Aspirin and statin use may lower the risk of advanced/fatal prostate cancer, possibly by reducing intraprostatic inflammation. To test this hypothesis, we investigated the association of aspirin and statin use with the presence and extent of intraprostatic inflammation, and the abundance of specific immune cell types, in benign prostate tissue from a subset of men from the placebo arm of the Prostate Cancer Prevention Trial. Men were classified as aspirin or statin users if they reported use at baseline or during the 7-year trial. Presence and extent of inflammation were assessed, and markers of specific immune cell types (CD4, CD8, FoxP3, CD68, and c-KIT) were scored, in slides from end-of-study prostate biopsies taken irrespective of clinical indication, per trial protocol. Logistic regression was used to estimate associations between medication use and inflammation measures, adjusted for potential confounders. Of 357 men included, 61% reported aspirin use and 32% reported statin use. Prevalence and extent of inflammation were not associated with medication use. However, aspirin users were more likely to have low FoxP3, a T regulatory cell marker [OR, 5.60; 95% confidence interval (CI), 1.16–27.07], and statin users were more likely to have low CD68, a macrophage marker (OR, 1.63; 95% CI, 0.81–3.27). If confirmed, these results suggest that these medications may alter the immune milieu of the prostate, which could potentially mediate effects of these medications on advanced/fatal prostate cancer risk.

阿司匹林和他汀类药物在前列腺癌预防试验安慰剂组良性前列腺组织炎症中的应用

阿司匹林和他汀类药物的使用可能会降低晚期/致命前列腺癌的风险,可能是通过减少前列腺内炎症。为了验证这一假设,我们在来自前列腺癌预防安慰剂组的一部分男性的良性前列腺组织中研究了阿司匹林和他汀类药物的使用与前列腺内炎症的存在和程度以及特定免疫细胞类型的丰度之间的关联审判。如果男性在基线或 7 年试验期间报告使用过阿司匹林或他汀类药物,则被归类为阿司匹林或他汀类药物使用者。评估炎症的存在和程度,并对特定免疫细胞类型(CD4、CD8、FoxP3、CD68 和 c-KIT)的标记物进行评分,无论临床指征如何,每项试验均在研究结束前列腺活检的载玻片中进行评分协议。Logistic 回归用于估计药物使用和炎症测量之间的关联,并针对潜在的混杂因素进行调整。在包括的 357 名男性中,61% 报告使用阿司匹林,32% 报告使用他汀类药物。炎症的患病率和程度与药物使用无关。然而,阿司匹林使用者更有可能具有较低的 FoxP3,一种 T 调节细胞标志物 [OR,5.60;95% 置信区间 (CI),1.16–27.07],他汀类药物使用者更有可能具有低 CD68,一种巨噬细胞标志物(OR,1.63;95% CI,0.81–3.27)。如果得到证实,这些结果表明这些药物可能会改变前列腺的免疫环境,这可能会介导这些药物对晚期/致命前列腺癌风险的影响。61% 报告使用阿司匹林,32% 报告使用他汀类药物。炎症的患病率和程度与药物使用无关。然而,阿司匹林使用者更有可能具有较低的 FoxP3,一种 T 调节细胞标志物 [OR,5.60;95% 置信区间 (CI),1.16–27.07],他汀类药物使用者更有可能具有低 CD68,一种巨噬细胞标志物(OR,1.63;95% CI,0.81–3.27)。如果得到证实,这些结果表明这些药物可能会改变前列腺的免疫环境,这可能会介导这些药物对晚期/致命前列腺癌风险的影响。61% 报告使用阿司匹林,32% 报告使用他汀类药物。炎症的患病率和程度与药物使用无关。然而,阿司匹林使用者更有可能具有较低的 FoxP3,一种 T 调节细胞标志物 [OR,5.60;95% 置信区间 (CI),1.16–27.07],他汀类药物使用者更有可能具有低 CD68,一种巨噬细胞标志物(OR,1.63;95% CI,0.81–3.27)。如果得到证实,这些结果表明这些药物可能会改变前列腺的免疫环境,这可能会介导这些药物对晚期/致命前列腺癌风险的影响。和他汀类药物使用者更有可能具有低 CD68,一种巨噬细胞标志物(OR,1.63;95% CI,0.81–3.27)。如果得到证实,这些结果表明这些药物可能会改变前列腺的免疫环境,这可能会介导这些药物对晚期/致命前列腺癌风险的影响。和他汀类药物使用者更有可能具有低 CD68,一种巨噬细胞标志物(OR,1.63;95% CI,0.81–3.27)。如果得到证实,这些结果表明这些药物可能会改变前列腺的免疫环境,这可能会介导这些药物对晚期/致命前列腺癌风险的影响。
