A PRILEMARY REPORT ON DIAGNOSIS OF BONE METASTASES WITH RADIONUCLIDE BONE SCANNING IN POSOPERATIVE PATIEN TS WITH BREAST CANCER

42 patients with breast cancer who had already undergons mastectomv reccived whole bone scanning and X-ray films. Follow-up was available for all 42 cases ran ging from 6 to 24 months. Among 21 patients with no pain 14 cases were positive in whole bone scanning; 7 negative. Among them 2 cases were confirmed skeletal metastases during followup. Among 21 patients with pain 16 cases were positive in whole hone scanning, 5 egative. Among them 9 cases were confirmed skeletal metastases during follow-up. The above results showed that positive accuracy rate of bone scanning was 36.6 per cent(11/30) without false positive. And positive accuracy rate of X-ray bone film was 77.3％ (7/9) with false positive (2 cases) and false negative (4 cases) In summary radionuclide bone scanning is a method of finding and diagnosing metastatic bone lessions for postoperative patients with breast cancer. In combination with X-ray examination, it has higher diagnostic reference value but its considerable false positive rate (63.4％) should be analysed further
