RESUMO

PURPOSE: Reducing time between cancer screening, diagnosis, and initiation of treatment is best achieved when services are available in the same hospital. Yet, comprehensive cancer centers are typically unavailable in low- and middle-income countries (LMICs), where resources are limited and services scattered. This study explored the impact of establishing an in-house pathology laboratory at the largest public cancer hospital in Tanzania on the downstaging of cervical cancer. METHODS: We examined clinical datasets of 8,322 cervical cancer patients treated at the Ocean Road Cancer Institute (ORCI). The first period included patients treated from 2002 to 2016, before establishment of the pathology laboratory at ORCI; the second period (post-pathology establishment) included data from 2017 to 2020. Logistic regression analysis evaluated the impact of the pathology laboratory on stage of cervical cancer diagnosis. RESULTS: Patients treated during the post-pathology period were more likely to be clinically diagnosed at earlier disease stages compared to patients in the pre-pathology period (pre-pathology population diagnosed at early disease stage: 44.08%; post-pathology population diagnosed at early disease stage: 59.38%, p < 0.001). After adjustment for age, region of residence, and place of biopsy, regression results showed patients diagnosed during the post-pathology period had higher odds of early stage cervical cancer diagnosis than patients in the pre-pathology period (OR 1.35, 95% CI (1.16, 1.57), p < 0.001). CONCLUSIONS: Integrated and comprehensive cancer centers can overcome challenges in delivering expedited cervical cancer diagnosis and treatment. In-house pathology laboratories play an important role in facilitating timely diagnosis and rapid treatment of cervical and possibly other cancers in LMICs.

RESUMO

BACKGROUND: Indigenous women are vulnerable to cervical cancer. Screening is a strategy to reduce the burden of the disease. OBJECTIVE: To evaluate the prevalence profile of cervical cancer screening cytological results in Brazilian indigenous women by age and frequency of tests compared to non-indigenous women. METHODS: A cross-sectional study evaluating the prevalences of screening test results in indigenous women assisted in the Brazilian Amazon from 2007 to 2019 (3,231 tests), compared to non-indigenous women (698,415 tests). The main outcome was the cytological result. Other variables were frequency, age groups, and population. The frequency was categorized as "1st test", the first test performed by the women in their lifetime, or "screening test," tests from women who had previously participated in screening. Analyzes were based on prevalences by age group and population. We used Prevalence Ratios (PR) and 95% Confidence Intervals for risks and linear regression for trends. RESULTS: Data from the 1st test showed a higher prevalence of Low-grade Squamous Intraepithelial Lesion (LSIL) in indigenous women. Peaks were observed in indigenous under 25, 35 to 39, 45 to 49, and 60 to 64. The prevalence of High-grade Squamous Intraepithelial Lesion or more severe (HSIL+) was low in both groups in women younger than 25. The indigenous HSIL+ prevalence curve showed a rapid increase, reaching peaks in women from 25 to 34 years, following a slight decrease and a plateau. In screening tests, HSIL+ was more prevalent in indigenous from 25 to 39 (PR 4.0,2.3;6.8) and 40 to 64 (PR 3.8,1.6;9.0). In indigenous, the PR of HSIL+ results in screening tests over 1st tests showed no screening effect in all age groups. In non-indigenous, there was a significant effect toward protection in the age groups over 25. CONCLUSION: This screening study of indigenous women from diverse ethnicities showed a higher prevalence of cytological LSIL and HSIl+ than in non-indigenous women. The protective screening effect in reducing HSIL+ prevalence was not observed in indigenous.

RESUMO

Objective: To evaluate whether integrating breast and cervical cancer screening in Rwanda's Women's Cancer Early Detection Program led to early breast cancer diagnoses in asymptomatic women. Methods: Launched in three districts in 2018-2019, the early detection programme offered clinical breast examination screening for all women receiving cervical cancer screening, and diagnostic breast examination for women with breast cancer symptoms. Women with abnormal breast examinations were referred to district hospitals and then to referral hospitals if needed. We examined how often clinics were held, patient volumes and number of referrals. We also examined intervals between referrals and visits to the next care level and, among women diagnosed with cancer, their initial reasons for seeking care. Findings: Health centres held clinics > 68% of the weeks. Overall, 9763 women received cervical cancer screening and clinical breast examination and 7616 received breast examination alone. Of 585 women referred from health centres, 436 (74.5%) visited the district hospital after a median of 9 days (interquartile range, IQR: 3-19). Of 200 women referred to referral hospitals, 179 (89.5%) attended after a median of 11 days (IQR: 4-18). Of 29 women diagnosed with breast cancer, 19 were ≥ 50 years and 23 had stage III or stage IV disease. All women with breast cancer whose reasons for seeking care were known (23 women) had experienced breast cancer symptoms. Conclusion: In the short-term, integrating clinical breast examination with cervical cancer screening was not associated with detection of early-stage breast cancer among asymptomatic women. Priority should be given to encouraging women to seek timely care for symptoms.

