目的

探讨CD68+巨噬细胞在肿瘤间质中的浸润水平与ⅠB期肺鳞癌(LUSC)患者术后无病生存期(DFS)之间的关系,评估其作为潜在预后标志物的临床价值。

方法

回顾性分析2014年在中国医学科学院肿瘤医院接受手术切除的60例ⅠB期LUSC患者临床资料,采用CD68免疫组织化学染色及HALO数字病理平台量化肿瘤间质中CD68+细胞表达。根据受试者工作特征(ROC)曲线确定的最佳截断值(12.01)将患者分组,比较不同表达组的DFS,采用单因素及多因素Cox回归模型分析预后影响因素。

结果

中位随访82个月,共21例(35%)发生复发或转移。CD68高表达组的DFS显著优于低表达组(P<0.05)。多因素分析显示,CD68高表达为DFS的独立保护性因素[风险比(HR)=0.179,95%置信区间(CI):0.041~0.775,P=0.021],而脏层胸膜侵犯为不良预后因素(HR=2.865,95%CI:1.18~6.95,P=0.018)。

结论

肿瘤间质中CD68+巨噬细胞高浸润与ⅠB期LUSC患者较长DFS密切相关,提示其为有潜力的预后生物标志物。联合CD68表达水平和传统病理因素,有助于完善术后风险评估和个体化治疗决策。

Objective

To investigate the association between stromal CD68+ macrophage infiltration and disease-free survival (DFS) in patients with stage ⅠB lung squamous cell carcinoma (LUSC) after surgery, and to evaluate its potential as a prognostic biomarker.

Methods

Sixty patients with stage ⅠB LUSC who underwent surgery in 2014 in Cancer Hospital of Chinese Academy of Medical Sciences were retrospectively analyzed. CD68+ macrophages in the tumor stroma were quantified by immunohistochemistry and HALO digital pathology. Based on the optimal cutoff value (12.01) from ROC analysis, patients were divided into high- and low-expression groups. Kaplan-Meier survival analysis and Cox regression models were used to assess DFS and prognostic factors.

Results

After a median follow-up of 82 months, 21 (35%) patients experienced recurrence or metastasis. High CD68 expression was significantly associated with longer DFS (P<0.05). Multivariate Cox regression showed that high CD68 expression was an independent protective factor [hazard ratio (HR) =0.179, 95% confidence interval (CI) : 0.041–0.775, P=0.021], whereas visceral pleural invasion was associated with poorer prognosis (HR=2.865, 95%CI: 1.18–6.95, P=0.018) .

Conclusions

High stromal infiltration of CD68+ macrophages is associated with improved DFS in patients with stage ⅠB LUSC. CD68 may serve as a novel prognostic biomarker, and its integration with traditional pathological factors may enhance postoperative risk stratification and personalized treatment.
