Non–Small-Cell Lung Cancer Diagnosis and Staging Evaluation

Physical examination Chest x-ray Bronchoscopy Fine-needle aspiration CT scan PET scan Laboratory analysis Mediastinoscopy

Purpose

Identify signs Determine position, size, number of tumors Determine location of tumor, obtain biopsy Cytology Identify chest-wall invasion, mediastinal lymphadenopathy, distant metastases Mediastinal, lymph-node and extrathoracic staging Detect changes in hormone production, and hematologic manifestations of lung cancer Visualize and sample mediastinal lymph nodes 1

Overview of NSCLC Treatment Options Early-stage tumor

  Surgery Radiation for inoperable patients

Locally advanced tumor

 Surgery   Chemoradiation Surgery + chemoradiation

Advanced tumor

 Chemotherapy   Targeted therapy Chemotherapy + targeted therapy NCCN Clinical Practice Guidelines in Oncology. NSCLC. V.I.2007. Available at: http://www.nccn.org/professionals/physician_gls/pdf/nscl.pdf. Accessed May 18, 2007.

Conclusion

In a population-based cohort, PORT use is associated with an increase in survival in patients with N2 nodal disease but not in patients with N1 and N0 nodal disease.
