INTRODUCTION
Anal adenocarcinoma is a rare malignancy with a poor prognosis.
METHODS
We present a case of rare anal adenocarcinoma in a patient with normal screening colonoscopy. Using the Surveillance, Epidemiology and End Result database between 2000 and 2016, we performed survival analysis among individuals>20 years old comparing anal and rectal cancers.
RESULTS
Survival analysis showed that anal adenocarcinoma is associated with worse outcomes compared with rectal adenocarcinoma and anal squamous cell carcinoma.
DISCUSSION
This case and survival data illustrate the importance of prompt investigation of symptoms irrespective of colorectal cancer screening status with careful attention to examination of the anal area.
简介
肛门腺癌是一种罕见的恶性肿瘤，预后不良。
方法
我们报告了一例罕见的肛门腺癌病例，患者的结肠镜筛查结果正常。利用 2000 年至 2016 年的监测、流行病学和最终结果数据库，我们对 20 岁以上人群进行了生存分析，比较了肛门癌和直肠癌。
结果
生存分析表明，肛门腺癌与直肠癌和肛门鳞状细胞癌相比，预后更差。
讨论
本病例和生存数据表明，无论结直肠癌筛查状况如何，出现症状时都应及时进行调查，仔细注意肛门区域的检查。
