Ouh YT, Kim HY, Yi KW, Lee NW, Kim HJ, Min KJ. Enhancing Cervical Cancer Screening: Review of p16/Ki-67 Dual Staining as a Promising Triage Strategy. Diagnostics (Basel) 2024; 14:451. [PMID: 38396493 PMCID: PMC10888225 DOI: 10.3390/diagnostics14040451] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 02/16/2024] [Accepted: 02/16/2024] [Indexed: 02/25/2024] Open
Abstract
Cervical cancer, primarily caused by high-risk human papillomavirus (HR-HPV) types 16 and 18, is a major global health concern. Persistent HR-HPV infection can progress from reversible precancerous lesions to invasive cervical cancer, which is driven by the oncogenic activity of human papillomavirus (HPV) genes, particularly E6 and E7. Traditional screening methods, including cytology and HPV testing, have limited sensitivity and specificity. This review explores the application of p16/Ki-67 dual-staining cytology for cervical cancer screening. This advanced immunocytochemical method allows for simultaneously detecting p16 and Ki-67 proteins within cervical epithelial cells, offering a more specific approach for triaging HPV-positive women. Dual staining and traditional methods are compared, demonstrating their high sensitivity and negative predictive value but low specificity. The increased sensitivity of dual staining results in higher detection rates of CIN2+ lesions, which is crucial for preventing cervical cancer progression. However, its low specificity may lead to increased false-positive results and unnecessary biopsies. The implications of integrating dual staining into contemporary screening strategies, particularly considering the evolving landscape of HPV vaccination and changes in HPV genotype prevalence, are also discussed. New guidelines and further research are necessary to elucidate the long-term effects of integrating dual staining into screening protocols.

Cancer Cytopathol 2022; 130:955-963. [PMID: 35852302 DOI: 10.1002/cncy.22628] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2022] [Revised: 06/28/2022] [Accepted: 06/29/2022] [Indexed: 01/04/2023]
Abstract
BACKGROUND Most human papillomavirus (HPV)-positive women recover from infections and do not develop cervical intraepithelial neoplasia (CIN) and cervical cancer. Additional triage approaches are needed to reduce unnecessary colposcopy referrals. The aim of this study is to determine the high-risk HPV prevalence in a hospital-based population and to evaluate the performance of p16/Ki-67 dual-stain test for the triage of high-risk HPV-positive women to detect precursor lesions and cervical cancer compared with the ThinPrep cytologic test (TCT). METHODS In a hospital-based population, 100,801 women were provided with a primary HPV DNA test and only women with high-risk HPV infections were triaged using TCT and p16/Ki-67 dual-stain test. CIN2 or worse (≥CIN2) or CIN3 or worse (≥CIN3) were defined as the clinical end points. RESULTS The p16/Ki-67 dual-stain indicated a statistically significant higher sensitivity (82.8% vs. 66.7%%), specificity (51.6% vs. 44.4%), positive predictive value (33.2% vs. 25.8%), negative predictive value (91.2% vs. 82.1%), and accuracy (58.6% vs. 49.4%) compared with TCT examination within ≥CIN2 cases. Similar patterns were observed for the ≥CIN3 end point. CONCLUSIONS Our study demonstrated that p16/Ki-67 dual-stain test could achieve better performance compared with TCT examination for ≥CIN2 or ≥ CIN3 detection, representing a promising approach as a specific and efficient triage strategy for high-risk HPV-positive women.

