Long-Term and Latent Side Effects of Specific Cancer Types

Understanding Return to Work After a Cancer-Related Sickness Absence. Perceptions of Barriers and Facilitators Among all Relevant Stakeholders

PURPOSE

The aim of this study was to examine the themes acting as barriers or facilitators, from diagnosis and sickness absence (SA) to RTW and work retention, after a cancer-related SA from the perspectives of all stakeholders in the Spanish setting.

METHODS

Descriptive qualitative approach with a socio-constructivist perspective. Theoretical sampling was carried out until saturation. Six discussion groups (4-8 people/group) were conducted: three groups of people with a cancer-related SA in Catalonia (Spain), one with oncology care professionals, and two with company representatives. An additional individual interview was conducted with a primary care physician. The sessions were held virtually and were recorded, transcribed verbatim, and analyzed using thematic analysis and mixed coding.

RESULTS

Barriers to RTW and work retention detected by stakeholders included insufficient information and guidance on the impact of cancer on work and SA management, lack of general knowledge and recognition of side effects, lack of consideration of job tasks by medical tribunals, and working in precarious employment. Facilitators included workplace support, psycho-oncologists, patient associations, and working for a public company.

CONCLUSIONS

Both work interruption due to an SA and RTW, are key moments for determining cancer survivors' work retention. We found a general perception of lack of involvement of the social security system, companies, and health professionals in Spain in the impact of cancer on work.

IMPLICATIONS FOR CANCER SURVIVORS

Integrating the work sphere in cancer care from the beginning of cancer treatment, and by all stakeholders, could facilitate successful future RTW.

Associations Between Cancer-Related Fatigue and Healthcare Use During Cancer Follow-Up Care: A Survey-Administrative Health Data Linkage Study

Little is known about the impacts of fatigue after cancer treatment, including whether cancer-related fatigue impacts people's use of healthcare. This study sought to examine how cancer-related fatigue impacts healthcare use after completing cancer treatment. A population-based survey was administered in Nova Scotia, Canada, to examine survivors' experiences and needs after completing cancer treatment. Respondents included survivors of breast, melanoma, colorectal, prostate, hematologic, and young adult cancers who were 1-3 years post-treatment. Survey responses were linked to cancer registry, physicians' claims, hospitalization, and ambulatory care data. Data were analyzed descriptively and using regression models. The final study cohort included 823 respondents. Younger respondents reported higher levels of cancer-related fatigue compared to older respondents. More females than males reported cancer-related fatigue. Upon adjusted analyses, those with cancer-related fatigue had lower odds of being discharged to primary care for their cancer-related follow-up (odds ratio = 0.71, p = 0.029). Moreover, those with cancer-related fatigue had 19% higher primary care use (incidence rate ratio = 1.19, p < 0.0001) and 37% higher oncology use (incidence rate ratio = 1.37, p < 0.016) during the follow-up period compared to those without cancer-related fatigue. Providers (oncology and primary care) may require additional support to identify clinically relevant fatigue and refer patients to appropriate resources and services.

Barriers and facilitators to cancer rehabilitation for patients with head and neck or lung cancer-a scoping review mapping structural and healthcare professionals' perspectives

PURPOSE

Rehabilitation can positively affect quality of life, functional status, and physiological status for patients with head and neck or lung cancer. However, barriers and facilitators regarding access, referral, and participation in rehabilitation have not been outlined in the literature either from a healthcare professional or from a structural perspective. Therefore, the objective of this paper was to identify and map barriers and facilitators from structural and healthcare professionals' perspectives in relation to access, referral, and participation in rehabilitation for patients with head and neck or lung cancer.

MATERIALS AND METHODS

Two systematic searches were conducted in five databases mapping peer-reviewed research literature.

RESULTS

In total, 17 studies of 3918 potential sources were included. Seven themes were identified. Four themes concerned access: Understanding Patients' Resources; Collaboration Determining Access; Education, Knowledge, and Evidence Impact Access to Rehabilitation; and Resources Affecting Availability to Rehabilitation Services. Two themes concerned referral: Referral Criteria; and Elements Affecting Referral Pathway. One theme concerned participation: Factors Influencing Participation.

CONCLUSION

From structural and healthcare professionals' perspectives, barriers and facilitators impact access, referral and participation in rehabilitation. However, the findings on facilitators were limited; only one theme addressed participation and two findings concerned patients with low socioeconomic status.IMPLICATIONS FOR REHABILITATIONHealthcare professionals should be mindful that a diverse array of barriers and facilitators may impact the rehabilitation pathway for patients with head, neck, and lung cancer.Engagement by healthcare professionals and structural initiatives are needed to ensure comprehensive access to information concerning rehabilitation options.Local guidelines should be developed to prescribe methods for informing and guiding patients towards suitable rehabilitation options.It is important that healthcare professionals take the individual patient's resources into account when navigating aspects of access, referral, and participation in rehabilitation.

Financial distress and medical financial hardship among young adult survivors of blood cancer

BACKGROUND

The long-term financial impact of cancer care has not been adequately addressed in young adults. As part of a remote intervention study, we describe medical financial distress and hardship among young adult survivors of blood cancer at study entry.

METHODS

Young adults were recruited from 6 US hospitals. Using a Research Electronic Data Capture link, young adults confirmed their eligibility-namely, currently 18 to 39 years of age, blood cancer diagnosis 3 or more years ago, off active treatment, and not on parent's insurance. Following consent, the baseline assessment was sent. The primary outcome measure, the Personal Financial Wellness Scale, measured financial distress (scored as severe, 1-2; high, 3-4; average, 5-6; and low to no, 7-10). Medical financial hardship encompassed material hardship, psychological impact, and coping behaviors. Descriptive summary statistics and linear regression were used.

RESULTS

Among the 126 participants, 54.5% came from minority racial or ethnic groups. Median time since diagnosis was 10 years (interquartile range = 6-16 years), with 56% having received a diagnosis when they were between 18 and 39 years of age. The overall mean (standard deviation) Personal Financial Wellness Scale score was 5.1 (2.4), but 49% reported severe or high distress. In multivariable analysis, female sex, Hispanic ethnicity, and lower income were strongly associated with worse Personal Financial Wellness Scale scores. Among participants with severe financial distress (n = 26), 72% reported 2 or more household material hardships, had worse scores across all psychological domains, and altered survivorship care because of cost (68%).

CONCLUSIONS

Nearly half of long-term young adult cancer survivors reported severe or high levels of financial distress. Individuals with severe or high distress also reported more medical financial hardship than other participants. This finding highlights the need for ongoing financial intervention in this vulnerable population.

Influence of the anchor system on body sway in women affected and not affected by lymphedema secondary to breast cancer: A cross-sectional study

BACKGROUND

Postural control is an essential ability for functional independence modified by therapeutic approaches and morbidities secondary to breast cancer. The anchor system enables additional haptic perception of body position in front of the support base and can be used alone or in conjunction with sensorimotor training.

RESEARCH QUESTION

What is the influence of the anchor system, through different manual contacts on the upper limb, on body sway in women affected and not affected by lymphedema secondary to breast cancer treatment?

METHODS

Cross-sectional study involving 60 women homogeneously distributed to the group affected by lymphedema (GAL), with a mean age of 62.53 (SD = 12.54) years and upper limb volume difference (ULVD = Ipsilateral - Contralateral) of 636.21 (SD = 387.94) cm3, and group not affected by lymphedema (GNAL), with a mean age of 57.24 (SD = 11.43) years and ULVD of -8.91 (SD = 121.72) cm3. Baropodometry was used to assess body sway, through the presence and absence of the visual sense, associated with different manual contacts of the anchor system designated absence, simulation of use, unilateral and bilateral contact. The Shapiro-Wilk and Student's T-tests with Bonferroni Post-Hoc were used in the statistical analysis (p ≤ 0.05).

RESULTS

The GAL expressed non-significant values compared to the GNAL in the absence of visual sense and non-use of the anchor system. The unilateral contact of the anchor system on the preferred upper limb in the presence of the visual sense, and bilateral contact of the anchor system in the presence and absence of the visual sense promoted a significant reduction of body sway in both groups.

SIGNIFICANCE

In breast cancer survivors, the anchor system with bilateral contact effectively maintains postural control, regardless of the visual sense and the volume of the upper limb.

Cardiovascular Toxicity in Cancer Therapy: Protecting the Heart while Combating Cancer

PURPOSE OF REVIEW

This review explores the cardiovascular toxicity associated with cancer therapies, emphasizing the significance of the growing field of cardio-oncology. It aims to elucidate the mechanisms of cardiotoxicity due to radiotherapy, chemotherapy, and targeted therapies, and to discuss the advancements in human induced pluripotent stem cell technology (hiPSC) for predictive disease modeling.

