Abstract
Objective: We sought to identify tumor necrosis factor (TNF)-alpha-induced protein 8-like 2 (TIPE2/TNFAIP8L2) expression in bladder cancer and its relationship to clinicopathological findings and prognosis.Methods: Immunohistochemical (IHC) staining for TIPE2 was performed on 110 archived radical cystectomy specimens. Ten high-power fields were randomly selected from each specimen to observe and record the percentage of immunoreactive cells of TIPE2 in tumor cells (grade 0–4) and the corresponding immunostaining intensity (grade 0–3). The expression score of TIPE2 was obtained by multiplying the results of the above two scores, which ranged from 0 to 12 points. The cut-off point of the sum of the scores were defined as follows: 0–3 scores were defined as negative expression (-); >3 scores were classified as positive expression, < 7, low expression, ≥7, high expression.Results: In 110 cases, TIPE2 was stained in various degrees in bladder cancer tissues, and expressed in both nucleus and cytoplasm. 4.5% (5/110) showed negative expression, 40.9% (45/110) showed low expression, and 54.5% (60/110) showed high expression. TIPE2 expression was negatively correlated with lymph node metastasis (p = 0.004) and disease progression (p = 0.021). Survival curves were plotted to show that patients with high TIPE2 expression had a progression-free survival curve above those with negative/low TIPE2 expression (p = 0.027). In multivariate Cox proportional hazard regression analysis, TIPE2 was a protective factor for progression-free survival in bladder urothelial carcinoma (p = 0.031), pT stage (p = 0.016) was a risk factor for progression-free survival, and age was a risk factor for overall survival (p = 0.020).Conclusion: TIPE2 may be a new biomarker to predict the disease progression and prognosis of patients with urothelial carcinoma of the bladder.
