RESUMO
Cardiovascular disease (CVD) and cancer are leading causes of mortality and morbidity worldwide and are the major focus of the World Health Organization's joint prevention programs. While, diverse diseases, CVD and cancer, have many similarities. These include common lifestyle-related risk factors and shared environmental, metabolic, cellular, inflammatory, and genetic pathways. In this review, we will discuss the shared lifestyle-related and environmental risk factors central to both diseases and how the strategies commonly used to prevent atherosclerotic vascular disease can be applied to cancer prevention.

Patient-reported outcomes (PROs), such as symptoms, function, and other health-related quality-of-life aspects, are increasingly evaluated in cancer randomised controlled trials (RCTs) to provide information about treatment risks, benefits, and tolerability. However, expert opinion and critical review of the literature showed no consensus on optimal methods of PRO analysis in cancer RCTs, hindering interpretation of results. The Setting International Standards in Analyzing Patient-Reported Outcomes and Quality of Life Endpoints Data Consortium was formed to establish PRO analysis recommendations. Four issues were prioritised: developing a taxonomy of research objectives that can be matched with appropriate statistical methods, identifying appropriate statistical methods for PRO analysis, standardising statistical terminology related to missing data, and determining appropriate ways to manage missing data. This Policy Review presents recommendations for PRO analysis developed through critical literature reviews and a structured collaborative process with diverse international stakeholders, which provides a foundation for endorsement; ongoing developments of these recommendations are also discussed.

AIMS: To explore available health behaviour change interventions in improving key health behaviours in colorectal cancer survivors and patient perspectives about these interventions. DESIGN: A systematic mixed studies review was conducted. DATA SOURCES: Databases searched included Ovid Medline, Ovid Embase, EBSCO PsychoInfo and EBSCO CINAHL. A grey literature search was also completed using Google Scholar and the TRIP database. Identified studies were published between 2003 - 2018. REVIEW METHODS: A parallel-results convergent synthesis design using narrative syntheses was used. Data analysis was conducted following a process of constant comparison. Quality appraisal was conducted using recognized tools appropriate to different study designs. RESULTS: Sixteen unique studies were identified from an initial search of 354 records. There was a pattern of successful physical activity and dietary change associated with behaviour change interventions of varying intensity, modality and length, but sparse description of intervention content was common. Participants preferred clear explanations of health behaviour importance and for interventions to be administered in sessions either with, or led by, other patients. CONCLUSION: The available evidence tentatively suggests that behaviour change interventions can improve the health behaviours of colorectal cancer survivors. However, more research focused on identifying key intervention elements is needed. Patients indicated clear preferences for specific intervention content and delivery, but further research is needed to allow for the appropriate incorporation of patient preferences into the design of such interventions. IMPACT: This review highlights the potential for interventions to improve health behaviours evidenced to influence short and long-term health outcomes in colorectal cancer survivors. However, the examination of the impact of these interventions and patient perspectives indicated a paucity of research. This is an important finding in demonstrating additional research is necessary to improve the support available to a growing group of patients with complex health needs.
RESUMO
A previous review published in 2008 highlighted the prognostic significance of baseline patient-reported outcomes (PROs) as independent predictors of the overall survival of patients with cancer in clinical studies. In response to the methodological limitations of studies included in the previous review, recommendations were subsequently published in the same year to promote a higher level of methodological rigour in studies of prognostic factors. Our systematic review aimed to provide an update on progress with the implementation of these recommendations and to assess whether the methodological quality of prognostic factor analyses has changed over time. Of the 44 studies published between 2006 and 2018 that were included in our review, more standardisation and rigour of the methods used for prognostic factor analysis was found compared with the previous review. 41 (93%) of the trials reported at least one PRO domain as independently prognostic. The most common significant prognostic factors reported were physical functioning (17 [39%] studies) and global health or quality of life (15 [34%] studies). These findings highlight the value of PROs as prognostic or stratification factors in research across most types of cancer.

