Advanced Hodgkin's lymphoma: results in 216 patients treated with ABVD in Brazil

The outcome of Hodgkin's lymphoma (HL) has markedly improved over the last few decades, placing HL among the human cancers with highest cure rates. However, data about treatment outcomes in developing countries are scarce. From 1996 to 2005, 370 consecutive patients with HL treated in three public institutions in Rio de Janeiro were identified. A total of 216 patients who presented with advanced stage (IIB-IV) HL were selected for the present analysis. Patients with advanced disease were treated with ABVD, complemented or not by radiation therapy. The median follow-up time of survivors was 6.3 years (1-11.8). Fifteen patients died during first-line treatment. The complete remission rate was 80%. The 5-year progression-free survival (PFS) and the 5-year overall survival (OS) probabilities were 69% and 83%, respectively. The 5-year PFS in low-risk and high-risk patients were 81% and 62% (p=0.003), respectively. The 5-year OS in low-risk and high-risk International Prognostic Score patients were 89% and 78% (p=0.02), respectively. The present study provides a representative estimate of current treatment results for advanced HL in public institutions in an urban area in Brazil. It is clear that full treatment can be given to most patients, although those with very low socio-economic status might require special attention and support. Since Brazil is a large country, with substantial interregional heterogeneity, a nationwide registry of HL patients is currently being implemented

AUGMENT : a phase III study of lenalidomide plus rituximab versus placebo plus rituximab in relapsed or refractory indolent lymphoma

PURPOSE Patients with indolent non-Hodgkin lymphoma typically respond well to first-line immunochemotherapy. At relapse, single-agent rituximab is commonly administered. Data suggest the immunomodulatory agent lenalidomide could increase the activity of rituximab. METHODS A phase III, multicenter, randomized trial of lenalidomide plus rituximab versus placebo plus rituximab was conducted in patients with relapsed and/or refractory follicular or marginal zone lymphoma. Patients received lenalidomide or placebo for 12 cycles plus rituximab once per week for 4 weeks in cycle 1 and day 1 of cycles 2 through 5. The primary end point was progression-free survival per independent radiology review. RESULTS A total of 358 patients were randomly assigned to lenalidomide plus rituximab (n = 178) or placebo plus rituximab (n = 180). Infections (63% v 49%), neutropenia (58% v 23%), and cutaneous reactions (32% v 12%) were more common with lenalidomide plus rituximab. Grade 3 or 4 neutropenia (50% v 13%) and leukopenia (7% v 2%) were higher with lenalidomide plus rituximab; no other grade 3 or 4 adverse event differed by 5% or more between groups. Progression-free survival was significantly improved for lenalidomide plus rituximab versus placebo plus rituximab, with a hazard ratio of 0.46 (95% CI, 0.34 to 0.62; P < .001) and median duration of 39.4 months (95% CI, 22.9 months to not reached) versus 14.1 months (95% CI, 11.4 to 16.7 months), respectively. CONCLUSION Lenalidomide improved efficacy of rituximab in patients with recurrent indolent lymphoma, with an acceptable safety profile

Bleomycin-Induced Lung Injury

Bleomycin is a chemotherapeutic agent commonly used to treat curable diseases such as germinative tumors and Hodgkin’s lymphoma. The major limitation of bleomycin therapy is pulmonary toxicity, which can be life threatening in up to 10% of patients receiving the drug. The mechanism of bleomycin-induced pneumonitis (BIP) involves oxidative damage, relative deficiency of the deactivating enzyme bleomycin hydrolase, genetic susceptibility, and the elaboration of inflammatory cytokines. Ultimately, BIP can progress to lung fibrosis. The diagnosis of BIP is established by the combination of systemic symptoms, radiological and histological findings, and respiratory function tests abnormalities, while other disorders should be excluded. Although the diagnosis and pathophysiology of this disease have been better characterized over the past few years, there is no effective therapy for the disease. In general, the clinical picture is extremely complex. A greater understanding of the BIP pathogenesis may lead to the development of new agents capable of preventing or even treating the injury already present. Physicians who prescribe bleomycin must be aware of the potential pulmonary toxicity, especially in the presence of risk factors. This review will focus on BIP, mainly regarding recent advances and perspectives in diagnosis and treatment

Human Germinal Center-Associated Lymphoma (HGAL) Protein Expression Is Associated with Improved Failure-Free Survival in Brazilian Patients with Classical Hodgkin Lymphoma

Abstract Abstract 4632 BACKGROUND The HGAL gene has prognostic value in diffuse large B-cell lymphoma and expression of its cognate protein is germinal center–specific. A previous study had suggested that HGAL protein expression might also be related to outcome in patients with Hodgkin lymphoma. PATIENTS AND METHODS The aim of the current study was to confirm the prognostic impact of HGAL protein expression in an independent, well-characterized cohort of 232 classic Hodgkin lymphoma patients treated uniformly with the ABVD regimen from 1997 to 2004 in Brazil. The median follow-up was 6.2 years. RESULTS Tissue microarray analysis showed HGAL staining in 188 specimens (81%). The overall survival was better in patients with young age, early-stage, absence of B symptoms, low-risk international prognostic score (IPS) and good performance status. Failure-free survival was superior in patients with early-stage disease, low-risk IPS and HGAL-positive patients. The estimated 5-year failure-free survival for HGAL-positive and HGAL-negative patients was 82% and 67%, respectively (P=0.03). When stage, B symptoms and performance status were included along with HGAL in a multivariate analysis, advanced stage and absence of HGAL staining were independent predictors of a worse failure-free survival. CONCLUSION This study confirms and validates recent findings of a correlation between HGAL expression and outcome in classical Hodgkin lymphoma.

