Stage and histology of cervical cancer in women under 25 years old.

ABSTRACT: OBJECTIVE:To evaluate the histological and stage characteristics of cervical cancer in women under 25 years old, and to compare them with older women. METHODS:Cross-sectional study of cases from the Hospital Cancer Registry of São Paulo State/Brazil from 2000 to 2015. Variables were age, International Federation of Gynecology and Obstetrics stage and histological type. Prevalence ratio (PR) and its 95% confidence interval (CI) were calculated. RESULTS:Out of 18,423 cervical cancer cases 204 (1.1%) were in women under 25 years old. The most frequent stage was stage I in women under 25 (36.2%) and between 25 and 34 (43.4%), and stage III in older women (31.8%). No statistically significant difference was observed in stages by age group. Squamous carcinomas were the most frequent in 73.5% of women under 25 and 78.5% of older women. In women under 25 the following histological types were more frequent: neuroendocrine carcinomas (PR=6.10, 95% CI=2.03-18.35), malignant germ cell tumors (PR=54.98, 95% CI=26.53-113.95), mesenchymal tumors (sarcomas) (PR=5.67, 95% CI=2.58-12.45) and hematopoietic/lymphoid tumors (PR=0.72, 95% CI=2.90-36.69). CONCLUSION:In women under 25 years old cervical cancer was an uncommon diagnosis and in about one third occurred at early stage. Squamous carcinoma was the most frequent histological type regardless age, but rare histological types were more frequent in young women.

Project description:BACKGROUND:Cervical cancer is the most common cancer and a major cause of morbidity and mortality among women in Zimbabwe yet it is preventable, early detectable and highly curable. The objective of this study was to investigate knowledge, attitudes, beliefs and practices towards cervical cancer, its prevention and treatment in Harare, Zimbabwe. METHODS:Sequential explanatory mixed methods approach consisting of analytical cross sectional survey and a qualitative inquiry was used. Study population consisted of women with cervical cancer, health workers and other stakeholders who are involved in cancer control programmes. Patient survey data were collected using validated structured questionnaire in Surveytogo software in an android tablet. Qualitative study used key informant interviews to understand survey findings better. Data analyses for the survey involved univariate and multivariate analyses using STATA version 14. For qualitative study, themes in transcripts were coded and analyzed using Dedoose software to generate evidence for the study. RESULTS:Participants reported different levels of knowledge of causes (23%), risk factors (71%), prevention (72%), screening (73%) and treatment (80%) of cervical cancer. Knowledge of causes of cervical cancer were negatively associated with: being aged 45 or more years (OR = 0.02; p = 0.004), having no household income (OR = 0.02;p = 0.007), household income <US$600 per month (OR = 0.02; p = 0.015), middle class wealth (OR = 0.01;p = 0.032), watching TV daily (OR = 0.01;p = 0.007) and 1-6 times per week (OR = 0.02; p = 0.045). Knowledge of causes of cervical cancer were also positively associated with listening to radio daily (OR = 394, CI: 11.02-1406) (p = 0.001) and 1-6 times a week (OR = 100, CI: 2.95-3364) (p = 0.010). Knowledge of prevention was only positively associated with listening to the radio daily (OR = 77, CI: 1.89-3114) (p = 0.022) and 1-6 times a week (OR = 174, CI: 2.42-1255) (p = 0.018). Major drivers of lack of knowledge for cervical cancer were: limited awareness programmes, lack of knowledge among health workers, donor prioritization of infectious diseases, infancy of cervical cancer interventions, negative attitudes towards cervical cancer and misconceptions. CONCLUSIONS:This study revealed that knowledge of causes and prevention of cervical cancer was associated with frequent radio listenership. Strengthening of health education through the packaging of messages targeting the wider society using different delivery channels is thus recommended.

Project description:BackgroundWorldwide cervical cancer is the third most common malignancy in women. It usually arises from the cervical area which is susceptible to Human Papilloma virus induced malignancy changes. In low-resource setting visual inspection with acetic acid (VIA) is an alternative sensitive cervical screening method. Therefore the aim of this study was to assess the magnitude and associated factors of VIA positive test results for Cervical Cancer screening among Eritrean refugee women aged 25-49 years in northern Ethiopia refugee camps.MethodsA community based cross-sectional study was conducted among 412 Eritrean refugee women aged 25-49 years from august 10 to September 25, 2018. Study subjects were selected by simple random sampling method. Data were collected using pretested structured questioner through Face-to-face interview and cervical examination. Data were coded and entered to Epi info software version 7 and then exported to Statistical package for Social Science (SPSS) version 21 for analysis. Bivariable and multivariable logistic regression analysis was made to test the association between the independent variables and the outcome variable. P-value of less than 0.05 with 95% CI was considered to declare statistical significance.ResultIn this study the magnitude of VIA positive precancerous cervical lesions was 9% (95% CI: 6.3-11.8%). Previous history of sexually transmitted infections (STI) [AOR (95%CI) = 2.84(1.07-7.53)] and presence of STI during cervical examination [AOR (95%CI) =3.97(1.75-9.00)] were found significantly associated with VIA positive precancerous cervical lesions.ConclusionsIn this study the magnitude of VIA positive precancerous cervical lesions was high. Previous history of sexually transmitted infections (STI) and presence of STI during cervical examination were found associated with VIA positive precancerous cervical lesions. Efforts such as early screening for sexually transmitted disease shall be done to prevent precancerous cervical lesions.

