Abstract
Lung cancer presents with chest wall invasion in 5-8% of patients, which imparts some treatment challenges. Surgical resection is currently the standard of care, and there are some controversies regarding the best approach. Published series and case reports confirm the safety and feasibility of video-assisted thoracoscopic surgery (VATS) in highly complex surgical cases including lobectomy with chest wall resection of locally advanced lung cancer. In this article, we present the clinical indications of locally advanced lung cancer that infiltrates the chest wall, the modalities for and importance of accurately staging lung cancers with chest wall invasion, and the technical aspects of accomplishing a safe and oncologically sound extended resection through VATS.

Abstract
The aim of this study was to analyze chest wall invasion, the indication and multidisciplinary nature of treatment, the methods used for parietal reconstruction and the technical problems posed by this procedure in patients with lung cancer and chest wall invasion. Chest wall invasion from adjacent malignancies affects 5% of patients with a bronchogenic carcinoma. Preoperative determination of parietal invasion aids the planning of an appropriate therapeutic approach. Positron emission tomography combined with computed tomography (PET/CT) improves the study of T-factor and metastatic nodal involvement and distant metastases. As a rule, surgical treatment should attempt complete tumoral resection: lobectomy, resection of the parietal pleura and/or of the chest wall--ensuring tumor-free margins--and hilar and mediastinal lymphadenectomy. We also analyzed the distinct prognostic factors for survival, as well as the indication for induction or adjuvant therapy. Chest wall reconstruction involves recreating the most anatomical and physiological conditions possible in the chest cavity and surrounding muscles. The ideal reconstruction would achieve adequate parietal stability and coverage to preserve functionality, with the cosmetic result being an important, but secondary, consideration. Many materials are available for reconstruction and the choice of material should be individualized in each patient. A multidisciplinary team able to plan and perform the resection and subsequent reconstruction, oversee postoperative management and treat complications early is essential.

Abstract
Surgical resection is the accepted standard of care for patients with non-small cell lung cancer (NSCLC). Several imaging modalities play central roles in the detection and staging of the disease. The aim of this review is to evaluate the utility of computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET) and PET/CT for NSCLC staging. Radiographic staging refers to the use of CT as a non-invasive diagnostic technique. However, while the vast majority of patients undergo only CT, CT is a notoriously inaccurate means of tumor and nodal staging in many situations. PET/CT clearly improves the staging, particularly nodal staging, compared to CT or PET alone. In addition, as a result of the increased soft-tissue contrast, MRI is superior to CT for distinguishing between tissue characteristics. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), which is a minimally invasive technique, also has pathological diagnostic potential. Extensive research and the resultant improvements in the understanding of genetics, histology, molecular biology and oncology are transforming our understanding of lung cancer, and it is clear that imaging modalities such as CT, MRI, PET and PET/CT will have an important role in its preoperative management. However, thoracic surgeons should also be aware of the limitations of these techniques.

Abstract
PURPOSE To develop a simple noninvasive technique for evaluating pleural invasion by using routine preoperative computed tomography (CT). MATERIALS AND METHODS The institutional review board approved this retrospective study, and written informed consent was obtained for performing the initial and follow-up CT studies. Preoperative CT findings (169 patients with possible pleural invasion) and pathologic diagnoses after surgical resection were evaluated. The length of the interface between the primary tumor and neighboring structures (arch distance) and the maximum tumor diameter were measured on CT images, after which arch distance-to-maximum tumor diameter ratios were calculated. Receiver operating characteristic (ROC) curves were used to analyze the ratios. RESULTS Median arch distance-to-maximum tumor diameter ratios for pleural invasion categories (pl1, pl2, pl3) assessed by using the Union Internationale Contre le Cancer TNM staging system were as follows: pl1, 0.206 (25th-75th percentile, 0-0.486); pl2, 0.638 (25th-75th percentile, 0.385-0.830); and pl3, 1.092 (25th-75th percentile, 1.045-1.214) (P < .001 between groups). On the basis of the ROC curves, the cut-off value for invasion was an arch distance-to-maximum tumor diameter ratio of 0.9. When the ratio was greater than 0.9, the sensitivity and specificity for thoracic invasion and area under the ROC curve were 89.7%, 96.0%, and 0.976, respectively, which represents an improvement over values obtained by using conventional criteria (radiologists A and B: 46.7% and 74.2% and 91.3% and 84.8%, respectively). CONCLUSION When diagnosing T3 or T4 lung cancer based on arch distance-to-maximum tumor diameter ratios, a higher performance level was achieved than that with use of conventional criteria. Measurement of the ratios is a simple noninvasive technique for evaluating pleural invasion at CT.

