UNASSIGNED: Accidental falls among adult cancer survivors are a health concern. Falls impose economic burdens and detrimental consequences to cancer survivors. This review aimed to synthesize findings from published research to explore the relationship between falls and cancer diagnosis and treatment among cancer survivors.
UNASSIGNED: A scoping review was conducted using four databases (Medline, EMBASE, CINAHL, and Scopus) for the years 2001-2021. A total of 425 abstracts were identified after removing duplicates. A second search for the years 2022-2023 was completed where 80 abstracts were identified. Abstract screening, full-text review, and data extraction were conducted. Study characteristics and key findings were extracted from full texts. Descriptive numerical summaries were presented, and narrative analyses were performed.
UNASSIGNED: A total of 42 articles were included in the scoping review which demonstrated (1) an increased prevalence of falls among cancer survivors, (2) the presence of cancer-specific fall risk factors, (3) a lack of cancer-specific fall prediction tools, and (4) few fall prevention interventions as part of usual care among cancer survivors. Younger cancer survivors were underrepresented. Cancer survivors should be aware of their risk of falls, and health professionals should ensure that fall prevention is part of usual care.
Falls are associated with cancer survivorship and as there are more people living with and beyond cancer, falls are becoming more significant.There are cancer-specific fall risk factors relevant to cancer survivors which can contribute to increased fall risk.However, fall prevention may not be addressed in standard care for cancer survivors.This review suggests cancer-specific fall risk tools are needed, and that fall prevention should be part of oncologic care.

OBJECTIVE: This scoping review presents the preclinical and clinical data on the effects of high-dose radiation therapy (RT) on bone structure and function.
METHODS: An extensive PubMed search was performed for the relevant questions. The data were then synthesized into a comprehensive summary of the available relevant in-vitro, preclinical and clinical literature.
RESULTS: In-vitro studies of high-dose RT on cell cultures show considerable damage in the viability and functional capacity of the primary cells of the bones; the osteoclasts, the osteoblasts, and the osteocytes. In-vivo animal models show that high-dose RT induces significant morphological changes to the bone, inhibits the ability of bone to repair damage, and increases the fragility of the bone. Clinical data show that there is an increasing risk over time of damage to the bone, such as fractures, after high-dose RT.
CONCLUSIONS: These findings suggest that there may be a limit to the safe dose for single-fraction RT, and the long-term consequences of high-dose RT for the patients must be considered.

OBJECTIVE: This study tested the feasibility and efficacy of two iterations of a low-intensity online writing intervention, Expand Your Horizon (EYH), in improving body image and distress in a cancer population.
METHODS: In study 1 (3-session version of EYH), adult female cancer survivors (N = 201) were randomised to EYH, where they described their body functionality, or a creative writing control. Outcomes assessed at baseline and one-week follow-up included body appreciation, body dissatisfaction, and distress. In study 2 (1 session version of EYH), adult female cancer survivors (N = 65) were randomised to EYH or a neutral writing control. Outcomes (assessed at baseline, immediately post-intervention and one-week follow-up) included body appreciation, body functionality appreciation, body dissatisfaction and distress.
RESULTS: Study 1 experienced severe attrition; only 14 participants (7 %) completed the intervention and follow-up. Study 2 had higher retention, with 74 % completing the study. In study 2, while no significant differences emerged between EYH or control, both groups significantly improved immediately post-intervention across all outcomes. No differences were found at follow-up.
CONCLUSIONS: A single-session online writing intervention for cancer survivors appears to be more feasible than multi-session, however the efficacy of EYH for this population remains to be established.

BACKGROUND: Healthy eating and weight control are recommended for cancer survivors; however, dietary interventions are not routinely offered to them. This study aimed to assess the effects of dietary interventions on survival, nutritional status, morbidity, dietary changes, health-related quality of life (QOL), and clinical measures in cancer survivors.
METHODS: Searches were conducted from October 1, 2018 to November 21, 2011 in the Medline, EMBASE, CENTRAL, Emcare, and DARE electronic databases. We included randomized controlled trials (RCTs) that involved individuals diagnosed with cancer, excluding conference abstracts, case studies, other reviews, and meta-analyses, and screened the articles.
RESULTS: Eight studies were included in this meta-analysis. We observed significant improvements in QOL and clinical data in 3 of 6 studies and in one study, respectively, significant weight loss on anthropometry in 2 of 5 studies, and dietary improvement in 4 of 5 studies of adult cancer survivors. However, we did not observe any benefits of dietary intervention for cancer survivors with undernutrition.
CONCLUSIONS: Dietary interventions for adult cancer survivors might contribute to improving their nutritional status; however, further clarification requires a study that standardizes the intervention method. Furthermore, RCTs are required to determine the effects on cancer survivors with undernutrition.

