Cervical cancer screening outcomes among First Nations and non‐First Nations women in Alberta, Canada

BackgroundCervical cancer disproportionately affects First Nations women in Canada but there is limited information on their participation in organized cervical cancer screening programs. MethodsThis co-led retrospective cohort study linked population-based Alberta Cervical Cancer Screening Program point of care data with First Nations identifiers. This Screening Program database includes cervical cancer screening history, screen test results, colposcopy procedure findings, and pathology results for all women in Alberta. First Nations identifiers were obtained from Alberta Health who steward these data on their behalf. Data were available from 2012 to 2018 for women 25 – 69 years of age who were age eligible to participate in cervical cancer screening. Screening participation and retention rates, and screening outcomes were compared between First Nations and non- First Nations women using descriptive statistics with trends estimated using joinpoint models. ResultsAge standardized screening participation and retention rates of First Nations women were lower than those for the non-First Nations women, with an average difference of 13.9 % lower for participation rates (95 % confidence interval = 12.9–14.8 %; P <.0001) and 7.2 % for retention rates (95 % confidence interval = 2.2 % to 12.72; P = 0.013). First Nations women consistently had higher percentages of high risk (high-grade squamous intraepithelial lesion, atypical glandular cells, atypical squamous cells where HSIL cannot be excluded, Carcinoma in situ) abnormal cytology tests than non-First Nations women. ConclusionIdentifying where inequities were found in cervical cancer screening participation and retention in this study is the first step to reduce the disproportionate burden of cervical cancer for First Nations women in Canada.

Review of triage strategies for atypical squamous cells of undetermined significance among young women.

In the present study we reviewed the existing literature regarding management approaches for ASC-US and highlight their pros and cons. The ASC-US entity emerged from Bethesda classification 2001. We conducted this review using search words ASC-US triage, ASC-US management in young women, triage tests for ASC-US, and ASC-US outcome from the English literature. We included different cervical cancer policies (American, European and for WHO) and research articles published on ASC-US in young women from the year 2001. We searched in Google Scholar, PubMed, MEDLINE (NCBI) library, Embase (Elsevier), Wiley online library as well as Cochrane library. We defined young women as aged 30 years and below. We identified 52 articles which focused on management approaches of ASC-US, seven articles focused on young women aged <30 years. Five of these articles combined ASC-US with low-grade squamous intraepithelial lesions (ASC-US/LSIL) while only two addressed ASC-US as a standalone entity. The limited number of articles restricts the evidence base supporting the adoption of triage strategies. There is yet, no consensus in the literature regarding the management of ASC-US, more so in young women below the age of 30 years. Researchers, however, agree on a few aspects, which include the necessity for applying a conservative strategy for managing ASC-US in young women, avoiding direct referral for colposcopy at the initial detection of ASC-US, and avoiding the use of human papillomavirus (HPV) testing on young women (unless living with HIV). Newer techniques such as HPV E6/E7 messenger RNA (mRNA), and dual staining p16/ki-67, may serve as better triage to identify cases of HPV persistence and integration which may subsequently lead to preinvasive or invasive lesions.

Fine-Needle Aspiration versus the CytoCore® Motorized Rotating Needle Device for Thyroid Nodule Biopsies: A Retrospective Cohort Study

Introduction: Recently, an FDA cleared motorized fine-needle aspiration device (CytoCore®, Praxis Medical) has become available which is designed to reduce sample variability by enabling more consistent sampling due to the rotational drilling action of the device in combination with the standard in and out motion used to access the thyroid nodule with a needle. The rotation of the needle permits the ability to collect a higher quantity of intact cellular material, which is optimal for determining adequacy and, ultimately, for making a diagnosis. The present study compares the diagnostic performance of a motorized fine needle aspiration (FNA) device to a historical cohort of patients biopsied using ultrasound-guided fine needle aspiration (US-FNA). Methods: Data from 120 patients with thyroid nodules biopsied using a motorized FNA device was retrospectively analyzed. Patient demographics, lesion characteristics, number of passes, Bethesda category, and cellularity scores were compared to a historical control cohort of 100 patients who underwent US-FNA. Nondiagnostic and indeterminate samples rates for motorized FNA were separately compared to literature controls. Results: A significantly reduced median number of passes were required with motorized FNA compared to US-FNA (1.48 ± 0.62 vs. 2.64 ± 1.63, p < 0.001). Adequate samples were obtained after the first pass for 58% of biopsies with motorized FNA compared to 11% with US-FNA. The cumulative percentage of adequate samples increased to 98% after two passes for motorized FNA versus 58% for the US-FNA group. The mean cellularity score was also significantly greater for motorized FNA (3.42 ± 0.63 vs. 1.9 ± 0.59; p < 0.001). A determinant diagnosis was possible for a greater number of samples in the motorized FNA group compared to the control group (91.6% vs. 78%; p = 0.05). The motorized FNA also had a lower nondiagnostic rate compared to US-FNA (2.0% vs. 10%) and a lower indeterminate rate compared to published rates associated with the use of FNA (8.3% vs. 20.0%; p = 0.05). Conclusion: The motorized FNA device required less passes to obtain an adequate biopsy than US-FNA. Its use is also associated with obtaining samples with a higher cellularity and lower nondiagnostic and indeterminate sample rates.