RECENT FINDINGS

Recent studies have identified several chemotherapeutic agents, including anthracyclines and kinase inhibitors, that significantly increase cardiovascular risks. Advances in hiPSC technology have enabled the differentiation of these cells into cardiovascular lineages, facilitating more accurate modeling of drug-induced cardiotoxicity. Moreover, integrating hiPSCs into clinical trials holds promise for personalized cardiotoxicity assessments, potentially enhancing patient-specific therapeutic strategies. Cardio-oncology bridges oncology and cardiology to mitigate the cardiovascular side-effects of cancer treatments. Despite advancements in predictive models using hiPSCs, challenges persist in accurately replicating adult heart tissue and ensuring reproducibility. Ongoing research is essential for developing personalized therapies that balance effective cancer treatment with minimal cardiovascular harm.

A protocol for the longitudinal investigation of cancer related fatigue in head and neck cancer with an emphasis on the role of physical activity

BACKGROUND AND AIM

Cancer related fatigue significantly impairs the ability to undertake sustained physical activity across the domains of daily living, work and recreation. The purpose of this study is to monitor cancer related fatigue and the factors affected or caused by it for 12 months in head and neck cancer patients following their diagnosis. Their perceptions of how fatigue might affect their activity levels in addition to identifying avenues to improve engagement with physical activity will be also explored.

METHODS

A single centre longitudinal mixed-methods study will be conducted. Forty head and neck cancer patients will be recruited over 6 months following the confirmation of their treatment plan, after which fatigue and physical activity will be assessed at four time points over 12 months. Additionally, other factors which influence fatigue such as body composition, blood counts, systemic inflammation levels, haemoglobin concentration, thyroid function, sleep quality, cardiorespiratory fitness and upper and lower extremity strength will be measured to understand how the multifactorial problem of fatigue may evolve over time and influence physical activity levels. Semi-structured interviews will be conducted after treatment completion and at end of twelve months which will analyse the participants fatigue experiences, understand how their perceived fatigue may have impacted physical activity and report the factors which may improve engagement with physical activity during cancer. Quantitative data will be analysed and reported using standard descriptive statistics and post-hoc pairwise comparisons. The changes in outcome measures across time will be analysed using the MIXED procedure in SPSS software. Statistical significance will be accepted at p<0.05. Qualitative data will be analysed using the Interpretative Phenomenological Approach using the NVivo software.

DISCUSSION

The results from this study may help inform the planning and delivery of appropriately timed interventions for the management of cancer related fatigue.

Molecular Mechanisms of Anticarcinogenic Potential of Hydrocotyle umbellata and Its Major Components

Despite the development of several anticancer treatments, there remains a need for new drugs that can overcome resistance and reduce side effects. While the medicinal herb Hydrocotyle umbellata (H. umbellata) has been used to relieve pain and inflammation, its antitumor properties have not yet been explored. In this study, we investigated the anticarcinogenic potential of H. umbellata extract (HUE) and its major components, as well as the underlying molecular mechanisms. Our results showed that HUE inhibited the growth of various tumor cell lines, including B16F10, without affecting non-cancer cells. Furthermore, HUE was effective in treating and preventing tumor growth in mice. Our mechanistic studies revealed that HUE inhibited cellular respiration, thereby reducing tumor cell proliferation. When combined with 2-deoxy-D-glucose, HUE demonstrated an enhanced anticancer effect by increasing the rate apoptosis. Analysis of the ethyl acetate and n-butanol fractions of HUE identified 1,3,4-trihydroxy-2-butanyl-α-d-glucopyranoside and caffeoylquinic acid derivatives as the major components responsible for the observed anticancer effects. In conclusion, our findings suggest that HUE and its two major components have the potential to be developed as effective therapeutic agents for a wide range of tumors by targeting cancer cell metabolism.

Chronic fatigue in long-term survivors of head and neck cancer treated with radiotherapy

BACKGROUND

There is lack of evidence on chronic fatigue (CF) following radiotherapy (RT) in survivors of head and neck cancer (HNC). We aimed to compare CF in HNC survivors > 5 years post-RT with a reference population and investigate factors associated with CF and the possible impact of CF on health-related quality of life (HRQoL).

MATERIAL AND METHODS

In this cross-sectional study we included HNC survivors treated in 2007-2013. Participants filled in patient-reported outcome measures and attended a one-day examination. CF was measured with the Fatigue Questionnaire and compared with a matched reference population using t-tests and Cohen's effect size. Associations between CF, clinical and RT-related factors were investigated using logistic regression. HRQoL was measured with the EORTC Quality of Life core questionnaire.

RESULTS

The median age of the 227 HNC survivors was 65 years and median time to follow-up was 8.5 years post-RT. CF was twice more prevalent in HNC survivors compared to a reference population. In multivariable analyses, female sex (OR 3.39, 95 % CI 1.82-6.31), comorbidity (OR 2.17, 95 % CI 1.20-3.94) and treatment with intensity-modulated RT (OR 2.13, 95 % CI 1.16-3.91) were associated with CF, while RT dose parameters were not. Survivors with CF compared to those without, had significantly worse HRQoL.

CONCLUSIONS

CF in HNC survivors is particularly important for female patients, while specific factors associated with RT appear not to play a role. The high CF prevalence in long-term HNC survivors associated with impaired HRQoL is important information beneficial for clinicians and patients to improve patient follow-up.

A systematic review and meta-analysis of e-cigarette use among cancer survivors

PURPOSE

We conducted a systematic review and meta-analysis to determine the use of e-cigarettes among cancer survivors, factors associated with their use, and prevalence of e-cigarette use as a quit attempt.

METHODS

We searched five electronic databases until June 2022. Two authors independently selected studies, appraised their quality, and collected data.

RESULTS

Twenty-three publications from eight data sources (national surveys) met our eligibility criteria. The pooled rate of lifetime e-cigarette use among cancer survivors was 15% (95% CI 6-27%); current use was 3% (95% CI 0-8%). Among survivors who currently used traditional cigarettes, 63% (95% CI 57-69%) also used e-cigarettes. The reported rates of weighted lifetime e-cigarette use differed between age groups (18-44 years, up to 46.7%; 45-64, up to 27.2%; ≥65, up to 24.8%). Nine publications reported factors associated with lifetime e-cigarette use (i.e., active use of traditional cigarettes; heavy drinking; poor mental health; younger age; being male, non-Hispanic White, or single; having less than high school education or income ≤$25,000 USD; and living in the South regions of the US or urban areas). E-cigarettes were used as a quit resource by 75% of survivors reporting dual use of electronic and traditional cigarettes (95% CI 63%, 85%).

CONCLUSION

More than two-thirds of survivors currently using traditional cigarettes also use e-cigarettes. Higher use rates of e-cigarettes were reported among young cancer survivors compared to older survivors. Future studies are needed to assess the impact of e-cigarettes on long-term health and improve screening of smoking behaviors.

IMPLICATIONS FOR CANCER SURVIVORS

Our study provides an overview of the prevalence of e-cigarette use and sociodemographic risk factors associated with e-cigarette use among cancer survivors. The findings can assist providers in supporting attempts to quit among cancer survivors.

Caregiver perceptions of child heath behaviors and weight during treatment for acute lymphoblastic leukemia

BACKGROUND

Changes in health behaviors and weight are common during the early phases of pediatric acute lymphoblastic leukemia treatment, and may negatively impact treatment tolerability. Given that ALL is most prevalent in children, caregivers play an essential role in shaping health behaviors during treatment. This study presents a qualitative analysis of semi-structured interviews with caregivers of youth in the early phases of ALL treatment.

PROCEDURE

Caregivers (N = 17, 95% female) of a child (M age = 6.76 years) diagnosed with ALL and on treatment for less than 1 year (M = 8.7 months since diagnosis) completed a semi-structured interview about perceptions of their child's nutrition, physical activity, sedentary time, and weight during ALL treatment. Thematic analysis followed Braun and Clark's six-step framework (2006). Two coders established reliability (alpha = .88) and used a multi-pass coding system to extract themes.

RESULTS

Caregivers' concerns around their child's weight during ALL treatment primarily centered around avoiding malnutrition. Weight gain during treatment was less of a concern and often viewed as protective. Caregivers reported encouraging their child to eat palatable, calorie-dense foods to mitigate risk for weight loss. Caregivers also expressed concern that children were less active and more sedentary due to treatment-related pain. Caregivers discussed health behaviors during treatment as being child-directed, rather than parent- or provider-directed.

CONCLUSION

Future interventions may consider strategies to engage in joint parent-child decisions and caregiver education around risks of excessive weight gain during treatment. Interventions should include anticipatory guidance and aim to support parents in developing skills to support their child's health behaviors during treatment.

Cancer survivorship: understanding the patients' journey and perspectives on post-treatment needs

BACKGROUND

Cancer treatments have many adverse effects on patient's health leading to poor cardiorespiratory capacity, muscular- degeneration, fatigue, loss of strength and physical function, altered body-composition, compromised immune-function, peripheral neuropathy, and reduced quality of life (QOL). Exercise programs can significantly increase functional capacity when tailored to individual needs, thus improving health. Exercise interventions in cancer rehabilitation, when supported by appropriate nutrition can be effective in attaining a healthy weight and body-composition. The successful rehabilitation program should also include psycho-social education aimed to reduce anxiety and improve motivation.

