The Yield from Routine Chest X-Rays in Stage 3 Breast Cancer Patients

Context: Cancer of the breast is a common malignancy in Nigerian women and various imaging examinations, including the chest radiograph are routinely requested in all patients with this disease.Objective: The objective of this study was to determine the positive yield from routine chest radiographs in Nigerian patients with locally advanced stage 3 breast cancers but who had no clinical symptoms or signs of pulmonary or pleural metastatic disease. Methods: This descriptive retrospective study evaluated clinical records and chest radiographs of 61 female Nigerian patients with local stage 3 histologically diagnosed breast cancers, who presented at the radiotherapy unit of the University College hospital, Ibadan, over a 12-month period. Allabnormalities on the chest radiographs were documented.Results: The ages of the study group ranged from 25 to 67 years with a mean of 47years. Fortyseven (77%) of the patients had normal chest radiographs. Of the 14 abnormal radiographs, bilateral lung parenchymal metastases were seen in 4 cases one of whom also had bilateralpleural effusion. Other abnormal findings included hilar adenopathy, right lower lobe collapse, lymphagitis carcinomatosis and cardiomegaly.Conclusion: The authors conclude that a 23% detection rate from these screening chest radiographs is high and should be recommended as over 70% of Nigerian Patients with breast cancers present with advanced tumors
