Abstract

Introduction: Anal mucinous adenocarcinoma (AMAC) is an extremely rare form of anal cancer. Our objective was to examine the incidence, management, and prognostic factors of AMAC.

Methods: We analyzed age-adjusted incidence (AAI) rates over time and compared the prognosis of AMAC with anal squamous cell carcinoma (ASCC) and adenocarcinoma (AAC) using propensity score matching and Kaplan-Meier analysis. Patients were classified based on summary stage and treatments to determine cancer-specific survival.

Results: AAI of AMAC fluctuated within a narrow range (0.082-0.237 per million person-years) from 2000 to 2018. AMAC had a slight non-significant trend of worse prognosis than ASCC (p = 0.348) and a better prognosis than AAC (p < 0.01). Females made up a larger proportion of patients diagnosed with the distant disease (p < 0.05) and unmarried (p < 0.05) and somewhat less probably to need surgical removal (p < 0.01) and radiotherapy (p < 0.01). Elderly patients have lower rates of survival (p < 0.05). Localized stage was associated with better prognosis (p < 0.05). Surgery was associated with a tendency toward better survival (p = 0.095).

Conclusions: AMAC exhibits a low incidence yet favorable prognosis compared to typical AAC and slightly worse compared to ASCC. Elderly age is associated with poorer prognosis, while localized stage indicates better prognosis. Surgery demonstrates a trend toward improved survival.

对肛门黏液腺癌患者的发生、管理和预后进行基于人群和倾向得分匹配的调查。

背景：肛门粘液腺癌（AMAC肛门粘液腺癌（AMAC）是一种极为罕见的肛门癌。我们的目的是研究AMAC的发病率、管理和预后因素：我们分析了随时间变化的年龄调整后发病率（AAI），并使用倾向评分匹配（PSM）和卡普兰-梅耶尔分析比较了AMAC与肛门鳞状细胞癌（ASCC）和腺癌（AAC）的预后。根据综合分期和治疗方法对患者进行分类，以确定癌症特异性生存率（CSS）：从2000年到2018年，AMAC的AAI在较窄的范围内波动（每百万人年0.082-0.237）。AMAC比ASCC的预后更差（p=0.348），比AAC的预后更好（p<0.01），趋势略微不显著。在确诊为远处转移的患者中，女性所占比例较大（p<0.05），且未婚（p<0.05），需要手术切除（p<0.01）和放疗（p<0.01）的可能性较小。老年患者、局部分期、远处分期、未手术者的生存率往往较低（均为 p<0.05）。局部分期与较好的预后有关（p<0.05）。手术与较好的生存率相关（p=0.095）：AMAC的发病率一直很低。AMAC与典型的AAC相比预后较好，与ASCC相比预后稍差。女性AMAC患者接受手术切除或放疗的可能性较低。与典型的AAC相比，AMAC的发病率较低，但预后良好，与ASCC相比，AMAC的预后稍差。高龄与较差的预后有关，而局部分期则预示着较好的预后。手术治疗有提高生存率的趋势。

期刊介绍： With the first issue in 2014, the journal ''Onkologie'' has changed its title to ''Oncology Research and Treatment''. By this change, publisher and editor set the scene for the further development of this interdisciplinary journal. The English title makes it clear that the articles are published in English – a logical step for the journal, which is listed in all relevant international databases. For excellent manuscripts, a ''Fast Track'' was introduced: The review is carried out within 2 weeks; after acceptance the papers are published online within 14 days and immediately released as ''Editor’s Choice'' to provide the authors with maximum visibility of their results. Interesting case reports are published in the section ''Novel Insights from Clinical Practice'' which clearly highlights the scientific advances which the report presents.
