Background Guidelines recommend annual anal cytology-based squamous cell carcinoma of anus (SCCA) screening for men who have sex with men (MSM) with HIV aged ≥35 years (eligible population). Recommended threshold for high resolution anoscopy (HRA) depends on its availability: low-threshold (any abnormal cytology) if availability is high, and high-threshold (High-Grade Squamous Intraepithelial Lesion (HSIL) on cytology) if availability is low. Methods Retrospective chart review (2018-2022) at academic HIV clinics. We evaluate (i) 5-year uptake of cytology based SCCA screening in eligible population; (ii) estimate HSIL detection rate based on our current low-threshold criteria, and if high-threshold criteria were used for HRA referral. Results Of 432 eligible individuals, only 219 (50.7%) had at least one, and only 113 (26%) had >1 SCCA screening tests in a median followup of 4 years. N=74 (17.1%) of individuals had at least one abnormal anal cytology during follow-up, of which 56 (75.6%) received HRA. Increasing age (≥57 years) and history of smoking negatively correlated with ever receiving screening. Anal cytology (365 tests in 206 individuals) showed: 17.5% ‘unsatisfactory’, and 26.8% with any abnormal cytology (zero with HSIL) triggering HRA referral. Only 34 individuals (7.8% of screening eligible) were ever detected with HSIL. Strictly using high-threshold criterion for HRA referral would have led to no HRA or HSIL detection. Conclusions We noted poor uptake of screening over time, particularly in older age groups. Importantly, anal cytology performed poorly as a triage test for HRA referral: high rates of ‘unsatisfactory’ samples and low sensitivity for detecting HSIL.

在两个学术中心诊所对 HIV 男男性行为者肛门癌筛查计划的五年评估



背景指南建议对 ≥35 岁的男男性行为者 (MSM) 感染 HIV 的男性(符合条件的人群)每年进行一次基于肛门细胞学的肛门鳞状细胞癌 (SCCA) 筛查。高分辨率肛门镜检查 (HRA) 的推荐阈值取决于其可用性:如果可用性高,则为低阈值(任何异常细胞学),如果可用性低,则为高阈值(细胞学检查显示高级别鳞状上皮内病变 (HSIL))。方法 学术 HIV 诊所的回顾性图表回顾 (2018-2022)。我们评估 (i) 符合条件的人群中基于细胞学的 SCCA 筛查的 5 年采用率;(ii) 根据我们当前的低阈值标准估计 HSIL 检出率,以及是否使用高阈值标准进行 HRA 转诊。结果 在 432 名符合条件的个体中,只有 219 名 (50.7%) 至少进行了一次,只有 113 名 (26%) 在中位随访 4 年中进行了 >1 SCCA 筛查测试。N=74 例 (17.1%) 个体在随访期间至少有 1 例肛门细胞学异常,其中 56 例 (75.6%) 接受了 HRA。年龄增长 (≥57 岁) 和吸烟史与曾经接受筛查呈负相关。肛门细胞学检查(206 人中的 365 次测试)显示:17.5% 的患者“不满意”,26.8% 的患者出现任何异常细胞学检查(HSIL 为零)触发 HRA 转诊。只有 34 人 (7.8% 的筛查合格) 被检测到患有 HSIL。严格使用 HRA 转诊的高阈值标准将导致无法检测到 HRA 或 HSIL。结论 我们注意到随着时间的推移,筛查的接受率很低,尤其是在老年人群中。重要的是,肛门细胞学作为 HRA 转诊的分类试验表现不佳:“不满意”样本率高,检测 HSIL 的敏感性低。
