Clinicopathological Factors Affecting Breast Cancer Survival in Jamaican Women: A Retrospective Review. J Racial Ethn Health Disparities 2023; 10:844-858. [PMID: 35266120 DOI: 10.1007/s40615-022-01273-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Revised: 02/21/2022] [Accepted: 02/22/2022] [Indexed: 10/18/2022]
Abstract
OBJECTIVE Breast cancer is the leading cause of cancer affecting women worldwide. The survival rate is primarily affected by the stage of the disease and several other demographic and clinicopathological factors. METHODS This study is a retrospective cohort study of female patients of the University Hospital of the West Indies diagnosed with breast cancer between 2011 and 2016. The age, tumor size, SBR/Nottingham grade, tumor histologic subtype, tumor molecular subtype, and survival status of the cohort on November 1, 2019, were determined. The data were summarized. Survival across each variable was compared using univariate log-rank tests, Cox proportional hazard models, and crude and adjusted models. A second wave analysis was performed excluding patients whose survival status was presumed. RESULTS A total of 503 patients were analyzed. The overall survival rate at 1, 3, and 5 years were 96.4%, 84.9%, and 79.0%, respectively, for the entire cohort. The molecular subtype was the most significant clinicopathological factor affecting overall survival. A younger age < 40 years, higher histologic grade, estrogen receptor-negative breast cancers, invasive ductal type breast cancers, and T1 lesions were associated with poorer survival outcomes at 5 years. The findings were reproduced after a second wave analysis excluding patients who were presumed alive was applied. CONCLUSIONS Breast cancer overall survival in Jamaica is consistent with that of other developing countries in the literature. This study is an important contribution to the growing body of literature available and aids to the overall understanding of the behavior of breast cancer locally.

Abstract
OBJECTIVES This study aims to estimate the proportion of lung cancer cases and deaths attributable to tobacco smoking in Portugal in 2018, complemented by trends in incidence and mortality, by sex and region. DESIGN Cancer cases for 1998-2011 and cancer deaths for 1991-2018 were obtained from population-based registries and Statistics Portugal, respectively. We projected cases for 2018 and used reported deaths for the same year to estimate, using Peto's method, the number and proportion of lung cancer cases and deaths caused by tobacco smoking in 2018. We calculated the age-adjusted incidence and mortality rates in each year of diagnosis and death. We fitted a joinpoint regression to the observed data to estimate the annual percentage change (APC) in the rates. SETTING Portugal. RESULTS In 2018, an estimated 3859 cases and 3192 deaths from lung cancer were attributable to tobacco smoking in Portugal, with men presenting a population attributable fraction (PAF) of 82.6% (n=3064) for incidence and 84.1% (n=2749) for mortality, while in women those values were 51.0% (n=795) and 42.7% (n=443), respectively. In both sexes and metrics, the Azores were the region with the highest PAF and the Centre with the lowest. During 1998-2011, the APC for incidence ranged from 0.6% to 3.0% in men and 3.6% to 7.9% in women, depending on region, with mortality presenting a similar pattern between sexes. CONCLUSION Exposure to tobacco smoking has accounted for most of the lung cancer cases and deaths estimated in Portugal in 2018. Differential patterns of tobacco consumption across the country, varying implementation of primary prevention programmes and differences in personal cancer awareness may have contributed to the disparities observed. Primary prevention of lung cancer remains a public health priority, particularly among women.

Abstract
PURPOSE This study sought to provide a detailed analysis of breast cancer–specific mortality in Jamaica on the basis of reported deaths between 2010 and 2014. METHODS A cross-sectional study was done to analyze breast cancer–specific mortality data from the Registrar General’s Department, the statutory body responsible for registering all deaths across Jamaica. RESULTS A total of 1,634 breast cancer–related deaths were documented among Jamaican women between 2010 and 2014, which accounted for 24% of all female cancer deaths. The age-standardized breast cancer mortality rate increased from 21.8 per 100,000 in 2010 to 28 per 100,000 in 2014 for the total female population. The overall difference in breast cancer mortality rates between the 2014 and 2010 rates was not statistically significant (P = .114). Analysis of the year-by-year trend reflected by the annual percentage of change did show, however, a statistically significant increasing trend in breast cancer mortality (P = .028). Mortality rates varied by age, with statistically significant annual increases observed in the 35-44–, 65-74–, and ≥ 75-year age groups (P = .04, .03, and .01, respectively). CONCLUSION Breast cancer remains the leading cause of cancer-related death among Jamaican women. Despite global advances in breast cancer screening and management, breast cancer remains a major public health challenge and represents a public health priority in Jamaica. The increasing breast cancer–specific mortality in Jamaica over the 5-year period contrasts with decreasing mortality rates among US women with breast cancer. This study highlights the critical need to address the implementation of a national organized breast cancer screening program in Jamaica and to focus future research efforts on the biology of breast cancer, especially among young Jamaican women.