RESUMO

BACKGROUND: Globally, cervical cancer is the fourth most commonly diagnosed cancer amongst women, and it is especially common in low- and middle-income countries (LMICs). The aim of the study was to determine the current patterns and characteristics of CC management in Zimbabwe in the HIV pandemic era, including the knowledge, attitude and practice of patience. METHODS: The study was a mixed method which incorporated a cross-sectional survey of 408 CC patients which was conducted from October 2019 to September 2020 using an interviewer administered paper questionnaire. The study was conducted at Parirenyatwa hospital, the only cancer treating public health facility in Harare, Zimbabwe. Differences in study outcome by categorical variables were assessed using the Person Chi-square (χ2) test. Odds ratios (unadjusted and adjusted) and 95%CIs for potential risk factors associated with the outcome were estimated using logistic regression model. RESULTS: From a total of 408 CC patients recruited into the study no prevention mechanism was available or known to these patients and only 13% knew that CC is caused by Human papillomavirus. Only 87 (21%) had ever been screened for CC and 83 (97%) of those who had been screened had the visual inspection with acetic acid procedure done. Prevention (screening uptake) is statistically high among the educated (with secondary education OR = 9.497, 95%CI: 2.349-38.390; with tertiary OR = 59.381, 95%CI: 11.937-295.380). Late presentation varied statistically significantly with marital status (high among the divorced, OR = 2.866; 95% CI: 1.549-5.305 and widowed OR = 1.997; 95% CI: 1.112-3.587), was low among the educated (Tertiary OR = .393; 95% CI: .166-.934), low among those living in the rural (OR = .613; 95% CI: .375-.987), high among those with higher parity OR = 1.294; 95% CI: 1.163-1.439). Less than 1% of the patients had surgery done as a means of treatment. Radiotherapy was administered to 350 (86%) of the patients compared to chemotherapy administered to 155 (38%). A total of 350 (86%) have failed to take medication due to its unavailability, while 344 (85%) missed taking medication due to unaffordability. Complementary and alternative medicines were utilized by 235 (58%). Majority, 278 (68%) were HIV positive, mainly pronounced within age (36-49 years OR = 12.673; 95% CI: 2.110-76.137), among those with higher education (secondary education OR = 4.981; 95%CI: 1.394-17.802 and in those with no co-morbidities (893.956; 95%CI: 129.611-6165.810). CONCLUSION: CC management was inadequate from prevention, screening, diagnosis, treatment and palliative care hence there is need to improve CC management in Zimbabwe if morbidity and mortality are to be reduced to acceptable levels. Education helped improve prevention, but reduces chances of diagnosis, working as a doubled edged sword in CC management Prevention was high among the educated. Those in rural areas experience poor CC management. It should be noted that general education is good; however it must be complimented by CC awareness to improve CC management outcomes holistically. Cervical cancer management services need to be decentralized so that those in rural areas have easy access. Given that those with co-morbidities and high parity have better CC management, CC services need to be tied to co-morbidity and antenatal/post-natal care and management services.

