Background Risks associated with Video-Assisted Surgical Lung Biopsy (VASLB) for interstitial lung disease (ILD) with endotracheal intubation and mechanical ventilation are not nil. Awake Video-Assisted Surgical Lung Biopsy (Awake-VASLB) has been proposed as a method to obtain a precise diagnosis in several different thoracic diseases. Objectives To compare clinical outcomes of Awake-VASLB and Intubated-VASLB in patients with suspected ILDs. Methods From June 2016 to February 2020, all patients submitted to elective VASLB for suspected ILD were included. Differences in outcomes between Awake-VASLB and Intubated-VASLB were assessed through univariable, multivariable-adjusted, and a propensity score-matched (PS) analysis. Measurements and main results Awake-VASLB was performed in 66 out of 100 patients, while 34 underwent Intubated-VASLB. The Awake- VASLB resulted in a lower postoperative morbidity (OR 0.025; CI95% 0.001, 0.35; p=0.006), a less unexpected Intensive Care Unit (ICU) admission, a less need for rescue therapy for pain, a reduced surgical and anaesthesiologic time, a reduced chest drain duration, a lower postoperative length of stay. Conclusion Awake-VASLB in patients affected by ILD is feasible and seems safer than Intubated-VASLB.

Background: The heritage of occupational and environmental asbestos exposure in Piedmont, Italy, has resulted in an enduring diffuse pleural mesothelioma (DPM) epidemic. Our study aimed to investigate the accuracy of Pleural biopsy (PB) via thoracoscopy (or video-assisted thoracic surgery—VATS) and analyze the diagnostic path of patients who experienced an initial DPM misdiagnosis. Methods: Patients who underwent PB by VATS for suspected DPM from 2004 to 2013 were analyzed. The Registry of Malignant Mesothelioma (RMM) records were examined to cross-check incident cases and identify misdiagnosed DPM. The sensitivity and specificity of the initial PB assessment versus the final classification of cases by RMM were evaluated. Results: Data from 552 patients were analyzed, and DPM was diagnosed in 178 cases (32%). Sensitivity and specificity were 93% and 100%, respectively. The number of false-negative PBs was 14 (2%). Of those, 10 (71%) had an initial diagnosis of chronic pleuritis, 3 (28.5%) were initially classified as mesothelial proliferation, and 1 had reactive mesothelial proliferation. All of them reported a history of asbestos exposure, and the correct diagnosis was reached after a median of 160 days. One- and four-year survival rates were 52% and 10% in DPM PB-positive cases and 50% and 19% in false-negative cases. Conclusions: When a strong clinical suspicion after a negative PB remains, iterative biopsy attempts should be considered, especially if a history of asbestos exposure is reported. In high-volume centers, the DPM misdiagnosis rate remains low, and future advancements in diagnostic technologies could further increase the accuracy and efficacy of histologic diagnosis.

Objectives: Lung cancer is the leading cause of cancer-related deaths worldwide and mediastinal lymph node involvement is an important negative prognostic factor. Nevertheless, the involvement of a single mediastinal nodal zone has been reported to have favorable outcomes. This study aims to assess whether the prognosis of non-small-cell lung cancer (NSCLC) with single-zone lymph node involvement varies by the affected lymph node zone. Methods: We retrospectively analyzed patients affected by NSCLC with a single lymph node zone involvement who underwent anatomical resection. The prognosis of patients was statistically compared based on the different affected lymph node zones. Results: A total of 135 patients were enrolled. All patients underwent anatomical lung resection and systematic lymph node dissection. Lymph node involvement was observed in 50 cases (37%) for the upper zone, 36 cases (27%) for the aorto-pulmonary (AP) zone, 41 cases (30%) for the subcarinal zone and 8 cases (6%) for the lower zone. The median follow-up was 37 months [ranging from 1 to 115 months]. Cancer recurrence was reported in 64 cases (52%) during this period. The 2-year and 4-year overall survival (OS) were 69% and 49%, respectively. The 2-year and 4-year relapse-free survival (RFS) were 55% and 41%. The OS and RFS change relating to the different involved lymph node zones (p < 0.01). Lower zone involvement predicts worse prognosis, upper zone and subcarinal zone better outcomes, and the AP zone involvement intermediate survival. Conclusions: The location of the affected lymph nodes appears to be an important prognostic factor in patients with NSCLC, with significant impacts on both OS and RFS. It may play a key role in the disease progression and patient survival by providing more personalized therapy.
