Filter by:Colorectal cancer (CRC) is the third most common malignancy worldwide and is often metastatic at diagnosis. Despite progresses in surgical techniques and the introduction of novel chemotherapy regimens, many patients still suffer from a poor prognosis. It is therefore of utmost importance to identify prognostic markers that may improve selection of patients. In recent years several studies demonstrated that preoperative blood tests as platelet count or neuthophil-to-lymphocyte ratio could be prognostic factors in CRC as well as other malignancies. The aim of this study was to evaluate the role of preoperative platelet count (PC) in patients with synchronous colorectal liver metastases.
Recent preclinical studies suggest that combining MEK and MDM2 inhibition synergize to induce apoptosis in RAS/BRAF-mutant and TP53 wild-type CRC models. In vitro, in RKO cell lines (poorly differentiated colon carcinoma cell line resistant to single agent targeting MDM2 and MEK and BRAF inhibition), the MDM2 plus MEK inhibitor combination generated a synergistic increase in apoptotic index. In vivo, in mice harboring human RKO colon tumor xenografts the combination of MDM2 plus MEK inhibition elicited 93% decreases in tumor volume. This trial is to conduct a single-center, Phase 1 dose escalation study of trametinib combined with HDM201 (a HDM2 inhibitor) in patients with advanced/metastatic RAS/RAF mutant and TP53 wt CRC.
The main purpose of this study is to test the safety, tolerable side effects, and determine the highest tolerable dose of the combination of Regorafenib and Nivolumab. Researchers want to find out if this combination of Regorafenib and Nivolumab can help people with metastatic colorectal cancer with mismatch repair (MMR) proficiency.
To compare the sensitivity and specificity estimates of Colvera with that of a commercially available CEA test for detection of recurrent disease in subjects with colorectal cancer that have documented recurrence or no evidence of recurrence by CT.
To compare the effects of three types of perioperative analgesia on the number of circulating tumor cells following radical colorectal cancer surgery. To find correlations with other perioperative factors and clinical/pathological disease characteristics.

This is a translational, multicentre and multinational study. The aim of this study is to identify new patient stratification tools in microsatellite stable RAS mutant metastatic Colorectal Cancer
Liver is the most common site of metastases from colorectal cancer. Neoadjuvant chemotherapy with targeted agents is usually recommended for borderline-resectable liver metastases that are technically difficult to resect for conversion to resectable disease and control of metastatic spread. However, the prognosis of these patients are still poor, and long term disease-free survival over 3 years is rare and <20%. More effective measures to prevent recurrence are needed before or after resection of colorectal liver metastases.
The survey is a retrospective study to evaluate the prognotic value of EGFR expression, KRAS mutations and tumor sideness in patients with metastatic colorectal cancer treated with regorafenib and FOLFIRI as a third- or fourth-line setting.
The purpose of this study is to evaluate the efficacy and safety of the combination of study drugs encorafenib, binimetinib and cetuximab in patients who have BRAF V600 mutant metastatic colorectal cancer and have not received any prior treatment for their metastatic disease.
