Abstract

We report a comparative analysis of patients with therapy-related acute lymphoblastic leukaemia (tr-ALL) vs de novo ALL. We identified 331 patients with B-ALL; 69 (21%) were classified as tr-ALL. The most common prior malignancies were breast (23·2%) and plasma cell disorders (20·3%). Patients with tr-ALL were older (median 63·2 vs. 46·2 years, P < 0.001), more often female (66·7% vs. 43·5%, P < 0·001), and more likely to have hypodiploid cytogenetics (18·8% vs. 5·0%, P < 0·001). In multivariable analysis, patients with tr-ALL were less likely to achieve complete remission [odds ratio (OR) = 0·16, P < 0·001] and more likely to be minimal residual disease-positive (OR = 4·86, P = 0·01) but had similar OS after diagnosis and allo-haematopoietic cell transplantation.

摘要

我们报告了治疗相关急性淋巴细胞白血病(t r - ALL)与初发急性淋巴细胞白血病(de novo ALL)患者的对比分析。我们确定了 331 例 B-ALL 患者;69 例(21%)被归类为 t r - ALL。最常见的既往恶性肿瘤为乳腺癌(23.2%)和浆细胞疾病(20.3%)。t r - ALL 患者年龄更大(中位数 63.2 岁 vs. 46.2 岁,P<0.001),女性比例更高(66.7% vs. 43.5%,P<0.001),且更可能存在亚二倍体细胞遗传学异常(18.8% vs. 5.0%,P<0.001)。多变量分析显示,t r - ALL 患者完全缓解的可能性较低(比值比[OR] = 0.16,P<0.001),微小残留病阳性的可能性较高(OR = 4.86,P=0.01),但在诊断和异体造血细胞移植后,其总生存情况无显著差异。