Abstract
Background & Objective: Most colorectal cancers (CRCs) arise from adenomatous polyps, and clinical management of this type of polyp is highly dependent on the reliability and validity of the pathological diagnosis. The aim of this study was to examine the interobserver agreement of five pathologists in assessing dysplasia in adenomatous polyps. Methods: In this study, a total of 146 adenomatous polyps of patients undergoing colonoscopy were selected from hospitals of Shahid Beheshti University of Medical Sciences, Tehran, Iran between 2017 and 2018. Five pathologists independently classified adenomatous polyps according to histologic type, nuclear pseudostratification, mitotic activity, nuclear polarity, nuclear pleomorphism, nuclear shape, nucleolus, chromatin pattern, cytology grade, architectural features, dysplasia, and final diagnosis. The overall kappa statistic (k) was used to assess agreement among pathologists. Results: The mean age of the patients was 62.06 ± 13.06 (mean ± SD) with a male-to-female ratio of 2.2:1. The most common site of resection was the sigmoid colon (28.1%). The highest agreement was found for dysplasia grade (k=0.415) and histologic type (k=0.401), whereas the lowest agreement was found for mitotic activity (k=0.185), nuclear shape (k=0.187), and nucleolus (k=0.196). Conclusion: Our findings indicate that agreement among pathologists in assessing dysplasia in adenomatous polyps is within fair to moderate levels of agreement. Therefore, there is a vital need to better clarify the current diagnostic criteria.

Abstract
Cervical cancer is the fourth most frequently occurring cancer in women around the world and can affect them during their reproductive years. Since the development of the Papanicolaou (Pap) test, screening has been essential in identifying cervical cancer at a treatable stage. With the identification of the human papillomavirus (HPV) as the causative agent of essentially all cervical cancer cases, HPV molecular screening tests and HPV vaccines for primary prevention against the virus have been developed. Accordingly, comparative studies were designed to assess the performance of cervical cancer screening methods in order to devise the best screening strategy possible. This review critically assesses the current cervical cancer screening methods as well as the implementation of HPV vaccination in Europe. The most recent European Guidelines and recommendations for organized population-based programs with HPV testing as the primary screening method are also presented. Lastly, the current landscape of cervical cancer screening programs is assessed for both European Union member states and some associated countries, in regard to the transition towards population-based screening programs with primary HPV testing.

Abstract
INTRODUCTION Understanding the patterns of mammography use and monitoring changes in use are essential to improving national health policy for breast cancer control. We aimed to describe the use of mammography in Portugal and to identify the determinants of its nonuse and underuse by examining data from the National Health Survey 2014. METHODS We analyzed data on 8,758 women aged 30 years or older. We defined women at an eligible age for mammography as women aged 45 to 69. Women who reported a previous mammography test were classified as ever-users and grouped according to time since the most recent test. We computed the prevalence of mammography use, and we used Poisson regression models to obtain age-adjusted and education-adjusted prevalence ratios and 95% confidence intervals. RESULTS The overall prevalence of mammography use was 80.0%, whereas nonuse was 20.0% and underuse 27.3% among users. The prevalence of nonuse and underuse were lower and associations with sociodemographic characteristics, use of health care services, and behavioral factors were stronger among women aged 45 to 69 than among women aged 30 to 44 and women aged 70 or older. The prevalence of mammography use was generally higher in the northern areas of Portugal than in southern areas and varied by marital status, educational level, and household size. A more frequent use of health care services and healthier behaviors were associated with lower prevalences of both nonuse and underuse. CONCLUSION This study illustrates inequalities in mammography use and provides useful information for better allocation of resources in breast cancer screening.

