Sifer SD. Survival status and predictors of mortality among cervical cancer patients at oncologic centers in Addis Ababa, Ethiopia: a follow up study. BMC Cancer 2024; 24:750. [PMID: 38902624 PMCID: PMC11188214 DOI: 10.1186/s12885-024-12518-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Accepted: 06/14/2024] [Indexed: 06/22/2024] Open
Abstract
BACKGROUND Cervical cancer (CC) ranks as the third most commonly diagnosed cancer and the fourth leading cause of cancer-related deaths among women globally. In Addis Ababa, there is a shortage of available evidence concerning the phenomenon of survival time and its predictors among women diagnosed with CC. Therefore, this study aimed to assess the survival status and predictors of mortality among CC patients at oncologic centers in Addis Ababa, Ethiopia. METHODS A facility-based retrospective cohort study was conducted among records of women with cervical cancer enrolled from the 1st of January 2017 to the 30th of December 2022 among 252 cervical cancer patients. Data were collected using a pretested, structured data collection checklist by trained data collectors. The Kaplan-Meier survival curve was used to estimate the survival time of the respondents. The Cox multivariable regression model was carried out to identify predictors of CC. Variables with P-value < 0.05 in multivariable analysis were declared as statistically significant. RESULTS The cumulative proportion of surviving at the end of the 10th and 20th month was 99.6% (95%CI: 97.02, 99.94) and 96.99% (95%CI: 93.41, 98.64), respectively. Similarly, it was 92.67% (95%CI: 87.65, 95.70), 85.9% (95%CI: 78.68, 90.94), 68.0% (95%CI: 57.14, 76.66) and 18.27% (8.38, 31.16) at the end of 30th, 40th, 50th and 60th monthly respectively. The overall median survival time was 54 months (95%CI: 52.6, 55.4). The incidence of death among a cohort of women with CC was 7.34 per 1000 person months. Being anemic (AHR: 4.77; 95%CI: 1.93, 11.77; P-value: 0.001), took a single cancer treatment (AHR: 1.92; 95%CI: 1.01, 3.64; P-value: 0.046) and HIV sero status positive (AHR: 2.05; 95%CI: 1.01, 4.19; P-value: 0.048) were statistically significant in multivariable cox proportional hazard model. CONCLUSION AND RECOMMENDATION Anemia, treatment initiation and HIV-sero status were independent predictors of mortality among women admitted with CC. It is imperative to enhance early screening initiatives and treatment resources for CC, alongside fostering public awareness through collaboration with various media outlets concerning preventive measures, screening procedures, and treatment alternatives for CC.

Inhibition of NF-kB and COX-2 by andrographolide regulates the progression of cervical cancer by promoting PTEN expression and suppressing PI3K/AKT signalling pathway. Sci Rep 2024; 14:12020. [PMID: 38797813 PMCID: PMC11128455 DOI: 10.1038/s41598-024-57304-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2023] [Accepted: 03/16/2024] [Indexed: 05/29/2024] Open
Abstract
In the face of recent advances in Cervical cancer (CC) treatment, therapeutic and surgical procedures for CC management are still inadequate. In the current study for the first time Andrographolide (Andro) has been explored for its multitarget therapeutic efficacy on NF-kB, COX-2, and PI3K/AKT expressions together in CC. The expression levels of NF-kB, COX-2, PI3K and PTEN in the CC patient samples, both at mRNA and protein levels have shown significant association with poor survival and increased tumor aggressiveness. The binding efficacy of Andro was investigated using molecular docking and molecular dynamic simulations, and the protein and ligand complex for NF-kB and COX-2 has shown high binding energy. Andro displayed cytotoxicity by impeding the in-vitro proliferation of CC cells. Andro significantly supressed the NF-kB, COX-2, and PI3K expression and enhanced the expression levels of PTEN at protein levels in-vitro. Andro induced apoptosis in a dose dependent manner and significantly inhibited the migration and invasion of CC cells. Andro exhibited similar activity in-vivo and suppressed the CC tumor growth in xenograft C57BL/6 mice model. The anti-tumor activity of Andro, both in-vitro and in-vivo has shown considerable downregulation of NF-kB and COX-2 and induced apoptosis through impeding the PI3K/AKT signalling pathway. These findings from the above study projects, administration of Andro as an effective alternate safe compound to curtail and impede cervical cancer progression.

Abstract
Cervical cancer is a significant global health concern, and novel therapeutic strategies are continually being sought to combat this disease. In recent years, selenadiazole found latent therapeutic effects on tumors. Herein, investigating the mechanism of selenadiazole in Hela cells holds promise for advancing cervical cancer treatment. Hela cells, a widely utilized model for studying cervical cancer, were treated with selenadiazole, and cell viability was assessed by using the cell counting kit-8 (CCK-8) assay. Changes in mitochondrial membrane potential were evaluated using JC-1 staining, while apoptosis induction was examined using AnnexinV-PI double staining. Intracellular ROS levels were measured by using specific fluorescent probes and the ELIASA system. Additionally, Western blotting was performed to assess the activation of related proteins in response to selenadiazole. Data analysis was performed using GraphPad. Exposure to selenadiazole led to a substantial increase in intracellular redox oxygen species (ROS) levels in Hela cells. Importantly, the induction of ROS by selenadiazole was associated with a marked increase in mitochondrial apoptosis, as evidenced by elevated levels of AnnexinV-positive cells, the JC-1 monomer, caspase-9, and Bcl-2. Furthermore, activation of the JAK2/STAT3 pathway was observed following the selenadiazole treatment. Selenadiazole holds the potential to suppress tumor growth in cervical cancer cells by increasing reactive oxygen species (ROS) levels and inducing mitochondrial apoptosis via the JAK2/STAT3 pathway. This study offers valuable insights into potential cervical cancer therapies and underscores the need for further research into the specific mechanisms of selenadiazole.

Abstract
This study highlights the oral health condition of female sex workers (SWs), who face increased risks associated with habits such as excessive alcohol and tobacco use. These behaviors heighten the likelihood of issues like oral cancer and dental diseases, underscoring the need for targeted health interventions. The study examines the oral health disparities between SWs and the general population (GP). A retrospective study analyzed the health records of 40 SWs and 40 controls matched by age and gender who were examined between 1 January 2020 and 30 May 2023. Intra-oral and panoramic radiographs, alongside clinical examination, were used to evaluate missing teeth, periodontal bone support, and caries. T-tests and chi-square tests were used to compare dental health indicators. A comparative analysis of these 80 patients revealed significant disparities: SWs had a higher incidence of missing teeth (5.8 ± 7.3 vs. 0.7 ± 1.4, p < 0.01) and caries (6.1 ± 6.2 vs. 0.8 ± 1.2, p < 0.05) compared to the GP. The DMFT (Decayed, Missing, and Filled Teeth) index was notably higher in SWs (16.1 ± 8.09) than in the GP (7.95 ± 5.48, p < 0.001). Additionally, 12% of SWs used removable dentures, unlike the GP. This study underscores significant oral health challenges in SWs, emphasizing the need for targeted healthcare strategies to improve their health conditions.

Early age at menarche and history of sexually transmitted infections significantly predict cervical cancer screening uptake among women aged 25-49 years: evidence from the 2021 Côte d'Ivoire demographic and health survey. BMC Health Serv Res 2024; 24:423. [PMID: 38570834 PMCID: PMC10993584 DOI: 10.1186/s12913-024-10881-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2024] [Accepted: 03/19/2024] [Indexed: 04/05/2024] Open
Abstract
INTRODUCTION Cervical cancer is the second dominant type of cancer among Ivorian women with an estimated age-standardised incidence and mortality rate of 31.2 cases and 22.8 deaths per 100,000 women in 2020, respectively. The Ivorian government through its Ministry of Health implemented the National Cancer Control Programme (NCCP) in 2003 with the aim of improving the prevention, early detection and treatment of cancers in Côte d'Ivoire. Yet, there is a low uptake of CCS (1.2%). Thus, making CCS uptake an important public health concern in the country. Understanding of the extent to which reproductive factors predict CCS uptake is limited in literature. This study aimed to investigate reproductive factors as a predictor of women's uptake of CCS in Côte d'Ivoire. METHODS Data from the 2021 Côte d'Ivoire Demographic and Health Survey. A sample of 9,078 women aged 25-49 years were analyzed. The outcome variable was CCS uptake while other variables considered included age at menarche, history of STI, sexual debut, parity, age, educational level, wealth index, health insurance, place of residence, and media exposure. A multivariable logistic regression model was fitted to examine the association between the outcome of interest and predictors at 95% confidence interval. RESULTS Approximately, 7.52% of women aged 25-49 years had ever undergone testing for cervical cancer by a healthcare provider. Early menarche was associated with lower odds of CCS uptake [AOR = 0.78; CI = 0.65-0.95]. Compared to those who had no STI, women with a history of STI were more likely to screen for cervical cancer [AOR = 2.63; CI = 2.02-3.42]. Increasing age, higher educational attainment, having health insurance, and being exposed to media were significantly associated with CCS uptake. CONCLUSION In Cote d'Ivoire, age at menarche and STI history constitute reproductive factors that were significantly associated with women's uptake of CCS. It is imperative for public policy to focus on increasing CCS in these higher-risk women (i.e., women who experienced early menarche, women with early sexual debut and higher parity) through increased sensitization on cervical cancer risk factors.

