  • Prostatic cancer is the second cause of cancer-related death among men worldwide. The human papilloma viruses (HPVs) are a family of sexually transmitted viruses which have may have roles in the ethiology of inflammation in prostate leading to benign prostatic hyperplasia (BPH) and prostate cancer (PCa). In this study, we evaluated the frequency of different HPV types in prostatic cancer and benign prostatic hyperplasia (BPH) in Kerman province, southeast of Iran, using real-time PCR techniques. The aim of the present research was to clarify any association with prostatic carcinogenesis. Real Time PCR showed that HPV DNA was found in 20% of 200 PCa samples, 80 percent of these with high-risk HPV types, 40% with type-16,18, 30 % type-31,33 and 10% type 54. High risk HPV DNA was detected in only 2% of BPH samples. Values for low risk types were much higher. Our study provided a support for the role of high risk HPV infection in prostatic disease in Iranian patients, and association between presence of HPV DNA and prostate carcinoma. In particular, HPV 16 and18 might have an important role in prostate cancer.

  • To investigate a population-based survey of the prevalence of human papillomavirus (HPV) infection in South Korea, we performed Papanicolaou smears and tests for HPV DNA and anti-HPV antibody detection in 909 sexually active general women (age range; 20-74 years, median 44 years) who were randomly selected residents from S district of Busan City. The presence of DNA of 36 different HPV types was detected by means of a GP 5+/6+ primer-mediated PCR enzyme immunoassay in cervical exfoliated cells, and IgG antibodies against L1 virus-like particles (anti-VLPs) of 5 HPV types 16, 18, 31, 33, and 58 were tested by means of enzyme linked immunoassay. The incidence of cytologic abnormality was 5.2% in Pap smear. The positive rate of HPV DNA was 10.4%, high in young women younger than 35 years old and proportionally increased according to the cytologic grades. The most often found HPV type was HPV 70, followed by HPV 16 and 33, and high-risk HPV types were more frequent in women younger than 35 years old. The most common HPV type in abnormal cytologic smears was HPV 16, followed by HPV 58 and 66. Anti-VLPs was positive in 19.7% and the frequent anti-VLPs type was against HPV 18, followed by HPV 31 and 16. The concordance between the markers for each specific HPV type was noted in 10 women and HPV 16 was the most frequent one. The incidence of multiple HPV infection was 18.9% and that of multiple anti-VLPs antibodies was 31%. Among 103 self-reported virgins, 4.9% had anti-VLP antibodies.

  • Purpose: The study was designed to: (1) investigate the prevalence of high-risk human papillomavirus (HR-HPV) infection and cervical neoplasia; and (2) evaluate clinical performance of visual inspection with acetic acid/ Lugol's iodine (VIA /VILI), Pap smear, high-risk human papillomavirus (HR-HPV) DNA test for detecting cervical intraepithelial neoplasia grade 2 or worse (CIN2+) and (3) explore appropriate screening approach in rural areas of Shandong Province. Materials and Methods: A total of 3,763 eligible women from Yiyuan County in Yimeng mountainous areas of rural Shandong, China, were enrolled and underwent Pap smear, HR-HPV DNA testing by Hybrid Capture 2 (HC2), and VIA /VILI tests. Women positive in any test were referred to colposcopy and biopsy as indicated. Results: The prevalence of HR-HPV infection among all enrolled women was 11.1% and that in healthy women was 9.9%. In total 33 cases of CIN1, 16 cases of CIN2, 6 cases of CIN3 but none of cervical cancer were detected and the crude prevalence of CIN2+ was 0.58%. For detecting CIN2+, the sensitivity of HR-HPV DNA testing, VIA/VILI, Pap smear was 90.9%, 77.3%, 81.8%, respectively. Pap smear had the best specificity of 98.2%, followed by HR-HPV DNA testing with specificity of 89.4%, VIA/VILI had the lowest specificity of 81.2%. Colposcopy referral rate of HR-HPV DNA testing, VIA/VILI, Pap smear was 11.1%, 18.5%, 2.3%, respectively. Conclusions: Our results suggest that HR-HPV DNA testing alone might be appropriate for primary cervical cancer screening in rural low-resource areas of Shandong Province, China.