Abstract
BACKGROUND Cancer screening has contributed to downward trends in cancer mortality, but is also associated with adverse effects, which highlights the importance of promoting the participation based on informed decisions. OBJECTIVES We aimed to describe the use of cancer screening (either in organized programmes or as opportunistic screening), awareness of organized programmes and perception of its potential benefits and adverse effects, depicting possible sex differences. DESIGN AND METHODS We evaluated 1624 Portuguese-speaking dwellers, aged between 16 and 79 years, through face-to-face interviews. To quantify sex differences, adjusted prevalence ratios and respective 95% confidence intervals were computed using Poisson regression. RESULTS Among eligible age groups, the lifetime prevalence of screening for breast and cervical cancers was 89.8 and 71.9%, respectively. The prevalence was 23.7% for colorectal cancer and no significant sex differences were observed. Prostate cancer screening was reported by 63.8% of men. Over half of the participants referred that cancers such as prostate, skin, lung and stomach should be screened for, in addition to those for which organized programmes are recommended. Reassurance by negative results was identified as the main potential benefit of screening by nearly one-third of men and women. Anxiety while waiting for results was the most mentioned potential adverse effect (60.4%); men refer less often this and financial costs, although statistical significance of these results was borderline. CONCLUSIONS This study provides a benchmark to plan and monitor the effects of awareness-raising interventions, as well as for international comparisons across countries with different cancer prevention and control structures.

The magnitude and characteristics of the population of cancer survivors: using population-based estimates of cancer prevalence to inform service planning for survivorship care. BMC Cancer 2014; 14:767. [PMID: 25319534 PMCID: PMC4216835 DOI: 10.1186/1471-2407-14-767] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2014] [Accepted: 09/24/2014] [Indexed: 02/08/2023] Open
Abstract
Background Rising cancer incidence and survival mean that the number of cancer survivors is growing. Accumulating evidence suggests many survivors have long-term medical and supportive care needs, and that these needs vary by survivors’ socio-demographic and clinical characteristics. To illustrate how cancer registry data may be useful in survivorship care service planning, we generated population-based estimates of cancer prevalence in Ireland and described socio-demographic and clinical characteristics of the survivor population. Methods Details of people diagnosed with invasive cancer (ICD10 C00-C96) during 1994–2011, and who were still alive on 31/12/2011, were abstracted from the National Cancer Registry, and tabulated by cancer site, sex, current age, marital status, initial treatment, and time since diagnosis. Associations were investigated using chi-square tests. Results After excluding non-melanoma skin cancers, 17-year cancer prevalence in Ireland was 112,610 (females: 58,054 (52%) males: 54,556 (48%)). The four most prevalent cancers among females were breast (26,066), colorectum (6,598), melanoma (4,593) and uterus (3,505) and among males were prostate (23,966), colorectum (8,207), lymphoma (3,236) and melanoma (2,774). At the end of 2011, 39% of female survivors were aged <60 and 35% were ≥70 compared to 25% and 46% of males (p < 0.001). More than half of survivors of bladder, colorectal and prostate cancer were ≥70. Cancers with the highest percentages of younger (<40) survivors were: testis (50%); leukaemia (females: 28%; males: 22%); cervix (20%); and lymphoma (females: 19%; males: 20%). Fewer female (57%) than male (64%) survivors were married but the percentage single was similar (17-18%). More female (25%) than male survivors (18%; p < 0.001) were ≥10 years from diagnosis. Overall, 69% of survivors had undergone cancer-directed surgery, and 39%, 32% and 18% had received radiotherapy, chemotherapy and hormone therapy, respectively. These frequencies were higher among females than males (surgery: 82%, 54%; radiotherapy: 42%, 35%; chemotherapy: 40%, 22%; hormone therapy: 23%, 13%). Conclusions These results reveal the socio-demographic and clinical heterogeneity of the survivor population, and highlight groups which may have specific medical and supportive care needs. These types of population-based estimates may help decision-makers, planners and service providers to develop follow-up and after-care services to effectively meet survivors’ needs.

