Epidemiological and Cytopathological Profile of Dysplastic Lesions of the Cervix in South-Kivu/Dr Congo

Background: Cervical cancer is one of the most common cancers in women in the world. The recrudescence of dysplastic lesions is increasing, especially in developing countries, because of the absence of screening. The objective of this work is to determine the prevalence of dysplastic lesions of the cervix in women who are sexually active in South Kivu province. Methods: It was a cross-sectional, descriptive and analytical study of 625 women who came for gynecological consultation, all of whom had cervical-uterine Pap smears, during the period from January 1st, 2017 to December 31st, 2018 at Panzi General Referral Hospital (South Kivu, DR Congo). Data analysis was done using Epi Info software version 7. Results: The median age of the respondents was 34 years, 47.0% of them were married, and 59.0% had a low socio-economic level. The majority had first sexual intercourse between the ages of 15 and 20 (67.5%), a number of former sexual partners estimated at 1 - 5 (87.8%), did not use tobacco (97.4%) and did not use contraception (78.1%). Pap smear was normal in 82.88% of cases, inflammatory in 2.4% of cases and with cytologic abnormalities in 14.72% of cases. Rates of dysplastic lesions were significantly higher among women aged ≥35 years (p = 0.0245), brides (p = 0.0183) and nulliparas (p = 0.0042). Multivariate analysis revealed the adjusted OR (95% CI) statistically insignificant (p < 0.05) for the age group, marital status and parity respondents. Conclusion: Cervical cancer remains a real scourge in the world, especially in sub-Saharan Africa, where the diagnosis is often made when the pathology is at its stage almost incurable. Early detection of dysplastic lesions by Pap smear is therefore imperative in the eradication of this pathology.

Epidemiological and Histopathological Aspect of Precancerous and Cancerous Lesions of the Cervix in the Health District of Commune 5 of Bamako, the CHU of Point “G” and the Gabriel TouréUniversity Hospital of Bamako in Mali

Objective: The aim was to take stock of the screening and treatment of precancerous and cancerous lesions of the cervix in the health district of commune V of Bamako, the “G” point and the Gabriel Touré University Hospital in Bamako, Mali. Patients and Methods: This was a descriptive, cross-sectional, analytical study with retrospective and prospective data collection over an 8-year period from January 1, 2010 to December 31, 2017. This was a multi-center study. Results: From January 1, 2010 to December 31, 2017, 42,492 women were screened, representing a frequency of 24.30%. The median age of the women screened was 32 years;25% were under the age of 25. Three-fourth of the women screened was in the 20 - 49 age group. Of the 22,842 women screened, 90.1% of them had a normal col to IVA/IVL. However, 4.1% of cervical positivity had with acetic acid and 5.1% of positivity to Lugol. 0.7% of the women screened clinically had cancerous lesions. Histologically, 96.5% of the women screened had a normal cervix with benign lesions. For pathological histological findings, we noted 2.6% of precancerous lesions and 0.8% of squamous cell carcinomas and 0.1% of adenocarcinoma. Conclusion: Improved screening indicators with IVA/IV reduce the rate of morbidity and mortality from cervical cancer.

Expression Analysis of p53, Ki-67 and bcl-2 in Pre-Malignant Lesions of the Cervix

Objectives: The present study has tried to analyze the individual and combined expression of the three markers—p53, Ki-67 and bel-2-in HPV associated pre-malignant lesions of the cervix. Methods: Thirty-four cases of high-grade lesions, 21 low-grade cases and 18 normal cases were histologically assessed. HPV-DNA presence and the viral types were determined through PCR and RFLP, respectively. Marker expression was performed by immuno-histochemistry.Results: With regards to viral types, HPV with high oncogenic potential represented the majority, with just one case reporting the low oncogenic potential for viral infection (HPV 6). HPV was the most frequent and could be associated with the high-grade lesion group, however, no significant associations were found between the viral ones and the marker expression. When the expression location, beyond the basal layer, was taken into account, the three markers proved to be good indicators of the lesion grade. The markers’ combined expression: p53(-), Ki-67(+), bcl-2(-) and p53(-), Ki-67(+), bcl-2(-) was statistically significant when associated with the lesion grade.Conclusions: The results suggest that the p53, Ki-67 and bel-2 markers can contribute to differentiate the lesion grades, whether in its isolate form or in combined form.

