Lung cancer staging now and in the future

Area of Science:

• Oncology
• Pulmonology
• Radiology
• Public Health

Background:

• Lung cancer management historically faced a fatalistic outlook.
• Recent advancements in diagnostics, imaging, and treatments offer optimism.
• Accurate staging is critical for determining treatment pathways and patient prognosis.

Purpose of the Study:

• To outline an optimal and resource-appropriate lung cancer staging algorithm for Asian healthcare settings.
• To emphasize the role of pulmonologists in a multidisciplinary approach.
• To advocate for uniform standards of care and tobacco control in Asia.

Main Methods:

• Contrast computed tomography (CT) of the chest and upper abdomen.
• Positron emission tomography/CT (PET/CT) for mediastinal and extrathoracic staging.
• Endosonography-guided needle sampling as an alternative to mediastinoscopy.
• Clinically indicated brain imaging.

Main Results:

• The proposed staging algorithm integrates advanced imaging and minimally invasive techniques.
• Adaptability of staging protocols is essential, considering diverse healthcare resources and economic factors in Asia.
• Pulmonologists are central to lung cancer diagnosis, staging, and management.

Conclusions:

• Optimal lung cancer staging requires a tailored, cost-effective approach considering regional resources.
• Collaboration among respiratory societies is needed to establish uniform care standards.
• Prioritizing tobacco control and cost-effective care delivery is paramount for improving lung cancer outcomes in Asia.
