Multidisciplinary management of lung cancer with PET-CT, tissue biopsy, staging, and molecular testing in patients with suspicious pulmonary nodules or masses.
Indication
- Cough lasting longer than three weeks, blood-streaked sputum, or hoarseness
- Unexplained weight loss, loss of appetite, and persistent fatigue
- Suspicious nodules or masses detected on chest X-ray or CT
- Long-term smoking history or occupational exposure to asbestos or radon
- Family history of lung cancer and eligibility for a lung cancer screening program
- Recurrent pneumonia, pleural effusion, or unexplained thrombotic events
Preparation
- Collection of previous chest X-rays, CT/PET images, and pathology reports
- Detailed documentation of smoking history, occupational exposure, and family history
- Adjustment of blood thinners with physician approval before biopsy
- Fasting for at least 6 hours before bronchoscopy or needle biopsy
- Updated reports on accompanying cardiac and renal conditions
How it's performed
- Detailed history-taking and physical examination to assess risk factors
- Staging imaging with thoracic CT, PET-CT, and brain MRI when needed
- Bronchoscopy, EBUS, or CT-guided transthoracic needle biopsy depending on lesion location
- Histopathologic evaluation; differentiation between small cell and non-small cell types
- Molecular and immunohistochemical testing including EGFR, ALK, ROS1, KRAS, and PD-L1
- Treatment planning at the multidisciplinary tumor board for surgery, chemotherapy, radiotherapy, targeted therapy, or immunotherapy
Post-procedure
- Imaging and clinical evaluation every 2-3 months during treatment
- Follow-up every 3-6 months in the first 2 years after treatment, then every 6-12 months
- Smoking cessation support and pulmonary rehabilitation programs
- Recommendation of pneumonia and influenza vaccines
- Surveillance for secondary cancers and concurrent cardiovascular disease
Risks
- Pneumothorax, bleeding, or infection related to biopsy procedures
- Systemic side effects of chemotherapy, targeted therapy, and immunotherapy
- Radiotherapy-related pneumonitis, esophagitis, and skin reactions
- Respiratory failure, pleural effusion, and metastatic disease during the course of illness
- Fatigue, depression, and reduced quality of life associated with treatment
FAQ
Is lung cancer always caused by smoking?
Smoking is a major risk factor; however, lung cancer can also occur in people who have never smoked due to radon, asbestos, air pollution, or genetic factors.
If a nodule is found, does it definitely mean cancer?
Most nodules may be benign. Follow-up or biopsy is planned based on size, appearance, and risk factors; a definitive diagnosis is made only with tissue examination.
Should I have a screening test?
Low-dose lung CT screening may be recommended for individuals who meet specific age and smoking criteria; your physician will determine eligibility.
Can I continue working during treatment?
It depends on the type of treatment, side effects, and overall condition; some patients continue with adjusted schedules while others may need temporary leave during treatment.
