RESUMO

The treatment of older patients with Hodgkin lymphoma (HL) remains a challenge. We sought to identify the treatment patterns and outcomes in older HL patients included in the Brazilian HL registry (NCT02589548). A total of 136 patients with HIV-negative classic HL, aged ≥ 60 years, diagnosed between 2009 and 2018, were analyzed. The median age was 66 years old (60-90), 72% had advanced disease, 62% had a high IPS, and 49% had a nodular sclerosis subtype. Median follow-up was 64 months for alive patients. ABVD was the front-line treatment in 96% of patients. Twenty-one patients (15%) died during front-line treatment. The 5-year PFS and 5-year OS rates were 55% and 59%, respectively. The 5-year OS rates in localized and advanced disease were 81% and 51% (p=0.013). Lung toxicity developed in 11% of the patients treated with ABVD. Bleomycin was administered for > 2 cycles in 65% of patients. Compared with 2009-2014, there was a decrease in the use of bleomycin for > 2 cycles in 2015-2018 (88% × 45%, p<0.0001). The impact of socioeconomic status (SES) on outcomes was studied in patients treated with ABVD. After adjusting for potential confounders, lower SES remained independently associated with poorer survival (HR 2.22 [1.14-4.31] for OS and HR 2.84 [1.48-5.45] for PFS). Treatment outcomes were inferior to those observed in developed countries. These inferior outcomes were due to an excess of deaths during front-line treatment and the excessive use of bleomycin. SES was an independent factor for shorter survival.

RESUMO

Socioeconomic status (SES) is a well-known determinant of outcomes in cancer. The purpose of this study was to analyze the impact of the SES on the outcomes of Hodgkin lymphoma (HL) patients from the Brazilian Prospective HL Registry. SES stratification was done using an individual asset/education-based household index. A total of 624 classical HL patients with diagnosis from January/2009 to December/2014, and treated with ABVD (doxorubicin, bleomycin, vinblastine and dacarbazine), were analyzed. The median follow-up was 35.6 months, and 33% were classified as lower SES. The 3-year progression- free survival (PFS) in higher and lower SES were 78 and 64% (p < 0.0001), respectively. The 3-year overall survival (OS) in higher and lower SES were 94 and 82% (p < 0.0001), respectively. Lower SES patients were more likely to be ≥ 60 years (16 vs. 8%, p = 0.003), and to present higher risk International Prognostic score (IPS) (44 vs. 31%, p = 0.004) and advanced disease (71 vs. 58%, p = 0.003). After adjustments for potential confounders, lower SES remained independently associated with poorer survival (HR = 3.12 [1.86-5.22] for OS and HR = 1.66 [1.19-2.32] for PFS). The fatality ratio during treatment was 7.5 and 1.3% for lower and higher SES (p = 0.0001). Infections and treatment toxicity accounted for 81% of these deaths. SES is an independent factor associated with shorter survival in HL in Brazil. Potential underlying mechanisms associated with the impact of SES are delayed diagnosis and poorer education. Educational and socio-economic support interventions must be tested in this vulnerable population.

RESUMO

Data about Hodgkin lymphoma (HL) in developing countries are scarce and suggest the existence of substantial disparities in healthcare and outcomes in large areas of the world. In 2009, a prospective registry of HL was implemented in Brazil. Web-based data were contributed by 20 institutions across the country participating in the Brazilian Prospective Hodgkin's Lymphoma Registry. The aim of this study was to present the clinical features and outcomes of newly diagnosed patients with HL aged 13 to 90 years. Multivariate Cox regression models were used to estimate progression-free (PFS) and overall survival (OS) by clinical factors. A total of 674 patients with classical HL were analysed, with a median follow-up of 37 months. Median age was 30 years (13-90). The median time from the onset of symptoms to diagnosis was 6 months (0-60). Only 6% of patients had early favourable disease, while 65% had advanced disease. Stage IVB was present in 26% and a high-risk International Prognostic Score in 38%. Doxorubicin, bleomycin, vinblastine, and dacarbazine was used in 93%. The median dose of radiotherapy was 36 Gy for localized disease and 32 Gy for advanced disease. The 3 year PFS in early favourable, early unfavourable, and advanced disease were 95%, 88%, and 66%, respectively. High-risk International Prognostic Score, advanced disease, and age greater than or equal to 60 were independently associated with poorer PFS and OS; performance status greater than or equal to 2 was also associated with a poorer OS. Poor-risk patients predominated. Radiation doses for localized disease appear higher than current recommendations. Outcomes appear inferior in developing countries than in developed countries. Delayed diagnosis is probably a major factor underlying these findings. Scattered reports from developing nations suggest that many aspects of standard care in developed countries remain unmet needs for populations living in developing countries. The present report contributes to this body of data, with a proper description of what is currently achieved in urban areas in Brazil.

RESUMO

Paciente de 16 anos, sexo masculino, com vírus da imunodeficiência humana (HIV) negativo e sem doença hematológica prévia, desenvolveu anemia acentuada devido à infecção por parvovírus B19. A doença apresentou evolução bifásica, com acalmia clínica e retorno dos sintomas após 15 dias. Ao exame físico, apresentava-se descorado e febril, sem adeno e organomegalias, com sinais de insuficiência cardíaca. O aspirado de medula óssea mostrava megaloblastos com nucléolos aberrantes e, na histologia, foram observadas células gigantes com nucleolação aberrante e presença do corpúsculo de inclusão nuclear típico da parvovirose. O exame de imuno-histoquímica mostrou positividade para anticorpo específico para parvovírus. A sorologia comprovou a infecção.


A 16-year-old human immunodeficiency virus (HIV) negative male patient without hematological disease developed acute anemia due to parvovirus B19 infection. The disease showed a biphasic evolution: clinical remission and return of symptoms after 15 days. Physical examination revealed paleness and fever, neither adeno nor organomegalies, and signs of heart failure. The bone marrow aspiration showed megaloblasts with aberrant nucleoli. As far as histology is concerned, giant cells with aberrant nucleoli and the presence of intranuclear inclusions typical of Parvoviruses were observed. Immunohistochemistry revealed positivity for specific Parvovirus antibody. Serology confirmed parvovirus B19 infection.
