生存率

如果肛门癌在癌灶较小时发现，且癌细胞尚未扩散，大多数患者都能得到有效治疗并存活多年，而且常常能保持正常的排便功能。随着癌细胞侵入肛门壁深处或扩散到身体其他部位，治愈概率降低。

生存统计数据

为了解生存率，专家研究了许多正在接受肛门癌治疗的患者，然后报告在确诊后 5 年仍存活的人数。

许多人认为肛门癌生存率会按从 1 到 4 的数字分期进行报告。但美国国家癌症研究所（NCI）是按癌症的扩散程度报告生存率。这被称为概括性分期，其类别包括局限性、区域性和远处转移性肛门癌。

分期 5 年生存率
局限性： 癌症仅局限于肛门区域。 85%
区域性： 癌症已扩散至附近组织或淋巴结。 70%
远处转移性： 癌症已扩散至肝脏或肺部等远处器官。 36%
