We seek to compare recurrence free survival (RFS) in patients receiving either BCG or Gem/Doce in the intermediate risk group composed mainly of patients with TaHG disease. METHODS: A retrospective analysis of consecutive patients treated with Gem/Doce or BCG for NIMBC between 2012-2023 was performed. Baseline characteristics, risk group stratification (AUA guidelines), pathological, and oncological outcomes were collected from electronic medical charts. RFS was assessed using the Kaplan-Meier method and log-rank test. R language version 4.3 was used for all statistical analyses. RESULTS: A total of 118 patients were included. The median age was 70 years (IQR 63-77), and 25 were females (21.2%). The median follow up period was 31 months (IQR 16-59). The intermediate risk group consisted of 66 (56%) patients with TaHG and 52 patients (44%) with TaLG. Seventy-seven patients were included in the BCG arm and 41 in the Gem/Doce arm. More patients had TaHG in the BCG group 64% vs. 42.5% (p=0.031). In the BCG group, 29.9% received maintenance therapy vs. 34% in the Gem/Doce group (p=0.68). For the entire cohort any grade recurrence occurred in 57 patients (48.3%) and high-grade recurrence in 23 patients (19.5%) without statistical difference between the groups. Kaplan-Meier curves demonstrated that patients in the Gem/Doce group had significantly worse RFS than the BCG group (log-rank, p=0.009, Figure 1A), with RFS of 67% vs 70% at 12 months, 52% vs 68% at 18 months, and 35% vs 62% at 24 months, respectively. No difference in RFS was found for high-grade recurrence (log-rank, p=0.36, Figure 1B). Progression to metastatic disease was 2.4% in the Gem/Doce group and 3.9% in the BCG group. CONCLUSIONS: In a cohort of patients with intermediate risk group consisting mainly of TaHG Gem/Doce has worse any grade RFS than BCG. No difference was found for high-grade RFS. Previously reported studies mainly compared patients with primary or recurrent TaLG disease. Our findings should be considered when tailoring the treatment for TaHG patients. Prospective trial with a larger cohort is necessary to validate our results.