Abstract
Background Cervical lesions, often linked to high-risk human papillomavirus (HR-HPV) infection, pose a significant public health concern globally. Human HPV is considered the principal etiological factor in the development and transformation of pre-malignant lesions of the cervix leading to cervical carcinoma. The global distribution of HPV genotypes exhibits significant variability, liable to be influenced by the intricate interplay of geographical and biological factors among different HPV types and host immunogenetic elements. Owing to limited research addressing the genotypic distribution of HR-HPV in females with cervical lesions in the western zone of India, this study aims to bridge this gap by providing the prevalence of HR-HPV genotypes in women diagnosed with cervical lesions in this zone. Methodology This observational, cross-sectional study was performed in the Laboratory for Genotype Detection in the western zone of India. The study population comprised a total of 215 females in the age range of 18 to 60 years. A thorough examination of clinical specimens was conducted employing molecular techniques for HPV genotyping using TRUPCR® HPV-HR with a 16/18 Genotyping Kit. DNA Extraction was done using 3B Blackbio Biotech India Ltd. as per the standard protocol. The statistical analysis was performed using SPSS version 28 (IBM Corp., Armonk, NY, USA), and continuous variables were compared using Student's t-test. Results The overall prevalence of HR-HPV in women with cervical lesions in the western zone of India was 62.32% (134/215). The most prevalent genotype was HPV16 at 92/134 (68.65%), followed by HPV18 at 33/134 (24.62%) and HPV52 at 9/134 (6.7%). The overall prevalence of single type was 56.71% (76/134). The most prevalent genotype combination after HPV18 + 59 (29.85%) at 40/134 was HPV52 + 39 + 51 (13.43%) at 18/134. HR-HPV infection was found to be significantly (p < 0.05) associated with factors such as having three or more children, having a lower socioeconomic status, residing in rural areas, and being in a pre-menopausal stage. Conclusions This study focused on assessing the prevalence of the genotypes associated with HR-HPV infection, providing valuable insights into the epidemiology of cervical lesions in the western zone of India. The findings revealed high-risk genotype HPV16 to be the most prevalent type, followed by HPV18 and HPV52. The most prevalent genotype combinations were HPV18 + 59 and HPV52 + 39 + 51. The results of the study would potentiate the wealth of epidemiological data related to HPV infection in cervical lesions and could be employed for guiding future interventions and preventive strategies through orientation programs.

Abstract
BACKGROUND Human papillomavirus (HPV) is associated with cervical cancer and cervical dysplasia worldwide. Data on HPV prevalence in a region is important because it serves as a predictor of the likelihood of the population in that particular region acquiring cervical cancer. Moreover, with the availability of effective vaccines, the public health system must be aware of the preponderance of HPV to implement the vaccine. The present study was designed to understand the prevalence of HPV and associated factors among the women of South Andaman Island. METHODS A cross-sectional study was conducted among married women of reproductive age (18-59 years) from South Andaman District from 2018 to 2022. Cervical scrapes were collected from participants after obtaining informed written consent for HPV molecular testing (HPV DNA) such as PCR assay. Demographic data was collected using a standard questionnaire and statistical analyses were performed to determine the associated factors. RESULTS The study showed prevalence of HPV as 5.9%(95% CI: 3.9-7.9) and prevalence of HR-HPV16 was 4.1% (95% CI 2.6 - 5.5) and HR-HPV18 prevalence was 1.8(95% CI: 0.6-3). The independent factors associated the HPV positivity were age above 55 years, menopause, post-menopausal bleeding, blood-stained vaginal discharge and loss of weight. Age was associated with all HPV infections among the South Andaman women. CONCLUSIONS HPV 16 was reported as the predominant high risk HPV type circulating among women of South Andaman. Cervical cancer and precancerous lesions were significantly associated with HPV positivity and High risk HPV 16. Based on the knowledge of the risk factors associated with HPV, implementation of stronger public health awareness and prophylactic HPV vaccination is crucial among the women of this remote island.

Abstract
OBJECTIVE To introduce HPV self-sampling and out-reach colposcopy clinic as interventions to improve the follow-up of HPV positive women in a community based cervical cancer screening programme. METHODS This was a prospective observational study conducted during October 2017 to August 2019 and 2977 women underwent cervical cancer screening using CareHPV test. Follow up colposcopy for HPV positive women were conducted at the rural health center and alternatively as out-reach clinics in their own villages and default rates were compared. HPV positive women were followed up at one-year. They were given an option of either having a follow-up HPV test performed by a health care worker (HCW) or by self-sampling. Compliance to follow up in these two modalities were compared. A validated questionnaire was given to women who had given an HPV self-sample to assess their awareness about HPV and cervical cancer. RESULTS During our initial round of cervical cancer screening using HPV as a primary screening modality, our HPV screen positive rate was 7.05% (210 out of 2977 women screened). Our colposcopy rates following an initial invitation at the rural health centre was only 28.5%. Following this, we initiated out-reach colposcopy clinics at their own villages for HPV positive women and this increased colposcopy rates from 28.5% to 45.2%. The participation rate at one-year follow-up was increased from 40.5% to 60% by the introduction of self-sampling as a follow up option and 16.2% of women who were initially positive remained HPV positive at 12-14 months follow up. All women who were offered the option of self-sampling preferred it over a HCW collected sample. CONCLUSION Our study showed that self-sampling could also be used effectively in the follow up of HPV positive women in the community. Outreach colposcopy clinics in their own villages enabled better follow up of HPV positive women.

Abstract
Background Postmenopausal bleeding (PMB) is defined as blood loss from the genital tract occurring 12 months or more after an individual's last menstrual period. It is important for women to recognize abnormal symptoms during menopause, with PMB being one of the most critical. PMB is a common clinical presentation and can be indicative of endometrial carcinoma. A thorough clinical assessment and endometrial histopathology can ensure early diagnosis and treatment of malignancy in high-risk patients. Materials and Methods This study included 120 women with PMB. Their clinical and histopathological characteristics were studied, and correlations between the characteristics were investigated. Patients were evaluated according to their age, parity, duration of menopause, and socioeconomic status. Various comorbidities such as diabetes mellitus, hypertension, and obesity were noted. Results The patients ranged in age from 45 to 80 years, with a mean age of 54.97 ± 5.86 years. Fifty-nine (49.16%) of the patients presented with PMB within 3 years of menopause. PMB was seen most commonly in patients with parity 3, accounting for 37 (30.83%) of the cases. Endometrial thickness was increased in 100 (83.33%) cases. The most common causes of PMB were simple hyperplasia without atypia (SHWOA) in 36 (36%) patients and atrophic endometrium in 14 (14%) patients. Twelve (10%) of the patients had endometrial carcinoma. Benign causes of PMB were present in 91 (75.3%) cases, whereas 29 (24.1%) had a malignant cause. Weakly positive, but significant correlations (P < 0.05) were seen between the development of malignancy and increasing age (Pearson correlation coefficient, r = 0.263) parity (r = 0.244), and body mass index (r = 0.272). Conclusions PMB is considered abnormal. Benign causes are more common, but malignant causes are possible. In the current study, endometrial carcinoma was the most common malignant cause of PMB. Endometrial carcinoma incidence increased with greater endometrial thickness and more years since menopause. Histopathological examination remains the criterion standard for the correct diagnosis. Initiatives are recommended for increasing awareness about PMB to support prompt medical attention for a better prognosis.

Materials and Methods The present observational prospective study was done at the Department of Obstetrics and Gynecology at Teerthanker Mahaveer Medical College and Research Center for 18 months. All study subjects were subjected to Papanicolaou smear, VIA, and VILI examination. If any of these tests were found positive, then a colposcopy and cervical biopsy were done. Results The sensitivity of Pap, VIA, VILI, and colposcopy was 52.63%, 84.21%, 73.68%, and 84.21%, respectively. The specificity of Pap, VIA, VILI, and colposcopy was 60.0%, 80.0%, 60.0%, and 80.0%, respectively. The accuracy of Pap, VIA, VILI, and colposcopy was 54.17%, 83.33%, 70.83%, and 83.33%, respectively. Conclusion It is well known that VIA and VILI are very easy to carry out and apply. Even technically they do not cost much, consume less tax and can be applied to all the patients. Even the results are calculated in a faster manner which helps in chalking out the plan in an easy way.

Abstract
Objective Carcinoma cervix is one of the major cancers affecting Indian women. Concurrent chemo-radiotherapy is the standard of care in the treatment of carcinoma cervix. We aimed to study the outcomes and toxicity profile of volumetric modulated arc therapy (VMAT), an advanced modality of radiation delivery when used to treat patients with carcinoma cervix. Materials and methods Patients of carcinoma cervix belonging to FIGO (The International Federation of Gynecology and Obstetrics) stages IB2- IVA were recruited into the study. The patients were treated with VMAT to an EBRT (External Beam Radiation Therapy) dose of 50.4Gy in 28 fractions, which was followed by a brachytherapy schedule of 8Gy for each fraction to point A for three fractions. Toxicities were monitored weekly during the course of treatment and thereafter at every follow-up visit. A response assessment CECT (Contrast Enhanced Computed Tomography) scan was done three months after treatment and the response was recorded using RECIST (Response Evaluation Criteria In Solid Tumors) criteria. Results Sixty-four patients were available for analysis and most of the patients belonged to stage IIB (50.3%) followed by stage IIIB (28.5%). The complete response rate was 90.6% at three months and at a median follow-up of 12 months, the overall survival was 100% and disease-free survival was 89.1%. An analysis of clinically significant toxicities (grade 2 or worse) showed that diarrhea was the most common (20.3%) followed by proctitis (14%) and anemia (9.3%). Conclusion The results of the study established that volumetric modulated arc therapy is an acceptable modality of treatment of carcinoma cervix with an attractive toxicity profile. However, longer follow-ups will provide valuable information regarding the long-term disease control and late toxicities of the treatment.

