Background: Cervical cancer can be invasive and advanced at diagnosis causing devastating suffering and premature death. Cancer stage at presentation is related to survival evaluation and several factors determine stage. The aim of the study was to examine predictors covariates associated with cervical cancer stage and its impact on patient prognosis and survival. Methods: This retrospective cross-sectional study was carried out at Khartoum oncology hospital, Sudan. Participants were 239 cervical cancer patients diagnosed and treated between 2011-2015. Patients’ pathological and socio-demographic data were extracted from their medical files and survival times calculated from follow-up. Chi-square, Kaplan-Meier, Log-rank test and Cox regression model were used to examine relationships between demographic and clinical variables and survival outcome. Results: The mean age of the participants was 56.91 years and the majority were ≥45 years. Cancer survival analysis showed that stage at diagnosis had limited association with socio-demographic factors, with the exception of where patients residing. Multivariate regression using the Cox proportional hazard model confirmed strongly that stage (p=0.035, chemotherapy (p=0.000) and radiotherapy (p=0.001) were the most likely predictor covariates of patient prognosis and survival time. Conclusions: The results of this study suggest cancer stage at diagnosis and certain treatments are the most important factors impacting prognosis and survival of patients with cervical cancer. Early detection and vaccination of women against HPV infection provide enormous opportunities for early diagnosis, more effective treatment and better chances of survival.

Human papillomavirus (HPV) is the most common sexually transmitted infection in the world. Several studies have shown a higher prevalence of HPV infection in HIV-infected women. The aim of this study was to determine the prevalence and the genotype diversity of HPV infection in HIV-infected women. From April 2010 to December 2012 cervical specimens were collected from 169 HIV-infected women who screening for cervical cancer at Reference Unit in Belém. The detection of HPV infection was performed by nested PCR and HPV type was performed using a commercial system. The prevalence of HPV infection was 63.3%. Of the 47 genotyped samples, 40.4% was found positive for high risk-HPV 16 and 12.8% for high risk-HPV 52. HPV infection was predominant in the group of women with no incidence of cytological abnormalities and more prevalent in women of reproductive age, unmarried, low education level, and who reported use condoms during sexual intercourse. It was observed an association between HPV infection and independent variables, such as condom use, multiple sexual partners, and history of sexually transmitted diseases. High-risk types of HPV infection were prevalent in our study. Infection with multiple high-risk HPV genotypes may potentiate the development of cervical cancer in HIV-infected women.

This paper highlights the low levels of vaccine coverage and high levels of reported vaccination hesitancy in Yerevan, Armenia, that present profound challenges to the control of disease through routine vaccination programmes. We draw on investigations of hesitancy towards the introduction of new vaccines, using the Human Papillomavirus (HPV) vaccine Gardasil as a case study, to interrogate underlying challenges to vaccine acceptance. We analyse primary data from the introduction of Gardasil, first used in Armenia in 2017, to investigate how levels of medical knowledge amongst physicians in 20 health facilities in Yerevan, Armenia, regarding vaccine science influence attitudes towards the introduction of a newly developed vaccine. A questionnaire-based cross-sectional study was completed by 348 physicians between December 2017 and September 2018. The responding physicians displayed a respectable level of knowledge and awareness regarding vaccination with respect to some characteristics (e.g., more than 81% knew that HPV infection was commonly asymptomatic, 73% knew that HPV infection was implicated in most cervical cancers, and 87% knew that cervical cancer is the most prevalent cancer amongst women) but low knowledge and poor understanding of other key issues such as the age at which women were most likely to develop cervical cancer (only 15% answered correctly), whether or not the vaccine should be administered to people who had already been infected (27% answered correctly) and whether sexually active young people should be treated for infection before vaccination (26% answered correctly). The study suggests that the drivers of vaccine hesitancy are complex and may not be consistent from vaccine to vaccine. The Armenian healthcare sector may need to provide additional training, awareness-raising and educational activities alongside the introduction of new vaccines to improve understanding of and trust in vaccination programmes.

