title: Thoracic surgical problems in asbestos-related disorders.
abstract: Among 1,577 persons with asbestos exposure followed up from 3 to 30 years, 113 had thoracic surgical procedures for asbestos-related disorders. Twenty-six individuals suspected of having asbestosis with atypical features underwent open-lung biopsy; a different disease was revealed in 14. Most of the 29 patients with mesothelioma had a small thoracotomy for diagnosis only; chemotherapy in half of them proved entirely ineffective. Experience with 23 patients with bronchogenic carcinoma did not differ from that in persons not exposed to asbestos. Problems of causal relationship are discussed. Most of the 68 individuals with benign asbestos pleural effusion had no symptoms, but because of recurrence, 15 were operated on for decortication or for possible mesothelioma. Hyaline plaques often were mistaken for lung, rib, or diaphragmatic tumors, and sometimes mesothelioma was suspected. Operative intervention in the 24 patients with plaques could have been avoided by obtaining a more detailed occupational history and reviewing previous chest roentgenograms, which invariably showed identical or smaller plaques from 2 to 17 years earlier.