Abstract
INTRODUCTION Breast cancer (BC) is globally prevalent and the leading cause of death due to cancer in females. Due to changes in risk factor profiles, improved cancer registration, and cancer detection, its incidence and death rates have risen over the past three decades. Both modifiable and immutable risk factors for BC make up a sizable portion of the total risk factors. Methodology: This was a hospital-based cross-sectional study carried out in the Department of Surgery, Rajendra Institute of Medical Sciences (RIMS), Ranchi. Consecutive sampling was done with a complete enumeration of all newly diagnosed cases of breast cancer >15 years old. Those who consented to participate and those who were extremely ill, deaf, or dumb were excluded from the study. RESULTS A total of 88 patients were included. Maximum patients diagnosed with breast cancer belonged to the age group of 40-50 years (37.5%), Hindu by religion (76.1%), non-tribal (80.68%), illiterate (89.8%), married (98.9%), housewives (92%), and of class IV socio-economic status (SES) (65.9%). CONCLUSION Regular training of Sahiya (the local name of Accredited Social Health Activist (ASHA) in Jharkhand), empowerment of screening clinics for cancer, and upgraded diagnostic facilities for timely referral should be stressed upon.

The impact of health education interventions on HPV vaccination uptake, awareness, and acceptance among people under 30 years old in India: a literature review with systematic search. FRONTIERS IN REPRODUCTIVE HEALTH 2023; 5:1151179. [PMID: 37215327 PMCID: PMC10198780 DOI: 10.3389/frph.2023.1151179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Accepted: 04/12/2023] [Indexed: 05/24/2023] Open
Abstract
Background The HPV vaccine is used as one of the main prevention tools for HPV-related cancers globally, yet it is not part of the Indian National Immunization program. In light of the introduction of the indigenous vaccine, we examine the effectiveness of health education about uptake, acceptance, and awareness. Methods Research was performed in the following databases: PubMed, CINAHL, Scopus, and Embase to identify studies between 2008 and 2022. Studies were included if: they were conducted in India including primary data research and health education intervention, and participants were between 9 and 29 years old. Results Out of the 10.952 results, 7 studies were included. Four studies focused on adolescent girls, aged from 9 to 20 years old, and 3 on university students aged from 17 to 26 years. Five studies were implemented in urban areas and 2 in rural areas. Health education interventions proved to be effective in increasing uptake, awareness, and acceptance of the HPV vaccine. The barriers included among others: cost, lack of awareness, and cultural barriers. Conclusion Observations from this study outline immediate action for policymakers to educate and encourage the young population toward HPV vaccination. Future programs should be aimed at different population groups and be adjusted according to their special characteristics and needs. Attention should be given to the male population and marginalized groups. The involvement of various stakeholders proved to be beneficial, and it is highly recommended.

Abstract
Background Rare cancers (RCs) are challenging to manage and are "forgotten cancers" though they collectively constitute a significant proportion of all cancers (∼20%). As a first step towards streamlining care, there is an unmet need to map the epidemiology of RCs in South Asian Association for Regional Collaboration (SAARC) countries. Methods The authors collected data from 30 Population-Based Cancer Registries (PBCR) of India and the published national registries of Nepal, Bhutan and Sri Lanka (SL) and compared them with the standard RARECAREnet RC list. Findings With the standard definition of crude incidence rates (CR) ≤6/100,0000 per population, 67.5%, 68.3%, 62.3% and 37% of all incident cancers qualify as RCs in India, Bhutan, Nepal and SL, respectively. An arbitrary cut-off CR ≤3 appears more appropriate with 43%, 39.5%, 51.8% and 17.2% of cancers identified as RCs, respectively, due to the lower cancer incidence.There are similarities and notable differences between the RC lists of the SAARC region with that of the European RC list. Oral cavity cancers are rare in Europe, while pancreas, rectum, urinary bladder and melanomas are common. In addition, uterine, colon and prostatic cancers are rare in India, Nepal and Bhutan. In SL, thyroid cancer is common. There are gender-related and regional differences in RC trends in the SAARC countries. Interpretation There is an unmet need in SAARC nations to capture epidemiological nuances in rare cancers. Understanding the unique issues in the developing world may guide policymakers to adopt appropriate measures to improve RC care and tailor public health interventions. Funding None.

Abstract
Objectives Cervical cancer is increasing worldwide and is becoming resistant to the existing drugs in clinical practice. Here, ethanolic extract of fruit body of Pleurotus florida was evaluated as antioxidant, anticancer agent against HeLa cell lines and anti-tumor against cervical cancer in mice model. Methods Fruit bodies of P. florida in 90% ethanol, and the P. florida ethanolic extract (PFEE) was subsequently investigated for its antioxidant content and activity, anticancer properties against the cervical cancer cell line, HeLa, and antitumor activity against HeLa implanted mice. Results The antioxidant activity bioassay showed that the IC50 of PFEE was 41.17 ± 1.42a μg/ml. The cytotoxicity assay revealed that PFEE caused inhibition of cell proliferation. At the highest dose (1,250 μg/ml) after 24 h, 48 h, or 72 h of treatment, the percentages of cell growth inhibition were 75.22%, 77.77%, and 84.65%, respectively. It revealed that PFEE-treated cells became rounded and the nuclei became fragmented. PFEE induced intracellular generation of reactive oxygen species and reduced the mitochondrial membrane potential. PFEE also led to an up regulation of the apoptotic genes for caspases-3, -9, and Bax, whereas Bcl-2 gene was down regulated, and it also promoted the expression of p53. Cell cycle analysis revealed that cell cycle was arrested at the G0/G1 checkpoint. PFEE suppressed metastasis and colonization. At a dosage of PFEE of 50 mg/kg of body weight, a 66.72% reduction in the size of tumors and an 87.44% reduction in the tumor weight were observed in mice. Conclusions It has demonstrated that PFEE is a highly potent anti-cervical cancer agent in vitro and in vivo.

Abstract
BACKGROUND Cervical cancer is a preventable disease if treated early, but remains the second leading cause of cancer-related mortality among women in low and middle-income countries. Data on epidemiology and risk factors in these settings are scarce. This study aimed to assess the prevalence of pre-cancerous cervical lesions and risk factors in Tigray region, Ethiopia. METHODS A community-based, cross-sectional study was used and 900 participants were 30 recruited using multistage sampling and finally data from 883 were collected using an interviewer administered questionnaire and screening with visual inspection with ascetic acid. Data were collected using an interviewer administered questionnaire and screening with visual inspection with acetic acid from March 2016 to June 2017. Multinomial logistic regression analysis was conducted to estimate predictors. RESULTS Seventy-nine (8.95%) women were positive for pre-cancer lesion and 35 (3.96%) were suspicious for cervical cancer. We used relative risk ratio (rrr) to estimate the strength of association. Divorced or widowed women had 2.5 and 4.7 times more risk of being positive and suspicious respectively, compared to single women (rrr = 2.5, 95% CI [1.13, 5.52]); (rrr = 4.69, 95% CI [1.00, 21.84]). The risk of having a suspicious result was 68% lower for women with primary education compared to those with no formal education (rrr = 0.32, 95% CI [1.00, 21.84]). History of sexually transmitted infection was associated with positive pre cancer lesion (rrr = 1.91, 95% CI [1.11, 3.27]) whereas, being farmer (rrr = 4.83, 95% CI [1.44, 16.13]), merchant (rrr = 4.85, 95% CI [1.52, 15.46]), bleeding between periods (rrr = 3.26, 95% CI [1.32, 8.04]) and pelvic or back pain (rrr = 2.79, 95% CI [1.18, 6.58]) were associated with suspicious for cancer. CONCLUSION About 8.9% and 3.96% of the women were positive for pre-cancerous cervical lesion and suspicious for cancer, respectively. The prevalence of pre-cancerous cervical lesion is high as compared to other regional prevalence in the country. Marital status, education, sexually transmitted infection, bleeding, and pelvic pain were risk factors of pre-cancerous cervical lesion'. This finding implies that the sexual exposure, having no permanent husband and being not educated attributes to the high prevalence of pre-cancerous cervical lesion and may aggravate the transmission of HPV."

