Abstract

Prostate cancer (PCa) is a prevalent malignancy in men globally. Current diagnostic methods like PSA testing have limitations, leading to overdiagnosis and unnecessary treatment. Castration-resistant prostate cancer (CRPC) emerges in some patients receiving androgen deprivation therapy (ADT). This study explores the potential of circulating microRNA-107 (miR-107) in liquid biopsies as a prognosis tool to differentiate CRPC from non-castration-resistant PCa (NCRPC). We designed a case-control study to evaluate circulating miR-107 in serum as a potential prognosis biomarker. We analyzed miR-107 expression in liquid biopsies and found significantly higher levels (p < 0.005) in CRPC patients, compared to NCRPC. Notably, miR-107 expression was statistically higher in the advanced stage (clinical stage IV), compared to stages I-III. Furthermore, CRPC patients exhibited significantly higher miR-107 levels (p < 0.05), compared to NCRPC. These findings suggest that miR-107 holds promise as a non-invasive diagnostic biomarker for identifying potential CRPC patients.

循环 miR-107 作为阉割耐药前列腺癌的一种潜在生物标记物

前列腺癌（PCa）是全球普遍存在的男性恶性肿瘤。目前的诊断方法（如 PSA 检测）存在局限性，导致过度诊断和不必要的治疗。一些接受雄激素剥夺疗法（ADT）的患者会出现阉割抗性前列腺癌（CRPC）。本研究探讨了液体活检中循环microRNA-107（miR-107）作为预后工具的潜力，以区分CRPC和非阉割耐药PCa（NCRPC）。我们设计了一项病例对照研究，以评估血清中作为潜在预后生物标志物的循环 miR-107。我们分析了液体活检中的 miR-107 表达，发现 CRPC 患者的 miR-107 表达水平明显高于 NCRPC（P < 0.005）。值得注意的是，与I-III期相比，晚期（临床IV期）患者的miR-107表达在统计学上更高。此外，与 NCRPC 相比，CRPC 患者的 miR-107 水平明显更高（p < 0.05）。这些研究结果表明，miR-107有望成为识别潜在CRPC患者的非侵入性诊断生物标志物。