The experience of childhood cancer (CC) could be a traumatic event that produces long-term emotional responses such as posttraumatic stress symptoms (PTSS) and posttraumatic growth (PTG) in survivors. The relationship between both PTSS and PTG is not clear in CC survivors. Assessing challenges to core beliefs and rumination could give information regarding the different paths that lead to traumatic responses. Thus, this study aims to identify childhood cancer survivors\' profiles from PTSS and PTG measures and to examine the pathways of relationships between PTSS and PTG, rumination, and challenge to core belief. Sixty-two CC survivors completed surveys on their childhood cancer experience, PTSS, PTG, challenge to core beliefs, and rumination. High PTG scores among childhood cancer survivors (Cluster 1), High PTSS scores among childhood cancer survivors (Cluster 2), and Childhood cancer survivors without changes (Cluster 3). Network analysis found that the challenge to core beliefs is the central point in the relationship between the variables, in a direct and positive relationship with PTG. We found an indirect path from challenge to core beliefs to PTSS, mediated by intrusive and deliberative ruminations. The combined findings suggested that there are different profiles related to trauma in CC survivors and the relationship between PTSS and PTG is mediated by the challenge to core beliefs and deliberative and intrusive rumination.

BACKGROUND: A large increase in new cancer cases is predicted worldwide, due to population growth, ageing and increased cancer risk. The age distribution of the Icelandic population is different from the other Nordic countries. The purpose of this study was to predict the number of new cancer cases in Iceland and other Nordic countries, and cancer survivors in Iceland, up to the year 2040.
METHODS: Information on cancer diagnoses was retrieved from The Icelandic Cancer Registry and information on population projections from Statistics Iceland. Well known methods for population projection were used to predict the number of new cancer cases in 2040, but adjusted to consider Icelandic circumstances. It is also based on more recent data than is accessible elsewhere. Three different methods were used to estimate the number of survivors in 2040 and are presented here for the first time.
RESULTS: In 2040 the predicted yearly average number of new cancer cases in Iceland will be up to 2,903 [95% CI 2.841-2.956], a 57% increase compared with 2022. The increase is higher in Iceland than in other Nordic countries (Norway 41%, Sweden 24%, Denmark 23%, Finland 21%). In 2022, the number of cancer survivors was around 17,500 and is predicted to be between 24,500 and 31,000 in 2040.
CONCLUSIONS: The main reason for the predicted increase of cancer cases and survivors is population trends, especially the ageing of the population. This expected increase in the number of cancer patients and improved survival will increase the demand for healthcare.

BACKGROUND: Cancer survivors are at higher risk of developing severe complications from influenza due to their compromised immune systems. Despite their increased vulnerability to influenza and the availability of vaccines, vaccine hesitancy among cancer survivors remains a significant public health concern in China.
METHODS: A multicenter, cross-sectional study was conducted among cancer survivors in China from January to December 2023. A total of 500 participants were recruited from the oncology departments of five tertiary hospitals. A structured, self-administered questionnaire was used to collect data on socio-demographic characteristics, cancer-related information, medical history, lifestyle factors, and influenza vaccine hesitancy. Univariate and multivariate logistic regression analyses were performed to identify factors associated with influenza vaccine hesitancy.
RESULTS: The response rate was 97.0% (485/500). Among all participants, 204 (42.06%) reported vaccine hesitancy. The results of multiple logistic regression showed that the longer the end of anti-cancer treatment, without a history of adverse vaccine reactions, and the level of family support played a protective role in vaccine hesitancy. Current rehabilitation status, frequent colds, not being informed by doctors about vaccination, exercising, lack of community vaccination education programs, and concerns about vaccine safety were risk factors that increase vaccine hesitancy.
CONCLUSIONS: A high proportion of cancer survivors in our study reported influenza vaccine hesitancy. Addressing concerns about vaccine safety, improving access to vaccination services, and enhancing doctor-patient communication are crucial for increasing influenza vaccine uptake in this vulnerable population.