METHODS

The current study aimed to collect information on the post-treatment needs of cancer patients including barriers and expectations facing them, their caregivers and their families through consultation in focus group interviews. Cancer survivors living in the Republic of Ireland were recruited from the University Hospital Galway, community-based cancer centres, cancer support groups and social media platforms to participate in the study and attend a focus group interview. The focus group discussions were designed to obtain information on the collective views of cancer survivors on relevant topics selected. The topics were developed in consultation with a patient and public involvement (PPI) group supporting the study. The topics list was circulated to all participants prior to the focus group. The interviews were audio recorded and transcribed verbatim. Focus group transcripts were analysed subjected to a thematic framework analysis using NVivo.

RESULTS

Thirty-six participants took part in 9 focus groups. Our analysis uncovered two main themes. The first theme 'cast adrift with no direction' was grouped into three sub-themes: everything revolves around treatment; panic and fear; and what exercise should I be doing? The second theme 'everybody is different' was clustered into two sub-themes: side effects get in the way; and personalised exercise program.

CONCLUSION

The study highlighted the lack of information and support needed by patients living with and beyond cancer. The study also highlighted the need for a personalised exercise programme designed to target the individual patient symptoms that would be ideal for the mitigation of long term symptoms and in improving QOL.

Barriers and facilitators to physical activity participation for child, adolescent, and young adult cancer survivors: a systematic review

PURPOSE

The aim of this systematic review is to explore and describe the barriers and facilitators to physical activity (PA) participation for child, adolescent, and young adult cancer survivors.

METHODS

MEDLINE, Embase, AMED, CINAHL, Cochrane, and Web of Science were searched for manuscripts published between January 2000 and February 2021. To be included in this review, studies had to report qualitative or quantitative data on barriers and facilitators to PA participation in child (4 to < 10 years), adolescent (10 to 19 years), and young adult (> 19 to < 40 years) cancer survivors. Six independent reviewers assessed methodological quality using the Mixed Methods Appraisal Tool (MMAT-version 18) in duplicate.

RESULTS

Fifteen studies were included in this systematic review. Fatigue and psychological factors were the most prevalent barriers shared between children, adolescents, and young adults. Support from others was a shared facilitator between age groups.

CONCLUSION

Psychological barriers and social support are important to address in younger cancer survivors. Clinicians can use these findings to create exercise interventions to facilitate and overcome barriers to PA participation.

IMPLICATIONS FOR CANCER SURVIVORS

While PA is beneficial for cancer survivors of all ages, different barriers and facilitators to PA participation exist depending on a survivors age and life stage. Survivors should discuss PA with their healthcare team at all timepoints in the cancer treatment trajectory in order to gain the associated benefits during and after treatment.

Screening for Frailty Using the FRAIL Scale in Older Cancer Survivors: A Cross-sectional Comparison With the Fried Phenotype

OBJECTIVES

To examine the diagnostic performance of the FRAIL Scale for frailty screening with reference to the Fried phenotype and investigate its association with health outcomes in older cancer survivors.

DATA SOURCE

In this cross-sectional quantitative study, participants were post-treatment cancer survivors aged 65 or above. Measurements included the FRAIL Scale, Fried phenotype, Geriatric Depression Scale-15 item, Modified Barthel Inventory, and EORTC Core Quality of Life Questionnaire. Receiver operating characteristic curve analysis was performed to evaluate the diagnostic performance of the FRAIL Scale with reference to the Fried phenotype. Health outcomes associated with being frail as estimated by the FRAIL Scale and Fried phenotype were also examined using regressions.

RESULTS

Based on 293 older cancer survivors, the area under curve (AUC) of the FRAIL Scale was 0.79, and the optimal cut-off of 1 yielded a sensitivity of 92% and specificity of 41%. According to regression results, the FRAIL Scale was modified by adding an item on time since cancer treatment completion (AUC = 0.81), and using a cut-off of 2 for older cancer survivors, which yielded a sensitivity of 74% and specificity of 67%. The modified FRAIL Scale was associated with depressive symptoms, functional independence, fatigue, dyspnea, physical functioning, and role functioning.

CONCLUSIONS

The modified FRAIL Scale is proposed for use in older cancer survivors, and a cut-off of 2 should be used.

IMPLICATIONS FOR NURSING PRACTICE

The modified FRAIL Scale can serve as a brief screening tool for identifying frailty among older cancer survivors in practice.

Qualitative exploration of the perceptions of exercise in patients with cancer initiated during chemotherapy: a meta-synthesis

OBJECTIVE

To synthesise qualitative literature on (1) the perceptions of patients with cancer of participating in an exercise intervention while undergoing chemotherapy and (2) to inform and guide professionals in oncology and haematology practice.

DESIGN

A qualitative meta-synthesis based on Noblit and Hare's seven-step meta-ethnography.

DATA SOURCES

Six electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, EMBASE, PubMed, SCI-Expanded-SSCI and Scopus (final search June 2022) were used to identify qualitative literature containing individual or focus group interviews. The transparency of reporting for each study was assessed using the Consolidated criteria for Reporting Qualitative research checklist.

RESULTS

The search identified 5002 articles, 107 of which were selected for full-text review. Seventeen articles from five countries with patients undergoing chemotherapy during exercise interventions were included. Eleven articles were included in the meta-synthesis, which comprised 193 patients with various cancer diagnoses, disease stages, sexes and ages. Four main themes were identified: chemotherapy overpowers the body; exercise in battle with side effects; a break from gloomy thoughts; and a question of survivorship.

CONCLUSIONS AND IMPLICATIONS

The meta-synthesis emphasised that patients with cancer undergoing chemotherapy and simultaneously participating in exercise interventions may experience momentary relief from overwhelming side effects, even though full bodily recovery may be perceived as a distant prospect. The synthesis offers a sparse empirical basis for gaining insight into what patients experience existentially following exercise interventions. It is up to patients to independently apply the transfer value of exercise to their own existential circumstances.

Labour market participation after sickness absence due to cancer: a dynamic cohort study in Catalonia (Spain)

BACKGROUND

The consequences of cancer on working until retirement age remain unclear. This study aimed to analyse working life considering all possible labour market states in a sample of workers after sickness absence (SA) due to cancer and to compare their working life paths to those of a sample of workers without SA and with an SA due to other diseases.

METHODS

This was a retrospective dynamic cohort study among social security affiliates in Catalonia from 2012-2018. Cases consisted of workers with an SA due to cancer between 2012-2015 (N = 516) and were individually age- and sex-matched with those of affiliates with an SA due to other diagnoses and workers without an SA. All workers (N = 1,548, 56% women) were followed up from entry into the cohort until the end of 2018 to characterise nine possible weekly labour states. Sequence analysis, optimal matching, and multinomial logistic regression were used to identify and assess the probability of future labour market participation patterns (LMPPs). All analyses were stratified by sex.

RESULTS

Compared with workers with an SA due to cancer, male workers with no SA and SA due to other causes showed a lower probability of being in the LMPP of death (aRRR 0.02, 95% CI: 0.00‒0.16; aRRR 0.17, 95% CI: 0.06‒0.46, respectively) and, among women, a lower probability of permanent disability and death (aRRR 0.24, 95% CI: 0.10‒0.57; aRRR 0.39, 95% CI: 0.19‒0.83, respectively). Compared to workers with SA due to cancer, the risk of early retirement was lower among workers with no SA (women, aRRR 0.60, 95% CI: 0.22‒1.65; men, aRRR 0.64, 95% CI: 0.27‒1.52), although these results were not statistically significant.

CONCLUSIONS

Workplaces, many of which have policies common to all diagnoses, should be modified to the needs of cancer survivors to prevent an increasing frequency of early retirement and permanent disability when possible. Future studies should assess the impact of cancer on premature exit from the labour market among survivors, depending on cancer localisation and type of treatment.

What is an "early palliative care" intervention? A scoping review of controlled studies in oncology

INTRODUCTION

Early palliative care (EPC) has been advocated to improve cancer patients' health. However, EPC differs with regard to its elements and target groups. It is not known which parts of EPC contribute to effectiveness for which patient group. This scoping review provides a structured analysis of EPC interventions and outcome measures.

DESIGN

We searched EMBASE, MEDLINE, CINAHL, and CENTRAL up to February 2022. We included randomized controlled trials (RCT), nonrandomized trials, cohort studies (CS), and controlled before-after studies of EPC in adult patients in English, Dutch, and German language. Interventions had to be self-labeled as EPC. Screening and data extraction were performed by two raters. A structured analysis incorporating the TIDieR checklist was performed to describe the elements of the interventions.

RESULTS

We screened 2651 articles, resulting in 40 articles being included: 34 studies were RCT and six studies were CS with a mean sample size of 208 patients. Patients with pancreatic (n = 10) and lung cancer (n = 9) were most often included. Studies reported different reference points for the onset of EPC such as time after diagnosis of incurable cancer (n = 18) or prognosis (n = 9). Thirteen studies provided information about elements of EPC and eight studies about the control intervention. Most frequent elements of EPC were symptom management (n = 28), case management (n = 16), and advance care planning (ACP; n = 15). Most frequently reported outcome measures were health-related quality of life (n = 26), symptom intensity (n = 6), resource use, and the patient's mood (n = 4 each).

