Liquid biopsies represent a significant advancement in oncology, offering a non-invasive means to monitor tumor evolution and guide treatment decisions. By analyzing circulating tumor DNA (ctDNA) and other tumor-derived materials in bodily fluids, this technology enables real-time tracking of genetic alterations, resistance mechanisms, and minimal residual disease (MRD) [1].
This dynamic assessment is critical for personalizing treatment strategies, predicting treatment response, and detecting early relapse, ultimately enhancing patient outcomes in cancer care. Monitoring dynamic changes in ctDNA profiles through liquid biopsies is essential for the early detection of acquired resistance mutations. This capability is particularly vital for patients with advanced cancers, such as non-small cell lung cancer (NSCLC), where resistance to targeted therapies is a common challenge. The non-invasive identification of resistance mechanisms can guide subsequent therapeutic choices and improve clinical management [2].
The prognostic and predictive value of circulating tumor cells (CTCs) and ctDNA in metastatic colorectal cancer (mCRC) is increasingly recognized. Serial monitoring of these markers can effectively reflect tumor burden, treatment efficacy, and the emergence of resistance, facilitating a more personalized approach to managing mCRC that moves beyond static tumor assessments [3].
Detecting minimal residual disease (MRD) after treatment using liquid biopsies marks a key advancement in solid tumor management. For cancers like breast cancer, ctDNA can identify residual disease that might evade detection by imaging. This early identification of MRD is highly predictive of relapse and can inform decisions regarding adjuvant therapy, potentially preventing recurrence [4].
The evolution of tumor heterogeneity presents a major challenge in cancer treatment. Liquid biopsies, through serial ctDNA analysis, offer a valuable insight into this dynamic process. By capturing the genetic diversity within a tumor over time, it becomes possible to understand tumor adaptation to therapy and the development of resistance, leading to more effective and adaptive treatment plans [5].
In the context of prostate cancer, ctDNA plays a critical role in monitoring treatment response and detecting resistance. The emergence of the AR-V7 splice variant in ctDNA is a significant indicator of resistance to androgen receptor-targeted therapies. Liquid biopsies facilitate the timely identification of such resistance mechanisms, thereby guiding the selection of subsequent treatment lines [6].
The integration of liquid biopsies into clinical practice for monitoring tumor evolution is experiencing rapid advancement. Serial ctDNA analysis in various cancers, including pancreatic cancer, can track clonal evolution, identify driver mutations, and predict treatment response or relapse. This continuous molecular profiling empowers a more adaptive and individualized therapeutic approach [7].
Liquid biopsies provide a powerful tool for understanding the complex evolutionary landscape of brain tumors. By detecting tumor-derived mutations in cerebrospinal fluid (CSF) or plasma, it is possible to monitor treatment response and detect the emergence of resistance mechanisms in real-time. This non-invasive monitoring can significantly impact treatment strategies for challenging malignancies like gliomas [8].
The application of liquid biopsies in hematologic malignancies, such as leukemia and lymphoma, is rapidly expanding. Serial monitoring of ctDNA can assess treatment response, detect MRD, and identify the emergence of clonal evolution leading to relapse or resistance. This dynamic molecular profiling is crucial for the development of personalized treatment strategies in these diseases [9].
Finally, the utility of liquid biopsies extends to monitoring tumor evolution in pediatric cancers. Serial analysis of ctDNA can offer insights into tumor heterogeneity, response to therapy, and the development of resistance mutations. This non-invasive approach is particularly valuable in pediatric oncology, where minimizing invasive procedures is paramount for patient well-being [10].

Through the analysis of circulating tumor DNA (ctDNA) and other tumor-derived materials, these biopsies allow for real-time tracking of genetic alterations, resistance mechanisms, and minimal residual disease (MRD). This dynamic insight is crucial for personalizing treatment strategies, predicting treatment response, and detecting early relapse across various cancers, including non-small cell lung cancer, colorectal cancer, prostate cancer, and hematologic malignancies. Liquid biopsies aid in early detection of resistance mutations, inform treatment adjustments, and guide subsequent therapeutic choices. They are also vital for identifying residual disease and predicting relapse in solid tumors, and for understanding tumor heterogeneity and adaptation to therapy. In specific contexts like brain tumors and pediatric cancers, their non-invasive nature is particularly advantageous. The application of liquid biopsies in both solid and hematologic malignancies is rapidly expanding, leading to more adaptive and individualized therapeutic approaches and ultimately aiming to improve patient outcomes.
