Following the adjustment of the recurrence-related risk factors, the expression of PTTG2 and RAD21 was significantly associated with cancer recurrence (adjusted P value = 0.01, OR: 2.17 (95% CI: 1.24-3.86); adjusted P value = 0.03, OR: 1.88 (95% CI:1.08-3.28),respectively), while the low expression of MAD1L1 was associated with cancer recurrence (adjusted P value = 0.03, OR: 0.53 (%95 CI: 0.3-0.93), supplementary table 7). Here, PTTG2 is linked to cancer.
