Abstract

Lung cancer is a leading cause of cancer-death in most countries. Most patients are diagnosed with advanced stage hindering from radical resection or augmenting recurrence after curative therapy. Early detection and intervention of lung cancer may reduce disease specific mortality. For this purpose, several trials for lung cancer screening have been conducted but the results were consistently disappointing. Recently, the National Lung Screening Trial from USA, a nation-wide randomized controlled trial reported successful stories about lung cancer specific mortality reduction with low-dose CT screening for high risk participants who were current or former smokers, aged 55 to 74, compared with chest radiography screening. This is a brief review about lung cancer screening focusing up-front evidences and also unanswered questions regarding adequate screening strategies for future screening trials.