Background: Cervical cancer is a leading cause of morbidity and mortality in women especially India. The mainstay of prevention rests on early detection of cases through screening. So, this study aims to determine the knowledge of cervical cancer screening, Human papilloma virus & its vaccination status. Methods: This was an observational study of cross-sectional design conducted among the adult reproductive aged women (18-45 years) visiting Gynaecology OPD at ESI-PGIMSR and ESIC Medical College and Hospital, Joka. A pre-designed and pre-tested interview schedule was prepared. Face to face interview was conducted in local language. Data was compiled & computed in SPSS software version 20. Results: Total respondents were 97. Majority of the respondents (62.9%) belong to the age group of 21-30 years. 8 in 10 participants follow Hinduism. Almost equal percentages of participants were from urban & rural areas (51.5% & 48.5% respectively). 6 in 10 participants had heard about cervical cancer. Majority of the respondents (55%) mentioned friends & family as a source of information. 48.3% of the respondents knew poor genital hygiene as a predisposing risk factor for cervical cancer. Very few knew about other factors like multiple sexual partner (20%), early marriage (33.3%), young age (20%), repeated childbirth (35%), OCP usage (26.7%) as risk factors for cervical cancer. Only one participant had undergone screening test for cervical cancer (1.7%). 46.7% of the respondents were aware about association of HPV infection with cervical cancer. But none of the participants had received vaccine against cervical cancer & they cited lack of awareness as a reason for not receiving the vaccine. Conclusions: A well-designed health education program focusing on effective multipronged IEC strategies utilizing pictorials, audio-visual and personal communication on cervical cancer could yield beneficial results.

Human papillomavirus (HPV) infection is one of the causes of cervical cancer which is preventable. The study was a cross-sectional study with the objective was to determine the Human papillomavirus (HPV) vaccination coverage among working women. A total 236 educated working women were selected purposively from different working places in Dhaka city. A pretested semi- structured questionnaire was used for data collection. The knowledge was assessed by using modified Blooms cut off points which was developed with cervical cancer and vaccine knowledge related questions. The study result revealed that among 236 working women 71.2% knew about the risk factor of cervical cancer. It was found that 92.8% knew about the way of prevention of cervical cancer respectively. The overall knowledge on cervical cancer and vaccine was found to be having good knowledge 21.2%, satisfactory knowledge 41.9% and poor knowledge 36.9%. Out of the total working women only 5.1% had HPV vaccination coverage. Reason behind non vaccinations, 50% mentioned had no knowledge about vaccine, 35.3% mentioned can’t decide and 8.9% mentioned high cost of vaccine. Significant association has been observed in between vaccination coverage with over all knowledge of cervical cancer (p value .04). It may be concluded that HPV vaccination coverage is very low which needs awareness program on this issues through mass media, educational session, counseling and so on to reduce human papillomavirus associated cancers as well as economic burden.

Background. The receptor-binding cancer antigen expressed on SiSo cells (RCAS1) is a human tumor-associated antigen that has been considered to play a crucial role in tumor progression by enabling cancer cells to evade immune surveillance. The present study aimed to evaluate the clinical significance of the RCAS1 expression in gastric adenocarcinoma.Material and Methods. RCAS1 protein expression was assessed immunohistochemically on 54 gastric adenocarcinoma tissue samples and was analyzed in relation to clinicopathological parameters, tumor proliferative capacity, and patients’ survival.Results. Enhanced RCAS1 expression levels were significantly associated with advanced histopathological stage and presence of organ metastasis (P=0.0084andP=0.0327). Gastric cancer patients with elevated RCAS1 expression levels showed significantly shorter survival times compared to those with low RCAS1 expression (log-rank test,P=0.0168). In multivariate analysis, histopathological stage and grade of differentiation as well as the RCAS1 expression were identified as independent prognostic factors (Cox regression analysis,P=0.0204,P=0.0035, andP=0.0081).Conclusions. Our data support the evidence that RCAS1 upregulation may contribute to gastric malignant progression, representing a useful biomarker to predict the biological behaviour and prognosis in gastric neoplasia.

