Update of the Texaco mortality study 1947-93: Part II
…colleagues in their update of the Texaco mortality study. The author argued that refinery workers as a group have had lower lung cancer rates than the general population, so maintenance workers exposed to asbestos should be…

An association between postoperative radiotherapy for primary breast cancer in 11 National Surgical Adjuvant Breast and Bowel Project (NSABP) studies and the subsequent appearance of pleural mesothelioma
…Using national registry (SEER) rates, 0.80 cases were expected among irradiated women, a relative risk of 3.74 compared with the general population. Among non-irradiated women, 1.13 cases were expected and none occurred…

Asbestos-related cancers in refinery workers in the Australian petroleum industry
…77 (95% confidence interval = 1.95-6.59). The incidence of lung cancer was significantly lower than that in the general male population. Lung cancer incidence was higher in maintenance workers than in nonmaintenance workers…

Canada, chrysotile and cancer: Health Canada's Asbestos International Expert Panel report
…mesothelioma and asbestosis. Describing other studies, the author reported a general consensus that chrysotile is less potent than amphiboles for mesothelioma, by a highly uncertain amount. The author called the evidence of a difference for lung…

Quantitative analysis of asbestos burden in a series of individuals with lung cancer and a history of exposure to asbestos
…Seventeen of the 20 cases were positive for ferruginous bodies (which were morphologically consistent with asbestos bodies). Five of these were found to have concentrations within the range used in our laboratory for the general population (

Occupational exposure and laryngeal and hypopharyngeal cancer risk in central and eastern Europe
…For laryngeal cancer, the odds ratio for ever exposure to asbestos in general was 0.86 (95% CI 0.51 to 1.45), and for chrysotile asbestos it was 0.78 (0.44 to 1.40…

Thoracoscopic palliative treatment of malignant pleural effusions: results in 273 patients
…110 (40.3%), and bilateral in 27 (9.9%). Thoracoscopy was performed under general anaesthesia in all patients. Pleural biopsy was performed in two thirds of the patients (70.7%). Pleurodesis was produced by instillation of…

Tumor necrosis correlates with angiogenesis and is a predictor of poor prognosis in malignant mesothelioma
…analyzed together, necrosis was not an independent predictor of survival. Cell type, general physical condition (performance status) and blood vessel count were. Necrosis did add information to two existing prognostic scoring systems, EORTC and CALGB. The…

Current controversies regarding the role of asbestos exposure in the causation of malignant mesothelioma: the need for an evidence-based approach to develop medicolegal guidelines
…no new data. The authors described Bradford Hill's criteria for judging causation and criticized the 1997 Helsinki criteria as giving only very general and internally contradictory answers to questions raised in court. They then posed…
