Background: Tumors of the chest wall have a large spectrum of well-assessed indications for resection. However, whether a reconstruction is required or not is not always clear. Complications after chest wall resection and reconstruction (CWRR) are described in literature and potentially severe. There is no evidence of how non-reconstructive management may influence the post-operative complication rate. Methods: A total of 71 patients underwent thoracic demolition for tumors between April 2000 and October 2016. The patients were divided into two groups based on pathological findings: group 1: primary chest wall tumors; group 2: non-small cell lung cancer (NSCLC) invading the thoracic wall. They were then retrospectively analyzed by means of following criteria: TNM staging, histology, infiltration depth, 5-year survival, overall survival (OS), disease-free survival (DFS), relapse rate, R-0 resection, number of resected ribs, site of surgical resection and post-operative respiratory complications, flail chest, chronic pain, deformity of the chest wall and cosmetic results. Results: Five-year survival, OS, DFS and risk of relapse showed a significant correlation with the presence of free surgical margins in both groups. In group 2, another parameter which correlated to survival, risk of relapse and DFS was lymph-nodal status. Moreover, the risk of post-operative respiratory complications was directly correlated with non-reconstruction after demolition of the chest wall in certain topographical sites. Conclusions: free surgical margins are the main oncological prognostic factor in these patients. In patients who underwent resection of two or more ribs in a critical area, reconstruction of the bony thorax can significantly reduce the post-operative respiratory complication rate.

Ovarian cancer is the most lethal gynaecologic malignancy. It usually spreads out of the abdomen involving thoraco-abdominal organs and serosal surface. This disease is poorly curable and surgery, at early stage, is supposed to achieve the best survival outcome. In systemic dissemination, chemiotherapy is indicated, sometimes with neoadjuvant aim. The most common clinical expressions of advanced ovarian carcinoma are multiple adenopathy, neoplastic pleuritis, peritoneal seeding and distant metastasis, mainly hepatic and pulmonary. Isolated adenopathy of the mediastinum is rare and isolated bilateral have never been described before. We report two cases of isolated bilateral cardiophrenic angle lymphnode metastasis from ovarian carcinoma, without peritoneal and pleural involvement. Both patients were successfully resected through minimally invasive thoracic surgery. About the role of surgery, few data are available but survival seems to be longer after resection thus, more investigation is required to make the indication to surgery more appropriate in advanced cases.

Aim of this study is to analyze outcome and the decision making process to approach airway invasion by thyroid tumors. Retrospective study of 30 years experience in thyroid surgery for cancer invading airway. Clinical records, surgical and pathology reports have been analyzed to assess which principles and procedural details are significant to facilitate efficient diagnosis, staging and treatment. Medical therapy was not evaluated. Out of a consecutive series of 2165 thyroid cancer patients, T4a cancers are 303 (14%). Airway invasion was found in 141 (6.5%) cases. Well-differentiated pattern was determined in 110 (78%) while other histology was reported in 31 (22%). Airway-related symptoms have been recorded in 111 (78%) patients. Flexible bronchoscopy was performed in all patients. Rapidly evolving disease or non-resectable airway was found in 105 (74.5%) cases. Permanent tracheotomy was performed in 43 (30.5%) cases, airway lumen restoration with or without stenting in 39 (27.7%), laryngectomy in 8 (5.7%), segmental airway resection and reconstruction in 28 (19.9%). Perioperative mortality was recorded after palliative treatment only. In resected patients, completely radical surgery was not always achievable. All patients with positive margin after resection underwent adjuvant treatment and showed comparable survival to radical surgery patients after 5 years. Tumor relapse occurred in 8 (28.6%) cases (distant or locoregional). Patients with unresectable disease require treatment for symptoms relief but survival is poor. Although some patients are currently referred with a severely advanced disease, the indication for tracheotomy, salvage procedures or supportive care has decreased over time. Resection is feasible for differentiated tumors with an overall good outcome.

3D-printing technologies can assist the surgical planning and prosthesis engineering for the management of extended chest wall resection. Different types of prosthesis have been utilized over time, but some concerns remain about their impact on the respiratory function. Here we present a new kind of 3D-printed titanium prosthesis designed to be either strong and flexible. The prosthesis was created on a 1:1 3D-printed anatomic replica of the chest, used to delineate surgical margins and to define the reconstructive requirements.

Left main bronchus resection and reconstruction (LMBRR) is a complex surgical procedure indicated for management of inflammatory, benign and low grade malignant lesions. Its application provides maximal parenchymal sparing.
