A new study suggests that high degree of accuracy is detected by preoperative breast MRI when it is applied to a diverse group of fresh cancer patients. When applied to diverse population, the otherwise occult cancer shows higher degree of accuracy. This study has been published in the January issue of the American Journal of Roentgenology.
This result is an outcome of the study carried out at the University of Washington and Seattle Cancer Care Alliance in Seattle, WA.
592 patients diagnosed with recent breast cancer were reviewed under the study as they went through preoperative breast MRI. Cancer yields were computed and compared using the chi-square test across patient age, tumor type, density of breast, receptor status and lymph node status. Data of over 570 patients was analyzed after calculating their biopsy rates and positive predictive values of biopsy.
The findings showed that use of preoperative breast MRI in newly diagnosed cancer patients resulted in an added cancer yield of 12%. It is pretty higher than the added cancer yield of .08 to 6.7% that is seen with high risk screening breast MRI (a much more accepted indication of breast MRI).
Robert Gutierrez, MD and prime author of the study says that their patient population represents broader diagnostic and diverse population that results from the practice pattern at their site of routinely performing preoperative breast MRI in newly diagnosed cancer patients.
