摘要: 背景儿童急性髓细胞白血病(AML)是一种高度异质性疾病,但关于AML患儿民族差异与临床关系的研究鲜有报道。目的分析云南地区AML(非M3型)患儿的临床特征及预后,并探究其民族差异。方法收集2015-01-01至2020-03-01昆明市儿童医院收治的初诊AML(非M3型)患儿为研究对象。收集AML患儿的基线临床资料,包括人口学资料(民族、性别、年龄)、一般资料(白细胞计数、血红蛋白、血小板计数、乳酸脱氢酶、骨髓原始细胞数、FAB分型)、染色体核型结果、基因检测结果。从所有患儿入组后开始随访,截至2020-05-31。记录患儿的治疗方案、危险度及预后情况。结果最终纳入AML(非M3型)患儿72例,随访时间为2~60个月;汉族51例,少数民族21例(彝族5例、回族4例、哈尼族3例、白族2例、苗族2例、壮族1例、佤族1例、布依族1例、蒙古族1例、傣族1例)。少数民族患儿白细胞计数高于汉族(P<0.05)。随访截至2020-05-31,汉族和少数民族患儿诱导治疗第一疗程后完全缓解率、复发率、骨髓移植率比较,差异无统计学意义(P>0.05);少数民族患儿危险度、死亡率高于汉族(P<0.05)。随访截至2020-05-31,绘制汉族和少数民族AML患儿的生存曲线进行比较,汉族AML患儿无事件生存率、总生存率高于少数民族(χ2值分别为8.098、12.547,P值分别为0.004、<0.001)。结论云南地区汉族AML患儿危险度分层、预后优于少数民族,但具体原因尚未明确。

Abstract: Background

Childhood acute myeloid leukaemia (AML) is a higly heterogenous disorder. But its clinical characteristics according to ethic groups have been rarely studied.

Objective

To explore ethnic-specific clinical characteristics and prognosis of paediatric patients with non-M3 AML from Yunnan province.

Methods

Paediatric patients with newly diagnosed non-M3 AML were rectuited from Kunming Children's Hospital between January 1, 2015 and March 1, 2020. Basic baseline clinical data, including demographic characteristics (ethnic group, gender, age) , general information (white blood cell count, haemoglobin, platelet count, lactate dehydrogenase, bone marrow blast cell, FAB classification) , karyotype, and genetic information were collected. All patients were followed up from enrolment to 2020-05-31, and treatment protocols, risk stratifications, and prognoses were collected.

Results

Seventy-two cases〔51 cases of Han, 21 cases of minorities (5 Yi, 4 Hui, 3 Hani, 2 Bai, 2 Miao, 1 Zhuang, 1 Wa, 1 Buyi, 1 Mongolian and 1 Dai) 〕 were enrolled, with a follow-up of 2-60 months. Children of ethnic minorities had higher mean white blood cell count did those of Han (P<0.05) . Follow-up analysis showed that compared with children of Han, children of ethnic minorities had higher risk and moratlity (P<0.05) , but domonstrated simailar complete remission rate, recurrence rate and bone marrow transplantation rate after the first course of induction therapy (P>0.05) . Event-free survival rate and overall survival rate of children of Han were higher than those of children of ethnic minorities (χ2=8.098, P=0.004; χ2=12.547, P<0.001) .

Conclusion

Non-M3 AML children of Han had lower risk and better prognosis than those of ethnic minorities in Yunnan, but the reason has not been identified.
