Abstract |
Bone scans with Tc-99m-MDP (methylene diphosphonate)
were obtained and analysed in 574 from April, 1979 to
June, 1931. Clinical staging was done in all patients
without bone scan information and compared with bone
scan to determine the predictive value of bone
scanning. 1) Primary site of the maligancies were lung
in 152, breast in 97, stomach in 43, colon in 15,
esophagus in 9, liver and pancreas in 11, kidney in 14,
bladder in 27, prostate in 22, thyroid in 20, skin in
11, bone in 9, head and neck in 36, ovary and uterus in
17, hematopoietic and lymphoretic ular system in 33,
nervous system in 10, and others in 9 cases. Primary
site was not defined in 39 cases. 2) Bone scans were
positive in 186 cases(32.4%), which, included 48
cases(31.6%) of lung cancer, 27 cases(27.8%) of breast
cancer, 12 cases(28%) of stomach cancer, 6 cases(40%)
of colon cancer, 6 cases(43%) of kidney tumor, 4
cases(l5%) of bladder cancer, 14 cases(64%) of prostate
cancer, 3 cases(l5%) of thyroid cancer and 66 other
cases. 3) Bone scans were suspicious in 64 cases(11.2%)
which included 29 cases(l9.1%) of lung cancer, 10
cases(l0.3%) of brest cancer, 4 cases(9.3%) of stomach
cancer, one case(7%) of colon cancer, 3 cases(11%) of
bladder cancer, 2 cases(l0%) of thyroid cancer and 15
other cases. 4) Out of 121 cases with early stage of
malignancy (which included 20 cases of lung cancer in
stage Ⅰ, Ⅱ, 38 cases of breast cancer, 13 cases of
stomach cancer, 8 cases of kidney tumor, 14 cases of
thyroid cancer in stage Ⅰ∼Ⅲ, and 6 cases of colon
cancer, 14 cases of bladder cancer, 8 cases of prostate
cancer in stage A∼C, bone scans were positive in 5
cases (4.1%) which included 3 cases of lung cancer one
case of breast cancer and one case of prostate cancer,
and considered as further advanced stage, Out of 121
cases with early stage of malgnancy, bone scans were
suspicious in 21 cases(17.4%) which inlcuded 9 cases of
lung cancer, 4 cases of breast cancer, 2 cases of
stomach cancer, one case of colon cancer, 3 cases of
bladder cancer, and 2 |
