Despite recent advances in targeted therapy of non-small cell lung cancer (NSCLC), many patients do not benefit from these therapies. Inhibition of PD1/PDL1 is an interesting therapeutic target which restores the immune system against tumor cells. PD1 is located on lymphocytes and PDL1 on the antigen presenting cells. ⋯ Anti-PD1 and anti-PDL1 antibodies exposed to new adverse events including auto-immune diseases whose support is not codified. Questions about treatment duration and criteria evaluation are not resolved. These treatments pave the way for immunomodulation in NSCLC treatment.

Comparative Study
[Pneumonectomy for benign disease: indication and factors affecting the postoperative course].
Pneumonectomy for benign disease is rare but may generate more postoperative morbimortality than when performed for lung cancer. We questioned this assessment and retrospectively reviewed 1436 pneumonectomies and 54 completions of which 82 and 10 performed for benign disease (5.7% and 18.5%, respectively): left n=65 and right n=27. Indications were: post-tuberculosis destroyed lung (n=37), aspergilloma (n=18), bronchiectasis (n=19), infection (n=5), congenital malformations (n=5), inflammatory pseudotumor (n=3), trauma (n=2), post-radiation (n=2) and mucormycosis (n=1). ⋯ Considering patients with fungal infections versus others, mortality was 26.3% (n=5/19) and 2.7% (n=2/74), respectively (P=0.0028). Pneumonectomy for benign disease achieves cure with acceptable mortality and morbidity. However, presence of fungal infection should raise the attention for possibility of increased postoperative risks.

Lung hernias are rare and their pathogenesis is few described. They are defined as the protrusion of lung parenchyma through the chest wall: intercostal space, inter-costo-clavicular, supra-clavicular or diaphragmatic hiatus. Lung hernias are classically divided into congenital and acquired hernias. ⋯ Major risks are lung incarceration and necrosis but also ventilatory distress due to paradoxical respiration, in case of large defect. Treatment is first and foremost surgical but debated and should consider the localization, the size, the length of evolution and the possible infectious context. We report the case of a right basi-thoracic lung hernia induced by a cough fit, in a patient with chronic bronchitis.
