Limited evidence is available on the continuation of active surveillance in young prostate cancer patients in Germany.Using data that were reported, as required by law, to the population-based cancer registries of the German federal states of North Rhine-Westphalia, Baden-Württemberg, and Rhineland- - Palatinate, we studied the course of 732 patients under 60 years of age who were under active surveillance after receiving a diagnosis of low-risk localized prostate cancer (ISUP grade 1 or 2) in the years 2016-2021.The median duration of follow-up was 28 months. 64% [61%; 68%] of the patients were still under active surveillance at two years; this was true for 66% [62%; 70%] of those with ISUP grade 1 disease, 46% [37%; 58%] of those with ISUP grade 2 disease, and 72% [63%; 83%] of those for whom no Gleason grading was available. 62% of discontinuations occurred without any documented progression and without a documented patient-initiated decision.The two-year probability of young prostate cancer patients remaining under active surveillance was lower in Germany than in other countries. The cancer registries mostly received no information concerning the clinical rationale for the discontin uations. The potentially incomplete reporting of reasons for discontinuing active surveillance suggests that clinical reporting practices should be improved. 000304116 536__ $$0G:(DE-HGF)POF4-313$$a313 - Krebsrisikofaktoren und Prävention (POF4-313)$$cPOF4-313$$fPOF IV$$x0 000304116 588__ $$aDataset connected to CrossRef, PubMed, , Journals: inrepo02.dkfz.de 000304116 650_2 $$2MeSH$$aHumans 000304116 650_2 $$2MeSH$$aMale 000304116 650_2 $$2MeSH$$aProstatic Neoplasms: mortality 000304116 650_2 $$2MeSH$$aProstatic Neoplasms: therapy 000304116 650_2 $$2MeSH$$aProstatic Neoplasms: epidemiology 000304116 650_2 $$2MeSH$$aProstatic Neoplasms: diagnosis 000304116 650_2 $$2MeSH$$aProstatic Neoplasms: pathology 000304116 650_2 $$2MeSH$$aRegistries: statistics & numerical data 000304116 650_2 $$2MeSH$$aGermany: epidemiology 000304116 650_2 $$2MeSH$$aWatchful Waiting: statistics & numerical data 000304116 650_2 $$2MeSH$$aMiddle Aged 000304116 650_2 $$2MeSH$$aAdult 000304116 650_2 $$2MeSH$$aSurvival Rate 000304116 7001_ $$aJustenhoven, Christina$$b1 000304116 7001_ $$0P:(DE-He78)a8ce1da94e91296e574e4849cfabd230$$aHermann, Silke$$b2$$udkfz 000304116 7001_ $$0P:(DE-He78)aa0526e084994adfb97ce634da902be8$$aBrandhorst, Jana$$b3$$udkfz 000304116 7001_ $$aLakes, Jale$$b4 000304116 7001_ $$aWerner, Dominique$$b5 000304116 7001_ $$aKajüter, Hiltraud$$b6 000304116 7001_ $$aKarpinski, Madeleine$$b7 000304116 7001_ $$0P:(DE-He78)d023fdf423d87ee6c710e34dd7581fa0$$aArndt, Volker$$b8$$udkfz 000304116 7001_ $$aStang, Andreas$$b9 000304116 7001_ $$aAlbers, Peter$$b10 000304116 773__ $$0PERI:(DE-600)2406159-1$$a10.3238/arztebl.m2025.0081$$gVol. 122, no. 15$$n15$$p401-405$$tDeutsches Ärzteblatt international$$v122$$x1866-0452$$y2025 000304116 909CO $$ooai:inrepo02.dkfz.de:304116$$pVDB 000304116 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)a8ce1da94e91296e574e4849cfabd230$$aDeutsches Krebsforschungszentrum$$b2$$kDKFZ 000304116 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)aa0526e084994adfb97ce634da902be8$$aDeutsches Krebsforschungszentrum$$b3$$kDKFZ 000304116 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)d023fdf423d87ee6c710e34dd7581fa0$$aDeutsches Krebsforschungszentrum$$b8$$kDKFZ 000304116 9131_ $$0G:(DE-HGF)POF4-313$$1G:(DE-HGF)POF4-310$$2G:(DE-HGF)POF4-300$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vKrebsrisikofaktoren und Prävention$$x0 000304116 9141_ $$y2025 000304116 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bDTSCH ARZTEBL INT : 2022$$d2025-01-07 000304116 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2025-01-07 000304116 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2025-01-07 000304116 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2025-01-07 000304116 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2025-01-07 000304116 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2025-01-07 000304116 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2025-01-07 000304116 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bDTSCH ARZTEBL INT : 2022$$d2025-01-07 000304116 9201_ $$0I:(DE-He78)M110-20160331$$kM110$$lEpidemiologisches Krebsregister BW$$x0 000304116 980__ $$ajournal 000304116 980__ $$aVDB 000304116 980__ $$aI:(DE-He78)M110-20160331 000304116 980__ $$aUNRESTRICTED