Screening for Precancerous Cervical Lesions in Women of Reproductive Age in the Kara Region of Togo in 2022

Introduction: Worldwide, cervical cancer is the 4th most common cancer in women and is a public health problem. The objective of this study was to estimate the prevalence of precancerous cervical lesions and to describe its associated factors among women of reproductive age in the Kara region of Togo. Methods: A cross-sectional study was conducted from March 6 to 14, 2022 in 11 health centers in Kara. Data were collected using a standardized questionnaire and screening for precancerous cervical lesions was performed by visual inspection of the cervix, after application of 5% acetic acid and Lugol’s. Logistic regression analysis was performed to describe factors associated with precancerous lesions. Results: A total of 728 women with a median age of 36, interquartile range [31 - 41] were enrolled. The prevalence of precancerous cervical lesions was 3.9%, 95% confidence interval (95% CI: [2.6 - 5.4]. Factors associated with the presence of precancerous lesions were age at first sexual intercourse ≥ 18 years (adjusted odds ratio (aOR = 3.67;95% CI [1.17 - 18.4]) and being a sex worker (aOR = 8.14;95% CI [1.96 - 27.1]). HIV infection was not associated with the presence of precancerous lesions. Conclusion: The results of this study underscore the importance of intensifying cervical cancer screening efforts in resource-limited countries for better management. These efforts should prioritize vulnerable populations such as female sex workers.

Practice of Screening for Precancerous Cervical Lesions in Koumpentoum Health District (Senegal)

Introduction: Cervical cancer is preventable through vaccination against papillomaviruses and screening for precancerous lesions. The objective of this study was to determine the frequency of screening practice and to identify associated factors. Methods: This was a cross-sectional descriptive and analytical study. Data were collected from individual interviews during household surveys. Data collection took place from (1st) to (30th) September (2021). The following were explored: socio-demographic characteristics, knowledge, attitudes and practices of women regarding screening. Results: A total of (294) women aged between (18) and (69) years were included. The mean age was (35.79) years (±9.81). The median age was (34) years. The frequency of screening was (16%);that of precancerous lesions was (4.26%). Factors statistically and significantly associated with screening uptake were cervical cancer information (OR = 5.42 (1.27 - 23.16);p = 0.003), knowledge of the availability of screening (ORa = 7.73 (3.01 - 18.51);p - 7.31);p = 0.014). Conclusion: Frequency of pre-cancerous lesions of cervical cancer is high in Koumpentoum health district (4.26%), while the practice of screening is low there (16%). The factors associated with this low performance are related to a lack of adequate knowledge of women about cervical cancer.

宫颈高级别鳞状上皮内病变腺体受累和HPV感染对复发的影响

目的分析腺体受累及人乳头瘤病毒(HPV)持续感染对宫颈高级别鳞状上皮内病变(HSIL)复发的影响,为术后临床管理提供依据。方法收集行宫颈冷刀锥切术治疗的596例HSIL患者临床资料,其中腺体受累240例(腺体受累组)、腺体未受累356例(腺体未受累组)。以术后2年或再次出现HSIL为研究终点,比较复发患者与未复发患者间差异,结合患者腺体受累和HPV-16持续感染情况将患者分为腺体受累伴HPV-16持续感染组、腺体受累不伴HPV-16持续感染组、腺体不受累伴HPV-16持续感染组和腺体不受累不伴HPV-16持续感染组,比较4组间HSIL复发率的差异。结果596例患者中,复发75例(12.6%)。腺体受累组患者的HPV-16感染率高于腺体未受累组(67.9%νs.23.0%,P<0.05)。复发患者的≥45岁者比例、腺体受累和HPV-16持续感染者比例与未复发患者比较差异均无统计学意义(P均>0.05)。腺体受累伴HPV-16持续感染组、腺体受累不伴HPV-16持续感染组、腺体不受累伴HPV-16持续感染组和腺体不受累不伴HPV-16持续感染组的复发率分别为33.8%、10.9%、8.5%和9.7%,腺体受累伴HPV-16持续感染组复发率高于其他3组(P均<0.017)。结论腺体受累同时伴HPV-16持续感染的HSIL患者在宫颈冷刀锥切术后易复发,应对该类患者采用更积极的手术治疗方案并加强随访。
