Role of caregivers being trained in assisting in end of life care - Latin American perspective.

PURPOSE OF REVIEW: Palliative care in Latin America is evolving, but training for informal caregivers remains underexplored. This review summarizes recent interventions to educate or train caregivers in end-of-life care. RECENT FINDINGS: The literature search identified three interventions published by 2023, two with reception evaluations, all with small sample sizes and no control groups. Needs of caregivers have been more frequently described and include training on aspects of the disease, nursing skills, how to handle patients´ and own emotions; help in navigating the complex healthcare systems in Latin America; help in conversations about the end of life and dying, still taboos in the region; help in finding additional caregivers or other types of support to make the caregiving role sustainable over time for the caregiver. Interventions mainly focused on emotional support and identifying additional caregivers without guilt; two included nursing skills training. SUMMARY: There are very few formal interventions described and evaluated to assist caregivers in end-of-life care in Latin America described in the literature. This illustrates the rather invisible but very important role of these important stakeholders in the care for patients. Multidimensional interventions should be developed and evaluated to support caregivers.

Population-based overall and net survival of childhood leukemia at 1-, 5-, and 10-years of follow-up in three regions of Colombia.

Background: Childhood leukemia (CL) is the most common type of childhood cancer worldwide and in Colombia. Thanks to therapeutic innovations and improved access, the survival of children and adolescents with leukemia has increased considerably worldwide, especially in high-income countries. In Colombia, a middle-income country, survival has also been observed to increase in big cities. However, the survival rate in intermediate cities is still unknown. Objective: This study aimed to assess short- and long-term survival rates of children with leukemia coming from three intermediate Colombian cities as well as to compare overall survival (OS) rates versus relative survival (RS) rates of this population of children. Methods: Data from population-based cancer registries in three Colombian cities (Bucaramanga metropolitan area, Manizales and Pasto) were analyzed. OS and RS of up to 10 years were estimated for children who were diagnosed with leukemia at ages 0-18 years between 1998 and 2018 and followed up for vital status. RS was calculated using the Pohar-Perme method. We performed a separate survival analysis by gender and by period of diagnosis (before and after 2010). Results: We included data from 507 children and adolescents diagnosed with leukemia. RS at 1, 5 and 10 years after diagnosis were similar between the populations for the respective timeframes (RS Bucaramanga 86.5%, 66.9% and 52.5%; Manizales 81.1%, 62.8% and 61.1%; Pasto 81.7% at 1 year, 66.2% at 5 years and 59.4% at 10 years). OS and RS were very similar for all estimates and periods. There were no clear differences in RS between genders across the three population-based cancer registries and there was an improvement in RS after 2010, particularly in Bucaramanga and Pasto. Conclusion: Our study reports similar 5-year survival rates for CL in these Colombian cities compared to rates documented in other Latin American countries and larger Colombian cities. These are far below what is reported in high-income settings. This highlights opportunities for improvement in the Colombian health system, where numerous barriers persist in terms of suspicion, diagnosis and continuity of treatment for CL.

Evidence-based decision-making in the treatment of speech, language, and communication disorders in Down syndrome; a scoping review.

This scoping review examined available scientific evidence according to the PRISMA-ScR guideline on the subject of treatment interventions by speech and language therapists of speech, language, and communication needs in people with Down syndrome. A literature search in PubMed, Embase, Cinahl, Cochrane, and Web of Science yielded 41 studies suitable for inclusion. All studies examined the effect of an intervention in speech, language or communicative behaviour, alone or in combination. Most studies were conducted among children, only four were conducted among adults. Twenty-three studies (49%) found statistically significant results. This review may encourage speech and language therapists to incorporate scientific evidence in making their treatment choices. Furthermore, it may inform health care professionals about potential speech and language treatments that can help people with Down syndrome in developing and maintaining their communicative skills. However, future research is needed because little research has been done in this area so far.

Developing research priorities for palliative care in Colombia: a priority setting partnership approach.

