Gastric cancer is a significant global health concern, with high morbidity and mortality rates. Early detection and effective treatment strategies play a pivotal role in improving patient outcomes. The disease often develops silently in its early stages, with nonspecific symptoms, making early detection challenging. Several risk factors contribute to the development of gastric cancer, including a diet rich in smoked, pickled, or salty foods, chronic Helicobacter pylori infection, smoking, obesity, and family history [1]. Over the years, researchers have dedicated substantial efforts to identifying novel biomarkers that can aid in the diagnosis, prognosis, and personalized treatment of gastric cancer. Biomarkers for gastric cancer have emerged as essential tools in the early detection, prognosis, and personalized treatment of this deadly disease. These molecular indicators, found in various bodily fluids such as blood, tissue samples, or even breath, provide valuable insights into the presence and progression of gastric cancer. Some commonly studied biomarkers include Carcinoembryonic Antigen (CEA), Cancer Antigen 19-9 (CA 19-9) [2], and Human Epidermal Growth Factor Receptor 2 (HER2). Elevated levels of CEA and CA 19-9 have been associated with advanced stages of gastric cancer, aiding in disease staging and monitoring treatment response. HER2 overexpression, on the other hand, can guide targeted therapies, improving patient outcomes. The study provides insights into future perspectives on biomarker discovery and their potential applications in the management of this devastating disease.
Genetic biomarkers hold immense promise in gastric cancer research. We explore the role of specific gene mutations, chromosomal aberrations, and gene expression profiles that have been associated with gastric cancer development and progression. Moreover, we shed light on the exciting field of liquid biopsies, which utilize Circulating Tumor DNA (ctDNA) and Circulating Tumor Cells (CTCs) as non-invasive biomarkers for gastric cancer diagnosis and monitoring. Epigenetic modifications, such as DNA methylation and histone modifications have also shown great potential as gastric cancer biomarkers. We discuss their utility in identifying early-stage gastric cancer and predicting patient outcomes. Additionally, we examine the emerging field of non-coding RNAs, including microRNAs and long non-coding RNAs, which have demonstrated significant implications in gastric cancer biology and hold promise as diagnostic and prognostic markers. Proteomic and metabolomic approaches have unveiled a plethora of potential biomarkers for gastric cancer. We explore the use of mass spectrometry and other high-throughput techniques in identifying protein signatures associated with gastric cancer subtypes, tumor progression, and therapeutic responses [3,4].
In recent years, there has been significant progress in our understanding of the biology of gastric cancer. This has led to the development of new biomarkers that can be used to diagnose and stage the disease, as well as to predict patient response to treatment. One of the most promising new biomarkers is the protein PD-L1. PD-L1 is a checkpoint protein that helps tumor cells evade the immune system. Patients with high levels of PD-L1 in their tumors are more likely to respond to immunotherapy, a type of treatment that helps the immune system fight cancer. Another promising biomarker is the gene mutation BRAF. BRAF mutations are found in about 50% of gastric cancers. Patients with BRAF-mutant tumors are more likely to respond to targeted therapy, a type of treatment that specifically targets the BRAF gene. These are just a few of the new biomarkers that are being investigated in gastric cancer research. As we learn more about the biology of this disease, we will be able to develop even more effective diagnostic and treatment strategies. This will lead to improved outcomes for patients with gastric cancer [5].
The current research on novel biomarkers for gastric cancer has opened up new horizons in our understanding and management of this disease. These biomarkers offer great potential for early detection, accurate diagnosis, and personalized treatment strategies. They provide valuable insights into the molecular mechanisms underlying gastric cancer development and progression, as well as predicting patient outcomes and therapeutic responses. With advancements in molecular techniques and high-throughput technologies, the identification and validation of novel biomarkers continue to expand, bringing us closer to a future where gastric cancer can be detected and treated more effectively. The integration of these biomarkers into clinical practice holds the promise of improved patient outcomes, tailored therapies, and ultimately, a higher survival rate for those affected by this devastating disease. As we move forward, continued research and collaboration will be essential to fully harness the potential of novel biomarkers in gastric cancer, bringing us closer to a brighter future for patients and clinicians alike.
