Research Abstract

滑膜肉腫、類上皮肉腫、悪性ラブドイド腫瘍におけるDysadherin、E-cadherinの発現:滑膜肉腫(以下SYT)92例、類上皮肉腫(以下ES)46例、悪性ラブドイド腫瘍(以下MRT)6例についてDysadheripおよびE-cadherinのタンパク発現を免疫染色にて検討した。また、腫瘍凍結材料入手可能であったSYT30例、および細胞株、SYT2株、ES4株、MRT4株について、DysadherinおよびE-cadherinのmRNA発現量について、TaqManPCRにて検討した。
Dysadherinタンパク発現とE-cadherinタンパク減弱との相関については、SYTでは有意差(P=0.0004)を認めたが、ESおよびMRTでは有意差を認めなかった。また、Dysadherinタンパク発現と予後との関連性については、SYT(P=0.0411)、ES(P=0.0004)と有意差を認めた。尚、MRTについて、Dysadherinタンパク発現は全て陰性であった。さらには、Dysadherinのタンパク発現とmRNA発現との相関については、SYTでは有意差(P=0.0001)を認め、ES、MRTについては相関を示唆する結果を得た。
SYT、ESについてはDysadherinタンパク発現が予後不良因子として重要であり、Dysadherinに対する分子標的治療の有用性が考えられた。最も高悪性度のMRTにおいては、Dysadherinタンパク発現は無く、予後不良因子としてその他の要因の関与が高いことが考えられた。また、ES(特に近位型)とMRTとは組織学的鑑別が困難であるが、Dysadherinの免疫染色が有用な手法になりえることが示唆された。
