Survival in gastric cancer is often limited by peritoneal carcinomatosis, which supposedly develops from serosal tumor infiltration or tumor cell spread during gastrectomy with lymphadenectomy. To eliminate peritoneal tumor cells, extensive intraperitoneal lavage (EIPL) has been suggested. Impressive results have been achieved in Japanese trials. In this trial, we assessed EIPL in Western patients. ⋯ In Western patients, free peritoneal tumor cells after gastrectomy with D2 lymphadenectomy for gastric cancer were detected only sporadically. Although based on few cases, the findings suggest that EIPL spreads tumor cells into the peritoneal cavity, thus being potentially harmful. Therefore, EIPL cannot be generally recommended.

Aneurysmal bone cyst (ABC) is a rare skeletal tumor usually treated with surgery/embolization. We hypothesized that owing to similarities with giant cell tumor of bone (GCTB), denosumab was active also in ABC. ⋯ Denosumab has substantial activity in ABCs, with favorable toxicity profile. We strongly support the use of surgery and/or embolization for the treatment of ABC, but denosumab could have a role as a therapeutic option in patients with uncontrollable, locally destructive, or recurrent disease.

Distinction between primary lung adenocarcinoma and metastatic adenocarcinoma from extrapulmonary origin in solitary pulmonary nodule (SPN) is crucial for cancer treatment. We investigated the predictive role of dual-time-point 18F-FDG PET/CT to distinguish primary and metastatic lung adenocarcinoma in SPN. ⋯ Dual-timepoint 18F-FDG PET/CT can be useful to distinguish primary and metastatic lung adenocarcinoma in SPN. Furthermore, it may also be useful to predict metastatic adenocarcinoma from colorectal origin.

One-lung ventilation (OLV) is an anesthesiological technique that is increasingly being used beyond thoracic surgery. This requires specific skills and knowledge about airway management, maintenance of gas exchange and prevention of acute lung injury. ⋯ Parameters validated for OLV titration still have not been found, but a multimodal approach based on low tidal volume, end-expiratory pressure application and alveolar recruitment maneuvers is considered the best way to ensure protective ventilation and reduce lung damage. The purpose of this review is to analyze all these factors using the latest scientific evidence and the opinions of the most influential authors.

Case Reports
IgG4-related disease in thymus. A very rare case of chronic fibrosis mimicking sarcoidosis.
IgG4-related disease (IgG4-RD) is a multi-organ immune-mediated chronic fibroinflammatory condition, with unclear certain etiology. It is morphologically characterized by storiform fibrosis, dense IgG4-positive lymphoplasmacytic infiltrate, and obliterative phlebitis. It was recognized as a systemic condition as recently as 2003. ⋯ We will describe, for the first time, the case of a 49-year-old man displaying an anterior mediastinic, hilar, and intramyocardial mass simulating a sarcoidosis, with a definitive diagnosis of IgG4-related thymic fibrosis extending to the mediastinum and the heart. At the histological examination, we found many features of IgG4-RD in the thymic tissue, such as diffused storiform fibrosis, dense lymphoplasmacytic infiltrate with abundant plasma cells IgG4 positive (ratio IgG/IgG4: 40%), obliterative phlebitis, eosinophilic infiltrate, and Castleman-like lymphoid follicles. We discussed the differential diagnosis and reviewed the literature and the other cases of IgG4-related diseases that had been diagnosed in our department.
