摘要 目的探讨恶性黑色素瘤(MM)患者临床特点,分析影响预后的相关因素。方法回顾性分析313例MM患者的临床随访资料,选择22个对预后可能产生影响的因素采用Log-rank检验进行单因素分析及组间比较,对单因素分析有统计学意义的影响因素进行Cox回归模型多因素分析。建立预后指数(PI)方程,根据PI值将全部患者分为不同危险组,采用Log-rank检验进行相关分析。结果单因素分析结果显示,性别、肿瘤厚度、破溃、大体类型、发病至就诊时间间隔、肿瘤部位、就诊时淋巴结情况、病因、误诊、分期、是否手术、手术方式、手术范围、淋巴结清扫与否、清扫的淋巴结数目、化疗疗程、放疗、化疗与免疫联合治疗可以影响MM患者的预后(P均<0.05)。Cox回归模型多因素分析结果显示,影响MM患者长期生存的独立预后因素为性别、肿瘤厚度、破溃、发病至就诊时间间隔、病因、误诊、分期、手术范围、化疗疗程(P均<0.05)。根据PI值将患者分为预后好、一般、差和极差4个亚组4,个亚组的生存率之间差异均有统计学意义(P均<0.01)。结论性别、肿瘤厚度、破溃、发病至就诊时间间隔、病因、误诊、分期、手术范围、化疗疗程是影响MM患者生存的独立预后因素,PI值可用于预测MM患者的预后,为临床进行个体化治疗提供参考。
