| Abstract | 「要旨」乳腺腫瘍52例に対し201Tl-chlorideシンチグラフィを施行し, 乳癌の70.5%（初発乳癌69.2%, 再発乳癌80%）に集積陽性像が認められ, 比較的大きなリンパ節転移巣にも集積が認められた. 初発乳癌において, 組織型と201Tl-chlorideの集積程度を比較すると, 乳頭腺管癌, 髄様腺管癌に強く, 硬癌には弱い集積傾向がみられた. 201Tl-chlorideの乳癌への集積は組織型の差もさることながら, 腫瘤の大きさに一致し, 2cm以下の早期乳癌においては集積がみられなかった. 再発乳癌においては, 201Tl-chlorideの集積は良好であり, 201Tl-chlorideシンチグラフィは腫瘤の広がり, 治療効果の判定などに有効であった. 一方, 乳腺の良性腫瘍では全例201Tl-chlorideの集積はみられず, 腫瘤の質的診断に有用であると考えられた. 以上の成績より, 201Tl-chlorideシンチグラフィは乳腺腫瘍の補助診断法として有意義な検査法と考えられた. |

| Abstract | [Summary] Fifty-two patients with breast tumors were scintigraphed with 201Tl-chloride. Each one was given a histological diagnosis after surgery or excisional biopsy. In 39 cases of primary breast cancer, 27 cases (69.2%) showed a positive figure by 201T1- chloride scintigraphy. In five cases of local recurrent breast cancer, four cases (80%) showed a positive figure. In examining each histological type of primary breast cancer, in 10 cases of papillotubular carcinoma, seven (70%) were positive with 201T1-chloride. In 20 patients with medullary tubular carcinoma, 17 cases (85%) revealed a positive figure. In nine cases of scirrhous carcinoma, only three cases (33.3%) were positive. Some cases showed an accumulation in the metastatic lymphnodes of the axilla with 201Tl-chloride. In three cases of phyllodes tumor, two cases (66.7%) were positive. On the other hand, all cases of benign breast tumors showed a negative figure by 201Tl-chloride scintigraphy. As to the uptake ratio of 201Tl-chloride into the breast carcinoma tissue, it was observed that papillotubular carcinoma absorbed 5.8 times as much as normal mammary gland tissue, medullary tubular carcinoma absorbed 4.7 times as much, scirrhous carcinoma absorbed 3.3 times as much as normal mammary gland tissue. In recurrent breast cancer, 201Tl-chloride scintigraphy is a useful procedure in determining the malignant area and in judging the effect of treatment. From the above mentioned results, it was concluded that 201Tl-chloride has specific affinity for malignant breast tumors and it is also very useful tumor-seeking agent to detect the early recurrent breast cancer. |
