The objective of the study has been evaluated the pathological samples used for diagnosis of lung cancer and its histological type.Methods: A descriptive study of a random sample of 373 patients who were diagnosed with lung cancer in our hospital was performed. Demographic, clinical and pathological variables were recognized.Results: 77.21% (288) were male, with an average age of 66.74 years. 75.34% (288) were diagnosed by biopsy, obtained in 71.1% (200 samples) by pulmonologists (endobronchial or ultrasound-guided BAG). The most frequent cytological and histological diagnosis was non-small cell lung carcinoma and adenocarcinoma respectively. The diagnosis according to whether the sample obtained was cytological or histological is collected in Figures 1.The trend in the use of each type of sample over the years is represented in Figure 2.Conclusions: The shift to higher pathology samples is related to the increase in the therapeutic arsenal against lung cancer and a more personalized medicine.FootnotesCite this article as: European Respiratory Journal 2020; 56: Suppl. 64, 2918.This abstract was presented at the 2020 ERS International Congress, in session “Respiratory viruses in the "pre COVID-19" era”.This is an ERS International Congress abstract.
