Six classifications were identified, three of them were predictive models (EORTC, CUETO, EAU 2021) and three were based on expert opinion (EAU 2020, AUA, NCCN). A high risk of bias was present in the majority of the studies. Certain heterogenicity was found among the studies regarding adjuvant therapy, postoperative instillation or second resection. The definition of oncological outcomes was not standardized in the included studies. CUETO and EORTC scoring systems are the most validated. In general, validations showed a poor discrimination capability to predict recurrence, slightly better for progression. The EAU 2021 model overestimates the risk of progression in patients treated with BCG. Carcinoma in situ is underrepresented in all the studies analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>The existing classifications show poor discrimination capability for recurrence and possibly helpful discrimination capability for progression in NMIBC patients. These results highlight the unmet need to develop novel accurate risk models for patients with NMIBC, which could be improved with the combination of clinicopathological and molecular information.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3233\/blc-220055","type":"journal-article","created":{"date-parts":[[2022,10,21]],"date-time":"2022-10-21T11:55:09Z","timestamp":1666353309000},"page":"339-357","source":"Crossref","is-referenced-by-count":21,"title":["Predicting Recurrence and Progression in Patients with Non-Muscle-Invasive Bladder Cancer: Systematic Review on the Performance of Risk Stratification Models"],"prefix":"10.1177","volume":"8","author":[{"given":"F\u00e9lix","family":"Guerrero-Ramos","sequence":"first","affiliation":[{"name":"ROC Clinic, Madrid, Spain"},{"name":"Department of Urology, Hospital Universitario HM Sanchinarro, Madrid, Spain"},{"name":"Department of Urology, Hospital Universitario 12 de Octubre, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Daniel","family":"Subiela","sequence":"additional","affiliation":[{"name":"Department of Urology, Hospital Universitario Ram\u00f3n y Cajal, IRYCIS, Universidad de Alcal\u00e1, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00d3scar","family":"Rodr\u00edguez-Faba","sequence":"additional","affiliation":[{"name":"Department of Urology, Fundaci\u00f3 Puigvert, Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia","family":"Aumatell","sequence":"additional","affiliation":[{"name":"Department of Urology, Fundaci\u00f3 Puigvert, Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Celeste","family":"Manfredi","sequence":"additional","affiliation":[{"name":"Unit of Urology, Department of Woman, Child and General and Specialized Surgery, University of Campania \u201cLuigi Vanvitelli\u201d, Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giorgio","family":"Bozzini","sequence":"additional","affiliation":[{"name":"Department of Urology, ASST Lariana Ospedale Sant\u2019Anna, Como, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javier","family":"Romero-Otero","sequence":"additional","affiliation":[{"name":"ROC Clinic, Madrid, Spain"},{"name":"Department of Urology, Hospital Universitario HM Sanchinarro, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felipe","family":"Cou\u00f1ago","sequence":"additional","affiliation":[{"name":"Genesis Care Madrid, Madrid, Spain"},{"name":"Hospital San Francisco de As\u00eds, Madrid, Spain"},{"name":"Hospital La Milagrosa, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2022,10,20]]},"reference":[{"key":"ref001","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2021.08.010"},{"key":"ref002","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2009.04.038"},{"key":"ref003","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2013.07.021"},{"key":"ref004","doi-asserted-by":"publisher","DOI":"10.1111\/bju.14065"},{"key":"ref005","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2005.12.031"},{"key":"ref006","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2009.07.016"},{"key":"ref007","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2016.06.049"},{"key":"ref008","doi-asserted-by":"publisher","DOI":"10.6004\/jnccn.2020.0011"},{"key":"ref009","doi-asserted-by":"publisher","DOI":"10.1186\/2046-4053-4-1"},{"key":"ref010","doi-asserted-by":"publisher","DOI":"10.7326\/M18-1377"},{"key":"ref011","doi-asserted-by":"publisher","DOI":"10.7326\/M14-0698"},{"key":"ref012","doi-asserted-by":"publisher","DOI":"10.1590\/S1677-5538.IBJU.2015.0169"},{"key":"ref013","doi-asserted-by":"publisher","DOI":"10.1016\/j.clgc.2015.09.005"},{"key":"ref014","doi-asserted-by":"publisher","DOI":"10.4111\/kju.2014.55.10.643"},{"key":"ref015","first-page":"37","volume":"16","author":"Dalkilic A","year":"2019","journal-title":"Urol J"},{"key":"ref016","doi-asserted-by":"publisher","DOI":"10.1016\/j.urolonc.2021.10.008"},{"key":"ref017","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2011.05.033"},{"key":"ref018","doi-asserted-by":"publisher","DOI":"10.1016\/j.urolonc.2020.04.023"},{"key":"ref019","doi-asserted-by":"publisher","DOI":"10.1007\/s00345-010-0635-2"},{"key":"ref020","doi-asserted-by":"publisher","DOI":"10.1002\/cam4.3007"},{"key":"ref021","doi-asserted-by":"publisher","DOI":"10.5152\/tud.2016.77603"},{"key":"ref022","doi-asserted-by":"publisher","DOI":"10.1007\/s00345-018-2581-3"},{"key":"ref023","doi-asserted-by":"publisher","DOI":"10.1016\/j.acuro.2019.02.006"},{"key":"ref024","first-page":"39e21","volume":"38","author":"Leo MC","year":"2020","journal-title":"S. community-based health system.