BACKGROUND: A recent Lancet commission called for more research on palliative care in low- and middle-income (LMIC) countries such as Colombia. A research priority setting approach has been recommended by The Global Forum for Health Research to address the huge gap in research output between LMIC and high-income countries, with influential health service bodies recommending the active involvement of non-research expert stakeholders in establishing research priorities to address service user needs. METHOD: Priority setting partnership (PSP) following the four stages of the James Lind Alliance methodology; establishing the partnership, identifying evidence uncertainties, refining questions and uncertainties, and prioritization. Data from MS forms were analysed using descriptive statistics. RESULTS: A total of 33 stakeholders attended an online PSP workshop and completed the Mentimeter exercise in Microsoft Teams. A total of 48 attended the subsequent in person prioritisation exercise in urban Bogota (n = 22) and rural Popayan (n = 25). The stakeholders were a diverse group of health professionals (physicians, medical students, nurses, dentists, physiotherapists, nutritionist, occupational and speech therapists), financial and administrative staff and patients with life-limiting illness and caregivers. Top research priorities included patient and caregiver needs, service provider education and training, and better integration of palliative care with cancer and non-cancer services. The key challenges included a lack of interest in palliative care research, along with funding, time and resource constraints. Key solutions included collaboration across disciplines and settings, highlighting benefits of palliative research to help secure adequate resources, and multicentre, mixed method research, with patient involvement from the research development stage. CONCLUSION: The findings of this PSP should be disseminated among palliative care associations worldwide to inform international multicentre studies, and among governmental and nongovernmental organisations that promote research in Colombia. A focus on patient and family caregiver palliative care needs in Colombia should be prioritised.

"You can be cured, but cancer never leaves you behind": an interdisciplinary approach into the embodied cancer experiences among adult Colombian childhood/adolescent cancer survivors.

PURPOSE: Childhood or adolescent cancer survivors (CACS) are an understudied population in Colombia and, in general, in Central and South America. Worldwide, studies typically focus on high-income settings while approaching CACS' experiences from a biomedical or psychological perspective. However, both perspectives miss an important aspect of survivorship after childhood or adolescent cancer: the affected individual's subjective experiences of having a disabled body. This qualitative study aimed to explore the embodied experiences of Colombian adults who survived cancer during their childhood or adolescence to better understand how CACS relate to their altered body and world. METHODS: By integrating phenomenological insights and conducting comprehensive life-story interviews, we explored the various ways in which survivors' cancer experiences affect their bodily sense of self-from the acute phase of the disease until well into adulthood. A total of ten life-stories interviews and one focus group were carried out with seven CACS. All participants were survivors of a different type of childhood/adolescent cancer. The results were analyzed thematically, focusing on the embodied aspects of participants' experiences. RESULTS: We developed three main themes regarding the embodied cancer experience among participating CACS: Firstly, participants' body changes because of the cancer and its treatment, which makes them aware of their body. Secondly, they adapt to this experience in different bodily ways. Finally, they carry bodily traces of their cancer experience in the present as well as into the future. CONCLUSIONS: The CACS participating in this study report that their experience with cancer has been embodied throughout their lives, changing their sense of their body and how they relate to it, and leaving traces into the present and their imagined future.

Age-period-cohort effects on incidence trends of childhood leukemia from four population-based cancer registries in Colombia.

BACKGROUND: Childhood leukemia (CL) is the most prevalent form of pediatric cancer on a global scale. However, there is a limited understanding of the dynamics of CL incidence in South America, with a specific knowledge gap in Colombia. This study aimed to identify trends in CL incidence and to analyze the effects of age, period, and birth cohort on the risk of leukemia incidence in this population. METHODS: Information on all newly diagnosed leukemia cases (in general and by subtype) among residents aged 0-18 years and living in the serving areas of population-based cancer registries of Cali (2008-2017), Bucaramanga (2000-2017), Manizales (2003-2017), and Pasto (1998-2018). Estimated annual percent changes (EAPC) in incidence over time and potential changes in the slope of these EAPCs were calculated using joinpoint regression models. The effects of age, period, and cohort in CL incidence trends were evaluated using age-period-cohort models addressing the identifiability issue through the application of double differences. RESULTS: A total of 966 childhood leukemia cases were identified. The average standardized incidence rate (ASIR) of leukemia was calculated and expressed per 100,000 person-years - observing ASIR of 4.46 in Cali, 7.27 in Bucaramanga, 3.89 in Manizales and 4.06 in Pasto. Concerning CL trends there were no statistically significant changes in EAPC throughout the different periods, however, when analyzed by leukemia subtype, statistically significant changes were observed in the EAPC for both ALL and AML. Analysis of age-period-cohort models revealed that age-related factors significantly underpin the incidence trends of childhood leukemia in these four Colombian cities. CONCLUSIONS: This study offers valuable insights into the incidence trends of childhood leukemia in four major Colombian cities. The analysis revealed stable overall CL incidence rates across varying periods, predominantly influenced by age-related factors and the absence of cohort and period effects. This information is useful for surveillance and planning purposes for CL diagnosis and treatment in Colombia.

