Abstract |
Because carcinoma of breast is known to readily
metastasize to the bone, early detection of metastasis
spread is very important. Two hundred thirty four
consecutive patients who had Tc-99m-MDP bone scans
prior to treatment and during the follow up period were
studied retrospectively to determine the contribution
of the scans to staging, treatment and follow up
examination between Jan. 1980 and Apr. 1987 in Seoul
National University Hospital. 1) Positive bone scan
rates in initial clinical stage I, II, III and IV were
0%, 4%, 14% and 53%, respectively. 2) The higher
clinical stage is, the more cumulative risk of
conversion to positive bone scan is during the same
follow up period. 3) Conversion rate to positive bone
scan in patients with lymph node metastasis is higher
(50%) than those without metastasis (18%) (P〈0.001).
We concluded that the bone scan in primary breast
cancer was very useful to evaluate initial clinical
stage and to perform the follow up examination, |