CONCLUSION

The elicited heterogeneity of ECP in combination with deficits of reporting are considerable barriers that should be addressed to further develop effective EPC interventions for different groups of cancer patients.

Losing a part of life: experiences of cancer survivors accessing treatment and sheltering in place during the COVID-19 pandemic

PURPOSE

To explore experiences of sheltering in place and accessing treatment during the initial stages of the COVID-19 pandemic among survivors with cancer receiving tyrosine kinase inhibitor (TKI) therapy.

METHODS

Participants from two pilot studies evaluating TKI therapy use in the Southeastern United States during the start of the COVID-19 pandemic (March 2020) were interviewed. Identical interview guides were used across both studies to assess participants' experiences accessing cancer treatment, sheltering in place, and coping during the COVID-19 pandemic. Digitally recorded sessions were transcribed professionally and checked for accuracy. Descriptive statistics were used to summarize participant sociodemographics, and a six-step thematic approach was used to analyze interview data and identify salient themes. Dedoose qualitative research software was used to manage and organize qualitative codes, themes, and memos.

RESULTS

Participants (n = 15) ranged from 43 to 84 years of age, and were mostly female (53.3%), married (60%), and survivors with hematologic malignancies (86.7%). The research team identified five salient themes: Participants followed pandemic guidelines, Variable impact on well-being, Common feelings of fear, anxiety and anger, No barriers to accessing therapy and medical care, and Faith and God as powerful forces for coping.

CONCLUSIONS

The conclusions of the study provide several implications for survivorship programs or clinics for supporting survivors who are taking chronic TKI therapy during COVID-19, including enhancement of current psychosocial support efforts for cancer survivors or development of new programs tailored to the unique needs of a survivor during a pandemic, such as focused coping strategies, modified physical activity programs, family/professional role changes, and access to safe public spaces.

Head and neck cancer treatment outcome priorities: A multi-perspective concept mapping study

With the increasing focus on patient-centred care, this study sought to understand priorities considered by patients and healthcare providers from their experience with head and neck cancer treatment, and to compare how patients' priorities compare to healthcare providers' priorities. Group concept mapping was used to actively identify priorities from participants (patients and healthcare providers) in two phases. In phase one, participants brainstormed statements reflecting considerations related to their experience with head and neck cancer treatment. In phase two, statements were sorted based on their similarity in theme and rated in terms of their priority. Multidimensional scaling and cluster analysis were performed to produce multidimensional maps to visualize the findings. Two-hundred fifty statements were generated by participants in the brainstorming phase, finalized to 94 statements that were included in phase two. From the sorting activity, a two-dimensional map with stress value of 0.2213 was generated, and eight clusters were created to encompass all statements. Timely care, education, and person-centred care were the highest rated priorities for patients and healthcare providers. Overall, there was a strong correlation between patient and healthcare providers' ratings (r = 0.80). Our findings support the complexity of the treatment planning process in head and neck cancer, evident by the complex maps and highly interconnected statements related to the experience of treatment. Implications for improving the quality of care delivered and care experience of head and cancer are discussed.

Association of the affordable care act with perceived health care quality of cancer survivors

BACKGROUND

The association between the Patient Protection and Affordable Care Act (ACA) and perceptions of health care quality of cancer survivors is not well established. The purpose of this study was to examine changes in perceived health care quality concurrent with the implementation of the ACA among cancer survivors relative to a non-cancer comparison group.

METHODS

We used cross-sectional data from the Health Information National Trends Survey (N = 30,542). Participants were considered cancer survivors if they had a diagnosis greater than five years before the interview. The pre-ACA period included the years 2008 through 2014. The post-ACA period included 2017 through 2020. Using difference-in-differences methods, we estimated the association of ACA implementation with perceived health care quality (measured from excellent to fair/poor) using propensity score-matched cancer survivors (n = 2298) and a non-cancer comparison group (n = 6669) with weighted logistic models.

RESULTS

There were similar distributions of perceptions of excellent, very good, good, and fair/poor health care quality regardless of cancer status or time-period. The pre-post ACA implementation difference of reporting excellent, very good and good health care quality (odds ratio [OR]: 1.0, 95% confidence interval [CI]: 0.83-1.19; OR: 0.98, 95% CI 0.83-1.19; and OR: 1.05, 95% CI: 0.87-1.28 respectively) compared to fair/poor was similar in cancer survivors relative to the non-cancer comparison group.

CONCLUSIONS

The initial implementation of the ACA appeared to have no effect on perceived overall health care quality reported by cancer survivors when compared to individuals without a history of cancer. Health care policies and domains which continue to support better patient-perceived care quality should be assessed in the cancer survivor population.

Behaviour change techniques used in lifestyle interventions that aim to reduce cancer-related fatigue in cancer survivors: a systematic review

BACKGROUND

Lifestyle interventions that target dietary and/or physical activity behaviours may impact cancer-related fatigue in cancer survivors. Changing lifestyle may be especially difficult for cancer survivors suffering from cancer-related fatigue. To increase effectiveness of lifestyle interventions, behaviour change techniques (BCTs) can be applied. The aim of this review is to systematically describe which BCTs are applied in lifestyle interventions targeting cancer-related fatigue among cancer survivors who finished primary treatment.

METHODS

PubMed, Scopus, PsycINFO, Cochrane Library and Web of Science were searched to identify randomised controlled trials (RCTs) of dietary and/or physical activity interventions targeting cancer-related fatigue in cancer survivors. The BCT taxonomy was used to code the BCTs that were applied in those interventions. BCTs that were reported in at least 25% of effective interventions were indicated as 'promising BCT', but only retained this classification when these BCTs were present in less than 25% of ineffective interventions.

RESULTS

Twenty-nine RCTs were identified, of which 17 were effective in reducing cancer-related fatigue. The most frequently applied BCTs were Goal setting (behaviour), Instruction on how to perform the behaviour, Demonstration of the behaviour, Behavioural practice/rehearsal, and Credible Source. The BCT 'Generalisation of the target behaviour' was identified as promising. These results should be interpreted with caution as only three studies screened their participants on level of cancer-related fatigue and most studies focused only on physical activity. Furthermore, many studies did not include a measure for actual behaviour change and had no follow-up period after the intervention ended.

CONCLUSIONS

There is a need for studies that screen their participants on level of cancer-related fatigue and a need for studies that focus more on dietary behaviours as a possible intervention to reduce fatigue. Also, studies should include follow-up timepoints after the interventions ends to examine long-term behaviour change. Future lifestyle interventions should describe interventions in detail to allow for easier coding of BCTs, and report on actual behaviour change following the intervention. Interventions may apply the BCT 'Generalisation of the target behaviour' to incorporate lifestyle behaviours in daily life. This may increase the chance that interventions will effectively reduce cancer-related fatigue.

Modeling of oncolytic viruses in a heterogeneous cell population to predict spread into non-cancerous cells

New cancer treatment modalities that limit patient discomfort need to be developed. One possible new therapy is the use of oncolytic (cancer-killing) viruses. It is only recently that our ability to manipulate viral genomes has allowed us to consider deliberately infecting cancer patients with viruses. One key consideration is to ensure that the virus exclusively targets cancer cells and does not harm nearby non-cancerous cells. Here, we use a mathematical model of viral infection to determine the characteristics a virus would need to have in order to eradicate a tumor, but leave non-cancerous cells untouched. We conclude that the virus must differ in its ability to infect the two different cell types, with the infection rate of non-cancerous cells needing to be less than one hundredth of the infection rate of cancer cells. Differences in viral production rate or infectious cell death rate alone are not sufficient to protect non-cancerous cells.

Self-reported symptoms among cancer survivors in the Women's Health Initiative (WHI) Life and Longevity after Cancer (LILAC) cohort

PURPOSE

Due to cancer survivors living longer and morbidity associated with cancer treatments, it is necessary to understand symptoms experienced by cancer survivors. This study will analyze the symptom burden among a large cohort of survivors across multiple cancer sites.

METHODS

Data from the Women's Health Initiative (WHI) Life and Longevity After Cancer (LILAC) study were used to examine the symptom burden of older cancer survivors. Poisson regression with robust standard errors was utilized to determine differences in symptoms by cancer site, treatment, and other covariates.

RESULTS

The most frequently reported symptoms among cancer survivors were fatigue (15.8%) and feeling sad or depressed (14.1%). Multivariable analyses indicated that more symptoms were reported among survivors who were younger (p = 0.002), divorced or separated (p = 0.03), and had a combination of public and private insurance (p = 0.01). Survivors who received chemotherapy (p < 0.001), radiation (p = 0.01), or hormone therapy (p = 0.02) reported more symptoms than survivors who did not receive these treatments. Survivors diagnosed with cancer < 5 years ago reported fewer symptoms than longer-term survivors, particularly those diagnosed > 10 years ago (p = 0.02).

CONCLUSIONS

Results indicate that common physical and psychological symptoms are reported across cancer types. Cancer survivors diagnosed with cancer 10 or more years ago reported more symptoms than those recently diagnosed. This suggests that symptoms may remain a problem for some survivors decades after their diagnosis.