Validation of the Spanish translation Sheffield Profile for Assessment and Referral for Care (SPARC-Sp) at the Hospital Universitario San Jose of Popayan, Colombia.

OBJECTIVES: We determined the validity and reliability of the Spanish translation Sheffield Profile for Assessment and Referral for Care (SPARC-Sp) questionnaire to identify the palliative care (PC) needs of patients with chronic noncommunicable diseases (NCDs) in Colombia. METHODS: We developed a cross-sectional observational study of scale assessment in adults with the aim of determining the validity and reliability of the SPARC-Sp questionnaire to identify the PC needs of patients with NCDs receiving outpatient or inpatient care at the Hospital Universitario San Jose of Popayan - ESE, Colombia, from 2021 to 2022. RESULTS: We applied a questionnaire consisting of demographic, clinical data, and SPARC-Sp to 507 participants. The constructed model explained 75% of the variance with an adequate fit according to the root mean square residual (0.03), the comparative fit index (0.98), and acceptable reliability (McDonald's total omega 0.4-0.9). Opportunities for improvement are the reformulation and inclusion of particular words to improve the representativeness and clarity of the domains of communication and information, religious, and spiritual issues. SIGNIFICANCE OF RESULTS: This research represents the first validation of SPARC in Spanish. SPARC-Sp is an instrument that allows initiating a conversation of the patient's main needs through a systematic assessment of the patients' main needs. Its psychometric validation demonstrated good fit and acceptable reliability.

Burden of non-serious infections during biological use for rheumatoid arthritis.

INTRODUCTION: Biologicals have become a cornerstone in rheumatoid arthritis (RA) treatment. The increased risk of serious infections associated with their use is well-established. Non-serious infections, however, occur more frequently and are associated with a high socioeconomic burden and impact on quality of life but have not received the same attention in the literature to date. The aim of this study was to gain insight into the various non-serious infections reported in RA patients using biologicals and their experienced burden. MATERIALS AND METHODS: The Dutch Biologic Monitor was a prospective observational study that included adults with rheumatoid arthritis and biological use who answered bimonthly questionnaires on the adverse drug reactions (ADRs) they experienced from their biological and reported the associated impact score (ranging from 1, no impact, to 5, very high impact). ADRs were assigned a MedDRA code by pharmacovigilance experts and labeled as definite, probable, possible or no infection by infectious disease professionals. Descriptive statistics were performed using medians and interquartile ranges. RESULTS: A total of 586 patients were included in the final analysis. Eighty-five patients (14.5%) reported a total of 421 ADRs labeled as probable or definite infections by the experts. Patient-assigned burden was ADR-specific. Upper respiratory tract infections were most frequently reported and had a high rate of recurrence or persistence, with a median impact score of 3.0 (IQR 2.0-3.0) which remained stable over time. DISCUSSION: Non-serious infections significantly outnumbered serious infections in this real-life cohort of RA patients using biologicals (77.1 non-serious infections and 1.3 serious infections per 100 patient years, respectively). Infections in the upper respiratory tract were rated as having an average burden, which remained constant over a long period of time. Awareness of the impact of recurrent and chronic non-serious infections may enable healthcare professionals to timely treat and maybe even prevent them, which would lessen the associated personal and socioeconomic burden.

Translation and linguistic validation of the Sheffield Profile for Assessment and Referral for Care (SPARC) to Colombian Spanish.