Abstract
BACKGROUND Breast cancer is the most common cause of cancer mortality among European women. To reduce mortality risk, early detection through mammography screening is recommended from the age of 50 years onwards. Although timely initiation is crucial for cancer prognosis, the temporal dimension has largely been ignored in research. In cross-sectional research designs, it is not clear whether reported age differences reflect 'true' age effects and/or presumed period effects resulting from evolving knowledge and screening programmes. METHODS We use longitudinal data from the survey of Health, Ageing and Retirement (SHARELIFE, 2008), which enables to cast light on age differences by providing retrospective information on the age at which women commenced regular mammography screening. Moreover, the cross-national dimension of the SHARE permits framing the results within the context of nationally implemented screening programmes. By means of the Kaplan-Meier procedure, we examine age trajectories for five 10-year birth cohorts in 13 European countries (n = 13 324). RESULTS Birth cohorts show very similar age trajectories for each country. Along with the observation that large country differences and country-specific deviations coincide with screening programme characteristics, this suggests strong period effects related to implemented national screening programmes. CONCLUSION Age differences in mammography screening generally reflect the period effects of national screening policies. This leaves little room for economic theories about human health capital that leave out the institutional context of preventive health care provision.

Abstract
BACKGROUND Understanding the patterns of cervical cytology use in preventive care may provide useful information for an efficient transition from opportunistic screening to organized programmes. We aimed to identify the determinants of non-use and underuse of cervical cytology in Portuguese women. METHODS As part of the fourth National Health Survey (2005/2006), 2191 women aged between 25 and 64 years were evaluated. The previous use of cervical cytology was classified as never or ever, and, among the latter, those having performed the latest cytology testing >5 years before were considered to underuse cervical cytology. We assessed the determinants of non-use and underuse through age- and education-adjusted odds ratios (ORs) and corresponding 95% confidence intervals (95% CIs). RESULTS Overall, 23.5% of women had never used cervical cytology and 10.7% reported underuse. This prevalence increased with age and decreased with education and income. Compared with the national mean, the lowest risk of non-use and underuse was observed in Norte (non-use: OR = 0.31, 95% CI: 0.23-0.42; underuse: OR = 0.60, 95% CI: 0.40-0.91) and the highest in Alentejo (non-use: OR = 2.33, 95% CI: 1.78-3.06; underuse: OR = 2.37, 95% CI: 1.43-3.93). Women without a private health insurance (OR = 2.65, 95% CI: 1.29-5.47), who had no doctor appointments in the preceding 3 months (OR = 2.06, 95% CI: 1.22-3.48) and those who had never performed a mammography (OR = 17.78, 95% CI: 9.09-34.78) were more likely to have never performed a cervical cytology. CONCLUSION This study shows inequalities in the use of cervical cancer screening in Portugal and provides useful information for a better allocation of resources for cancer screening.

Abstract
BACKGROUND Cardiovascular diseases and cancer are jointly responsible for more than half all deaths in Portugal. They also share some important risk factors and act as mutual competing risks. We aimed firstly to describe time trends in death rates and years of life lost due to cardiovascular diseases and cancer in the Portuguese population from 1980 to 2010; and secondly to quantify the contribution of the variation in population and age structure, and age-independent "risk" by cardiovascular or oncological causes to the change in the corresponding number of deaths. METHODS We estimated the annual percent change in age-standardized mortality rates from cardiovascular diseases and cancer, in each sex. The specific contribution of demographic changes (due to changes in population size and in population age structure) and the variation in the age-independent "risk" of dying from the disease to the observed trends in the number of deaths was quantified using the tool RiskDiff. Years of life lost were computed using the Global Burden of Disease method. RESULTS Among men, the mortality rate from all cardiovascular diseases was more than two-fold higher than cancer mortality in 1980. However, three decades later mortality from cancer surpassed cardiovascular diseases. After 2005, the years of life lost from cancer were also higher than from cardiovascular diseases. Among women, despite the decrease in death rates, cardiovascular diseases remained the leading cause of death in 2010 and their absolute burden was higher than that of cancers across the whole period, mainly due to more events in older women. CONCLUSIONS In Portugal, the 20th century witnessed a dramatic decrease in the cardiovascular disease mortality and YLL, and the transition towards cancer. In more recent years, the highest burdens of disease came from cancers in men and from cardiovascular diseases in women.

Abstract
Cervical cancer is a leading cause of cancer death in women in developing countries. A key factor linked to the relatively high levels of cervical cancer in these populations is the lack of awareness and access to preventive methods. This study aimed to determine the level of awareness of cervical cancer and Papanicolaou test (Pap smear test) and factors associated with the utilization of Pap test among female civil servants in Jos. Data was obtained from female workers (n = 388) aged 18-65 years in a Nigerian Federal establishment. Participants were randomly approached and instructed to complete validated questionnaires. Data was analyzed using Chi-square, t-tests and logistic regression analysis to determine if there was an association between variables and identify any predictors of awareness and utilization of the Pap test. Cervical cancer and Pap smear test awareness was 50.9% and 38.6% respectively, with the media as the major source of information. Pap smear test utilization rate was 10.2%, with routine antenatal care (ANC) as the major reason for getting screened. Personal barriers to screening include the lack of awareness, and belief that cervical cancer is not preventable. Opportunistic screening, mass media campaigns and ANC education were suggested as ways of improving awareness and utilization of cervical cancer screening services.