Statistically Significant Associations Between HPV33, HPV35, and HPV56 With Anal HSIL in a Population of MSMLWH.

The aim of the study is to determine the prevalence of high-risk human papillomavirus (hrHPV) genotypes in men who have sex with other men and are living with HIV and the factors associated with anal high-grade squamous intraepithelial lesions (HSIL). Anal swabs were collected for hrHPV genotyping from a cross-sectional group (N = 163) of eligible men who have sex with other men and are living with HIV attending a high-resolution anoscopy clinic. Persistent hrHPV infections were studied in a longitudinal subset (n = 37). Association of anal HSIL with specific hrHPV genotype(s) and with HIV-1 suppression was assessed. Pearson's χ2 test with continuity correction or Fisher's exact test was used to determine statistical significance (alpha = 0.05). Overall prevalence of hrHPV anal infections was 93.3% (152/163). Higher numbers of hrHPV genotypes were detected per sample in the HSIL group compared with less than or Low-grade squamous intraepithelial lesion (≤LSIL) group (p < .001). Proportion of participants infected with HPV33 was higher in the HSIL group (66.7%) than in ≤LSIL group (33.3%, p < .001), as was HPV35 (61.1% vs. 38.9%, p = .001) and HPV56 (56.7% vs. 43.3%, p = .022). HPV33 persistence was highly associated with HSIL (100%; 8/8) compared with ≤LSIL (0%; 0/8) (p < .001). Proportion of HIV-1 suppression (<200 cp/mL) was significantly lower among the HSIL group (80%; 48/60) compared with ≤LSIL group (95.1%; 97/102) (p = .006). Statistically significant associations existed between anal HSIL and HPV33, HPV35, and HPV56 infections, with HPV33 persistence, and with the lack of HIV-1 suppression. These findings emphasize the critical need for genotyping assays that differentiate more than just HPV16, HPV18 and a pool of "other" hrHPV genotypes and that have an intended use with anal specimens. Globally, this highest-risk population would benefit from the 9-valent vaccine to prevent infections and reduce anal cancer risk.

Parsing the thyroid cytopathology suspicious for malignancy diagnosis through molecular-derived risk of malignancy and other related parameters: Insights into nodule characteristics and practice patterns.

Thyroid cytopathology cases with suspicious for malignancy (SFM) diagnosis often result in resection. However, molecular testing offers details that may provide additional insights. In this study, the molecular profiles of SFM cases from two institutions that routinely used ThyroSeq v3 (TSV3) were examined. Following institutional review board approval, SFM thyroid cytopathology cases with TSV3 results were retrieved from the databases of two institutions. Molecular information including molecular-derived risk of malignancy (MDROM), cytologic-histologic correlation data, and other related parameters were calculated. Statistical comparisons were made with a p <.05 considered significant. The core data set comprised 114 SFM cases that passed TSV3 quality assurance. All TSV3 results were reported as positive or negative for genomic alterations and all except five cases provided a probability of malignancy estimate. The overall combined baseline MDROM of 75.7% (95% CI, 70.0-81.4) was comparable to the risk of malignancy (74%) published in the Bethesda System. There was a statistically significant difference between the combined MDROMs of resected and unresected cohorts (79.0% vs 58.6%; p=.0153). Interestingly, the MDROMs of the resected cohorts from the two institutions were statistically different (75.0% vs 85.3%; p=.020). Cytologic-histologic correlation revealed malignant outcome in 88.5% of resected cases. Molecular analyses of SFM cases demonstrated higher risk genomic alterations that were associated with histologically overt neoplasms, resulting in increased malignancy outcome compared to baseline. MDROM analysis revealed differences in the cytopathologic practice patterns regarding follicular-patterned neoplasms at the two institutions.

