Feline malignant lymphoma occurs commonly in domestic cats and may serve as a model for non-Hodgkin 's
lymphoma in, humans. Several studies have suggested that smoking may increase the risk of non-Hodgkin 's
lymphoma. To evaluate whether exposure. To household environmental tobacco smoke (ETS) may increase the
risk of feline, malignant lymphomaThe authors conducted a case-control study of this relation in 80 cats with
malignant lymphoma and 114 controls with renal. Disease diagnosed at a large Massachusetts veterinary
teaching hospital between 1993 and 2000. Owners of all subjects were. Sent a questionnaire inquiring about the
level of smoking in the household 2 years prior to diagnosis. After adjustment. For age and, other factors the
.Relative risk of malignant lymphoma for cats with any household ETS exposure was 2.4 (95 percent confidence
interval: 1.2 4.5,,). Risk increased with both duration and quantity, of exposure with evidence of a linear trend.
Cats with 5 or more years of. ETS exposure had a relative risk of 3.2 (95 percent confidence, interval: 1.5 6.9; P
for trend = 0.003) compared with those in nonsmoking households. These findings suggest that passive smoking
may increase the risk of. Malignant lymphoma in cats and that further study of this relation in humans is warranted.
