Conservative Treatment in Tracheobronchial Injuries—An Institutional Report

Tracheobronchial injuries are rare but potentially high-impact events with significant morbidity and mortality. Common etiologies include blunt or penetrating trauma, often combined with various complex injuries, while iatrogenic injury usually occurs during operation, intubation, or bronchoscopy. An early and accurate diagnosis and a multidisciplinary approach in a center experienced in treating airway lesions are essential to obtain favorable results. For a long time, surgery has been considered the treatment of choice for post-traumatic airway lesions. However, recent reports have shown a paradigm shift in the management of tracheal injury towards a conservative approach, especially in treating iatrogenic lesions. In our experience of 11 consecutive patients, although there are still definitive indications for surgery, we demonstrated the effectiveness of conservative treatment in patients with mixed varieties of tracheal injury by etiology, extension, and complications

Clinical score for colorectal cancer patients with lung-limited metastases undergoing surgical resection: Meta-Lung Score

Background: Radical resection of isolated lung metastases (LM) from colorectal cancer (CRC) is debated. Like Fong's criteria in liver metastases, our study was meant to assign a clinical prognostic score in patients with LM from CRC, aiming for better surgery selection. Methods: We retrospectively analyzed data from 260 CRC patients who underwent curative LM resection from December 2002 to January 2022, verifying the impact of different clinicopathological features on the overall survival (OS).Results: At the univariate analysis: higher baseline CEA levels (p = 0.0001), disease-free survival less than or equal to 12 months (m) (p = 0.0043), LM size larger than 2 cm (p = 0.0187), multiple resectable nodules (p = 0.0083), and positive nodal status of the primary tumor (p = 0.0011) were associated with worse prognosis. In a Cox regression model, these characteristics retained their independent role for OS (p < 0.0001) and were chosen as criteria to be assigned one point each for clinical risk score. The 5-year survival rate in patients with 0 points was 88%, while no patients with a 5-point score survived at 2 years. Based on the 0-1 vs. 2-5 score range, we obtained a significant difference in median OS: not reached vs. 40.8 months (95 %CI 36 to 87.5), respectively (p < 0.0001) stratifying patients into good and poor prognosis. The prognostic role of the score was also confirmed in terms of median RFS: not reached in 0-1 scored patients vs. 30.5 months (95 %CI 19.4 to 42) in patients with 2-5 scores (p = 0.0006).Conclusions: When LM from CRC is resectable, the Meta-Lung Score provides valuable prognostic information. Indeed, while upfront surgery should be considered in patients with scores of 0 to 1, it should be cautiously suggested in patients with scores of 2 to 5, for whom a prognosis comparison between preventive surgery and other treatments should be investigated in prospective randomized clinical trials
