We aimed to assess independent predictors of early and late recurrence after RC and to analyze patterns of recurrence, in order to tailor a personalized follow-up protocol according to individual features. METHODS: We retrospectively analyzed data of 1,894 patients treated with RC. Considering a 3-year threshold value for the definition of late recurrence, patients with follow-up shorter than 3-year were excluded. The final cohort included 863 patients treated with RC for BCa at 4 tertiary referral centers between 2013 and 2017. Recurrence was coded as early (<3 years) and late (>3 years). Recurrence was coded as local (cystectomy bed or pelvic lymph node [LN] dissection template), urothelial (upper urinary tract and urethral carcinoma), and distant (including non-regional LNs) recurrence according to location. Multivariable Cox regression models were applied to predict risk of overall, early, and late recurrence; covariates consisted of clinical and pathological features. RESULTS: Overall, 11.7% and 12.5% of patients experienced early (median time: 22 months) and late (median time: 60 months) recurrence, respectively. Fig.1 depicts temporal distribution of recurrence according to location, showing a high risk of local and distant recurrence until the second year and urothelial recurrence until the fifth year after RC. Early recurrence occurred in non-regional LNs in 45% of cases, followed by lung (41%), local (21%), and urothelial recurrence (11%), while distant recurrence involved non-regional LNs, lung, urothelial, and local recurrence in 34%, 33%, 21%, and 19% of cases, respectively. At multivariable Cox analyses, pT3/4 (hazard ratio [HR]: 1.58; p=0.03), pN+ (HR: 2.06; 0<0.001), and positive surgical margins (HR: 2.03; p=0.04) were significantly associated with risk of overall recurrence, while pN+ and concomitant carcinoma in situ were independent predictors of early (HR: 3.00; p<0.001) and late (HR: 1.64; p=0.02) recurrence, respectively. CONCLUSIONS: Patients at increased risk for recurrence after RC should be referred to a stricter follow-up protocol, especially until the second year after RC and focused on distant recurrence.
