Results

Thirty-one out of 42 patients in the pirarubicin group remained free of intravesical recurrence (IVR) within 2 years, which was significantly higher than 19 out of 38 control patients (HR:0.47,95%CI:0.23-0.99,p=0.044). We did not have sufficient evidence to detect a difference in terms of OS (HR:0.83,95%CI:0.33-2.10,p=0.69) between the pirarubicin and the control groups. Multivariable analyses of factors associated with IVR revealed that only pirarubicin instillation was associated with IVR.

Baseline Characteristics

Median age was 75 (IQR 69-82) and 79 (IQR 69-84) in the pirarubicin and the control groups, respectively. Pelvic tumor was 26 (62%) and ureteral tumor was 16 (38%) in the pirarubicin group. In the control group, pelvic tumor was 23 (61%) and ureteral tumor was 15 (39%). Cases with ureteroscopic biopsy were 25 (60%) and 17 (45%) in the pirarubicin and the control groups, respectively. EAU high risk was 36 (86%) and high risk was 30 (79%), cases with high grade were 32 (84%) and 26 (72%), cases with muscle invasion were 15 (36%) and 19 (50%) and cases with concomitant carcinoma in situ were 4 (10%) and 4 (11%) in the pirarubicin and the control groups, respectively.

Participant flow

Between August 2012 and January 2019, 97 consecutive radical nephroureterectomy procedures performed were randomly assigned to either the pirarubicin group (n=49) or the control group (n=48). 7 patients in pirarubicin group (6 required adjuvant chemotherapy, 1 non-urothelial cancer) and 7 patients (4 required adjuvant chemotherapy, 3 non-urothelial cancer)in the control group were excluded for the efficacy analysis and remaining 80 patients (42 pirarubicin group and 38 control group) were analyzed.

Adverse events

Intraoperative spillage of the chemotherapy drug into the surgical field was not observed in the pirarubicin group patients. Only one case of Grade 1 postoperative urinary frequency related to instillation was observed among the pirarubicin group patients.
