Lymphoma Survivors Research Articles

Sexual dysfunction in lymphoma survivors: a scoping review.

Lymphoma and cancer-related treatment can cause many complications, including sexual dysfunction, a common symptom experienced by lymphoma survivors during the disease trajectory and survivorship. A scoping review was performed to determine the current state of knowledge about sexual dysfunction in lymphoma survivors and identify knowledge gaps and implications for future research. PubMed, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO were searched to identify all primary peer-reviewed research articles published in the English language that were pertinent to sexual dysfunction in lymphoma survivors. The framework of Arksey and O'Malley and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews Checklist were used to assess and synthesize the available evidence on sexual dysfunction in lymphoma survivors. This review provided supportive evidence that sexual function in lymphoma survivors is a major ongoing area of concern. Thirty eligible articles published from 1979 to 2023 were appraised in this review. Most of the studies (73.33%) used a cross-sectional design. Using the Methodological Index for Non-Randomized Studies, more than half of the publications (53.33%) achieved a C quality ranking. The reviewed studies revealed that sexual dysfunction was a prevalent symptom experienced by lymphoma survivors, with predictors such as age, gender, sex hormones, stage of disease, and types of cancer treatment. Healthcare providers need to consistently perform routine assessment of sexual function and provide adequate treatment options. The reviewed studies document the problem of sexual dysfunction and offer potential areas of improvement for clinical practice. However, in the majority of the studies, longitudinal data were not obtained which could provide valuable insights on sexual functioning in lymphoma survivors. Despite many years of research on sexual function in lymphoma survivors, substantial gaps in knowledge regarding sexual issues in this population remain. Healthcare providers should routinely assess sexual function of survivors and provide treatment options. Psychosexual interventions should be tailored for the needs of cancer survivors. Sexual function education is essential for all oncologists and should be included in the care pathway from diagnosis until survivorship.

Cancer survivor preferences on the timing and content of interventions to mitigate financial toxicity associated with cancer treatment.

Despite growing research on financial toxicity among cancer survivors, large gaps remain in understanding how to intervene to minimize financial toxicity. Uptake and efficacy of interventions mitigating cancer financial toxicity, though promising, remain limited and inconsistent. To date, survivor preferences for financial toxicity interventions are underexplored. This study aimed to evaluate survivor preferences for timing and content of a survivor-facing intervention to address financial toxicity. Adult survivors (N = 105) of colorectal cancer (N = 55) or Non-Hodgkin Lymphoma (N = 50) from three tertiary care centers self-reported demographic and clinical characteristics, comorbidities, mental health, financial impact of cancer (Comprehensive Score for Financial Toxicity scale), and preferences for intervention timing and content. Chi-square tests examined associations between intervention timing and content preferences with financial toxicity score. ANOVAs and correlation analyses described associations between the number of intervention components survivors endorsed and survivors' characteristics. Regarding intervention timing, 79% of survivors favored intervention before treatment. The most frequently endorsed content was understanding out-of-pocket costs and insurance (48.6%) and applying for aid (39%). Survivors experiencing higher financial toxicity reported greater interest in all intervention components. Survivors with colorectal cancer (p = .018), < 65years (p = .019), higher financial toxicity (p < .001), greater life-altering (p < .001) and care-altering (p = .014) coping behaviors, and poorer mental health (p = .008) endorsed more intervention components. Actionable insights to improve financial toxicity interventions may be to offer assistance earlier than currently provided(i.e. before treatment) and to include certain topics currently rarely offered (e.g., stress management, budget development support) in line with survivors' preferences.

Sexual dysfunction among long-term survivors of Hodgkin lymphoma.

