Background: Cervical cancer is the fourth most frequent cancer in women globally, next to breast, colorectal and lung cancer and it is also the fourth most common cause of cancer death in women. According to the Indian council of medical research (ICMR), in India one woman dies of cervical cancer every 9 minutes. This study used PAP smear and histopathology to find out about the epidemiology of pre invasive and invasive lesions of the cervix at tertiary health centre in Punjab and their correlation with various social and demographic features.Methods: This prospective clinical study was carried out in the Department of Obstetrics and Gynaecology in Amritsar Medical College from May 2018 to April 2020, after taking approval from the Institutional Ethical Committee. The study selected 500 women randomly among the patients attending the Gynaecology OPD who met the inclusion criteria. Detailed history and PAP smear was taken at first visit followed by cervical biopsy amongst women with abnormal cytology report or with frank lesions of cervix.Results: Out of 500 women included in the study, majority of women (82.5%) were Negative for intraepithelial lesion or malignancy (NILM), 4% women had Atypical squamous cells of undetermined significance (ASCUS), 6.1% had low grade squamous intraepithelial lesion (LSIL) and 16 (3.2%) had High grade squamous intraepithelial lesion (HSIL). Amongst the histopathology reporting 15.62% patients had cervical intraepithelial neoplasia 1 (CIN I), 6.25% patients had cervical intraepithelial neoplasia II (CIN II), 3.12% patients had cervical intraepithelial neoplasia III (CIN III), 6.3% patients had squamous cell carcinoma and 3.1% patient had adenocarcinoma of cervix. Age, low level of education, poor socioeconomic status, early marriage and multiparity are the risk factors found to be associated with pre invasive and invasive lesions of the cervix. (p<0.001).Conclusions: Though infection with human papilloma virus (HPV) is essential for the development of the disease, there are other high-risk factors like age, poor education, low socioeconomic status, early age at marriage and high parity which are significantly associated with the occurrence of the disease. Therefore, our primary and secondary preventive measures must include the women who come under these high-risk categories.

The study involved 500 patients with LSIL (low grade squamous intraepithelial lesion), HSIL (high grade squamous intraepithelial lesion), stage I-IV cervical cancer, infected with human papillomavirus (HPV), as well as 235 women without pathological changes in cervical mucosa. The comprehensive survey included colposcopy, cytological and histological analysis, detection and genotyping of high-risk human papillomavirus. Viral load and physical status of HPV16 DNA was evaluated in cases of mono-infection (n = 148). The prevalence of virus-positive cases among the patients with LSIL/NSIL, cervical cancer patients and healthy women was 69.2%, 76.7% and 51.9%, respectively. An association between the severity of disease and high viral load was revealed. The frequency of integrated DNA was strongly increased in patients with a high viral load. The frequency of episomal forms was either reduced or not detecteable in patients with high viral load as compared to patients with low viral load. It is reasonable to suggest that a high HPV16 viral load may cause an increase in the frequency of integration of virus DNA into the cellular/host genome. This suggests that a high HPV16 viral load may be considered as a risk factor for prognosis of cervical intraepithelial neoplasia and cervical cancer.

High-risk human papillomavirus (hrHPV) persistent infection is the major cause of cervical cancer. Clinical intervention of hrHPV-associated high-grade squamous intraepithelial lesion (HSIL) is critical to prevent cervical cancer, and current treatment is surgery (an invasive therapy). However, some patients refuse to do so for an afraid of potential adverse effects on future fertility or other concerns which creates a critical need for development of non-invasive therapeutic strategies. Here, we report for the first time the cases of non-invasive intervention with REBACIN®, a proprietary antiviral biologics, in clinical treatment of HSIL. From 12,958 visiting patients assessed for eligibility, 18 HSIL-patients with cervical intraepithelial neoplasia-grade 2, positive of both diffused overexpression of p16 and high-risk HPV were enrolled in this non-invasive clinical intervention mainly due to concerns of future fertility. REBACIN® was administered intravaginally every other day for 3 months (one-course) except during menstrual period, and were followed up for 6-36 months for the examination of high-risk HPV DNA, cervical cytology, and histopathology. After one to three course treatments, most cases (16/18) displayed both the regression from HSIL (CIN2) to normal cervical cytology and clearance of high-risk HPV infection. Further studies demonstrated REBACIN® significantly suppressed HPV16 E7 oncoprotein expression in a human cervical cancer cell line, which is consistent with previous finding that REBACIN® inhibits the growth of tumors induced by expression of E6/E7 oncogenes of either HPV16 or HPV18. This report indicates REBACIN® as a novel effective non-invasive clinical intervention for HSIL-patients as well for high-risk HPV persistent infection, providing a new clinical option for the non-invasive treatment of hrHPV-associated high-grade squamous intraepithelial lesion, which is worthy of further research on clinical validation and application.

