- Abstract
We retrospectively analyzed 70 patients with classical Hodgkin lymphoma (cHL) who were treated with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) with or without radiotherapy to assess the influence of the soluble interleukin-2 receptor (sIL-2R) level at diagnosis on the clinical outcome. Receiver operating characteristic analyses determined that the optimal cutoff value of the sIL-2R level for progression-free survival (PFS) was 2490 U/mL. Using this cutoff value, patients were classified into low (n = 46) and high (n = 24) sIL-2R groups. The patients in the high sIL-2R group exhibited a significantly inferior PFS (44.1% vs. 90.4% at 5 years, P < 0.001) and overall survival (OS) (67.6% vs. 94.7% at 5 years, P = 0.001) compared with those in the low sIL-2R group. Multivariate analysis showed that a high sIL-2R level was an independent prognostic factor for PFS after adjusting for stage, white blood cell, hemoglobin, and B symptoms, and also OS after adjusting for age and stage (hazard ratio (HR) 6.49, P < 0.001 and HR 5.98, P = 0.009, respectively). In patients with advanced-stage cHL, a high sIL-2R level predicted 5-year PFS even after adjustment for international prognostic score > 4 (HR 6.00, P = 0.007). These results demonstrate that the sIL-2R level can be a useful prognostic factor in patients with cHL treated with ABVD with or without radiotherapy.