Abstract
BACKGROUND The development of efficient strategies for managing high-risk human papillomavirus (HR-HPV)-positive women is a major challenge when human papillomavirus-based primary screening is being performed. The objectives of this study were to evaluate the comparative effectiveness of HR-HPV testing based on self-collection (SC) and HR-HPV testing based on collection by a health professional (HP) and to assess the potential usefulness of HR-HPV testing combined with testing with the biomarkers p16/Ki-67, α-mannosidase, and superoxide dismutase 2 (SOD2). METHODS This was a cross-sectional study of 232 women admitted for colposcopy because of an abnormal Papanicolaou smear. The collected material underwent liquid-based cytology, HR-HPV detection, and immunocytochemical testing (p16/Ki-67, α-mannosidase, and SOD2). The gold standard was the histopathological result; the positive reference was CIN2+. RESULTS The overall accuracy of HR-HPV testing was 76.6%; the results for the SC group (78.1%) and the HP group (75.2%) were similar. The positive predictive values (HP, 76.5%; SC, 80.0%), the negative predictive values (HP, 66.7%; SC, 64.3%), the positive likelihood values (HP, 1.35; SC, 1.36), and the negative likelihood values (HP, 0.21; SC, 0.19) were also similar. p16/Ki-67 showed higher sensitivity than the other 2 biomarkers: 78.1% versus 45.8% for α-mannosidase and 44.5% for SOD2. The specificities of the biomarkers were equivalent: 71.4% for p16/Ki-67, 77.8% for α-mannosidase, and 71.2% for SOD2. In the HP group, accuracy also leaned more heavily toward the final score (using α-mannosidase and SOD2) without statistical significance (80.8% vs 77.9%). The contrast with the SC group yielded the same level of accuracy. CONCLUSIONS SC, when associated with testing with biomarkers, is as accurate as collection by HPs in the detection of women at risk for cervical cancer.

Abstract
Context The use of the CINtec® PLUS Cytology Kit as a complementary method of diagnosis is intended to contribute to a risk assessment of CIN II+ cervical lesions development, thus avoiding unnecessary colposcopy in negative cases. This method has proved to be effective in the follow-up of cervical lesions, although there is need for consistency in the approach of equivocal or negative cytological results, with persistent positive High-Risk Human Papillomavirus (HR-HPV) test. Aims The present study intends to retrospectively evaluate the capacity of the CINtec® to add information to the clinical practice within the screening and follow-up of cervical lesions. Additionally, this study intends to define criteria for CINtec® referral in order to maximize its utilization in the Portuguese context. Materials and Methods For this purpose, 225 cases with CINtec® PLUS Cytology Kit and histology results were used, and data were analysed and compared according to the cytology and HR-HPV molecular test results. Results The data of this study show that CINtec® PLUS Cytology Kit is a valid test for the diagnosis of persistent HPV lesions (p = 0.0005), with excellent sensitivity and reliable values of specificity. Relevant patient groups to apply the kit are in agreement with the manufacturer recommendations: women with ASC-US/LSIL result and NILM cytology with HPV-positive test, essentially over 30 years old. Conclusions Although clinical data and previous cytological information must help guiding, authors considered that CINtec® is a really valid test for the prognosis of persistent HPV infections in the female population.

Abstract
The role of oncogenic strains of human papillomavirus in the development of cervical cancer is currently not in doubt. In cervical cancer screening, a co-testing strategy is used, in which cytology and HPV testing are performed. When performing a cytological examination by liquid-based cytology, it is possible to conduct additional diagnostic studies that can be used to more effectively sort patients in order to optimize the volume of diagnostic and therapeutic measures. The article highlights the possibilities of diagnostic tests based on the assessment of microRNA and mRNA expression, as well as tests based on the analysis of DNA methylation from the cytological material. The introduction of new molecular genetic predictors of the cervical cancer development into clinical practice can increase the effectiveness of currently used screening programs.

