口腔粘膜原发性恶性黑色素瘤预后因素探讨

Prognostic Factors in Primary Malignant Melanoma of the Oral Mucosa

摘要: 目的　探讨影响口腔粘膜原发性恶性黑色素瘤预后的因素。方法　回顾分析 35例患者的临床及病理资料。结果　全组总的 5年生存率 2 8.6%。其中临床～期与～期分别为45%、6.7% (P<0 .0 1 )。雀斑样型、浅表扩散型与结节型分别为 38.9%、1 4.3% (P<0 .0 1 ), 病变局限于上皮层者与侵及粘膜下层者分别为 50 %、1 9.1 % (P<0 .0 1 )。手术加化疗组 5年生存率 35.7%, 单纯化疗组均于 5年内死亡。结论　口腔粘膜原发性恶性黑色素瘤的预后与临床分期、病理类型、病变侵袭深度及治疗方式有关。
