Detection and significance of estrogen receptor and proliferating cell nuclear antigen in tissues of fibrous dysplasia of bone
  【Abstract】 AIM: To investigate the relation between the clinical biological behavior and the expression of estrogen receptor (ER) and proliferating cell nuclear antigen (PCNA) in the tissues of fibrous dysplasia of bone (FDB). METHODS: Ninetyeight cases wrer surgically treated, pathologically confirmed as having fibrous dysplasia and followed up. The primary operation specimens were randomly selected and divided into recurrence group (n=24) and cured group (n=24), children group (n=26) and adult group(n=22). The ER and PCNA in the specimens were detected with monoclonal antibody to ER or PCNA by immunohistochemistry. RESULTS: The general positive expression rate of ER was 56.25%(27/48). The positivity rate in recurrence group was higher than that in cured group (70.83% vs 41.67%, P<0.05) and the positivity rate in children group was higher than that in adult group (69.23% vs 40.91%, P<0.05). The expression of PCNA in recurrence group was higher than that in cured group (P<0.01). The expression of PCNA had a tendency to be higher in children group than that in adult group, but with no statistical significance (P>0.05). CONCLUSION: FDB is relative to the estrogen. The abnormal expression of ER, the disturbance of the regulation of estrogen in bone development and metabolism may be the causes of the onset and recurrence of FDB. The expression of PCNA is related with the recurrence of FDB. PCNA can be used as a reference marker for prognosis of FDB.

  【摘要】 目的: 探討骨纖維結構不良(FDB)病變組織雌激素受體(ER)和增殖細胞核抗原(PCNA)的表達并討論其臨床意義. 方法: 98例FDB患者手術(shù)治療、病理確診并獲隨訪(fǎng). 收集初次手術(shù)切除的標本,隨機從治愈和復發(fā)病例中各抽取24例. 對復發(fā)組(n=24)與治愈組(n=24)、小兒組(n=26)與成人組(n=22)進(jìn)行對比,用單克隆抗體免疫組織化學(xué)方法對病變組織進(jìn)行ER和PCNA檢測. 結果: ER總陽(yáng)性率為56.25%(27/48). 復發(fā)組70.83%(17/24)明顯高于治愈組41.67%(10/24) (P<0.05). 小兒組69.23%(18/26)明顯高于成人組40.91%(9/22, P<0.05). 復發(fā)組PCNA陽(yáng)性表達強度顯著(zhù)高于治愈組(P<0.01),而小兒組PCNA陽(yáng)性表達高于成人組,但無(wú)統計學(xué)差異(P>0.05). 結論: FDB的雌激素相關(guān)性表現為ER異常表達而導致骨發(fā)育及代謝調節紊亂;PCNA陽(yáng)性表達強度與骨纖維結構不良的復發(fā)密切相關(guān),可作為其預后估測的參考指標.

  0引言
  骨纖維結構不良(fibrous dysplasia of bone, FDB)的發(fā)病率居骨與關(guān)節瘤樣病變的首位[1],其臨床表現為,術(shù)后復發(fā)率高,兒童期更具高度復發(fā)傾向和侵襲性,部分病灶呈進(jìn)展性,部分病灶卻長(cháng)期靜止,有些病例反復多次復發(fā),少數可發(fā)生惡變,但泛發(fā)性骨纖維結構不良(Albright綜合征)主要見(jiàn)于女性. 我們檢測骨纖病變組織中雌激素受(estrogen receptor, ER)和增殖細胞核抗原(proliferating cell nuclear antigen, PCNA)的變化并討論其臨床意義.
  1材料和方法
  1.1材料
  標本來(lái)源于197701/199806西京醫院骨科手術(shù)治療的骨纖患者病變組織石蠟埋塊. 選取其中有隨訪(fǎng)結果的98例患者初次手術(shù)標本,根據隨訪(fǎng)結果分成復發(fā)與治愈兩組. 采用隨機數字法各選取24個(gè)標本,共48例. 再根據患者年齡分為:小兒組(≤14歲)26例,成人組(≥15歲)22例. 一抗分別選用法國Immunotech公司產(chǎn)的鼠抗人ER mAb(1∶50)和丹麥DAKO公司產(chǎn)的鼠抗人PCNA mAb(1∶40). 二抗均選用Sigma公司產(chǎn)的生物素標記羊抗鼠IgG. SABC試劑盒(武漢博士德生物工程有限公司).
  1.2方法
  標本連續切片3張,1張HE染色,病理醫師再次確診,2張分
