Extramedullary disease (EMD) is a rare manifestation of Waldenström macroglobulinemia (WM), and its clinical and prognostic implications are poorly understood.
In this single-center study, we investigated the clinical significance of EMD in a cohort of 469 WM patients.
EMD was identified in 30 (6.4%) patients, with the central nervous system, kidneys, and lungs being the most frequently affected sites. The cumulative incidence of EMD was 12.6% at 15 years. Median overall survival rates at 5 and 10 years for patients with EMD were 63% and 37%, respectively.
Our findings indicate a persistent risk of EMD throughout the disease course, with no significant impact on long-term survival.
髓外疾病（EMD）是华氏巨球蛋白血症（WM）的一种罕见表现，其临床和预后意义尚不清楚。
在这项单中心研究中，我们调查了469例WM患者队列中EMD的临床意义。
30例（6.4%）患者被诊断为EMD，中枢神经系统、肾脏和肺部是最常受累的部位。15年时EMD的累积发病率为12.6%。EMD患者5年和10年的中位总生存率分别为63%和37%。
我们的研究结果表明，在整个疾病过程中EMD存在持续风险，对长期生存无显著影响。
