Recurrences of Hodgkin's disease (HD) ten or more years after initial therapy are rare and heterogeneous concerning pathological, biological and clinical features. Though usually regarded as relapses of initial disease at least part of these late recurrences may represent de-novo HD due to an increased constitutional risk. Following recent reports genetic risk for HD may be linked to the HLA-DPB1*0301 allele. Therefore, we investigated DPB1 and other HLA class I and II gene loci in three patients with very late recurrences of HD presenting at our institution within the last two years. All patients carry the HD susceptibility allele HLA-DPB1*0301. The expected probability of three patients with HD displaying the HLA-DPB1*0301 phenotype by chance is only p = 0.022. As serologic investigations also revealed Epstein-Barr virus (EBV) activity in all three cases our results support a role of genetic susceptibility possibly leading to impaired immune responses to EBV in very late recurring HD. Additionally, HLA-DPB1*0301 may be valuable for identifying patients with HD who might be candidates for a long term follow-up.