RESUMO

OBJECTIVES: Since 2006, the US human papillomavirus (HPV) vaccination program has led to decreases in HPV infections caused by high-risk vaccine-targeted HPV types (HPV 16/18). We assessed differences in high-risk HPV prevalence by cervical cytology result among 20- to 24-year-old persons participating in routine cervical cancer screening in 2015-2017 compared with 2007. MATERIALS AND METHODS: Residual routine cervical cancer screening specimens were collected from 20- to 24-year-old members of 2 integrated healthcare delivery systems as part of a cross-sectional study and were tested for 37 HPV types. Cytology results and vaccination status (≥1 dose) were extracted from medical records. Cytology categories were normal, atypical squamous cells of undefined significance, low-grade squamous intraepithelial lesions (SIL), or high-grade SIL/atypical squamous cells cannot exclude high-grade SIL. Prevalences of HPV categories (HPV 16/18, HPV 31/33/45/52/58, HPV 35/39/51/56/59/66/68) were estimated by cytology result for 2007 and 2015-2017. RESULTS: Specimens from 2007 (n = 4046) were from unvaccinated participants; 4574 of 8442 specimens (54.2%) from 2015-2017 were from vaccinated participants. Overall, HPV 16/18 positivity was lower in 2015-2017 compared with 2007 in all groups: high-grade SIL/atypical squamous cells cannot exclude high-grade SIL, 16.0% vs 69.2%; low-grade SIL, 5.4% vs 40.1%; atypical squamous cells of undefined significance, 5.0% vs 25.6%; and normal, 1.3% vs 8.1%. Human papillomavirus 31/33/45/52/58 prevalence was stable for all cytology groups; HPV 35/39/51/56/59/66/68 prevalence increased among low-grade SIL specimens (53.9% to 65.2%) but remained stable in other groups. CONCLUSIONS: Prevalence of vaccine-targeted high-risk HPV types 16/18 was dramatically lower in 2015-2017 than 2007 across all cytology result groups while prevalence of other high-risk HPV types was mainly stable, supporting vaccine impact with no evidence of type replacement.

RESUMO

OBJECTIVES: Cervical cancer is frequently diagnosed in older women, but few studies have focused on cervical cancer in this specific population. The objectives of this study were to provide an overview of the demographic profile and therapeutic care of women with cervical cancer, and to identify whether age is a prognostic factor. STUDY DESIGN: Retrospective population-based study from a gynecological cancer registry in a French Regional University Hospital and Comprehensive Cancer Center. 292 women diagnosed with cervical cancer between January 1, 2005, and December 31, 2015, were included. They were classified into younger women (YW), that is, under 70 years of age (N = 228), and older women (OW), that is, aged 70 years or more (N = 64). MAIN OUTCOME MEASURES: The primary outcome was overall survival (OS). Cox proportional hazards models were developed to assess the impact of age on OS. RESULTS: Compared with YW, larger proportions of OW had comorbidities (14% vs 7% with a score ≥ 2 on the Charlson Comorbidity Index, P <0.001) and more advanced tumors (37.3% vs 19.7% with FIGO IV, P <0.001); the OW group had a lower treatment rate (81.3% vs 95.6%, P <0.001), and a smaller proportion had undergone surgery (37.5% vs 81.7%, P<.001) but a larger proportion had radiotherapy (67.2% vs 49.6%, P = .01). One-year, 5-year and 10-year OS rates were: 91.6%, 74.1% and 63.9% for YW, and 69.9%, 36.4% and 12.3% for OW, respectively (P <0.001). The hazard ratio for death was twice as high in OW compared with YW with cervical cancer (HR = 2.19 [1.41 - 3.40], P <0.001), independently of FIGO stage, histology, and comorbidities. CONCLUSIONS: The prognosis for cervical cancer depends on age. Screening with the G8 tool followed by a comprehensive geriatric assessment could lead to more suitable treatment being offered to older patients.

RESUMO

Although the effects of coffee consumption and physical exercise on the risk of cancer have been suggested, their interactions have not been investigated. The present cross-sectional study aimed to investigate the correlation of coffee consumption and physical exercise with cancer. Participants ≥40 years old in the Korean Genome and Epidemiology Study 2004-2016 were included (n = 162,220). Histories of gastric cancer, hepatic cancer, colon cancer, breast cancer, uterine cervix cancer, lung cancer, thyroid cancer, prostate cancer, and bladder cancer were analyzed according to the coffee consumption groups using logistic regression models. The odds among individuals in the >60 cups/month coffee group were lower for gastric cancer (adjusted odds ratio (aOR) = 0.80 (95% confidence intervals = 0.65-0.98)), hepatic cancer (0.32 (0.18-0.58)), colon cancer (0.53 (0.39-0.72)), breast cancer (0.56 (0.45-0.70)), and thyroid cancer (0.71 (0.59-0.85)) than for individuals in the no coffee group. Physical exercise of ≥150 min/week was correlated with higher odds for gastric cancer (1.18 (1.03-1.36)), colon cancer (1.52 (1.26-1.83)), breast cancer (1.53 (1.35-1.74)), thyroid cancer (1.42 (1.27-1.59)), and prostate cancer (1.61 (1.13-2.28)) compared to no exercise. Coffee consumption and physical exercise showed an interaction in thyroid cancer (p = 0.002). Coffee consumption was related to a decreased risk of gastric cancer, hepatic cancer, colon cancer, breast cancer, and thyroid cancer in the adult population. Physical exercise was positively correlated with gastric cancer, colon cancer, breast cancer, thyroid cancer, and prostate cancer.

