[Pathological-anatomical diagnosis according to the German lung cancer guideline 2018]

The German S3-guideline on prevention, diagnosis, therapy and follow-up of lung cancer, published in February 2018, expands on the 2010 guideline to include a total of 19 recommendations and statements regarding the "processing of lung resection specimens (tumor resection specimens)", "processing of lymph nodes", "histo-pathological typing and immunophenotype", "extent of tumor growth in resection specimens", "resection margins" or "R-classification", "grade of malignancy (grading)", "regression grading" as well as the "examination of molecular targets". The statements regarding the analysis of molecular targets result from the diagnostic requirements of the current targeted therapy of advanced lung cancer. At the same time, a pathological-anatomical diagnosis according to the current S3-guideline fulfills all corresponding requirements in certified lung cancer centers.