OBJECTIVES: We aimed to translate and linguistically and cross-culturally validate Sheffield Profile for Assessment and Referral for Care (SPARC) in Spanish for Colombia (SPARC-Sp). METHODS: The linguistic validation of SPARC followed a standard methodology. We conducted focus groups to assess the comprehensibility and feasibility. The acceptability was assessed using a survey study with potential users. RESULTS: The comprehensibility assessment showed that additional adjustments to those made during the translation-back-translation process were required to apply SPARC-Sp in rural and low-schooled populations. It also identified the need for alternative administration mechanisms for illiterate people. The acceptability survey showed that potential users found SPARC-Sp as not only acceptable but also highly desirable. However, they desired to expand the number of items in all domains. SIGNIFICANCE OF RESULTS: Beyond the semantic and conceptual validity attained through the back-translation process, actual cultural validity could be acquired thanks to the comprehensibility tests. Although extending the instrument is something potential users would like to do, it would make it less feasible to utilize the SPARC-Sp in clinical settings. Nonetheless, the instrument might benefit from the inclusion of a domain that evaluates challenges encountered when accessing the health-care system. For communities lacking literacy, alternate administration methods must also be considered.

The Human Phenotype Ontology in 2024: phenotypes around the world.

The Human Phenotype Ontology (HPO) is a widely used resource that comprehensively organizes and defines the phenotypic features of human disease, enabling computational inference and supporting genomic and phenotypic analyses through semantic similarity and machine learning algorithms. The HPO has widespread applications in clinical diagnostics and translational research, including genomic diagnostics, gene-disease discovery, and cohort analytics. In recent years, groups around the world have developed translations of the HPO from English to other languages, and the HPO browser has been internationalized, allowing users to view HPO term labels and in many cases synonyms and definitions in ten languages in addition to English. Since our last report, a total of 2239 new HPO terms and 49235 new HPO annotations were developed, many in collaboration with external groups in the fields of psychiatry, arthrogryposis, immunology and cardiology. The Medical Action Ontology (MAxO) is a new effort to model treatments and other measures taken for clinical management. Finally, the HPO consortium is contributing to efforts to integrate the HPO and the GA4GH Phenopacket Schema into electronic health records (EHRs) with the goal of more standardized and computable integration of rare disease data in EHRs.

Descriptive Epidemiology of Melanoma Diagnosed between 2010 and 2014 in a Colombian Cancer Registry and a Call for Improving Available Data on Melanoma in Latin America.

We aimed to improve the available information on morphology and stage for cutaneous melanoma in the population-based cancer registry of the Bucaramanga Metropolitan Area in Colombia. The incidence and survival rates and the distribution of melanoma patients by age, gender, anatomical subsite, and histological subtype were calculated. All 113 melanoma patients (median age 61) were followed up (median time 7.4 years). This exercise (filling in missing information in the registry by manual search of patient clinical record and other available information) yielded more identified invasive melanomas and cases with complete information on anatomical localization and stage. Age-standardized incidence and mortality rates were 1.86 and 1.08, being slightly higher for males. Most melanomas were localized on the lower limbs, followed by the trunk. For 35% of all melanomas, the morphological subtype remained unknown. Most of the remaining melanomas were nodular and acral lentiginous melanomas. Overall global and relative 5-year survival was 61.6% and 71.3%, respectively, with poorer survival for males than females. Melanomas on the head and neck and unspecified anatomical sites had the worst survival. Patients without stage information in their medical files had excellent survival, unlike patients for whom medical files were no longer available. This study shows the possibility of improving data availability and the importance of good quality population-based data.

Co-Designing a Strategy for Implementing the SPARC Holistic Needs Assessment Tool in the Colombian Clinical Context.