Survival rates from childhood cancer continue to increase, with an ongoing interest in long-term survivorship. Although infertility and gonadal failure are well recognized in Hodgkin lymphoma (HL) survivors, sexual dysfunction is less studied. The objective of this study was to compare the prevalence of sexual dysfunction in HL survivors with that in matched community controls. Long-term survivors of HL (n=186; female, 51.61%; mean age at diagnosis. 14.41 years [range, 3.01-22.60 years]; current mean±standard deviation age, 36.73±7.93 years) and matched community controls (n=182; female, 50.55%; mean±standard deviation age, 36.41±9.02 years) completed a comprehensive, in-person clinical assessment, laboratory battery, and the International Index of Erectile Function or the Female Sexual Function Index questionnaire. Male survivors had increased levels of erectile dysfunction (18.89% vs. 6.67%; p=.0239) but indicated no difference in sexual desire. Female survivors had a higher prevalence of sexual dysfunction compared with female controls (46.88% vs. 15.22%; p<.0001) and an increased prevalence of moderate-to-severe loss of sexual desire (38.04% vs. 23.26%; p=.0361). Female survivors with sexual dysfunction indicated increased levels of anxiety (p=.0184), depression (p=.0153), and worse physical and mental health (p=.0141 and p=.0419, respectively). Male survivors with erectile dysfunction had higher rates of anxiety and impaired physical health (p=.0147 and p=.0266, respectively). Sexual dysfunction was prevalent in this childhood and adolescent Hodgkin lymphoma survivor cohort and was associated with effects on quality of life. Health care providers must recognize the need for screening and intervention in this group to hopefully contribute to improved overall quality of life.

Concordance between late effects reported by physicians and patients in a cohort of long-term Hodgkin lymphoma survivors: an analysis of data from nine consecutive EORTC-LYSA trials.

Studies looking into the concordance between late effects reported by physicians vs. those reported by Hodgkin lymphoma (HL) survivors are missing. A Life Situation Questionnaire focusing on late effects collected data from 1230 HL survivors (median follow-up 14.3years). Twenty-six disease- and treatment-related late effects from various organ systems were matched with physician-recorded data. The concordance between physicians and survivors was systematically evaluated using percentage agreement and kappa statistics. Potential non-responder biases and associations with patient and disease characteristics were also investigated. Agreement levels (indicated by kappa statistics) varied from none to moderate agreement, with the highest Kappa values observed for myocardial infarction (kappa = 0.55, 95% CI 0.43-0.66) and pulmonary embolism (kappa = 0.55, 95% CI 0.35-0.75). HL survivors consistently reported a higher prevalence of late effects compared with physicians. Notably, the prevalence of subjective symptoms such as persistent fatigue and xerostomia was repeatedly underreported by physicians. A trend towards higher concordance was observed in survivors with higher clinical stage, higher education level, and treatment initiated at younger ages. Additionally, findings indicated that survivors who did not respond to the questionnaire experienced fewer late effects compared to those who did respond. Substantial discrepancies were noted in the reported prevalence of late effects between survivors and physicians, especially for outcomes which are not easily quantified. It is therefore essential to integrate outcomes reported by both physicians and survivors to achieve a comprehensive assessment of the long-term consequences of HL treatment.

Comparing the measurement properties of the EQ-5D-5L, SF-6Dv2, QLU-C10D and FACT-8D among survivors of classical Hodgkin's lymphoma.

