Study Overview
Brief Summary
The aim of this study is to investigate the effects of environmental factors, such as air pollution, on the occurrence, development and prognosis of colorectal cancer; to identify metabolic markers specific to colorectal cancer patients, which will provide a basis for early diagnosis, early intervention and individualized treatment; and to comprehensively understand the mechanism of the occurrence and development of colorectal cancer by integrating the data of environmental factors and the macro-genome, and to develop new predictive and therapeutic strategies.
