Various autophagy proteins have favorable prognostic value in oncology, for example, LC3B in non-small cell lung cancer (NSCLC) [111] and breast cancer (BC) [112]; LC3A in colorectal cancer (CRC) [113] and BC [114]; p62, and ULK1 in BC [115] and gastric cancer (GC) [116]; Atg3 in GC [116]; Atg10 in GC [116]; Atg7 and FIP200 in BC; and Beclin-1 and VPS34 in GC, BC, NSCLC, CRC, and lymphoma [117]. Here, ATG3 is linked to breast cancer.
