ABSTRACT
Abstract Objective To evaluate the performance of the hybrid capture 2 (HC2) high-risk papillomavirus (hrHPV) assay and cytological test in women with previous abnormalities, to detect cervical intraepithelial neoplasia grade 2 or worse (≥ CIN 2). Methods A cytological test and HC2 (Qiagen, Gaithersburg, Maryland, EUA) for hrHPV were conducted in 359 liquid-based (Sure Path, Becton Dickinson, TriPath Imaging, Burlington, NC, USA) samples collected from women from the Vale do Ribeira Region, during July 2013 and September 2015 with previous cytology classified as atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL), atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesions (ASC-H), and atypical glandular cells (AGC). The histopathological examination was conducted in 179 women. The performance evaluations were calculated using the "exact" Clopper-Pearson 95% confidence interval (CI) test by MEDCALC (Medcalc Software Ltd, Ostend, Belgium). Results The ≥ CIN 2 frequency was 11.7% (21/179). The HC2 for hrHPV and repeat cytology to detect ≥ CIN 2 obtained, respectively, a sensitivity of 90.5% (95% CI = 69.6-98.8) and 90.5%, (95%CI = 69.6-98.8), a specificity of 65.8% (95% CI = 57.9-73.2) and 43.7% (95%CI = 35.8-51.8), a positive predictive value of 26.0% (95% CI = 21.4-31.3) and 17.6%, (95%CI = 14.9-20.6), and a negative predictive value of 98.1% (95%CI = 93.3-99.5) and 97.2% (95% CI = 90.1-99.2). Conclusion Hybrid capture 2 for hrHPV improves the performance of the detection of ≥ CIN 2, without compromising sensitivity, and provides a greater safety margin to return to the triennial screening of women undergoing follow-up due to previous abnormalities, without underlying ≥ CIN 2.
RESUMO
Resumo Objetivo Avaliar o desempenho da captura híbrida 2 (CH2) para papilomavírus humano de alto risco (HPVar) e repetição do exame citopatológico em mulheres com anormalidades em citologia anterior, para detectar neoplasia intraepitelial cervical grau 2 ou pior (≥ NIC 2). Métodos Foi realizado exame citopatológico e CH2 para HPVar (Qiagen, Gaithersburg, Maryland, EUA) em 359 amostras em meio líquido (Sure Path, Becton Dickinson, TriPath Imaging, Burlington, NC, USA) coletadas de mulheres da região do Vale do Ribeira, durante julho de 2013 e setembro de 2015 com citologia anterior classificada como células escamosas atípicas de significado indeterminado (ASC-US), lesão intraepitelial de baixo grau (LSIL), células escamosas atípicas, não podendo excluir lesão de alto grau (ASC-H) e células glandulares atípicas (AGC). O exame histopatológico foi realizado em 179 mulheres. As avaliações de desempenho foram calculadas usando o teste de intervalo de confiança (IC) "exato" de Clopper-Pearson de 95% pelo software MEDCALC (Medcalc Software Ltd, Ostend, Bélgica). Resultados A frequência de≥ NIC 2 foi 11,7% (21/179). A CH2 para o HPVar e a citologia de repetição para a detecção ≥ NIC 2 obteve, respectivamente, sensibilidade de 90.5% (IC 95% = 69,6-98,8) e 90,5% (IC 95% = 69,6-98,8), especificidade de 65,8% (IC 95% = 57,9-73,2) e 43,7%, (IC 95% = 35,8-51,8), valor preditivo positivo de 26,0% (IC 95% = 21,4-31,3) e 17,6%, (IC95% = 14,9-20,6), e valor preditivo negativo de 98,1% (IC 95% = 93,3-99,5) e 97,2%, (IC 95% = 90,1-99,2). Conclusão No geral, a CH2 para HPVar aprimora o desempenho para detecção de ≥ NIC 2, sem comprometer a sensibilidade e proporciona maior margem de segurança do retorno ao rastreio trienal de mulheres com anormalidades citológicas prévias, sem≥ NIC 2 subjacente.