Implementation of p16/Ki67 dual stain cytology in a Danish routine screening laboratory: Importance of adequate training and experience. Cancer Med 2020; 9:8235-8242. [PMID: 32894896 PMCID: PMC7643653 DOI: 10.1002/cam4.3399] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 07/16/2020] [Accepted: 07/30/2020] [Indexed: 12/14/2022] Open
Abstract
Background Immunocytochemical staining with p16/Ki67 has been suggested as a promising triage biomarker in cervical cancer screening. As dual staining is a subjective method, proper training may be required to ensure safe implementation in routine laboratories and reduce risk of misclassification. We determined concordance between novice evaluators and an expert, stratified by number of slides reviewed at three reading points. Methods The study was conducted at the Department of Pathology, Randers, Denmark. Women were eligible if they were aged ≥45, had been enrolled in one of two ongoing clinical studies, and had a dual stain slide available. Dual staining was performed using the CINtec plus assay. Slides were randomly selected from three reading points at which novice evaluators had reviewed <30, ~300, and ≥500 dual stain slides respectively. Level of concordance was estimated using Cohen's Kappa, κ. Results Of 600 eligible slides, 50 slides were selected for review as recommended by the manufacturer. Median age was 68 years (range: 58‐74). Overall concordance was good (κ = 0.68, 95% confidence interval [CI]: 0.60‐0.76), with an overall agreement of 84% (95% CI: 70.9%‐92.8%). Concordance improved with increasing number of slides reviewed at a given reading point, from a moderate concordance (κ = 0.47, 95% CI: 0.05‐0.90) after reviewing <30 slides to a good concordance (κ = 0.66, 95% CI: 0.20‐0.88) and a very good concordance (κ = 0.88, 95% CI: 0.66‐1.00) after reviewing ~300 and ≥500 slides, respectively. Conclusions When interpreting dual stain slides from older women, concordance increased slightly as novice evaluators received more training and experience. Although further evaluation is warranted, these findings indicate that a significant amount of training and experience of novice evaluators may be needed to ensure accurate dual stain interpretation in this age group. Future studies should accurately describe training and experience of evaluators to enable a better comparison of concordance and diagnostic accuracy across studies.

Abstract
Background The aim of this study was to investigate STMN1 and MKI67 expression in uterine leiomyosarcoma and their potential roles as biomarkers for diagnosis. Material/Methods The expression of STMN1 and MKI67 mRNA in uterine leiomyosarcoma were investigated in TCGA database. The overall survival (OS) and disease-free survival (DFS) were compared between high and low expression groups. Seventy-two patients who received hysterectomy were included and divided into 4 groups: uterine normal smooth muscle tissue (UNSM=30), uterine leiomyoma (UL=30), uterine cellular leiomyoma (UCL=24), and uterine leiomyosarcoma (ULS=18). The STMN1 and MKI67 protein expression of the 4 groups were examined by immunohistochemistry (IHC) assay. Results The expression level of STMN1 mRNA in cancer tissue was significantly higher than those of normal uterine smooth muscle tissue. The high and low expression of STMN1 and mki67 gene mRNA was not related to the patients’ OS and DFS (P>0.05). The positive rate of STMN1 protein in uterine leiomyosarcoma was 100.00%, which was significantly higher than that of the other 3 groups (χ2=11.72, P=0.008). And the positive rate of KIM67 protein in uterine leiomyosarcoma was 77.78%, which was also significantly higher than that of the other 3 groups (χ2=48.89, P=0.000). The diagnostic sensitivity and specificity were 77.78%, 90.74% for STMN1 combined MKI67 with the positive predictive value and negative predictive value of 73.68% and 92.45%, respectively. Conclusions STMN1 and MKI67 were upregulated in uterine leiomyosarcoma and act as potential biomarkers for uterine leiomyosarcoma diagnosis.