RESUMO

Cancer incidence is rising in low- and especially middle-income countries (MIC), driven primarily by four high-burden cancers (breast, cervix, lung, colorectal). By 2030, more than two-thirds of all cancer deaths will occur in MICs. Prevention and early detection are required alongside efforts to improve access to cancer treatment. Successful strategies for decreasing cancer mortality in high-income countries are not always effective, feasible or affordable in other countries. In this review, we evaluate strategies for prevention and early detection of breast, cervix, lung, and colorectal cancers, focusing on modifiable risk factors and high-risk subpopulations. Tobacco taxation, human papilloma virus vaccination, cervical cancer screen-and-treat strategies, and efforts to reduce patient and health system-related delays in the early detection of breast and colorectal cancer represent the highest yield strategies for advancing cancer control in many MICs. An initial focus on high-risk populations is appropriate, with increasing population coverage as resources allow. These strategies can deliver significant cancer mortality gains, and serve as a foundation from which countries can develop comprehensive cancer control programs. Investment in national cancer surveillance infrastructure is needed; the absence of national cancer data to identify at-risk groups remains a barrier to the development of context-specific cancer control strategies.

RESUMO

BACKGROUND: Cervical cancer is the leading cause of female cancer mortality in Botswana with the majority of cervical cancer patients presenting with late-stage disease. The identification of factors associated with late-stage disease could reduce the cervical cancer burden. This study aims to identify potential patient level clinical and sociodemographic factors associated with a late-stage diagnosis of cervical cancer in Botswana in order to help inform future interventions at the community and individual levels to decrease cervical cancer morbidity and mortality. RESULTS: There were 984 women diagnosed with cervical cancer from January 2015 to March 2020 at two tertiary hospitals in Gaborone, Botswana. Four hundred forty women (44.7%) presented with late-stage cervical cancer, and 674 women (69.7%) were living with HIV. The mean age at diagnosis was 50.5 years. The association between late-stage (III/IV) cervical cancer at diagnosis and patient clinical and sociodemographic factors was evaluated using multivariable logistic regression with multiple imputation. Women who reported undergoing cervical cancer screening had lower odds of late-stage disease at diagnosis (OR: 0.63, 95% CI 0.47-0.84) compared to those who did not report screening. Women who had never been married had increased odds of late-stage disease at diagnosis (OR: 1.35, 95% CI 1.02-1.86) compared to women who had been married. Women with abnormal vaginal bleeding had higher odds of late-stage disease at diagnosis (OR: 2.32, 95% CI 1.70-3.16) compared to those without abnormal vaginal bleeding. HIV was not associated with a diagnosis of late-stage cervical cancer. Rural women who consulted a traditional healer had increased odds of late-stage disease at diagnosis compared to rural women who had never consulted a traditional healer (OR: 1.61, 95% CI 1.02-2.55). CONCLUSION: Increasing education and awareness among women, regardless of their HIV status, and among providers, including traditional healers, about the benefits of cervical cancer screening and about the importance of seeking prompt medical care for abnormal vaginal bleeding, while also developing support systems for unmarried women, may help reduce cervical cancer morbidity and mortality in Botswana.

RESUMO

OBJECTIVE: This study aimed to assess the effect that race and socioeconomic factors have on the provision of care to cervical cancer patients based on National Comprehensive Cancer Network (NCCN) recommended treatment guidelines. MATERIALS AND METHODS: To do this, we completed a retrospective cohort study using the American College of Surgeon's Nation Cancer Database from 2004 to 2016. We identified all reported cases of cervical cancer in that period. Two cohorts were created using self-reported racial demographic data, Hispanic- and White, non-Hispanic-identified patients. Our primary outcome variables were adherence to NCCN-recommended treatment and 5-year overall survival. Adherence to NCCN-recommended treatment was determined by the provision of surgical and/or radiation and/or chemotherapy treatment based on the clinical stage at time of diagnosis and the presence or absence of lymphovascular space invasion. We used bivariate analyses to compare baseline characteristics between the 2 cohorts, multivariable logistic regression to identify independent predictors of 5-year survival, and Cox proportional hazards models to compute survival by group. RESULTS: The difference in NCCN-adherent care between the 2 cohorts was found to be not statistically significant (p = .880). A log rank (Mantel-Cox) χ2 test showed that there was a statistically significant difference between the 2 groups in overall survival with the Hispanic-identified patients living longer (p < .001). Our study is limited by the effect large databases confer on finding statistical significance. CONCLUSIONS: Hispanic-identified women with cervical cancer receive NCCN-compliant care and live longer than their White, non-Hispanic counterparts.

