ABSTRACT
Objective:
To examine whether multiple-course prophylactic intravesical instillation chemotherapy is superior to single-course chemotherapy in preventing bladder tumor recurrence after radical nephroureterectomy(RNU)for primary upper tract urothelial carcinoma(UTUC).Methods:
A comprehensive literature search was performed using the PubMed, Wanfang Data and China National Knowledge Infrastructure and all publications before March 2021 about clinical trials comparing the effects of single-course and multiple-course prophylactic intravesical instillation chemotherapy after RNU for UTUC were retrieved.Analysis was performed using Stata/SE 12.0.Results:
Seven trials included a total of 998 patients, with 473 participants receiving multiple-course and 525 receiving single-course intravesical instillation chemotherapy.Bladder cancer recurrence occurred in 69 out of 473 patients(14.6%)with multiple-course chemotherapy and in 123 out of 525 patients(23.4%)with single-course chemotherapy.The absolute risk reduction was 8.8% and the relative risk reduction was 37.6%.Compared with a single-course instillation, the pooled OR of bladder cancer recurrence was 0.55(95% CI 0.40-0.76, P<0.001)for multiple-course instillations.No serious adverse events were reported.Conclusions:
Compared with single-course instillation chemotherapy, multiple-course prophylactic intravesical instillation chemotherapy significantly decreases the risk of bladder cancer recurrence in primary UTUC patients treated with RNU, indicating multiple intravesical instillation chemotherapy is superior to single instillation chemotherapy.
