Now, 10 years later, the current status of the expanded cancer registration is presented, including current figures on cancer in Germany. Methods: Reporting of cancer is mandatory for physicians, and about 5 to 10 reports from different healthcare providers are expected for each case. A uniform national dataset of about 130 items is used, and reports are usually sent electronically to the registry. We used the most recent data available from cancer registries up to the year of diagnosis in 2019. We calculated incidence rates and 5-year relative survival (5YRS) for common cancers. Data on clinical outcomes and benchmarking based on quality indicators (QIs) from guidelines were provided by the Cancer Registry Schleswig-Holstein (CR SH). Results: All federal state cancer registries met most of the previously defined national eligibility criteria. Approximately 505,000 cancer cases were registered in 2019, with breast, prostate, colorectal and lung cancer being the most common cancers. The age-standardised cancer incidence has slightly decreased during the last decade. and spatial heterogeneity can be observed within Germany. 5YRS for all cancers was 67% and 63% for women and men, respectively. Therapy data for rectal cancer in 2019\u20132021 from the CR SH are shown as an example: 69% of the registered patients underwent surgery, mostly with curative intent (84%) and tumour-free resection (91%). Radiotherapy was given to 33% of the patients, and chemotherapy was given to 40%. Three selected QIs showed differences between involved healthcare providers. Discussion: The implementation of population-based clinical cancer registration can be considered a success. Comprehensive recording of diagnosis, treatment and disease progression and the use of registry data for quality assurance, benchmarking and feedback have been implemented.<\/jats:p>","DOI":"10.3390\/cancers15153934","type":"journal-article","created":{"date-parts":[[2023,8,2]],"date-time":"2023-08-02T11:17:17Z","timestamp":1690975037000},"page":"3934","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":64,"title":["Population-Based Clinical Cancer Registration in Germany"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0490-1554","authenticated-orcid":false,"given":"Alexander","family":"Katalinic","sequence":"first","affiliation":[{"name":"Cancer Registry Schleswig-Holstein, 23562 L\u00fcbeck, Germany"},{"name":"Institute for Social Medicine and Epidemiology, University of L\u00fcbeck, 23562 L\u00fcbeck, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco","family":"Halber","sequence":"additional","affiliation":[{"name":"Cancer Registry Baden-Wurttemberg, 70191 Stuttgart, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Meyer","sequence":"additional","affiliation":[{"name":"Bavarian Cancer Registry, 90441 Nurnberg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maren","family":"Pfl\u00fcger","sequence":"additional","affiliation":[{"name":"Cancer Registry Brandenburg-Berlin, 03048 Cottbus, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Eberle","sequence":"additional","affiliation":[{"name":"Cancer Registry Bremen, 28359 Bremen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7115-5160","authenticated-orcid":false,"given":"Alice","family":"Nennecke","sequence":"additional","affiliation":[{"name":"Hamburg Cancer Registry, 20097 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soo-Zin","family":"Kim-Wanner","sequence":"additional","affiliation":[{"name":"Hessian Cancer Registry, 60439 Frankfurt, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tobias","family":"Hartz","sequence":"additional","affiliation":[{"name":"Cancer Registry Lower Saxony, 30659 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kerstin","family":"Weitmann","sequence":"additional","affiliation":[{"name":"Cancer Registry Mecklenburg-Western Pomerania, 17475 Greifswald, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Stang","sequence":"additional","affiliation":[{"name":"Cancer Registry North Rhine-Westphalia, 44801 Bochum, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christina","family":"Justenhoven","sequence":"additional","affiliation":[{"name":"Cancer Registry Rhineland-Palatinate, 55116 Mainz, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8759-4371","authenticated-orcid":false,"given":"Bernd","family":"Holleczek","sequence":"additional","affiliation":[{"name":"Saarland Cancer Registry, 66119 Saarbrucken, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Piontek","sequence":"additional","affiliation":[{"name":"Joint Office of the Clinical Cancer Registries in Saxony, 01099 Dresden, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ian","family":"Wittenberg","sequence":"additional","affiliation":[{"name":"Cancer Registry Saxony-Anhalt, 06112 Halle (Saale), Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annika","family":"He\u00dfmer","sequence":"additional","affiliation":[{"name":"Cancer Registry Thuringia, 07743 Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Klaus","family":"Kraywinkel","sequence":"additional","affiliation":[{"name":"Centre for Cancer Registry Data at the Robert Koch-Institute, 12101 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia","family":"Spix","sequence":"additional","affiliation":[{"name":"Division of Childhood Cancer Epidemiology, German Childhood Cancer Registry, 55101 Mainz, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2858-2941","authenticated-orcid":false,"given":"Ron","family":"Pritzkuleit","sequence":"additional","affiliation":[{"name":"Cancer Registry Schleswig-Holstein, 23562 L\u00fcbeck, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,2]]},"reference":[{"key":"ref_1","unstructured":"Leyden, E., Kirchner, M., Wutzdorf, E., Hansemann, D., and Meyer, G.
