Lung Cancer

We discussed a case of an elderly woman with extensive smoking history, who presented with chronic dry cough, chronic left upper arm pain, a remote episode of hemoptysis, and subacute dyspnea on exertion, which were all not improved despite a course of antibiotics, found to have a large R pulmonary mass due to Small Cell Lung Cancer.


  • Non-small cell lung cancer (80-90%)
    • Adenocarcinoma
    • Squamous cell carcinoma
    • Large cell carcinoma
    • Staging based on TNM cancer staging
  • Small cell lung cancer (10-20%)
    • One traditional way to stage is based on limited disease vs extensive disease.
      • Limited disease: tumor confined to the ipsilateral hemithorax and regional nodes, able to be confined to a single XRT port
      • Extensive disease: tumor beyond the boundaries of limited disease, including distant metastasis, malignant pleural or pericardial effusion, and contralateral lymphadenopathy
