abstract = {To date, only four small studies have investigated the
effects of adjuvant chemotherapy for breast cancer on the
microstructure of cerebral white matter with magnetic
resonance imaging (MRI). These studies, which were conducted
shortly up to 10 years post-treatment, showed that
chemotherapy is associated with focal loss of
microstructural white matter integrity. We investigated the
long-term effect of chemotherapy on white matter
microstructural integrity by comparing the brains of
chemotherapy-exposed breast cancer survivors to those of a
population-based sample of women without a history of
cancer.Diffusion tensor imaging (DTI) MRI (1.5 T) was
performed in 187 CMF (cyclophosphamide, methotrexate, and
5-flourouracil) chemotherapy-exposed breast cancer
survivors, mean age 64.2 (sd = 6.5) years, who had been
diagnosed with cancer on average 21.2 (sd = 4.4) years
before, and 374 age-matched cancer-free reference subjects
from a population-based cohort study. Outcome measures were
whole-brain microstructural integrity as measured by
fractional anisotropy and mean/axial/radial diffusivity and
focal white matter integrity, which was analyzed with
tract-based spatial statistics. All analyses were adjusted
for age, cardiovascular risk factors, education, and
symptoms of depression.No significant group differences were
observed in white matter integrity. However, within the
breast cancer survivors, time since treatment was inversely
associated with lower global and focal white matter
integrity.This cross-sectional study suggests that among
chemotherapy-exposed breast cancer survivors white matter
microstructural integrity deteriorates with accumulating
time since treatment. This warrants further investigation.},
