Filter by:The aim of this international multicenter study is to compare the adenoma detection rate and adenoma miss rate of conventional and Endocuff Vision-assisted colonoscopy.
This is a phase II, open label, multicenter study. Patients with advanced colon rectal cancer (CRC) harboring an amplified HER2 that have been previously treated and progressed with an aNti-HER2 treatment, will be treated with the anti HER2 antibody conjugate trastuzumab emtansine (TDM1). Patients will receive study medication until disease progression, unacceptable toxicity, withdrawal of consent or death. Main objective of the study is the evaluation of objective response rate according to RECIST 1.1 criteria. Disease control rate, defined as the sum of complete, partial and stable disease patients over total patient, followed by response duration, time to progression and safety are secondary endpoints.
This study is to evaluate circulating tumor DNA (ctDNA) as a predictive and surveillant method for tumor recurrence in stage II and III colorectal cancer (CRC).
The primary objective is to determine the sensitivity and specificity of two Colorectal Cancer (CRC) screening methods, including stool DNA test and blood mRNA test, for colorectal cancer in Chinese population, with colonoscopy as reference method. Lesions will be confirmed as malignant or precancerous by colonoscopy and histopathologic examination. The secondary objective is to compare the performance of these two CRC screening methods to a commercially available FIT assay, both with respect to cancer and advanced adenoma. Lesions will be confirmed as malignant or precancerous by colonoscopy and histopathologic examination.
This is an Exploratory Clinical Trial Study on Apatinib in the Treatment of Metastatic Colorectal Cancer Who Have Progressed after Standard Second Line Therapy.
To evaluate the emergence of RAS mutation in patients with metastatic colorectal cancer, circulating free DNA will be analyzed using mass spectrometric genotyping in subjects during cetuximab treatment. The hypothesis of this study is that acquired RAS mutation is responsible for the resistance to cetuximab treatment in wild-type colorectal cancer. The usefulness of liquid biopsy to monitor dynamic genetic alterations in colorectal cancer during treatment will also be investigated in this study.
The purpose of this study is to confirm the safety and efficacy of Apatinib plus S-1 as the Therapy of Advanced Colorectal Cancer.
The study is designed as phase III, randomized, two armed, parallel, double blind (patient and assessor blinded), active controlled, and equivalency clinical trial with primary endpoint of Progression-Free Survival of Cetuximab® (produced by CinnaGen) compared with Erbitux® (Cetuximab, the reference drug) in patients with RAS wild-type Metastatic Colorectal Cancer with the allocation ratio of 2:1.Patients who met the following criteria could be recruited to receive the mentioned intervention randomly. Inclusion criteria: Male or female older than 18 years old, histologically confirmed adenocarcinoma of the colon or rectum which is metastatic, having one or more bi-dimensionally measurable lesions as defined by RECIST criteria, tumor that could not be resected for curative purposes,ECOG performance status score of 2 or less,life expectancy of longer than 3 months (clinical assessment),evidence of tumor EGFR expression (expanded wild-type RAS),adequate organ and marrow function as defined: ANC ≥ 1,500/mm3 Plt ≥ 100,000/mm3 Hb ≥ 9 g/dL (may have had blood transfusions) AST/ALT ≤ 2.5 IULN or ≤ 5 IULN with known liver metastases Total bilirubin ≤ 1.5 IULN Serum Creatinine ≤ 1.5 IULN INR ≤ 1.5 and PTT ≤ 1.5 IULN
Colonic microbiome has been found to contribute to the development of colorectal cancer. We speculate that gut microbiota related to colorectal cancer relapse after curative treatment. This study aim to discover if any difference of gut microbiota exist in patients who suffer from cancer relapse compared with patients who do not. Finally develop patient-centred programmes of surveillance protocols base on microbiota analysis.
The protein tyrosine kinase-7 (PTK7) is overexpressed in various types of human cancers. As a specific imaging agent of PTK7, 68Ga-Sgc8 was investigated in this study to assess its safety, biodistribution and dosimetric properties in healthy volunteers, and to preliminarily evaluate its application in colorectal patients.
