Abstract

The characteristics of the very rare non-treatment-related chronic myeloid leukemia (nTr-CML) cases have never before been analyzed. The literature up to December 2002 was screened using the Medline database to identify cases of Tr-CML and nTr-CML. We considered five cases with nTr-CML identified among 270 newly diagnosed CML at our Department. Our report thus considers nine cases with nTr-CML compared to 77 affected by Tr-CML as a secondary neoplasm. The median age at the appearance of the first tumor was higher in nTr-CML patients compared to that of the Tr-CML group (P<0.0001). The median age at CML diagnosis was significantly higher in the nTr-CML than in the Tr-CML group (P<0.0001). The proportion of hematological malignancies as first tumor type was not different in the two groups (44% in nTr-CML versus 56% in Tr-CML). Our study underlines that nTr-CML as a second malignancy is a rare entity associated with elderly age.

摘要

此前从未对极为罕见的非治疗相关慢性粒细胞白血病（nTr-CML）病例的特征进行过分析。利用Medline数据库筛选了截至2002年12月的文献，以确定治疗相关慢性粒细胞白血病（Tr-CML）和非治疗相关慢性粒细胞白血病（nTr-CML）的病例。我们在本部门新诊断的270例慢性粒细胞白血病中发现了5例nTr-CML。因此，我们的报告中纳入了9例nTr-CML病例，与之相比，有77例受Tr-CML影响的病例为继发性肿瘤。与Tr-CML组相比，nTr-CML患者首次出现肿瘤时的中位年龄更高（P<0.0001）。nTr-CML组慢性粒细胞白血病诊断时的中位年龄显著高于Tr-CML组（P<0.0001）。两组中作为首发肿瘤类型的血液系统恶性肿瘤比例无差异（nTr-CML组为44%，Tr-CML组为56%）。我们的研究强调，nTr-CML作为第二种恶性肿瘤是一种与老年相关的罕见疾病。
