RESUMO
Mucosa-associated lymphoid tissue (MALT) is the most common extranodal lymphoma, with one third of the cases occurring in the stomach. Surgical treatment is a possible option. This case report describes an obese woman (body mass index 46 kg/m2) seeking bariatric surgery, with elevated serum cholesterol and uric acid, negative for Helicobacter pylori but with a positive biopsy for MALT (immunohistochemistry), stage IA. She was submitted to a Roux-en-Y gastric bypass and gastric resection. Two months later, she had lost 20 kg and the MALT lymphoma was in complete remission.

Os autores sumarizam três experiências brasileiras publicadas ou apresentadas em eventos científicos com a utilização do transplante de medula óssea no tratamento das leucemias agudas, mielóide e linfóide. Estes estudos foram fruto de levantamentos realizados em 16 centros brasileiros de TMO através de questionários padronizados. As análises foram, portanto, retrospectivas. O número de pacientes nestes estudos foi superior a 1000, em torno de 700 na LMA e 400 na LLA. Os resultados, apesar das limitações metodológicas, mostram a factibilidade do procedimento em nossa realidade e respostas de curto e longo prazo adequadas. Os estudos auxiliaram ainda no reconhecimento de limites estruturais, como a pouca disponibilidade da citogenética em nosso meio e a necessidade de estudos prospectivos e controlados neste grupo de pacientes.
Te authors summarized three Brazilian experiences published or presented in scientific meetings, using bone marrow transplantation in the treatment of acute myeloid or lymphoid leukemia. These studies were performed using a standard questionnaire applied in 16 Brazilian centers. The analysis was retrospective. The number of analyzed patients was about of 1000, about 700 AML and 400 ALL. Although the methodological limitation the studies showed the feasibility of procedure in our reality. The responses and long term outcome were acceptable compared to international data. The studies helped us to recognize structural limitation as availability of cytogenetic laboratories. Prospective and controlled studies are needed in this setting of patients in Brazil.