Kanker serviks merupakan keganasan pada serviks. Jenis kanker tersebut terjadi pada perempuan dan masih menjadi masalah di Indonesia. Indonesia merupakan negara urutan ke 4 di Asia Tenggara dengan insiden kanker serviks terbesar setelah Kamboja, Myanmar dan Thailand. Berdasar data statistik tahun 2012, tingkat insidensi (incidence rate) kanker serviks di Indonesia 17 per 100.000 perempuan per tahun.(1) Telah terbukti bahwa penyebab primer terjadinya kanker serviks yaitu virus papilloma atau yang lebih dikenal dengan istilah “human papillomavirus (HPV)”. Terdapat beberapa jenis serotype HPV, tetapi tidak semua jenis serotype bersifat progesif menjadikan kanker serviks. Salah satu serotype yang bersifat progesif menjadikan kanker serviks yaitu HPV serotype 16. HPV serotype 16 mampu mengubah sel epitel squamosa serviks (cervical-squamous-epithelial cells=CSEC) normal menjadi lesi intraepitelial squamosa tingkat rendah (low-grade squamous intraepithelial lesion=LSIL) atau neoplasia intraepitel serviks (cervical intraepithelial neoplasia=CIN) 1. Selanjutnya, LSIL atau CIN 1 berkembang menjadi lesi intraepitelial squamosa tingkat tinggi (high-grade squamous intraepithelial lesion=HSIL) atau CIN 2, dan akhirnya menjadi kanker serviks yang invasif (invasive cervical cancer=CIN3).(2)

We performed a case-control association study to evaluate the association between common polymorphisms in MTHFR (C677T and A1298C) and the Arg72Pro polymorphism in the p53 gene and the risk for cervical intraepithelial neoplasia (CIN) or invasive cervical cancer (ICC) in Mexican HPV-infected women. We included 131 women with diagnosis of CIN grade I-II and 78 with CIN III or ICC; as controls we also included 274 women with normal Pap smear and negative HPV test. Genotyping for MTHFR and p53 polymorphisms was performed by PCR-RFPLs. HPV was tested by Hybrid Capture II. Odds ratios and 95% confidence intervals were estimated. Genotype frequencies for the 3 studied polymorphisms were distributed according to the Hardy-Weinberg equilibrium. The A1298C-MTHFR polymorphism showed significant differences for the heterozygous AC genotype and the C allele, whereas the AA genotype and A allele resulted to be genetic risk factors for CIN or ICC (p<0.03). The Arg72Pro-p53 polymorphism showed for the genotypes Arg/Pro and Pro/Pro, and for the Pro allele, a significant association only to the risk for CIN (p<0.03). The MTHFR/p53 interaction showed that the genotype combinations AA/ArgArg and AA/ArgPro were associated, respectively, to the risk of ICC and CIN (p<0.05). This study suggests that the A1298C-MTHFR polymorphism contributes to the genetic risk for both CIN and ICC, whereas the Arg72Pro-p53 polymorphism only contributes to the risk for CIN. The MTHFR/p53 genetic combinations AA/ArgArg and AA/ArgPro are associated genetic risk factors for ICC and CIN in Mexican HPV-infected women.

