Positron emission tomography/computerized tomography in lung cancer

Area of Science:

• Nuclear Medicine
• Oncology
• Radiology

Background:

• Lung cancer diagnosis and management require accurate staging and monitoring.
• Positron emission tomography (PET) offers functional imaging insights.
• 2-(18F)-flouro-2-deoxy-D-glucose (FDG) is a widely used PET tracer.

Purpose of the Study:

• To review the diverse clinical applications of FDG-PET in lung cancer.
• To highlight PET's role across the entire patient management pathway.
• To provide an evidence-based overview for clinicians.

Main Methods:

• Systematic literature review of studies utilizing FDG-PET in lung cancer.
• Analysis of diagnostic accuracy, staging capabilities, and prognostic value.
• Evaluation of PET in treatment response assessment and radiotherapy planning.

Main Results:

• FDG-PET demonstrates high accuracy in diagnosing primary lung cancer.
• PET is crucial for accurate staging, influencing treatment decisions.
• It effectively monitors treatment response, detects recurrence, and aids prognostication.

Conclusions:

• FDG-PET is an indispensable tool in modern lung cancer management.
• Its applications span diagnosis, staging, response assessment, and follow-up.
• PET imaging significantly improves patient outcomes through precise management.
