Failure profile following surgical resection of carcinoma of the lung - abstract

Most patients with carcinoma of the lung are not amenable to surgical resection. One thousand and eighty-eight patients were screened and 186 were found to fulfil the surgical requirement for treatment. Surgical resection was undertaken only in patients in whom disease was thought to be limited to the lung. Following Staging Procedures, only 17 percent of this series were treated surgically. Long-term survival showed a direct relationship to tumor size and mode of spread (AU)

Bronchogenic carcinoma - a radiologic tragedy - abstract

This study attempted to establish the radiological appearances of bronchogenic carcinoma in Jamaica and to compare these with some North American patterns. The presenting chest X-Rays in sixty patients with histologically proven bronchogenic carcinoma were reviewed and the radiological patterns identified. Eighteen (18) cases presented as solitary parenchymal masses with 8 associated with hilar adenopathy and 3 with pleural effusions. Five cases had a peripheral mass with adjacent rib destruction - 4 being apical tumours, the histological types being anaplastic, squamous cell and undifferentiated carcinoma. Eighteen (18) cases presented as a hilar mass and 8 were associated with atelectasis. Four cases presented with complete lobar or lung collapse, 7 as massive pleural effusions, 3 as multiple pulmonary nodules, 2 as cavitating masses and one each as diffuse infiltrate, atelectasis with hilar calcification and superior mediastinal widening. Thirty-two (32) had measurable masses. Of the nineteen measurable peripheral masses, there were less than 3 cm in diameter and sixteen measured between 5 and 12 cm in diameter. Comparable results from the Lehey Clinic Series revealed twenty-five peripheral masses measuring less than 3 cms in diameter and sixteen greater than 3 cms in diameter. The large size of the mass lesions and evidence of spread of malignancy at the time of presentation indicate a high incidence of advanced disease when compared with the Lehey Clinic pattern and the results of the Philadelphia Pulmonary Neoplasm Research Project. A public education campaign and more regular use of routine chest X-Rays in the age group at risk are necessary for prevention and early diagnosis (AU)

Radiological presentation of bronchogenic carcinoma in Jamaica

Bronchogenic carcinoma is not an uncommon disease in Jamaica and usually presents radiologically as a hilar mass, collapse and/or consolidation, a peripheral shadow opacity of one hemi-thorax. Comparison of the radiological appearances with those of other series shows that the main difference is the presence of those cases with complete opacity of one hemi-thorax. This radiological appearance indicates an advanced stage of the disease due to the fact that patients seek medical advice at a late stage. The relative frequency of peripheral and central cases in the Jamaican series is similar to that found in the United States of America and the United Kingdom and France, suggesting that on the basis of the radiological appearance, bronchogenic carcinoma in Jamaica is similar to the disease in other parts of the world (AU)

Radiological appearance and diagnosis of bronchogenic carcinoma in Jamaica

Review of the radiological presentation of 70 cases of bronchogenic carcinoma seen at the University Hospital from January 1960 to December 1966. On the basis of their radiological appearances, the bronchogenic carcinomas can be classified into the following types: 1. Englarge hilum 2. Collapse or consolidation 3. Pleural effusion 4. Complete opacity of one side of chest 5. Large circumscribed mass 6. Pancoast type of tumour 7. Small circumscribed mass (coin lesion) 8. Occult carcinoma. Radiological appearance of chest being normal. Examples of each type will be shown with comments. The incidence of the different types in the present series will be compared with the incidence of different types in series from other countries. The value of special radiological procedures in the establishment of the diagnosis of bronchogenic. 1. Tomography. This technique has two main applications. (a) To demonstrate to tracheal bi-furcation and lumen of the main bronchi. This application can be regarded as an extension of bronchoscopy and can be used as a complementary investigation to this surgical technique. The main application is in the investigation of: i. The enlarged hilum ii. Collapse of a lobe iii. Complete opacity of a hemi-thorax. Similar information can be given by bronchography and sometimes by a penetrated view of the chest. (b) To demonstrate the edge of a lesion. This is of value in revealing the nature of the edge of the shadow of circumscribed masses, either small or large. (c) To reveal the presence of cavitation or calcification within a lesion in the chest. 2. Other techniques. These include the following: 1. Penetrated radiograph 2. Bronchography 3. Pulmonary angiography and aortography 4. Artificial pneumothorax 5. Bronchial artery angiography. 3. Radiological types which are obvious without further investigation. A few comments will be made on these. 1. Large peripheral mass 2. Pancoast tumour (AU)

Clinical experience with 70 cases of bronchogenic carcinoma in Jamaica

The main clinical features of 70 histologically proved cases of bronchogenic carcinoma seen at the University Hospital during the past six years are described. This disease is on the increase and the frequently seen advanced stage of the illness is a cause for alarm. The absence of physical signs in the early case is stressed and annual mass miniature radiography over the age of 40 should help in this early detection (AU)
