Biopsy Rates Remain Steady Despite New Technology

Hopefully, it will be a benign result

Karthik Ghosh, M.D., M.S., of the Mayo Clinic, Minnesota, and colleagues, reviewed the medical records of women 18 years and older using the resources of the Rochester Epidemiology Project which indexes all inpatient and outpatient medical care provided to residents of Olmsted County, Minnesota.

The rate of utilisation of biopsy was calculated as the number of biopsies performed (except when multiple biopsies were performed on the same breast at one time) compared with the number of women in Olmsted County.

The researchers identified 2,878 biopsies performed on 2,521 women residing in Olmsted County during the study period. “The overall, age-adjusted, annual utilisation rate of breast biopsies was 62.6 percent per 10,000 women and remained fairly constant throughout the study period,” the authors write. “There was no significant change in the trends in breast biopsy utilisation before or after the introduction of the core-needle breast biopsy procedure in 1992.

Utilisation rates for women aged 18 to 39 years, 40 to 49 years, and 50 years and older remained stable throughout the study period. The researchers found that the ratio between results that indicated a malignancy and those that did not remained stable throughout the study at one malignancy for every 2.2 benign results.

“Breast biopsy utilisation rates remained stable throughout the study, although the biopsy technique itself changed with increasing utilisation of image-guided core-needle biopsies” the authors write. The benign-malignant ratio also remained stable despite the change in biopsy techniques. A multidisciplinary breast practice, along with established guidelines for breast biopsy, can ensure the appropriate use of new technology and thereby improve patient care.”; Source: American Medical Association (AMA)
