To determine whether image cytometry (ICM) is advantageous for clinical DNA analyses of tumor cells, nuclear DNA contents measured by ICM were compared with those by flow cytometry (FCM), using 46 samples of non‐small cell lung cancers. ICM was performed on smear specimens of fresh materials (f‐ICM) and cell suspensions obtained from paraffin‐embedded tumors (p‐ICM). The same cell suspensions were also analyzed by FCM (p‐FCM). Aneuploid rates/coefficient of variation (CV) of f‐ICM, p‐ICM, and p‐FCM were 76.1/4.90, 71.7/5.01 and 60.9/5.31%, respectively. There was a high correlation in the DNA indices between p‐ICM and p‐FCM (r=0.80). In the comparative DNA analysis, there were seven discordant samples. Six of them were estimated as aneuploid by p‐ICM, but they were miscounted as diploid or undefinablc (impossible) by p‐FCM. This was caused by measuring condensed nuclei or debris. All “impossible” samples in p‐FCM were squamous cell carcinoma with necrosis. In cell cycle analysis, the S and S+G2/M phase fractions in diploid samples were higher in p‐ICM than those in p‐FCM (P< 0.005), because the GO/G1 phase (2N) fraction presented by FCM was composed of cancer and non‐malignant cells in diploid cancers. In ICM, they can be separately measured by means of morphological selection. These findings indicated that ICM is superior to FCM, especially for the practical DNA measurement of a few cancer cells and in the evaluation of the proliferation rates.

背景:節状構造および粘液球 (あるいは硝子球) は, 頸部領域では腺様嚢胞癌をはじめとした唾液腺腫瘍を示唆する所見である. 今回われわれは, 穿刺吸引細胞診で節状構造・粘液球を認め, 腺様嚢胞癌との鑑別に苦慮した甲状腺癌の1例を経験したので報告する.症例:患者は77歳女性.慢性腎不全に対する透析導入目的で入院した際, 右頸部腫瘤を発見された. 画像上, 甲状腺右葉内に直径3cmの腫瘤があり, 右頸部リンパ節, 両側肺には多発転移が認められた. 穿刺吸引細胞診では, 甲状腺腫瘤とリンパ節の検体は同様の細胞像を示していた. 腫瘍細胞は集塊を形成し, 集塊内には節状構造や粘液球が認められた. 腺様嚢胞癌が疑われたが, 唾液腺に原発巣はみつからなかった. 針生検標本でも同様に, 腫瘍細胞は筋状構造を形成していたが, 腫瘍細胞間にはコロイド様物質を含む微小濾胞が散見された. さらに, 免疫組織化学的にも腫瘍細胞はthyroglobulin, thyroid transcription factor-1 (TTF-1) に陽性であったため甲状腺癌と診断した.結論:頸部腫瘍の細胞診像で節状構造や粘液球が認められたときは, 腺様嚢胞癌をはじめとする唾液腺腫瘍が強く疑われる.しかし, 本例のように甲状腺腫瘍でもこれらの所見が出現することがあるので, 臨床像, 検査所見を総合的に判断する必要がある.

早期肺扁平上皮癌組織表層の角化の程度と, 表層細胞の核形態および腫瘍進展度との関係を検討した. 対象は切除した早期肺扁平上皮癌32例の33病巣で, これらを腫瘍表層の角化の程度によって, 明らかな角化のない軽度角化7病巣, 角化は明らかだが最表層の数層に留まる中等度角化8病巣, 角化の著明な高度角化18病巣に分類した. 角化の明らかな中等度ないし高度角化8病巣が, 異型の少ない小型核を持つ角化細胞で覆われていた. これらは細胞診にて見逃され易いものである. 高度角化18病巣中, 中心型が14病巣, 気管支軟骨外進展が7病巣で, いずれも3型中最も多かった. 一方, 軽度角化7病巣では, 表層進展型が5病巣, 20mm以上の大きさの病巣が4病巣と多数を占めた. 従って, 高度角化病巣には中心型で深達進展高度なものが多く, 軽度角化病巣には表層進展型で比較的広がりの大きいものの多いことが知られた.
