This study sought to estimate the severity, etiology, and clinical importance of treatment-related lymphopenia in patients with stage III non-small-cell lung cancer.
Serial lymphocyte counts and survival were analyzed retrospectively in 47 patients accounting for known prognostic factors.
Total lymphocyte counts (TLCs) were normal before therapy and did not change following neoadjuvant chemotherapy. Following radiation, TLC fell by 67% (median 500 cells/mm(3), p <.00001). Multivariate analysis revealed an association between severe TLC and survival (HR 1.70, 95% CI: 0.8-3.6).
Rapid and severe lymphopenia occurred in 50% of patients following radiation which was associated with reduced survival.
本研究旨在评估 III 期非小细胞肺癌患者治疗相关性淋巴细胞减少症的严重程度、病因和临床意义。
对 47 例已知预后因素的患者进行回顾性分析,检测其淋巴细胞计数和生存情况。
治疗前总淋巴细胞计数(TLC)正常,新辅助化疗后无变化。放疗后,TLC 下降 67%(中位数 500 细胞/mm³,p<0.00001)。多变量分析显示,严重的 TLC 与生存相关(HR 1.70,95%CI:0.8-3.6)。
放疗后 50%的患者出现快速且严重的淋巴细胞减少症,与生存降低有关。
