RESUMEN
PURPOSE: This paper aims to provide a comprehensive understanding of the need for continued development of symptom monitoring (SM) implementation, utilization, and data usage at the macro-, meso-, and micro-levels. METHODS: Discussions from a patient-reported SM workshop at the MASCC/ISSO 2022 annual meeting were analyzed using a macro-meso-micro analytical framework of cancer care delivery. The workshop categories "initiation and implementation, barriers to adoption and utilization, and data usage" were integrated for each level. RESULTS: At the macro-level, policy development could encourage data sharing and international collaboration, including the exchange of SM methods, supportive care models, and self-management modules. At the meso-level, institutions should adjust clinical workflow and service delivery and promote a thorough technical and clinical integration of SM. At the micro-level, SM should be individualized, with timely feedback for patients, and should foster trust and understanding of AI decision support tools amongst clinicians to improve supportive care. CONCLUSIONS: The workshop reached a consensus among international experts on providing guidance on SM implementation, utilization, and (big) data usage pathways in cancer survivors across the cancer continuum and on macro-meso-micro levels.

BACKGROUND: Patients with cancer are at increased risk of diabetes mellitus (DM). Previous studies on the prevalence and prognostic impact of DM in cancer survivors were limited by small sample sizes or short follow-up times. We aimed to compare the patient-reported prevalence of DM in long-term cancer survivors (LTCS), who survived 5 years or more after cancer diagnosis, with that in cancer-free controls, and to estimate the mortality risk among LTCS according to DM status. METHODS: Our population-based cohort comprised 6952 LTCS diagnosed with breast, colorectal, or prostate cancer between 1994 and 2004, recruited in 2008-2011 (baseline), and followed until 2019. A total of 1828 cancer-free individuals served as controls. Multivariable logistic regression was used to compare the prevalence of DM in LTCS and controls, and according to covariates at baseline. Mortality among LTCS according to DM was assessed by Cox proportional hazards regression. RESULTS: A total of 962 (13.8%) LTCS at baseline reported DM. Prevalence of DM in LTCS was not higher than in cancer-free controls, both at baseline (odds ratio, 0.80; 95% CI, 0.66-0.97) and at follow-up (odds ratio, 0.83; 95% CI, 0.67-1.04). Prevalence of DM in LTCS was associated with cancer site, older age, lower education, higher socioeconomic deprivation, higher body mass index, physical inactivity, other comorbidities, and poorer prognosis (adjusted hazard ratio [all-cause mortality] = 1.29; 95% CI, 1.15-1.44). CONCLUSION: DM in LTCS is prevalent, but not higher than in cancer-free population controls. Cancer survivors with concurrent DM are at a potentially higher risk of death. PLAIN LANGUAGE SUMMARY: Cancer and diabetes mellitus (DM) are two serious threats to global health. In our study, prevalence of DM in long-term cancer survivors who survived 5 years or more after cancer diagnosis was not higher than in cancer-free controls. This should not be interpreted as an indication of a lower risk of DM in cancer survivors. Rather, it highlights the potentially poor prognosis in diabetic cancer survivors. Therefore, keeping a continuous satisfactory DM and hyperglycemia management is essential during long-term cancer survivorship.

BACKGROUND: We explored the relationship between benefit finding (BF)/posttraumatic growth (PTG) at baseline and health-related quality of life (HRQOL) at baseline and follow-up in long-term cancer survivors (LTCS; ≥5-year post-diagnosis). MATERIALS AND METHODS: HRQOL was assessed in LTCS in 2009-2011 (5- to 16-year post-diagnosis, baseline) and re-assessed in 2018/2019 (14- to 24-year post-diagnosis, follow-up). BF and PTG were measured at baseline; mean scores were dichotomized into 'none-to-low' (<3) and 'moderate-to-high' (> =3). Linear regression models and linear mixed regression models were employed to assess the association of BF/PTG with HRQOL. RESULTS: Of the 6057 baseline participants, 4373 were alive in 2019, of whom 2704 completed the follow-up questionnaire. Cross-sectionally, LTCS with none-to-low BF reported better HRQOL at baseline and at follow-up than LTCS with higher BF. Longitudinally, no difference was found between none-to-low and moderate-to-high BF on the HRQOL change from baseline to follow-up. HRQOL differences between the PTG groups were not statistically significant cross-sectionally and longitudinally, except those participants with moderate-to-high PTG reported higher role functioning and global health status/QOL. CONCLUSIONS: Cross-sectionally, BF was significantly negatively related to subscales of HRQOL, while PTG was positively correlated to role functioning and global health status/QOL. The results add further evidence that BF and PTG are two different positive psychological concepts.

