Immunohistochemical detection of desmosomes in oral squamous cell carcinomas: Correlation with differentiation, mode of invasion, and metastatic potential

Takeshi Harada; Masanori Shinohara; Seiji Nakamura; Makoto Shimada; Masuichiro Oka

An expression of desmosomal glycoprotein 1 (DG 1) was immunohistochemically examined in 77 biopsies and 21 metastatic cervical lymph nodes of oral squamous cell carcinomas (SCC). In the primary tumors the DG 1 expression was significantly reduced at the invasive site of poorly differentiated and highly invasive tumors. In cases of metastases in cervical lymph nodes, the DG 1 staining at the invasive site of the primary tumor was significantly less than that of nonmetastatic cases. The DG 1 expression in the metastatic lymph nodes was as weak as that in the primary tumor. Thus, we suggest that immunohistochemical investigation of DG 1 expression in oral SCC is valuable in predicting tumor behavior.

Mode of tumor invasion in oral squamous cell carcinoma: Improved grading based on immunohistochemical examination of extracellular matrices

Masanori Shinohara; Seiji Nakamura; Takeshi Harada; Makoto Shimada; Masuichiro Oka

To predict the nodal involvement of oral squamous cell carcinoma (OSCC) many investigators have studied the histologic features of primary tumors. However, conventional histologic grading still is not sufficient to provide an objective and practical evaluation. In this study we tried to modify one standard type of histologic grading, namely, mode of invasion (MI), on the basis of the extracellular matrix (ECM) staining pattern.

腫瘍の下顎骨への浸潤状態と組織学的腫瘍浸潤様式ならびに腫瘍における細胞外基質出現状態との関連性について下顎歯肉扁平上皮癌37症例で臨床的, 免疫組織学的に検索した。腫瘍の下顎骨への浸潤状態については, レントゲン検査による下顎骨の吸収様式と吸収程度について検索した。下顎骨の吸収様式と吸収程度は Swearingen と戸塚の分類を用いた。組織学的腫瘍浸潤様式は山本, 小浜の分類を用いた。さらに, MIIIを細胞外基質出現状態によってMIIIaとMIIIbに細分類した。細胞外基質についてはラミニン, タイプIVコラーゲン, ヘパラン硫酸プロテオグリカン, ファイブロネクチン, テネイシン, ビトロネクチン, デコリンについて免疫組織学的に検索した。結果は以下のごとくであった。1) Tの程度と腫瘍の下顎骨への浸潤状態の間に明らかな関連性が認められた。2) 組織学的腫瘍浸潤様式と腫瘍の下顎骨への浸潤状態の間に関連性が認められた。3) レントゲン検査による下顎骨の吸収様式と細胞外基質出現状態との間に関連性が認められた。これらの結果より, これら因子の詳細な解析によって下顎歯肉扁平上皮癌の治療計画を決めるための有用な情報が与えられることが示唆された。
