[Use of HPV virologic test for atypical glandular cells in Alsace between 2014 and 2016].

Abstract

OBJECTIVES\nThe new recommendations by the National Institute of Cancer (January 2017), recommend the use of a complementary human papillomavirus (HPV) virologic test during the diagnosis of atypical glandular cells in pap smear. The aim of this study was the performance analysis of the HPV virologic test for the detection of significant histological cervical abnormalities (CIN2 or more) in case of atypical glandular cells before the new recommendations were published.\n\n\nMETHODS\nWe performed a descriptive and retrospective cohort study in Alsace between January 2014 and December 2016. We have included, from the EVE-association data-base, the patients with atypical glandular cells in pap smear.\n\n\nRESULTS\n1074 patients had a pap smear with atypical glandular cells i.e. 0,18% of total pap smear. This study included 152 patients who had a HPV test. We observed 6 cases of CIN2 (3,9%) and 12 cases of CIN3 (7,9%). No in situ adenocarcinoma nor invasive carcinoma were detected. The sensitivity of the HPV test was 88,9% (IC95%\u2009: [0,65\u2009; 0,99]), the specificity 65,9% (IC 95%\u2009: [0,55\u2009; 0,76]), the positive predictive value 34% (IC95%\u2009: [0,21\u2009; 0,49]) and the negative predictive value 96,8% (IC 95%\u2009: [0,89\u2009; 0,99]).\n\n\nCONCLUSION\nThe detection of HPV in atypical glandular cells seems to be powerful with an excellent negative predictive value but, because of moderate sensitivity and due to the risk of histologic lesion progression, the current recommendations should to be applied with care.
