脑转移(BrM)是与癌症相关死亡率相关的主要问题,目前,在临床环境中没有特异性生物标志物可用于早期检测。液体活检被广泛接受为诊断癌症和其他疾病的非侵入性方法。我们已经审查了证据,表明分子改变如何参与BrM,主要来自乳腺癌(BC),肺癌(LC)和黑色素瘤,以及如何将其用于生物标志物开发的开端。我们讨论了影响癌细胞突破血脑屏障(BBB)并有助于在独特的脑微环境中建立转移性病变的遗传和表观遗传变化。与各种生物分子检测和鉴定背景下的最新突破保持同步,可以在人体流体如血液、血清、脑脊液(CSF)和尿液中追踪循环肿瘤细胞(CTC)、无细胞核苷酸、非编码RNA、分泌蛋白和代谢物,以获得用于生物标志物开发的潜在候选物。基于液体活检的生物标志物可以与当前的成像技术重叠,以放大信号,从而改善隐匿性BrM的早期检测和治疗。
Brain metastasis (BrM) is a major problem associated with cancer-related mortality, and currently, no specific biomarkers are available in clinical settings for early detection. Liquid biopsy is widely accepted as a non-invasive method for diagnosing cancer and other diseases. We have reviewed the evidence that shows how the molecular alterations are involved in BrM, majorly from breast cancer (BC), lung cancer (LC), and melanoma, with an inception in how they can be employed for biomarker development. We discussed genetic and epigenetic changes that influence cancer cells to breach the blood-brain barrier (BBB) and help to establish metastatic lesions in the uniquely distinct brain microenvironment. Keeping abreast with the recent breakthroughs in the context of various biomolecules detections and identifications, the circulating tumor cells (CTC), cell-free nucleotides, non-coding RNAs, secretory proteins, and metabolites can be pursued in human body fluids such as blood, serum, cerebrospinal fluid (CSF), and urine to obtain potential candidates for biomarker development. The liquid biopsy-based biomarkers can overlay with current imaging techniques to amplify the signal viable for improving the early detection and treatments of occult BrM.