IMPLICATIONS FOR CANCER SURVIVORS

Future research should focus on implementing active surveillance of cancer survivors. Healthcare providers and those who care for cancer survivors should understand that the symptom burden associated with cancer may persist even decades following diagnosis.

Noninvasive Red Laser Intervention before Radiotherapy of Triple-negative Breast Cancer in a Murine Model

Radiotherapy is a well-established cancer treatment; it is estimated that approximately 52% of oncology patients will require this treatment modality at least once. However, some tumors, such as triple-negative breast cancer (TNBC), may present as radioresistant and thus require high doses of ionizing radiation and a prolonged period of treatment, which may result in more severe side effects. Moreover, such tumors show a high incidence of metastases and decreased survival expectancy of the patient. Thus, new strategies for radiosensitizing TNBC are urgently needed. Red light therapy, photobiomodulation, has been used in clinical practice to mitigate the adverse side effects usually associated with radiotherapy. However, no studies have explored its use as a radiosensitizer of TNBC. Here, we used TNBC-bearing mice as a radioresistant cancer model. Red light treatment was applied in three different protocols before a high dose of radiation (60 Gy split in 4 fractions) was administered. We evaluated tumor growth, mouse clinical signs, total blood cell counts, lung metastasis, survival, and levels of glutathione in the blood. Our data showed that the highest laser dose in combination with radiation arrested tumor progression, likely due to inhibition of GSH synthesis. In addition, red light treatment before each fraction of radiation, regardless of the light dose, improved the health status of the animals, prevented anemia, reduced metastases, and improved survival. Collectively, these results indicate that red light treatment in combination with radiation could prove useful in the treatment of TNBC.

Premature senescence and cardiovascular disease following cancer treatments: mechanistic insights

Cardiovascular disease (CVD) is a leading cause of morbidity and mortality, especially among the aging population. The "response-to-injury" model proposed by Dr. Russell Ross in 1999 emphasizes inflammation as a critical factor in atherosclerosis development, with atherosclerotic plaques forming due to endothelial cell (EC) injury, followed by myeloid cell adhesion and invasion into the blood vessel walls. Recent evidence indicates that cancer and its treatments can lead to long-term complications, including CVD. Cellular senescence, a hallmark of aging, is implicated in CVD pathogenesis, particularly in cancer survivors. However, the precise mechanisms linking premature senescence to CVD in cancer survivors remain poorly understood. This article aims to provide mechanistic insights into this association and propose future directions to better comprehend this complex interplay.

Mathematical Modeling of Oncolytic Virus Therapy Reveals Role of the Immune Response

Oncolytic adenoviruses (OAds) present a promising path for cancer treatment due to their selectivity in infecting and lysing tumor cells and their ability to stimulate the immune response. In this study, we use an ordinary differential equation (ODE) model of tumor growth inhibited by oncolytic virus activity to parameterize previous research on the effect of genetically re-engineered OAds in A549 lung cancer tumors in murine models. We find that the data are best fit by a model that accounts for an immune response, and that the immune response provides a mechanism for elimination of the tumor. We also find that parameter estimates for the most effective OAds share characteristics, most notably a high infection rate and low viral clearance rate, that might be potential reasons for these viruses' efficacy in delaying tumor growth. Further studies observing E1A and P19 recombined viruses in different tumor environments may further illuminate the extent of the effects of these genetic modifications.

Effectiveness of Digital Health on the Quality of Life of Long-Term Breast Cancer Survivors: A Systematic Review

OBJECTIVES

To identify, critically appraise, and synthesize the available evidence on the effectiveness of digital health interventions to improve the quality of life or any of its four dimensions (physical, psychological, social, and spiritual) in women survivors of breast cancer who are in the extended or permanent survival stage.

DATA SOURCES

Systematic review-Four databases were searched: PubMed, CINAHL, PsycINFO, and Web of Science.

CONCLUSION

The clinical evidence shows a positive relationship or association between eHealth use and improved quality of life in breast cancer survivors at extended or permanent survival stage. However, the findings point to a deficit in the assessment of the social and spiritual domains that play a fundamental role in the quality of life of survivors.

IMPLICATION FOR NURSING PRACTICE

The findings found reflect implications of great value for nursing practice because these professionals are the main users of digital health tools to provide them to patients. Using these digital tools contributes to improving evidence-based practice and providing greater efficiency and effectiveness in the care of long-term cancer survivors.

The Effects of an Educational Intervention on Exercise Advice Behaviors of Thai Oncology Nurses

OBJECTIVE

To evaluate an educational intervention based on the Theory of Planned Behavior to increase oncology nurses' exercise advice behaviors.

METHODS

A single-group, quasi-experimental repeated measures design study was used with 124 oncology nurses in a Thai cancer institute. The educational intervention included preeducation self-directed activities for 1 hour, a 2-hour group education session, and posteducation outreach contact 1 week later. The outcome measures, including the Theory of Planned Behavior constructs, exercise knowledge, and self-reported exercise prescription behaviors, were collected at three time points: Time 1 (2 weeks preintervention), Time 2 (immediately preintervention), and Time 3 (2 weeks after the intervention).

CONCLUSION

Results indicated a statistically significant increase in scores after the intervention for all outcomes, including the Theory of Planned Behavior constructs (overall P value <.001), exercise knowledge (β = 2.99, P < .001), and exercise prescription behaviors: asking (odds ratio [OR] = 12.98, P < .001), assessing (OR = 6.20, P < .001), referring (OR = 4.10, P < .001), and writing exercise advice (OR = 11.52, P < .001). Additionally, verbal counseling behavior was performed by all participants, and therefore, the odds for verbal counseling were not reported. Structural equation modeling analysis demonstrated that attitudes and perceived behavioral control explained 41% of the variance in exercise advice intention. Perceived behavioral control and intention also explained 20% of the variance in self-reported exercise advice behaviors.

IMPLICATIONS FOR NURSING PRACTICE

Attitudinal and perceived behavioral control constructs should be a focus of attention to improve health care professionals' exercise advice behaviors. More focused research is required to examine whether patients engage in and follow the exercise advice provided by oncology nurses.

The role of community health advisors' cancer history in implementation and efficacy of a cancer control intervention

Community health advisors (CHAs) play a key role in promoting health in medically underserved communities, including in addressing cancer disparities. There is a need to expand the research on what characteristics make for an effective CHA. We examined the relationship between CHA personal and family history of cancer, and implementation and efficacy outcomes in a cancer control intervention trial. Twenty-eight trained CHAs implemented a series of three cancer educational group workshops for N = 375 workshop participants across 14 churches. Implementation was operationalized as participant attendance at the educational workshops, and efficacy as workshop participants' cancer knowledge scores at the 12-month follow-up, controlling for baseline scores. CHA personal history of cancer was not significantly associated with implementation, nor knowledge outcomes. However, CHAs with family history of cancer had significantly greater participant attendance at the workshops than CHAs without family history of cancer (P = 0.03) and a significant, positive association with male workshop participants' prostate cancer knowledge scores at 12 months (estimated beta coefficient = 0.49, P < 0.01) after adjusting for confounders. Findings suggest that CHAs with family history of cancer may be particularly suitable for cancer peer education, although further research is needed to confirm this and identify other factors conducive to CHA success.

Perceived burden and need for support among caregivers of cancer patients

BACKGROUND

The aims of this study were to examine (1) the perceived burden among caregivers and identify those in risk of high burden and (2) the need for support among caregivers and identify associated factors.

MATERIALS AND METHODS

Cancer patients who participated in an educational program at the Montebello Center (MBC) in Norway between May 2021 and February 2022 were asked to invite a caregiver to answer a questionnaire. The caregiving burden was assessed with the Caregivers Reaction Assessment (CRA) that consists of 24 questions scored from 1 (strongly disagree) to 5 (strongly agree), covering five domains. A mean sum score was calculated for each domain. Higher subscale scores indicate higher levels of burden, except for caregiver esteem where a high score indicates a low burden. Need for support was assessed with 13 questions.

RESULTS

Of 464 invitations, 185 caregivers responded (response 40%), median age was 58.0 years and 58% were male. Caregiver burden mean scores were: 2.6 (SD 1.03) for Impact on schedule, 2.1 (SD 0.79) for Lack of family support, 2.1 (SD 0.76) for Impact on health, 2.0 (SD 0.86) for Impact on finances, and 4.2 (SD 0.47) for Caregiver esteem. Female caregivers, younger, higher education, having comorbidities, caring for patients having recurrence of cancer, and shorter time since diagnosis were associated with higher burden measured on individual subscales of the CRA. Most reported needs were information about: cancer, late effects and rehabilitation services and support from peers and professionals to cope with the new situation. Younger, caregiver comorbidity and recurrence of cancer of the patient were associated with more needs.

CONCLUSIONS

The results indicate that caregivers of cancer patients participating at the MBC report moderate caregiver burden, however, numerous caregivers reported need for support within several areas. Our findings need to be confirmed in a larger unselected group.