Approaches to triage optimization in HPV primary screening: Extended genotyping and p16/Ki-67 dual-stained cytology-Retrospective insights from ATHENA. Int J Cancer 2019; 146:2599-2607. [PMID: 31490545 PMCID: PMC7078939 DOI: 10.1002/ijc.32669] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2019] [Revised: 07/29/2019] [Accepted: 08/15/2019] [Indexed: 12/13/2022]
Abstract
The objective of our study was to assess the performance of different triage strategies for high‐risk human papillomavirus (hrHPV)‐positive results utilizing either extended genotyping or a p16/Ki‐67 dual‐stained cytology (DS) approach, with or without partial genotyping. A subset of women with hrHPV infections participating in the Addressing the Need for Advanced HPV Diagnostics (ATHENA) study were analyzed to determine the number of cervical intraepithelial neoplasia grade 3 or worse (≥CIN3) cases detected, and the absolute risk for ≥CIN3 of each genotype. A clinical utility table was constructed to compare the impact of different triage strategies. In all, 2,339 women with single‐genotype hrHPV infections were identified. Among these were 171 ≥CIN3 cases. The U.S. Food and Drug Administration (FDA)‐approved algorithm (HPV16/18 positive, or 12‐other hrHPV positive and Pap positive, i.e., ≥ atypical squamous cells of undetermined significance) for primary HPV screening detected 132/171 (77.2%) ≥CIN3 cases and required 964 colposcopies (colposcopies per ≥CIN3 ratio: 7.3). An approach that uses DS instead of cytology in the FDA‐approved algorithm detected 147/171 (86.0%) ≥CIN3 cases, requiring 1,012 colposcopies (ratio: 6.9). Utilizing DS for triage of all hrHPV‐positive women identified 126/171 (73.7%) ≥CIN3 cases, requiring 640 colposcopies (ratio: 5.1). A strategy that detected HPV16/18/31/33/35+ captured 130/171 (76.0%) ≥CIN3 cases, requiring 1,025 colposcopies (ratio: 7.9). Inclusion of additional genotypes resulted in greater disease detection at the expense of higher colposcopy ratios. Substituting cytology with a DS triage approach improved disease detection and the colposcopy detection rate. Further reduction of colposcopy rates can be achieved by using DS without partial genotyping. Extended genotyping strategies can identify a comparable number of cases but requires an increased number of colposcopies. What's new? Among HPV‐positive women, the goal is to maximize the number of CIN3 or greater cases detected while minimizing colposcopies. These authors compared various combinations of genotyping and dual‐stained cytology (DS) as triage strategies. From a pool of 2,339 hrHPV+ women, 171 cases with ≥CIN3 were identified. Only one algorithm they tested boosted sensitivity over the current approach without reducing specificity. This method used DS to triage women who tested positive for 12‐other HPV, and referring HPV16/18+ patients directly to colposcopy. This approach caught 147 of the 171 cases, while reducing the number of colposcopies per case from 7.4 to 6.9.

Abstract
Several specific tests for cervical screening have been developed recently, including p16/Ki67 dual immunostaining for diagnosing high-risk human papillomavirus positive squamous intraepithelial lesion in the cervix. However, manual screening of cells in an entire glass slide is currently a standard clinical procedure for quantification and interpretation of immunocytochemical features of the cells. Here, we developed a microfluidic device containing an electroactive microwell array with barriers (EMAB) for highly efficient single-cell trapping followed by on-chip immunofluorescence analysis with minimum loss of the sample. EMAB utilizes patterned electrodes at the bottom of cell-sized microwells to trap single cells using dielectrophoresis (DEP) and cell-holding structures behind the microwells to stabilize the position of trapped cells even without DEP. Using the device, we evaluated the performance of p16/Ki67 dual immunostaining of HeLa cells on the chip. The device shows 98% cell-trapping efficiency as well as 92% cell-holding efficiency against the fixed HeLa cells, and we successfully demonstrated high-efficiency on-chip immunofluorescence analysis with minimal loss of sample. p16/Ki67 dual immunostaining using EMAB may be useful for complementary tests for cervical screening in confirming the histopathological diagnosis.

Abstract
Interleukin enhancer-binding factor 3 (ILF3) may function as a transcriptional coactivator and has been reported to be involved in tumor proliferation and metastasis; however, its role and clinical value in gastric cancer (GC) remains unclear. To understand the value of ILF3 in GC, a total of 80 matched samples selected from GC tissues and the adjacent mucosa were used to evaluate the expression of ILF3 and its association with clinical characteristics. Furthermore, its biological functions and mechanisms were investigated using SGC-7901 and BGC823 cell lines. Immunohistochemistry demonstrated that the positive expression rates of ILF3 in GC tissue were higher compared with those in adjacent mucosa (P<0.05). Significantly overexpressed ILF3 was detected in BGC823 and SGC7901 cells, and the MTT results demonstrated decreased cell activity after ILF3 expression was inhibited. The proportions of cells in the G0/G1 phase increased, while the number of cells in the G2/M phase decreased, and the expression of the genes associated with proliferation varied following inhibition of ILF3 (P<0.05). Positive expression of ILF3 was associated with a poor prognosis for patients with GC, and was an independent risk factor for GC (P<0.05). In conclusion, ILF3 is involved in the deterioration of GC by promoting proliferation of GC cells, and ILF3 protein detection may assist in the prediction of the prognosis of patients with GC.

