Intrapulmonary metastases from bronchogenic carcinoma and their radiographic detection
Cancer Clinical Trials
|January 1, 1978
Summary
Autopsies show that 37.3% of patients with bronchogenic carcinoma develop pulmonary metastases. This lung cancer spread occurs early, often before diagnosis, and is detectable via X-ray.
Area of Science:
- Pulmonary Medicine
- Oncology
- Pathology
Background:
- Bronchogenic carcinoma is a leading cause of cancer death.
- Pulmonary metastases significantly impact patient prognosis and treatment strategies.
Purpose of the Study:
- To determine the incidence of pulmonary metastases in patients with bronchogenic carcinoma.
- To evaluate the timing of intrapulmonary spread relative to diagnosis.
- To assess the utility of radiographic examination in detecting these metastases.
Main Methods:
- Retrospective autopsy analysis of 102 patients with bronchogenic carcinoma over 11 years.
- Pathological review of questionable cases to confirm diagnoses.
- Radiographic assessment of intrapulmonary spread in conjunction with other pulmonary diseases.
Main Results:
- Autopsies revealed pulmonary metastases in 37.3% of patients.
- Intrapulmonary spread was evident early, with 34.7% of patients diagnosed within 1 month already showing additional foci.
- Radiographic identification of intrapulmonary spread was successful in over half of cases, despite concurrent lung disease.
Conclusions:
- Pulmonary metastases are a frequent complication of bronchogenic carcinoma.
- Early dissemination within the lungs is common.
- Radiographic examination is a valuable tool for detecting intrapulmonary spread, aiding clinical trial management.
