Median OS time and PFS time were not reached. During this period, only 3 patients died, but none of them died directly due to disease progression. One patient(1.6%) developed transformation to diffuse large B-cell lymphoma(DLBCL). Of the 56 patients achieved complete remission after first-line treatment, 5(8.9%) developed local and/or systemic relapse eventually. Patients ≥60 y had significantly shorter PFS than younger patients(P=0.01). For patients with early stages(Ann Arbor stage I and stage II), univariate analysis confirmed that radiotherapydose lower than 32 Gy were independently associated with shorter PFS(P=0.04). Other factors including gender, bone marrow involvement, the initial location of the disease, and the laterality were not associated with PFS.CONCLUSION: The data from our center indicate that POAML has a slow clinical progression and has an excellent clinical outcome. Patients with POAML harbor a continual risk of relaps and transformation to aggressive subtype of lymphoma.展开更多

Diversity of AEG-1 and LEF-1 expressions in different Ann Arbor clinical stages showed a statistically significant result（P〈0.05）. A positive relevance between AEG-1 and LEF-1 was observed in MALT ocular adnexal lymphoma（r=0.435, P=0.016）.CONCLUSION：The over expressions of AEG-1 and LEF-1 at the level of protein and mR NA participates in the tumorigenesis of ocular adnexal MALT lymphoma. They should act as a new biological marker for pathological diagnosis in the future.展开更多