Socio-economic and regional variation in breast and cervical cancer screening among Indian women of reproductive age: a study from National Family Health Survey, 2019-21. BMC Cancer 2022; 22:1279. [PMID: 36476339 PMCID: PMC9727878 DOI: 10.1186/s12885-022-10387-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Accepted: 11/30/2022] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND In India, breast and cervical cancers account for two-fifths of all cancers and are predominantly prevalent among women in the reproductive age group. The Government of India recommended screening of breast and cervical cancer among women aged 30 years and over. This study examines the socio-economic and regional variations of breast and cervical screening among Indian women in the reproductive age. METHODS A full sample of 707,119 women aged 15-49 and a sub-sample of 357,353 women aged 30-49 from National Family Health Survey-5 (2019-21) were used in the analysis. Self-reported ever screening for breast and cervical cancer for women aged 15-49 and women aged 30-49 were outcome variables. A set of socio-economic and risk factors associated with breast and cervical cancer screening were used as the predictors. Logistic regression was used to understand the significant correlates of cancer screening and, concentration index and concentration curve were used to assess the socio-economic inequality in breast and cervical cancer screening. RESULTS The proportion of breast and cervical cancer screening among women aged 30-49 were 877 and 1965 per 100,000 women respectively. Cancer screening was lower among women who were poor, young, had lower educational attainment and resided in rural areas. The concentration index was 0.2 for ever screening of breast cancer and 0.15 for cervical cancer among women aged 30-49 years. The concertation curve for screening of both breast and cervical cancers was pro-rich. Women with higher educational attainment [OR:1.46, 95% CI: 1.31-1.62], aged 40-49 years [OR:1.35; 95% CI: 1.28-1.43], resided in the western [OR:1.62; 95% CI:1.4-1.87] or southern [OR:6.66; 95% CI:5.93-7.49] region had significantly higher odds of up taking either of the screening. The pattern of breast and cervical cancer screening among women aged 15-49 was similar to that of women 30-49. CONCLUSION The overall proportion of cancer screening among women in 30-49 age group is low in India. Early screening and treatment can reduce the burden of these cancers. Creating awareness and providing knowledge on cancer could be a key strategy for reducing the burden of breast and cervical cancers among women in the reproductive age in India.

Abstract
Introduction cervical cancer is the fourth commonest cancer of women world-wide with increasing incidence in developing countries. This study determined the prevalence and assessed risk factors associated with precancerous cervical lesions among women in Cameroon. Methods this cross-sectional study enrolled 925 women participants of a screening campaign for precancerous cervical lesions from June to November 2018 in the selected hospitals. A convenience sampling technique was used and socio-demographic, sexual and reproductive data collected from consented participants by means of self-administered questionnaire. During the gynaecologic examination, a cervical smear was collected, stained by the Papanicolaou staining technique and the results classified according to the Bethesda 2014 guidelines. Frequency, percentage, Chi square and regression analysis were conducted using SPSS version 20 and p-value considered at 0.05. Results of the 925 participants aged 25-65 years (mean 40.2±10.2 SD), 113 (12.2%) had the lesions among whom 9 (7.9%) had atypical squamous cells of undetermined significance, 75 (66.4 %) had Low-grade squamous intraepithelial lesion and 29 (25.7%) had high-grade squamous intraepithelial lesion. Factors associated with the lesions were: age 1.85 [1.42-2.41; p= 0.001] and parity [OR= 1.46; 95% CI: 1.30-1.89; P= 0.004]. Conclusion the prevalence of precancerous lesions was 12.2%. Age, parity were significant risk factors. Regular screening targeting the population at risk in this study becomes a priority.

The different treatment options for carcinoma cervix include radiation, chemotherapy, and surgical treatments. Cytological analysis of smears is crucial for patient follow-up to determine response to therapy and to diagnose the persistence or recurrence of malignancy. Anatomical alterations and changes in cell morphology following radiation or chemotherapy make collecting and interpreting cervical cytology samples difficult. These issues can be mitigated by liquid-based cytology. Ionizing radiation is used in radiotherapy (RT) to kill cells. It is important that cytologists are aware of alterations in morphology of the cells. Radiation can cause cytoplasmic and nuclear changes. Cellular enlargement, vacuolation, granularity loss, and other changes linked with cell death are examples of cytoplasmic alterations. Nuclear enlargement and multinucleation are the most frequent nuclear alterations. These changes are determined by the amount of time that has passed since radiation. It should be emphasized that no one characteristic is pathognomonic. Post-irradiation dysplasia is a condition described as abnormal cellular changes in non-neoplastic epithelial cells after RT. Chemotherapy causes comparable alterations as radiation but impacts fewer cells. Busulfan and other chemotherapeutic treatments may produce morphological alterations, which cytologists must be aware of and able to identify. Immunosuppressive treatments, hormonal therapy, and tamoxifen are some of the other drugs that might cause changes in cervical morphology. Surgical methods used in the detection and treatment of cervical cancer may potentially cause alterations as a result of thermal damage and healing. For the treatment of cervical lesions, electrocautery and the loop electrosurgical excisional procedure are available. These procedures employ electric current ablation leading to ischemic changes in the cervical smear. Cytological analysis of smears following treatment with these modalities necessitates a comprehensive history, kind of therapy, and duration of treatment.

Abstract
Background Less literature is available on the performance of thermocoagulation for treatment of premalignant cervical lesions and its comparison with cryotherapy from low- and middle-income countries like India. Materials and Methods : A prospective randomized controlled study was done in the Department of Obstetrics and Gynecology from August 2018 to September 2019 after obtaining ethical clearance from Institutional Review Board (Reg no: ECR/262/Inst/Up/2013/RR/16) Ref no: 278/Ethics/R. cell-18). A total of 68 women with Visual inspection with acetic acid (VIA) positive cervical lesion were randomized into two groups. Group A was treated with cryotherapy and Group B was treated with thermocoagulation. Estimates of cure, adverse effects or complications were presented as frequencies, percentages, and mean ± standard deviation. Results Out of 667 patients, 624 patients underwent VIA testing among which 68 were VIA positive (10.89%, 68/624). The efficacy of thermocoagulation was 93.54% and that of cryotherapy was 90.32%. Immediate side effects were significantly lesser in thermocoagulation group (P = 0.008) in comparison to cryotherapy. Conclusion Thermocoagulation is better treatment modality than cryotherapy for VIA-positive cervical lesions may not be in terms of efficacy but definitely in terms of patient comfort and safety.

Assessment of Oral Human Papillomavirus Prevalence in Pediatric and Adult Patients within a Multi-Ethnic Clinic Population. Dent J (Basel) 2022; 10:dj10040054. [PMID: 35448048 PMCID: PMC9031267 DOI: 10.3390/dj10040054] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 03/07/2022] [Accepted: 03/23/2022] [Indexed: 11/17/2022] Open
Abstract
Introduction: Human papillomavirus (HPV) encompasses a large family of oncogenic viruses responsible for increasing rates of both cervical and oral cancer, particularly among minority and low-income populations. Although this represents an increasingly significant public health risk, few studies have screened for oral HPV within Nevada. Based upon this information, the primary objective of this study was to provide a temporal analysis of oral HPV screening among a primarily low-income, minority patient population. Methods: This retrospective analysis was reviewed and approved by the Institutional Review Board (IRB). In brief, unstimulated saliva samples were previously obtained from clinical patient volunteers who provided informed consent and pediatric assent (if applicable). DNA was isolated and screened using spectrophotometry for quality (A260:A280 ratio > 1.70) and quantity (concentration > 100 ng). Validated qPCR primers were used to screen repository samples for high-risk HPV strains HPV16 and HPV18. Results: A total of N = 930 samples were identified for this study, which involved n = 555 samples from adults and n = 375 from pediatric patients treated between 2011 and 2019. A demographic analysis revealed nearly equal distribution between males and females with most derived from non-White (minority) patients. A qPCR screening revealed an overall increase in high-risk HPV of 3.17-fold from 5.7% in 2011 to 18.1% in 2019 and a coefficient of determination or R2 = 0.764, suggesting a strong, positive correlation between more recent sample years and HPV-positive results, which was observed among both pediatric (R2 = 0.671) and adult (R2 = 0.971) patients. In addition, although the average age among adult patients increased over time, a significant decrease was observed among pediatric patients from an average of 16.0 years to 14.81 years. Conclusions: These data suggest temporal changes and positive increases in the prevalence of oral HPV among both the pediatric and adult patient samples taken from this clinic population. These data are important as considerations are made regarding which HPV vaccination education and awareness programs are introduced and the specific populations most likely to benefit from these interventions.

Abstract
Human papillomavirus (HPV) induced cervical cancer is becoming a major cause of mortality in women. The present research aimed to identify the natural inhibitors of HPV-18 E1 protein (1R9W) from Himalayan herbs with lesser toxicity and higher potency. In this study, one hundred nineteen phytoconstituents of twenty important traditional medicinal plants of Northwest Himalayas were selected for molecular docking with the target protein 1R9W of HPV-18 E1 Molecular docking was performed by AutoDock vina software. ADME/T screening of the bioactive phytoconstituents was done by SwissADME, admetSAR, and Protox II. A couple of best protein-ligand complexes were selected for 100 ns MD simulation. Molecular docking results revealed that among all the selected phytoconstituents only thirty-five phytoconstituents showed the binding affinity similar or more than the standard anti-cancer drugs viz. imiquimod (-6.1 kJ/mol) and podofilox (-6.9 kJ/mol). Among all the selected thirty-five phytoconstituents, eriodictyol-7-glucuronide, stigmasterol, clicoemodin and thalirugidine showed the best interactions with a docking score of -9.1, -8.7, -8.4, and -8.4 kJ/mol. Based on the ADME screening, only two phytoconstituents namely stigmasterol and clicoemodin selected as the best inhibitor of HPV protein. MD simulation study also revealed that stigmasterol and clicoemodin were stable inside the binding pocket of 1R9W, Stigmasterol and clicoemodin can be used as a potential investigational drug to cure HPV infections.

