Following the success of 2022’s meeting in Camogli, members of the PanProstate Cancer Group (PPCG) reconvened in Madrid in April 2023 to share their progress and enrich their collaborations. The April 2023 meeting was expertly organised and graciously hosted by Geoff Macintyre and his group at the Spanish National Cancer Research Center (CNIO). The team would especially like to thank Bárbara Hernando, a postdoctoral researcher in the Macintyre group, for her tireless work organsing the conference and liaising with IT support to ensure that the hybrid meeting went without a hitch.