BACKGROUND: Physical activity (PA) is a safe and effective strategy to help mitigate health challenges associated with breast cancer (BC) survivorship. However, the majority of BC survivors are not meeting the minimum recommended PA (≥150 min of moderate to vigorous intensity). Project MOVE was developed as a model for increasing PA that combined a) Microgrants: funds ($2000) awarded to applicant groups to develop and implement a PA initiative and b) Financial incentives: a reward ($500) for increasing group PA. The purpose of this paper was to provide an exploratory analysis of effectiveness of Project MOVE on PA behavior, PA motivation, and quality of life (QoL) in female BC survivors. The differential outcomes between women meeting and not meeting PA guidelines were also investigated. METHODS: This pre-post test, preliminary trial included groups of adult (18+ years) self-identified female BC survivors, who were post-surgery and primary systemic chemo- and radiation therapy, and living in British Columbia, Canada. PA was assessed by accelerometry. PA motivation and QoL were assessed by self-report. Data were collected at baseline, 6-months, and 12-month time points. Repeated measures mixed ANOVAs were used to test changes in the main outcomes. RESULTS: A total of 10 groups were awarded microgrants between May 2015 and January 2016. Groups comprised of 8 to 12 women with a total of 87 participants. A statistically significant increase was found between time points on weekly moderate to vigorous PA (p = .012). This was mediated by a significant interaction between those meeting PA guidelines and those not meeting guidelines at baseline by time points (p = .004), with those not meeting guidelines at baseline showing the greatest increase in MVPA. A statistically significant difference across time points was found for intrinsic motivation (p = .02), physical functioning (p < .001), physical health limitations (p = .001), emotional health limitations (p = .023), social functioning (p = .001) and general health (p = .004). CONCLUSION: These results provide promising support for a unique approach to increasing PA among BC survivors by empowering women and optimizing PA experiences through the use of microgrants and financial incentives. TRIAL REGISTRATION: ClinicalTrials.gov NCT03548636 , Retrospectively registered June 7, 2018.

Appropriate intake of micronutrient, such as electrolyte minerals is critical for the well-being of the cardiovascular health system. However, there are some debates regarding the impacts of dietary and/or supplemental intake of these minerals, on the risk of cardiovascular events and associated risk factors. High sodium intake is adversely associated with the risk of hypertension. Although many reports refered to the positive association of Na intake and cardiovascular events and all-cause mortality, however, other studies indicated that low Na intake is related to higher risk of all-cause mortality and HF-related events. By contrast, dietary potassium, magnesium and calcium have an inverse correlation with cardiovascular events and risk factors, especially with blood pressure. There are some controversies about cardiovascular effects and all-cause mortality of high Ca intake, including no effect, preventive or adverse effect with or without vitamin D. Calcium supplementation might be beneficial for prevention of cardiovascular events and all-cause mortality only in individuals with low intake. Moreover, calcium intake showed a J- or U-shaped association with the risk of cardiovascular diseases. Due to the controversies of the effect of electrolyte minerals especially sodium and calcium intake on cardiovascular events, large scale, well-designed long-term randomized clinical trials are required to evaluate the effect of minerals intake on cardiovascular events and all-cause mortality. In this review, we discuss the role of dietary and or supplemental sodium, potassium, magnesium, calcium, in cardiovascular health, as well as their clinical applications, benefits, and risks for the primary prevention of cardiovascular disease, in general population.

Minerals play a major role in regulating cardiovascular function. Imbalances in electrolyte minerals are frequent and potentially hazardous occurrences that may lead to the development of cardiovascular diseases (CVDs). Transition metals, such as iron, zinc, copper and selenium, play a major role in cell metabolism. However, there is controversy over the effects of dietary and supplemental intake of these metals on cardiovascular risk factors and events. Since their pro-oxidant or antioxidant functions can have different effects on cardiovascular health. While deficiency of these trace elements can cause cardiovascular dysfunction, several studies have also shown a positive association between metal serum levels and cardiovascular risk factors and events. Thus, a J- or U-shaped relationship between the transition minerals and cardiovascular events has been proposed. Given the existing controversies, large, well-designed, long-term, randomized clinical trials are required to better examine the effects of trace mineral intake on cardiovascular events and all-cause mortality in the general population. In this review, we discuss the role of dietary and/or supplemental iron, copper, zinc, and selenium on cardiovascular health. We will also clarify their clinical applications, benefits, and harms in CVDs prevention.

