Filter by: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.
Colorectal cancer (CRC) once predominantly affected older individuals, but in recent years has witnessed a progressive increase in incidence among young adults. Once rare, early-onset colorectal cancer (EOCRC, that is, a CRC diagnosed before the age of 50) now constitutes 10-15% of all newly diagnosed CRC cases and it stands as the first cause of cancer-related death in young men and the second for young women. This study aims to detect EOCRC with a non-invasive test, using a blood-based molecular assay based on microRNA (ribonucleic acid)
Major hepatectomy in patients with colorectal liver metastases (CLM) and post-chemotherapy liver atrophy is associated with increased complications. Whether the performance of parenchymal-sparing hepatectomy (PSH) in those patients can be safer is unknown. The aim of this study was to assess the clinical impact of post-chemotherapy liver atrophy on patients undergoing PSH for CLM. For this purpose, the occurrence of liver atrophy was recorded and then computed against the occurrence of postoperative morbidity and mortality.
To evaluate the safety, immune response, and potential efficacy of combined immune cell therapy in patients with stage 4 colorectal cancer who have failed standard treatment and have unresectable lesions or metastatic lesions.
This is a Phase II, open label, single-arm trial study of adding hydroxychloroquine to encorafenib and cetuximab in patients with metastatic BRAF V600E colon cancer with progression on at least 1 prior line of therapy. We hypothesize that autophagy is a major mechanism of resistance to BRAF inhibition in stage IV BRAF V600E colorectal cancer, and that the addition of hydroxychloroquine to standard encorafenib and cetuximab therapy will help overcome this resistance.
The National Quality Forum has endorsed at least 12 lymph node yield (LNY) as a surgical quality indicator in colorectal cancer (CRC), but the prognostic value of adequate lymphadenectomy has rarely been investigated for CRC patients with distant metastatic disease.
This is an open-label, multicenter, randomized phase 2 study evaluating the efficacy and safety of fruquintinib plus capecitabine versus capecitabine as maintenance therapy for metastatic colorectal cancer after first-line treatment. Patients who have already achieved disease control (including CR/PR and SD) after ≥6 cycles of standard first-line induction treatment, and are still unresectable would be assigned into 2 maintenance treatment groups by randomization in a 1:1 ratio to receive fruquintinib + capecitabine or capecitabine. All patients will be treated until progressive disease, death from any cause, unacceptable toxicity or informed consent withdrawal.
KEYNOTE-177 is currently the only randomized controlled phase III clinical trial evaluating the efficacy and safety of pembrolizumab versus standard chemotherapy combined with targeted first-line therapy for dMMR/MSI-H metastatic colorectal cancer. The study was conducted at 192 centers in 23 countries and enrolled a total of 307 subjects. The results of the study showed that the median PFS of pembrolizumab was 16.5 months, which was double the 8.2 months in the chemotherapy group (HR 0.60; 95% CI: 0.45-0.80; P = 0.0002). In addition, the ORR was 45.1% in the pembrolizumab group and 33.1% in the chemotherapy group, and a higher percentage of patients achieving a complete remission (CR) with pembrolizumab than in the chemotherapy group (13.1% vs. 3.9%). The U.S. FDA approved pembrolizumab in June 2020 for the first-line treatment of MSI-H/dMMR metastatic colorectal cancer. The results of the KEYNOTE-177 study showed that 29% of patients with dMMR/MSI-H metastatic colorectal cancer experienced direct disease progression (PD) after first-line pembrolizumab monotherapy. This may suggest that some dMMR/MSI-H patients have primary resistance to anti-PD-1 monotherapy. In the first-line treatment cohort of the CheckMate 142 study using nivolumab combined with ipilimumab, the proportion of patients with direct PD was 13%, suggesting that the combination of PD-1 inhibitors and anti-CTLA-4 mAb may have help overcome this primary resistance. In addition, in the second-line and above cohort of the CheckMate142 study, 12% of patients receiving nivolumab in combination with ipilimumab experienced PD directly, compared with 26% of patients receiving nivolumab alone. A study published on 《The Lancet Oncolog》 on the efficacy and safety of ipilimumab monotherapy and ipilimumab combined with anti-PD-1 monoclonal antibody in patients with anti-PD-1 monoclonal antibody-resistant melanoma Retrospective study. The study included 355 patients with unresectable metastatic stage III or IV melanoma who received ipilimumab monotherapy after failure of anti-PD-(L)1 monoclonal antibody (n=162), or Ipilimumab combined with anti-PD-1 therapy (n=193). The ORR was 31% in the combination arm, significantly higher than the 13% in the ipilimumab monotherapy arm. In addition, the median OS and PFS of the combination therapy group were 20.4 months and 3.0 months, respectively, which were also significantly higher than those of the single-agent group of 8.8 months and 2.6 months. The aim of this study was to evaluate the objective response rate (ORR) of Cadonilimab, a bispecific anti-PD-1/CTLA-4 antibody, for PD-1/PD-L1 blockade-refractory, microsatellite instability-high (MSI-H) or mismatch repair-deficient (dMMR), advanced colorectal cancer.
The purpose of this study is to evaluate the efficacy of Durvalumab plus Regorafenib versus observation for patients with stage IV colorectal cancer achieving the no evidence of disease state. The NED state can be achieved in any line of treatment and it is defined as: 1. R0 resection for surgery, 2. the complete ablation defect covering the lesion on CT scan for radiofrequency, 3. the erogation of ≥ 60 Gy for stereotactic radiotherapy, 4. complete response to antineoplastic treatments on CT scan. In all these cases CEA and CA 19.9 must be within normal limits at the time of randomization. Participants in this study will receive: Experimental arm: Regorafenib 90 mg d1-21 every 28 days plus Durvalumab 1500 mg every 28 days for 1 year Control arm: Observation (crossover to Experimental arm is allowed in case of relapse) Tumor assessment will be performed every 12 weeks.
The purpose of this work is to verify prospectively what the rate of response after triple chemotherapy with mFOLFIRINOX in patients in IV stage of Colorectal Cancer who have already failed after at least two lines of dual combinations with fluoropyrimidine, oxaliplatin, irinotecan and anti-EGFR if wild-type RAS. Currently at ICESP, patients are frequently re-exposed in third line to double combinations.
