Background: Carcinogenicity presents as a major challenge to scientists and society.. Cervical cancer ranks fifth in the world and is the second cause of death in developing countries like India and China. The rate of death due to cervical cancer is greatest in India. At any time women are at risk of harboring HPV infection, which has been seen to cause cervical cancer. Clinical judgment should be used in spite of all high quality modalities available for screening and diagnosis, as initiated by WHO (World health organization) the Down Staging of cervical cancer, VIA, VILI, Pap smear introduced by George Papanicolaou in 1940s , HPV testing by Immunocytochemistry (ICC) and  HPV DNA , Colposcopy , are other modalities to screen cervix. The study aims to evaluate the correlation between Pap smear, visual inspection and Immunocytochemistry of Human papilloma virus (HPV).Methods: All 100 consecutive women were subjected to visual inspection of cervix, Pap smear and immunocytochemistry of HPV. Pap smear was done by conventional method.Results: it was seen that out 100 consecutive cervico-vaginal, ears for Pap and Immunocytochemistry, only 33 were abnormal, 24 were ASCUS, 6 were LSIL, 2 were HSIL, 1 was SCC and 67 were NILM out of which 3 were reactive for ICC. And all 33 were reactive for ICC.Conclusions: The p16 immunostaining performed on conventional smears can become alternative or addition to l HPV DNA tests. The Bethesda System (TBS) 2001 for reporting cervical cytology diagnosis is of high value in detecting abnormal cervical cytology. It is further concluded that the ancillary screening for HPV in NILM category seems to be not advisable as percentage of detection of HPV in this category is low.

Cervical cancer (CC) is one of the most common causes of cancer-related deaths worldwide. CC is mainly caused by human papilloma virus (HPV), which can be prevented by vaccination. We conducted a cross-sectional study in secondary occupational health school (SOHS) through a questionnaire aimed to assess the awareness and knowledge regarding HPV infection of students. A total of 2248 students participated in the survey, 45.3% of them had heard about CC, while only 21.9% of them had heard about HPV; and 74.2% had no idea of the causal link between HPV infection and CC. Most participants displayed poor awareness and knowledge about HPV infection. The results suggested that age, grade, major, academic performance, etc. were correlated with higher awareness of CC, HPV and HPV infection (p < 0.05). In multivariable logistic analysis, third-grade students had the most increased awareness of CC (OR = 17.13, 95%CI: [8.11, 36.15]), HPV (OR = 6.59, 95%CI: [4.16, 10.43]) and HPV vaccine (OR = 2.78, 95%CI: [1.78, 4.32]) when compared to first-grade. Awareness and knowledge regarding HPV infection were insufficient among students in SOHS. As the future healthcare providers, these results highlight the need to supplement targeted education to improve their awareness and knowledge of HPV and vaccination.

Abstract Background: Peutz-Jeghers syndrome(PJS) is a very rare autosomal dominant disorder with predisposition to multiple neoplasms. Gastric-type adenocarcinoma (GAS) is a less common carcinoma of the cervix than squamous cell carcinoma, which is more aggressive and has lower 5 year survival rate than usual type endocervical adenocarcinoma (ECA), and unrelated to human papilloma virus(HPV) infection as well. We present a 32 year-old patient with Peutz-Jeghers syndrome who was found to have gastric-type adenocarcinoma of the cervix.Case presentation: A 32-year-old woman without sexual life ever who was diagnosed Peutz-Jeghers syndrome when she was two years old presented with watery discharge for more than 6 months. A tumor around 6cm was found on the cervix and she was diagnosed gastric-type mucinous adenocarcinoma of the cervix clinical stage IB3. She was treated with artery intervention chemotherapy for one course followed by radical surgery and then systematic chemotherapy.Conclusions: The case suggests more thorough cancer screening for patients with PJS as the disorder is rare and has high risk of malignancies. Young patients with Peutz-Jeghers syndrome, including those without sexual life, who have watery discharge or bleeding should be screened for cervical carcinoma even if cytologic results or human papilloma virus (HPV) is negative.

