Abstract

BACKGROUND

The Swedish National Cervical Screening Registry collects and evaluates comprehensive, nationwide health data to optimise organised cervical cancer prevention. Since all cervical cancer specimens are saved in biobanks, population-based data from the specimens should be available for analysis and linkage with other health information.

METHODS

We identified all cervical cancers diagnosed in Sweden during 2002-2011 (4254 confirmed cases) and requested the tissue blocks to retrieve human papillomavirus (HPV) genotype data using general primer PCR with Luminex genotyping and real-time PCR targeting the E6/E7 regions of HPV16/18.

RESULTS

We obtained blocks from 2932/4254 (69%) of cases. Valid HPV genotyping data was retrieved for 2850 cases (97%). The most common type was HPV16 (60%), followed by HPV18 (19%), HPV45 (7%), HPV31 (3%), HPV33 (2%), HPV52 (2%), HPV39 (1%), HPV70 (1%), HPV56 (1%), HPV35 (1%), HPV58 (1%) and HPV59 (1%). Ninety-six percent of all HPV-positive cases had a single infection. Eighty-nine cases were HPV-positive only when testing for the HPV16/18-E6/E7 region.

CONCLUSIONS

We present one of the largest series of HPV-genotyped cervical cancers to date. The systematic collection of cervical cancer HPV genotyping data by the screening registry will facilitate prevention and monitoring of HPV type-specific disease burden.

摘要

背景

瑞典国家宫颈癌筛查登记处收集和评估全面的、全国性的健康数据,以优化有组织的宫颈癌预防。由于所有宫颈癌标本都保存在生物库中,因此应该可以从标本中获得基于人群的数据,并将其与其他健康信息进行关联和分析。

方法

我们确定了 2002-2011 年期间在瑞典诊断的所有宫颈癌(4254 例确诊病例),并要求检索组织块以使用通用引物 PCR 与 Luminex 基因分型和针对 HPV16/18 的 E6/E7 区域的实时 PCR 来获取人乳头瘤病毒(HPV)基因型数据。

结果

我们从 4254 例病例中的 2932 例(69%)获得了组织块。2850 例病例(97%)的 HPV 基因分型数据有效。最常见的类型是 HPV16(60%),其次是 HPV18(19%)、HPV45(7%)、HPV31(3%)、HPV33(2%)、HPV52(2%)、HPV39(1%)、HPV70(1%)、HPV56(1%)、HPV35(1%)、HPV58(1%)和 HPV59(1%)。所有 HPV 阳性病例中,96%为单一感染。在检测 HPV16/18-E6/E7 区域时,有 89 例仅 HPV 阳性。

结论

我们目前展示了迄今为止最大的 HPV 基因分型宫颈癌系列之一。筛查登记处系统地收集宫颈癌 HPV 基因分型数据将有助于预防和监测 HPV 型特异性疾病负担。