Abstract
UNLABELLED Multimodal management of lung cancer extending to chest wall and type of surgical procedure to be performed are still debated. The aim of this retrospective analysis was to analyze the predictive factors of long-term survival after surgery, focusing on depth of infiltration, type of surgical intervention and possible role of preoperative therapies, comparing survival of these patients with that of a group of patients affected by a Pancoast tumour and surgical treated in the same period. MATERIALS AND METHODS We reviewed records of 83 consecutive patients with NSCLC in stage T3 (owing to direct extension to chest wall), who underwent surgical resection in our Thoracic Surgery Unit between January 1994 and December 2003. Patients were classified in two groups: pancoast tumours (PT) or chest wall extending tumours (CW): survival and prognostic factors of each category were analyzed. RESULTS In the CW group we had 68 patients: 45 were in stage IIB (pT3N0), 23 in stage IIIA (pT3-N1-2). Histology revealed adenocarcinoma in 23 cases, squamous cell carcinoma in 34, large cells anaplastic carcinoma in 8, adenosquamous carcinoma in 3. An involvement of chest wall tissues beyond the endothoracic fascia was found in 21 patients, while in the remaining 47 the invasion of chest wall tissues was confined to the parietal pleura. An extrapleural dissection was performed in 48 patients while combined pulmonary and chest wall en bloc resection was required in 20 patients. Resection was incomplete in three cases. In the PT group we had 15 patients: 11 were in stage IIB and 4 in stage IIIA. Histological type was adenocarcinoma in 10 cases, squamous cell carcinoma in 4 and adenosquamous carcinoma in 1. A univariate analysis performed in the CW group showed that survival was significantly affected by nodal status, stage, extension of chest wall invasion, type of lung resection and residual disease. In a multivariate analysis we found that nodal status, completeness of resection and extension of chest wall involvement maintained a significant prognostic value. There was no difference between the survival curve of CW and PT group: considering the two subset of CW patients, on the basis of depth of infiltration, survival of PT patients was significantly better than that of CW patients with involvement of muscular tissues and ribs (p=0.02). CONCLUSION Nodal status, radical resection and depth of chest wall infiltration are the main predictive factors affecting long-term survival, while surgical procedure does not impact on it if margins of resection are free from disease. The better survival observed in PT patients let us to hypothesize that an induction chemo-radiation therapy, as routinely administered to PT patients, could have a potential benefit in survival of patients with CW tumour extending beyond parietal pleura.

Abstract
Computed tomography (CT) is still the cornerstone of imaging studies in the preoperative staging and post- therapeutic evaluation of lung cancer. The most recent developments in multidetector technology have dramatically improved the temporal and spatial resolution of CT. In the mean time, magnetic resonance imaging (MRI) has not become a routine examination in lung imaging and is today only used as a problem-solving tool in patients in whom CT remains equivocal. This article will describe the current tools developed in the multidetector CT era for evaluating the lung, and state-of-the-art MR examination of the chest. Then, the role of CT and MRI in nodule detection, the distinction between benign and malignant nodules, and the benefit of CT and MRI in the staging and post-therapeutic evaluation of lung cancer will be covered.

Abstract
PURPOSE Most early publications on integrated positron emission tomography/computed tomography (PET/CT) devices have reported the new scanner generation to be superior to conventional PET. However, few of these studies have analysed the situation where, in addition to PET, a current CT scan is available for side-by-side viewing. This fact is important, because combined PET/CT or a software-based fusion of the two modalities may improve diagnosis only in cases where side-by-side reading of PET and CT data does not lead to a definitive diagnosis. The aim of this study was to analyse which patients will profit from integrated PET/CT in terms of lesion characterization. METHODS A total of 328 consecutively admitted patients referred for PET in whom a current CT scan was available were included in the study. The localization of all pathological PET lesions, as well as possible infiltration of adjacent anatomical structures, was assessed. RESULTS Of 467 pathological lesions, 94.0% were correctly assessed with respect to localization and infiltration by either conventional PET alone (51.6%) or combined reading of PET and the already existing CT scans (42.4%). Hence, in only 6.0% of all lesions, affecting 6.7% of all patients, could evaluation have profited from integrated PET/CT. CONCLUSION We conclude that side-by-side viewing of PET and CT scans is essential, as in 42.4% of all cases, combined viewing was important for a correct diagnosis in our series. In up to 6.7% of patients, integrated PET/CT might have given additional information, so that in nearly 50% of patients some form of combined viewing of PET and CT data is needed for accurate lesion characterization.

Abstract
STUDY OBJECTIVES The treatment of patients with non-small cell lung cancer (NSCLC) that is invading the chest wall is still debated. We aim to illustrate the improvements in treatment results that have occurred over last decade. DESIGN Retrospective analysis of our experience and an overview of the literature. SETTING Department of Surgery, San Giuseppe Hospital, University of Milan. PATIENTS From January 1970 to December 1999, of 2,738 patients with NSCLC, we operated on 146 patients (5.4%) with chest wall invasion by NSCLC. Superior sulcus tumors and tumors invading the diaphragm or mediastinum were excluded. We reclassified all cases according to the current TNM classification. RESULTS We registered one postoperative death (0.69%) and five major complications (3.4%). From 1970 to 1979, of 32 patients, 10 underwent an exploratory thoracotomy (ET) and 22 underwent a radical resection (stage IIB disease, 17 patients; stage IIIA disease, 5 patients). The 5-year survival rate was 22.7% (25% for stage IIB disease). From 1980 to 1989, of 67 patients, 11 underwent an ET and 56 underwent a radical resection (stage IIB disease, 34 patients; stage IIIA disease, 12 patients; stage IIIB disease, 5 patients; and stage IV disease, 5 patients). The survival rate following radical resection was 14.1%, ranging between 23.5% for patients with stage IIB disease and 0% (3 years, 14%) for those with stage IIIA disease. From 1990 to 1999, of 47 patients, 2 underwent an ET, 2 underwent an exploratory thoracoscopy, and 43 underwent a radical resection (stage IIB disease, 23 patients; stage IIIA disease, 20 patients). The survival rate was 42.7% (stage IIB disease, 78.5%; stage IIIA disease, 7.2%). CONCLUSIONS Considering the low morbidity, mortality, and significant improvement in survival during the last decade, we advocate the performance of radical en bloc resection for the treatment of chest wall invasive NSCLC.
