Mass screening for breast cancer in Nagano prefecture has involved inspection?palpation in addition to ultrasonography. Total examinees between April 1988 and March 1995 amounted to about 336, 000 women, of whom about 78, 000 received further examination. These were divided into 4 groups by district (A, B, C, D). Intergroup differences were seen in the numbers of examinees and the rate of further examinations needed, but not in the rate of breast cancer detected. In women who underwent further examination, the breast cancer detection rate differed significantly among the 4 groups. The rate of breast cancer detected by palpation showed no difference, but that detected by ultrasonography did differ among the 4 groups. In terms of diagnostic accuracy of palpation and ultrasonography by district, sensitivity and positive predictability showed no difference, but specificity and accuracy differed significantly between palpation and ultrasonography by district. Sensitivity and positive predictability did not differ, but specificity and accuracy of palpation were higher than for ultrasonography. The proportion of no ultrasonographic diagnosis differed significantly among the 4 groups. It is becoming apparent that the diagnostic accuracy of palpation and ultrasonography by practitioners differs among districts in mass screening for breast cancer in Nagano prefecture. It will be necessary to devise means of resolving these differences in diagnostic accuracy of palpation and ultrasonography.