Project description:BackgroundCervical cancer and human immunodeficiency virus prevention are public health priorities in Ethiopia. Despite cervical cancer being preventable with the Human Papilloma Virus vaccine and cervical cancer screening, HIV-infected women still have a low rate of screening, and data are scarce in this country. Thus, this study aimed to assess the prevalence of cervical cancer screening service utilization and associated factors among HIV-positive women in Southern Tigray, Ethiopia, 2018.MethodsA facility-based cross-sectional study was performed from March 1st to May 15th, 2018. We recruited 465 HIV-positive women using a systematic random sampling method. Data were collected using a pre-tested structured interviewer-administered questionnaire. Descriptive statistics, followed by multivariable logistic regression analysis were performed. Crude odds ratios, adjusted odds ratios, and 95% confidence intervals (CIs) were reported.ResultsIn this study, only 8% of HIV-positive women were screened for cervical cancer. The most frequently cited barrier by participants to getting screened was feeling healthy 282 (65.9%). Multiparity {AOR = 4.12, 95% CI = (1.70, 9.95)}, provider recommendation to get screened {AOR = 3.20, 95%CI = (1.34, 7.65)}, having good knowledge {AOR = 4.33, 95%CI = (1.66-11.29)}, and high perceived susceptibility for cervical cancer {AOR = 3.10, 95% CI = (1.31-7.33)} were the factors significantly associated with cervical cancer screening service utilization.ConclusionsThe prevalence of cervical cancer screening service utilization was quite low. Provider's recommendation to get screened, multiparity, knowledge, and perceived susceptibility were factors strongly associated with the service utilization. There is a need of routine counseling of health care providers for all HIV-positive women to get screened. Women's lack of knowledge also needs to be addressed by informing every HIV-positive woman that they are more susceptible to cervical cancer, and that screening is critical to fighting against the disease.

Project description:Aims: This study aims to develop a prediction tool for the overall survival of cervical cancer patients. Methods: We obtained 4116 female patients diagnosed with cervical cancer aged 25-69 during 2008-2019 from the Surveillance, Epidemiology, and End Results Program. The overall survival between groups was illustrated by the Kaplan-Meier method and compared by a log-rank test adjusted by the Bonferroni-Holm method. We first performed the multivariate Cox regression analysis to evaluate the predictive values of the variables. A prediction model was created using cox regression based on the training set, and the model was presented as a nomogram. The proposed nomogram was designed to predict the 1-year, 3-year, and 5-year overall survival of patients with cervical cancer. Besides the c-index, time-dependent receiver operating curves, and calibration curves were created to evaluate the accuracy of the nomogram at the timepoint of one year, three years, and five years. Results: With a median follow-up of 54 (28, 92) months, 1045 (25.39%) patients were deceased. Compared with alive individuals, the deceased were significantly older and the primary site was more likely to be the cervix uteri site, large tumor size, higher grade, and higher combined summary stage (all p values < 0.001). In the multivariate Cox regression, age at diagnosis, race, tumor size, grade, combined summary stage, pathology, and surgery treatment were significantly associated with the all-cause mortality for patients with cervical cancer. The proposed nomogram showed good performance with a C-index of 0.82 in the training set. The 1-year, 3-year, and 5-year areas under the curves (with 95% confidence interval) of the receiver operating curves were 0.88 (0.84, 0.91), 0.84 (0.81, 0.87), and 0.83 (0.80, 0.86), respectively. Conclusions: This study develops a prediction nomogram model for the overall survival of cervical cancer patients with a good performance. Further studies are required to validate the prediction model further.

Project description:BackgroundInherited susceptibility accounts for nearly one-third of colorectal cancer (CRC) predispositions and has an 80%-100% lifetime risk of this disease. However, there are few data about germline mutations of hereditary CRC-related genes in Chinese patients with CRC. This study aimed to assess the prevalence of gene mutations related to cancer susceptibility among Chinese patients with CRC, differences between Chinese and Western patients, and the phenotype-genotype correlation.MethodsWe retrospectively collected tumor samples from 526 patients with CRC under 70 years old who underwent hereditary CRC genetic testing. A series of bioinformatic analyses, as well as statistical comparisons, were performed.ResultsWe found that 77 patients (14.6%) harbored functional variants of the 12 genes. The mutation frequencies of the top 5 mutated genes were 6.5% for MutL homolog 1 (MLH1), 5.1% for MutS homolog 2 (MSH2), 1.0% for MSH6, 0.8% for PMS1 homolog 2 (PMS2), and 0.8% for APC regulator of the WNT signaling pathway (APC). Our data showed much higher rates of mutations of MSH6 and PMS2 genes among all mismatch repair (MMR) genes as compared with those in Western populations. Mutations in MLH1, MSH2, and MSH6 were found to be mutually exclusive. Patients with MLH1 or MSH2 mutations had higher frequencies of personal history of cancer (MLH1: 20.6% vs. 8.7%; MSH2: 25.9% vs. 8.6%) and family history of cancer than those without these mutations (MLH1: 73.5% vs. 48.4%; MSH2: 70.4% vs. 48.9%), and the lesions were more prone to occur on the right side of the colon than on the left side (MLH1: 73.5% vs. 29.3%; MSH2: 56.0% vs. 31.0%). The proportion of stage I/II disease was higher in patients with MLH1 mutations than in those without MLH1 mutations (70.6% vs. 50.7%), and the rate of polyps was higher in patients with APC mutations than in those with wild-type APC (75.0% vs. 17.4%).ConclusionThese results provide a full-scale landscape of hereditary susceptibility over 12 related genes in CRC patients and suggest that a comprehensive multi-gene panel testing for hereditary CRC predisposition could be a helpful analysis in clinical practice.
