ABSTRACT
Introduction: Lung cancer (LC) emerges as a principle cause of death among smokers and is also one of the most lethal forms of cancer in nonsmokers. LC is mainly classified as non-small cell lung cancer (NSCLC), small cell LC, and lung carcinoid tumor. NSCLC is the most prevalent form of LC and its early stage diagnosis is essential to reduce mortality rate of patients and provide specific therapy. The field of LC diagnostics witnessed a gradual escalation with advancement in technology.
Areas covered: This comprehensive review focuses on classification of LC and advanced diagnostics for LC detection like biosensors, biomarkers, nanotechnology-based diagnostics, wearable devices, mobile health, artificial intelligence (AI), aptamers, and molecularly imprinted polymers (MIPs).
Expert opinion: Liquid biopsy and breath analysis developments are the most promising and advanced technologies for the detection of biomarkers associated with LC. Wearable devices and AI are two niche areas that require development and standardization for commercialization. The upcoming technology based on nanosystems includes robots, fibers, and particles for sensitive detection of LC. In the near future, nanotechnology-based theranostics, aptamers, and MIPs will emerge in early-stage diagnosis of LC.
