摘　　要：原发性肺癌早期表现为孤立性肺结节（直径≤3cm），呈实性或磨玻璃状。随访评估结节的良恶性可实现肺癌的早期诊断，增加患者手术机会并显著延长患者生存期。体积倍增时间指体积增加一倍所需时间，反应观察对象的生长速度。一般，良性结节与恶性结节生长速度不同，故而研究肺结节的生长特点可辅助肺癌的鉴别诊断。Primary lung cancer are initially found as solitary pulmonary nodules （diameter ≤ 3 cm）, being solid or ground glass. Follow-up and evaluation of pulmonary nodules can assist early diagnosis of lung cancer, providing more chances for surgeries and therefore improving survival. Volume doubling time is the time taken for the volume to double, indicating how fast the objective grows. Generally, growth rates of benign and malignant nodules are different. Hence, learning about growth characteristics of pulmonary nodules is of great help in differential diagnosis of lung cancer.
