoRAS WT can be detected by longitudinal circulating tumor DNA(ctDNA) analysis.Therefore, this prospective phase II Study was design to explore the detection rate of peripheral blood ctDNA testing for NeoRAS WT and its guiding value for subsequent treatment for mCRC.
Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide. Microsatellite instability or mismatch repair deficiency occurs in 20% of CRC, and is predominantly found in non-metastatic tumors. The success of the CheckMate 142 and KEYNOTE-177 clinical trials has shifted the treatment paradigm of the MSI/dMMR CRC, which has led to the adoption of immune checkpoint inhibitors (ICI) by international treatment standards. However, despite the encouraging effects of ICI, up to 30% of patients are resistant to treatment and exhibit rapid disease progression shortly after starting ICI. On the other hand, around 30% of patients treated with ICI demonstrate prolonged responses to the treatment with a duration of response of over 40 months. Furthermore, for ~10% of patients, treatment with ICI results in pseudo-progression - a phenomenon of a short-term increase followed by the decrease of the tumor volume. Currently, the mechanisms and biomarkers associated with the response or resistance to ICI in MSI-positive CRC are largely unknown. Select studies suggest that BRAF mutations (specifically, BRAF p.V600E) might negatively affect the patients' progression-free survival following ICI, however, these data are premature. The primary hypothesis is that the clonal heterogeneity and the evolution of MSI status of MSI-positive CRC will play a role in the development of ICI treatment resistance. The primary objective of the study is to investigate the dynamics of MSI status in serial liquid biopsy samples from patients with MSI-positive tumors receiving ICI.
This study is a single-center, prospective, single-arm exploratory study aimed at evaluating the efficacy and safety of trifluridine/tipiracil in combination with cetuximab in the treatment of third-line and above RAS/BRAF wild-type metastatic colorectal cancer.
The Keynote 117 phase III trial demonstrated the superiority of pembrolizumab (anti-PD1 monoclonal antibody) versus chemotherapy +/- targeted therapy in first-line treatment of dMMR/MSI metastatic colorectal cancer (mCRC). However, primary resistance to pembrolizumab was observed in approximately 20-30% of patients treated in the Keynote 177 study. Therefore, the identification of biomarkers predictive of resistance to immunotherapy for dMMR/MSI mCRC is necessary to better select patients who benefit the most from immunotherapy, and those for whom other therapeutic approaches should be favored.
The aim of this study is to assess the efficacy of 166Ho-TARE followed by maintenance therapy with fluoropyrimidine and anti-EGFR or bevacizumab in liver-limited unresectable colorectal cancer patients, in terms of progression free rate 9- and 8-months for cohort A and B, respectively.
The goal of this clinical trial is to to learn about different combinations of immunotherapy in patients with colorectal cancer whose cancer has spread to their liver and are planning to have surgery to remove tumor metastases from their liver. The main questions it aims to answer are: - whether these combinations of immunotherapy change the tumor microenvironment in the liver - whether these combinations of immunotherapy are safe and effective when used in colorectal cancer with liver metastases Participants will be randomly assigned to one of the following: - Botensilimab and balstilimab - Botensilimab, balstilimab, and AGEN1423 - Botensilimab, balstilimab, and radiation Participants will be asked to come in to receive drug infusions (and radiation, if applicable) before and after their surgical resection. Participants will be followed for up to 2 years.
To evaluate the efficacy and safety of Chemotherapy With XELOX (Oxaliplatin + Capecitabine) and Bevacizumab in Combination With Adebrelimab in First-line Treatment of Microsatellite Stable (MSS) Initially Unresectable Metastatic Colorectal Cancer.
The overall 5-year survival rate for patients with colorectal liver metastases (CRLM) is still less than 20%. Surgery-based local treatment can achieve no evidence of disease (NED) in CRLM patients, but over 60% of patients experience recurrence even after achieving NED. Even with adjuvant therapy for the 6-month perioperative period after achieving NED, the recurrence rate remains high. Fruquintinib is a selective anti-angiogenic inhibitor that may help reduce tumor recurrence and prolong the time to recurrence and metastasis. The Chinese Society of Clinical Oncology (CSCO) guidelines have recommended fruquintinib as a third-line therapy for colorectal cancer. This study aims to evaluate the effectiveness and safety of fruquintinib as a maintenance therapy for patients with advanced colorectal cancer (CRC) who have achieved no evidence of disease (NED) after completing adjuvant chemotherapy.
