Social determinants influencing cervical cancer diagnosis: an ecological study.

BACKGROUND: Barriers to accessing health care result in advanced cervical cancer. In Sao Paulo, Brazil, the Index of Social Responsibility (ISR) synthesizes the situation of each town concerning wealth, education, and longevity. This study aimed to evaluate in 645 municipalities the relation of the ISR with stage, age, and morphology in cervical cancer diagnosis. METHODS: An ecological study that used data from Sao Paulo, Brazil, from 2010 to 2017. The ISR was identified through government platforms and data on cancer through the Hospital Cancer Registry. The subjects were the 9,095 women aged 30 years or older. The ISR summarizes municipalities into five levels: dynamic (ISR5), unequal (ISR4), equitable (ISR3), in transition (ISR2), and vulnerable (ISR1). It was used the chi2 tests and logistic regression. RESULTS: The proportion of stage 1 increased significantly with ISR level, ranging from 24.9% in ISR1 to 30.0% in ISR5 (p = 0.040). To every increase in ISR level, the chance of a woman being diagnosed in stage I was at least 30% higher. Woman living where ISR2 had a 1.4 times higher chance of being diagnosed in stage 1 than those living in ISR1 (OR 1.40, 95% CI 1.07-1.84). Squamous tumors frequency decreased when ISR level increased (p = 0.117). A higher proportion of women under 50 years were observed when they lived in wealthier cities (ISR4 and ISR5) (42.2% vs. 44.6%, p = 0.016). CONCLUSION: The ISR was a good health indicator for understanding and predicting the social determinants in cervical cancer diagnosis. The proportion of stage I increased significantly in more favorable social conditions.

Prognosis determination of endocervical adenocarcinomas morphologically reclassified as HPV associated or HPV independent.

OBJECTIVE: To evaluate the prognosis of endocervical adenocarcinomas after reclassification according to the morphologic type based on the 2020 World Health Organization Classification. METHODS: A retrospective longitudinal study with cases admitted at the University of Campinas, Brazil, from 2013 to 2020. The sample included 140 cases morphologically reclassified: 100 cases as adenocarcinoma HPV-associated (HPVA), 17 as HPV-independent (HPVI), and 23 non-HPVA/HPVI. Clinic and pathologic variables were evaluated. Analyses were performed by χ2 , Fisher exact, and Mann-Whitney U tests, Kaplan-Meier curves, Log-rank test, and Cox regression. RESULTS: Compared with the HPVA group, advanced stage (FIGO Stage II+) was more frequent in the HPVI group (P = 0.009), which also showed older patients (P = 0.032), and a higher proportion of deaths (P = 0.006). The median overall survival (OS) differed between groups: 73.3 months in HPVA and 42.4 months in HPVI (P = 0.005). At the multivariate analysis, the risk of death was 6.7 (95% confidence interval 1.9-23.0) times higher in patients diagnosed in advanced stages. CONCLUSION: HPVI cases were more frequent in older patients, presenting at more advanced stages and with worse OS. The morphology-based approach of the new WHO classification appears to be prognostically valuable and applicable in lower- and middle-income settings.

Endocervical Margins Status in Excision for Preventing Cervical Cancer According to the Transformation Zone Type.

OBJECTIVE: The aim of this study is to assess the outcomes of 610 excision types I and II in a referral facility as a function of transformation zone (TZ) types. METHODS: This is a retrospective cohort study of women with cervical precursor lesions who underwent loop electrocautery excision procedure from 2017 to 2019 at the University of Campinas. The primary outcome was endocervical margin status, negative or positive. Other variables were excision type (I/II), TZ (1/2/3), age, menopausal status, hormonal contraceptives, smoking, and sexual debut. Tests used were chi-square or Fisher exact, Mann-Whitney, and simple and multiple logistic regression. RESULTS: The most frequent was TZ 1 (62.5%). Excision II was the most frequent: 54.1% in TZ 1, 67.2% in TZ 2, and 82.1% in TZ 3. A negative margin was observed in TZ 1, 76.0% when excision I and 86.4% when excision II ( p = .009); TZ 2, 86.4% when excision I and 88.9% when excision II ( p = .672); and TZ 3, 76.5% when excision I and 78.9% when excision II ( p = .672). Multivariate analysis revealed in TZ 1 a 2.12 (1.23-3.65) higher risk of obtaining a negative margin in excision type II. In TZ 2 and 3, none of the variables predicted the chance of a negative margin. CONCLUSIONS: The endocervical margin was negative in 3 in every 4 women who underwent loop electrocautery excision procedure, regardless of excision type. Age, menopausal status, smoking, and hormonal contraception did not predict margin status.

