The detection of serum-volatile organic compounds in the diagnostics of hepatocellular carcinoma using gas chromatography-ion mobility spectrometry.
Introduction: The third most common cause of cancer-related death worldwide is hepatocellular carcinoma (HCC), a malignant liver tumor that usually arises in patients with cirrhosis and chronic liver disease. New biomarkers are required for bidirectional validation of HCC in clinical practice because of its early asymptomatic stage, high mortality rate, and rapid tumor growth, as well as the high rate of false-positive results obtained for the commonly used serum marker alpha-fetoprotein (AFP).
Methods: This study used gas chromatography-ion mobility spectrometry (GC-IMS) combined with chemometrics to analyze the differences in volatile organic compounds (VOCs) in the serum of patients with and without hepatocellular carcinoma (HCC) in order to explore new biomarkers of HCC.
Results: The GC-IMS analysis detected 31 VOCs in serum, including 8 ketones, 11 aldehydes, 6 alcohols, 2 esters, and 1 furans, many of which differed in content between the controls and the patients with HCC.
Conclusions: The VOCs obtained from the use of these analytical devices can serve as a reference for developing low-cost equipment in the future. Considering its high efficiency and low cost, the detection of volatile organic compounds can be used as an auxiliary means of diagnosis or for mass screening of the population.
期刊介绍：
Frontiers in Chemistry is a high visiblity and quality journal, publishing rigorously peer-reviewed research across the chemical sciences. Field Chief Editor Steve Suib at the University of Connecticut is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to academics, industry leaders and the public worldwide.
Chemistry is a branch of science that is linked to all other main fields of research. The omnipresence of Chemistry is apparent in our everyday lives from the electronic devices that we all use to communicate, to foods we eat, to our health and well-being, to the different forms of energy that we use. While there are many subtopics and specialties of Chemistry, the fundamental link in all these areas is how atoms, ions, and molecules come together and come apart in what some have come to call the “dance of life”.
All specialty sections of Frontiers in Chemistry are open-access with the goal of publishing outstanding research publications, review articles, commentaries, and ideas about various aspects of Chemistry. The past forms of publication often have specific subdisciplines, most commonly of analytical, inorganic, organic and physical chemistries, but these days those lines and boxes are quite blurry and the silos of those disciplines appear to be eroding. Chemistry is important to both fundamental and applied areas of research and manufacturing, and indeed the outlines of academic versus industrial research are also often artificial. Collaborative research across all specialty areas of Chemistry is highly encouraged and supported as we move forward. These are exciting times and the field of Chemistry is an important and significant contributor to our collective knowledge.