Abstract
AIM: This study aims to explore and analyze the effect of empowering women of childbearing age through the participatory action research method on cervical cancer prevention.
SETTINGS AND DESIGN: This was qualitative and quantitative approaches.
METHODS: A participatory action research approach to empower women of childbearing age and a quantitative pre-test and post-test without control approach was used to assess the changes that occur. Statistical analysis used: Paired t-test, to find out the mean difference before and after empowerment. Empowerment affects social changes in women of childbearing age in the prevention of cervical cancer. The Perwiritan and Moria groups not only carry out religious activities but also socialization and cervical cancer prevention campaigns.
RESULTS: The results showed that empowerment had an effect on increasing the average score of knowledge, attitudes, and actions of women of childbearing age in preventing cervical cancer (p < 0.05).
DISCUSSION: Empowerment of women of childbearing age is very effective in creating awareness, knowledge, attitudes, and actions in cervical cancer prevention. Empowerment can also be done for women in other communities.
CONCLUSION: There is an increase in understanding of women of childbearing age and the situation in which PAR is carried out because of the emergence of change agents among women of childbearing age who continue to have dialectics.

Abstract
Background Pathologically the cervix is affected by infective, inflammatory, and neoplastic diseases. Non‑neoplastic lesions of the cervix are seen often in sexually active women. Inflammatory lesions include chronic granulomatous cervicitis, acute and chronic cervicitis. In India, cervical cancer is a significant health problem. Many factors contribute to the differences in the spectrum of cervical diseases in the rural population compared to urban areas, but the studies in these populations are scarce. Materials and methods A retrospective analysis of all gynecological lesions over one year was studied. All case files were manually extracted, and the data was entered in an Excel sheet. The information included was clinical history (symptoms, signs, menstrual history, duration of illness, parity status), physical examination, per vaginal examination, investigations, including pathological diagnosis. The curated data was then analyzed using IBM SPSS for Windows version 22 (IBM Corp., Armonk, NY). Results There were 164 women in the study, with a mean age of 46.07 ± 8.17 years. A majority (n = 124, 75.6%) presented with excessive bleeding. Two-thirds of the study population had a normal cervix on examination. Twenty-seven women had squamous metaplasia, six had low-grade (LSIL) and high-grade squamous intraepithelial lesions (HSIL), and one had malignancy. Excessive bleeding was significantly associated only with LSIL. Among the microscopic findings, only squamous metaplasia (p < 0.001) and dysplasia (p < 0.001) were significantly associated with the final diagnoses, such as LSIL, HSIL, and chronic cervicitis. Conclusion Most studies involving rural populations have involved the knowledge, attitude, and practices of the study cohort rather than the histomorphological spectrum of cervical lesions. Since these disorders are also influenced by education, parity, hygiene, and socioeconomic status, it behooves us to be aware of the spectrum of cervical lesions in a rural cohort who differ in these aspects when compared to urban populations. Most of such lesions of the cervix in the population that our medical institution served were benign in nature.

Dendritic cells matured with recombinant human sperm associated antigen 9 (rhSPAG9) induce CD4 +, CD8 + T cells and activate NK cells: a potential candidate molecule for immunotherapy in cervical cancer. Cancer Cell Int 2021; 21:473. [PMID: 34493268 PMCID: PMC8424976 DOI: 10.1186/s12935-021-01951-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Accepted: 04/26/2021] [Indexed: 12/15/2022] Open
Abstract
Background Dendritic cell (DC)-based immunotherapy is capable of activating the immune system and in particular tumor-specific cytotoxic T lymphocytes (CTLs) to eradicate the tumor. However, major limitations are the availability of autologous tumor cells as antigenic source and the selection of antigen that may have potential to activate both CD4+ and CD8+ T cells in immune-specific manner. Recently, we reported the expression of sperm associated antigen 9 (SPAG9) that is associated with various types of malignancies including cervical cancer. We examined the recombinant human SPAG9 (rhSPAG9) as an antigenic source for generating efficient DCs to stimulate CD4+ and CD8+ T cell responses for future DCs-based vaccine trials in cervical cancer patients. Methods Human monocytes derived DCs were pulsed with different concentrations (250 ng/ml to 1000 ng/ml) of recombinant human SPAG9 (rhSPAG9) and evaluated for their phenotypic and functional ability. The efficacy of DCs primed with 750 ng/ml of rhSPAG9 (SPDCs) was compared with DCs primed with autologous tumor lysates (TLDCs), to induce CD4+, CD8+ T cells and activating NK cells. In addition, we investigated the effect of the chemotherapeutic drug cisplatin on phenotypic and functional potential of SPDCs. Results Phenotypic and functional characterization of DCs pulsed with 750 ng/ml rhSPAG9 was found to be optimal and effective for priming DCs. SPDCs were also capable of stimulating allogeneic T cells similar to TLDCs. SPDCs showed a statistically insignificant increase in the expression of maturation marker CD83 and migration towards CCL19 and CCL21 compared with TLDCs (CD83; P = 0.4; migration; P = 0.2). In contrast, although TLDCs showed better proliferation and secretion of Th1 cytokines (IL12p40, IL12p70 and IFNγ) compared to SPDCs, this difference was not statistically significant (IL12p40, P = 0.06). Further we also observed that clinical dose of cisplatin (200 µM) treated SPDCs were able to stimulate the proliferation of cytotoxic T lymphocytes without increasing the FOXP3+ Tregs in autologous co-cultures. Conclusions In summary, in order to overcome the limitation of the availability of autologous tumor cells as antigenic sources, our present strategy provides an insight to consider rhSPAG9 as a strong immunogen for DC-based immunotherapy for cervical cancer trials and warrants further studies. This is the first report to suggest that rhSPAG9 is an effective antigen for pulsing DCs that are capable of eliciting a potent Th1 response which, in turn, may help in decreasing the tumor burden when used along with a cisplatin based combinatorial regimen for therapeutic intervention.

Abstract
PURPOSE Although cancer is an important and growing public health issue in Nepal, the country lacked any population-based cancer registry (PBCR) until 2018. In this study, we describe the establishment of the PBCR for the first time in Nepal and use the registry data to understand incidence, mortality, and patterns of cancer in the Kathmandu Valley (consisting of Kathmandu, Lalitpur, and Bhaktapur districts), which comprises 10.5% of the estimated 29 million population of Nepal in 2018. MATERIALS AND METHODS The PBCR collects information from facilities and communities through the active process. The facilities include cancer or general hospitals, pathology laboratories, hospice, and Ayurvedic centers. In the communities, the field enumerators or female community health volunteers collected the data from the households. In addition, the Social Security and Nursing Division under the Department of Health Services, which provides subsidy for cancer treatment of underprivileged patients, was another major source of data. The collected data were verified for residence, accuracy, and completeness and then entered and analyzed using CanReg5 software. RESULTS In the Kathmandu Valley, the PBCR registered 2,156 new cancer cases with overall age-adjusted incidence rate for all cancers of 95.7 per 100,000 population (95.3 for males and 98.1 for females). The age-adjusted mortality rate for males was 36.3 (n = 365) and for females 27.0 (n = 305) per 100,000 population. We found that the commonest cancers in males were lung and stomach, whereas in females, they were breast and lung cancer. Gallbladder cancer was among the top five common cancers in both sex. CONCLUSION These findings provide a milestone to understand the cancer burden in the country for the first time using the PBCR and will be helpful to develop and prioritize cancer control strategies.

Abstract
BACKGROUND & OBJECTIVES Imaging has been added to the International Federation of Gynecology and Obstetrics (FIGO) 2018 staging system of cervical carcinoma. This study was performed to assess the impact of imaging in staging and to ascertain the prevalence and pattern of nodal metastasis on contrast-enhanced computed tomography (CECT) in patients with cervical carcinoma who were treated based on FIGO 2009 staging system. METHODS This retrospective study was conducted to evaluate all patients with biopsy-proven cervical carcinoma who underwent CECT of abdomen at a tertiary cancer centre in north India from April 2017 to April 2019 and for whom either baseline or follow up scans were available. In patients with enlarged or necrotic lymph nodes, the location, size and pattern of infiltration of adjacent organs were recorded. RESULTS A total of 602 patients of cervical carcinoma had undergone CT during the study period, of whom 138 (22.9%) underwent CT at baseline and 464 (77.1%) patients during follow up. The FIGO (2009) stage distribution at the time of presentation was stage IB: 109 (18.1%); stage IIA: 14 (2.3%), stage IIB: 118 (19.6%), stage IIIA: 12 (2%), stage IIIB: 277 (46%), stage IVA: 20 (3.3%) and stage IVB: 52 (8.6%). Ninety of the 138 (65.22%) patients underwent a stage shift according to the FIGO 2018 because of the presence of enlarged lymph nodes at baseline scan. Sixteen (2.7%) patients had infiltrative nodal masses most commonly involving the blood vessels (n=14) followed by ureter (n=8), bones (n=5), muscle and bowel (n=3, each). The majority (14/16) of these patients presented with vague abdominal pain, discomfort and vomiting, while two had bone pain. INTERPRETATION & CONCLUSIONS CECT at baseline helps in accurately assessing the stage in cervical carcinoma. It helps in the identification of lymph node metastasis in cervical carcinoma, which is crucial for guiding accurate management.

