A number of ATG genes can serve as prognostic factors, such as SNP variant rs17094017 A > T in ATG2B (better prognosis for patients receiving oxaliplatin-based chemotherapy, increased disease control rate after treatment) [43], Beclin-1 and Rab-7 for OS and progression-free survival (PFS) in CRC [44] and BAX and poly [ADP-ribose] polymerase 1 (PARP1) for CRC recurrence (71.1%) [45]. Here, PARP1 is linked to colorectal carcinoma.
