Abstract
This document reviews the evidence supporting different imaging modalities and techniques used to evaluate patients with a history of lung cancer. It focuses on the imaging evaluation of patients treated for stage I-III non-small-cell lung cancer and small-cell lung cancer, whether using individual modalities or combinations. Guidelines for both routine surveillance of stage I-III lung cancer and for the evaluation of suspected recurrence or disease progression are provided. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.
