RESUMEN
O linfoma de células T angioimunoblástico (AITL) é subtipo raro de linfoma de células T periférico que representa cerca de 2% dos linfomas não Hodgkin (LNH). Acomete predominantemente homens, na sexta e sétima décadas de vida e se apresenta como doença sistêmica. É agressivo no comportamento e responde mal à quimioterapia, com tratamento padrão ainda não definido. Este relato objetiva apresentar o prognósticodesfavorável nos pacientes com AITL e a falta de consolidação de seu tratamento. Os fatores que podem estar associados à má-resposta são: idoso, estágios avançados e sintomatologia constitucional.
Angioimmunoblastic T-cell lymphoma (AITL) is a rare subtype of peripheral T-cell lymphoma that represents about 2% of non-Hodgkin?s lymphomas (LNH). It affects mainly men, in the sixth and seventh decades of life, and appears as a systemic disease. It has an aggressive behavior and responds poorly to chemotherapy, still with undefined standard treatment. This report aims to provide the poor prognosis in patients with AITLand the lack of treatment consolidation. The factors that may be associated with the poor response are being elderly, advanced stages, and constitutional symptoms.
RESUMEN
Background: The most common types of non-Hodgkin lymphoma (NHL) are diffuse large B cell (DLBCL) and follicular (FL). Aim: To analyze the benefit ofRituxi-mab in overall survival (OS) of patients with NHL. Material and Methods: Review of medical record of 230 adult patients with afirst episode of NHL admitted between 2002 and 2011. We included 67 patients with DLBCL and 36 patients with FL. Results: The overall response (OR) was 64% with 39% complete remissions (CR) in DLBCL treated with CHOP-like and 100% with 89% CR with R-CHOP. The median OS with CHOP-like was 21 months versus not attained R-CHOP (p = 0.016). There was a statistically significant difference in median event-free survival (EvFS) in favor of R-CHOP: not attained versus 8.3 months for CHOP-like (log rank (p = 0.002)). In FL, the OR in patients treated with R-CHOP or R-CHOP-like was 85%) with 54% CR. With CHOP-like the OR was 59%> with 18% CR. The OS at 24 and 36 months in patients treated with R-CHOP or R-CHOP-like was 83 and 65%. The figures for patients treated with CHOP-like were 80 and 66%> respectively. The progression free survival (PFS) was 21 months with CHOP-like versus not attained with R-QT (p = 0,043). Conclusions: When Rituximab was added to CHOP, there was a higher CR, EvFS and OS in DLBCL and higher CR and PFS in FL.