RESUMO

OBJECTIVES: HPV self-sampling is an option for cervical screening. The aim of this randomised study was to investigate the compliance, prevalence of HPV, and prevalence of severe dysplasia in a vaginal self-sampling group in comparison to cervical samples collected by midwives (control arm). The hypothesis was that there would be no difference between vaginal self-sampling and cervical sampling to find high-grade cervical dysplasia or cancer. METHODS: Vaginal HPV self-sampling kits were sent by regular mail to 14 765 randomly selected women aged 30-64 years old in the screening programme. HPV-positive women were invited for a follow-up examination by their midwife in which they provided a cervical sample for cytological and HPV co-testing. The control arm consisted of 14 839 women who met the same inclusion criteria and were invited to have cervical sampling by midwives for primary HPV screening. All HPV samples were analysed by the Aptima HPV assay (Hologic Inc.). MAIN RESULTS: The participation rate was 33.5% in the self-sampling arm and 47.5% in the cervical sampling arm, (P < 0.0001). HPV was detected in 17.1% (95% confidence interval (CI), 16.1-18.23%) in the self-sampling arm and 4.5% (95% CI, 4.0-5.0%) in the cervical sampling arm. Histological, severe dysplasia was observed among 0.48% (95% CI, 0.3-0.72%) and 0.47% (95% CI, 0.3-0.66%) of the self-sampling and the cervical sampling groups, respectively. CONCLUSION: The self-sampling approach detects a similar proportion of severe dysplasia as regular screening. Thus, our study indicates that self-sampling could replace primary HPV screening of cervical samples.

RESUMO

Population-based cancer registries (PBCR) are vital to the assessment of the cancer burden and in monitoring and evaluating national progress in cervical cancer surveillance and control. Yet the level of their development in countries exhibiting the highest cervical cancer incidence rates is suboptimal, and requires considerable investment if they are to document the impact of WHO global initiative to eliminate cervical cancer as a public health problem. As a starting point we propose a comprehensive cancer surveillance framework, positioning PBCR in relation to other health information systems that are required across the cancer control continuum. The key concepts of PBCR are revisited and their role in providing a situation analysis of the scale and profile of the cancer-specific incidence and survival, and their evolution over time is illustrated with specific examples. Linking cervical cancer data to screening and immunization information systems enables the development of a comprehensive set of measures capable of assessing the short- and long-term achievements and impact of the initiative. Such data form the basis of national and global estimates of the cancer burden and permit comparisons across countries, facilitating decision-making or triggering cancer control action. The initiation and sustainable development of PBCR must be an early step in the scale-up of cervical cancer control activities as a means to ensure progress is successfully monitored and appraised.

RESUMO

This article addresses human papillomavirus (HPV) infection, this being one of the topics covered by the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health. The Protocol and Guidelines have been developed based on scientific evidence and validated in discussions with specialists. This article presents epidemiological and clinical aspects, as well as guidelines for health service managers and health workers about diagnosing and treating people with papillomavirus infection. This theme is an important public health problem, since it is the most prevalent sexually transmitted infection in the world, capable of triggering the oncogenic process of cervical cancer, as well as the possibility anogenital warts occurring. Important information is presented for gaining knowledge about HPV, as well as action strategies for infection prevention and control, provision of quality care and effective treatment of the disease.

