ABSTRACT: Background
Carbohydrate antigen 19-9 (CA 19-9) is one of the most frequently used tumor markers for gastrointestinal cancer, particularly for diagnostic purposes. However, its value in predicting prognosis remains controversial. In this study, we sought to clarify this by conducting a meta-analysis of relevant studies.Methods
We systematically searched several databases, including PubMed, EMBASE and Web of Science for articles pertaining to the relationship between pretreatment serum CA 19-9 levels and prognosis in patients with colorectal cancer (CRC).
