The lung cancer is one of the commonest human kind cancer, the endobronchial variant is a relatively uncommon with a special presentation & diagnostic & therapeutic approach, the CXR is a cheap & widely available test the use too much in respiratory medicine ,Aim of the study To test the validity of CXR in detecting endobronchial lung cancer in comparison to chest CT with contrast & bronchoscopy &To correlate the CXR with the histological type & the staging of endobronchial lung cancer Patients & methods It is a cross sectional study include 37 patients with bronchogenic carcinoma , with written agreement to participate in the study & to do the procedure ,diagnosed by endobronchial bronchoscopical biopsy were included in the study from the period February 2018 to December 2019 most of them the bronchoscopy done as an outpatient procedure with local anaesthesia +/- light sedation , all the lesions were seen in the lumen during the bronchoscopy & the biopsies return back as bronchogenic cancer. All had CXR & CT which were collected & reviewed CXR were reviewed retrogradely by 1 radiologist & 1 pulmonologist with double blind pattern& classified as: Normal: no abnormality, Abnormal non CA: as fibrosis, COPD evidences, diffuse reticular shadow or Abnormal CA: mass, nodules, effusion, wide med., bony lesion. CTC were reviewed by 1 radiologist & 1 pulmonologist & classified as: CA or Non-CA. Smoker classified as Smoker: more than 100 cigarate / life or Non-smoker: < 100 cigarate / life
Histological Types: as NSCLC or SCLC. TNM scoring for staging: N: depending upon CT chest with contrast +/- EBUS TBNA. The results show that the CXR is not a good screening or diagnostic test for endobronchial lung cancer especially in early stages.