The impact of PD-L1 as a biomarker of cancer responses to combo anti-PD-1/CTLA-4

Combination therapy of solid tumors with immune checkpoint inhibitors (ICIs) is a promising and rapidly evolving area of clinical research. Combo nivolumab-ipilimumab therapy has demonstrated potent efficacy in recent years, and PD-L1 expression profile has shown to play a key role in determining the most optimal immunotherapeutic regimen in advanced cancer patients. Here, the focus is over the impact of PD-L1 on combo nivolumab-ipilimumab in advanced solid cancer patients. Interpretations of this review indicate that patient responses to combo nivolumab-ipilimumab can be affected from different levels of PD-L1 expression states. A point required attention is the variations in responses among diverse cancer types or between different doses of the immunotherapy drugs. In general, higher rates of responses are seen with higher PD-L1 expression levels in many cancer types. This, however, is not coincided with survival of patients. Taken all into consideration, it could be asserted that considering PD-L1 as a solo biomarker may not be reliable for predicting clinical efficacy of combo nivolumab-ipilimumab. Thus, a search for other biomarkers or combination of PD-L1 with other factors may be considered for predicting patient responses.

Knowledge, Perception, and Skills, and Practices of Oncology Nurses in Cancer Survivorship Care: a Scoping Review

Survivorship care focuses on the well-being and quality of life of people affected by cancer. Oncology nurses play an essential role in survivorship care and must be equipped with the knowledge, skills, and competencies to provide survivorship care. This scoping review explored the existing literature on nurses' knowledge, perception, skills, or practices in delivering cancer survivorship care for adult cancer survivors. A scoping review was conducted through databases including PubMed, CINAHL, Scopus, Web of Science, and PsycInfo in February 2022, following the Joanna Briggs Institute methodology. Fourteen original research studies were included. Most of the studies were conducted in the USA and targeted oncology registered nurses. The studies primarily focused on the knowledge (n = 2, 14.3%), perception of responsibility (n = 8, 57.1%), and practice (n = 9, 64.3%) regarding survivorship care among oncology nurses, reporting widely varied results. Nine studies reported perceived skills, practice, and perceived barriers as the most used outcome measurements, while two assessed nurses' cancer survivorship care knowledge. The main gaps were discrepancies between oncology nurses' perceptions of responsibility and practices in delivering survivorship care. Lack of time, knowledge, and skills were reported as significant factors impeding survivorship care provision among oncology nurses. Limited research shows a gap in integrating knowledge into survivorship care practices among oncology nurses. Further studies are needed to develop educational programs on survivorship care to support the integration of survivorship care into oncology nurses' practice.

Nutrition care is an integral part of patient-centred medical care: a European consensus

While healthcare is becoming more patient-centred, evidence-based nutrition interventions are still not accessible to all patients with cancer. As nutrition interventions directly improve clinical and socioeconomic outcomes, patient-centred care is not complete without nutrition care. While awareness of the negative impact of malnutrition on clinical outcomes, quality of life, and functional and emotional wellbeing in cancer is growing, there is relatively poor awareness amongst patients, clinicians, policymakers, and payers that nutrition interventions -particularly those begun in the early stages of the disease course- are an effective method for improving such outcomes. The European Beating Cancer Plan recognises the need for a holistic approach to cancer but lacks actionable recommendations to implement integrated nutrition cancer care at member state level. When considering nutrition care as a human right, the impact on quality of life and functional status must be prioritized, as these may be equally as important to patients, especially in advanced cancer where improvements in clinical outcomes such as survival or tumour burden may not be attainable. We formulate actions needed at the regional and the European level to ensure integrated nutrition care for all patients with cancer. The 4 main Take Home Messages are as follows: 1. The goals of Europe's Beating Cancer Plan cannot be achieved without integrating nutrition across the cancer care continuum. 2. Malnutrition negatively impacts clinical outcomes and has socioeconomic consequences for patients and healthcare systems. 3. Championing integrating nutrition care into cancer care is therefore the duty and ethical responsibility of clinicians (Hippocratic Oath-primum non nocere) and 4. Nutrition care is a cost effective, evidence-based therapy.

Movement and health beyond care, MoviS: study protocol for a randomized clinical trial on nutrition and exercise educational programs for breast cancer survivors

BACKGROUND

Breast cancer (BC) is the most common invasive cancer in women, and exercise can significantly improve the outcomes of BC survivors. MoviS (Movement and Health Beyond Care) is a randomized controlled trial aimed to evaluate the potential health benefits of exercise and proper nutritional habits. This study aims to assess the efficacy of aerobic exercise training in improving quality of life (QoL) and health-related factors in high-risk BC.

METHODS

One hundred seventy-two BC survivor women, aged 30-70 years, non-metastatic, stage 0-III, non-physically active, 6-12 months post-surgery, and post chemo- or radiotherapy, will be recruited in this study. Women will be randomly allocated to the intervention arm (lifestyle recommendations and MoviS Training) or control arm (lifestyle recommendations). The MoviS training consists of 12 weeks of aerobic exercise training (2 days/week of supervised and 1 day/week of unsupervised exercise) with a progressive increase in exercise intensity (40-70% of heart rate reserve) and duration (20-60 min). Both arms will receive counseling on healthy lifestyle habits (nutrition and exercise) based on the World Cancer Research Fund International (WCRF) 2018 guidelines. The primary outcome is the improvement of the QoL. The secondary outcomes are improvement of health-related parameters such as Mediterranean diet adherence, physical activity level, flexibility, muscular fitness, fatigue, cardiorespiratory fitness (estimated maximal oxygen uptake), echocardiographic parameters, heart rate variability (average of the standard deviations of all 5 min normal to normal intervals (ASDNN/5 min) and 24 h very low and low frequency), and metabolic, endocrine, and inflammatory serum biomarkers (glycemia, insulin resistance, progesterone, testosterone, and high-sensitivity C-reactive protein).

DISCUSSION

This trial aims to evaluate if supervised exercise may improve QoL and health-related factors of BC survivors with a high risk of recurrence. Findings from this project could provide knowledge improvement in the field of exercise oncology through the participation of a multidisciplinary team that will provide a coordinated program of cancer care to improve healthcare quality, improve prognosis, increase survival times and QoL, and reduce the risk of BC recurrence.

Breast Cancer: How Hippotherapy Bridges the Gap between Healing and Recovery-A Randomized Controlled Clinical Trial

BACKGROUND

Breast cancer is the most diagnosed women's cancer, and has a high survival rate. Despite great progress in detection and treatment, life reconstruction requires comprehensive cross-sectoral approaches between different disciplines and deeper consideration of the patient's challenges. Hippotherapy is an emerging specialized rehabilitation approach, performed by accredited health professionals and equine specialists, on specially trained horses via their movement, activating major paths for physical, mental, psychic and social reinforcement, and is synergistic to rehabilitative and supportive care.

METHODS

We conducted a randomized open, prospective, two-armed, controlled trial on the effectiveness of hippotherapy versus conventional supportive care on adult women with a diagnosis of breast cancer, after the period of primary treatment (surgery, chemotherapy, radiotherapy). The 6-month program included, in the treated group, an initial 1-week daily hippotherapy session, followed by three short 2-day sessions with an interval of 2 months between each, where the patients received conventional supportive care. The control group received 6 months of conventional supportive care. The primary end point was quality of life. Cognitive performances, fatigue, anxiety, depression, and body image were the secondary end points. Measurements were done through self-reported questionnaires.

RESULTS

We observed statistical differences in the evolution of the measured parameters over time between the two groups. The hippotherapy group showed a much faster, favorable and continuous improvement until the end of the program for each function assessed. The most striking improvements were observed in global quality of life, and fatigue, while breast cancer-specific quality of life, cognitive performance, anxiety and depression and body image showed a less marked but still statistically significant difference at the final post-treatment evaluation.

CONCLUSIONS

We demonstrate the therapeutic relevance of hippotherapy, a one-health approach, as a key initial stage after cancer diagnosis and treatment to foster recovery. Furthermore, hippotherapy has a strong impact on cancer treatments' efficiency and reconstruction of patient's life and ecosystem. This work reveals a layer of complexity that needs to be broadly considered.

Beliefs and interests in physical activity programs of cancer survivors and their romantic partners

PURPOSE

Physical activity is associated with improved health outcomes for cancer survivors and their romantic partners, yet it is unclear if joint exercise programs for survivor-partner dyads are acceptable. This study examined demographic, relationship, exercise, and cancer history correlates of survivors' and their romantic partners' couples-based exercise beliefs and their preferences for program designs.

METHODS

All participants (survivors n=209, partners n=155, couples n=143) completed an online survey. Correlations and linear regression analyses were used to examine correlates of participants' importance of and interest in couples-based exercise and their likelihood of joining a couples-based exercise program. Intraclass correlations estimated shared variance at the couple level.

RESULTS

Most participants believed that couples-based exercise was highly important (51.8%) and were interested in a couples-based exercise program (61.5%), but fewer survivors believed their partner would be interested or would likely join a couples-based program. Across all outcomes, partner support for exercise was most strongly associated with participants' couples-based exercise beliefs (r = 0.19-0.54, p<.05), and couples were significantly aligned in their beliefs (ρ=0.20-0.31, p<.01). Participants were interested in exercise programs involving exercising together (67.3%) as well as exercising separately while sharing activity data on an app or website (48.0%).

