This study is a standardized incidence ratio (SIR) analysis of cancer incid
ence of licensed pesticide applicators in Florida, compared with that of Fl
orida's general population. Through extensive data linkages, 33,658 applica
tors were assembled who had 1266 incident cancers and 279,397 person-years
from January 1, 1975, to December 31, 1993. Among males, prostate cancer (S
IR = 1.91; 95% confidence interval [CI], 1.72-2.13) and testicular cancer (
SIR = 2.48; 95% CI, 1.57-3.72) were significantly elevated. No confirmed ca
ses of soft tissue sarcoma (STS) were found, and the incidence of non-Hodgk
in's lymphoma was not increased. There were few female applicators; neverth
eless, cervical cancer incidence (SIR = 3.69; 95% CI, 1.84-6.61) was signif
icantly increased, while the incidence of breast cancer was significantly d
ecreased. Cancers that have been associated with estrogen disrupters were f
ound in male, but not female, pesticide applicators. The lack of soft tissu
e sarcoma is at odds with prior literature associated with the use of pheno
xy herbicides.