Cervical Cancer Screening with HPV Testing: Updates on the Recommendation / Rastreamento do câncer do colo de útero com teste de HPV: Atualizações na recomendação

Abstract The present update is a reassessment of the 2018 'Guidelines for HPV-DNA Testing for Cervical Cancer Screening in Brazil' (Zeferino et al.)9, according to the changes observed in new international guidelines and knowledge updates. The most relevant and recent guidelines were assessed. Questions regarding the clinical practice were formulated, and the answers considered the perspective of the public and private sectors of the Brazilian health system. The review addressed risk-based strategies regarding age to start and stop screening, the use of cytology and colposcopy to support management decisions, treatment, follow-up strategies, and screening in specific groups, including vaccinated women. The update aims to improve the prevention of cervical cancer and to reduce overtreatment and the misuse of HPV testing.

Resumo Esta atualização é uma reavaliação das "Recomendações para o uso de testes de DNAHPV no rastreamento do câncer do colo do útero no Brasil" (Zeferino et al., 2018),9 de acordo com as mudanças observadas nas novas recomendações internacionais, além das atualizações no conhecimento. As recomendações mais relevantes e recentes foram avaliadas. Questões referentes à prática clínica foram formuladas, e as respostas consideraram a perspectiva do sistema de saúde brasileiro, tanto público quanto privado. Esta revisão abrange estratégias baseadas em risco sobre idade para início e término de rastreamento, o uso da citologia e colposcopia para apoiar as condutas, tratamento, estratégias de seguimento, e rastreamento em grupos específicos, incluindo mulheres vacinadas. Esta atualização tem o objetivo de melhorar as estratégias de prevenção do câncer do colo de útero e reduzir o supertratamento e o uso incorreto dos testes de HPV.

The value of the endocervical margin status in LEEP: analysis of 610 cases.

PURPOSE: To describe the results of 610 patients who underwent LEEP and evaluate factors related to a negative margin. METHODS: A retrospective study of patients treated by LEEP at a colposcopy referral service in Campinas, Brazil, 2017-2019. Patients were referred to treat high-grade squamous intraepithelial lesion or adenocarcinoma in situ suspected by cytology and colposcopy (screen-and-treat) or by biopsy. Descriptive analysis was performed by frequencies as a function of the status of the margins (negative or positive). Factors associated with margin status were assessed by regression. RESULTS: The endocervical, ectocervical or both margins were negative in 82.4%, 75.7% and 65.9%, respectively. Age, sexual debut, parity, menopause status, smoking and hormonal contraception showed no difference in the proportion of negative margins. Both margins were negative in 66.1% of patients with transformation zone type(TZ) 1, 73.1% of TZ 2, and 54.7% of TZ 3 (p = 0.015). The endocervical negative margin was obtained in 78.0% of patients submitted to excision I (loop 10 mm) and 82.5% to excision II (loop 15 mm) (p = 0.016). Having the sexual debut at 18 years or older or being submitted to an excision type II doubled the chance of negative endocervical margin (1.98;1.04-3.77 and 1.95; 1.18-3.21, respectively). CONCLUSION: The proportion of negative endocervical margin was 78% in excision I and 86% in excision II. Sexual onset and excision type II increased the chance of obtaining a negative endocervical margin.
