We aimed to evaluate the prognostic impact of the number, ratio, and\/or grouping of Hodgkin\/Reed\u2013Sternberg (HRS) cells in patients with CHL. Materials and Methods: 135 consecutive adult patients with CHL were included. The number, ratio, and grouping of HRS cells were evaluated on hematoxylin\u2013eosin (HE) and CD30-stained slides. The ratio and group formation were scored. Results: Female:male ratio was 0.82. The median age was 36 \u00b1 15.8 (range: 18\u201382 years). The number of HRS cells was significantly higher in nodular sclerosis CHL than in mixed-cellularity CHL and lymphocyte-rich CHL. Also, the number of HRS cells was significantly higher in syncytial variant nodular sclerosis CHL (SV-NSCHL). HRS cell ratio was in the range of 6\u201325% in more than 50% of the cases on both HE- and CD30-stained slides. The number of cases with a group score of 0 (no HRS groups) was significantly higher among men compared to women. HRS cells mostly did not form groups in EBER-positive patients. Confluent\/large groups were more common in SV-NSCHL. Response to first-line therapy, gender, and EBER positivity were found to be independent prognostic factors. The number, ratio, and grouping of HRS cells were not associated with OS, stage, recurrence, and\/or response to first-line treatment. Conclusions: The number, ratio, and\/or grouping of HRS cells do not have any significant prognostic impact on CHL patients, however future studies are required to explore their pathogenetic implications.<\/jats:p>","DOI":"10.3390\/medicina62081569","type":"journal-article","created":{"date-parts":[[2026,8,17]],"date-time":"2026-08-17T08:05:41Z","timestamp":1786953941000},"page":"1569","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Quantity Does Not Matter: Number, Ratio, or Grouping of Hodgkin\/Reed\u2013Sternberg Cells Does Not Affect Prognosis in Patients with Classic Hodgkin Lymphoma"],"prefix":"10.3390","volume":"62","author":[{"given":"Burcin","family":"Pehlivanoglu","sequence":"first","affiliation":[{"name":"Department of Pathology, Faculty of Medicine, Dokuz Eylul University, Balcova, Izmir 35330, Turkey"},{"name":"Department of Molecular Pathology, Insitute of Health Sciences, Dokuz Eylul University, Balcova, Izmir 35330, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-9641-5293","authenticated-orcid":false,"given":"Nazimcan","family":"Tezel","sequence":"additional","affiliation":[{"name":"Department of Pathology, Faculty of Medicine, Dokuz Eylul University, Balcova, Izmir 35330, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Osman Can","family":"Ozturk","sequence":"additional","affiliation":[{"name":"Department of Hematology, Faculty of Medicine, Dokuz Eylul University, Balcova, Izmir 35330, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Serra Begum","family":"Emecen","sequence":"additional","affiliation":[{"name":"Department of Pathology, Faculty of Medicine, Dokuz Eylul University, Balcova, Izmir 35330, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mehmet Ali","family":"Ozcan","sequence":"additional","affiliation":[{"name":"Department of Hematology, Faculty of Medicine, Dokuz Eylul University, Balcova, Izmir 35330, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sermin","family":"Ozkal","sequence":"additional","affiliation":[{"name":"Department of Pathology, Faculty of Medicine, Dokuz Eylul University, Balcova, Izmir 35330, Turkey"},{"name":"Department of Molecular Pathology, Insitute of Health Sciences, Dokuz Eylul University, Balcova, Izmir 35330, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,17]]},"reference":[{"key":"ref_1","unstructured":"Gujral, S., Siebert, R., and de Jong, D.