(1) Background: The health-related quality of life (HRQOL) of colorectal cancer (CRC) survivors >10 years post-diagnosis is understudied. We aimed to compare the HRQOL of CRC survivors 14-24 years post-diagnosis to that of age- and sex-matched non-cancer controls, stratified by demographic and clinical factors. (2) Methods: We used data from 506 long-term CRC survivors and 1489 controls recruited from German population-based multi-regional studies. HRQOL was assessed with the European Organization for Research and Treatment of Cancer Quality of Life Core-30 (EORTC QLQ-C30) questionnaire. We estimated differences in the HRQOL of CRC survivors and controls with multiple regression, adjusted for age at survey, sex, and education, where appropriate. (3) Results: CRC survivors reported poorer social functioning but better health status/QOL than controls. CRC survivors, in general, had higher levels of symptom burden, and in particular diarrhea and constipation, regardless of demographic or clinical factors. In stratified analyses, HRQOL differed by age, sex, cancer type, and having a permanent stoma. (4) Conclusions: Although CRC survivors may have a comparable health status/QOL to controls 14-24 years after diagnosis, they still live with persistent bowel dysfunction that can negatively impact aspects of functioning. Healthcare providers should provide timely and adapted follow-up care to ameliorate potential long-term suffering.

BACKGROUND: Little is known about how changes in a constellation of lifestyle factors affect health-related quality of life (HRQoL) in colorectal cancer (CRC) survivors. Our study aimed to investigate the association between changes in healthy lifestyle and HRQoL over time in survivors of stage I-IV CRC. METHODS: We included 2,283 long-term (≥5 years postdiagnosis) survivors. A healthy lifestyle score (HLS) comprising smoking, alcohol consumption, diet, physical activity, and body fatness was derived at diagnosis and 5-year follow-up (5YFU) and categorized as low, moderate, or high. We assessed HRQoL with the EORTC Quality of Life Questionnaire-Core 30 at 5YFU and 10-year follow-up. We used multivariable linear regression and linear mixed models to explore associations between changes in HLS and HRQoL over follow-up. RESULTS: A low baseline HLS was associated with poorer functioning and global health/QoL and a higher symptom burden at 5YFU compared with a high baseline HLS. An improved HLS from baseline to 5YFU was associated with better functioning, higher global health/QoL, and fewer symptoms at 5YFU than a maintained-high HLS. In longitudinal analyses, improved HLS was associated with better functioning at follow-up. Survivors with a maintained-high or an improved HLS reported generally less fatigue, pain, and dyspnea at follow-ups compared with survivors with a maintained-low or decreased HLS. CONCLUSIONS: Change toward a healthier lifestyle since diagnosis was associated with better HRQoL in long-term CRC survivors. Our results support the importance of maintaining and/or promoting a healthier lifestyle among CRC survivors postdiagnosis.