  • Vulva cancer is rare among all gynecological cancer worldwide, including Thailand, and mainly affects older women. Persistent high risk type infection of human papillomavirus (HPV) is the one important factor for developing cancer. In this study, we focused on HPV DNA investigation and type-specific distribution of HPV in 25 formalin-fixed paraffin-embedded (FFPE) samples collected from Thai women with vulva cancer histologically confirmed by the National Cancer Institute, Thailand, during 2003-2011. HPV DNA detection and genotyping were undertaken with polymerase-chain reaction and enzyme-immunoassay using GP5+/bio6+ consensus specific primers and digoxigenin-labeled specific oligoprobes, respectively. Human ${\beta}$-globin genes was used as the internal control. Our results showed that 44% (11/25) of all vulva cancer samples were HPV-positive. All of them are high risk HPV type infection, detected as single (63.64%, 7/11) and/or double infections (4/11, 36.36%). HPV 16 was the most common type identified in vulva cancer, followed by HPV 35, 33, 18 and 58. In conclusion, this study presented that HPV-16 is observed at the highest frequency in this cancer, similar to cervical cancer, with HPV 18 being less frequent. Although the sample size was small and could not represent overall incidence and prevalence in Thai women, these preliminary data for vulva cancer are of interest since they reinforce the necessity for HPV screening or vaccination in Thailand.

  • To prevent cervical cancer, human papillomavirus (HPV) bivalent and quadrivalent vaccinations are common, but there is a need for a vaccination system based on the high-risk human papillomavirus (HR-HPV) genotype that differs by region. This study aimed to investigate the prevalence of HPV and the distribution of HR-HPV genotypes in 2,014 women who were not vaccinated against HPV. In this study, HPV DNA testing was performed on 2,014 women not vaccinated against HPV and who visited the Busan Obstetrics and Gynecology Department from September 2020 to July 2021. In addition, liquid-based cytology (LBC) test was performed on 493 cases of HR- HPV genotype infection confirmed by HPV DNA test. The prevalence of HPV among women in Busan was positive in 609 (30.2%) out of 2,014 cases. Among the 609 HPV-positive cases, HR-HPV infection accounted for 493 cases (81.0%), which is a high proportion. Of the total 493 HR-HPV infection cases, liquid-based cytology (LBC) was within normal limits (WNL) in 266 cases (54.0%), atypical squamous cells of undetermined significance (ASCUS) in 97 cases (19.7%), low-grade squamous intraepithelial lesion (LGSIL) in 88 cases (17.8%), and high-grade squamous intraepithelial lesion (HGSIL) in 42 cases (8.5%). Single HR-HPV 52 and 16 accounted for the highest and second highest infection rates, respectively. The high infection rate among women aged 18~39 underscores the need for continuous monitoring. In addition, when there were abnormal findings in the cervical epithelium, HPV 52 was the most common, while in the case of HGSIL, HPV 16 was the most common. The HR-HPV genotypes related to cervical cancer should be continuously collected and monitored for use in health policies, including local and national vaccinations.

  • Human papillomavirus (HPV) plays a critical role in the development of cervical carcinoma. This study analyzed the efficiency of multiplex real-time PCR in detecting and identifying HPV genotypes in samples from women who visited a Korean hospital for checkups. Cervical swab specimens were obtained from women who attended a checkup at the Health Improvement Center of Hospital in Dankook University Cheonan, South Korea and were referred for an HPV genotyping test between January and September 2014. A total of 1703 cervical swab specimens were collected consecutively during this period. PCR results were compared with those of the traditional cytological assay for the same population. Among the 1,703 specimens, 19.91% were HPV positive, of which 14.50% indicated a single infection and 5.40% indicated multiple infections. However, cytology identified only 2.52% of positive cases, including 1.23% cases of atypical squamous cells of undetermined significance, 1% of low grade squamous intra-epithelial lesion, and 0.29% of high grade squamous intra-epithelial lesion. The rate of high-risk and low-risk HPV in the abnormal cytology group was 48 and 23, respectively, and 274 and 136 in the normal group, respectively. HPV types 56, 52, 43 were the most prevalent in that order. Our results confirm the efficiency of the HPV DNA assay for the detection of 28 different HPV genotypes with reasonable sensitivity. A screening strategy that comprises the HPV DNA assay and cytology would help overcome the low sensitivity of a cytological diagnosis.

