ABSTRACT The International Prognostic Score (IPS) identifies seven independent factors predicting progression-free and overall survival in advanced stage Hodgkin's disease (HD). The IPS is also applicable in limited disease. However, the IPS does not identify patients with a very poor prognosis. The aim of this study was to define biological markers which may add to the IPS in predicting outcome.
One hundred forty-five patients (> 15 years) with HD of all stages and histopathology subgroups were included. In addition to factors included in the IPS, serum levels of CRP, sCD4, sCD8, sCD25, sCD30, sCD54, interleukin (IL)-10, beta2-microglobulin and thymidine kinase were analysed.
The strongest predictors of a poor cause-specific survival (CSS) in univariate analyses were: increased serum levels of IL-10, sCD30 and CRP, anaemia, low levels of albumin (P < 0.001); stage IV (P = 0.003), age > or = 45 years (P = 0.006), increased serum levels of sCD25 (P = 0.010), low lymphocyte counts (P = 0.020). Serum IL-10 added prognostic information to that achieved by the IPS: patients with a high score and increased serum IL-10 had a very poor outcome with a five-year CSS of 38%. Patients with increased serum levels of sCD30 and a high score also had a poor outcome with a five-year CSS of 54%.
Serum levels of IL-10 and sCD30 may add to IPS in prediction of outcome in HD, and should be validated in large, prospective studies.

    ABSTRACT: Cytokines are important immune mediators of classical Hodgkin lymphoma (CHL) pathogenesis, and circulating levels at diagnosis may help predict prognosis. Germline single nucleotide polymorphisms (SNPs) in immune genes have been correlated with cytokine production and function. We investigated whether selected germline SNPs in IL10 (rs1800890, rs1800896, rs1800871, rs1800872), TNFA (rs1800629), IL6 (rs1800795), ILRN (rs419598), INFG (rs2430561) and CCL17 (rs223828) were associated with circulating levels of related cytokines at diagnosis and progression-free survival (PFS) in CHL. Patients were from France (GELA, N=464; median age=32years) and the United States (Iowa/Mayo Specialized Program Of Research Excellence [SPORE], N=239; median age=38years); 22% of 346 CHL cases with EBV tumor status were positive. There was no association with any of the SNPs with cytokine levels. Overall, there was no association of any of the SNPs with PFS. In exploratory analyses by EBV status, TNFA rs1800629 (HRAA/AG=2.41; 95%CI, 1.17-4.94) was associated with PFS in EBV-negative GELA patients, with similar trends in the SPORE patients (HRAA/AG=1.63; 95%CI, 0.61-4.40). In a meta-analysis of the two studies, TNFA (HRAA/AG=2.11; 95%CI, 1.18-3.77; P=0.01) was statistically significant, and further adjustment for the international prognostic system did not alter this result. This study showed that germline variation in TNFA was associated with CHL prognosis for EBV-negative patients, which will require confirmation. These results support broader studies on the differential impact of genetic variation in immune genes on EBV-positive vs. EBV-negative CHL pathogenesis.

    ABSTRACT: The levels of serum beta-2 microglobulin (β2MG) are determined mainly from lymphoid tissue. To examine its prognostic value in Hodgkin lymphoma (HL), we conducted a retrospective analysis. We analyzed 67 patients with HL diagnosed and treated at seven institutes of the Yokohama City University Hematology Group between 1998 and 2011. The patients included 40 males and 27 females with a median age of 41 years (range 16-81 years). The HL subtypes were nodular sclerosis classical HL in 37 patients, mixed cellular classical HL in 23, lymphocyte-rich classical HL in 6, and nodular lymphocyte-predominant HL in 1. The 4-year overall survival (OS) rate of all 67 patients was 89 %. Patients with β2MG levels ≥2.5 mg/L (n = 18) showed inferior progression-free survival (PFS; 4-year PFS rate, 42 %) and inferior OS (4-year OS rate, 60 %) compared to patients who had β2MG levels <2.5 mg/L (n = 49; 4-year PFS rate, 87 %; 4-year OS rate, 98 %; P < 0.001). In multivariate analysis, only a serum β2MG level ≥2.5 mg/L was a significant adverse prognostic factor in regard to PFS (P = 0.04; relative risk 3.57). However, it was not significant prognostic factor for OS (P = 0.16) in the multivariate analysis. The serum β2MG level at diagnosis is a useful prognostic marker in patients with HL.

    ABSTRACT: Hodgkin lymphoma (HL) is among the neoplastic diseases that has the best long-term outcome after cytotoxic treatment. Cure rates approach 80-90%; however, 15-20% of patients will be resistant to therapy (primary refractory) or relapse after treatment. Prognostic factors should help to stratify treatment according to the risk profile and identify patients at risk for failure. Significance of prognostic factors partly depends on the efficacy of the treatments administered, since new effective therapies can variably counterbalance the adverse effects of some unfavorable clinical determinants. As a consequence, some prognostic factors thought to be important in the past may become meaningless when modern successful therapies are used. Therefore, the value of prognostic factors has to be updated periodically, and then adapted to new emerging biomarkers. Besides the prognostic role of PET imaging, tissue and circulating biomarkers, as the number of tumor-infiltrating macrophages, cytokine and chemokine levels and profiling of circulating nucleic acids (DNA and microRNAs) have shown promise.
