## TL;DR

This study identifies key prognostic factors for primary plasma cell leukemia in the era of novel treatments, including treatment response and high calcium levels.

## Contribution

The study identifies novel independent prognostic factors for primary plasma cell leukemia in the context of modern therapies.

## Key findings

- Patients achieving ≥VGPR had significantly longer OS and PFS compared to those with ≤PR.
- Maintenance therapy significantly improved OS and PFS in pPCL patients.
- Hypercalcemia was identified as an independent risk factor for poor OS in pPCL.

## Abstract

探讨新药时代原发性浆细胞白血病（pPCL）的预后因素。

回顾性收集2011年至2022年就诊于首都医科大学附属北京朝阳医院血液科66例pPCL患者的临床资料，分析其预后因素。

66 例pPCL患者中位发病年龄为59（29～79）岁。中位总生存（OS）期为19.0（95％CI 10.4～27.6）个月，中位无进展生存（PFS）期为11.0（95％CI 6.5～15.6）个月。治疗后最佳疗效≥非常好的部分缓解（VGPR）患者的中位OS期和PFS期均显著长于疗效≤部分缓解（PR）患者（中位OS期：33.0个月对6.0个月，P<0.001；中位PFS期：16.0个月对3.0个月，P<0.001）。接受自体造血干细胞移植患者的OS期较未接受患者显著延长（49.0个月对6.0个月，P＝0.002），PFS期也有延长趋势（19.0个月对8.0个月，P＝0.299）。接受维持治疗患者的中位OS期、PFS期较未接受维持治疗患者显著延长（中位OS期：56.0个月对4.0个月，P<0.001；中位PFS期：20.0个月对2.0个月，P<0.001）。多因素分析结果表明，高钙血症是影响pPCL患者OS的独立危险因素（HR＝3.204，95％CI 1.068～9.610，P＝0.038）；接受维持治疗（HR＝0.075，95％CI 0.022～0.253，P<0.001）、治疗后疗效≥VGPR（HR＝0.175，95％CI 0.048～0.638，P＝0.008）是影响pPCL患者OS的独立保护因素。

在新药时代，高钙血症、接受维持治疗、治疗后疗效≥VGPR是pPCL的独立预后因素。
