"There is an ongoing debate about whether a tumour that crosses a fissure should be upstaged. The TNM staging system for lung cancer does not account for tumours crossing from one lobe of the lung into another. Evidence suggests that if a tumour can cross a complete fissure, it is likely more aggressive as it needs to traverse two layers of visceral pleura to do this. The PL grading system tries to account for this. The ninth edition of the TNM staging system for lung cancer is expected in 2024 3-6."

"Transfissural pulmonary diseases occur when a pathological process extends from one lobe via an interlobar fissure into an adjacent lobe 1. The finding is most commonly due to primary malignancy; however, some infections are known to do so."
