Background and AimsWe proved the feasibility of radical transurethral resection in selected patients with muscle-invasive bladder cancer with a minimum follow-up of >5 years. A follow-up schedule was developed based on progression and recurrence during this period.MethodsThe study included 93 patients with invasive bladder cancer treated by radical transurethral resection. Student t test was used for continuous variables to establish clinical progression predictive factors. VEGF-C protein expressions were tested by immunohistochemistry postsurgery.ResultsThe overall survival and disease-specific survival rates for all 93 patients were 59.1% and 65.2%, respectively. The clinical stage of the tumor influenced overall survival (p = 0.024) and disease-specific survival (p = 0.047). A significantly higher overall survival and disease-specific survival rate for patients with low levels of VEGF-C was 69.6% and 75.0%, respectively, than for those with high levels of VEGF-C (45.9 and 54.1%, respectively, p <0.05).The presence of bladder Tis reduced the survival rate (41.2 vs. 65.3%) and disease-specific survival (45.4 vs. 72.1%). Sensitivity, specificity and accuracy of VEGF-C in the evaluation of disease progression were 76.7, 77.8, 77.4%, respectively.ConclusionsPatients with T2 stage, low level of VEGF-C and absence of bladder Tis were associated with high overall survival and disease-specific survival rate. VEGF-C level can evaluate disease progression and assist in choosing the appropriate treatment.