RESUMO

BACKGROUND: Cervical cancer (CC) is the most common female cancer in many countries of sub-Saharan Africa (SSA). We assessed treatment guideline adherence and its association with overall survival (OS). METHODS: Our observational study covered nine population-based cancer registries in eight countries: Benin, Ethiopia, Ivory Coast, Kenya, Mali, Mozambique, Uganda, and Zimbabwe. Random samples of 44-125 patients diagnosed from 2010 to 2016 were selected in each. Cancer-directed therapy (CDT) was evaluated for degree of adherence to National Comprehensive Cancer Network (U.S.) Guidelines. RESULTS: Of 632 patients, 15.8% received CDT with curative potential: 5.2% guideline-adherent, 2.4% with minor deviations, and 8.2% with major deviations. CDT was not documented or was without curative potential in 22%; 15.7% were diagnosed with International Federation of Gynecology and Obstetrics (FIGO) stage IV disease. Adherence was not assessed in 46.9% (no stage or follow-up documented, 11.9%, or records not traced, 35.1%). The largest share of guideline-adherent CDT was observed in Nairobi (49%) and the smallest in Maputo (4%). In patients with FIGO stage I-III disease (n = 190), minor and major guideline deviations were associated with impaired OS (hazard rate ratio [HRR], 1.73; 95% confidence interval [CI], 0.36-8.37; HRR, 1.97; CI, 0.59-6.56, respectively). CDT without curative potential (HRR, 3.88; CI, 1.19-12.71) and no CDT (HRR, 9.43; CI, 3.03-29.33) showed substantially worse survival. CONCLUSION: We found that only one in six patients with cervical cancer in SSA received CDT with curative potential. At least one-fifth and possibly up to two-thirds of women never accessed CDT, despite curable disease, resulting in impaired OS. Investments into more radiotherapy, chemotherapy, and surgical training could change the fatal outcomes of many patients. IMPLICATIONS FOR PRACTICE: Despite evidence-based interventions including guideline-adherent treatment for cervical cancer (CC), there is huge disparity in survival across the globe. This comprehensive multinational population-based registry study aimed to assess the status quo of presentation, treatment guideline adherence, and survival in eight countries. Patients across sub-Saharan Africa present in late stages, and treatment guideline adherence is remarkably low. Both factors were associated with unfavorable survival. This report warns about the inability of most women with cervical cancer in sub-Saharan Africa to access timely and high-quality diagnostic and treatment services, serving as guidance to institutions and policy makers. With regard to clinical practice, there might be cancer-directed treatment options that, although not fully guideline adherent, have relevant survival benefit. Others should perhaps not be chosen even under resource-constrained circumstances.

RESUMO

PURPOSE: Glassy cell carcinoma (GCC) of the uterine cervix is a rare entity. This study aims at describing the clinical characteristics and outcomes of cervical GCC patients treated in a comprehensive cancer center. MATERIAL AND METHODS: We retrospectively reported patients and tumors characteristics, therapeutic management, overall survival (OS), progression-free progression (PFS), relapse rates, and toxicities. RESULTS: Between 1994 and 2014, 55 patients were treated with curative intent. The median age at diagnosis was 41 years (range, 20-68). Among 22 patients with early stage tumors (IA2-IB1-IIA1), 17 had preoperative brachytherapy, followed by radical hysterectomy. Among 33 patients with locally advanced disease (≥IB2), 32 underwent chemoradiation±brachytherapy boost. After a median follow-up of 5.4 years (range, 0.15-21.7 years), 18/55 (33%) patients experienced tumor relapse. Local recurrence occurred in 2/22 (9%) patients with early disease (treated with upfront surgery) and in 3/32 (9%) patients with locally advanced disease. Most frequent relapses were distant, occurring in a total of 11/55 patients (20%). PFS rates at 5-year were 86.4% (95% CI: 63.4-95.4) for early stage versus 75.9% (95% CI: 55.2-89.2) for locally advanced stages, respectively (P=0.18). CONCLUSION: Large cohort data are warranted to guide the optimal management of GCC. From this retrospective analysis, a multimodal approach yielded to good disease control in early stages tumors. Given the high-risk of distant failure, consideration should be given to adjuvant chemotherapy in locally advanced disease.

