原发性粘膜黑色素瘤(MM)是一种罕见的、侵袭性的肿瘤,预后较差。迄今为止,MM的预后标记物很少被明确定义。本研究的目的是阐明p53和p16蛋白在预测中国MM患者临床预后方面的预后价值。我们共从活检标本中提取59个MM样本,并通过免疫组织化学方法评估p53和p16蛋白的表达。采用Cox回归分析研究这些蛋白与MM患者总生存率的关系。p16表达增加与3年生存率降低显著相关(P=0.039)。p53表达增加与1年(P=0.025)和2年生存率降低相关(P=0.037)。p53和p16蛋白表达的增加可能是这些患者治疗的有用预后指标。
Primary mucosal melanoma (MM) is a rare, and aggressive, neoplasm with a poor prognosis. To date, few prognostic markers of MM have been well-defined. The aim of this study is to clarify the prognostic value of p53 and p16 proteins in predicting the clinical outcome of Chinese patients with MM. A total of 59 MM samples were contained from biopsy specimens, and, expressions of p53 and p16 proteins were assessed by immunohistochemistry. Cox regression analysis was performed to investigate the association of these proteins with the overall survival of MM patients. Increased p16 expression was significantly associated with reduced survival at three years (P=0.039). Increased p53 expression correlates with reduced one-year (P=0.025), and, two-year survival (P=0.037). Increased p53 and p16 protein expression may be helpful prognostic indicators for the management of these patients.