PURPOSE: It is important to monitor disease-specific health-related quality of life (HRQoL) in breast cancer (BC) survivors to identify potential unmet supportive care needs. However, previous studies were characterized by small samples of mostly short-term survivors and were limited to certain age ranges, stages and/or treatments. METHODS: We used data from 3045 long-term BC survivors (5-15 years post-diagnosis) recruited in a German multi-regional population-based study. We assessed disease-specific HRQoL with the EORTC QLQ-BR23, scoring from 0 to 100. Differences in functioning and symptoms according to age at survey, self-reported treatments, stage, and disease status (disease-free vs. active disease) were assessed with multiple regression. Active disease was defined as any self-report of recurrence, metastasis or second primary cancer after the index cancer. RESULTS: Older BC survivors reported a higher body image and a better future perspective, but lower sexual functioning. Survivors aged 30-49 years who had breast-conserving therapy or mastectomy with breast reconstruction reported a better body image compared to those who had mastectomy only. We also found differences in symptoms according to treatments in some age groups. Stage at diagnosis was not associated with HRQoL overall and in most age subgroups. Disease-free BC survivors aged 30-79 years reported a better future perspective and less systemic therapy side effects than those with active disease. CONCLUSION: Several treatment-associated symptoms and functioning detriments were found 5-15 years after diagnosis. The results emphasize the need of a comprehensive, individualized survivorship care, recognizing differential needs of long-term BC survivors according to age, treatment modalities, and disease status.

Background: Diabetes increases the risk of certain types of cancer. However, the literature regarding the incidence of diabetes after cancer diagnosis is inconsistent. We aimed to assess whether there was a higher incidence of diabetes among cancer patients by performing a systematic review and meta-analysis of results from cohort studies. Methods: A systematic electronic literature search was carried out from cohort studies regarding the incidence of diabetes in cancer patients, using the databases PubMed (MEDLINE), Embase, Web of Science, and the Cochrane Library. Random-effects meta-analyses were conducted to pool the estimates. Results: A total of 34 articles involving 360,971 cancer patients and 1,819,451 cancer-free controls were included in the meta-analysis. An increased pooled relative risk (RR) of 1.42 (95% confidence interval (CI): 1.30−1.54, I2 = 95, τ2 = 0.0551, p < 0.01) for diabetes in cancer patients was found compared with the cancer-free population. The highest relative risk was observed in the first year after cancer diagnosis (RR = 2.06; 95% CI 1.63−2.60). Conclusions: New-onset diabetes is positively associated with cancer, but this association varies according to cancer type. More prospective studies with large sample sizes and longer follow-up times are advocated to further examine the association and the underlying mechanisms.
RESUMEN
PURPOSE: Limited research suggests that cancer survivors have problems with insurance. Our study aimed to gain insight into the proportion of very long-term (14-24 years post-diagnosis) survivors of breast, colorectal, and prostate cancers who had problems with health (HI) and life (LI) insurance. METHODS: We used data from CAESAR (CAncEr Survivorship-A multi-Regional population-based study). Participants completed questions on change in insurance providers since cancer diagnosis, problems with requesting (additional) HI or LI, and how potential problems were resolved. We conducted logistic regression to determine factors associated with change in statutory HI. RESULTS: Of the 2714 respondents, 174 (6%) reported having changed HI providers. Most switched between different statutory HI providers (86%), 9% from statutory to private, and 5% from private to statutory. Respondents who changed statutory HI providers were more likely to be prostate cancer survivors (OR 2.79, 95% CI 1.01-7.68) while being ≥ 65 years at time of diagnosis (OR 0.58, 95% CI 0.35-0.96) and having ≥ 2 comorbid conditions (OR 0.61, 95% CI 0.40-0.92) were associated with reduced odds for change. Problems in changing HI were minimal and were resolved with additional contribution. Of the 310 respondents who tried to get LI, 25 respondents reported having difficulties, of whom the majority had their request rejected. CONCLUSION: Most cancer survivors did not change their HI nor tried to buy LI after cancer diagnosis. Problems with changing statutory HI were generally resolved with additional contribution while the main problem encountered when buying LI was rejection of request.

BACKGROUND: Being obese and having a sedentary lifestyle is associated with impaired health-related quality of life (HRQoL) among cancer survivors. The aim of the present study is to investigate the combined influence of body mass index (BMI) and physical activity on HRQoL in lymphoma survivors. METHODS: Lymphoma survivors diagnosed between 1999 and 2012 were invited to complete questionnaires about body height and weight, physical activity and HRQoL using the EORTC QLQ-C30. Multivariable analyses were conducted to evaluate the association of BMI and physical activity on HRQoL. RESULTS: 1.339 lymphoma survivors responded (response rate of 72%) of whom 43% had a healthy weight, 41% were overweight and 14% were obese. They spent on average 10 h, on moderate to vigorous physical activity (MVPA) per week. Multivariable linear regression analysis shows that relatively high active survivors reported higher HRQoL scores and less fatigue compared to relatively low active lymphoma survivors, regardless of BMI. CONCLUSION: MVPA was associated with higher HRQoL in lymphoma survivors regardless of BMI. Further studies, are needed to investigate effects of healthy lifestyle changes to improve HRQoL in lymphoma survivors. Research in understanding association of lifestyle factors may guide future support for lymphoma cancer survivors.

