Thus, we constructed a prognostic index for training cohort cancer samples using the following formula: risk score = (−0.606072 × expression of LIPE-AS1) + (−0.28451 × expression of AC124067.4) + (0.6666797 × expression of LINC01655) + (−0.988819 × expression of AP005131.3) + (−0.140664 × expression of AC008115.3) + (−0.767441 × expression of AC015802.3) + (−0.277495 × expression of USP30-AS1) + (−0.765508 × expression of SNHG26) + (0.138989 × expression of AL589765.4) (Table 2). Here, USP30 is linked to cancer.