In Colombia, timely access to palliative care (PC) is hampered by difficulties in identifying and referring to necessary services. The SPARC (Sheffield Profile for Assessment and Referral for Care) instrument provides a holistic needs assessment to improve referrals for different forms of care. SPARC was recently validated in Colombian Spanish (SPARC-Sp) but has not yet been implemented in clinical practice. We undertook workshops that aimed to co-design an implementation strategy to inform a future trial testing SPARC-Sp in the Colombian healthcare system. Workshop attendees included patients, informal caregivers, healthcare professionals, volunteers, administrative staff and decision makers. Discussions within the workshops refined implementation and dissemination strategies for SPARC-Sp in practical scenarios. Results include the need for education, clarification and demystification of PC and the lack of time and skills of professionals to identify patients' needs. Attendees recognized SPARC-Sp as a valuable tool for highlighting patients' concerns, whose adaptations are needed in Colombia to address the low literacy of the population and specificities of the healthcare system. We proposed local adaptations to SPARC-Sp and produced five educational videos aimed at health professionals, patients and caregivers to strengthen understanding of holistic needs in PC while building a strategy for SPARC-Sp implementation in the Colombian context.

Barriers and facilitators to palliative care for patients with non-curable cancer in Colombia: perspectives of allied health and social care professionals.

BACKGROUND: Palliative care aims to improve the quality of life of people with life-limiting illness and their families by addressing physical, psychological, social and spiritual suffering. Allied Health and Social Care Professionals (AHSCP) are key to delivering comprehensive, high quality palliative care. In recent years, Colombia has developed changes in the legal, and regulatory framework for access to palliative care but barriers and facilitators to palliative care for patients with non-curable cancer have not been explored from the perspective of AHSCP. METHOD: This study aims to address this knowledge gap in two cities in Colombia: one in a medium-sized city in a rural area (Popayan) and one in a highly urbanized area (Bogota). Two focus groups with AHSCP were conducted using the World Cafe method, and a subsequent thematic analysis was performed to establish the main barriers and facilitators. RESULTS: A wide range of 18 AHSCPs attended the two World Cafe groups in Popayan and Bogota. As a result of this iterative process, we established five thematic areas: (i) Humanizing care, (ii) Normalizing palliative care: referral at the time of diagnosis, (iii) Misunderstandings related to palliative care, (iv) Barriers within the health system, and (v) Geographic barriers. CONCLUSION: This study provided the perspectives of AHSCPs in Colombia in relation to barriers and facilitators in the framework of comprehensive palliative care attention. Participants identified misconceptions about palliative care, which are explained by the lack of inclusion of this area in the educational programs of health professionals and AHSCPs, along with the limited supply and access to palliative care, especially in rural areas.

End of Life in Patients With Advanced Non-curable Cancer: Patient Considerations Around the Moment of Death.

There is limited knowledge regarding Colombian patients with advanced cancer preferences regarding their final moments, place of death, and post-death wishes. To better understand these preferences, we conducted 23 in-depth interviews with patients between the ages of 28 and 78 receiving treatment at two academic hospitals and the National Cancer Institute. While many participants desired a peaceful death, few were comfortable discussing the topic of death directly. Some younger participants expressed an interest in euthanasia but had not received any guidance or support. While several participants preferred a home death, some expressed a desire to die in a hospital due to better symptom control. Additionally, when discussing post-death wishes, some participants expressed frustration about being unable to have these conversations with their loved ones and their preferences for funeral arrangements. Socioeconomic and geographical factors significantly impacted the wishes and preferences expressed, with many individuals hesitant to initiate difficult conversations.

Infections in Biological and Targeted Synthetic Drug Use in Rheumatoid Arthritis: Where do We Stand? A Scoping Review and Meta-analysis.

INTRODUCTION: The advent of biological and targeted synthetic therapies has revolutionized rheumatoid arthritis (RA) treatment. However, this has come at the price of an increased risk of infections. The aim of this study was to present an integrated overview of both serious and non-serious infections, and to identify potential predictors of infection risk in RA patients using biological or targeted synthetic drugs. METHODS: We systematically reviewed available literature from PubMed and Cochrane and performed multivariate meta-analysis with meta-regression on the reported infections. Randomized controlled trials and prospective and retrospective observational studies including patient registry studies were analyzed, combined as well as separately. We excluded studies focusing on viral infections only. RESULTS: Infections were not reported in a standardized manner. Meta-analysis showed significant heterogeneity that persisted after forming subgroups by study design and follow-up duration. Overall, the pooled proportions of patients experiencing an infection during a study were 0.30 (95% CI, 0.28-0.33) and 0.03 (95% CI, 0.028-0.035) for any kind of infections or serious infections only, respectively. We found no potential predictors that were consistent across all study subgroups. CONCLUSIONS: The high heterogeneity and the inconsistency of potential predictors between studies show that we do not yet have a complete picture of infection risk in RA patients using biological or targeted synthetic drugs. Besides, we found non-serious infections outnumbered serious infections by a factor 10:1, but only a few studies have focused on their occurrence. Future studies should apply a uniform method of infectious adverse event reporting and also focus on non-serious infections and their impact on treatment decisions and quality of life.

