Unfavorable early-stage Hodgkin lymphoma: assessment of patient characteristics in a real-world setting.

Unfavorable prognostic factors among classical Hodgkin lymphoma (cHL) patients in the real-world setting have yet to be fully characterized. In this retrospective study using the ConcertAI Oncology Dataset, patient characteristics, unfavorable prognostic factors and treatment patterns were evaluated among patients diagnosed with cHL. Among 324 adult cHL patients diagnosed 2016-2021, 16.1% were classified as early favorable, 32.7% early unfavorable and 51.2% advanced disease. Early unfavorable patients were younger and had a larger nodal mass. The prognostic factor B symptoms was most frequently documented in early unfavorable patients (59.4%), followed by bulky disease (46.2%), >3 involved lymph node regions (31.1%), and erythrocyte sedimentation rate ≥50 (25.5%). In this analysis of real-world data, we found that nearly a third of newly diagnosed cHL patients had early unfavorable disease. Our analysis also showed differences in the proportion of patients for each unfavorable factor among patients with early-stage unfavorable cHL.