CONCLUSIONS

This novel understanding of couples-based exercise beliefs provides a strong foundation upon which future exercise programs may be designed for survivors and their romantic partners.

IMPACT FOR CANCER SURVIVORS

Survivors' adoption and maintenance of exercise may be enhanced by the inclusion of romantic partners in exercise programs, and partners' inclusion is appealing to couples.

Interventions promoting cognitive function in patients experiencing cancer related cognitive impairment: A systematic review

OBJECTIVE

To examine the effect of interventions used to enhance cognitive function in patients experiencing cancer-related cognitive impairment.

METHODS

Studies including adults with a non-metastatic cancer who have received chemotherapy as part of their treatment and who have undergone interventions targeting cancer-related cognitive impairment were included. Studies involving patients with metastatic cancer and pre-existing cognitive deficits were excluded. Academic Search Complete, CINAHL Plus with full text, MEDLINE, Education Full Text, PsycARTICLES, PsycINFO, and ERIC were searched for studies published between January 2011 and September 2022. Data extraction and quality appraisal were conducted by two authors and cross-checked by the review team. Quality appraisal was conducted using 12 items from the Mixed Methods Appraisal Tool. Findings were presented narratively without meta-analysis.

RESULTS

Thirty-one studies were included. Interventions were categorised as integrative/complementary, cognitive behavioural therapy and compensatory strategies, exercise, psychoeducational/psychosocial, brain-training, and pharmacological. Over 100 instruments were identified, including the Functional Assessment of Cancer Therapy-Cognitive, Trail Making Tests-A and B, and instruments measuring secondary outcomes, including depression. Instruments often measured attention and concentration, language, memory, executive function, and/or patient-reported outcomes. Improvements were reported, with most studies measuring some or various aspects of cognitive functioning and very few studies measuring all domains of cognitive functioning, making it difficult to draw definitive conclusions about effectiveness.

CONCLUSIONS

Various interventions are available to treat cancer-related cognitive impairment. Outcome measurement was inconsistent and future research should prioritise using standardised measures. Current evidence, whilst not being definitive, suggests that certain interventions show greater promise than others, including cognitive behavioural therapy and brain training.

Health-related quality of life in the phase III ASCENT trial of sacituzumab govitecan versus standard chemotherapy in metastatic triple-negative breast cancer

BACKGROUND

The antibody-drug conjugate sacituzumab govitecan (SG) prolongs progression-free survival and overall survival in patients with refractory/relapsed metastatic triple-negative breast cancer (mTNBC). Here, we investigated its effect on health-related quality of life (HRQoL).

METHODS

This analysis was based on the open-label phase III ASCENT trial (NCT02574455). Adults with refractory/relapsed mTNBC who had received ≥2 prior systemic therapies (≥1 in the metastatic setting) were randomised 1:1 to SG or treatment of physician's choice (TPC; capecitabine, eribulin, vinorelbine, or gemcitabine). HRQoL was assessed on day 1 of each treatment cycle using the EORTC QLQ-C30. Score changes from baseline were analysed using linear mixed-effect models for repeated measures. Stratified Cox regressions evaluated time to first clinically meaningful change of HRQoL.

RESULTS

The analysis population comprised 236 patients randomised to SG and 183 to TPC. For global health status (GHS)/QoL, physical functioning, fatigue, and pain, changes from baseline were superior for SG versus TPC. Compared with TPC, SG was inferior regarding changes from baseline for nausea/vomiting and diarrhoea but non-inferior for other QLQ-C30 domains. Median time to first clinically meaningful worsening was longer for SG than for TPC for physical functioning (22.1 versus 12.1 weeks, P < 0.001), role functioning (11.4 versus 7.1 weeks, P < 0.001), fatigue (7.7 versus 6.0 weeks, P < 0.05), and pain (21.6 versus 9.9 weeks, P < 0.001).

CONCLUSIONS

SG was generally associated with greater improvements and delayed worsening of HRQoL scores compared with TPC. This supports the favourable profile of SG as an mTNBC treatment.

Case report: Early acute myocarditis after radiation therapy for breast cancer: A case presentation and review of literature

Breast cancer is the most commonly diagnosed cancer in women worldwide, and with the increased survival of patients by novel treatments, the frequency of complications of cancer treatments rises. Radiotherapy, especially on the chest wall, can damage different cardiac structures. Radiotherapy-induced cardiomyopathy mainly occurs over 10 years after breast cancer treatment; however, there is a gap in the literature on acute myocarditis following radiotherapy. Here, we present a 54-year-old woman who developed acute myocarditis shortly after 25 sessions of radiotherapy with 50 Gy of radiation, successfully diagnosed with the use of speckle tracking echocardiography (STE) and cardiac magnetic resonance (CMR), and responded to the medical treatment with relative clinical improvement until the final follow-up. This case suggests the necessity of detailed examination of patients after radiotherapy, not only for chronic occurrence of cardiomyopathy but also for acute myocarditis. Although STE and CMR resulted in accurate diagnosis, in this case, further studies are required to determine the diagnostic accuracy of these two imaging methods compared with other imaging modalities in such patients and investigate the best diagnostic tool and therapeutic approach for these patients.

Pain prevalence and characteristics in survivors of solid cancers: a systematic review and meta-analysis

PURPOSE

The latest systematic review on the prevalence of pain in cancer survivors was published 5 years ago. The current review aims to provide an extended overview on the prevalence of pain, pain mechanisms, pain characteristics, and assessment methods in cancer survivors.

METHODS

A systematic research was conducted on 17th of April 2020 using MEDLINE, Embase, Scopus, Web of Science, and Cochrane looking at studies from 2014 to 2020. Studies had to report pain prevalence rates in cancer survivors with a solid tumor who finished curative treatment at least 3 months ago. Methodological quality was assessed by two independent reviewers using the Joanna Briggs Institute quality appraisal tool. Characteristics of the included studies, participants and reported pain prevalence rates were extracted. The reported prevalence rates of the individual studies were pooled within a meta-analysis. Meta-regressions were performed to identify possible determinants of the pooled pain prevalence.

RESULTS

After deduplication, 7300 articles were screened, after which 38 were included in the meta-analysis. Risk of bias was rated low in 26 articles and moderate in 12 articles. The pooled pain prevalence was 47% (95%CI 39-55), with a heterogeneity of 98.99%.

CONCLUSION

This meta-analysis suggests that nearly half of cancer survivors report pain after completing curative treatment at least 3 months ago. However, substantial unexplained heterogeneity warrants cautious interpretation of these results. Meta-regression using cancer type, treatment location, pain measurement, and follow-up time as a covariate could not explain influencing factors explaining the high heterogeneity.

Effects of a Clinical Exercise Program on Health-Related Fitness and Quality of Life in Spanish Cancer Patients Receiving Adjuvant Therapy

OBJECTIVE

To report the feasibility and effectiveness of a newly developed clinical exercise program for improving maximal cardiorespiratory fitness in Spanish cancer patients receiving adjuvant chemotherapy or radiation. We also examined the effectiveness of the exercise program for improving maximal muscular strength, body composition, fatigue, and quality of life, and explored if the effectiveness varied based on selected patient characteristics.

DESIGN

The study was a single group implementation feasibility study using a pre-posttest design.

METHODS

Participants performed a 12-week, twice-weekly, supervised, multi-component exercise program during adjuvant therapy. Paired t-tests were used to assess pre-post changes, and analyses of covariance were used to compare effectiveness based on selected patient characteristics.

RESULTS

We had 100 cancer patients referred to the clinical exercise program of which 85 (85%) initiated the exercise program and 76 (89%) completed the post-intervention fitness assessment. Exercise significantly improved VO_2max by 4.8 mL/kg/minutes (P < .001, d = 0.74). Exercise also significantly improved chest strength (P < .001, d = 0.82), leg strength (P < .001, d = 1.27), lean body mass (P < .001, d = 0.11), skeletal muscle mass (P < .001; d = 0.09), fat mass (P < .001; d = 0.10), % body fat (P < .001; d = 0.17), quality of life (P = .0017; d = 0.41), and fatigue (P = .007; d = 0.46). Treatment modality, cancer type, and age affected some exercise responses, especially related to body composition changes.

CONCLUSIONS

A 12-week, supervised, multi-component exercise program was effective for improving health-related fitness and quality of life in Spanish cancer patients receiving adjuvant therapy. Our results show the benefits of incorporating clinical exercise programming into the supportive care of cancer patients receiving treatments.

