Target Therapy in Lung Cancer.

Area of Science:

• Pulmonology
• Oncology
• Pathology

Background:

• Lung cancer exhibits significant heterogeneity with over 50 histological variants.
• Accurate classification is crucial for effective patient management and targeted therapy.

Purpose of the Study:

• To introduce a new international multidisciplinary classification for lung cancer.
• To address diagnostic challenges and strategic management, especially for molecular testing in small specimens.
• To incorporate advances in lung cancer treatment and personalized therapy.

Main Methods:

• Development of an international multidisciplinary classification by IASLC, ATS, and ERS.
• Revision and enhancement of the existing World Health Organization (WHO) lung cancer classification system.

Main Results:

• The new classification increases histological heterogeneity and refines the WHO system.
• It facilitates molecular testing in small biopsy and cytology specimens.
• It supports the era of personalized therapy for lung cancer.

Conclusions:

• The revised lung cancer classification is essential for the personalized therapy era.
• It improves diagnostic accuracy and strategic management for lung adenocarcinoma patients.
• This advancement enables tailored treatment approaches based on individual patient profiles.