BACKGROUND: Colorectal cancer (CRC) survivors generally have a higher healthcare utilization (HCU) than the general population due to cancer burden. However, it is unclear which factors are associated with this increased uptake. Our study aimed to (1) compare CRC-related and non-CRC visits to general practitioners (GPs) and medical specialists (MSs) by comorbidities, and (2) assess whether HCU differs by demographic, clinical, and psychological factors. METHODS: We used data from a German population-based cohort of 1,718 survivors of stage I-III CRC diagnosed in 2003 through 2010 who provided information on HCU at 5-year follow-up. Multivariable linear regression was used to calculate least-square means of CRC-related and non-CRC HCU according to the Charlson comorbidity index and comorbidity cluster, adjusting for relevant demographic, clinical, and psychological characteristics. RESULTS: A higher comorbidity level was associated with more CRC-related MS visits and non-CRC GP visits. In addition to being strongly associated with non-CRC GP visits, comorbidity clusters were associated with CRC-related GP and MS visits, but their association varied by specific cardiometabolic comorbidities. HCU was less dependent on prognostic factors for CRC, such as age and tumor stage, but was strongly associated with disease recurrence, depression, and emotional functioning. CONCLUSIONS: Comorbidities, rather than age or tumor stage, were related to HCU, suggesting that CRC survivors use healthcare mainly for reasons other than cancer 5 years postdiagnosis. Improved communication between primary and tertiary healthcare providers could enhance the medical care of cancer survivors with complex health needs and thereby also reduce healthcare costs.

(1) To evaluate the prevalence of severe and chronic fatigue in subjects with and without chronic disease; (2) to assess to which extent multi-morbidity contributes to severe and chronic fatigue; and (3) to identify predisposing and associated factors for severe and chronic fatigue and whether these are disease-specific, trans-diagnostic, or generic. The Dutch Lifelines cohort was used, including 78,363 subjects with (n = 31,039, 53 ± 12 years, 33% male) and without (n = 47,324, 48 ± 12 years, 46% male) ≥ 1 of 23 chronic diseases. Fatigue was assessed with the Checklist Individual Strength-Fatigue. Compared to participants without a chronic disease, a higher proportion of participants with ≥ 1 chronic disease were severely (23% versus 15%, p < 0.001) and chronically (17% versus 10%, p < 0.001) fatigued. The odds of having severe fatigue (OR [95% CI]) increased from 1.6 [1.5-1.7] with one chronic disease to 5.5 [4.5-6.7] with four chronic diseases; for chronic fatigue from 1.5 [1.5-1.6] to 4.9 [3.9-6.1]. Multiple trans-diagnostic predisposing and associated factors of fatigue were found, explaining 26% of variance in fatigue in chronic disease. Severe and chronic fatigue are highly prevalent in chronic diseases. Multi-morbidity increases the odds of having severe and chronic fatigue. Several trans-diagnostic factors were associated with fatigue, providing a rationale for a trans-diagnostic approach.

