MRIs may
be a better screening method than mammograms for women with breast
cancer in their family history or otherwise genetically predisposed
to the disease, according to European researchers.
Reporting
at the annual meeting of the American Society of Clinical Oncology,
researchers said two studies comparing the screening methods in
high-risk women found MRIs twice as sensitive as a mammogram in
identifying early breast cancer.
In the German
study, 45 patients out of 462 developed breast cancer over a five-year
period. MRI scans detected 96.1 percent of the tumors, compared
to 42.8 percent detected by mammograms.
"We were
picking up very small lesions," said Dr. Christiane Kuhl,
associate professor of radiology at the University of Bonn and
lead author of the German study.
A Dutch multicenter
study found that MRIs detected 71 of the tumors compared to 36
percent detected by mammograms.
Jan G.M.
Klijn of Erasmus Medical Center in Rotterdam, one of the researchers,
said MRIs would be useful in picking up aggressive cancers found
in some women.
"We recommend
the routine use of MRI in addition to mammography especially in
women with proven gene mutations because these women generally
develop rapidly growing tumours and show the lowest sensitivity
to mammography because of their young age and dense breast tissue,"
Klijn said.