This study aimed to evaluate the measurement properties of EQ-5D-5L, SF-6Dv2, QLU-C10D, and FACT-8D in survivors of Classical Hodgkin's Lymphoma (CHL). A cross-sectional, web-based survey was conducted from May to August 2022 to collect data. Chinese value sets were used to estimate the utility scores for EQ-5D-5L, SF-6Dv2, and QLU-C10D, while the Australian value set was used for FACT-8D. The measurement properties assessed included ceiling and floor effects, convergent validity (assessing associations between similar dimensions/utility scores using Spearman's rank correlation and intraclass correlation coefficient), and known-group validity (measures could differentiate health-related quality of life (HRQoL) between risk groups). A total of 534 CHL survivors participated in the survey and completed the questionnaire. All dimensions of EQ-5D-5L, SF-6D (except for vitality), QLU-C10D, and FACT-8D showed ceiling effects, ranging from 18 to 91.6%. The EQ-5D-5L demonstrated the higher ceiling effects compared to other measures, with 33% of patients reporting full health on this scale. All 30 pairs of associations between similar dimensions from the four measures were statistically significant, with correlation coefficients ranging from 0.29 to 0.77. Regarding utility scores, the EQ-5D-5L utility score showed a stronger correlation with SF-6Dv2 than with the other two measures. Statistically significant correlations of utility scores between the four measures were observed. EQ-5D-5L can significantly differentiate HRQoL among all known-groups, while SF-6Dv2, QLU-C10D, and FACT-8D showed a less strong discriminant ability. EQ-5D-5L outperformed SF-6Dv2 in terms of agreement with cancer-specific PRMs and discriminant ability. However, SF-6Dv2 showed stronger associations with similar dimensions of QLU-C10D and FACT-8D, indicating high convergent validity. The generic PBMs are sensitive enough to measure HRQoL in survivors of CHL.

Reducing Learning and Psychosocial Disparities in Latino Children with Cancer: A Randomized Intervention Trial.

We developed a high-intensity parenting intervention (HIP) to help parents support the academic success of childhood cancer survivors (CCSs), who often face post-treatment challenges affecting their school-related functioning. This randomized controlled trial (NCT03178617) evaluated HIP's efficacy compared to lower-intensity, single-session, treatment-as-usual services (LIP) in Latino families. Primary outcomes were parenting efficacy and CCSs' school functioning; secondary outcomes included parenting knowledge and measures of CCSs' academic performance, attention, and functioning outside of school. 106 Latino survivors of childhood leukemia and lymphoblastic lymphoma (aged 6-12 years) and their parents were randomly assigned to HIP (n = 54) or LIP (n = 52). Linear mixed-effects models evaluated group differences across baseline, 6-month (T2), and 12-month (T3) assessments. Parenting efficacy and knowledge improved significantly in the HIP arm, resulting in higher scores vs LIP at T2 and T3 (P ≤ .01). No significant between-group differences were found in child school functioning; however, HIP children showed significantly better social functioning and performance on one measure of attention (CPT-3 commissions) at T3 (P < .05). While HIP adherence challenges were observed, with only 33 (61%) completing the intervention, exploratory analyses suggest that benefits were most evident among those who fully engaged. Satisfaction and perceived benefit were greater for HIP vs LIP at both time points (P < .05). Our results suggest the potential value of parent-directed behavioral interventions like HIP for CCSs and their families. Further studies are needed to address participation barriers and enhance engagement to maximize and sustain benefits.

Quality of life and late therapy effects in pediatric non-Hodgkin lymphoma survivors: Insights from a single-institution study.

The survival outcomes of pediatric patients with mature B-non-Hodgkin lymphoma (NHL) have improved due to advances in treatment. We aimed to assess the frequency and severity of late effects and their impact on quality of life among pediatric NHL survivors. This retrospective study included patients diagnosed with mature B-NHL at Children's Cancer Hospital of Egypt (CCHE) 57357 from January 2012 through December 2015. Patients received treatment according to the modified LMB 96 protocol. The minimum follow-up period was 5years. Assessments for toxicity and quality of life were conducted at regular intervals during and after treatment. Patients were assessed for toxicity including pulmonary dysfunction, cardiac dysfunction, lipid profile abnormalities, endocrine dysfunction (thyroid function, vitamin D levels, growth curves), and cognitive function (intelligence quotient [IQ] level using Stanford-Binet Intelligence Scales-5th Edition, and quality of life (QoL) assessment (PedsQoL). A total of 273 patients were eligible, and 206 were evaluable. Median age was 5.45 (range: 2.4-18), with a male-to-female ratio 4:1. Pulmonary function abnormalities were detected in 119/203 (58.6%); most had mild dysfunction (72/119, 60.5%), while 17% had severe dysfunction. Cardiac toxicity occurred in 10% of the patients (n=20). IQ testing showed that 52 patients had a low average IQ score, while 151 patients had either average or above average scores. The total mean QoL score was 99±0.058 classified as "satisfactory." However, significant impairment of the physical domain of quality of life was observed among group C patients compared to A/B (p=.033), older age at diagnosis (p=.042), and those with pulmonary dysfunction (p<.001). Total score of quality of life was significantly impaired among patients with pulmonary dysfunction (p=.009), likewise older age at diagnosis (p=.017) and those with low average IQ scores (p=.033). Childhood mature B-NHL survivors are at significant risk for late effects; pulmonary dysfunction and low average IQ that can subsequently impact QoL.