BACKGROUND: The objective of this study was to ascertain long-term cancer survivors' (LTCS') appraisal of medical care and how these perceptions may influence their health and well-being, including benefit finding (BF) and posttraumatic growth (PTG). METHODS: In total, 6952 LTCS from a multiregional population-based study in Germany completed the Benefit Finding Scale, the Posttraumatic Growth Inventory, the Questionnaire on Stress in Cancer, and self-designed questions on cognitive appraisal of medical care. The authors explored the mediating role of distress between medical care appraisal and BF and PTG and the possible moderation of time since diagnosis in this relationship. RESULTS: LTCS' medical care appraisals ("no unresolved/untreated symptoms," "satisfaction with cancer care," and "satisfaction with care for other diseases") were positively associated with BF. PTG was positively associated with "no unresolved/untreated symptoms" and negatively associated with "satisfaction with care for other diseases." Cancer distress partially mediated the associations between appraisals of medical care and BF, between "no unresolved/untreated symptoms" and PTG and between "satisfaction with care for other diseases" and PTG; whereas it totally mediated the association between "satisfaction with cancer care" and PTG. Time was a significant moderator in the model; the negative indirect effect of cognitive appraisal on BF and PTG through cancer distress weakened with longer time since diagnosis. CONCLUSIONS: Cancer survivors' medical care appraisal is associated with their perceptions of BF and PTG through distress. Therefore, distress screening could be part of the regular workup to identify distressed cancer survivors who are not satisfied with medical care; these survivors may benefit from interventions to reduce distress and increase BF and PTG.

BACKGROUND: Cancer studies reported mixed results on benefit finding (BF) and posttraumatic growth (PTG) prevalence and few were focused on long-term survivors. METHODS: BF and PTG were assessed in a multi-regional population-based study in Germany with 6952 breast, colorectal and prostate cancer survivors, using the Benefit Finding Scale and Posttraumatic Growth Inventory. We calculated the age-adjusted prevalence, stratified by demographical and clinical characteristics. RESULTS: Overall, 66.0% of cancer survivors indicated moderate-to-high BF, and 20.5% moderate-to-high PTG. Age-adjusted prevalence of BF and PTG differed according to cancer type (breast > colorectal > prostate) and sex (female > male). BF and PTG prevalence were higher in younger than in older respondents; the age-adjusted prevalence was higher in respondents who survived more years after diagnosis. The strength and direction of associations of age-adjusted prevalence with cancer stage, disease recurrence, and time since diagnosis varied according to cancer type and sex. CONCLUSIONS: A substantial proportion of long-term cancer survivors reported moderate-to-high BF and PTG. However, the prevalence was lower in older and male cancer survivors, and during the earlier years after cancer diagnosis. Further longitudinal studies on PTG and BF in cancer survivors are warranted to address heterogeneity in survivors' experience after cancer diagnosis.

(1) Background: Little is known about the health-related quality of life (HRQoL) in very long-term cancer survivors (VLTCS) 10 and more years post-diagnosis. The objective was to compare cancer survivors' HRQoL 14-24 years post-diagnosis with that of same-aged non-cancer controls, stratified by age, sex, and disease status (disease-free vs. stage IV, recurrence, metastasis, or second cancer). (2) Methods: We recruited 2704 very long-term survivors of breast, colorectal and prostate cancer, and 1765 controls in German multi-regional population-based studies. The HRQoL was assessed by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). Differences in the HRQoL were estimated with multiple regression, controlling for age, sex (where appropriate), and education. (3) Results: The overall global health status/quality of life of VLTCS more than a decade after diagnosis was slightly higher than that of population controls of the same age, but more symptoms and lower functioning were reported. Differences were small but statistically significant. Results differed by age, sex, and disease status. (4) Conclusions: The findings point out the need for a comprehensive survivorship care program in order to monitor and treat potential late and long-term effects after the diagnosis and treatment of cancer. Survivorship care should be risk-adapted to survivors' needs according to sociodemographic and clinical factors.
RESUMEN
BACKGROUND: Fatigue is a distressing symptom in patients with COPD. Little is known about the factors that contribute to fatigue in COPD. This review summarises existing knowledge on the prevalence of fatigue, factors related to fatigue and the instruments most commonly used to assess fatigue in COPD. METHODS: Pubmed, PsycINFO, EMBASE, Cochrane and CINAHL databases were searched for studies from inception up to 7 January 2020 using the medical subject headings "COPD" and "Fatigue". Studies were reviewed in accordance with PRISMA guidelines. RESULTS: 196 studies were evaluated. The prevalence of fatigue ranged from 17-95%. Age (r=-0.23 to r=0.27), sex (r=0.11), marital status (r=-0.096), dyspnoea (r=0.13 to r=0.78), forced expiatory volume in 1â s % predicted (r=-0.55 to r=-0.076), number of exacerbations (r=0.27 to r=0.38), number of comorbidities (r=0.10), number of medications (r=0.35), anxiety (r=0.36 to r=0.61), depression (r=0.41 to r=0.66), muscle strength (r=-0.78 to r=-0.45), functional capacity (r=-0.77 to r=-0.14) and quality of life (r=0.48 to r=0.77) showed significant associations with fatigue. CONCLUSIONS: Fatigue is a prevalent symptom in patients with COPD. Multiple physical and psychological factors seem to be associated with fatigue. Future studies are needed to evaluate these underlying factors in integral analyses in samples of patients with COPD.