A Deep Learning Model for Cervical Optical Coherence Tomography Image Classification.

Objectives: Optical coherence tomography (OCT) has recently been used in gynecology to detect cervical lesions in vivo and proven more effective than colposcopy in clinical trials. However, most gynecologists are unfamiliar with this new imaging technique, requiring intelligent computer-aided diagnosis approaches to help them interpret cervical OCT images efficiently. This study aims to (1) develop a clinically-usable deep learning (DL)-based classification model of 3D OCT volumes from cervical tissue and (2) validate the DL model's effectiveness in detecting high-risk cervical lesions, including high-grade squamous intraepithelial lesions and cervical cancer. Method: The proposed DL model, designed based on the convolutional neural network architecture, combines a feature pyramid network (FPN) with texture encoding and deep supervision. We extracted, represent, and fused four-scale texture features to improve classification performance on high-risk local lesions. We also designed an auxiliary classification mechanism based on deep supervision to adjust the weight of each scale in FPN adaptively, enabling low-cost training of the whole model. Results: In the binary classification task detecting positive subjects with high-risk cervical lesions, our DL model achieved an 81.55% (95% CI, 72.70-88.51%) F1-score with 82.35% (95% CI, 69.13-91.60%) sensitivity and 81.48% (95% CI, 68.57-90.75%) specificity on the Renmin dataset, outperforming five experienced medical experts. It also achieved an 84.34% (95% CI, 74.71-91.39%) F1-score with 87.50% (95% CI, 73.20-95.81%) sensitivity and 90.59% (95% CI, 82.29-95.85%) specificity on the Huaxi dataset, comparable to the overall level of the best investigator. Moreover, our DL model provides visual diagnostic evidence of histomorphological and texture features learned in OCT images to assist gynecologists in making clinical decisions quickly. Conclusions: Our DL model holds great promise to be used in cervical lesion screening with OCT efficiently and effectively.

Therapeutic effects of focused ultrasound on vulvar squamous intraepithelial lesions in rat

Objective In this study, we established a Sprague-Dawley rat model of vulvar squamous intraepithelial lesions and investigated the impact of focused ultrasound on the expression of hypoxia-inducible factor-1α (HIF-1α), vascular endothelial growth factor (VEGF) and mutant type p53 (mtp53) in the vulvar skin of rats with low-grade squamous intraepithelial lesions (LSIL). Materials and methods The vulvar skin of 60 rats was treated with dimethylbenzanthracene (DMBA) and mechanical irritation three times a week for 14 weeks. Rats with LSIL were randomly allocated into the experimental group or the control group. The experimental group was treated with focused ultrasound, while the control group received sham treatment. Results After 14 weeks treatment of DMBA combined with mechanical irritation, LSIL were observed in 44 (73.33%) rats, and high-grade squamous intraepithelial lesions (HSIL) were observed in 14 (23.33%) rats. 90.91% (20/22) of rats showed normal pathology and 9.09% (2/22) of rats exhibited LSIL in the experimental group at four weeks after focused ultrasound treatment. 22.73% (5/22) of rats exhibited LSIL, 77.27% (17/22) of rats progressed to HSIL in the control group. Compared with the control-group rats, the levels of HIF-1α, VEGF and mtp53 were significantly decreased in experimental-group rats (p < 0.05). Conclusions These results indicate that DMBA combined with mechanical irritation can induce vulvar squamous intraepithelial lesion in SD rats. Focused ultrasound can treat LSIL safely and effectively, prevent the progression of vulvar lesions, and improve the microenvironment of vulvar tissues by decreasing the localized expression of HIF-1α, VEGF, and mtp53 in rats.

Postoperative clearance of high-risk human papillomavirus for patients with high-grade squamous intraepithelial lesion: Conization versus hysterectomy.