The impact of health insurance affiliation and socioeconomic status on cervical cancer survival in Bucaramanga, Colombia.

Cervical cancer is still an important cause of death in countries like Colombia. We aimed to determine whether socioeconomic status of residential address (SES) and type of health insurance affiliation (HIA) might be associated with cervical cancer survival among women in Bucaramanga, Colombia. All patients residing in the Bucaramanga Metropolitan Area diagnosed with invasive cervical cancer (ICD-0-3 codes C53.X) between 2008 and 2016 (n = 725) were identified through the population-based cancer registry, with 700 women having follow-up data for >5 years (date of study closure: Dec 31, 2021), yielding an overall 5-year survival estimate (95 % CI) of 56.4 % (52.7 - 60.0 %). KM estimates of 5-year overall survival were obtained to assess differences in cervical cancer survival by SES and HIA. Multivariable Cox-proportional hazards modeling was also conducted, including interaction effects between SES and HIA. Five-year overall survival was lower when comparing low vs. high SES (41.9 % vs 57.9 %, p < 0.0001) and subsidized vs. contributive HIA (45.1 % vs 63.0 %, p < 0.0001). Multivariable Cox modeling showed increased hazard ratios (HR) of death for low vs. high SES (HR = 1.78; 95 % CI = 1.18-2.70) and subsidized vs. contributive HIA (HR = 1.44; 95 % CI = 1.13-1.83). The greatest disparity in HR was among women of low SES affiliated to subsidized HIA (vs. contributive HIA and high SES) (HR=2.53; 95 % CI = 1.62-3.97). Despite Colombia's universal healthcare system, important disparities in cervical cancer survival by health insurance affiliation and socioeconomic status remain.

Factors associated with suffering from dying in patients with cancer: a cross-sectional analytical study among bereaved caregivers.

BACKGROUND: In Colombia, cancer incidence is increasing, as is the demand for end-of-life care. Understanding how patients who die from cancer experience this phase will allow the identification of factors associated with greater suffering and actions to improve end-of-life care. We aimed to explore associations between the level of suffering of patients who died from cancer and were cared for in three Colombian hospitals with patient, tumor, treatment, and care characteristics and provided information. METHODS: Data on the last week of life and level of suffering were collected through proxies: Bereaved caregivers of patients who died from cancer in three participating Colombian hospitals. Bereaved caregivers participated in a phone interview and answered a series of questions regarding the last week of the patient's life. An ordinal logistic regression model explored the relationship between the level of suffering reported by bereaved caregivers with the patient's demographic and clinical characteristics, the bereaved caregivers, and the care received. Multivariate analyses were adjusted for place of death, treatments to prolong of life, prolongation of life during the dying process, suffering due to prolongation of life, type of cancer, age, if patient had partner, rural/urban residence of patient, importance of religion for the caregiver, caregivers´ relationship with the patient, and co-living with the patient. RESULTS: A total of 174 interviews were included. Median age of the deceased patients was 64 years (IQR 52-72 years), and 93 patients were women (53.4%). Most caregivers had rated the level of suffering of their relative as "moderately to extremely" (n = 139, 80%). In multivariate analyses, factors associated with a higher level of suffering were: unclear information about the treatment and the process before death Odds Ratio (OR) 2.26 (90% CI 1.21-4.19), outpatient palliative care versus home care OR 3.05 (90% CI 1.05-8.88), procedures inconsistent with the patient's wishes OR 2.92 (90% CI 1.28-6.70), and a younger age (18-44 years) at death versus the oldest age group (75-93 years) OR 3.80 (90% CI 1.33-10.84, p = 0.04). CONCLUSION: End-of-life care for cancer patients should be aligned as much as possible with patients´ wishes, needs, and capacities. A better dialogue between doctors, family members, and patients is necessary to achieve this.

