[Consensus of Chinese experts on clinical detection of molecular markers of colorectal cancer].

Colorectal cancer is one of the malignant tumors with the highest morbidity and mortality in China. With the research of precision medicine concept and tumor-related molecular markers, appropriate detection and application of colorectal cancer-related molecular markers has become an important part of current clinical practice. In order to effectively solve the current clinical problems and improve clinicians' understanding and application of molecular markers on colorectal cancer, the Chinese Society of Clinical Oncology(CSCO) Colorectal Cancer Expert Committee organized experts in related fields to write an expert consensus on molecular markers of colorectal cancer based on recent domestic and international clinical trial and clinical experience. The consensus mainly provides guidance on testing specimens, molecular markers and testing methods, and interpretation of testing results. It aims to provide clinicians with standardized clinical reference for diagnosis and treatment, and standard and effective treatment for patients with colorectal cancer.