The characteristics and risk factors of human papillomavirus infection: an outpatient population-based study in Changsha, Hunan. Sci Rep 2021; 11:15128. [PMID: 34302031 PMCID: PMC8302608 DOI: 10.1038/s41598-021-94635-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Accepted: 06/28/2021] [Indexed: 11/08/2022] Open
Abstract
This cross-sectional study investigated the characteristics of cervical HPV infection in Changsha area and explored the influence of Candida vaginitis on this infection. From 11 August 2017 to 11 September 2018, 12,628 outpatient participants ranged from 19 to 84 years old were enrolled and analyzed. HPV DNA was amplified and tested by HPV GenoArray Test Kit. The vaginal ecology was detected by microscopic and biochemistry examinations. The diagnosis of Candida vaginitis was based on microscopic examination (spores, and/or hypha) and biochemical testing (galactosidase) for vaginal discharge by experts. Statistical analyses were performed using SAS 9.4. Continuous and categorical variables were analyzed by t-tests and by Chi-square tests, respectively. HPV infection risk factors were analyzed using multivariate logistic regression. Of the total number of participants, 1753 were infected with HPV (13.88%). Females aged ≥ 40 to < 50 years constituted the largest population of HPV-infected females (31.26%). The top 5 HPV subtypes affecting this population of 1753 infected females were the following: HPV-52 (28.01%), HPV-58 (14.83%), CP8304 (11.47%), HPV-53 (10.84%), and HPV-39 (9.64%). Age (OR 1.01; 95% CI 1-1.01; P < 0.05) and alcohol consumption (OR 1.30; 95% CI 1.09-1.56; P < 0.01) were found to be risk factors for HPV infection. However, the presence of Candida in the vaginal flora was found to be a protective factor against HPV infection (OR 0.62; 95% CI 0.48-0.8; P < 0.001). Comparing with our previous study of 2016, we conclude that the subtype distribution of HPV infection is relatively constant in Changsha. Our data suggest a negative correlation between vaginal Candida and HPV, however, more radical HPV management is required in this area for perimenopausal women and those who regularly consume alcohol.

Abstract
PURPOSE The COVID-19 pandemic has placed unprecedented demands on the health system. This led to delays in the initiation and completion of cancer treatment. We assessed the long-term health consequences because of the delay in diagnosis and treatment for cervical cancer due to COVID-19 in India. METHODS We used a Markov-model–based analysis assessing the lifetime health outcomes of the cohort of women population at risk from cervical cancer in India. The decrease in survival for those with the treatment interruption was calculated based on the number of days the treatment was extended beyond the standard duration. Furthermore, to model the impact of late diagnosis and delayed treatment initiation, the patients were assumed to have upstaged during the delay period, as per natural progression of disease. RESULTS We estimate 2.52% (n = 795) to 3.80% (n = 2,160) lifetime increase in the deaths caused by cervical cancer with treatment restrictions ranging from 9 weeks to 6 months, respectively, as compared to no delay. On the contrary, 88-238 deaths because of COVID-19 disease are estimated to be saved during this restriction period among the patients with cervical cancer. Overall, the excess mortality because of cervical cancer led to 18,159-53,626 life-years being lost and an increase of 16,808-50,035 disability-adjusted life-years. CONCLUSION Delays in diagnosis and treatment are likely to lead to more cervical cancer deaths as compared to COVID-19 mortality averted among the patients with cervical cancer. Health systems must reorganize in terms of priority setting for provision of care, starting with prioritizing the treatment of patients with early-stage cervical cancer, increasing use of teleconsultation, and strengthening the role of primary care physicians in provision of cancer care.

Abstract
Objective Cancer incidence across the geographical area is mercurial and factors like dietary habits, environment, social structure, genetics govern relative incidence. Malwa region of Punjab is one such geographical area of India speculated to have a higher incidence of cancer. The current analysis was done to assess the occurrence of cancer in the region and to analyze the trends and types of carcinoma with age, gender, site, and histopathological type, and to compare with the trends mentioned in the literature. Methods A retrospective analysis was done to collect and collate 2088 cancer patients' pathological records for three years at a tertiary treatment center. The collated data was digitized and used to create tables and histograms. Result Of the 2088 cancer cases, the leading cancer site was breast (24.7%) in females, followed by cancer of female genetic tract (18.9%), whereas in males, the most common site involved was head and neck (17.5%) followed by esophagus (10.3%). The leading cancer type for males was squamous cell carcinoma and for females was infiltrating ductal cell carcinoma. Breast carcinoma was most commonly seen cancer (40.5%) followed by female genital tract carcinoma and esophageal carcinoma in female patients. Whereas in males, head and neck carcinoma was most commonly identified (37.5%) followed by the gastrointestinal tract and esophageal carcinoma. This higher incidence may be attributed to better medical facilities, cancer awareness, and novel government schemes. Conclusion Based on our comprehensive analysis, we conclude that there was a change in trends of all types of carcinomas in males and females except breast carcinoma, which was seen as the most common carcinoma in female patients. Our findings suggest and support the strong implementation of cancer awareness programs and epidemiological studies to know the changing trends of risk factors in the region.

Abstract
Women living with HIV-1 are at high risk of infection with human papillomavirus of high carcinogenic risk (HR HPVs). M. tuberculosis (TB) promotes HPV infection and increases the risk to develop HPV-associated cancer. Our knowledge of persisting HR HPVs genotypes, and of the factors promoting HR HPV infection in people living with HIV-1 with clinical TB manifestations is sparse. Here, we analyzed 58 women living with HIV-1 with clinical TB manifestations (WLWH with TB) followed up in specialized centers in Russia, a middle income country endemic for HIV-1 and TB, for the presence in cervical smears of DNA of twelve HR HPV genotypes. DNA encoding HPV16 E5, E6/E7 was sequenced. Sociodemographic data of patients was collected by questionnaire. All women were at C2-C3 stages of HIV-infection (by CDC). The majority were over 30 years old, had secondary education, were unemployed, had sexual partners, experienced 2–3 pregnancies and at least one abortion, and were smokers. The most prevalent was HPV16 detected in the cervical smears of 38% of study participants. Altogether 34.5% of study participants were positive for HR HPV types other than HPV16; however, but none of these types was seen in more than 7% of tested samples. Altogether, 20.7% of study participants were positive for several HR HPV types. Infections with HPVs other than HPV16 were common among WLWH with generalized TB receiving combined ART/TB-therapy, and associated with their ability to work, indirectly reflecting both their health and lifestyle. The overall prevalence of HR HPVs was associated with sexual activity of women reflected by the number of pregnancies, and of HPV 16, with young age; none was associated to CD4+-counts, route of HIV-infection, duration of life with HIV, forms of TB-infection, or duration of ART, characterizing the immune status. Thus, WLWH with TB—especially young—were predisposed to infection with HPV16, advancing it as a basis for a therapeutic HPV vaccine. Phylogenetic analysis of HPV16 E5, E6/E7 DNA revealed no common ancestry; sequences were similar to those of the European and American HPV16 strains, indicating that HPV vaccine for WLWH could be the same as HPV16 vaccines developed for the general population. Sociodemographic and health correlates of HR HPV prevalence in WLWH deserve further analysis to develop criteria/recommendations for prophylactic catch-up and therapeutic HPV vaccination of this highly susceptible and vulnerable population group.

Abstract
In India, cervical cancer screening is conducted at various levels; however, after screening, the adherence to the cancer care continuum is barely understood. This study evaluated a community-based cancer screening program conducted in a rural setting (Tirunelveli and Tuticorin districts) in South India and reviewed the completion of care continuum. In this longitudinal descriptive study involving secondary data collection, data from the case records of 2192 women who were consecutively screened between March 2015 and May 2016 were included. All women underwent conventional cytology-based screening (Pap smear) and Visual Inspection with Acetic Acid (VIA). Those for whom either test was positive were referred for histopathological confirmation. Patients with confirmed precancerous conditions and unsatisfactory Pap smears were referred for further management. In total, 2192 women were screened [age range, 17-69 years; mean (standard deviation), 39.2 (8.5)]. Common symptom and sign were white discharge per vaginum (34.9%) and cervical erosion (34.4%), respectively. The VIA was positive for 24% (523/2178; 14 women did not cooperate for VIA) and 113 (5.1%) had epithelial cell abnormality in the Pap smear test. Per histopathology findings, one woman had non-keratinizing squamous cell carcinoma. Seven, three, and four had cervical intraepithelial neoplasia I, II and III, respectively. Of 2192, 807 were eligible for referral (597 had positive results on either Pap or VIA). Among the 807 women referred, only 74 (9.2%) women visited the referral center. The follow-up rate was very poor accounting to fragmentation of care continuum. The success of the screening program depends on the completion of the care continuum.

