摘要

背景:典型慢性髓系白血病(aCML)是一种罕见的侵袭性骨髓增生异常综合征/骨髓增生性肿瘤。本研究旨在全面了解aCML患者的流行病学、临床特征和生存结局。方法本研究利用2001年至2020年监测、流行病学和最终结果(SEER)数据库的数据。计算aCML的年龄调整发生率(AIR),并采用Kaplan-Meier法和加速失效时间(AFT)回归分析生存结局。结果aCML的AIR为0.024 / 10万人-年,以2020年发生率最高。aCML的发病率随着年龄的增长而增加,男性发病率较高。研究队列主要由老年白人个体组成,平均诊断年龄为68.2±15.3岁。中位总生存期(OS)和疾病特异性生存期(DSS)分别为1.4年和1.7年。年龄越大与生存结果越差独立相关。值得注意的是,治疗延迟和化疗对OS或DSS没有显著影响。结论本研究对aCML的流行病学、临床特征和生存结果提供了全面的见解,突出了其罕见性、侵袭性和预后差。需要进一步的研究来验证这些发现,并探索新的治疗策略来改善这种具有挑战性的血液恶性肿瘤的预后。

Comprehensive analysis of Atypical chronic myeloid leukemia (aCML): Epidemiology, clinical features, and survival outcomes based on SEER database insights

Background

Atypical Chronic Myeloid Leukemia (aCML) is a rare and aggressive myelodysplastic syndrome/myeloproliferative neoplasm. This study aimed to provide a comprehensive understanding of the epidemiology, clinical characteristics, and survival outcomes of aCML patients.

Methods

The study utilized data from the Surveillance, Epidemiology, and End Results (SEER) database from 2001 to 2020. The age-adjusted incidence rate (AIR) of aCML was calculated, and survival outcomes were analyzed using the Kaplan-Meier method and accelerated failure time (AFT) regression analysis.

Results

The AIR of aCML was found to be 0.024 per 100,000 person-years, with the highest rate observed in 2020. The incidence of aCML increased with age and was higher in males. The study cohort predominantly consisted of elderly White individuals, with an average age at diagnosis of 68.2 ± 15.3 years. The median overall survival (OS) and disease-specific survival (DSS) were 1.4 years and 1.7 years, respectively. Older age was independently associated with worse survival outcomes. Notably, treatment delay and chemotherapy did not significantly impact OS or DSS.

Conclusions

This study provides comprehensive insights into the epidemiology, clinical characteristics, and survival outcomes of aCML, highlighting its rarity, aggressive nature, and poor prognosis. Further research is needed to validate these findings and explore novel therapeutic strategies for improving outcomes in this challenging hematologic malignancy.