Adherence to guideline-recommended cardiac screening in Medicaid-enrolled survivors of childhood cancer: A report from the Childhood Cancer Survivor Study (CCSS).

56 Background: Childhood cancer survivors face increased risks of heart failure and myocardial dysfunction associated with cancer treatment exposure. Children’s Oncology Group (COG) guidelines recommend periodic cardiac screening for survivors exposed to anthracycline or radiation. However, the extent of adherence to cardiac screening among Medicaid-enrolled survivors—a group typically characterized by socioeconomic disadvantages—remains unclear. Additionally, as Medicaid expansion under the Affordable Care Act has occurred in most, but not all states, cardiac screening adherence may vary based on survivors' state of residence. Methods: Data from the CCSS were linked to administrative Medicaid insurance claims from 2015 to 2019. We included at-risk survivors (i.e., received radiation to chest or heart, total body irradiation, and/or anthracyclines), aged 18-64 years, continuously covered by Medicaid during 2015-2019, and without a history of grade 3-4 cardiovascular conditions by 2019 to ensure the identified cardiac tests were for screening purposes. Our primary outcome assessed adherence to COG guidelines (V4.0) based on age- and therapy dose-specific frequency of cardiac testing (i.e., echocardiogram, multigated acquisition scan, or magnetic resonance imaging) during the study period. Multivariable logistic models assessed sociodemographic, clinical, and policy-related factors associated with adherence, with adjusted probability differences (i.e., marginal effects [MEs]) reported. Results: We identified 1,062 survivors at risk of cardiovascular conditions, with 57.0% female, 52.8% young adults (ages 18-39 years), and 72.8% non-Hispanic White. During 2015-2019, 285 (26.8%) survivors received any cardiac test, and 102 (9.6%) adhered to COG guideline-based frequency of cardiac testing. In multivariable models, survivors residing in states that expanded Medicaid in 2014 and later has 4.3 percentage points (ppts, 95% CI=0.58.1, p =0.025) and 6.1 ppts (95% CI=0.611.6, p =0.031) increased likelihood of adhering to guideline-based frequency of cardiac testing respectively compared to states that did not. Compared to leukemia survivors, the likelihood of adhering to guideline-based frequency of cardiac testing was higher in survivors of central nervous system tumors (ME=7.6 ppt, 95% CI=2.712.6, p =0.002), Hodgkin lymphoma (ME=10.7 ppt, 95% CI=1.320.1, p =0.026), and non-Hodgkin lymphoma (ME=9.4, 95% CI=1.017.8, p =0.028). Conclusions: Adherence to risk-based cardiac testing is low among Medicaid-enrolled survivors of childhood cancer, and associated with residence in a Medicaid expansion state and cancer type. Policy reforms toward improving affordable, continuous health insurance coverage are important means to increase adherence to guideline-based cardiac tests among survivors.

