The expression of cyclooxygenase-2 (COX-2) and its prognostic value in uveal melanoma was examined.
Paraffin-embedded sections from 32 clinicopathologically well-characterized cases of primary uveal melanoma were immunohistochemically stained for COX-2. COX-2 expression was evaluated in terms of both the intensity and the extent of staining for each tumor. A COX-2 score encompassing both intensity and extent was also calculated for each specimen.
29 specimens (90.6%) contained moderate or intense positive immunoreactivity for COX-2. A statistically significant association (p<0.05) between COX-2 expression (intensity and score) and metastatic death was established.
Upregulation of COX-2 expression appears to be associated with poor prognosis in uveal melanoma.
研究环氧化酶-2(COX-2)在葡萄膜黑色素瘤中的表达及其预后价值。
对32例临床病理特征明确的原发性葡萄膜黑色素瘤石蜡包埋切片进行COX-2免疫组织化学染色。根据每个肿瘤的染色强度和范围评估COX-2表达。还为每个标本计算了一个包含强度和范围的COX-2评分。
29个标本(90.6%)对COX-2呈中度或强阳性免疫反应。COX-2表达(强度和评分)与转移性死亡之间建立了统计学上的显著关联(p<0.05)。
COX-2表达上调似乎与葡萄膜黑色素瘤的预后不良有关。