RESUMO

BACKGROUND: New guidelines for managing cervical precancer among women in the United States use risk directly to guide clinical actions for individuals who are being screened. These risk-based management guidelines have previously only been based on risks from a large integrated healthcare system. We present here data representative of women of low income without continuous insurance coverage to inform the 2019 guidelines and ensure applicability. OBJECTIVE: We examined the risks of high-grade precancer after human papillomavirus and cytology tests in underserved women and assessed the applicability of the 2019 guidelines to this population. STUDY DESIGN: We examined cervical cancer screening and follow-up data among 363,546 women enrolled in the Centers for Disease Control and Prevention's National Breast and Cervical Cancer Early Detection Program from 2009 to 2017. We estimated the immediate (prevalent) risks of cervical intraepithelial lesion grade 3 or cancer by using prevalence-incidence mixture models. Risks were estimated for each combination of human papillomavirus and cytology result and were stratified by screening history. We compared these risks with published estimates used in new risk-based management guidelines. RESULTS: Women who were up-to-date with their screening, defined as being screened with cytology within the past 5 years, had immediate risks of cervical intraepithelial neoplasia grade 3 or higher similar to that of women at Kaiser Permanente Northern California, whose data were used to develop the management guidelines. However, women in the Centers for Disease Control and Prevention's National Breast and Cervical Cancer Early Detection Program had greater immediate risks if they were never screened or not up-to-date with their screening. CONCLUSION: New cervical risk-based management guidelines are applicable for underinsured and uninsured women with a low income in the United States who are up-to-date with their screening. The increased risk observed here among women who received human papillomavirus-positive, high-grade cytology results, who were never screened, or who were not up-to-date with their cervical cancer screening, led to a recommendation in the management guidelines for immediate treatment among these women.

RESUMO

This study used the Korean National Health Insurance (NHI) claims database from 2011 to 2017 to estimate the incidence and the incidence-based cost of cervical cancer and carcinoma in situ of cervix uteri (CIS) in Korea. The primary outcome was the direct medical cost per patient not diagnosed with cervical cancer (C53) or CIS (D06) 2 years prior to the index date in the first year after diagnosis. A regression analysis was conducted to adjust for relevant covariates. The incidence of cervical cancer tended to decrease from 2013 to 2016, while that of CIS increased. In particular, the incidence rate of CIS in women in their 20 s and 30 s increased by 56.8% and 28.4%, respectively, from 2013 to 2016. The incidence-based cost of cervical cancer and CIS was USD 13,058 and USD 2695 in 2016, respectively, which increased from 2013. Multivariate regression analysis suggested that age was the most influential variable of the cost in both patient groups, and the cost was highest in those aged over 60, i.e., the medical cost was significantly lower in younger women than their older counterparts. These findings suggest that targeting younger women in cervical cancer prevention is a reasonable option from both economic and public health perspectives.

RESUMO

OBJECTIVES: Cervical cancer is a leading cause of cancer-related mortality in women in China. This analysis is a quantitative evidence synthesis pooling information about each cervical cancer risk factor. METHODS: A meta-model was developed to estimate the risk of cervical cancer for a woman aged 18-85 years in Mainland China based on her risk profile at the time of assessment. The meta-model was built using findings of a systematic literature review that identified 21 case-control studies reporting data on 105 groups of cervical cancer risk factors in Chinese women. Extracted risk factors were ranked, and 17 were selected by Chinese clinical experts for inclusion in the meta-model. Risk equations were developed for each selected study. Predicted risks for each study were dependent on the risk profile under consideration and study-specific risks were pooled to an overall risk estimate using a random-effects meta-analysis. Sensitivity analysis was conducted using 100 artificial patient profiles (in the absence of patient data). RESULTS: Predicted risks for the 100 profiles suggested that the model had good face validity and could differentiate between high and non-high cervical cancer risk profiles. CONCLUSION: This innovative meta-model approach assesses cervical cancer risk in Chinese women from a holistic perspective and could be adapted for other diseases and settings.

RESUMO

Cervical cancer is the fourth most frequently diagnosed cancer and the fourth leading cause of cancer death in women. The discrepancy in cervical cancer incidence and mortality between developed and developing nations has become increasingly apparent with 84% of the incidence and 88% of the mortality of cervical cancer occurring in low income countries. Access to comprehensive cancer care is a challenge and in particular the radiotherapy facilities. The radiotherapy infrastructure requirement is grossly inadequate with only 30% of the needs available and is even worst in LIC's with only 3% facilities. Additionally, lack of brachytherapy facilities and expertise in LIC's and LMIC's compounds the issue further. Even with continued HPV vaccination programs, there will still be a substantial burden of cervical cancer patients for treatment. Introspection and review in international and national policies, augmentation of (i) infrastructure - affordable & sustainable, (ii) manpower and rigorous training in accessible regions would be vital. International and National collaborative efforts among global organizations and societies, periodic peer reviews, resource stratified treatment guidelines and research, and health education would contribute further to women health. The amalgamation of palliative and hospice care services and radiotherapy facilities seamlessly would be a major step for comprehensive management of cervical cancer patients.