A review of mechanisms underlying the protective effects of natural compounds against arsenic-induced neurotoxicity

Arsenic (As) is a toxic metalloid that is widely distributed in the earth's crust. People are continuously exposed to this toxicant in their food and drinking water. Inorganic arsenic occurs in two oxidation states, arsenite 3⁺ (iAs³⁺) and arsenate 5⁺ (iAs⁵⁺). The most toxic form is its trivalent form which interferes with the electron transfer cycle and induces overproduction of reactive oxygen species, leading to depletion of the antioxidant defense system, as well as altering fatty acid levels and mitochondrial action. Since arsenic crosses the blood-brain barrier, it can damage cells in different regions of the brain, causing neurological disorders through the induction of oxidative stress, inflammation, DNA damage, and cell death. Hydroxytyrosol, taurine, alpha-lipoic acid, ellagic acid, and thymoquinone have been shown to effectively alleviate arsenic-induced neurotoxicity. The protective effects are the result of the anti-oxidative and anti-inflammatory properties of the phytochemicals and in particular their anti-apoptotic function via the Nrf2 and PI3/Akt/SIRT1 signaling pathways.

Effects of structured involvement of the primary care team versus standard care after a cancer diagnosis on patient satisfaction and healthcare use: the GRIP randomised controlled trial

Background

The growing number of cancer survivors and treatment possibilities call for more personalised and integrated cancer care. Primary care seems well positioned to support this. We aimed to assess the effects of structured follow-up of a primary care team after a cancer diagnosis.

Methods

We performed a multicentre randomised controlled trial enrolling patients curatively treated for breast, lung, colorectal, gynaecologic cancer or melanoma. In addition to usual cancer care in the control group, patients randomized to intervention were offered a “Time Out consultation” (TOC) with the general practitioner (GP) after diagnosis, and subsequent follow-up during and after treatment by a home care oncology nurse (HON). Primary outcomes were patient satisfaction with care (questionnaire: EORTC-INPATSAT-32) and healthcare utilisation. Intention-to-treat linear mixed regression analyses were used for satisfaction with care and other continuous outcome variables. The difference in healthcare utilisation for categorical data was calculated with a Pearson Chi-Square or a Fisher exact test and count data (none versus any) with a log-binomial regression.

Results

We included 154 patients (control n = 77, intervention n = 77) who were mostly female (75%), mainly diagnosed with breast cancer (51%), and had a mean age of 61 (SD ± 11.9) years. 81% of the intervention patients had a TOC and 68% had HON contact. Satisfaction with care was high (8 out of 10) in both study groups. At 3 months after treatment, GP satisfaction was significantly lower in the intervention group on 3 of 6 subscales, i.e., quality (− 14.2 (95%CI -27.0;-1.3)), availability (− 15,9 (− 29.1;-2.6)) and information provision (− 15.2 (− 29.1;-1.4)). Patients in the intervention group visited the GP practice and the emergency department more often ((RR 1.3 (1.0;1.7) and 1.70 (1.0;2.8)), respectively).

Conclusions

In conclusion, the GRIP intervention, which was designed to involve the primary care team during and after cancer treatment, increased the number of primary healthcare contacts. However, it did not improve patient satisfaction with care and it increased emergency department visits. As the high uptake of the intervention suggests a need of patients, future research should focus on optimizing the design and implementation of the intervention.

Trial registration

GRIP is retrospectively (21/06/2016) registered in the ‘Netherlands Trial Register’ (NTR5909).

Effectiveness of HIIT in patients with cancer or cancer survivors: An umbrella and mapping review with meta-meta-analysis

OBJECTIVE

To assess the available evidence on the effectiveness of high-intensity interval training (HIIT) in addition to first-choice cancer treatment on cardiorespiratory fitness (CRF), quality of life (QoL), adherence, and adverse effects of HIIT in patients with cancer or cancer survivors.

METHODS

An umbrella review and meta-meta-analysis (MMA) was performed. A systematic search was conducted in MEDLINE, EMBASE, Cochrane Database, CINAHL, Scopus, SPORTDiscus, and Web of Science until August 2021. Article selection, quality assessment, and risk of bias assessment were performed by two independent reviewers. The MMA were performed with a random-effects model and the summary statistics were presented in the form of forest plot with a weighted compilation of all standardized mean differences (SMD) and corresponding 95% confidence interval (CI).

RESULTS

Seven systematic reviews were included. Regarding CRF, the addition of HIIT to cancer treatment showed statistically significant differences with a small clinical effect, compared with adding other treatments (SMD = 0.45; 95% CI 0.24 to 0.65). There was no significant difference when compared with adding moderate-intensity continuous training (MICT) (SMD = 0.23; 95% CI -0.04 to 0.50). QoL showed positive results although with some controversy. Adherence to HIIT intervention was high, ranging from 54% to 100%. Regarding adverse effects, most of the systematic reviews reported none, and in the cases in which they occurred, they were mild.

CONCLUSION

In conjunction with first-choice cancer treatment, HIIT has been shown to be an effective intervention in terms of CRF and QoL, as well as having optimal adherence rate. In addition, the implementation of HIIT in patients with cancer or cancer survivors is safe as it showed no or few adverse effects.

Quality of life in cancer survivorship: Sociodemographic and disease-related moderators

RATIONALE

To identify high-risk survivors in order to provide appropriate care.

PURPOSE

To analyse the quality of life (QOL) of cancer survivors using an instrument designed specifically for this population and considering different sociodemographic and disease-related characteristics as possible modulating variables.

METHODS

The Quality of Life in Adult Cancer Survivors (QLACS) was filled out by a large and heterogeneous sample of disease-free post-treatment Spanish cancer survivors (N = 1862).

RESULTS

QLACS scores were comparable to those obtained in other studies and indicative of worse QOL as a function of shorter elapsed time since the end of primary treatment. The best QOL was shown by prostate, and the worst by hematologic cancer survivors. Both systemic treatments (chemotherapy and hormone therapy) and the combination of radiotherapy and chemotherapy were associated with worse QOL. Likewise, younger age, female sex, unemployment status and not having a stable partner were associated with worse QOL.

CONCLUSION

Greater understanding of the QOL experienced by the already large and continuously growing population of cancer survivors is relevant for guiding both clinical practice and health policy. In addition, knowing the risk factors associated with worse QOL facilitates the development of targeted prevention programmes for those survivors who need it the most.

Case studies in physiology: Training adaptation in an elite athlete after breast cancer diagnosis

The aim of this study was to evaluate the capacity to return to competition of a 28-year-old female 400m hurdle elite athlete after a diagnosis of breast cancer. The study lasted 14 months after diagnosis. She was tested four times (T1-T4) to measure body mass (BM), body mass index (BMI), percentage of total fat mass (TFM%), total fat-free mass (TFFM%), bone mineral density (BMD), one-repetition maximum (1RM) and maximal power (MP) in bench-press and half-squat, maximum oxygen uptake, 400m dash and hurdles. T0 (baseline time) was established with values prior to diagnosis. BM and BMI increased from T0 to T1 (5.3% and 5.2%) and remained stable. BMD experienced no change. TFM% values decreased from T1 to T4 (3.5%). TFFM% values increased from T1 to T3 (0.9%). During T1-T2, the athlete presented a global decline from T0 in 1RM_Squat, 1RM_Bench, MP_Squat and MP_Bench (32.6%, 27.2%, 37.5%, 27.6%, respectively). Results during T3-T4 were also lower for these parameters from T0 (23.3%, 20.6%, 23.4%, 11%). During T1-T2, the VO_2max declined, compared to T0 (1.8% and 6.4%), showing a small increase at T3 (+1%) and reaching the lowest level at T4 (9%). During T1-T2, the time record of 400 m dash (8.3%) and hurdles (7.4%) increased. However, a slight improvement was found at T3 (1.3% and 0.6%, respectively). that exercise training improved body composition, maintained BMD and TFFM, but could not completely reverse the worsening of the cardiorespiratory, muscle strength and power, and running performance levels.

Nutrition Support & Intervention Preferences of Cancer Survivors

INTRODUCTION

Ascertaining cancer survivors' specific needs and preferences regarding nutrition information delivery is important in developing and designing future health interventions in oncology. This study aimed to explore the nutrition information needs of cancer survivors and their preferences regarding intervention delivery.

METHODS

The present study is a mixed-methods study comprising a cross-sectional survey and focus groups. Participants were eligible for inclusion if they were 18+years, living in Ireland with a cancer diagnosis and had completed treatment at least six months previous. Cancer support centres promoted the online survey on social media. Focus groups were conducted with twenty individuals.

RESULTS

The cohort (n=56) were predominantly female (n=50, 89.3%), breast cancer survivors (n=42, 75%). Seven (12.5%) had received nutrition advice from a dietitian. Most are interested in receiving nutrition advice (n=52, 92.9%), with variability in delivery mode. There was interest in improving sleep quality (n=35, 62.5%), making positive lifestyle changes (n=28, 50%) and accessing cancer-specific physical activity classes (n=27, 48.2%). The best time to deliver information was throughout the cancer journey (n=31, 55.4%). Time and motivation (n=15, 26.8%) were the main barriers. Facilitators were keeping healthy (n=42, 75%), and weight maintenance (n=31, 55.4%). Four themes emerged from thematic analysis; lack of nutrition guidance, an abundance of misinformation, one size does not fit all and dietitians as the preferred source of advice.

CONCLUSION

There is a desire for evidence-based nutrition advice and for dietitians to be integrated into cancer clinics and cancer survivorship care. This research guides future interventional work on the efficacy of nutrition interventions to improve cancer survivorship outcomes. This article is protected by copyright. All rights reserved.
