Fulltext Evaluation of PathTezt™, a Liquid-Based Cytology System

Mohd Nafis NS, Mat Zin AA

Asian Pac J Cancer Prev, 2021 Oct 01;22(10):3261-3266.
PMID: 34711003 DOI: 10.31557/APJCP.2021.22.10.3261

Liquid-based preparation (LBP) cytology is commonly used in most laboratories these days due to its convenience and reliable results for the cervical cancer screening program. The PathTezt™ Liquid-based Pap smear is a second-generation LBP, which uses a filter-based concentration technique in processing the sample.
OBJECTIVE: This study was done to evaluate the cellular fixation, morphology, quality of smear in gynae cytology, and diagnostic interpretation of cervical cytological smears produced by the PathTezt liquid-based processor.
MATERIALS AND METHODS: A total of 400 pap smear samples were taken and processed using the PathTezt 2000 processor. The slides were evaluated in terms of sample adequacy, percentage of the circle covered by epithelial cells, cellular distribution, obscuring factors, and cell fixation.
RESULTS: About 95.25% (381) of the samples were satisfactory for the evaluation. In 19 (4.75%) of the samples, epithelial cells covered less than 50% of the circle. A sample with good cellular distribution was seen in 92% of the cases, while 354 (88.5%) samples showed minimal inflammatory background. Almost all the smears (95.75%) had no erythrocytes in the background. All smears showed good quality fixation features toward nuclear, cytoplasm, and microorganisms. The total performance rate was 99%.
CONCLUSION: Although the PathTezt liquid-based processor is still new compared to other first-generation LBP, the smears produced by this method were of high quality and it was cost-effective.

Fulltext Comparative cost-effectiveness of HPV vaccines in the prevention of cervical cancer in Malaysia

OBJECTIVES: Cervical cancer (CC) had the second highest incidence of female cancers in Malaysia in 2003-2006. Prevention is possible by both Pap smear screening and HPV vaccination with either the bivalent vaccine (BV) or the quadrivalent vaccine (QV). In the present study, cost effectiveness options were compared for three programs i.e. screening via Pap smear; modeling of HPV vaccination (QV and BV) and combined strategy (screening plus vaccination). A scenario based sensitivity analysis was conducted using screening population coverages (40-80%) and costs of vaccines (RM 100-200/dose) were calculated.

METHODS: This was an economic burden, cross sectional study in 2006-2009 of respondents interviewed from six public Gynecology-Oncology hospitals. Methods included expert panel discussions to estimate treatment costs of CC, genital warts and vulva/vagina cancers by severity and direct interviews with respondents using costing and SF-36 quality of life questionnaires.

RESULTS: A total of 502 cervical cancer patients participated with a mean age at 53.3±11.2 years and a mean marriage length of 27.7±12.1 years, Malays accounting for 44.2%. Cost/quality adjusted life year (QALY) for Pap smear in the base case was RM 1,215 and RM 1,100 at increased screening coverage. With QV only, in base case it was RM 15,662 and RM 24,203 when the vaccination price was increased. With BV only, the respective figures were RM 1,359,057 and RM 2,530,018. For QV combined strategy cost/QALY in the base case it was RM 4,937, reducing to RM 3,395 in the best case and rising to RM 7,992 in the worst case scenario. With the BV combined strategy, these three cost/QALYs were RM 6,624, RM 4,033 and RM 10,543. Incremental cost-effectiveness ratio (ICER) showed that screening at 70% coverage or higher was highly cost effective at RM 946.74 per QALYs saved but this was preceded by best case combined strategy with QV at RM 515.29 per QALYs saved.

CONCLUSIONS: QV is more cost effective than BV. The QV combined strategy had a higher CE than any method including Pap smear screening at high population coverage.

Health-care providers' perceptions, attitudes towards and recommendation practice of cervical cancer screening

In Libya, cervical cancer is ranked third as the most frequent cancer among women with early diagnosis being shown to reduce morbidity and mortality. Health-care providers can influence women's screening behaviours, and their lack of recommendations for screening can be one of the barriers that affect women's participation in screening programmes. This study aims to assess the health-care provider's perception around cervical cancer screening. In-depth, face-to-face interviews were conducted with 16 health-care providers, from both public and private sectors in Az-Zawiya city, Libya, between February and July of 2014. The interviews were recorded and transcribed, then analysed using thematic analysis. Our findings suggest that health-care providers did not provide sufficient information regarding cervical cancer screening for women who attend health-care facilities. The results highlight the role played by health-care professionals in motivating women to attend cervical cancer screening programs, and the need for health education of health-care providers to offer a precious advice regarding the screening. On the other hand, health-care providers highlighted that implementation of reminding system of cervical cancer screening will support them to improve screening attendance. In addition, health-care providers stressed the necessity for educational and awareness campaigns of cervical cancer screening among Libyan women.