Although models of cancer survivorship care are rapidly evolving, there is increasing evidence of health disparities among cancer survivors. In the current context, Canada's survivorship care systems privilege some and not others to receive high-quality care and optimize their health outcomes. The aim of this study was to improve survivorship care systems by helping clinicians and decision makers to a better understanding of how various psychosocial/political factors, survivors' health experiences and health management strategies might shape the development of and access to high-quality survivorship care for Canadians with cancer. Using a nursing epistemological approach informed by critical and intersectional perspectives, we conducted a three-phased Interpretive Description study. We engaged in critical textual analysis of documentary sources, a secondary analysis of interview transcripts from an existing database, and qualitative interviews with 34 survivors and 12 system stakeholders. On the basis of these data, we identified individual, group, and system factors that contributed to gaps between survivors' expected and actual survivorship care experiences. By understanding what shapes survivorship care systems and resources, we help illuminate and unravel the complex nature of the issue, supporting clinicians and decision makers to find multi-layered approaches for equitably high-quality survivorship care.
RESUMO
Although patient-reported outcomes (PROs), such as health-related quality of life, are important endpoints in randomised controlled trials (RCTs), there is little consensus about the analysis, interpretation, and reporting of these data. We did a systematic review to assess the variability, quality, and standards of PRO data analyses in advanced breast cancer RCTs. We searched PubMed for English language articles published in peer-reviewed journals between Jan 1, 2001, and Oct 30, 2017. Eligible articles were those that reported PRO results from RCTs of adult patients with advanced breast cancer receiving anti-cancer treatments with reported sample sizes of at least 50 patients-66 RCTs met the selection criteria. Only eight (12%) RCTs reported a specific PRO research hypothesis. Heterogeneity in the statistical methods used to assess PRO data was observed, with a mixture of longitudinal and cross-sectional techniques. Not all articles addressed the problem of multiple testing. Fewer than half of RCTs (28 [42%]) reported the clinical significance of their findings. 48 (73%) did not report how missing data were handled. Our systematic review shows a need to improve standards in the analysis, interpretation, and reporting of PRO data in cancer RCTs. Lack of standardisation makes it difficult to draw robust conclusions and compare findings across trials. The Setting International Standards in the Analyzing Patient-Reported Outcomes and Quality of Life Data Consortium was set up to address this need and develop recommendations on the analysis of PRO data in RCTs.

BACKGROUND: The aims of this study were to externally validate an established association between baseline health-related quality of life (HRQOL) scores and survival and to assess the added prognostic value of HRQOL with respect to demographic and clinical indicators. METHODS: Pooled data were analyzed from 17 randomized controlled trials opened by the Canadian Cancer Trials Group between 1991 and 2004; they included survival and baseline HRQOL data from 3606 patients with 8 different cancer sites. The models included sex, age (≤60 vs >60 years), World Health Organization performance status (0 or 1 vs 2-4), distant metastases (no vs yes), and 15 European Organization for Research and Treatment of Cancer (EORTC) Core Quality-of-Life Questionnaire (QLQ-C30) scales. Analyses were conducted with multivariate Cox proportional hazards models and were stratified by cancer site. Harrell's discrimination C-index was used to calculate the predictive accuracy of the model when HRQOL parameters were added to clinical and demographic variables. The added value of adding HRQOL scales to clinical and demographic variables was illustrated with Kaplan-Meier curves. RESULTS: In the stratified, multivariate model, HRQOL parameters-global health status (hazard ratio [HR], 0.97; 95% confidence interval [CI], 0.95-1.00; P < . 0001), dyspnea (HR, 1.04; 95% CI, 1.02-1.06; P < . 0002), and appetite loss (HR, 1.06; 95% CI, 1.04-1.08; P < . 0001)-were independent prognostic factors in addition to the demographic and clinical variables (all P values < .05). Adding these HRQOL variables to the clinical variables resulted in an added relative prognostic value for survival of 5%. CONCLUSIONS: These results confirm previous findings showing that baseline HRQOL scores on the EORTC QLQ-C30 provide prognostic information in addition to information from clinical measures. However, the impact of specific domains may differ across studies. Cancer 2018. © 2018 American Cancer Society.

