| Abstract | 「要旨」骨シンチグラフィ全身およびスポット像から, 450症例, 793乳房(乳癌207例, 非乳腺腫瘍243例)を対象に年代別の女性乳房描出率, ならびに手術前乳癌患者(前述207例中100例)の腫瘍側乳房への集積増加, および腫瘍への集積から診断が可能か否かをretrospectiveに検討した. 非乳腺腫瘍群を年代別にみると30代をピークにその後加齢とともに減少したが, 70代以降も乳房描出が認められた. 授乳等ホルモンの影響が大いに関与していると考えられた. 乳癌群および非乳腺腫瘍群の乳房描出率では平均68%, 30%と明らかに差が認められた. また, 腫瘍側乳房への集積増加は12%に認められたが, 癌の局在診断はきわめて困難であった. しかし, 乳房集積に左右差のある場合は42%の症例に癌が存在したので, 骨シンチグラム読影の際には考慮する必要があると思われた. |

| Abstract | [Summary]Breast cancer incidence rates in Japan have more than doubled in the decade between 1975 and 1985 due to a well-established and affluent Western life-style. One hundred patients having breast cancer, 107 patients having mastectomies, and 243 patients having no breast cancer were reviewed for whole body and spot views of bone scintigraphy with 99mTc-MDP. The frequency of positive breast uptake in patients with no breast cancer showed a maximum in those patients between the ages of 30 and 40, with a progressive rise and fall before and after the peak, respectively. Patients between the ages of 50 and 60 with breast cancer showed a maximum uptake of 83%, while those patients between the ages of 70 and 80 with breast cancer showed an uptake higher than 50%. There was a markedly higher breast uptake ratio in the breast cancer group compared to the breast cancer free group. Although this scanning agent was of no value in recognition of tumor localization from breast uptake, we have to suspect a high incidence of cancer existence whenever there was unilateral increased breast activity. Even though the mechanism of 99mTc-MDP uptake by breast tissue is unknown, breast concentration of 99mTc-MDP appears to be influenced by hormones, especially estrogen. |