  • Vulva and Vaginal cancers are rare among all gynecological cancers worldwide, including Thailand, and typically affect women in later life. Persistent high risk human papillomavirus (HR-HPV) infection is one of several important causes of cancer development. In this study, we focused on HPV investigation and specific type distribution from Thai women with abnormality lesions and cancers of the vulva and Vaginal. A total of ninety paraffin-embedded samples of vulva and Vaginal abnormalities and cancer cells with histologically confirmed were collected from Thai women, who were diagnosed in 2003-2012 at the National Cancer Institute, Thailand. HPV DNA was detected and genotyped using polymerase chain reaction and enzyme immunoassay with GP5+/bio 6+ consensus specific primers and digoxigenin-labeled specific oligoprobes, respectively. The human ${\beta}$-globin gene was used as an internal control. Overall results represented that HPV frequency was 16/34 (47.1%) and 8/20 (40.0%) samples of vulva with cancer and abnormal cytology lesions, respectively, while, 3/5 (60%) and 16/33 (51.61%) samples of Vaginal cancer and abnormal cytology lesions, respectively, were HPV DNA positive. Single HPV type and multiple HPV type infection could be observed in both type of cancers and abnormal lesion samples in the different histological categorizes. HPV16 was the most frequent type in all cancers and abnormal cytology lesions, whereas HPV 18 was less frequent and could be detected as co-infection with other high risk HPV types. In addition, low risk types such as HPV 6, 11 and 70 could be detected in Vulva cancer and abnormal cytology lesion samples, whereas, all Vaginal cancer samples exhibited only high risk HPV types; HPV 16 and 31. In conclusion, from our results in this study we suggest that women with persistent high risk HPV type infection are at risk of developing vulva and Vaginal cancers and HPV 16 was observed at the highest frequent both of these, similar to the cervical cancer cases. Although the number of samples in this study was limited and might not represent the overall incidence and prevalence in Thai women, but the baseline data are of interest and suggest further study for primary cancer screening and/or developing the efficiency of prophylactic HPV vaccines in Thailand.

  • Purpose: High risk human papillomavirus (HPV) is the main source of cervical cancer, nearly up to 100%. Because there are no affordable data regarding the incidence of HPV in different sites of oral cavity, the purpose of this study is to review the previous article and to find out about the incidence and types of HPV in specific areas of oral cavity. Methods: We examined a total of 106 patients with oral cavity cancer for HPV detection. Available DNA chip (MY-HPV chip kit$^{(R)}$, Mygene Co., Korea) was used for the detection of low risk HPV types (6, 11, 34, 40, 42, 43, 44) and high risk HPV types (16, 18, 31, 33, 35, 39, 45, 51, 52, 54, 56, 58). Patients were previously diagnosed as invasive cancer of oral cavity. Specimen used for HPV detection was extracted from the main mass during resection and were tested for HPV type, performed by a DNA chip method. Results: Histologic results showed that there were squamous cell carcinomas, mucoepidermoid carcinomas, cystadenocarcinomas, leiomyosarcoma and etc. Among HPV positive cancer, 2 patients showed positive for high risk HPV type 16, 3 patients showed positive for low risk HPV type 6 and the other 2 patients were positive for other types of HPV. Of the 7 patients with HPV positive, 4 patients were on the tongue, 3 on the lower gingiva. Conclusion: Most of the HPV positive cancers were on the tongue in our study. Cervical cancer of HPV infection is reported to be increasing in our society and because HPV infection largely spreads by sexual contact, the incidence of oral cancer with HPV infection is greatly assumed to be on the increase, simultaneously. Because the incidence of HPV on specific areas of oral cavity among oral cancer patients is not identified, more studies are ongoing.

  • Background: To estimate the pre-vaccination distribution of human papillomavirus (HPV) types among women from urban Tunis. Materials and Methods: A total of 611 women aged 18-69 years were enrolled in three local gynaecological outpatient departments. All underwent a gynaecological examination with Pap test and dry swab for HPV detection and typing performed by linear array genotyping test (Roche). Cytological examination was conducted on conventional Pap smears. Results: HPV DNA was found in 6.5% of the women; the most frequent HPV types were HPV 16 and HPV 11 at 3.27% and 1.96%, respectively. The second most frequent high risk (HR) HPV type was HPV 58 (0.82%) followed by HPV 18, HPV 31 and HPV 33 found in only 0.33% of women. Single infections with HPV types, targeted by the quadrivalent vaccine (6, 11, 16, and 18), were detected in 3.6 % of the study patients (55% of positive women). HPV infection was found in 3.83% of women with normal cytology and in 47.4% of women with cytological abnormalities. No statistically significant trend in prevalence by age group emerged for any HPV type or for high or low risk types. Conclusions: These data show a relatively low prevalence of HPV infection in women from urban Tunis with a high proportion of HPV16 and HPV58. This should be considered in the upcoming screening programs and vaccination strategy.
