CHICAGO -- A theoretical analysis of the use of mammography to screen women aged 70-79 for breast cancer has revealed that such screening would cost $16,948 per year of life saved, investigators reported at the annual meeting of the Radiological Society of North America.
This figure compares favorably with those for other screenings and treatments. For example, cervical cancer screening costs $12,000 per year of life saved; renal dialysis, $46,000 per year of life saved; and cholesterol treatment, $154,000 per year of life saved.
Previous studies and current clinical consensus support the benefits of mammographic screening in women aged 50-70 years, Dr. Colin Poon and his colleagues at the State University of New York Upstate Medical Center, Syracuse, N.Y., noted. But the cost effectiveness of screening women older than 70 years has previously been unclear.
Age is the strongest risk factor for breast cancer, so older women might be expected to benefit the most from screening. Still, age is associated with comorbidity and fewer remaining years in the natural life span, factors that could potentially eliminate the benefit of screening.
The investigators conducted a decision analysis using a Markov model. All women were assumed to be living ...