Development and validation of machine learning models for predicting cancer-related fatigue in lymphoma survivors

BackgroundNew cases of lymphoma are rising, and the symptom burden, like cancer-related fatigue (CRF), severely impacts the quality of life of lymphoma survivors. However, clinical diagnosis and treatment of CRF are inadequate and require enhancement. ObjectiveThe main objective of this study is to construct machine learning-based CRF prediction models for lymphoma survivors to help healthcare professionals accurately identify the CRF population and better personalize treatment and care for patients. MethodsA cross-sectional study in China recruited lymphoma patients from June 2023 to March 2024, dividing them into two datasets for model construction and external validation. Six machine learning algorithms were used in this study: Logistic Regression (LR), Random Forest, Single Hidden Layer Neural Network, Support Vector Machine, eXtreme Gradient Boosting, and Light Gradient Boosting Machine (LightGBM). Performance metrics like the area under the receiver operating characteristic (AUROC) and calibration curves were compared. The clinical applicability was assessed by decision curve, and Shapley additive explanations was employed to explain variable significance. ResultsCRF incidence was 40.7 % (dataset I) and 44.8 % (dataset II). LightGBM showed strong performance in training and internal validation. LR excelled in external validation with the highest AUROC and best calibration. Pain, total protein, physical function, and sleep disturbance were important predictors of CRF. ConclusionThe study presents a machine learning-based CRF prediction model for lymphoma patients, offering dynamic, data-driven assessments that could enhance the development of automated CRF screening tools for personalized management in clinical practice.

Providing Survivorship Care for a Young Adult With a History of Blood Cancer

Adolescents and young adults (AYAs) with a history of cancer are at an increased risk for late effects from their cancer treatment and have higher rates of long-term morbidity and mortality compared to their age-matched peers. As a result, this vulnerable population needs attentive follow-up care, end-organ surveillance, and secondary cancer screening; however, a history of cancer can often become buried on a problem list or not addressed at all. This case report illustrates an AYA survivor of classic Hodgkin lymphoma who relocates to a new city and establishes care with a new primary care provider (PCP). The PCP's awareness of a prior cancer diagnosis and the previous treatment regimen is a critical component in providing comprehensive care. In this case, the PCP's first step is to reach out and collaborate with oncology providers to gather an accurate treatment summary and then consult evidence-based guidelines to develop a plan of care. Based on the patient's previous treatment with chemotherapy adriamycin, bleomycin, vinblastine, and dacarbazine, the PCP orders recommended testing, reviews results, and provides subsequent counseling on health promotion and psychosocial wellness. This case illustrates strategies healthcare providers can use to provide coordinated, evidence-based care for AYA cancer survivors.

Survivorship preparedness and activation among survivors of lymphoma.

Taking an active role in managing post-treatment care has emerged as a key aspect of promoting a successful transition into survivorship and is associated with better patient outcomes. In this study, we focus on two key aspects of active self-management, activation and preparedness. Activation was defined as understanding one's role in the care process and having the knowledge, skill, and confidence to take on a role in managing self-care. Preparedness was defined as the extent to which individuals perceived they had sufficient information about what to expect after cancer treatments are completed. The study goal was to characterize survivorship preparedness and activation among lymphoma survivors within 5years of treatment completion in New Jersey and examine the association of sociodemographic, medical, care transition experiences, practical concerns, and psychosocial factors with activation and preparedness. One hundred and one Hodgkin lymphoma or non-Hodgkin lymphoma survivors who had completed treatment within 5years completed a survey of survivorship care experiences (response rate = 34.12%). Approximately 60% of survivors reported high activation, with similar percentages for higher preparedness. Less activated survivors were significantly (p < .05) younger, married, resided in a more deprived geographic area, and reported more fatigue and information needs. Less activated survivors reported recalling that their providers were significantly (p < .05) less likely to discuss long-term side effects, psychosocial needs, risk-reducing lifestyle recommendations, and how to manage other medical concerns. Fewer care transition practices were most strongly associated with lower preparedness. A significant proportion were not activated for survivorship, and both activation and preparedness were strongly associated with providers' survivorship transition practices. Implementing programs to foster more activation and preparedness for lymphoma survivorship care would benefit from education about recommended follow-up care and healthy lifestyle practices. Providers should routinely ask about their patients' confidence and preparedness for survivorship and provide referrals for appropriate care as needed.

