Abstract
PDF - Background
The International Endocervical Adenocarcinoma Criteria and Classification (IECC) separated endocervical adenocarcinomas into human papillomavirus (HPV) associated (HPVA) and non–HPV-associated (NHPVA) categories by morphology alone. Our primary objective was to assess the accuracy of HPV prediction by the IECC system compared to p16 immunohistochemistry and HPV RNA in-situ hybridization (RISH). Our secondary goal was to directly compare p16 and HPV RISH concordance.
Methods
Cases were classified by IECC and stained for p16 and HPV RISH on tissue microarray, with discordant p16/HPV RISH cases re-stained on whole tissue sections. Remaining discordant cases (p16/HPV, IECC/p16, IECC/HPV discordances) were re-reviewed by the original pathologists (n = 3) and external expert pathologists (n = 2) blinded to the p16 and HPV RISH results. Final IECC diagnosis was assigned upon independent agreement between all reviewers.
Results
One hundred and eleven endocervical adenocarcinomas were classified originally into 94 HPVA and 17 NHPVA cases. p16 and HPV RISH was concordant in 108/111 cases (97%) independent of the IECC. HPV RISH and p16 was concordant with IECC in 103/111 (93%) and 106/111 (95%), respectively. After expert review, concordance improved to 107/111 (96%) for HPV RISH. After review of the eight discordant cases, one remained as HPVA, four were reclassified to NHPVA from HPVA, two were unclassifiable, and one possibly represented a mixed usual and gastric-type adenocarcinoma.
Conclusions
p16 and HPV RISH have excellent concordance in endocervical adenocarcinomas, and IECC can predict HPV status in most cases. Focal apical mitoses and apoptotic debris on original review led to the misclassification of several NHPVA as HPVA. -

Abstract

- BACKGROUND
Endocervical glandular lesions include glandular atypia (GA), endocervical glandular dysplasia (EGD), adenocarcinoma in situ (AIS), and invasive adenocarcinoma (IA). The diagnosis of malignant glandular lesions is occasionally difficult to distinguish from benign mimickers, and the morphologic features of EGD remain unsettled.
METHODS
Immunohistochemical stains for MIB-1, p53 and CEA were performed on 81 cases of paraffin-embedded endocervical glandular lesions including 22 IA, 15 AIS, 15 EGD, 13 GA, 8 microglandular hyperplasia (MGH) and 8 tubal metaplasia (TM).
RESULTS
The MIB-1 labelling index of IA was 59.68%, 69.53% for AIS, 26.60% for EGD, 16.03% for benign. p53 overexpression was noted in 4 (18%) cases of IA, 3 (20%) of AIS, but none of EGD and benign lesions. It was Interesting to note that one case of MGH showed p53 staining in low intensity. Diffuse strong cytoplasmic CEA positivity was present in all of IA and AIS, whereas seven (47%) of 15 EGD and 12 (41%) of 29 benign lesions showed focal cytoplasmic CEA positivity. There were significant differences in MIB-1 and CEA immunostainings among the adenocarcinoma, EGD, and benign glandular lesions. Adenocarcinoma was closely related to p53 overexpression, although occurring in a low percentage of the cases.
CONCLUSION
MIB-1 immunostaining can be useful in differentiating among endocervical adenocarcinoma, endocervical glandular dysplasia and benign glandular lesions. p53 overexpression might be helpful in the diagnosis of adenocarcinoma.
