Filter by:Focus of this project is to evaluate the possible financial benefit resulting from an optimization of surgical outcomes throughout a collaborative and systematic auditing activity.The primary objective of this analysis is to assess the employed resources by National Health System related to surgical activities for primary colorectal cancer during a collaborative and systematic auditing activity in 8 Surgical Units of Emilia-Romagna
This study is a multicenter, dose-escalating phase Ib clinical study to evaluate the safety and tolerability of GB226 in combination with fruquintinib in the treatment of mCRC, evaluate the pharmacokinetic characteristics of GB226 in combined therapy, evaluate immunogenicity of GB226, and explore the antitumor activity of GB226 in combination with fruquintinib in the treatment of mCRC.
The purposes of this study are to collect and store samples including blood, normal and tumor tissue from patients with colorectal cancer or gastric cancer, to collect and store samples including blood and/or normal gastrointestinal tissue (if available) from patients with non-malignant disease (including, but not limited to, inflammatory bowel disease (IBD), gastric ulcer, hemorrhoids or hernia), and to create a database for the collected samples and allow access to relevant clinical information for current and future protocols.
Data of 100 colorectal cancer patients with liver metastases who received stereotactic radiotherapy of Cyberknife or microwave ablation in the multicenter of the research group from June 2019 to May 2021 were collected, as well as follow-up data.To evaluate the clinical efficacy of stereotactic radiotherapy and microwave ablation in liver metastases.In addition, the local control rate and side effects of stereotactic radiotherapy and microwave ablation in the treatment of liver metastases were explored, and the efficacy and safety of different doses of stereotactic radiotherapy were determined.
Acetylsalicylic acid (ASA) seems the ideal colorectal cancer (CRC) chemoprevention agent. Several ongoing trials are testing the effect of ASA as co-therapy in CRC. The mechanisms of action, the appropriate dose and the ideal target population are unknown. The investigators have demonstrated that doses of 100 mg of ASA induce direct and partial but persistent acetylation of the cyclooxygenase (COX) isoenzyme COX-1 in the normal colorectal mucosa. The primary objective is to perform a study of aspirin by using a proteomic assay for comparing platelet COX-1 and CRC mucosal COX-1 after different doses of ASA. Secondary objectives are: the measurement of prostaglandin E2 (PGE2) and phosphorylated S6 protein (p-S6) levels in CRC mucosa, the assessment of indirect biomarker of aspirin action (serum thromboxane B2 (TXB2) and urinary levels of 11-dehydro-TXB2 (TX-M)), the evaluation of systemic biomarkers of inflammatory/tumorigenic COX-2 by assessing urinary levels of major metabolite of PGE2 (PGE-M). Methods: Phase II randomized clinical trial in 60 patients with newly diagnosed CRC in 3 groups of 20 patients receiving 100 or 300 mg/day, or 100 mg/12 hours of enteric-coated ASA for 3±1 weeks, prior to definitive treatment by surgery. Main outcome: Acetylation of COX-1 and COX-2. Eicosanoid levels in target organs. Expected results: Evidence for the current uncertainty about the mechanisms of action and the dose required to obtain the best chemopreventive effect with ASA in CRC. Confirm acetylation of COX as a key biomarker of efficacy with ASA.
This study evaluates the effect and safty of PD-1 monoclonal antibody-activated autologous peripheral blood lymphocyte (PD1-T) combined with XELOX and bevacizumab in the first-line treatment of recurrent and metastatic colorectal cancer. Half of participants receive PD1-T combined with XELOX and bevacizumab, while the other half will receive XELOX and bevacizumab.
In this study the characteristics and alterations of the gut microbiome during chemotherapy for metastasized or irresectable CRC are studied, as well as the relation between the gut microbiome and the effects of chemotherapy.
patients with metastatic colorectal cancer who were initially RAS wild and failed at least 2 lines of chemotherapy will be enrolled. Anti-EGFR must have been given in 1st line. Those who remain RAS-wild upon retesting will receive rechallenge with panitumumab and chemotherapy
The purpose of this clinical research project is to explore potential biomarkers and validate the predictive and prognostic value of molecular signature in colorectal cancer.
Metastatic colorectal cancer is one of the common malignant tumors and the overall prognosis is poor. The introduction of immune-checkpoint inhibition (ICI) has led to a paradigm shift in the treatment of patients with metastatic cancer. Stereotactic body radiation therapy (SBRT) delivers a large dose of radiation to the tumor target with high precision while sparing irradiation of the surrounding normal tissues. It is suggested that SBRT could be the most appropriate radiotherapy modality to be combined with immunotherapy since it induces the expression of a series of cytokines and new tumour-associated antigens (TAAs) and is more likely to cause intense immune response and exert an abscopal effect than conventional radiotherapy. Thus, this study is to explore the use of SBRT in combination with ICI in colorectal cancer patients with oligometastasis, in order to get better local and systemic tumor control and improve progress-free survival (PFS).
