Abstract

CONTEXT

  • Persistent infection with high-risk human papillomavirus (hrHPV) is the major cause of cervical cancer. The effect of HPV infection patterns on cytologic detection of cervical lesions is unknown.

OBJECTIVE

  • To determine the effect of HPV infection patterns on the sensitivity of cytologic detection of high-grade cervical lesions.

DESIGN

  • Papanicolaou tests from 257 women with biopsy-confirmed, high-grade squamous intraepithelial lesions were analyzed with respect to HPV infection patterns.

RESULTS

  • Among 257 biopsy-confirmed, high-grade squamous intraepithelial lesion cases, the preceding cytology showed 20 cases (8%) were benign; 166 cases (65%) were low-grade cervical lesions, including atypical squamous cell of undetermined significance and low-grade squamous intraepithelial lesions; and 71 cases (28%) were high-grade cervical lesions, including atypical squamous cells cannot rule out high-grade squamous intraepithelial lesion (atypical squamous cell-high), atypical glandular cells, and high-grade squamous intraepithelial lesions. In 236 cases tested for HPV, those exhibiting low-grade cervical lesions on cytology were often associated with coinfections of mixed hrHPV genotypes (31 of 40; 78%) or non-16/18 hrHPV (75/103; 73%), compared with single-genotype infections of HPV-16 (33 of 62; 53%) or HPV-18 (2 of 6; 33%) ( P = .001). In contrast, high-grade cervical lesion cytomorphology tended to associate with the single-genotype infection of HPV-16 (20 of 62; 32%) or HPV-18 (3 of 6; 50%), compared with non-16/18 hrHPV (25 of 103; 24%) or multigenotype infection (8 of 40; 20%) ( P = .01).

CONCLUSIONS

  • Our findings suggest that multigenotypic or non-16/18 hrHPV infections often produce deceptive lower-grade cytomorphology, which could result in underdiagnosis and delay of treatment. The HPV infection patterns may offer unrecognized benefit beyond HPV genotyping and should be considered during clinical risk evaluation of women with lower-grade cytology.
摘要

背景

高危型人乳头瘤病毒(HPV)持续感染是宫颈癌的主要病因。HPV 感染模式对宫颈病变细胞学检测的影响尚不清楚。

目的

确定 HPV 感染模式对高级别宫颈病变细胞学检测敏感性的影响。

设计

对 257 例经活检证实为高级别鳞状上皮内病变的患者的巴氏涂片进行分析,研究 HPV 感染模式。

结果

在 257 例经活检证实的高级别鳞状上皮内病变病例中,细胞学检查发现 20 例(8%)为良性;166 例(65%)为低级别宫颈病变,包括非典型鳞状细胞意义不明确和低级别鳞状上皮内病变;71 例(28%)为高级别宫颈病变,包括非典型鳞状细胞不能排除高级别鳞状上皮内病变(非典型鳞状细胞-高)、非典型腺细胞和高级别鳞状上皮内病变。在 236 例 HPV 检测阳性的病例中,细胞学表现为低级别宫颈病变的患者常伴有混合高危型 HPV 基因型(31/40;78%)或非 16/18 高危型 HPV(75/103;73%)感染,而非 HPV-16(33/62;53%)或 HPV-18(2/6;33%)单基因型感染(P=0.001)。相比之下,高级别宫颈病变细胞学形态更倾向于与 HPV-16(20/62;32%)或 HPV-18(3/6;50%)的单基因型感染相关,而非非 16/18 高危型 HPV(25/103;24%)或多基因型感染(8/40;20%)(P=0.01)。

结论

本研究结果提示,多基因型或非 16/18 高危型 HPV 感染常产生具有欺骗性的低级别细胞学形态,可能导致漏诊和治疗延误。HPV 感染模式可能提供 HPV 基因分型以外未被认识的益处,在对低级别细胞学检查的女性进行临床风险评估时应加以考虑。