Abstract
Background: Cervical cancer is largely preventable. The study was aimed to find out the attributes of screening and vaccination for cervical cancer among female school teachers of Kota, Rajasthan, India. Methods: It was an observational study, cross-sectional in design conducted among female school teachers of Kota, Rajasthan, India using a predesigned structured questionnaire administered by Google Form during the months of March to May, 2020. In total, 397 schoolteachers from 18 different schools of Kota participated in our survey. Results: Among the study subjects, 33 (8.3%) had ever undergone screening for cervical cancer, whereas only 12 (3.0%) had taken vaccine against it. In multivariable logistic regression analysis; age (>40 years) [adjusted odds ratio (AOR): 5.7 (2.0-15.8)], correct knowledge regarding frequency of screening (yes) [AOR: 6.0 (2.4-15.5)], positive attitude for the disease (yes) [AOR:3.0 (1.1-8.0)] and gynaecologist consultation behaviour (periodic) [AOR: 1.4 (1.1-8.6)] were significant attributes of ever undergoing screening for cervical cancer. On the other hand, themultivariable significant attributes of vaccination were age (≤40 years) [AOR: 7.6 (1.5-38.9)]and positive attitude for the disease (yes) [AOR: 6.4 (1.1-38.2)]. Conclusion: Acceptance of screening and vaccination for cervical cancer among the study subjects was found to be quite low. Policymakers should more actively involve school teachers in generating awareness and in raising the demand for cervical cancer screening and vaccination in their native communities to curb the disease in the country.

Abstract
Cervical cancer is one of the most malignant reproductive diseases seen in women worldwide. The identification of dysregulated genes in clinical samples of cervical cancer may pave the way for development of better prognostic markers and therapeutic targets. To identify the dysregulated genes (DEGs), we have retrospectively collected 10 biopsies, seven from cervical cancer patients and three from normal subjects who underwent a hysterectomy. Total RNA isolated from biopsies was subjected to microarray analysis using the human Clariom D Affymetrix platform. Based on the results of principal component analysis (PCA), only eight samples are qualified for further studies; GO and KEGG were used to identify the key genes and were compared with TCGA and GEO datasets. Identified genes were further validated by quantitative real-time PCR and receiver operating characteristic (ROC) curves, and the highest Youden index was calculated in order to evaluate cutoff points (COPs) that allowed distinguishing of tissue samples of cervical squamous carcinoma patients from those of healthy individuals. By comparative microarray analysis, a total of 108 genes common across the six patients' samples were chosen; among these, 78 genes were upregulated and 26 genes were downregulated. The key genes identified were SPP1, LYN, ARRB2, COL6A3, FOXM1, CCL21, TTK, and MELK. Based on their relative expression, the genes were ordered as follows: TTK > ARRB2 > SPP1 > FOXM1 > LYN > MELK > CCL21 > COL6A3; this generated data is in sync with the TCGA datasets, except for ARRB2. Protein-protein interaction network analysis revealed that TTK and MELK are closely associated with SMC4, AURKA, PLK4, and KIF18A. The candidate genes SPP1, FOXM1, LYN, COL6A3, CCL21, TTK and MELK at mRNA level, emerge as promising candidate markers for cervical cancer prognosis and also emerge as potential therapeutic drug targets.

OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:6692628. [PMID: 33815659 PMCID: PMC8010528 DOI: 10.1155/2021/6692628] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 02/03/2021] [Accepted: 02/19/2021] [Indexed: 11/18/2022]
Abstract
This work is aimed at investigating the expression levels of inducible nitric oxide synthase (iNOS) in cervical cancer and identifying a potential iNOS inhibitor. The data mining studies performed advocated iNOS to be a promising biomarker for cancer prognosis, as it is highly overexpressed in several malignant cancers. The elevated iNOS was found to be associated with poor survival and increased tumor aggressiveness in cervical cancer. Immunohistochemical and RT-PCR investigations of iNOS showed significant upregulation of endogenous iNOS expression in the cervical tumor samples, thus making iNOS a potent target for decreasing tumor inflammation and aggressiveness. Andrographolide, a plant-derived diterpenoid lactone, is widely reported to be effective against infections and inflammation, causing no adverse side effects on humans. In the current study, we investigated the effect of andrographolide on the prognostic value of iNOS expression in cervical cancer, which has not been reported previously. The binding efficacy of andrographolide was analyzed by performing molecular docking and molecular dynamic simulations. Multiple parameters were used to analyze the simulation trajectory, like root mean square deviation (RMSD), torsional degree of freedom, protein-root mean square fluctuations (P-RMSF), ligand RMSF, total number of intramolecular hydrogen bonds, secondary structure elements (SSE) of the protein, and protein complex with the time-dependent functions of MDS. Ligand-protein interactions revealed binding efficacy of andrographolide with tryptophan amino acid of iNOS protein. Cancer cell proliferation, cell migration, cell cycle analysis, and apoptosis-mediated cell death were assessed in vitro, post iNOS inhibition induced by andrographolide treatment (demonstrated by Western blot). Results. Andrographolide exhibited cytotoxicity by inhibiting the in vitro proliferation of cervical cancer cells and also abrogated the cancer cell migration. A significant increase in apoptosis was observed with increasing andrographolide concentration, and it also induced cell cycle arrest at G1-S phase transition. Our results substantiate that andrographolide significantly inhibits iNOS expression and exhibits antiproliferative and proapoptotic effects on cervical cancer cells.

Abstract
Objective Cervical cancer is a gynecological health problem, affecting nearly 500,000 women each year worldwide. Genome‐wide association studies have revealed multiple susceptible genes and their polymorphisms for cervical carcinoma risk. We have carried out this case‐control study to investigate the association of INSIG2 rs6726538 (A; T), HLA‐DRB1 rs9272143 (T; C), and GCNT1P5 rs7780883 (G; A) with cervical cancer. Methods The present study recruited 234 cervical cancer patients as cases and 212 healthy females as controls. We have applied the tetra‐primer amplification refractory mutation system polymerase chain reaction (T‐ARMS‐PCR) method for genotyping. Results The SNP rs6726538 was significantly associated with increased risk of cervical cancer in all genetic models (AT vs. AA: OR = 3.30, 95% CI = 2.19–4.97, p < 0.0001; TT vs. AA: OR = 8.72, 95% CI = 3.87–19.7, p < 0.0001; AT+TT vs. AA: OR = 3.87, 95% CI = 2.61–5.73, p < 0.0001; T vs. A: OR = 2.97, 95% CI = 2.20–4.01, p < 0.0001) except the recessive model which showed a significantly reduced risk (TT vs. AA+AT: OR = 0.20, 95% CI = 0.09–0.44, p = 0.0001). rs9272143 showed significantly reduced risk for the additive model 1, dominant model, and allelic model (TC vs. TT: OR = 0.46, 95% CI = 0.31–0.70, p = 0.0004; TC+CC vs. TT: OR = 0.47 95% CI = 0.32–0.70, p = 0.0002; C vs. T: OR = 0.56, 95% CI = 0.40–0.78, p = 0.0006, respectively). The third variant, rs7780883, was significantly associated with increased risk in additive model 2, dominant, and allelic models (AA vs. GG: OR = 5.08, 95% CI = 2.45–10.5, p < 0.0001; GA+AA vs. GG: OR = 1.54, 95% CI = 1.06–2.24, p = 0.0237; A vs. G: OR = 1.88, 95% CI = 1.34–2.52, p < 0.0001, consecutively), whereas recessive model reduced the risk of cervical cancer (AA vs. GG+GA: OR = 0.20, 95% CI = 0.09–0.41, p < 0.0001). Other models of these SNPs were not associated with cervical cancer. All significant associations for three SNPs withstand after Bonferroni correction except the additive model 2 of rs7780883. Conclusion Our study concludes that INSIG2 rs6726538, HLA‐DRB1 rs9272143, and GCNT1P5 rs7780883 polymorphisms may contribute to the development of cervical cancer in the Bangladeshi population.

Abstract
Background Genital tract malignancies have a significant contribution to morbidity and mortality, particularly in resource-poor countries, including Sri Lanka. The distribution of such tumours varies from region to region. Methodology This was a retrospective, observational study at the Teaching Hospital, Batticaloa for five and a half years, from January 2012 to June 2017, and aimed at analyzing the pattern of gynaecological malignancies. All the histologically confirmed gynaecological cancers arising from the uterine cervix, endometrium, ovary, vagina, and vulva were included in the analysis. Results There were 508 cervical specimens to study histopathology of the cervix, 1,884 gynaecological specimens to study the endometrial histopathology, 537 ovarian specimens, and 92 vaginal and vulval specimen were sent for their histopathological study during the same period. About 143 genital tract malignancies had been diagnosed. There were 52 cervical malignancies (36.36%) and 52 ovarian malignancies (36.36%). The second commonest (20.28%) was endometrial malignancy. Vaginal malignancy was at fourth place (4.9%). Vulval malignancy was 2.1%. The peak age distribution of malignancies (55.24%) was mainly in the 40-59 years age range. The incidence of cervical and ovarian malignancies peaked at 40-59 years, with 32/52 (61.54 %) and 26/52 (50%) of the diagnosed cases, respectively. Conclusion Cervical cancer and ovarian cancer accounted for almost 72.73% of the entire gynaecological malignancies in this study, and both of them have the same peak incidence in the 40-59 age group. This study also showed that 43.36% of total female genital tract tumours are Human Papilloma Virus-associated cancers. They are not only preventable by certain strategies but also identifiable and manageable at the precancerous stage.

