Many genotypes of human papillomaviruses (HPVs) may lead to morphological changes in cells, resulting in various atypical cells, such as multinucleated cells (MNCs) and koilocytes, in the cervix. However, the relationships between the profiles of HPV genotypes and MNCs are not exactly known. Thus, this study comprehensively profiles the HPV genotypes in MNCs using a microdissection method. HPV genotypes and MNCs were detected in 651 cases with an abnormal Pap smear by liquid-based cytology. Specific HPV genotypes were also detected, including HPV16, 34, and 56, which might be associated with MNCs. This result suggests that the high-risk HPV genotypes, such as HPV16 and 56, are associated with the atypical changes in MNC morphology from normal cervical cells. The results also show that MNCs may be a predictor of squamous intraepithelial lesion.

Transfer Method

Immunocytochemistry (ICC) is an important ancillary technique in clinical cytology for not only identifying and characterizing tumor cells but also gaining prognostic or therapeutic information. Although cell blocks are often prepared for immunocytochemical evaluation of body cavity fluid and fine-needle aspiration specimens, they are not suitable for hypocellular samples. Liquid-based cytology can help prepare additional smears from residual cytological specimens. However, since conventional methods are used for nongynecological specimens in most laboratories, ICC is often limited by the number of cytological smears. Cell transfer methods permit to evaluate several immunocytochemical markers in a single cytological smear. Yet, these methods have some limitations; for example, they are time-consuming (about 3–40 h) and medium membranes with their attached cells are occasionally stretched or torn when peeled off the slides. Therefore, in an attempt to solve these problems, we developed a rapid and reliable cell transfer method using a nylon mesh. Our method requires no special equipment or reagent and can significantly reduce the turnaround time, as compared to previous methods.

Liquid Based Cytology

Objective: The cytomorphological criteria of malignant endometrial lesions in cervical samples are less well described than those of cervical lesions. We wished to investigate if there were features in SurePath™ liquid-based cytology samples that would facilitate more accurate differentiation between benign and malignant endometrial cells. Study Design: This was a two-phase study, with a review of all SurePath™ samples reported as endometrial adenocarcinoma (n = 42) evaluating 12 cytological features in the first phase. In phase 2 (test set), all initial cases plus an additional 83 cases were reviewed using these 12 cytological features to predict the outcome. Results: Out of 12 cytological features evaluated in phase 1 (training set), nuclear chromatin pattern, apoptotic bodies and tingible body macrophages were found to be the most significant features determining malignant histological outcome. These 12 cytological features were re-evaluated in phase 2 (n = 125). Of 125 cases, 54 had a benign and 71 had a malignant or premalignant histological outcome, with a positive predictive value of 56.8%. Conclusion: Granular nuclear chromatin, tingible body macrophages and apoptosis in the background are the most significant factors in determining whether endometrial cells present in cervical samples represent malignancy or are benign. Using these features, relatively accurate predictions of endometrial pathology can be made.

Objective: The Obstetrics and Gynecology Hospital of Fudan University (OGHFU) in Shanghai is the largest academic women's hospital in China. Between 2009 and 2014, the use of liquid-based cytology (LBC) significantly increased while gradually adopting the Bethesda System (TBS), and in 2012 local regulations mandated that pathologists replace technicians to sign out Pap tests. Design: A retrospective OGHFU database search documented all Pap test reports between 2009 and 2014 by specimen type, either LBC or conventional Pap smears (CPS), and final reporting category. A total of 1,224,785 Pap reports were analyzed to document variations in Pap test reporting during a period of major change in cervical screening in China. Results: LBC gradually replaced CPS, which declined from over 65% of Pap tests in 2010 to 6.4% in 2014. Of 514,811 Pap reports using the traditional class system, class I (negative) reports accounted for 98.3% of results. With the introduction of TBS reporting, pathologist reviews and substantial replacement of CPS by LBC, the laboratory abnormal Pap test rate increased significantly to almost 5%. Conclusions: Changes in cervical cytology reporting between 2009 and 2014 in China's largest academic women's hospital reflected both increased use of LBC and the introduction of pathologist TBS reporting. Abnormality rates increased significantly and fell within CAP benchmark ranges.
