digonositic features of lung cancer in coal miners

The diagnosis of lung cancer in coal-miners with ...

The diagnosis of lung cancer in men who have worked in coal-mines is complicated by the clinical and radiographic similarities of malignant and pneumoconiotic lesions. Cases are reported which illustrate some of the problems, namely the similarity between peripheral lung cancer and coal-workers' massive fibrosis, between lung cancer and Caplan ...

The Diagnosis of Lung Cancer in Coal-Miners with ...

Generally this paper deals with the same subject as the one above but it is based on experience of cases occurring among coal-miners in another coalfield in Great Britain, namely, South Wales, where the incidence of PMF is very high. Details are given of 5 illustrative cases. The author reaffirms from his experience that the clinical distinction between lung cancer and PMF is uncertain, for ...

Lung Cancer in Coal-Miners Occupational

In a study of coal-miners suffering from lung cancer two features of special interest are recorded. The difficulties in diagnosis are illustrated by case reports. The two-year survival rate after surgical removal of the tumour is significantly better in coal-miners than in non-miners. After operation 87% of coal-miners were alive two years later, compared with only 36% of other patients ...

Lung cancer in miners Thorax

The clinical, histological, and biological features of 157 lung cancers in coal miners and ex-miners are presented. In most respects—age, bronchoscopic appearances, histological type, and symptoms —the two groups are similar. A high incidence of dyspnoea in the miners was attributed to the concurrence of chronic bronchopulmonary disease. A striking feature was the lower frequency with ...

Population Cancer Risks Associated with Coal Mining:

2013-8-15  Background Coal is produced across 25 states and provides 42% of US energy. With production expected to increase 7.6% by 2035, proximate populations remain at risk of exposure to carcinogenic coal products such as silica dust and organic compounds. It is unclear if population exposure is associated with increased risk, or even which cancers have been studied in this regard.

Mortality from lung cancer in U.S. coal miners.

The vital status of 94% of a group of 3726 miners has been ascertained at the end of a 10-year study period. 451 deaths occurred. Death certificates were examined and 24 deaths were found to have neoplasm of bronchus or lung as the underlying cause. Using 1968 death rates of males in the United States, the authors estimate that 36 lung cancer deaths were expected.

The 3,341 NCWAS cases had an average age of 62 +/- 11 years, with an underground mining history of 26 +/- 14 years. Nearly 72% of the miners had a smoking history with an average of 25 +/- 19 pack years. The age and mining histories were similar in the 331 group of lung cancer cases and the subgroup of 171 cases with primary lung cancer.

Silicosis and Coal Workers’ Pneumoconiosis

2019-7-21  Silicosis in coal miners is usually found in conjunction with simple CWP and rarely as an isolated form of pneumoconiosis. It is difficult to distinguish between silicosis and CWP on chest radiography. The prevalence of silicosis in coal miners can be reliably determined only in autopsy studies. In the National Coal Workers’ Autopsy Study ...

Silica Adds to Respirable Dust Concerns Coal Age

2016-1-22  Exposure to silica in coal mines is the major cause for the development of silicosis and lung cancer, and a significant contributor to black lung. Silica is an inherent part of the dust present in a coal mine, but the silica content in the dust is highly variable both in space and over time. Because of this variability and the serious health ...

Abstract Excluding reports on coal miners and foundrymen, which are difficult to interpret, there have been at least 39 useful studies of mortality since 1978 in workers potentially exposed to crystalline silica, and some 16 studies of persons compensated or hospitalized for silicosis. Virtually all of the latter show evidence of an approximately threefold increase in lung cancer risk, perhaps ...