To compare the clearance rate of high-risk human papillomavirus (HR-HPV) in patients with high-grade squamous intraepithelial lesion (HSIL) after 2 different treatments (conization vs hysterectomy), and investigate the influencing factors. A retrospective cohort was established in HSIL patients with HR-HPV infection treated with conization or hysterectomy from July 2020 to May 2022. Age matching (1:1) was conducted between conization group and hysterectomy group. Chi-square test and t-test were employed to compare baseline and clinical characteristics between the 2 groups (conization vs hysterectomy). In addition, univariate and multivariate logistic regression analyses were conducted to compare the influencing factors for HR-HPV clearance at 6 months after surgery. The HR-HPV clearance rates at 6 months were 70.6% and 73.8% in conization group and hysterectomy group in the matched groups, respectively (P = .755). Similarly, at 12 months, the clearance rates were 78.6% and 76.5% in the matched groups, respectively (P = .844). Considering different age groups among all patients, the HR-HPV clearance rates were 81.8%, 72.9%, 73.5%, and 53.6% in the 20 to 30-year, 31 to 40-year, 41 to 50-year and 51 to 60-year groups at 6 months, respectively, and the clearance rates were 87.5%, 80.6%, 84.5% and 52.9% at 12 months, respectively. For HSIL, the postoperative HPV clearance rates were similar between the 2 groups (conization vs hysterectomy), conization is enough to resect the lesion and eliminate HPV. In addition, we should pay attention to the postoperative HR-HPV status in the older population of the 2 groups.

Application of Machine Learning Algorithms for Risk Stratification and Efficacy Evaluation in Cervical Cancer Screening Among the ASCUS/LSIL Population: Evidence from the Korean HPV Cohort Study.

We assessed human papillomavirus (HPV) genotype-based risk stratification and the efficacy of cytology testing for cervical cancer screening in patients with atypical squamous cells of undetermined significance (ASCUS)/low-grade squamous intraepithelial lesion (LSIL). Between 2010 and 2021, we monitored 1,237 HPV-positive women with ASCUS/LSIL every 6 months for up to 60 months. HPV infections were categorized as persistent (HPV positivity consistently observed post-enrollment), negative (HPV negativity consistently observed post-enrollment), or non-persistent (neither consistently positive nor negative). HPV genotypes were grouped into high-risk (Hr) groups 1 (types 16, 18, 31, 33, 45, 52, and 58) and 2 (types 35, 39, 51, 56, 59, 66, and 68) and a low-risk group. Hr1 was subdivided into types a) 16 and 18; b) 31, 33, and 45; and c) 52 and 58. Cox regression and machine learning (ML) algorithms were used to analyze progression rates. Among 1,273 participants, 17.6% with persistent HPV infections experienced disease progression versus no progression in the HPV-negative group (p<0.001). Cox analysis revealed the highest hazard ratios (HRs) for Hr1-a (11.6, p<0.001), followed by Hr1-b (9.26, p<0.001) and Hr1-c (7.21, p<0.001). HRs peaked at 12-24 months, with Hr1-a maintaining significance at 24-36 months (10.7, p=0.034). ML analysis identified the final cytology change pattern as the most significant factor, with 14-15 months the optimal time for detecting progression from the first examination. In ASCUS/LSIL cases, follow-up strategies should be based on HPV risk types. Annual follow-up was the most effective monitoring for detecting progression/regression.

Directions for Improving the Laboratory Component in Secondary Prevention of Cervical Cancer

Relevance. Effective responses are required due to the high incidence of cervical cancer (Cc) throughout the World. RT-PCRbased HPV-testing is becoming more prominent in secondary prevention worldwide, replacing cytology. Russian practice still relies on cytology as the primary method mainly because there is a lack of comparative evaluation of the diagnostic characteristics of cytology and HPV-tests. Aim. Evaluation of diagnostic characteristics of laboratory methods and the relevance of extended HPV genotyping for secondary prevention of cervical cancer. Materials &amp; methods. The study included data (liquid cytology, histology, HPV-test results) from a survey of 653 women (M = 33.55 years old, ME = 32.0 years old, IQR: 26-38 years old) infected with 14 HPV types (16, 18, 31, 33, 35, 39, 45, 45, 51, 52, 56, 58, 59, 66, 68), with presence or absence of intraepithelial neoplasia of varying severity. The study analyzed the correlation of cervical cytology - histology, clinical sensitivity for high-grade squamous intraepithelial lesions (HSIL+), the incidence and the role of 14 oncogenic HPV types in the development of cervical intraepithelial pathology, positive predictive value (PPV) and the diagnostic accuracy of the HPV-test. Results. The agreement between cytology and histology is 67.20%. Clinical sensitivity of cytology is 83.78% for HSIL+ and 94.34% for any other than NILM result. The structure of the HPV population varies depending on the degree of neoplasia, with a constant predominance of HPV16. The clinical sensitivity of the laboratory component rises to 99.5% by conducting HPV-test for at least 12 types of virus. HSIL is more commonly associated with viruses of alpha-9 phylogenetic group, than with alpha-7 and alpha-5/6. The positive predictive value for HSIL+ is reduced depending on the HPV type: 16&gt;33&gt;58&gt;35&gt;45&gt;31&gt;18&gt;52&gt;39&gt;59&gt;58&gt;56&gt;68&gt;66. Conclusions. Clinical sensitivity of the HPV-test exceeds that of cytology, so that secondary prevention of cervical cancer can be effectively achieved through HPV testing. The introduction of an extended genotyping provides more complete information about the risk of having HSIL+. The data obtained will form the basis for the development of directions for improving the epidemiological surveillance information subsystem of HPVassociated cervical diseases