Abstract
Cervical cancer is the second most common cause of cancer-related death among women worldwide, especially in developing countries. Oxidative stress has been associated with cervical cancer. Many studies demonstrated that the low level of antioxidants induces the production of free radicals that cause lipid peroxidation, DNA, and protein damage leading to mutations that favors malignant transformation. This is a case-control institutional study conducted to evaluate the level of oxidative stress in cervical cancer patients and the age-matched healthy controls. We measured level of TBARS expressed as MDA, activity of SOD and GSH level by the spectrophotometric method, and level of 8-OHdG was estimated using a competitive sandwich ELISA assay. Our results showed a significant increase in the level of lipid peroxidation in group IV when compared to the control, group II and group III (p < 0.001). The activity of SOD was also significantly higher in group IV when compared to the control group (p < 0.001), group II (p < 0.001), and group III (p < 0.001). The level of GSH was also significantly lower in group IV when compared to the control group (p < 0.01), group II (p < 0.01), and group III (p < 0.01). The level of 8-OHdG was significantly higher in group IV than in the other groups (p < 0.01). The results suggest that oxidative stress is involved in the pathogenesis of cervical cancer, which is demonstrated by an increased level of lipid peroxidation and higher levels of 8-OHdG and an altered antioxidant defense system.

Abstract
India contributes to 1/3rd of worldwide cervical cancer deaths caused by HPV. High risk human papillomavirus (hr-HPV) 16 and 18 infections are responsible for more than 70% of cases. Early detection of hr-HPV infection can help in prevention and disease management. In rural India, HPV infection is uncontrolled due to poor hygiene, lack of awareness, screening, and vaccination. Hence, our study aims to screen HPV infection in central India starting with Anuppur district of MP. Married women above 15 and women with or without clinical conditions were recruited for the study. Unmarried, pregnant and women with cervical cancer history were excluded. A cross-sectional study was conducted on 782 enrolled married adolescents and middle aged women by obtaining clinical information and cervical swabs between March 2019 to March 2020. Genomic DNA was extracted and screened for HPV using MY09/11 and HPV-16 specific primers, data was analysed using IBM-SPSS statistics software. An overall prevalence of 7.1% HPV infection was observed, and a significant incidence (95%) of hr-HPV 16 genotype was found. There was a considerable decrease in HPV prevalence with age; young adults between 15 and 29 years (86.4%) followed by women aged between 30 and 54 years (13.2%). Among positives, hr-HPV-16 prevalence was not significantly different among the different age-groups (p > 0.05). Hr-HPV-16 infection was detected highest in Scheduled Tribes (ST) 70%, followed by other categories. Interventions such as screening and awareness programs will help in better management of HPV infection.

Abstract
Background: Cancer cervix and breast are the two major female health problems in India. A hospital-based, 5-year (2010–2014) retrospective study was conducted at a regional cancer center of Odisha to analyze the present burden of cancer cervix in this state, which has a population of more than 45.5 million at present. Materials and Methods: All the patients suffering from cancer cervix that was treated by radiotherapy during 2010–2014 at this center were analyzed year wise for age, stage of disease, and native area. Results: Based on the Census 2011 data, it was calculated and found that from the low-literacy area on an average of 4.62 cervical cancer patients per million, from the medium-literacy area 6.56 patients per million, and from high-literacy area 19.11 patients per million of population have received radiotherapy in this hospital. More than 60% of patients with cervical cancer were from stage IIIB and in the age group of 50–55 years. Discussion: Odisha has 83.7% female population in rural areas with literacy rate below 50%. Due to lack of awareness and unavailability of cancer care facilities at their reach, they mainly depend on various alternative medicines in unscientific manner for their health care. Conclusion: Strengthening of existing regional cancer center, development of oncology wings in all medical college hospitals by providing basic radiotherapy facilities, emphasizing more on district cancer control programs, decentralizing of NGO schemes, and facilitating with more cancer screening and awareness programs may help better registration, prevention, and treatment of cancer in Odisha.

Abstract
The aim of the study is to investigate the expression of angiogenesis (VEGF and PDGF), angiogenesis inhibitor markers (angiostatin and endostatin), proliferation (Ki67), and apoptosis markers (p53 and p16) of cervical cancer in Indian population and to correlate them with the clinicopathological profile. It is a descriptive study of consecutive cases of cervical cancer from Saveetha Medical College and Hospital between January 2017 and December 2018. The expression of angiogenesis, angiogenesis inhibitor markers, Ki67, p53, and p16 in 60 cases of cervical sections were detected by the immunohistochemical method and analyzed with clinicopathological data. VEGF expression was positive in 16 cases (26.67%) and negative in 20 cases (33.33%). As of PDGF, 3 cases (3.33%) have shown positivity to PDGF and 33 cases have shown negativity. Angiostatin and endostatin expression was reported to be positive in 10 (16.67%) and 21 (35%) cases, respectively. Most of the cases 57 (95%) have shown both p16 and Ki67 positivity. Although p53 expression was positive in 48 cases (80%), the remaining 12 cases (20%) were p53-negative. The PDGF expression was significantly correlated to the stage of tumors. No statistically significant association was observed between angiogenesis inhibitor markers and clinicopathological parameters. A significant positive correlation was noticed between the Ki67 expression and stage of tumors.

Abstract
SIGNIFICANCE Mueller matrix polarimetry can provide useful information about the function and structure of the extracellular matrix. A portable and low-cost system could facilitate the clinical assessment of cervical anomalies in low-resource settings. AIM We introduce a low-cost snapshot Mueller matrix polarimeter that does not require external power, has no moving parts, and can acquire a full Mueller matrix in ∼1 s, to conduct a feasibility study for cervical imaging in the low-resource setting. APPROACH A snapshot system based on two sets of Savart plates, a ring illuminator with polarizing elements (generating four polarization states), and one camera is introduced. Stokes vectors are formulated to recover the polarization properties of the sample. Then, using Mueller matrix decomposition, the depolarization and retardance information is extracted. RESULTS We report the results on 16 healthy individuals (out of 22 patients imaged), whose Pap smear showed no malignant findings from mobile clinics in rural region of Mysore, India. The depolarization and retardance information was in agreement with previous reports. CONCLUSIONS We introduce an imaging system and conducted a feasibility study on healthy individuals. This work could futurely translate into diagnostic applications to provide a quantitative platform in the clinical environment (e.g., cervical cancer screening).

Abstract
Background and Aims: Human papilloma virus (HPV) infection is the most common sexually transmitted infection responsible for cervical cancer in women. There is no cure for HPV but safe and effective vaccinations before sexual debut can definitely decrease the incidence of cervical cancer. This research aims to explore the basic understanding of medical students about cervical cancer, HPV and HPV vaccination. Methods and Material: This was a descriptive, questionnaire based cross-sectional study conducted among the undergraduate medical students of All India Institute of Medical Sciences, Jodhpur from April 2018 to May 2018. A total of 238 respondents participated in the study. For statistical analysis, 'Z' score was used for categorical data and student t test was used for normally distributed continuous data. Results: Overall, 41% students had good knowledge about HPV infection and HPV vaccination while 44% students had average knowledge and 15% had poor knowledge. The majority of them (>80%) knew that HPV is responsible for cervical cancer and ano-genital warts but their awareness was not of the same order when it came to associating HPV with penile and oropharyngeal cancer (60%). Females had better knowledge as compared to males and this difference was statistically significant (P < 0.05). 88% of the students were willing to accept the vaccination while only 10% of females were previously vaccinated. Conclusion: Medical students, who are potential recipients of the HPV vaccine themselves, can play a unique role in promoting awareness about HPV vaccination in the future.

Abstract
BACKGROUND As per WHO, Cervical cancer (CaCx) is a global issue, being the fourth common cancer in women with incidence rate of 13.1 per 1 lakh women globally and accounting for 311000 deaths in the year 2018 itself globally. The molecular pathogenesis in Human papillomavirus (HPV) infected cases is inconclusive. The detection of molecular factors leading to progression of CaCx can be important in the diagnosis and management of the disease. p53 a known tumor suppressor gene having a regulative role in cell cycle has been highlighted as key factor in the prevention of cancer but its significance in CaCx cases has been variably documented. The present study therefore targeted to evaluate the significance of p53 profile in CaCx cases in ethnically distinct northeast Indian population. METHODS Blood and Tissue samples (N = 85) of cervical cancer patients were collected and screening for HPV was performed using PCR. Thereafter the differential mRNA expression(qPCR), Immunohistochemistry, Mutation (PCR direct sequencing method) of p53 was studied. Further p53 epigenetic profiling was done by Methylation specific PCR (MS-PCR) and western blotting by using p53 acetylation specific antibodies. RESULTS Our findings revealed that the downregulation of p53 was associated with the progression of disease and the variation in downregulation based on p53 polymorphism was observed. Further hypermethylation and deacetylation of p53 was also found to be associated with the pathogenesis of CaCx. The downregulated expression and hypermethylation of p53 in lower grade of CaCx, together established its association with the progression of CaCx from lower to severe grade. CONCLUSION Therefore, in CaCx patients of northeast Indian population, malfunctioning of p53 is found to have significant role in cervical cancer progression.
