Abstract
Aim: To evaluate the prognostic value of autophagy proteinsin colorectal cancer (CRC). Methods: Six potential autophagy proteins were analyzed (Beclin-1, LC3A, LC3B, ULK1, ATG10and p62). Hazard ratios (HRs) and 95% CIsfor overall survival (OS) of CRC patients were calculated. Results: A total of20 studies were included. High expression of LC3B and p62 was associated with favorable OS (HR: 0.56, 95% CI: 0.40-0.80; HR: 0.76, 95% CI: 0.61-0.96), whereas high expression of Beclin-1 (HR: 1.47, 95% CI: 1.05-2.06) and ULK1 (HR: 1.92. 95% CI: 1.05-3.53) might predict worse OS in CRC patients. Conclusion: Beclin-1, LC3B and p62 might act as promising prognostic biomarkers for CRC. High LC3 and p62 expression can be reliable tools for metastasis prediction.