BACKGROUND: Adjuvant endocrine therapy (AET) significantly reduces recurrence and mortality in women with breast cancer (BrCa). Despite the efficacy of AET in improving BrCa outcomes, up to 50% of women do not adhere to prescribed AET regimens. While numerous demographic and clinical predictors influence adherence and persistence, few studies have identified the patient-reported factors that influence AET adherence and persistence. PURPOSE: The aim was to examine the patient-reported personal, social, and structural factors influencing BrCa survivors' adherence and persistence with AET. METHODS: An integrative review was undertaken wherein PubMed, Medline, CINAHL, Embase, and PsycINFO databases were searched using keyword descriptors and database subject headings. Inclusion criteria included quantitative or qualitative peer-reviewed studies written in English that assessed AET adherence and/or persistence through objective measurement or self-report and included patient-reported factors found to influence adherence and/or persistence. The data extracted from eligible studies were entered into a matrix, and systematically compared and iteratively analyzed using relational autonomy as an organizing theoretical framework. RESULTS: A total of 43 manuscripts (9 qualitative and 34 quantitative) were reviewed. Several personal, social, and structural factors were identified that influenced AET adherence and persistence, including side effects, necessity beliefs, self-efficacy, the patient-healthcare provider relationship, social support, and continuity of follow-up care. CONCLUSIONS: An increasing number of studies have focused on identifying the patient-reported factors that influence AET adherence and persistence. This review highlights important personal, social, and structural factors that act as facilitators and barriers in adhering to and persisting with long-term AET. Acknowledging and addressing these factors is key to providing women with the care needed to improve suboptimal adherence and persistence.

PURPOSE: The association between high mammographic density (MD) and elevated breast cancer risk is well established. However, the role of absolute non-dense area remains unclear. We estimated the effect of the mammographic non-dense area and other density parameters on the risk of breast cancer. METHODS: This study utilizes data from a population-based case-control study conducted in Greater Vancouver, British Columbia, with 477 female postmenopausal breast cancer cases and 588 female postmenopausal controls. MD measures were determined from digitized screening mammograms using computer-assisted software (Cumulus). Marginal odds ratios were estimated by inverse-probability weighting using a causal diagram for confounder selection. Akaike information criteria and receiver operating characteristic curves were used to assess the goodness of fit and predictive power of unconditional logistic models containing MD parameters. RESULTS: The risk of breast cancer is 60% lower for the highest quartile compared to the lowest quartile of mammographic non-dense area (marginal OR 0.40, 95% CI 0.26-0.61, p-trend < 0.001). The cancer risk almost doubles for the highest quartile compared to the lowest quartile of dense area (marginal OR 1.81, 95% CI 1.19-2.43, p-trend < 0.001). For the highest quartile of percent density, breast cancer risk was more than three times higher than for the lowest quartile (marginal OR 3.15, 95% CI 1.90-4.40, p-trend < 0.001). No difference was seen in predictive accuracy between models using percent density alone, dense area alone, or non-dense area plus dense area. CONCLUSIONS: In this study, non-dense area is an independent risk factor after adjustment for dense area and other covariates, inversely related with the risk of breast cancer. However, non-dense area does not improve prediction over that offered by percent density or dense area alone.

BACKGROUND: Adjuvant endocrine therapy (AET) significantly decreases the risk of breast cancer recurrence and mortality. Notwithstanding the demonstrated efficacy of AET, 31-73% of breast cancer survivors do not persist with AET. The purpose of this study was to explore breast cancer survivors' experiences and perspectives of persisting with AET and to identify the psychosocial and healthcare system factors that influence AET persistence. METHODS: Informed by interpretive descriptive methodology and relational autonomy theory, individual interviews were conducted with 22 women diagnosed with early-stage breast cancer who had been prescribed AET. These participants also completed a demographic form and a survey that assessed their perceived risk of recurrence. Interviews were analysed using inductive thematic and constant comparative analysis to iteratively compare data and develop conceptualizations of the relationships among data. Descriptive statistics were used to summarize the quantitative data. RESULTS: The personal, social, and structural factors found to influence AET persistence included AET side effects, perception of breast cancer recurrence risk, medication and necessity beliefs, social support, the patient-provider relationship, and the continuity and frequency of follow-up care. For most women, over time, the decision-making process around AET persistence became a balancing act between quality of life and quantity of life. The interplay between the personal, social, and structural factors was complex and the weight women placed on some factors over others influenced their AET persistence or non-persistence. CONCLUSION: Expanding our understanding of the factors affecting breast cancer survivors' AET persistence from their perspective is the first step in developing efficacious, patient-centered interventions aimed at improving AET persistence. In order to improve AET persistence, enhanced symptom management is required, as well as the development of supportive care strategies that acknowledge the values and beliefs held by breast cancer survivors while reinforcing the benefits of AET, and addressing women's reasons for non-persistence. Improved continuity of health care and patient-healthcare provider communication across oncology and primary care settings is also required. The development and evaluation of supportive care strategies that address the challenges associated with AET experienced by breast cancer survivors hold the potential to increase both women's quality and quantity of life.

