Classificação dos tumores hematopoéticos e linfoides de acordo com a OMS: padronização da nomenclatura em língua portuguesa, 4ª edição / Classification of haematopoietic and lymphoid tumors: WHO, standardization of nomenclature in Portuguese, 4th edition

INTRODUÇÃO: A classificação da Organização Mundial da Saúde (OMS) para os tumores do tecido hematopoético e linfoide (4ª edição, 2008) representa uma revisão atualização da 3ª edição publicada em 2001. A tradução da nomenclatura utilizada para identificar as entidades descritas deve ser clara, precisa e uniforme no sentido de reproduzir de forma correta as diversas entidades clinicopatológicas para clínicos, patologistas e pesquisadores envolvidos na área da onco-hematopatologia. OBJETIVO: Os autores apresentam uma proposta de atualização e padronização terminológica em língua portuguesa, com base na OMS/2008.

INTRODUCTION: The World Health Organization (WHO) classification of hematopoietic and lymphoid tissue (4th edition, 2008) tumors constitutes an updated review of the 3rd edition published in 2001. The translation of the nomenclature used to describe the entities should be clear, precise and uniform so that clinicians, pathologists and researchers involved in the onco-hematopathological area may identify them accurately. OBJECTIVE: With this purpose, the authors present an updated proposal and a terminological standardization in Portuguese based on WHO/2008.

Prognostic factors in non-Hodgkin lymphomas

CONTEXT: In Hodgkin's disease, each clinical or pathologic stage can be related to the extent of the area involved and predicts the next anatomical region at risk for tumor dissemination. OBJECTIVE: To determine the best prognostic factors that could predict survival in non-Hodgkin lymphoma cases. DESIGN: A retrospective study. LOCATION: Department of Hematology and Transfusion Medicine, Universidade Federal de São Paulo - Escola Paulista de Medicina. PARTICIPANTS: 142 patients with non-Hodgkin lymphoma diagnosed between February 1988 and March 1993. MAIN MEASUREMENTS: Histological subset, Sex, Age, Race, B symptoms, Performance status, Stage, Extranodal disease, Bulk disease, Mediastinal disease, CNS involvement, BM infiltration, Level of DHL, Immunophenotype. RESULTS: In the first study (113 patients), the following variables had a worse influence on survival: yellow race (P<0.1); ECOG II, III e IV (P<0.1) and extranodal disease (P<0.1) for high grade lymphomas; constitutional symptoms (P<0.1), ECOG II, III e IV (P<0.1) and involvement of CNS (P<0.1) for intermediate grade and the subtype lymphoplasmocytoid (P=0.0186) for low grade lymphomas. In the second survey (93 patients), when treatment was included, the variables related to NHL survival were: CNS involvement (P<0.1) for high grade lymphomas, constitutional symptoms (P<0.1), ECOG II, III, IV (P=0.0185) and also CNS involvement (P<0.1) for the intermediate group. There were no variables related to the survival for low-grade lymphomas. CONCLUSIONS: The intermediate grade lymphomas were more compatible with data found in the literature, probably because of the larger number of patients. In this specific case, the treatment did not have an influence on the survival

Linfoma primario da bexiga apos transplante renal / Primary lymphoma of bladder secundary to renal transplantation

Linfoma primario da bexiga e uma doença rara e corresponde a menos de 1 por cento das neoplasias vesicais. Em pacientes transplantados, o risco de adquiri-lo como complicaçoes da imunossupressao e 350 vezes aquele da populaçao geral. Nesse artigo, fazemos revisao da literatura e relatamos um caso de linfoma nao-Hodgkin primario da bexiga, em um paciente do sexo masculino, que surgiu dois meses apos o transplante renal usando esquema triplice de imunossupressao (ciclosporina, azatioprina e prednisona), o mesmo regrediu apos tratamento com quimioterapia e suspensao parcial da imunossupressao
