Filter by:The purpose of this study is evaluate the pharmacokinetics, pharmacodynamics, immunogenicity and anti-tumor effect of of fully human anti - VEGF monoclonal antibody LY00101 and explore the potential prognostic and predictive biomarkers. This study will not take into account the results of molecular-genetic tests of patients enrolled in the study
A randomized controlled trial to examine the effect of 3 mobile telephone text message reminders on followup colonoscopy 120 days after a positive fecal occult blood test among Meuhedet members aged 50-74 who tested positive in 2016.
Two metaanalyses of studies on the prognostic significance of circulating cancer cells in colorectal cancer indicated, that the presence of circulating tumour cells (CTC) in the peripheral blood is the negative prognostic factor. However there is no sufficient evidence that disseminated tumour cells (DTC) in the bone marrow of the colorectal cancer patients influence the prognosis. There is the evidence that right-sided and left- sided cancers may have different biology and different prognosis. Therefore in this study the investigators concentrated on the left colon and rectum locations with the locally advanced cancer being the main area of interest. The aim of this study was to analyse the relation of DTC with the tumor characteristics, cancer progression and survival in left sided colorectal cancer.
The burden of colorectal cancer (CRC) is unequal among various populations within the United States. This inequality is most notable among African Americans, who exhibit the highest CRC mortality of all US populations. This study aims to evaluate a community-based intervention to educate, assess risk, and overcome barriers to screening among African Americans who are 45 years or older with no personal history of CRC, adenomas, or inflammatory bowel disease and have no family history of CRC. Barriers being assessed include: Need for establishing care with primary care physician, need for financial assistance, need for reminder calls, need for transportation, need for appointment coordination, and need for education about colonoscopy preparation and procedure
The purpose of this study is to evaluate the safety, dose, immunogenicity and early clinical activity of GRT-C901 and GRT-R902, a personalized neoantigen cancer vaccine, in combination with nivolumab and ipilimumab, in patients with metastatic non-small cell lung cancer, microsatellite stable colorectal cancer, gastroesophageal adenocarcinoma, and metastatic urothelial cancer.
PD-1(programmed death protein 1)antibody has been to approved in patients with MSI-H/dMMR advanced cancer and has achieved significant efficacy. It is reported that the objective response rate of Pembrolizumab and Nivolumab are 40% and 31.1% in MSI-H/dMMR (microsatellite instability-high/deficiency mismatch repair )colorectal cancer. What's more, most of the patients who had response for PD-1 antibody achieved a long duration of disease control. However, not all patients with MSI-H/dMMR was sensitive to PD-1 antibody despite it is a biomarker for PD-1 antibody treatment. There were about 50-60% of patients with MSI-H/dMMR were insensitive and we don't know why. What's more, it's reported that tumor mutation burden (TMB) may be another biomarker of response to PD-1 therapy. COX (cyclooxygenase)inhibitor has been proved to prevent adenomas in colorectal and it is safe for most of the patients. Preclinical models also showed that COX inhibitor could act with PD-1 antibody in mice and control disease progress. So, this study aims to evaluated efficacy and safety of combination of PD-1 antibody and COX inhibitor in patients with MSI-H/dMMR or high tumor mutation burden colorectal cancer.
This is a single arm, open-label, uni-center, phase I-II study to evaluate the safety and effectiveness of CAR-T/TCR-T cell immunotherapy in treating with different malignancies patients.
The overall objective of these studies are to confirm that ctDNA detected in plasma after intended curative treatment for CRC can be applied in clinical practice as a marker of subclinical residual disease and risk of recurrence.
The purpose of this study is to assess the efficacy of FOLFOX + panitumumab followed by FOLFIRI + bevacizumab (Sequence 1) versus FOLFOX + bevacizumab followed by FOLFIRI + panitumumab (Sequence 2) in untreated patients with wild-type RAS metastatic, primary left-sided, unresectable colorectal cancer
This study is designed to evaluate the short-term and long-term results after single incision laparoscopic surgery for colorectal cancer（SILSC） compared with conventional laparoscopic surgery for colorectal cancer（CLSC）.