OBJECTIVE: Despite the physical and psychological health benefits associated with physical activity (PA) for breast cancer (BC) survivors, up to 70% of female BC survivors are not meeting minimum recommended PA guidelines. The objective of this study was to evaluate acceptability and satisfaction with Project MOVE, an innovative approach to increase PA among BC survivors through the combination of microgrants and financial incentives. METHODS: A mixed-methods design was used. Participants were BC survivors and support individuals with a mean age of 58.5 years. At 6-month follow-up, participants completed a program evaluation questionnaire (n = 72) and participated in focus groups (n = 52) to explore their experience with Project MOVE. RESULTS: Participants reported that they were satisfied with Project MOVE (86.6%) and that the program was appropriate for BC survivors (96.3%). Four main themes emerged from focus groups: (1) acceptability and satisfaction of Project MOVE, detailing the value of the model in developing tailored group-base PA programs; (2) the importance of Project MOVE leaders, highlighting the value of a leader that was organized and a good communicator; (3) breaking down barriers with Project MOVE, describing how the program helped to address common BC related barriers; and (4) motivation to MOVE, outlining how the microgrants enabled survivors to be active, while the financial incentive motivated them to increase and maintain their PA. CONCLUSION: The findings provide support for the acceptability of Project MOVE as a strategy for increasing PA among BC survivors.

BACKGROUND: The Global Burden of Disease Study represents a large and systematic effort to describe the burden of diseases and injuries over the past 3 decades. We aimed to summarize the Canadian data on burden of diseases and injuries. METHODS: We summarized data from the 2016 iteration of the Global Burden of Disease Study to provide current (2016) and historical estimates for all-cause and cause-specific diseases and injuries using mortality, years of life lost, years lived with disability and disability-adjusted life years in Canada. We also compared changes in life expectancy and health-adjusted life expectancy between Canada and 21 countries with a high sociodemographic index. RESULTS: In 2016, leading causes of all-age disability-adjusted life years were neoplasms, cardiovascular diseases, musculoskeletal diseases, and mental and substance use disorders, which together accounted for about 56% of disability-adjusted life years. Between 2006 and 2016, the rate of all-cause age-standardized years of life lost declined by 12%, while the rate of all-cause age-standardized years lived with disability remained relatively stable (+1%), and the rate of all-cause age-standardized disability-adjusted life year declined by 5%. In 2016, Canada aligned with countries that have a similar high sociodemographic index in terms of life expectancy (82 yr) and health-adjusted life expectancy (71 yr). INTERPRETATION: The patterns of mortality and morbidity in Canada reflect an aging population and improving patterns of population health. If current trends continue, Canada will continue to face challenges of increasing population morbidity and disability alongside decreasing premature mortality.

BACKGROUND: There is currently a lack of consensus on how health-related quality of life and other patient-reported outcome measures in cancer randomized clinical trials are analyzed and interpreted. This makes it difficult to compare results across randomized controlled trials (RCTs) synthesize scientific research, and use that evidence to inform product labeling, clinical guidelines, and health policy. The Setting International Standards in Analyzing Patient-Reported Outcomes and Quality of Life Endpoints Data for Cancer Clinical Trials (SISAQOL) Consortium aims to develop guidelines and recommendations to standardize analyses of patient-reported outcome data in cancer RCTs. METHODS AND RESULTS: Members from the SISAQOL Consortium met in January 2017 to discuss relevant issues. Data from systematic reviews of the current state of published research in patient-reported outcomes in cancer RCTs indicated a lack of clear reporting of research hypothesis and analytic strategies, and inconsistency in definitions of terms, including "missing data,""health-related quality of life," and "patient-reported outcome." Based on the meeting proceedings, the Consortium will focus on three key priorities in the coming year: developing a taxonomy of research objectives, identifying appropriate statistical methods to analyze patient-reported outcome data, and determining best practices to evaluate and deal with missing data. CONCLUSION: The quality of the Consortium guidelines and recommendations are informed and enhanced by the broad Consortium membership which includes regulators, patients, clinicians, and academics.

