Objectives:
To investigate the association between the expression of nestin, a class VI intermediate filament protein, and pathologic features or survival in patients with urothelial carcinoma of the bladder (UCB).
Methods:
Nestin expression in tumor cells was immunohistochemically studied in 93 patients with UCB who underwent radical cystectomy with pelvic lymphadenectomy. The associations with clinicopathologic parameters were evaluated. Kaplan-Meier survival analysis and Cox proportional hazards models were used to estimate the effect of nestin expression on survival.
Results:
Nestin expression in cystectomy specimens was observed in 13 of 93 patients (14.0%). Nestin expression was associated with pathologic tumor stage (p = 0.006). Nestin-negative patients had better overall survival compared with nestin-positive patients (log-rank p = 0.0148). Univariable analysis indicated that nestin expression, lymphovascular invasion, and lymph node status were significantly associated with cancer-specific survival (hazard ratios, 2.78, 2.15, and 2.80, respectively). On multivariable analysis, nestin expression and lymph node status were independent prognostic factors in cancer-specific survival (hazard ratios, 2.45 and 2.65, respectively).
Conclusions:
The results suggest that nestin expression is a novel independent prognostic indicator for patients with UCB and a potentially useful marker to select patients who may be candidates for adjuvant chemotherapy.
