Cancer incidence of dry cleaning, laundry and ironing workers in Sweden

The non-Hodgkin lymphomas: A review of the epidemiologic literature

“…Weak, nonsignificant inverse associations have been reported for dry cleaners in Nordic country cohorts. 263,270,271 A nonsignificant positive association was found among male bookbinders, printers, photoengravers and typesetters (SIR 5 2.24, 95% CI: 0.96-4.41). 272 Other occupational groups for which nonsignificant findings have been reported include synthetic abrasive product workers, 273 266,295 Several case-control studies have found significant associations of NHL risk with various occupational categories, including chemical manufacturing maintenance subgroups, 236 cigarette factory workers, 296 electrical fitters, 297 rail and road transport workers, 266 accountants, 266 secretaries, 266 photographic lab workers, 266 carpenters, 21,214 managerial and professional workers 176,260 and printing workers.…”

“…143,266 No significant findings with respect to NHL risk have been reported among veterinarians. [630][631][632] Blair et al 631 observed a significant excess proportion of NHL deaths among small animal practitioners (PMR 5 3.28), but not among other practitioners (PMR 5 0.91). Results for having household pets have been mixed, with significant and nonsignificant associations above 118,143,153,214 and below 29,143 1.0.…”

Exposure to Solvents and Risk of Non-Hodgkin Lymphoma: Clues on Putative Mechanisms

“…NHL cases were classified following the Working Formulation. 4 If the original diagnosis was outside the Working Formulation definitions, the cases was reclassified within the Working Formulation by a pathologist experienced in the field. Following the Working Formulation, chronic lymphocytic leukemia cases were grouped in the ''small lymphocytic consistent with chronic lymphocytic leukemia'' category.…”

“…Subjects who were never exposed to any of the listed chemicals were used as the referent population. 4 For details, see http://training.seer.cancer.gov/ss_module08_lymph_leuk/lymph. …”

“…Other autoimmune diseases (such as, e.g., diabetes type 1, multiple sclerosis, or rheumatoid arthritis) have been associated with the risk of NHL in some studies but not in others (2,3). In relation to environmental exposures, recent studies have suggested an association between NHL and exposure to organic solvents (4)(5)(6)(7). Organic solvents represent a class of chemicals that have been used in many industrial sectors, and exposure is also widespread among the general population.…”
