【摘要】:目的:本研究旨在觀察P16、Ki-67、HMB45在人結膜惡性黑色素瘤的表達情況,,并探究它們與結膜惡性黑色素瘤臨床分期、預后的關系。 方法:對中山大學中山眼科中心2002年4月到2010年7月收治的20例結膜惡性黑色素瘤患者進行臨床資料分析并對患者進行電話回訪,觀察其臨床病理特點及分析免疫組化結果。同時收集20例結膜色素痣石蠟包埋標本作為實驗對照組。采用免疫組織化學染色技術觀察P16、Ki-67、HMB45在人結膜惡性黑色素瘤和結膜色素痣的表達情況。根據(jù)美國癌癥聯(lián)合協(xié)會分類法(AJCC)2010年關于結膜惡性黑色素瘤的分期標準進行臨床分期,統(tǒng)計分析P16、Ki-67、HMB45與結膜惡性黑色素瘤臨床分期、預后之間的關系。 結果:P16在結膜惡性黑色素瘤中的陰性表達率、低表達率、中高表達率分別為60%(12/20)、20%(4/20)、20%(4/20);在結膜色素痣中的陰性表達率、低表達率、中高表達率分別為5%(1/20)、20%(4/20)、75%(15/20)。Ki-67在結膜惡性黑色素瘤中的陰性表達率、低表達率、中高表達率分別為20%(4/20)、25%(5/20)、55%(11/20);在結膜色素痣中的陰性表達率、低表達率分別為75%(15/20)、25%(5/20)。HMB45在結膜惡性黑色素瘤中的陰性表達率、低表達率、中高表達率分別為10%(2/20)、15%(3/20)、75%(15/20);在結膜色素痣中的陰性表達率、低表達率分別為90%(18/20)、10%(2/20)。P16、Ki-67、HMB45在結膜惡性黑色素瘤與結膜色素痣兩組間的表達均有統(tǒng)計學差異(P<0.05)。結膜惡性黑色素瘤中P16與Ki-67表達呈負相關(r=㧟0.786,P<0.05)。P16與結膜惡性黑色素瘤臨床分期、預后呈負相關(r=㧟0.618,P<0.05;r=㧟0.491,P<0.05)。Ki-67與結膜惡性黑色素瘤預后呈正相關(r=0.504,P<0.05)。HMB45與結膜惡性黑色素瘤臨床分期、預后無關(X2=2.629,P>0.05;X2=0.317,P>0.05)。 結論:P16在結膜惡性黑色素瘤中的表達低于結膜色素痣;HMB45、Ki-67在結膜惡性黑色素瘤中的表達高于結膜色素痣。結膜惡性黑色素瘤中P16與Ki-67的表達呈負相關。P16與結膜惡性黑色素瘤臨床分期、預后呈負相關;Ki67與結膜惡性黑色素瘤預后呈正相關。提示P16和Ki-67可能對預測結膜惡性黑色素瘤的預后有重要意義。
[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