Optimization of fine-needle aspiration biopsy of the thyroid nodes in complex diagnostic situations

Purpose of the study. To identify the most informative combinations of small non-coding RNA molecules (miRNA) associated with malignant tumors of the thyroid gland (TG) in patients with nodular formations with an uncertain conclusion based on fine needle aspiration biopsy (FNA) and the absence of gene mutations.Materials and methods. The study included 83 patients with thyroid nodules according to the results of ultrasound examination with an indefinite cytological conclusion based on FAB materials (category III–V according to the Bethesda classification) and the absence of V600E mutations in the BRAF gene, NRAS, HRAS, KRAS genes in the molecular genetic study of the aspirate. Expression activity of miRNA was determined by realtime PCR in aspirate. Using cluster analysis, homogeneous groups of miRNAs associated with malignant thyroid lesions in patients were identified.Results. In the cells of thyroid nodules obtained during FNA, malignant lesions are associated with an increase in the expression activity of miRNA‑146b,–221,–222,–885–5p and a decrease in the expression of miRNA‑455–3p and miRNA‑574–3p. Reciprocal changes in expression activity in pairs miRNA‑146b/miRNA‑574–3p, miRNA‑221/miRNA‑455–3p, miRNA‑222/miRNA‑574–3p, miRNA‑885–5p/miRNA‑574–3p are more informative when differential diagnosis of benign and malignant thyroid formations than assessing the expression of individual miRNAs.Conclusion. With an uncertain cytological conclusion based on the FAB data of thyroid nodules (categories III–V according to the Bethesda classification) and negative results of a molecular genetic study regarding gene mutations, it is recommended to direct further diagnostic search in determining the expression in the aspirate of miRNA‑146b,–221,–222,–885–5p,–455–3p,–574–3p.

Characterization of High-Risk-Other Human Papillomavirus Genotypes in Papanicolaou Tests, High-Grade Squamous Intraepithelial Lesions, and Cervical Cancer.

Background: The objective of this study was to determine the human papillomavirus (HPV) genotypes of high-risk-other HPV Papanicolaou (Pap) tests and of biopsy tissues from patients with high-grade squamous intraepithelial lesion (HGSIL) or cervical cancer. High-risk-other HPV status was determined with the cobas HPV Test (Roche Diagnostics, North America) that identifies 12 high-risk, non-16/18 HPV genotypes. We hypothesized that we would find genotypes of HPV in our population that are not covered by the 9-valent HPV vaccine. Methods: For this retrospective cohort study, we randomly selected 50 high-risk-other HPV Pap test samples from 2018 from our pathology department registries for HPV genotype determination by Roche Linear Array (Roche Diagnostics, North America). Then we randomly selected 76 cervical biopsy samples of HGSIL or cervical cancer with high-risk-other HPV or HPV unknown status from 2016 to 2022 for HPV genotype determination by next-generation sequencing. Results are reported as counts and frequencies. Results: In the 50 high-risk-other HPV Pap test samples, 21 genotypes of HPV were noted; the most common were 53 (n=6), 51 (n=6), and 59 (n=5). In the samples with HGSIL or cervical cancer, 16 HPV genotypes were detected; the most common were 16 (n=26), 58 (n=12), and 33 (n=8). Among the patients with HGSIL or cervical cancer, the 9-valent HPV vaccine provided coverage for all the HPV variants found in 88% of patients, partial coverage in 8% of patients, and no coverage in 4% of patients. Conclusion: The 3 most common HPV genotypes seen in our high-risk-other HPV Pap test samples are not covered by the 9-valent HPV vaccine. For the HGSIL and cancer samples, 88% of the samples had full HPV genotype coverage with the 9-valent HPV vaccine. This study highlights a presence of HPV that will not be protected by vaccination in a high-risk population.

