JCO Glob Oncol 2021 07;7:1206-1208

Division of Gynecologic Oncology, Sylvester Comprehensive Cancer Center, MI.

Purpose: Understanding the distribution of human papilloma virus (HPV) subtypes in limited-resource settings is imperative for cancer prevention strategies in these regions. The objective of our study is to compare the prevalence of cervical HPV genotypes in women across the African diaspora.

Methods: This study was approved by the African Caribbean Consortium (AC3). Six member institutions (Benin, Ethiopia, The Bahamas, Tobago, Curacao, and Jamaica) provided independently collected HPV data. Prevalence comparisons across for each nation were performed followed by an assessment of anticipated 9-valent vaccine coverage. Chi-square or Fisher's exact tests were used with significance at < .05.

Results: One thousand three hundred fifty high-risk (HR) and 584 low-risk (LR) HPV subtypes were identified in the entire cohort. The most common HR HPV subtype was HPV 16 (17.9%) of infections. The distribution of HR and LR subtypes varied by country. The proportion of HR-HPV subtypes covered by the current 9-valent vaccine was lower in African countries compared with the Caribbean countries (47.9% 67.9%; < .01). No significant difference was seen for LR subtypes (8.1% African continent 5.2% Caribbean; = .20). Marked variation in the proportion of infections covered by the 9-valent vaccine persisted in individual countries.

Conclusion: Significant variations in HPV prevalence were identified among African and Afro-Caribbean women. A large number of women in these regions are potentially uncovered by current vaccination formulation, particularly low-risk HPV infections.

Human papillomavirus (HPV) prevalence and associated risk factors in women from Curaçao.

PLoS One 2018 13;13(7):e0199624. Epub 2018 Jul 13.

Department of Pathology, VU University Medical Centre, Amsterdam, the Netherlands.

Background: In the Caribbean region, a notable difference in HPV-prevalence and genotypes distribution between the islands is observed. Recently we found in Curaçao a low incidence of HPV16 and 18 in cervical cancer compared to the standard world population. We aimed to determine HPV-prevalence, HPV-genotype distribution and associated risk-factors in women from Curaçao.

Methods: 5000 women aged 25-65 years were randomly selected from the national Population Register. HPV was detected by means of GP5+/6+PCR EIA and GP 5+/6+amplimers from HPV-positive samples were genotyped with a reverse hybridisation assay. We also collected personal data and data on risk-factors.

Results: 1075 women were enrolled in the study. Overall HPV-prevalence was 19.7%. Most frequent genotypes were HPV16 (2.3%), 35 (2.1%) and 52 (1.8%). Twenty-seven women detected with abnormal cytology (i.e.≥ASC-US) were referred for biopsy. In women with normal cytology (n = 1048), HPV-prevalence was 17.9% and the most common high-risk HPV (hrHPV)-types were HPV35 (2.0%), 18 (1.8%), 16 (1.5%) and 52 (1.5%). The highest HPV-prevalence (32.8%) was found in the age-group: 25-34 (n = 247). HPV positive women started sex at a younger age (p = 0.032).

Conclusions: HPV-prevalence in the overall population is high and HPV16 was the most common genotype followed by 35 and 18. In women with normal cytology HPV35 is the most common genotype followed by HPV18, 52 and 16. The high HPV-prevalence (32.8%) in women of 25-34 years argue for introduction of cervical cancer prevention strategies. HPV-type distribution found in Curaçao should be taken into account when considering the choice for prophylactic vaccination.

Human papillomavirus (HPV) types prevalence in cervical samples of female sex-workers on Curaçao.

Prev Med Rep 2018 Sep 2;11:120-124. Epub 2018 Jun 2.

VU University Medical Centre, Department of Pathology, the Netherlands.

Sex-workers have an increased risk for high-risk HPV(hrHPV) cervical cancer. On Curaçao, legal and illegal prostitution practice is high and the promiscuous lifestyle is common. We aimed to gain insight in HPV-genotype prevalence in cervical scrapes of female sex workers (FSW) and related risk factors in comparison with women not working in the sex industry. Cervical samples were taken from 76 FSW and 228 non-FSW (NFSW) age matched controls in the period between 2013 and 2015. HPV was detected by GP5+/6+ PCR-EIA followed by genotyping via reverse line-blot. HPV prevalence in FSWs was 25.0% and in NFSWs 29.4% ( = 0.14). NFSW had more often untypable HPV-genotypes (HPV-X:5.3% vs 0.0%;  = 0.042). A trend for statistical difference was observed in HPV prevalence between FSWs from Dominican Republic (42.1%) and FSWs from Colombia (19.2%;  = 0.067). Young age was the only risk factor related to HPV prevalence in FSWs. (Mean age FSW 29.2 y ±7.8 and NFSW 33 y ±6.2) Smoking and drugs consumption were significantly higher among FSW. A significant higher number of women with history of any STD was reported by NFSWs. In addition, >90% of FSW had their previous Pap smear <3 years ago, while >35% NFSW never had a previous Pap smear ( < 0.001).

