Non-Small Cell Lung Cancer (75% of lung cancer) is associated with involvement of the parietal pleura and or chest wall (soft tissue and/or bone) in 5-8% of patients. Invasion of the chest wall increases the T staging in the Tumor, Node, Mestasis (TNM) classification system of lung cancer to a T3 and is associated with decreased survival and more extensive operative procedures. The reported 5-year survival for patients with T2 tumors is 58% compared to 38% in patients with T3 lesions. The American college of Chest Physician has still not identified the best tool to assess chest wall invasion by lung cancer, CT-Scan being used by physicians for this assessment. In some studies, CT scan has been shown to have a sensitivity ranging from 42 % to 68 % in assessing chest wall invasion, and a specificity ranging from 66 % to 100 %.