Human germinal center-associated lymphoma protein expression is associated with improved failure-free survival in Brazilian patients with classical Hodgkin lymphoma

The human germinal center-associated lymphoma ( HGAL ) gene has prognostic value in diffuse large B-cell lymphoma, and expression of its cognate protein is germinal center-specific. A previous study had suggested that HGAL protein expression might also be related to the outcome in patients with Hodgkin lymphoma (HL). The aim of this study was to confirm the prognostic impact of HGAL protein expression in an independent, well-characterized cohort of 232 patients with classic HL treated uniformly with doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD). Tissue microarray analysis showed HGAL staining in 188 specimens (81%). Failure-free survival (FFS) was superior in patients with early-stage disease, low-risk IPS, and HGAL-positive patients. The estimated 5-year FFS for HGAL-positive and HGAL-negative patients was 82% and 67%, respectively ( p = 0.03). In the multivariate analysis, advanced stage and absence of HGAL staining were independent predictors of a worse FFS. This study confirms and validates recent findings of a correlation between HGAL expression and outcome in classical HL

Entretanto, os dados sobre tratamento em países em desenvolvimento são escassos. Entre 1996 e 2005, 370 pacientes consecutivos com LH tratados em três instituições públicas no Rio de Janeiro foram identificados. Destes, 216 em estádio avançado (IIB-IV) foram selecionados para esta análise. Os pacientes foram tratados com o protocolo ABVD (doxorrubicina, bleomicina, vinblastina e dacarbazina). A mediana do tempo de seguimento dos sobreviventes foi de 6,3 anos (1-11,8). Quinze pacientes morreram durante o tratamento de primeira linha. A probabilidade de sobrevida livre de progressão (SLP) em cinco anos e a probabilidade de sobrevida global (SG) em cinco anos foram de 69% e 83%, respectivamente. A SLP nos grupos de baixo risco e de alto risco, de acordo com o "International Prognostic Score", foi de 81% e 62% (p=0,003), respectivamente. A SG em cinco anos nos grupos de baixo risco e de alto risco foi de 89% e 78% (p=0,02), respectivamente. O presente estudo apresenta uma estimativa representativa dos resultados atuais do tratamento do LH avançado em instituições públicas no Brasil. Fica claro que o tratamento completo pode ser oferecido à grande maioria dos pacientes, embora aqueles com baixo status socioeconômico possam exigir atenção especial. Em vista das dimensões continentais do Brasil, com substancial heterogeneidade interregional, um registro nacional de pacientes com LH está sendo implementado

Detection of free circulating Epstein-Barr virus DNA in plasma of patients with Hodgkin’s disease

CONTEXT AND OBJECTIVE: Free circulating Epstein-Barr virus (EBV) DNA is often present in the plasma of Hodgkin’s disease patients. The aim here was to evaluate the prevalence of this finding, its correlation with the immunohistochemical expression of LMP-1 (latent membrane protein 1) and the influence of other clinical factors. DESIGN AND SETTING: Prospective study in two public tertiary institutions: Hematology Service, Universidade Federal do Rio de Janeiro, and Oncology Service, Instituto Nacional do Câncer, Rio de Janeiro. METHODS: A cohort of 30 patients with newly diagnosed Hodgkin’s disease was studied. The control group consisted of 13 healthy adult volunteers. EBV DNA was determined by conventional polymerase chain reaction (PCR). RESULTS: The median age was 28 years, and 16 patients were women. Advanced disease was present in 19 patients, and six were HIV-positive. EBV DNA was present in the plasma of 13 patients and one control (43% versus 8%, p = 0.03). EBV DNA prevalence was higher in HIV-positive patients (100% versus 29%, p = 0.0007) and those with advanced disease (63% versus 9%, p = 0.006). Among HIV-negative patients alone, EBV DNA prevalence remained higher in those with advanced disease. EBV DNA was found in 10/11 patients with LMP-1 expression in the lymph nodes, and in 3/19 without LMP-1 expression (kappa coefficient = 0.72). CONCLUSION: EBV DNA was present in 91% of patients with EBV-associated Hodgkin’s disease, and in all patients with HIV-associated Hodgkin’s disease. EBV DNA prevalence was higher in patients with advanced disease, irrespective of HIV status