Treatments affecting splenic function as a risk factor for valvular heart disease in Childhood Cancer Survivors: A DCCSS-LATER study.

Splenectomy might be a risk factor for valvular heart disease (VHD) in adult Hodgkin lymphoma survivors. As this risk is still unclear for childhood cancer survivors (CCS), the aim of this study is to evaluate the association between treatments affecting splenic function (splenectomy and radiotherapy involving the spleen) and VHD in CCS. CCS were enrolled from the DCCSS-LATER cohort, consisting of 6,165 five-year CCS diagnosed between 1963 and 2002. Symptomatic VHD, defined as symptoms combined with a diagnostic test indicating VHD, was assessed from questionnaires and validated using medical records. Differences in the cumulative incidence of VHD between CCS who received treatments affecting splenic function and CCS who did not were assessed using the Gray test. Risk factors were analyzed in a multivariable Cox proportional hazards model. The study population consisted of 5,286 CCS, with a median follow-up of 22 years (5-50 years), of whom 59 (1.1%) had a splenectomy and 489 (9.2%) radiotherapy involving the spleen. VHD was present in 21 CCS (0.4%). The cumulative incidence of VHD at the age of 40 years was significantly higher in CCS who received treatments affecting splenic function (2.7%, 95% confidence interval (CI) 0.4%-4.9%) compared with CCS without (0.4%, 95% CI 0.1%-0.7%) (Gray's test, p=0.003). Splenectomy was significantly associated with VHD in a multivariable analysis (hazard ratio 8.6, 95% CI 3.1-24.1). Splenectomy was associated with VHD. Future research is needed to determine if CCS who had a splenectomy as part of cancer treatment might benefit from screening for VHD.

Relationships, marriage, and partner abandonment among Hodgkin lymphoma survivors treated in nine EORTC-GELA Lymphoma Group trials

Distressed personality is associated with late adverse effects in long-term survivors of Hodgkin lymphoma.

There are few studies of personality traits in long-term Hodgkin lymphoma survivors (HLSs) treated according to contemporary stage-and risk-adapted approaches. The Distressed Personality (DP) Scale covers negative affectivity and social inhibition. We examined differences in self-reported late adverse effects (LAEs) between HLSs with and without DP and other explanatory variables. This cross-sectional questionnaire-based study included a population-based cohort of HLSs treated from 1997 to 2006, aged 8-49 years at diagnosis, and alive in 2016. Among 518 eligible HLSs, 303 responded (58%), and 294 completed the DP scale. DP was defined by scores above cut-off on both the negative affectivity and social inhibition subscales. LAEs studied were major depression, posttraumatic stress disorder, sleep problems, obesity, neuropathy, fatigue, memory problems, and general health. DP and 10 other explanatory variables were tested against LAEs as dependent variables in multivariable regression analyses. The mean age at survey was 45.9 years (standard deviation [SD] 4.6), mean follow-up time 16.7 years (SD 3.0), and 48% were females. Eighty-two HLSs had DP (28%, 95% confidence interval 23% - 33%). All LAEs except obesity were significantly more common/had higher mean score in HLSs with DP. In multivariable analyses, presence of DP was significantly associated with all LAEs except obesity. The presence of DP is common among HLSs. The presence of DP was associated with most self-report LAEs examined. Including assessment of personality traits in the survivorship care plans of HLSs should be considered. Prospective studies assessing the influence of pretreatment DP on LAEs are warranted.

Survivorship after Hodgkin lymphoma and the right to be forgotten.

