Filter by:Assessment of the efficacy and safety of Regorafenib and Avelumab in patients with advanced or metastatic solid tumors (ten cohorts), once the Recommanded Phase II Dose (RP2D) has been determined (phase I trial). Assessement of the efficacy and safety of a low-dose of regorafenib (80mg/day) with avelumab in patients with advanced or metastatic colorectal tumors.
This trial will compare the effects of a culturally targeted intervention designed to assist participants to identify and overcome individual barriers to colorectal cancer (CRC) and to promote CRC screenings using motivational interviewing (Ml) delivered by a lay health advisor (LHA) compared to the current standard-of-care (distribution of a brochure describing CRC screening services offered by the hospital) on CRC screening compliance.
The purpose of this study is to collect prospective observational data regarding patients with diagnosed Familial Adenomatous Polyposis (FAP) undergoing cold snare polypectomy for duodenal adenomas
The main objective of this pilot study is to implement an awareness campaign for colorectal cancer screening in the workplace, in partnership with the staff of the occupational health service of one of the largest companies in Maine-Loire , and to evaluate the impact of this action on the participation rate of colorectal cancer screening among employees.
Patients with Stage IV obstructing colorectal cancer and unresectable liver metastses, with general and local conditions not a risk for coliorectal resection, will be randomized to have either endoscopic stenting or colorectal resection
Fluorouracil combined with oxaliplatin are routinely recommended to patients with pathological stage III (p-stage III) colorectal cancer, leading to significant improvement of 5-year disease-free survival and overall survival (approximately 3.4% -4.2%) by by international guidelines such as the National Cancer Comprehensive Network. The Considerable proportion of patients suffer with hand-foot syndrome due to capecitabine as commonly prescribed. Meanwhile as another agent of fluorouracil, tegafur，gimeracil and oteracil potassium (short for TGOP) has been shown with similar effect and less adverse reaction. This study was designed to investigate the short-term and long-term safety and efficacy of TGOP-OX and XELOX regimens in colorectal cancer p-stage III patients who undergo curative surgery and adjuvant chemotherapy, and to explore the compliance and quality of life in patients treated with TGOP-OX regime.
MSI (Microsatellite Instability) colorectal cancer (CRC) show improved survival, are less prone to metastasis and show poor response to chemotherapy (compared to MSS tumors). The underlying reasons for these characteristics are still not understood and no specific therapeutic approach for MSI colon tumours (15% of CRC overall) has yet been developed. The MSI process is oncogenic when it affects DNA repeat sequences that have a functional role, e.g. Small Coding Repeats (SCR). MSI also frequently affects Long Non-Coding Repeats (LNCR) in tumour DNA. In contrast to SCR, only a few LNCR are endowed with biological activity. Consequently, this area has received very little attention. Our group recently identified HSP110 mutant chaperone protein in MSI CRC that was generated by somatic deletion of a LNCR. Of interest, HSP110 mutant (due to exon skipping) have anti-oncogenic properties and the survival of MSI CRC patients receiving chemotherapy is positively associated with HSP110 mutations in tumour DNA. The aim of the current project is to identify additional clinically relevant MSI-associated splicing aberrations due to mutations in LNCR located in splice acceptor sites. The four main steps are as follows: 1. To identify exon/intron sites affected by aberrant splicing events due to MSI in CRC . All RNASeq data will be exploited to identify recurrent splicing aberrations (mostly exon skipping) that occur specifically in MSI colon tumours; 2. To investigate for possible functional links between MSI and any detected aberrant splicing events . All specific aberrant splicing events detected by RNAseq in MSI CRC samples will be first confirmed (quantitative RT-PCR) in order to eliminate false positive cases. For validated exon candidates, the allelic profiles of adjacent intronic LNCR will be analysed (PCR and fluorescence genotyping) in CRC cell lines and primary tumours (MSI and MSS), as well as in matching normal mucosa samples in order to assess their polymorphic status; 3. To identify splicing events and LNCR mutations with clinical relevance in MSI CRC patients . All LNCR with a confirmed role in gene splicing in MSI CRC will be analysed. The clinical relevance of candidate genes will be assessed using multivariate survival regression models for Relapse- Free Survival, with interaction terms (response to chemotherapy); 4. To initiate functional studies on a limited number of clinically relevant, cancer-related genes whose splicing is perturbed in MSI cancer cells, and to develop biological tools to simplify screening in future clinical assays Similar to HSP110, we will focus on 4 or 5 mutant proteins that are promising drug therapeutic targets. Functional assays will be developed to further elucidate their role in the pathophysiology of MSI tumours. We also aim to develop biological tools for these candidate genes, such as the detection of wild-type or mutant proteins by immunohistochemistry.
This study is designed to evaluate the short-term and long-term results after three-port laparoscopic surgery for colorectal cancer（TLSC） compared with conventional laparoscopic surgery for colorectal cancer（CLSC）.
The study is an double blind, randomized, multicenter phase 3 trial. The efficacy analyses are based on 570 Chinese patients with RAS wt mCRC treated with mFOLFOX-6 ± cetuximab. Study treatment continues until disease progression or unacceptable toxicity (ie, not for a fixed number of courses). The primary endpoint of the study is progression-free survival (PFS) time according to RECIST 1.0; key secondary endpoints include overall survival (OS) time, overall response rate (ORR), and safety/tolerability.
The study investigators hypothesize that prophylactic HIPEC is feasible and well tolerated in patients with colorectal cancers with high-risk of developing peritoneal recurrence. The aim of the pilot study is to test the feasibility of performing prophylactic HIPEC for colorectal cancer patients at high-risk of developing peritoneal recurrence in our institution, and determine the morbidity associated with such a procedure. Patients with high-risk of developing peritoneal recurrence are defined as patients with 1. tumours involving the serosa and adjacent viscera (i.e. T4 cancers) 2. krukenburg tumours (i.e. ovarian metastases) 3. perforated tumours 4. positive peritoneal fluid cytology 5. minimal synchronous PC (nodules <1cm in the omentum and/or close to the primary tumour). The study investigators plan to assess feasibility according to 1. The number of patients completing the treatment 2. Time to adjuvant systemic chemotherapy, to evaluate if there is delay to adjuvant treatment Morbidity will be measured according to the Clavien-Dindo Classification, and graded according to low versus high grade morbidity. If prophylactic HIPEC is shown to be feasible, with acceptable morbidity, the investigators aim to carry out a randomized controlled trial to determine the effectiveness of prophylactic HIPEC in preventing the development of peritoneal metastases in patients with colorectal cancer at high risk of peritoneal recurrence.
