Unsuspected exposure to asbestos and bronchogenic carcinoma.

Two hundred and fifty men admitted to a thoracic surgical centre and matched controls were questioned in detail about their occupations after leaving school and their smoking habits. Of 201 men with confirmed bronchial carcinoma 58 gave a history of occupational exposure to asbestos, whereas only 29 out of 201 men matched for age and residential area who were admitted with other diseases gave such a history. This difference was statistically highly significant. The usual association of bronchial carcinoma with heavy smoking was observed, but asbestos exposure increased the risk of carcinoma whatever the level of smoking. These results are consistent with the hypothesis that asbestos exposure and the level of smoking act independently in causing bronchial carcinoma. The patients with carcinoma who had been exposed to asbestos presented on average three years earlier than those who had not been exposed. Asbestos regulations have eliminated the risk of exposure to workers in scheduled industries, so asbestos-induced diseases will probably be increasingly found among the many workers who have had incidental exposure to asbestos. It is therefore important to take a full occupational history.

Pleuropneumonectomy in the management of diffuse malignant mesothelioma of the pleura. Experience with 29 patients.

An analysis is made of the results of pleuropneumonectomy for diffuse malignant pleural mesothelioma in 29 patients and a comparison is made with the results of non-surgical treatment in a further 17 patients. A system of tumour staging is proposed, and the results are correlated with tumour stage and with histological type. Pleuropneumonectomy does not appear materially to affect the course of the disease in cases of mixed epithelial and mesenchymal histological type. However, stage I cases of pure epithelial histological type appear to carry a better prognosis, especially those whose histological structure consists entirely of abundant oedematous mucoid stroma with loosely arranged tumour cells. It is suggested therefore that only epithelial cases should be subjected to pleuropneumonectomy. Means of reducing operative mortality are discussed and alternative methods of treatment described.
