Background:
The frequency and grade of pulmonary complications after radiotherapy for breast cancer are still debated. This study evaluated changes in pulmonary function tests (PFTs) after radiotherapy in women with breast cancer.
Patients And Methods:
Thirty-five consecutive eligible women with breast cancer underwent pulmonary function testing before and 3 months after adjuvant radiotherapy. Twenty-one of them also received chemotherapy.
Results:
A significant decrease of forced vital capacity, forced expiratory volume in one second and carbon monoxide diffusing capacity was observed in the women treated with locoregional adjuvant radiotherapy and chemotherapy, whereas no decrease of the above parameters was evidenced in women treated exclusively with local adjuvant radiotherapy.
Conclusion:
Local adjuvant radiotherapy is not associated with any reduction in lung function parameters, however, locoregional adjuvant radiotherapy combined with chemotherapy shows a significant reduction in PFTs 3 months after radiotherapy completion.

01:25Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...
01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
01:30Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
