Smoking, Prostate Cancer a Deadly Mix06/21/11
TUESDAY, June 21 (HealthDay News) -- Smokers diagnosed with
prostate cancer are more likely to have the cancer recur after
treatment and are more likely to die than non-smokers, a new study
The study included 5,366 men in the Health Professionals
Follow-Up Study who were diagnosed with prostate cancer between
1986 and 2006. There were 1,630 deaths in this group of men,
including 524 (32 percent) from prostate cancer and 416 (26
percent) from cardiovascular disease. There were 878 cases of
prostate cancer "biochemical recurrence," the researchers said.
Compared with non-smokers, smokers had an increased risk of
biochemical recurrence and were more likely to die from prostate
cancer, cardiovascular disease and all causes. A greater number of
cigarette pack-years was associated with an increased risk of death
from prostate cancer, cardiovascular disease and all causes, but
was not linked with biochemical recurrence, the researchers
The risk of death from prostate cancer for men who had quit
smoking for 10 or more years was similar to that of men who never
The study appears in the June 22-29 issue of the
Journal of the American Medical Association.
"In summary, smoking at the time of diagnosis was associated with substantially increased overall mortality and prostate cancer mortality and recurrence. Ten-year quitters had risks similar to never smokers," lead researcher Stacey A. Kenfield, of the Harvard School of Public Health, and colleagues wrote in a Harvard news release.
"These results provide further support that smoking may increase risk of death from prostate cancer," the study authors concluded.
