摘要
Radical surgery (RS) with adjuvant chemotherapy (AC) or radiotherapy has been conventionally used for patients with advanced urothelial carcinoma (AUC). Recent research has indicated that systemic neoadjuvant chemotherapy (NC) with RS yields better outcomes than RS alone for patients with locally advanced bladder cancer. However, there are no reports indicating whether NC or AC would be beneficial for patients with AUC. The present study compared the survival rate for AUC patients receiving NC or AC. A retrospective analysis was conducted using data for 64 patients with AUC who underwent RS and systemic chemotherapy at our institution between March 2002 and March 2011. Of the 64 patients, 30 received NC before RS and 34 received RS followed by systemic AC. Pathologic stages (p = 0.002), grades (p = 0.018) and lymphovascular invasion (p = 0.047) were significantly lower in the patients who received NC first than in those who received RC first. Furthermore, analysis of the surgical specimens revealed that 26.7% of patients who received NC before RS had complete remission. There were no significant differences in demographic data, surgical complications, and chemotoxicity between the two patient groups. The progression-free survival (PFS) and overall survival (OS) of patients who received initial NC were significantly better than those of patients who received initial RC (p = 0.002 and 0.018, respectively). Our results indicate that NC administration before RS significantly improved the PFS and OS of AUC patients, without increasing surgical complications and chemotoxicity. Further prospectively controlled trials need to be conducted to confirm the effectiveness of NC for AUC patients.