5536 Background: Extensive tumor angiogenesis has correlated with poorer progression-free and overall survival in cervical cancer; however, specific markers of angiogenesis have not been studied prospectively. Methods: Cervical cancer patients with high-risk features on radical hysterectomy were eligible for randomization to adjuvant pelvic irradiation ± radiosensitizing platinum. Following central pathology review, formalin-fixed, paraffin-embedded tumors were sectioned into 4-micron specimens. Semi-quantitative immunohistochemisty (IHC) was performed using previously validated antibodies against mutant p53 (mp53), vascular endothelial growth factor (VEGF), thrombospondin-1 (TSP-1), and endothelial markers CD 31 and CD 105. Tumoral histoscores (HS) were calculated for mp53 and VEGF using the formula: [% cells positive × (intensity +1)], with a 5% threshold for positivity and intensity ranging 1–4+ (3+ = intensity of positive control). Intensity scores (0–4+) were assigned to TSP-1 specimens referencing the positive control (3+). MVD “hotspots” were counted in a 20X high-power field. HS and MVD counts were considered as continuous variables and TSP-1 intensity as an ordinal variable. Associations between markers were determined by Pearson’s and Spearman’s correlation tests, between markers and clinico-pathologic variables by Wilcoxon rank test, and between markers and survival by Cox regression modeling. Results: One hundred seventy-six specimens were analyzed. Acquisition of mp53 and increased VEGF expression were associated with increased MVD assessed by both CD31 (p=0.08 and p=0.002, respectively) and CD105 (p=0.02 and p=0.012, respectively). Statistically significant associations between markers and high-risk pathologic factors included: low-level TSP-1 and high CD-105 counts with lymph node metastases; high VEGF scores with advanced stage, non-squamous histologic subtype, and depth of tumor invasion; and high CD 31 counts with parametrial metastases. Survival analysis is currently being performed. Conclusions: Angiogenesis occurs early in cervical carcinogenesis, and may be a rational target for biologic therapy in cervical cancer. No significant financial relationships to disclose.

586 Background: The impact of intratumor heterogeneity on prognosis in metastatic colorectal cancer (mCRC) is unclear, however relative variant allele frequency (rVAF) of key mutations within a tumor may impact outcomes. Therefore, we sought to determine whether rVAF of RAS ( KRAS & NRAS) mutant (mt) clones impacts overall survival (OS) in mCRC patients (pts). Methods: Using a next generation sequencing panel of 201 cancer related genes, we tested 200 mCRC tumors / matched normals. Mutations, indels, and copy number variant (CNV) information were obtained. An rVAF of RAS clones was determined by dividing RAS mt VAF by the VAF of the mutated gene with the highest allele frequency. This truncal gene served as a marker of the total malignant population in a specimen. Pts were stratified at an rVAF of 50%. OS was compared with Kaplan-Meier curves, the log-rank test, and Cox regression. We assessed the impact of CNV on our findings by correcting the rVAF for CNVs in RASand truncal mutations. Results: Of 200 pts, 15% had RAS mt rVAF < 50%, 40.5% had rVAF ≥ 50%, and 44.5% were RAS wild type (WT). Age, gender, MSI status, histology, and stage at diagnosis were similar between groups. More RAS WT pts had BRAF mutations (19.1% vs 1.2% and 3.3%, P< 0.0001), left sided (78.7% vs 56.8% and 60%, P= 0.02), or poorly differentiated tumors (27.3% vs 8.6% and 13.3%, P= 0.003) compared to pts with rVAF ≥ 50% or rVAF < 50%, respectively. Mean coverage was 807x for RAS and 602x for truncal mutations. OS was better in pts with an rVAF < 50% compared to pts with rVAF ≥ 50% regardless of whether rVAF was corrected for CNV (HR 0.6; 95% CI 0.39-0.93, P =0.029) or not (HR 0.48; 95% CI 0.31-0.82, P= 0.010). mOS for pts with WT, rVAF < 50% and rVAF ≥ 50% tumors were 65.8, 55.7, and 38.6 months ( P= 0.0025). In multivariate models controlling for stage at diagnosis and BRAF mutation, pts with rVAF < 50% (HR 1.75; 95% CI 1.03-2.97, P = 0.04) and rVAF ≥ 50% (HR 2.46; 95% CI 1.66-3.65, P< 0.0001) had worse OS compared to WT pts. When rVAF was used as a continuous variable, every 1% increase in rVAF RAS mt resulted in a 1% increased hazard of death ( P <0.0001). Conclusions: Our findings suggest that clonal proportion of a tumor with a RAS mutation may impact OS and suggest the prognostic impact of RAS mutations is not an “all or none” phenomenon.
