Clinical Biochemistry of Cancer

Clinical chemistry is a multidisciplinary field in medical sciences that concentrates on key qualitative and quantitative tests of critical analytes or markers in bodily fluids and tissues. It employs advanced analytical tools and techniques, along with specialized instruments, to carry out these tests. This interdisciplinary domain incorporates knowledge from toxicology, medicine, biology, chemistry, biomedical engineering, informatics, and other applied sciences, holding direct relevance to both plant and animal life. The hepatic system, responsible for metabolism and excretion, plays a key role in managing toxicants, substances, or chemicals that may cause harm through adverse effects or toxicity. Hepatotoxicants are chemicals or metabolites that can lead to liver injury, often resulting from biotransformation processes. Carcinogenicity, the ability to cause cancer, is a critical concern, with scientists assessing its risk through studies and regulatory bodies relying on data to guide cancer prevention and treatment. Toxicity denotes a substance’s harmful potential, affecting various organisms and cell types, leading to hepatotoxicity, nephrotoxicity, or cytotoxicity. Toxicity is dose dependent, varying with age, sex, and species. The Drug Toxicity Index (DTI) predicts clinical outcomes with insights beyond traditional dose–response. Tackling toxicity is crucial for ecosystem health and addressing environmental challenges.
