Loughry CW, Sheffer DB, Price TE, Morek WM, Einsporn RL. Use of biostereometric analysis as a screen for breast cancer. Invest Radiol 1991;26:528-533.Biostereometric analysis, a photographic surface imaging technology that is noninvasive, was tested for its effectiveness in selecting breast pathology in a sample of 1000 female subjects, including 80 with cancers, 635 normals, and 285 with benign breast conditions. These individuals were recruited from the population of women undergoing routine mammographic examination. The project was designed specifically to determine whether biostereometric analysis could identify the individuals in the sample with malignant breast disease in the hope of providing information to aid in future development of a breast cancer screening protocol. The overall sensitivity of the method for cancers of all sizes was 76%. Biostereometric analysis was 85% sensitive for selection of cancers in the subjects over 50 years of age, and identified 80% (4 of 5) of the subjects with clinically confirmed breast cancers less than 1 cm in size. The method was 69% specific, but identified benign breast disease in only 51% of cases
