[Pathologic analysis of 302 primary bronchogenic adenocarcinomas]

Area of Science:

• Pulmonary pathology
• Oncology
• Surgical pathology

Context:

• Bronchogenic adenocarcinomas represent a significant portion of lung cancers.
• Understanding the pathomorphology and subtypes is crucial for diagnosis and treatment.
• This study reviews a large cohort of resected lung adenocarcinomas.

Purpose:

• To analyze the pathomorphology of primary bronchogenic adenocarcinomas.
• To classify subtypes based on WHO histologic criteria.
• To evaluate survival rates and prognostic factors.

Summary:

• A retrospective analysis of 302 lung adenocarcinomas (23.5% of total lung cancers) from 1957-1984.
• Peripheral adenocarcinomas (82.4%) were more common than central (15.9%) or disseminated (1.7%) types.
• WHO subtypes included acinar, papillary, bronchiolo-alveolar, and solid carcinoma with mucus.
• Five-year survival was 19.6%, with better outcomes for peripheral types and no metastasis.

Impact:

• Provides insights into the distribution and characteristics of lung adenocarcinoma subtypes.
• Highlights the prognostic significance of tumor location and metastasis.
• Contributes to the understanding of lung cancer pathology and patient outcomes.
