Abstract:
Objective:To evaluate the recurrence and progression of patients with pT1 high grade urothelial carcinoma of bladder (UCB) and glandular differentiation.Methods:We retrospectively analyzed the clinical and pathological information of 208 patients diagnosed as pT1 high grade urothelial carcinoma in the Fifth Central Hospital of Tianjin from January 2006 to February 2019.Among them, 78 cases were diagnosed as glandular differentiation (UCGD), the other 130 patients without histologic variants were served as control. The UCGD group included 62 male and 16 female, whose median age was 67 years old (range 38-81 years old). The control group contained 105 male and 25 female, whose median age was 66 years old (range 40-82 years old). Kaplan-Meier and Cox proportional hazard regression analyses were used to evaluate the predictors of oncologic outcomes.Results:The disease recurrence rate and progression rate in UCGD group were 65.4% (51/78) and 28.2% (22/78), higher than 38.5%(50/130) and 14.6%(19/130) of control group ( P<0.05). The median recurrence time in UCGD group was 41 months while 55 months in the control group. The median progression time in UCGD group was 39 months while 54 months in the control group. According to the univariate analysis, largest tumor size ( P=0.030), UCGD ( P=0.003) and lymphovascular invasion (LVI) ( P=0.032) were associated with disease recurrence. UCGD ( P=0.036) and LVI ( P=0.011) were associated with progression. Additionally, Cox multivariate analysis revealed that UCGD ( P=0.001), LVI ( P=0.038) were the independent factors of disease recurrence. UCGD ( P=0.007) and LVI ( P=0.037) were also found to be the independent factors of disease progression. Conclusions:Patients with T1 stage UCB and UCGD are at higher risk of disease recurrence and progression. Therefore, these patients should be followed up closely after being diagnosed and undergo individual treatment according to the situation.