Abstract [Purpose] Tobacco smoking has been reported to influence the prognosis of human papilloma virus (HPV)-related orophageyngeal squamous cell carcinoma (OPSCC). However, it remains to be studied whether tobacco smoking equally affects the patients treated by various modalities. [Material and Method] From 2010 through 2018, 241 patients with OPSCC were treated in a single institution, out of which 144 patients had HPV-related OPSCC. P16 immunohistochemical staining was used as a surrogate of HPV infection. Two patients was excluded because of inadequate radiation dose, and the remaining　142 patients were the subject of this study. Median age was 63.8 years and more than 80% were male. More than 70% were smokers or ex-smokers with a median pack year of 17.3. Eighty-seven patients (61.3%) were classified as stage I.[Results] For all 142 patients with HPV-related OPSCC, overall survival (OS) and disease-specific survival (DSS) were 87.0% and 93.4% in 3 years, respectively. There were no differences of OS and DSS according to the stages by 8th edition of tumor, node, and metastasis (TNM) classification and the primary sites. OS and DSS were different by the amount of tobacco smoking expressed in pack year (PY) > 30 and < 30. Also the presence of secondary cancer impacted OS. However, the influence of the amount of tobacco smoking was reduced in the patients treated by radiation therapy. [Conclusions] The impact of tobacco smoking upon the prognosis of HPV-related OPSCC seems to be dependent upon therapeutic modalities.

The Impact

Abstract Background Human papilloma virus (HPV) is the most common sexually transmitted infection in the United States, with an annual incidence rate of approximately 14 million people. The HPV vaccine has been demonstrated to be highly effective in the prevention of HPV infection and HPV-associated diseases. This study aims to evaluate the impact of HPV vaccine on the prevalence of HPV infection in the United States and evaluate the trends of disease prevalence pre- and post-HPV vaccine implementation. Methods We conducted a secondary data analysis of the National Health and Education Survey (NHANES) for trends in HPV infection from 2003 to 2016. The analysis was grouped into a pre-HPV vaccine implementation (2003–2006) cohort including 4064 females, aged 18–59 years; and a post-HPV vaccine implementation (2007–2016) cohort which included 10718 females, aged 18–59 years. Further analysis of HPV infection prevalence, pre- and post-HPV vaccine implementation, stratified by sociodemographic characteristics were conducted. Results The prevalence of HPV infection prior to HPV vaccine implementation was 43.98% (95 CI 42.71%–46.58%) compared with 40.55% (95 C.I 40.55%–40.56%) in the post-HPV vaccine implementation era. Among females with HPV infections in the post-HPV vaccine implementation cohort 82.6 (95% CI 80.41%–83.42%) were unvaccinated. In both cohorts, black females had a significantly higher prevalence of HPV with a prevalence rate of 18.56% (95% CI 18.23%–20.56%) in the pre-HPV vaccine implementation cohort, and 15.61% (95% CI 14.82 – 19.4%) in the post-HPV vaccine implementation cohort. Females with less than high school education had a higher prevalence of HPV in the pre and post- HPV vaccine implementation cohorts with prevalence rates of 25.77% (95% CI 23.44%–28.72%) and 24.96% (95% CI 23.41%–25.67%), respectively. Conclusion The results suggest that HPV infection prevalence has declined since the implementation of HPV vaccine to US national immunization program. Our findings highlight disparities in HPV infection prevalence by race and educational status, and these patterns are in keeping with HPV-associated disease such as warts and HPV-associated cancers.

Background and objective: Lipocalin 2 (LCN2) has an oncogenic role in promoting tumorigenesis through enhancing tumor cell proliferation and the metastatic potential. The aim of our study was to determine whether serum LCN2 could serve as a diagnostic marker of cervical cancer (CC) and to evaluate the correlation between its serum concentration, the clinical stage of the cancer and Human Papilloma Virus HPV infections in women. Materials and methods: A total of 33 women with histologically proven cervical cancer (CC), 9 women with high- grade cervical intraepithelial neoplasia (HSIL) and 48 healthy women (NILM) were involved in the study. A concentration of LCN2 was assayed with the Magnetic LuminexR Assay multiplex kit. An HPV genotyping kit was used for the detection and differentiation of 15 high-risk (HR) HPV types in the liquid-based cytology medium (LBCM) and the tissue biopsy. Results: The majority (84.8%) of the women were infected by HPV16 in the CC group, and there was no woman with HPV16 in the control group (P < 0.01). Several types of HR HPV were found more often in the LBCM compared to in the tissue biopsy (P = 0.044). HPV16 was more frequently detected in the tissue biopsy than the LBCM (P < 0.05). The LCN2 level was higher in HPV-positive than in HPV-negative women (P = 0.029). The LCN2 concentration was significantly higher in women with stage IV than those with stage I CC (P = 0.021). Conclusions: Many HR HPV types, together with HPV16/18, can colonize the vagina and cervix, but often HPV16 alone penetrates into the tissue and causes CC. The serum LCN2 concentration was found to be associated not only with HR HPV infection, irrespective of the degree of cervical intraepithelial changes, but also with advanced clinical CC stage. LCN2 could be used to identify patients with advanced disease, who require a more aggressive treatment.
