To enhance risk stratification, several clinical prediction models have been developed over time, particularly for advanced\u2010stage cHL. The International Prognostic Score (IPS), introduced in 1998, was the first widely adopted model, later refined in 2012 (updated IPS) and further simplified in 2015 (IPS\u20103). Despite their prognostic utility, these models have demonstrated declining predictive performance due to advancements in cHL treatment. In response, the HoLISTIC consortium recently introduced the Advanced\u2010Stage Hodgkin Lymphoma International Prognostic Index (A\u2010HIPI) in 2023. Unlike previous models, A\u2010HIPI incorporates continuous variables, aiming to provide a more precise risk assessment. However, its applicability to older patients remains uncertain, necessitating further validation studies. Additionally, none of the existing models incorporate dynamic treatment response markers such as interim positron emission tomography\/computed tomography (PET\/CT), which have shown strong prognostic value. This review comprehensively discusses the evolution, strengths and limitations of these prediction models, their clinical implications and the necessity for future refinements integrating dynamic biomarkers and treatment response indicators. The integration of machine learning and multi\u2010omics approaches could further enhance risk stratification, improve treatment personalization and optimize patient outcomes in cHL.<\/jats:p>","DOI":"10.1111\/bjh.70115","type":"journal-article","created":{"date-parts":[[2025,8,22]],"date-time":"2025-08-22T10:10:54Z","timestamp":1755857454000},"page":"1744-1754","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Refining the risk stratification in advanced\u2010stage classical Hodgkin lymphoma: A critical analysis of clinical prediction models"],"prefix":"10.1111","volume":"207","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1239-3246","authenticated-orcid":false,"given":"Oguzhan","family":"Koca","sequence":"first","affiliation":[{"name":"Department of Internal Medicine Cerrahpasa Faculty of Medicine, Istanbul University\u2010Cerrahpasa  Istanbul Turkey"},{"name":"Department of Immunology and Inflammation Faculty of Medicine, Imperial College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9568-0894","authenticated-orcid":false,"given":"Ahmet Emre","family":"Eskazan","sequence":"additional","affiliation":[{"name":"Division of Hematology, Department of Internal Medicine Cerrahpasa Faculty of Medicine, Istanbul University\u2010Cerrahpasa  Istanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,8,22]]},"reference":[{"key":"e_1_2_14_2_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199811193392104"},{"key":"e_1_2_14_3_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2011.41.0910"},{"key":"e_1_2_14_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/bjh.13634"},{"key":"e_1_2_14_5_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.22.02473"},{"key":"e_1_2_14_6_1","doi-asserted-by":"publisher","DOI":"10.3109\/10428194.2013.798868"},{"key":"e_1_2_14_7_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa0905680"},{"key":"e_1_2_14_8_1","doi-asserted-by":"publisher","DOI":"10.3324\/haematol.2010.031542"},{"key":"e_1_2_14_9_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood\u20102012\u201004\u2010421057"},{"key":"e_1_2_14_10_1","doi-asserted-by":"publisher","DOI":"10.3109\/10428194.2014.917636"},{"key":"e_1_2_14_11_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2012.43.4589"},{"key":"e_1_2_14_12_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood\u20102012\u201009\u2010454694"},{"key":"e_1_2_14_13_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.18.01652"},{"key":"e_1_2_14_14_1","unstructured":"Advanced Stage Hodgkin Lymphoma International prognostic index (A\u2010HIPI). n.d.