The significantly improved survivorship in Hodgkin lymphoma is fraught with challenges, including persistent symptoms, secondary health complications, and socio-professional obstacles. This review highlights the need for comprehensive survivorship care plans that include detection of relapse, assessment of long-term side effects, screening for secondary cancers, psychological support, and assistance with socio-professional integration. Cardiovascular diseases, secondary malignancies and other associated risks remains an important problem related to the effective treatment of patients with Hodgkin lymphoma. Furthermore, fertility concerns and endocrine disorders remain prevalent issues posttreatment. An optimal evaluation of the risks before and after treatment is essential to reduce the impact of these side effects on quality of life. Addressing the socio-professional reintegration of survivors, the concept of the 'Right to be forgotten' emerges as a critical consideration. This principle seeks to eliminate discrimination against cancer survivors in accessing financial services and aims for legislative changes to ensure that past cancer diagnosis does not unfairly affect survivors' futures. Implementation of this 'Right to be forgotten' in the legislature, is currently underway in European countries. The focus of survivorship care has shifted towards the holistic management of these long-term outcomes. Quality of life for Hodgkin lymphoma survivors is affected by various treatment-related factors, with evidence suggesting that physical, psychological and socio-professional domains remain impacted years after treatment.

Survival trend and outcome prediction for pediatric Hodgkin and non-Hodgkin lymphomas based on machine learning

Pediatric Hodgkin and non-Hodgkin lymphomas differ from adult cases in biology and management, yet there is a lack of survival analysis tailored to pediatric lymphoma. We analyzed lymphoma data from 1975 to 2018, comparing survival trends between 7,871 pediatric and 226,211 adult patients, identified key risk factors for pediatric lymphoma survival, developed a predictive nomogram, and utilized machine learning to predict long-term lymphoma-specific mortality risk. Between 1975 and 2018, we observed substantial increases in 1-year (19.3%), 5-year (41.9%), and 10-year (48.8%) overall survival rates in pediatric patients with lymphoma. Prognostic factors such as age, sex, race, Ann Arbor stage, lymphoma subtypes, and radiotherapy were incorporated into the nomogram. The nomogram exhibited excellent predictive performance with area under the curve (AUC) values of 0.766, 0.724, and 0.703 for one-year, five-year, and ten-year survival, respectively, in the training cohort, and AUC values of 0.776, 0.712, and 0.696 in the validation cohort. Importantly, the nomogram outperformed the Ann Arbor staging system in survival prediction. Machine learning models achieved AUC values of approximately 0.75, surpassing the conventional method (AUC = ~ 0.70) in predicting the risk of lymphoma-specific death. We also observed that pediatric lymphoma survivors had a substantially reduced risk of lymphoma after ten years b,ut faced an increasing risk of non-lymphoma diseases. The study highlights substantial improvements in pediatric lymphoma survival, offers reliable predictive tools, and underscores the importance of long-term monitoring for non-lymphoma health issues in pediatric patients.

Accelerated aging among survivors of childhood leukemia and lymphoma: Estimates of early onset and excess morbidity from the COMPASS model.

