From: Liquid biopsy in lung cancer: significance in diagnostics, prediction, and treatment monitoring
Clinical examination and diagnosis for lung cancer. Routine imaging examination for early examination and diagnosis of lung cancer includes X-ray, magnetic resonance imaging, and low-dose spiral computed tomography (CT). Vital approaches used to examine cancer tissue specimens include H&E staining, immunohistochemistry, and optical imaging modalities. Examination and diagnosis of peripheral blood with tumor antigens is routinely used in clinical examination. Liquid biopsy is emerging as a promising method for the identification of patients with a high risk of disease progression after curative surgery, as well as longitudinal monitoring for disease progression and therapy response
