Predictors of abnormal cytology among HPV-infected women in remote territories of French Guiana.

BACKGROUND: Cervical cancer prevention using cervical cytology is insufficiently sensitive, a significant proportion of HPV-infected women having normal cytology. The objective of the present study was to try to identify factors associated with abnormal cytology in HPV-infected women living in remote areas of French Guiana. METHODS: A study was conducted in women aged 20-65 years having HPV infections confirmed by HPV DNA detection using the GREINER-BIO-ONE kit. In addition to HPV testing, cytology was performed and classified as normal or abnormal. Demographic and life history variables, and infecting genotypes were compared between the normal and abnormal cytology groups. RESULTS: None of the demographic and life history variables were associated with cytology results. HPV genotype 53 was significantly associated with absence of cytological abnormalities whereas HPV 52, 58, 16 and perhaps 33 and 66 were independently associated with a greater risk of cytological abnormalities. When grouping HPV genotypes in different species, only species 9 (HPV 16, 31, 33, 35, 52, 58, 67) was significantly associated with abnormal cytology AOR = 5.1 (95% CI = 2.3-11.2), P < 0.001. CONCLUSIONS: It was not possible to predict which HPV-infected women will have cytological abnormalities or notfrom anamnesis. In this study HPV 53 seemed more benign than other HPV genotypes. On the contrary, species n°9, containing 5 of the genotypes contained in the nonavalent HPV vaccine, was significantly associated with more cytological abnormalities. HPV testing and vaccination with the nonavalent vaccine should be implemented in these remote parts of French Guiana.

The singular epidemiology of HPV infection among French Guianese women with normal cytology.

BACKGROUND: In French Guiana, cervical cancer is the second most frequent cancer in females. The objective of the present study was to describe the prevalence of HPV infections in women with normal cervical cytology living in the remote villages of French Guiana. METHODS: Before the study, the study team communicated in the remote villages on the importance of screening. All women from the target population were offered to participate. They signed informed consent during inclusion and then had a concomitant HPV-test and cervical smear. Only women with normal cytology and a good quality smear were analyzed. The detection of HPV-DNA was performed using the GREINER-BIO-ONE kit. RESULTS: Overall, 27.2% of women with normal cervical cytology had a positive HPV-test. There was a U-shaped evolution of prevalence with women over 50 years having the highest HPV prevalence, followed by the 20 to 29 years group. The most prevalent HPV genotypes were HPV 53(3.52%), 68(3.33%), 52(2.59%), 31(2.22%) and 16 (1.85%). The proportion of HPV 16 among HPV-infected women was 6.8%. CONCLUSIONS: HPV prevalence in cytologically normal women was very high. The most prevalent genotypes were very different from what is usually described in the world, and notably in South America.

Cervical cancer incidence in French Guiana: South American.

For the first time, the incidence of cervical cancer was estimated in French Guiana, an overseas French Territory of South America. A certified cancer registry collected exhaustive data on cervical cancer between 2003 and 2005. The age-standardized rate of invasive cervical cancer was 30.3 per 100,000 women. Women from rural areas had lesions with a significantly greater extension than women from urban areas. Compared to South American figures, the standardized incidence of cervical cancer seemed relatively high when viewed in comparison with the gross domestic product per capita. The curative orientation of the health system should move from opportunistic screening for cervical cancer to organized screening, with an emphasis on the rural parts of French Guiana.

In modern medicine, prenatal diagnosis can no longer be sufficient by ultrasound examination. The genetic technical progress and its contribution may remain a challenge in isolated sites with the consequences that this implies in perinatal health.
