- Abstract
Background: Prostate cancer is supposedly more aggressive among Afro-Caribbean men. There is a lack of data in this population for active surveillance. Published series are retrospective or have small samples and results are discordant. The objective was to determinate whether actual active surveillance modalities can be applied for Afro-Caribbean men by comparing their oncological outcomes with Caucasian men., Methods: A total of 449 consecutive patients who underwent active surveillance for favorable-risk prostate cancer in two French University-Medical-Centers between 2005 and 2018: 261 in Guadeloupe, French West Indies, and 188 in Bordeaux, metropolitan France. Median follow-up was 56 months, (95% CI [32-81]) and 52 months (95% CI [30-75]), respectively (P=0.07). Curative treatment was given in case of histological, biological, or imaging progression, or upon patient demand. Primary endpoints were treatment-free, overall and specific survival. Secondary outcomes were reasons of discontinuating active surveillance, histological poor prognosis factors after prostatectomy, CAPRA-S score, biochemical-recurrence-free after treatment and metastasis-free survival. Kaplan-Meier method was used., Results: Median treatment free survival was 58.4 months (CI 95% [48.6-83.1]) for ACM and not reached at 120 months for CM (P=0.002). Overall survival (P=0.53), and specific survival (P=0.21) were similar in the two groups. CM were likely to have poor prognosis factor on prostatecomy piece (57 vs 30%, P=0.01). No difference for repartition of the CAPRA-S score (P=0.86), biochemical-recurrence-free (P=0.92) and metastasis-free (P=0.44) survival., Conclusions: Oncological outcomes for active surveillance of Afro-Caribbean and Caucasian men were similar in terms of mortality, recurrence and metastasis in our bicentric study, showing usability of current criteria for Afro-Caribbean. The higher rate of disease progression in the Afro-Caribbean population requires close monitoring., Level of Evidence: 3., (Copyright © 2020 Elsevier Masson SAS. All rights reserved.)
