The International Prognostic Scoring System (IPSS) [1], the gold standard for risk assessment in myelodysplastic syndromes (MDS), has been recently revised (IPSS-R).The authors proposed a new prognostic model including novel components: five cytogenetic prognostic subgroups with specific classification of a number of less common cytogenetic subsets [2, 3]; the <5 % bone marrow blasts category was split between 0-2 % and >2-<5 %; depth of cytopenias at clinically relevant cut-points for haemoglobin level, platelet count, and absolute neutrophil count [2].As the score [2] was established in MDS patients including all French-American-British classification subtypes [4], the aim of this study was to

Myelodysplastic syndromes (MDS) constitute a heterogeneous group of clonal hematological diseases characterized by refractory cytopenia(s). MDS patients show increased levels of tumor necrosis factor alpha (TNFα) which is a multifunctional proinflammatory cytokine. The aim of this work is to examine the presence of -308A/G TNFα variants and to analyze whether it is associated with clinical parameters in a cohort of 101 Argentinean de novo MDS patients. The A/A+A/G genotype at TNFα -308 was overrepresented 2-fold in our population (p=0.0499, odds ratio-OR: 2.107) and these differences were more evident in RA-FAB subtype (p=0.0424, OR: 2.502). The presence of the high expressing -308A allele was associated with lower hemoglobin level (8.3 vs 9.9g/dL; p=0.0206), reduced platelet counts (89,000 vs 130,000/μL; p=0.0381) and younger age (59 vs 68years; p=0.0122) at diagnosis. Also, these patients showed 3.8-fold higher risk of transfusion requirement (76% vs 46%, p=0.0105) during the follow up. In conclusion, the presence of an inherited -308A TNFα, which increases its transcription level, was associated with the MDS phenotype in our cohort of Argentine MDS patients. Also, an overexpression of TNFα may promote an underlying proinflammatory state that cooperates with intrinsic defects within MDS progenitors to increase the severity of certain phenotypic features of the disease.

BACKGROUND Doxorubicin/bleomycin/vinblastine/dacarbazine (ABVD) plus involved-field radiation therapy (IFRT) is the gold-standard treatment for early and advanced stages of Hodgkin lymphoma (HL). We evaluated the outcomes of patients according to prognosis at diagnosis and over time to determine who achieved complete remission (CR). PATIENTS AND METHODS Treatment-naive patients under the age of 75 years at all stages of HL were eligible. The favorable group (FG) contained patients with stage IA-IIIA disease without bulky areas who achieved CR after the third cycle of ABVD. They received only IFRT at 25 Gy. Patients in the unfavorable group (UG) exhibited stages IIIB and IV HL. The UG also included all patients with bulky disease and the subset of the FG without CR after 3 cycles of ABVD, ie, slow responders (FGSR). The UG received 6 cycles of ABVD plus IFRT at 30 Gy to bulky areas at diagnosis or to those areas remaining positive after the third cycle of ABVD. RESULTS In total, 584 patients were evaluable: 285 of them belonged to the FG, and 299 to the UG. Rates of CR were 98% and 85% for the FG and the UG, respectively (P < .001). Sixty patients in the FG received 6 cycles of ABVD because they had not achieved CR after 3 cycles (ie, the FGSR subgroup). The 5-year event-free survival rate was 89% for the FG, 66% for the FGSR, and 72% for the UG (P < .001). The overall survival at 5 years was significantly better for the FG (98%) than for the FGSR (87%) and the UG (88%; P < .001). CONCLUSION Patients from the FG demonstrated excellent outcomes compared with those from the FGSR and UG, despite receiving less chemotherapy and fewer doses of IFRT.

Background: The prognostic score for Hodgkin's lymphoma was defined as the number of adverse prognostic factors presented at diagnosis. Seven factors had similar independent prognostic effects. This model was validated retrospectively in advanced disease using different therapeutic approaches (D Hasenclever et al N Eng J Med 339:1506–14, 1998).

Background: The present goal for the treatment of HL is to develop a combined modality therapy with high response rate, disease-free survival (DFS) and overall survival (OSV) with minimal toxicity.
