“…low and high grade lesions, while in Mexico HPV 33 was more frequently detected in low grade lesions and HPV 58 in high grade lesions [23,24,27,30]. Similar to previous findings a greater contribution of HPV 18 was observed in ADC, ADSCC, and other histologies (such as neuroendocrine tumours) compared to SCC and conversely, HPV 16 proportion was higher in SCC [9,32].…”

“…Similar to other countries in East Asia, HPVs 52 and 58 had a prominent role in China where these types were identified in more than 7% of cases [9,24,25]. HPV 45 was more common in Brazil and Mexico (more than 6% of cases) and HPV33 accounted for more than 5% of cases in Brazil [9,26,27]. Finally, a wide variety of HPV types were observed in India with HPV 33 being slightly more prominent than others [28,29].…”

The addition of HPVs 31/33/45/52/58 to HPV types included in current vaccines could increase the ICC preventable fraction in a range of 12 to 19% across the four countries, accounting the 9-types altogether 90% of ICC cases. Assuming the same degree of efficacy of current vaccines, the implementation of the 9-valent HPV vaccine in Brazil, Mexico, India and China would substantially impact on the reduction of the world cervical cancer burden.

“…The current study suggests that the risk factors for the incidence of cervical cancer include three aspects: behavioral risk factors, biological factors, and genetic predisposition (Guerry et al, 2011;Boccalini et al, 2012;Peralta-Rodriguez et al, 2012).Uyghur women living in southern China's Xinjiang region, and concentrated relatively.

We investigated the distribution of HPV genotypes in Uyghur women in Xinjiang region of China, and behavioral factors which could predispose them to HPV infection. In this cross-sectional study, women aged 15-59 years were recruited by cluster sampling method in Yutian region in 2009. Liquid-based cytology samples were analyzed centrally for HPV genotype with a linear array detector. Univariate and multivariate logistic regression analyses were performed to identify behavioral risk factors for HPV infection. A total of 883 Uyghur women were recruited successfully. The prevalence of high-risk HPV and low-risk HPV were 7.25% and 1.58%, respectively; the most common HPVs were HPV16, 51, 31, 39 and 58. We found that age of first sexual intercourse was a strong predictor for HPV infection (odds ratio of 4.01 for ≤ 15 years versus ≥25). Having sexual partners ≥ 3 was the second predictor (OR 3.69, 95% CI 2.24-7.16). Cleaning the vagina after sex showed an increased risk of HPV infection (OR 2.72; 95% CI 1.98-5.13); Using the condom showed protective factors for HPV infection (OR 0.36; 95%CI0.12-0.53). HPV16, 51, 31, 39 and 58 were the priority types; the age of first sexual intercourse was identified as a major risk factor for HPV infection. Other notable risks were number of sexual partners and cleaning the vagina after sex. Changing these behavioral risk factors could help to reduce the occurrence of cervical cancer in this population.

“…Nonetheless, the use of any HPV vaccines should be based on local epidemiological data to avoid loss of efficiency due to variations in HPV distribution. To this respect, a recent meta-analysis of HPV prevalence that included >8,000 subjects throughout Mexico reported some variations in the HPV prevalence (Peralta-Rodriguez et al, 2012). This data, combined with the one resulting from different research, might have important implications in the design of new HPV screening systems and the development of new HPV vaccines.…”

Background: The aetiological relationship between human papillomavirus (HPV) infection and cervical cancer (CC) is widely accepted. Our goal was to determine the prevalence of HPV types in Mexican women attending at the Mexican Institute for Social Security from different areas of Mexico. Materials and Methods: DNAs from 2,956 cervical samples were subjected to HPV genotyping: 1,020 samples with normal cytology, 931 with low-grade squamous intraepithelial lesions (LGSIL), 481 with high grade HGSIL and 524 CC. Results: Overall HPV prevalence was 67.1%. A total of 40 HPV types were found; HPV16 was detected in 39.4% of the HPV-positive samples followed by HPV18 at 7.5%, HPV31 at 7.1%, HPV59 at 4.9%, and HPV58 at 3.2%. HPV16 presented the highest prevalence both in women with altered or normal cytology and HPV 18 presented a minor prevalence as reported worldwide. The prevalence ratio (PR) was calculated for the HPV types. The analysis of PR showed that HPV16 presents the highest association with CC, HPV 31, -33, -45, -52 and -58 also demonstrating a high association. Conclusions: The most prevalent HPV types in cervical cancer samples were -16, -18, -31, but it is important to note that we obtained a minor prevalence of HPV18 as reported worldwide, and that HPV58 and -52 also were genotypes with an important prevalence in CC samples. Determination of HPV genotypes is very important in order to evaluate the impact of vaccine introduction and future cervical cancer prevention strategies.