Abstract
Cervical cancer is one of the most common gynecological malignancies. In recent years, the implementation of cervical cancer screening has resulted in the effective control of cervical cancer incidence. However, many deficiencies still exist in the current screening techniques and strategies. With advancements in cervical cancer screening research, immunochemical staining to determine cervical cytology has shown a broader application prospect in the early screening for cervical cancer, especially for triage in cervical cancer screening.

J Gynecol Oncol 2018; 30:e17. [PMID: 30740950 PMCID: PMC6393632 DOI: 10.3802/jgo.2019.30.e17] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2018] [Revised: 10/19/2018] [Accepted: 10/23/2018] [Indexed: 12/19/2022] Open
Abstract
Objectives To assess the clinical and cost-effectiveness of human papillomavirus (HPV) primary screening triage with p16/Ki-67 dual stain cytology compared to cytology. Methods We conducted an Excel®-based budget impact model to estimate the preinvasive and invasive cervical cancer cases identified, mortality rate, direct medical costs, quality-adjusted life years (QALYs) and the incremental cost-effectiveness analysis of two strategies from the healthcare payer perspective. The study population is a cohort of women 30–65 years of age presenting for cervical screening. Results HPV primary screening triage with p16/Ki-67 dual stain showed higher sensitivity without losing specificity compared to conventional Pap smear. The improving the screening performance leads to decrease the prevalence of precancerous lesion, annual incidence and mortality of cervical cancer. The incidence of cervical cancer case detected by new algorithm compared with conventional method were 31,607 and 38,927, respectively. In addition, the new algorithm was more effective and more costly (average QALY 24.03, annual cost $13,262,693) than conventional cytology (average QALY 23.98, annual cost $7,713,251). The incremental cost-effective ratio (ICER) per QALY gained was $1,395. The sensitivity analysis showed if the cost of cytology and HPV test increased three times, the ICER would fall to $303/QALY gained and increased to $4,970/QALY gained, respectively. Conclusion Our model results suggest that screening by use of HPV genotyping test as a primary screening test combined with dual stain cytology as the triage of HPV positive women in Thai population 30–65 years old is expected to be more cost-effective than conventional Pap cytology.

Dual staining for p16/Ki67 is a more specific test than cytology for triage of HPV-positive women. Virchows Arch 2018; 473:599-606. [PMID: 30094492 DOI: 10.1007/s00428-018-2432-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Revised: 06/29/2018] [Accepted: 08/01/2018] [Indexed: 12/18/2022]
Abstract
Globally, cervical cancer (CC) screening is moving from cytology-based to HPV screening or a combination of both (co-testing). Most HPV-positive women clear the virus and do not develop relevant disease. Additional triage approaches are needed to reduce unnecessary colposcopy referrals. The p16/Ki67 dual stain cytology test (DSCT) is one of the most promising, but it has not (yet) been included as a recommendation in European guidelines. Previous studies in Spain on this issue are lacking. We studied the performance of p16/Ki67 DSCT for the triage of HPV-positive women in Navarra to detect precursor lesions (PLs) and CC compared to cytology only. We selected 1865 HPV-positive women with p16/Ki67 DSCT results and 304 women with an available biopsy result. Sensitivity, specificity and predictive values of the p16/Ki67 DSCT to detect underlying PLs and CC compared to cytology were calculated, using the biopsy as the gold standard. Cytology and p16/Ki67 DSCT showed similar sensitivity (99.0% vs. 98.0%), but cytology had significantly lower specificity (6.9 vs. 39.1%). Of the CIN2+/HPV+ women, triage using cytology only would have resulted in 40.2% true PLs and CC, while using p16/Ki67 DSCT this was 98.0% qualifying the women for colposcopy referral. Our results show that p16/Ki67 DSCT detects more than twice as many true PLs and CC than cytology only in this population. Thus, this test can be considered as an important additional tool in HPV testing-based screening strategies, to avoid unnecessary colposcopy referrals and to reduce health care costs.