BACKGROUND: In the USA, the prolonged effective survival of cancer population has brought significant attention to the rising risk of cardiometabolic morbidity and mortality in this population. This heightened risk underscores the urgent need for research into effective pharmacological interventions for cancer survivors. Notably, metformin, a well-known metabolic regulator with pleiotropic effects, has shown protective effects against cardiometabolic disorders in diabetic individuals. Despite these promising indications, evidence supporting its efficacy in improving cardiometabolic outcomes in cancer survivors remains scarce.
METHODS: A prospective cohort was established using a nationally representative sample of cancer survivors enrolled in the US National Health and Nutrition Examination Survey (NHANES), spanning 2003 to 2018. Outcomes were derived from patient interviews, physical examinations, and public-access linked mortality archives up to 2019. The Oxidative Balance Score was utilized to assess participants\' levels of oxidative stress. To evaluate the correlations between metformin use and the risk of cardiometabolic diseases and related mortality, survival analysis of cardiometabolic mortality was performed by Cox proportional hazards model, and cross-sectional analysis of cardiometabolic diseases outcomes was performed using logistic regression models. Interaction analyses were conducted to explore the specific pharmacological mechanism of metformin.
RESULTS: Among 3995 cancer survivors (weighted population, 21,671,061, weighted mean [SE] age, 62.62 [0.33] years; 2119 [53.04%] females; 2727 [68.26%] Non-Hispanic White individuals), 448 reported metformin usage. During the follow-up period of up to 17 years (median, 6.42 years), there were 1233 recorded deaths, including 481 deaths from cardiometabolic causes. Multivariable models indicated that metformin use was associated with a lower risk of all-cause (hazard ratio [HR], 0.62; 95% confidence interval [CI], 0.47-0.81) and cardiometabolic (HR, 0.65; 95% CI, 0.44-0.97) mortality compared with metformin nonusers. Metformin use was also correlated with a lower risk of total cardiovascular disease (odds ratio [OR], 0.41; 95% CI, 0.28-0.59), stroke (OR, 0.44; 95% CI, 0.26-0.74), hypertension (OR, 0.27; 95% CI, 0.14-0.52), and coronary heart disease (OR, 0.41; 95% CI, 0.21-0.78). The observed inverse associations were consistent across subgroup analyses in four specific cancer populations identified as cardiometabolic high-risk groups. Interaction analyses suggested that metformin use as compared to non-use may counter-balance oxidative stress.
CONCLUSIONS: In this cohort study involving a nationally representative population of US cancer survivors, metformin use was significantly correlated with a lower risk of cardiometabolic diseases, all-cause mortality, and cardiometabolic mortality.

Sarcopenia is prevalent among 11-25% of adult cancer survivors, depending on the cancer type, although the available data on post-treatment survivors in Japan are limited. If cancer patients develop cachexia, they may experience sustained weight loss as a result, ultimately leading to sarcopenia. Conversely, some patients experience post-treatment weight gain, resulting in sarcopenic obesity. Both sarcopenia and obesity elevate the risk of cardiovascular diseases and mortality; therefore, the importance of sarcopenia prevention and management is undeniable. The Guidelines for Exercise for Cancer Survivors recommend continued physical activity. Recent studies have reported the effectiveness of multimodal interventions, combining pharmacological, nutritional, and exercise approaches, necessitating multidisciplinary care for post-treatment sarcopenia. Innovative health interventions using mobile devices have also gained attention. However, studies on sarcopenia in post-treatment cancer survivors, especially those regarding exercise interventions, remain scarce in Japan, primarily due to limited insurance coverage for such post-treatment interventions and workforce challenges. It is clear that some cancer survivors have sarcopenia, which can lead to worse survival and secondary illness. While the benefits of exercise are clear, a comprehensive approach to sarcopenia is a further challenge for the future.

OBJECTIVE: Breast cancer treatment may interfere with work ability. Previous return-to-work studies have often focused on participants who were invited to participate after treatment completion. Participation varied, resulting in potential selection bias. This is a health-record-based study evaluating data completeness, both at baseline and one year after diagnosis. Correlations between baseline variables and return to work were also analyzed.
METHODS: This is a retrospective review of 150 relapse-free survivors treated in Nordland county between 2019 and 2022 (all-comers managed with different types of systemic treatment and surgery). Work status was assessed in the regional electronic patient record (EPR). A 65-years age cut-off was employed to define two subgroups.
RESULTS: At diagnosis, occupational status was assessable in all 150 patients. Almost all patients older than 65 years of age were retired (79%) or on disability pension for previously diagnosed conditions (19%). Data completeness one year after diagnosis was imperfect, because the EPR did not contain required information in 19 survivors. The majority of those ≤65 years of age at diagnosis returned to work. Only 14 of 88 patients (16%) did not return to work. Postoperative nodal stage was the only significant predictive factor. Those with pN1-3 had a lower return rate (68%) than their counterparts with lower nodal stage.
CONCLUSIONS: This pilot study highlights the utility and limitations of EPR-based research in a rural Norwegian setting, emphasizing the need for comprehensive, individualized interventions to support breast cancer survivors in returning to work. The findings underscore the importance of considering diverse sociodemographic and clinical factors, as well as the potential benefits of long-term, population-based studies to address these complex challenges.