PURPOSE: Aside from urological and sexual problems, long-term (≥5 years after initial diagnosis) prostate cancer (PC) survivors might suffer from pain, fatigue, and depression. These concurrent symptoms can form a cluster. In this study, we aimed to investigate classes of this symptom cluster in long-term PC survivors, to classify PC survivors accordingly, and to explore associations between classes of this cluster and health-related quality of life (HRQoL). METHODS: Six hundred fifty-three stage T1-T3N0M0 survivors were identified from the Prostate Cancer Survivorship in Switzerland (PROCAS) study. Fatigue was assessed with the EORTC QLQ-FA12, depressive symptoms with the MHI-5, and pain with the EORTC QLQ-C30 questionnaire. Latent class analysis was used to derive cluster classes. Factors associated with the derived classes were determined using multinomial logistic regression analysis. RESULTS: Three classes were identified: class 1 (61.4%) - "low pain, low physical and emotional fatigue, moderate depressive symptoms"; class 2 (15.1%) - "low physical fatigue and pain, moderate emotional fatigue, high depressive symptoms"; class 3 (23.5%) - high scores for all symptoms. Survivors in classes 2 and 3 were more likely to be physically inactive, report a history of depression or some other specific comorbidity, be treated with radiation therapy, and have worse HRQoL outcomes compared to class 1. CONCLUSION: Three distinct classes of the pain, fatigue, and depression cluster were identified, which are associated with treatment, comorbidities, lifestyle factors, and HRQoL outcomes. Improving classification of PC survivors according to severity of multiple symptoms could assist in developing interventions tailored to survivors' needs.

BACKGROUND: Depression is more prevalent in breast cancer (BC) survivors than in the general population. However, little is known about depression in long-term survivors. Study objectives were: (1) to compare the age-specific prevalence of depressive symptoms (a) in BC survivors vs female population controls, (b) in disease-free BC survivors vs BC survivors with self-reported recurrence vs controls, and (2) to explore determinants of depression in BC survivors. METHODS: About 3010 BC survivors (stage I-III, 5-16 years post-diagnosis), and 1005 population controls were recruited in German multi-regional population-based studies. Depression was assessed by the Geriatric Depression Scale-15. Prevalence of mild/severe and severe depression only were estimated via logistic regression, controlling for age and education. Multinomial logistic regression was used to explore determinants of mild and severe depression. RESULTS: Compared with population controls, BC survivors were more likely to report mild/severe depression (30.4% vs 23.8%, p = .0003), adjusted for age and education. At all age groups <80 years, prevalence of both mild/severe and severe depression only was significantly higher in BC survivors, while BC survivors ≥80 years reported severe depression less frequently than controls. BC survivors with recurrence reported significantly higher prevalence of mild/severe depression than disease-free survivors and controls, but prevalence in disease-free survivors and controls was comparable. Age, income, living independently, recurrence, and BMI were significant determinants of mild depression in BC survivors. Age, education, employment, income, recurrence, and BMI were significant determinants of severe depression. CONCLUSIONS: Long-term BC survivors <80 years report significantly higher prevalence of depressive symptoms than controls, which might be explained by recurrence and individual factors. The findings suggest that depression in BC survivors is common, and even more after BC recurrence. Clinicians should routinize screening and normalize referral to psychological care.
