Overview
Lung biopsy is the gold standard test for diagnosis of lung mass. However, in order to determine the extent of lung mass and to derive therapy other tests such as CT scan, sputum cytology and PET scan are also necessary. According to the American Joint Committee on Cancer (AJCC) staging system, there are 4 stages of malignant lung mass, based on 3 factors: tumor size, lymph node invasion, and metastasis. Each stage is assigned a letter and a number that designate T for tumor size, N for node invasion, and M for metastasis.
Diagnostic Study of Choice
Study of Choice
Lung biopsy is the gold standard test for the diagnosis of lung mass. However, in order to determine the extent of lung mass and to derive therapy other tests are also necessary.[1][2][3]
- A multidisciplinary approach is required to correctly identify the sub-type of lung mass and its staging.
- In general, diagnosis of lung mass is supplemented by the presence of clinical, radiological and pathological evidence.
- Mode of biopsy also depends upon the age and condition of patient. These include:
- Ultrasound guided bronchial washings/brushings and aspiration.
- Bronchoscopy or CT-guided biopsy.
- Unreachable lesions are evaluated with video-assisted thoracoscopic surgery.
- Frozen sections in case of patients already undergoing surgery for a secondary condition.
