Most follicular lymphomas (FLs) demonstrate an indolent clinical course with favorable outcomes; however, a fraction of patients experiences progression of disease within 24 months (POD24) and has adverse outcomes. This study aimed to determine the predictive risk factors for POD24 in patients with FL, and the characteristics of the microenvironment in FL with POD24. By multivariate analysis, we revealed that increased Ki-67 expression was associated with POD24 events in patients with FL (hazard ratio [HR]: 6.29, 95% confidence interval [CI]: 1.96-20.22, = 0.0020). Additionally, patients with FL with POD24 demonstrated immune cell reduction by immunohistochemistry analysis. Our results help better understand the therapeutic strategies for FL with POD24.
大多数滤泡性淋巴瘤（FL）表现出惰性的临床过程和良好的预后；然而，一部分患者在 24 个月内（POD24）疾病进展，并出现不良结局。本研究旨在确定滤泡性淋巴瘤患者 POD24 的预测风险因素，以及 POD24 滤泡性淋巴瘤的微环境特征。通过多变量分析，我们发现 Ki-67 表达增加与滤泡性淋巴瘤患者的 POD24 事件相关（风险比 [HR]：6.29，95%置信区间 [CI]：1.96-20.22， = 0.0020）。此外，POD24 滤泡性淋巴瘤患者的免疫细胞通过免疫组化分析显示减少。我们的研究结果有助于更好地理解 POD24 滤泡性淋巴瘤的治疗策略。
