【摘要】:目的:本研究旨在觀察P16、Ki-67、HMB45在人結(jié)膜惡性黑色素瘤的表達(dá)情況,,并探究它們與結(jié)膜惡性黑色素瘤臨床分期、預(yù)后的關(guān)系。 方法:對中山大學(xué)中山眼科中心2002年4月到2010年7月收治的20例結(jié)膜惡性黑色素瘤患者進(jìn)行臨床資料分析并對患者進(jìn)行電話回訪,觀察其臨床病理特點及分析免疫組化結(jié)果。同時收集20例結(jié)膜色素痣石蠟包埋標(biāo)本作為實驗對照組。采用免疫組織化學(xué)染色技術(shù)觀察P16、Ki-67、HMB45在人結(jié)膜惡性黑色素瘤和結(jié)膜色素痣的表達(dá)情況。根據(jù)美國癌癥聯(lián)合協(xié)會分類法(AJCC)2010年關(guān)于結(jié)膜惡性黑色素瘤的分期標(biāo)準(zhǔn)進(jìn)行臨床分期,統(tǒng)計分析P16、Ki-67、HMB45與結(jié)膜惡性黑色素瘤臨床分期、預(yù)后之間的關(guān)系。 結(jié)果:P16在結(jié)膜惡性黑色素瘤中的陰性表達(dá)率、低表達(dá)率、中高表達(dá)率分別為60%(12/20)、20%(4/20)、20%(4/20);在結(jié)膜色素痣中的陰性表達(dá)率、低表達(dá)率、中高表達(dá)率分別為5%(1/20)、20%(4/20)、75%(15/20)。Ki-67在結(jié)膜惡性黑色素瘤中的陰性表達(dá)率、低表達(dá)率、中高表達(dá)率分別為20%(4/20)、25%(5/20)、55%(11/20);在結(jié)膜色素痣中的陰性表達(dá)率、低表達(dá)率分別為75%(15/20)、25%(5/20)。HMB45在結(jié)膜惡性黑色素瘤中的陰性表達(dá)率、低表達(dá)率、中高表達(dá)率分別為10%(2/20)、15%(3/20)、75%(15/20);在結(jié)膜色素痣中的陰性表達(dá)率、低表達(dá)率分別為90%(18/20)、10%(2/20)。P16、Ki-67、HMB45在結(jié)膜惡性黑色素瘤與結(jié)膜色素痣兩組間的表達(dá)均有統(tǒng)計學(xué)差異(P<0.05)。結(jié)膜惡性黑色素瘤中P16與Ki-67表達(dá)呈負(fù)相關(guān)(r=㧟0.786,P<0.05)。P16與結(jié)膜惡性黑色素瘤臨床分期、預(yù)后呈負(fù)相關(guān)(r=㧟0.618,P<0.05;r=㧟0.491,P<0.05)。Ki-67與結(jié)膜惡性黑色素瘤預(yù)后呈正相關(guān)(r=0.504,P<0.05)。HMB45與結(jié)膜惡性黑色素瘤臨床分期、預(yù)后無關(guān)(X2=2.629,P>0.05;X2=0.317,P>0.05)。 結(jié)論:P16在結(jié)膜惡性黑色素瘤中的表達(dá)低于結(jié)膜色素痣;HMB45、Ki-67在結(jié)膜惡性黑色素瘤中的表達(dá)高于結(jié)膜色素痣。結(jié)膜惡性黑色素瘤中P16與Ki-67的表達(dá)呈負(fù)相關(guān)。P16與結(jié)膜惡性黑色素瘤臨床分期、預(yù)后呈負(fù)相關(guān);Ki67與結(jié)膜惡性黑色素瘤預(yù)后呈正相關(guān)。提示P16和Ki-67可能對預(yù)測結(jié)膜惡性黑色素瘤的預(yù)后有重要意義。
[Abstract]:Objective: to observe the expression of P16, Ki67 and HMB45 in human conjunctival malignant melanoma and to explore their relationship with clinical stage and prognosis of conjunctival malignant melanoma. Methods: the clinical data of 20 patients with conjunctival malignant melanoma admitted to Zhongshan Ophthalmology Center of Sun Yat-sen University from April 2002 to July 2010 were analyzed and the patients were interviewed by telephone. The clinicopathological features and the results of immunohistochemistry were observed. At the same time, 20 paraffin embedded specimens of conjunctival pigmented nevi were collected as experimental control group. The expression of P16, Ki67 and HMB45 in human conjunctival malignant melanoma and conjunctival pigmented nevi was observed by immunohistochemical staining. According to the classification of the American Association of Cancer (AJCC) in 2010, the clinical staging of conjunctival malignant melanoma was carried out. The relationship between P16, Ki67, HMB45 and the clinical stage and prognosis of conjunctival malignant melanoma was statistically analyzed. Results: the negative expression rate and low expression rate of P16 in conjunctival malignant melanoma were 60% (12 鈮
