## TL;DR

This study evaluates the safety and effectiveness of allogeneic stem cell transplants in treating a specific type of blood cancer.

## Contribution

The paper provides clinical evidence on allo-HSCT outcomes for BCR::ABL-negative neutrophilic myeloid neoplasms.

## Key findings

- 12 patients achieved successful stem cell engraftment with median granulocyte and platelet recovery times of 17 and 15 days.
- Two-year overall survival was 65.6%, with a 41.7% disease-free survival rate.
- GVHD occurred in some patients, but allo-HSCT was deemed safe and effective.

## Abstract

评价异基因造血干细胞移植（allo-HSCT）治疗BCR::ABL阴性中性粒细胞增殖性肿瘤的疗效及安全性。

纳入2017年3月至2024年6月在北京大学人民医院接受allo‑HSCT治疗的12例中性粒细胞增殖性肿瘤患者，其中慢性中性粒细胞白血病（CNL）8例，骨髓增生异常/骨髓增生性肿瘤伴有中性粒细胞增多（MDS/MPN-N）4例，男7例，女5例，中位年龄48（IQR：28，59）岁，对其临床资料进行回顾性分析。

12例患者中6例接受HLA 10/10同胞全相合造血干细胞移植，6例接受单倍体造血干细胞移植。12例患者均获得粒细胞和血小板植入，粒细胞植活中位时间为17（IQR：11，24）d，血小板植活中位时间为15（IQR：9，28）d。2例患者发生Ⅱ～Ⅳ度急性移植物抗宿主病（GVHD），4例患者发生慢性GVHD。中位随访时间为637（IQR：330，943）d，移植后2年总生存率为（65.6±16.4）％，无病生存率为（41.7±16.6）％，累积复发率为（47.2±18.2）％，移植相关死亡率为（11.1±11.4）％。1例患者移植后死于新型冠状病毒肺炎，2例死于复发。

allo-HSCT是BCR::ABL阴性中性粒细胞增殖性肿瘤安全、有效的治疗方法。