Impact of Low-grade Intraepithelial Lesions with High-risk Human Papillomavirus (Part I)

One of the cervical cancer screening tests that has been prevalent in low- and mid-level income countries has been the cytology test, which uses a system of standardized reports such as the Bethesda. This system allows the detection of anomalies in squamous epithelial cells, including the squamous intraepithelial lesion (SIL), low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), invasive squamous cell carcinoma, and adenocarcinoma. This categorization in two levels (LSIL and HSIL) has allowed to differentiate the carcinogenic potential of the human papillomavirus (HPV). LSIL are described as transient changes associated with an infection caused by HPV and asymptomatic infections with viral vacuolization within a two-year interval with no specific treatment. In case of HSIL, reference is made to its pre-cancer potential. Several factors have an impact in the onset of a LSIL: the presence of HPV (as one of the key etiologic agents) and other risk factors such as hormones, microbiome, first intercourse at early age, multiple sexual partners, other infections, immune status, and tobaco. All that contribute to the transient nature of the infection, or to its persistence, which in turn may promote the development and progression into an HSIL. The persistence of a high-risk HPV infection (HR-HPV) (or more rarely of low-grade too) plays an important role in the development of cervical cancer.

Diagnostic Performance of Thyroid FNA: Experience of Belarusian National Referral Thyroid Cancer Center.

A fine-needle aspiration (FNA) biopsy is a basic procedure to verify the morphology of thyroid nodules. However, significant variations in the diagnostic performance of FNA, as well as fluctuations in the rate of malignancy (ROM) in different categories of the Bethesda System for Reporting Thyroid Cytopathology, have been discovered in many studies. The development and employment of additional molecular tests in daily clinical practice require an understanding of the prevalence and structure of thyroid malignancy in each category of the Bethesda system. Current research is a continuous retrospective cohort study of the results of the examination and treatment of 1652 patients with thyroid tumors who have undergone primary surgery in 2021 at a national referral thyroid cancer center. FNA diagnostic performance was studied by comparing cytological diagnoses with histological outcomes. The authors evaluated ROM in each Bethesda category and identified the tumors representing a diagnostic pitfall. The overall ROM was 72.4%. When considering ROM in each Bethesda category, it was 16.7% in Bethesda I, 10.1% in Bethesda II, 23.0% in Bethesda IV, 74.8% in Bethesda V, 99.4% in Bethesda VI. The false-positive rate was 65.0%, false negative-0.67%. Follicular and oncocytic adenomas, as well as the follicular variant of papillary thyroid cancer, were the most troublesome entities for patients' management. ROM was comparable to the values implied by the Bethesda system. Follicular tumors were the main source of high false-positive rates. This necessitates the refinement of existing tests and the development of new diagnostic tests to overcome the abovementioned problems.

The Effect of Shared Decision-making on Decision Self-efficacy and Decisional Conflict of Women with Low-grade Squamous Intraepithelial Lesion in Cervical Cytology: An Experimental Study

Background: Women often face decisional challenges and hesitation while choosing the appropriate method to follow up on their abnormal results of cervix cytology. Objective: The present study aimed to determine the effect of shared decision-making (SDM) on decision self-efficacy (DSE) and decisional conflict (DC) about follow-up methods among women with abnormal cervix cytology results. Methods: This interventional study was performed on 54 women referred to the subspecialty clinic of gynecologic oncology. The women were assigned into intervention and control groups using a randomized block design with block sizes of 4 and 6 and an allocation ratio of 1:1. The intervention group received counseling based on the SDM and a decision aid (DA) booklet. The data collection tools included the questionnaires of the demographic and obstetrics characteristics, DC, DSE, and Decision Regret. The collected data were analyzed using SPSS24 software, and independent t-tests and ANCOVA were used. Results: After the intervention, the total mean score of the DC in the intervention group was significantly lower than that in the control group [MD: -22.84 with 95% CI: -23.52 to -21.95, (P &lt;0.001)]. The mean score of DSE in the intervention group was significantly higher than that in the control group [MD: 14.56 with 95% CI: 21.47 to 7.65, (P &lt;0.001)]. Conclusion: The present study results indicated that counseling based on the SDM effectively promotes DSE and reduces DC among women with minor abnormal cervical cytology. Therefore, it is recommended that healthcare providers use SDM for women with abnormal cervical cancer screening results.