Abstract Background: High-risk human papillomavirus (HR-HPV) infection is widely known as the major cause of cervical intraepithelial neoplasia (CIN) and cervical cancer and it’s characteristics vary greatly in different population. Women with abnormal cervical cytology could increase the risk of cervical cancer, however, HR-HPV infection characteristics in women with abnormal cervical cytology remains unclear. Methods: This study was based on baseline survey of the CIN Cohort established in Shanxi Province, China. A total number of 2300 women with cervical abnormalities were enrolled in this study. All participants gave informed consent and agreed to HPV and thinprepcytologic test (TCT). Each individual completed a questionnaire about characteristics related to HPV infection. Results: The overall prevalence of HR-HPV in 2300 women was 32.0%, and the proportion of single and multiple HR-HPV infections were 70.2% and 29.8% in HR-HPV infection women, respectively. The top five HR-HPV genotypes were ranked as HPV16, HPV58, HPV52, HPV53 and HPV51. The prevalence of HR-HPV in atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion and above(HSIL+) were 30.8%, 36.5% and 54.9%, respectively, showing an increasing trend with the severity of cervical cytology ( χ 2 trend =13.952; p <0.001). The women aged 35~45 years, with lower education level, less frequency of bathing, multiple gravidity, multiple parity, history of gynecological diseases and premenopausal women were prone to HR-HPV infection. Conclusions: We defined the characteristics related to HR-HPV infection in abnormal cervical cytology women, and provided an insight for the development and deeply research of HPV vaccine.

Introduction: Cancer cervix is a common genital cancer. Human papillomavirus is the main cause of cervical cancer because of the strong association of certain HPV genotypes and the development of cervical cancer and its precursor lesions, cervical intraepithelial neoplasia CIN 2 or CIN3. Methods: The study was conducted on 180 gynecological patients seen at the outpatient department of Manipal Hospital, Bangalore. A comparative study of HPV DNA test with Pap smear in the screening of cervical neoplasia was carried out over the period of 24 months from August 2011 to June 2013. Results: The incidence of cervical cancer and its associated mortality has declined in recent years, largely due to the widespread implementation of screening programs by Pap smear testing. The management and the prevention of cervical cancer should change with HPV DNA testing for high risk HPV, which is more sensitive than pap smear testing. Infection of cervix with HPV is necessary to cause cervical neoplasia and cervical cancer. Persistent infection with HPV is required for the development of cervical dysplasia and invasive cervical cancer. Conclusions: HPV testing alone for primary screening appears promising in women aged 30 years and older as this group is at greatest risk of developing CIN 3. As compared with Pap testing, HPV testing has greater sensitivity for detection of cervical intraepithelial neoplasia.

Introduction: Cervical cancer is a common health problem in Nepal. There is paucity of data regarding the spectrum of findings in cervical Pap in western Nepal. This study was aimed to study the cytological patterns in cervical Pap smears in patients in a tertiary hospital of Nepal. Methods: This is a prospective, cross sectional, hospital based study. Clinical features of patients who had presented with Pap smear was noted in a structured proforma. Pap smears were studied by a senior pathologist and reported based on revised Bethesda system (2014). Results: Most of the cases belonged to 31-40 years 399 (42.8%). Unsatisfactory/ inadequate sample was present in 133(14.05%) with obscuration due to inflammatory exudate being most common cause. Negative for intraepithelial lesion or malignancy rate was noted in 798 (85.54%) with 477(51.2%) being normal findings. Epithelial cell abnormalities were noted in 116 (14.5 %) smears. Low-grade squamous intraepithelial lesion constituted 321(34.5%), High grade squamous intraepithelial lesion 273(29.3 %) and Atypical squamous cells of undetermined significance 153(16.4%) of epithelial cell abnormalities. Squamous cell carcinoma was present in 9(1%) of all reviewed smears. There was no statistical significance between the age and abnormalities of Pap smear (p=0.9). Conclusions: Pap smear is pivotal in cervical cancer screening in developing countries. It also identifies various inflammatory, infective, benign and malignant pathologies at the earliest thereby decreasing the morbidity and mortality.