10028 Background: Cohort studies have detected an increased risk of accelerated aging among survivors of childhood cancer but the timing and magnitude are not known. Methods: To predict the clinical course of diseases of aging— cancer and cardiovascular disease — among survivors of childhood leukemia and lymphoma compared to the general population, we developed the Cancer Outcomes Microsimulation: Pediatric and Adolescent SurvivorShip (COMPASS) model. The model simulates 8 severe, disabling or life-threatening chronic health conditions (CHCs), including 4 subsequent cancers (breast, colorectal, glial tumors, sarcomas) and 4 cardiovascular diseases (heart failure, myocardial infarction/coronary artery disease, valvular disease, stroke), and excess mortality risks among survivors diagnosed between 1970 and 1999 over the course of their lifetimes. Treatment-related risks varied by patient characteristics (sex, age at diagnosis, diagnosis) and treatment exposures (chemotherapy, radiation dose) and were based on data from the Childhood Cancer Survivor Study (CCSS). Age-related risks and competing mortality were based on national databases (SEER, NHLBI, CDC Wonder). We used model calibration to identify parameter sets that generated outcomes consistent with observed data. Model outcomes included cumulative CHC risk. For comparisons to the general population, age-, sex, and diagnosis year-matched individuals who faced only age-related risks were simulated. Results: Among survivors representative of CCSS participants, the model estimated that 45% of leukemia and 65% of lymphoma survivors will develop at least 1 of the 8 CHCs by age 65. Compared to the estimated 20% cumulative risk for the general population, this represented a two- to three-fold excess morbidity risk among survivors. The age at which 20% of survivors developed at least 1 CHC was 51 years for leukemia and 42 years for lymphoma, suggesting an early onset of 14 and 21 years compared to the general population. Outcomes varied by diagnosis and treatment era due to competing risk changes. Among leukemia survivors diagnosed in the 1990s vs. 1970s, cumulative late recurrence mortality by age 40 (11% to 1%) declined. This combined with a reduction in radiation exposure (79% to 24%) resulted in a greater proportion living into adulthood and developing CHCs by age 65 (38% to 48%). In contrast, among lymphoma survivors, the proportion projected to develop a CHC by age 65 remained stable during the same period (62% to 65%) as late recurrence mortality risk declined (8% to 1%), but almost half still received radiation (90% to 49%). Conclusions: Despite improvements in therapy, leukemia and lymphoma survivors are projected to experience CHC early onset and excess morbidity, underscoring the importance of prevention-focused survivorship care and continued efforts to develop more targeted therapies.

Aerobic exercise training combined with local strength exercise restores muscle blood flow and maximal aerobic capacity in long-term Hodgkin lymphoma survivors.

It is unclear whether muscle blood flow (MBF) is altered in long-term Hodgkin lymphoma (HL) survivors. We tested the hypothesis that 1) MBF response during mental stress (MS) is impaired in long-term HL survivors and 2) aerobic exercise training combined with local strength exercise (ET) restores MBF responses during MS in these survivors. Eighteen 5-year HL survivors and 10 aged-paired healthy subjects (HC) were studied. Twenty HL survivors were randomly divided into two groups: exercise-trained (HLT, n = 10) and untrained (HLUT, n = 10). Maximal aerobic capacity was evaluated by a cardiopulmonary exercise test and forearm blood flow (FBF) by venous occlusion plethysmography. MS was elicited by Stroop color and word test. ET was conducted for 4 mo, 3/wk for 60 min each session. The aerobic exercise intensity corresponded to anaerobic threshold up to 10% below the respiratory compensation point. The strength exercises consisted of two to three sets of chest press, pulley and squat exercises, 12-15 repetitions each exercise at 30-50% of the maximal voluntary contraction. Baseline was similar in HL survivors and HC, except peak oxygen consumption (peak V̇o2, P = 0.013) and FBF (P = 0.006) that were lower in the HL survivors. FBF responses during MS were lower in HL survivors (P < 0.001). ET increased peak V̇o2 (11.59 ± 3.07%, P = 0.002) and FBF at rest (33.74 ± 5.13%, P < 0.001) and during MS (24 ± 5.31%, P = 0.001). Further analysis showed correlation between the changes in peak V̇o2 and the changes in FBF during MS (r = 0.711, P = 0.001). In conclusion, long-term HL survivors have impaired MBF responses during MS. ET restores MBF responses during MS.NEW & NOTEWORTHY Long-term Hodgkin lymphoma (HL) survivors have impaired muscle blood flow responses during mental stress and decreased maximal aerobic capacity. Supervised aerobic exercise training combined with local strength exercises restores muscle blood flow responses during mental stress and maximal aerobic capacity in these survivors. These findings provide evidence of safety and effectiveness of exercise training in HL survivors. Moreover, they highlight the importance of exercise training in the treatment of this set of patients.