Measures of health-related quality of life (HRQOL) and other patient-reported outcomes generate important data in cancer randomised trials to assist in assessing the risks and benefits of cancer therapies and fostering patient-centred cancer care. However, the various ways these measures are analysed and interpreted make it difficult to compare results across trials, and hinders the application of research findings to inform publications, product labelling, clinical guidelines, and health policy. To address these problems, the Setting International Standards in Analyzing Patient-Reported Outcomes and Quality of Life Endpoints Data (SISAQOL) initiative has been established. This consortium, directed by the European Organisation for Research and Treatment of Cancer (EORTC), was convened to provide recommendations on how to standardise the analysis of HRQOL and other patient-reported outcomes data in cancer randomised trials. This Personal View discusses the reasons why this project was initiated, the rationale for the planned work, and the expected benefits to cancer research, patient and provider decision making, care delivery, and policy making.

BACKGROUND: Prior survivorship research has largely focused on issues faced by survivors of childhood tumors, breast cancers, or hematologic malignancies. Relatively little is known about the needs of other prevalent survivor groups. Our aim was to identify the specific concerns of colorectal cancer (CRC) survivors in the key domains of physical functioning, psychological wellbeing, and social relationships. METHODS: We conducted focus groups with stage II and III CRC survivors who had completed their primary active anti-cancer treatments. Patients were asked to describe how their diagnosis and treatment impacted their lives, to outline deficiencies in the care that they received, and to suggest ways of addressing any unmet needs. A content analysis was subsequently conducted to identify major themes. RESULTS: Thirty CRC survivors participated in six focus groups. Individuals reported some degree of dissatisfaction with the amount and type of diagnostic and treatment information they received at their initial clinic visit. Distress from toxicities, such as peripheral neuropathy, was also common among the survivors. Similarly, the majority faced challenges adjusting to their lives and daily activities, especially in caring for their colostomy. Having survived CRC, many survivors expressed an interest in advocacy and health promotion of CRC. CONCLUSIONS: CRC survivors face many barriers after their cancer treatment. Issues with colostomy are unique to this survivor group. Interventions to improve CRC survivorship care should also incorporate opportunities for patient advocacy.

Cancer mortality among indigenous peoples is increasing, but these populations commonly under use cancer-screening services. This systematic review explores knowledge, attitudes, and behaviours towards cancer screening among indigenous peoples worldwide. Searches of major bibliographic databases identified primary studies published in English up to March, 2014; of 33 eligible studies, three were cohort studies, 27 cross-sectional, and three case-control. Knowledge of and participation in screening was greater for breast cancer than for other cancers. Indigenous peoples tended to have less knowledge, less favourable attitudes, and a higher propensity to refuse screening than non-indigenous populations. The most common factors affecting knowledge, attitudes, and behaviours towards cancer screening included access to screening, knowledge about cancer and screening, educational attainment, perceived necessity of screening, and age. Greater understanding of knowledge, attitudes, and behaviours towards cancer screening in diverse indigenous cultures is needed so that culturally appropriate cancer prevention programmes can be provided.

To estimate the risk of late morbidity leading to hospitalization among young adult cancer 5-year survivors compared to the general population and to examine the long-term effects of demographic and disease-related factors on late morbidity, a retrospective cohort of 902 five-year survivors of young adult cancer diagnosed between 1981 and 1999 was identified from British Columbia (BC) Cancer Registry. A matched comparison group (N = 9020) was randomly selected from the provincial health insurance plan. All hospitalizations until the end of 2006 were determined from the BC health insurance plan hospitalization records. The Poisson regression model was used to estimate the rate ratios for late morbidity leading to hospitalization except pregnancy after adjusting for sociodemographic and clinical risk factors. Overall, 455 (50.4%) survivors and 3,419 (37.9%) individuals in the comparison group had at least one type of late morbidity leading to hospitalization. The adjusted risk of this morbidity for survivors was 1.4 times higher than for the comparison group (95% CI = 1.22-1.54). The highest risks were found for hospitalization due to blood disease (RR = 4.2; 95% CI = 1.98-8.78) and neoplasm (RR = 4.3; 95% CI = 3.41-5.33). Survivors with three treatment modalities had three-fold higher risk of having any type of late morbidity (RR = 3.22; 95% CI = 2.09-4.94) than the comparators. These findings emphasize that young adult cancer survivors still have high risks of a wide range of late morbidities.