Abstract
BACKGROUND Understanding the patterns of mammography use is essential to promote the participation in breast cancer screening. OBJECTIVES To describe the patterns of screening mammography use in Portugal. METHODS As part of the fourth National Health Survey (2005/2006), 3045 women were evaluated in face-to-face interviews. The previous use of mammography for screening was classified as never or ever, and the latter was further grouped according to the time elapsed since the latest mammography. Having undergone the latest mammography >2 years before was considered underuse. We assessed the determinants of never having been screened by mammography and, among those who had been tested, the determinants of mammography underuse, through age- and education-adjusted odds ratios (ORs), with 95% confidence intervals (95% CIs). RESULTS Among women aged 45-49 and 50-69 years, 86.3% and 88.0%, respectively, underwent a screening mammography before, and most of them were tested in the previous 2 years. The lowest risk of never having been screened was in Norte (OR = 0.41, 95% CI: 0.21-0.80) and the highest in Açores (OR = 4.04, 95% CI: 2.37-6.92), in comparison with Centro (the region with organized screening for a longer time). Participants with <4 years of formal education were more likely to have never been screened than the more educated (OR = 4.27, 95% CI: 1.67-10.89). Women with private health insurance (OR = 0.16, 95% CI: 0.04-0.65), as well as those who had undergone cervical cytology screening before (OR = 0.50, 95% CI: 0.30-0.85), had a lower risk of underuse. CONCLUSIONS This study provides useful information to improve the allocation of resources to breast cancer screening.

[PMID: 22355462 PMCID: PMC3280061 DOI: 10.3802/jgo.2012.23.1.16] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2011] [Revised: 10/21/2011] [Accepted: 11/01/2011] [Indexed: 01/16/2023] Open
Abstract
Objective The National Cancer Screening Program (NCSP) began in 1999. In this report, we evaluate the results of the NCSP for cervical cancer in 2009 and provide participation rates in an organized cervical cancer screening program in Korea. Methods Using data obtained from the National Cancer Screening Information System, cervical cancer screening participation rates were calculated. Recall rates, defined as the proportion of abnormal cases among women screened, were also estimated with 95% confidence intervals. Results The target population of cervical cancer screening in 2009 included 4,577,200 Korean women aged 30 and over, 1,349,668 of whom underwent the Papanicolaou smear test (29.5% participation rate). Compared with the participation rate of women covered by the National Health Insurance Program (31.3%), the participation rate of women covered by the Medical Aid Program was lower (18.4%). Participation rates also varied in different age groups (the highest of 39.3% in women aged 50 to 59 and the lowest of 14.4% in those aged 70 and older), and different areas (the highest of 34.1% in Busan and the lowest of 21.5% in Chungnam). The overall recall rate for cervical cancer screening was 0.41% (95% confidence interval, 0.40 to 0.42). Conclusion According to our study, efforts to facilitate participation and reduce disparities in cervical cancer screening among Korean women are needed.

Abstract
OBJECTIVE To explore awareness of and participation in cervical screening services in women from Poland, Slovakia and Romania living in London, UK. METHODS Three qualitative studies were carried out in London in 2008-2009: an interview study of professionals working with Central and Eastern European migrants (n=11); a focus group study including three Polish, one Slovak and one Romanian focus group; and an interview study of Polish (n=11), Slovak (n=7) and Romanian (n=2) women. RESULTS Awareness of the cervical screening programme was good, but understanding of the purpose of screening was sometimes limited. Some women were fully engaged with the UK screening programme; others used screening both in the UK and their countries of origin; and a third group only had screening in their home countries. Women welcomed the fact that screening is free and that reminders are sent, but some were concerned about the screening interval and the age of the first invitation. CONCLUSIONS Migrant women from Poland, Slovakia and Romania living in London vary in their level of participation in the National Health Service Cervical Screening Programme. More needs to be done to address concerns regarding screening services, and to ensure that language is not a barrier to participation.
