# Clinical characteristics of myeloid tumors combined with the proliferation of large granular lymphocytes

## TL;DR

This paper studies a rare condition where myeloid tumors co-occur with large granular lymphocyte proliferation, finding specific clinical features and genetic mutations linked to patient outcomes.

## Contribution

The study identifies clinical and genetic characteristics of myeloid neoplasms combined with large granular lymphocyte proliferation, a rare and understudied condition.

## Key findings

- MN-LGLP patients are more likely to have neutropenia and splenomegaly.
- LGLP presence does not affect survival in MN-LGLP patients.
- STAG2, ASXL1, and TET2 are common mutations, with STAG2 mutations linked to worse prognosis.

## Abstract

髓系肿瘤（MN）为一组造血干祖细胞生物学功能异常的血液系统恶性肿瘤。越来越多的证据表明，MN患者异常的免疫、造血微环境与恶性克隆性造血干细胞相互作用，促进其疾病的发生、发展。髓系肿瘤伴大颗粒淋巴细胞增殖（Myeloid neoplasms-large granular lymphocyte proliferation, MN-LGLP）为此类疾病中的一种特殊罕见的临床现象，目前国内外对本病的队列研究较少，本研究分析该类患者的临床和实验室特征，探讨影响LGLP对MN患者临床特征和生存的影响。提示MN-LGLP患者更易出现中性粒细胞减少及脾大。LGLP的存在不是影响MN-LGLP患者生存的危险因素。STAG、ASXL1、TET2是MN-LGLP最常见的伴随基因突变，伴有STAG2突变MN-LGLP患者预后较差。