In Conclusion: no significant difference in HPV prevalence is observed between FSW and NFSW. HPV prevalence in FSW was associated with a lower age. During interviews, FSW seemed more aware about prevention strategies, reported less history of STD's and were more updated with cervical cancer screening, compared to NFSWs.

Supravaginal hysterectomy in Curaçao prevalence and impact on screening for cervical cancer.

Prev Med Rep 2017 Dec 8;8:238-241. Epub 2017 Nov 8.

VU University Medical Centre, Department of Gynaecology and Oncology, Amsterdam, The Netherlands.

In Curaçao, hysterectomies are frequently performed. A common reason for this procedure is the high incidence of leiomyomatosis. However in some cases the cervix is conserved. Following supravaginal hysterectomy most women discontinue cervical cancer screening because they think the cervix is not conserved. We aimed to get insight in the proportion of supravaginal hysterectomies and the level of awareness on the necessity to continue with cervical cancer screening in case of retained cervix. In 2014, data from all hysterectomies performed between 2003 and 2013 on Curaçao were collected. Information about: type of hysterectomy (supravaginal or not), age of the patient, reason for a hysterectomy and incidence of cervical cancer post-hysterectomy were obtained from the nationwide pathology database. In addition, 600 hysterectomised volunteers answered a questionnaire in which the awareness of their type of hysterectomy and continuation of screening for cervical cancer after surgery were investigated. In the at-risk population (≥ 15 years old), 6.0 per1000 women (95% CI 5.9-6.2) had a hysterectomy between 2003 and 2013 (n = 692,304). From the performed hysterectomies, 2.9% were supravaginal and no cases of cervical cancer post-hysterectomy were reported. The majority (55.3%) of women were unaware of their cervical status post-hysterectomy. About one-third (34.3%) of these women had their last Pap-smear pre-hysterectomy. Information campaigns are needed to raise awareness in women, to continue cervical-screening after supravaginal hysterectomy.

High prevalence of high-risk HPV genotypes other than 16 and 18 in cervical cancers of Curaçao: implications for choice of prophylactic HPV vaccine.

Sex Transm Infect 2018 06 11;94(4):263-267. Epub 2017 Oct 11.

DDL Diagnostic Laboratory, Rijswijk, the Netherlands.

Background: Curaçao is a Dutch-Caribbean Island located in a high-risk area for cervical cancer.Prior to introduction of a prophylactic human papillomavirus (HPV) vaccine, knowledge of the prevalence of high-risk HPV vaccine genotypes (HPV16, 18, 31, 33, 45, 52 and 58) in cervical (pre)cancer is required.

Objective: To investigate the prevalence of HPV genotypes in invasive cervical cancers (ICC) and cervical intraepithelial neoplasia (CIN) grade 1, 2 and 3 in Curaçao.

Methods: Paraffin-embedded blocks of 104 cervical cancers (89 squamous, 15 adenocarcinoma), 41 CIN3, 39 CIN2 and 40 CIN1 lesions were analysed for the presence of HPV. Sections were stained by H&E for histopathological evaluation, and DNA was extracted using proteinase K. HPV genotypes were detected using Short PCR Fragment (SPF10) PCR DNA enzyme immunoassay and a Line Probe Assay (LiPA25) .

Results: HPV was found in 92 (88.5%) ICC; 87 (94.6%) had a single HPV infection and 86 (93.5%) were high-risk human papillomavirus (hrHPV)-type positive.The three most common HPV types in ICC were 16 (38.5%), 18 (13.5%) and 45 (6.7%), covering 58.7%.HrHPV vaccine genotypes 16, 18, 31, 35, 45, 52 and 58 were responsible for 73.1% of ICC. For precancerous lesions, the HPV attribution was 85.4% for CIN3, 66.7% for CIN2% and 42.5% for CIN1.

Conclusions: Our study, the largest in the Caribbean region in (pre)cancer, shows that the prevalence of HPV-type 16 and 18 in cervical cancer is lower compared with the world population but no differences in prevalence of these two HPV types are seen in precancerous lesions.When considering HPV vaccination in Curaçao, the relatively high contribution of non-HPV 16/18 genotypes in ICC should be taken into account.