Socioeconomic inequalities in cancer mortality between and within countries in Europe: a population-based study.

Background: Reducing socioeconomic inequalities in cancer is a priority for the public health agenda. A systematic assessment and benchmarking of socioeconomic inequalities in cancer across many countries and over time in Europe is not yet available. Methods: Census-linked, whole-of-population cancer-specific mortality data by socioeconomic position, as measured by education level, and sex were collected, harmonized, analysed, and compared across 18 countries during 1990-2015, in adults aged 40-79. We computed absolute and relative educational inequalities; temporal trends using estimated-annual-percentage-changes; the share of cancer mortality linked to educational inequalities. Findings: Everywhere in Europe, lower-educated individuals have higher mortality rates for nearly all cancer-types relative to their more highly-educated counterparts, particularly for tobacco/infection-related cancers [relative risk of lung cancer mortality for lower- versus higher-educated = 2.4 (95% confidence intervals: 2.1-2.8) among men; = 1.8 (95% confidence intervals: 1.5-2.1) among women]. However, the magnitude of inequalities varies greatly by country and over time, predominantly due to differences in cancer mortality among lower-educated groups, as for many cancer-types higher-educated have more similar (and lower) rates, irrespective of the country. Inequalities were generally greater in Baltic/Central/East-Europe and smaller in South-Europe, although among women large and rising inequalities were found in North-Europe (relative risk of all cancer mortality for lower- versus higher-educated ≥1.4 in Denmark, Norway, Sweden, Finland and the England/Wales). Among men, rate differences (per 100,000 person-years) in total-cancer mortality for lower-vs-higher-educated groups ranged from 110 (Sweden) to 559 (Czech Republic); among women from approximately null (Slovenia, Italy, Spain) to 176 (Denmark). Lung cancer was the largest contributor to inequalities in total-cancer mortality (between-country range: men, 29-61%; women, 10-56%). 32% of cancer deaths in men and 16% in women (but up to 46% and 24%, respectively in Baltic/Central/East-Europe) were associated with educational inequalities. Interpretation: Cancer mortality in Europe is largely driven by levels and trends of cancer mortality rates in lower-education groups. Even Nordic-countries, with a long-established tradition of equitable welfare and social justice policies, witness increases in cancer inequalities among women. These results call for a systematic measurement, monitoring and action upon the remarkable socioeconomic inequalities in cancer existing in Europe. Funding: This study was done as part of the LIFEPATH project, which has received financial support from the European Commission (Horizon 2020 grant number 633666), and the DEMETRIQ project, which received support from the European Commission (grant numbers FP7-CP-FP and 278511).

Modelling the Reduction in Cancer Incidence After Variations in the Prevalence of Tobacco Consumption in Colombia in the Period 2016-2050.

OBJECTIVE: To evaluate the potential impact of tobacco reduction on future cancer incidence in Colombia. INTRODUCTION: Colombia has implemented multiple actions that led to reducing smoking prevalence in recent years. However, the numbers of cancer cases and deaths associated with smoking exposure remain high highlighting the importance of maintaining efforts to reduce and keep smoking prevalence low. METHODS: We performed a theoretical modeling exercise, projecting expected changes in the incidence of four cancers between 2016 and 2050 under two simulated scenarios of smoking reduction. RESULTS: A cumulative decline of 10% in the prevalence of smoking, a percentage in line with current cigarette taxation policies, will decrease cancer incidence in 2050 by 3.2%, .5%, .2% and .2% of lung, liver, cervical and colorectal cancer incidence, respectively. Complete elimination of tobacco consumption will reduce these by 39.1%, 6.1%, 2.2% and 2.3% respectively, by 2050. CONCLUSION: These results highlight the importance of continuity and reinforcement of current tobacco control programs, including increasing taxation, to further reduce the prevalence of tobacco smoking and reduce cancer cases and deaths in the coming decades.
