This paper summarises the position of ESGO and EFC on cervical screening based on existing guidelines and opinions of a team of lead experts. HPV test is replacing cytology as this offers greater protection against cervical cancer and allows longer screening intervals. Only a dozen of HPV tests are considered as clinically validated for screening. The lower specificity of HPV test dictates the use of triage tests that can select women for colposcopy. Reflex cytology is currently the only well validated triage test; HPV genotyping and p16 immunostaining may be used in the future, although methylation assays and viral load also look promising. A summary of quality assurance benchmarks is provided, and the importance to audit the screening histories of women who developed cancer is noted as a key objective. HPV-based screening is more cost-effective than cytology or cotesting. HPV-based screening should continue in the post-vaccination era. Only a fraction of the female population is vaccinated, and this varies across countries. A major challenge will be to personalise screening frequency according to vaccination status. Still the most important factor for successful prevention by screening is high population coverage and organised screening. Screening with self-sampling to reach under-screened women is promising.
本文总结了 ESGO 和 EFC 在宫颈癌筛查方面的立场,依据的是现有指南和一组主要专家的意见。HPV 检测正在取代细胞学检查,因为它能提供更好的宫颈癌防护,并允许更长的筛查间隔。只有少数十几个 HPV 检测被认为具有临床验证的筛查能力。HPV 检测的特异性较低,因此需要使用能选择女性进行阴道镜检查的分流检测。目前,仅细胞学分流检测得到充分验证;HPV 基因分型和 p16 免疫染色将来可能会被使用,尽管甲基化检测和病毒载量也很有前景。本文提供了质量保证基准的摘要,并指出审核已患癌症女性的筛查史是一个关键目标。HPV 为基础的筛查比细胞学或联合检测更具成本效益。HPV 为基础的筛查应在疫苗接种后时代继续进行。只有一小部分女性人群接种了疫苗,而且各国之间存在差异。根据疫苗接种状况为个人定制筛查频率将是一个主要挑战。仍然,通过筛查成功预防的最重要因素是高人群覆盖率和有组织的筛查。通过自我采样进行筛查以覆盖未被筛查的女性具有广阔前景。
