以下、具体的に本発明について説明する。
がん研究会の倫理審査委員会にて承認を受け、症例の収集、解析を行った。BPDCNあるいは以前の診断名であるblastic NK-cell lymphoma(芽球型NK細胞リンパ腫)と診断された症例について、英語もしくは日本語の論文、学会発表等を行っている日本国内施設や、その他協力機関に協力を依頼し、各施設でBPDCNと診断された症例の未染色標本、各施設で保存している場合には凍結検体、および臨床情報を収集した。最終的に56施設から153例を収集した。
まず、BPDCNと確定された115症例についての細胞形態の解析結果を示す。細胞形態は、HE染色により評価した。図1に示すように、クロマチン繊細で中等大の不整形核と少量から中等量の細胞質を持ち、核小体は無いか小さいものが単独か複数みられるという教科書的典型例群(以下、classical群という。図1(B))および、それとは大きく異なり、類円形空胞状の核、好塩基性で中等量の細胞質と光輝性の大きな中心性核小体を持つ免疫芽球(immunoblast)に似るがクロマチンが繊細なimmunoblastoid cellを主体とする症例群(以下、immunoblastoid群という。図1(A))が認められた。
次に、免疫染色の結果を示す。ホルマリン固定パラフィン包埋検体を4μmに薄切し、BPDCNの診断適格基準として採用したCD4、CD56、CD123、TCL1、BDCA2の抗体の他、MYC、CD2AP、Bcl11A、Lysozyme、Myeloperoxidaseに対して免疫染色を行った。評価はおもに陽性腫瘍細胞数で行い、染色強度は考慮しないこととした。
4μm厚にスライスしたホルマリン固定パラフィン包埋検体未染色切片に対し、FISH解析を行った。Bacterial artificial chromosome(BAC)クローンから作製したDNAプローブを用いた。ハイブリダイズさせたスライドは、4',6-diamidino-2-phenylindole(DAPI)で対比染色を行い、蛍光顕微鏡 BX51(Olympus)を用いて観察した。判定が可能な腫瘍細胞の70%以上でシグナルのスプリットが認められた場合を陽性、10%以上70%未満の場合をheterogeneous、10%未満であった場合を陰性とした。8q24に遺伝子座を持つMYC、6p21に遺伝子座を持つSUPT3Hに着目してプローブを設計した。なお、SUPT3Hは、8q24再構成のパートナーとして一例報告されている遺伝子である。使用したBACクローンは下記のとおりである。
MYC(赤):CTD-2369J14、RP11-161B19、RP11-195G18、RP11-69H6、CTD-2384G12、RP11-420E20、CTD-3089D15、CTD-2527N12
SUPT3H(緑):RP11-342H9、RP4-669F6
SUPT3H(青):RP11-315C4、CTC-328A8
SUPT3H(赤):RP11-213I18、RP1-244F24、CTD-2515K5
MYCに関する総合分類(MYC classification)として、MYC免疫染色陽性かつ、MYC split FISH陽性の場合をMYC陽性(MYC+)群、MYC免疫染色陰性かつMYC split FISH陰性の場合をMYC陰性(MYC-)群と定義した。どちらにもあてはまらない症例は、MYC atypical(MYCa)群とした。
MYC+群とMYC-群の年齢、性別、初回治療(化学療法、放射線治療)、病変部位、皮膚病変の正常、分布、末梢血所見などの患者背景を比較したところ、年齢、肝臓病変の有無、ヘモグロビン値、皮膚病変の性状、造血幹細胞移植の施行率に有意な差が見られた(表2)。年齢中央値を比較すると、MYC+群が71歳(37~83歳)、MYC-群が64歳(3~88歳)とMYC+群の方が有意に高かった(P=0.022)。18歳未満の小児例はMYC-群に5例含まれたが、MYC+群にはみられなかった。このように、MYC+群とMYC-群の間では患者年齢にも違いがあることが明らかとなった。
次に染色体解析(G分染法)の結果をまとめた。染色体解析の結果は57例で得られており、MYC+群では17/20例(85%)、MYC-群では11/30例(37%)、MYCaでは1/4例(25%)、MYC評価不能例では2/3例、合計31例(54%)で何らかの異常が検出された。57例の染色体解析結果を表4に示す。なお、G分染法は常法により行っている。
BPDCNが、MYC発現によって、大別されることから、MYC発現を抑制することによって、BPDCNのMYC+群(細胞形態immunoblastoid群)の増殖が抑制できる可能性がある。そこで、MYC高発現のBPDCN培養細胞を用いて解析を行った。
オーロラキナーゼの発現亢進は、白血病などの造血器腫瘍で認められており、MYCの過剰発現を認める腫瘍細胞でMYC過剰発現とオーロラキナーゼ阻害薬の合成致死性を示す報告(非特許文献13)や、肝細胞癌においてMYCとオーロラAキナーゼのタンパク質相互作用をオーロラA阻害薬で阻害するとMYCの分解と細胞死が誘導されることが示されている(非特許文献14)。
