Targeted long-read sequencing of the Ewing sarcoma 6p25.1 susceptibility locus identifies germline-somatic interactions with EWSR1-FLI1 binding.

Ewing sarcoma (EwS) is a rare bone and soft tissue malignancy driven by chromosomal translocations encoding chimeric transcription factors, such as EWSR1-FLI1, that bind GGAA motifs forming novel enhancers that alter nearby expression. We propose that germline microsatellite variation at the 6p25.1 EwS susceptibility locus could impact downstream gene expression and EwS biology. We performed targeted long-read sequencing of EwS blood DNA to characterize variation and genomic features important for EWSR1-FLI1 binding. We identified 50 microsatellite alleles at 6p25.1 and observed that EwS-affected individuals had longer alleles (>135 bp) with more GGAA repeats. The 6p25.1 GGAA microsatellite showed chromatin features of an EWSR1-FLI1 enhancer and regulated expression of RREB1, a transcription factor associated with RAS/MAPK signaling. RREB1 knockdown reduced proliferation and clonogenic potential and reduced expression of cell cycle and DNA replication genes. Our integrative analysis at 6p25.1 details increased binding of longer GGAA microsatellite alleles with acquired EWSR-FLI1 to promote Ewing sarcomagenesis by RREB1-mediated proliferation.

Factors influencing risk-based care of the childhood cancer survivor in the 21st century.

The population of adult survivors of childhood cancer continues to grow as survival rates improve. Although it is well established that these survivors experience various complications and comorbidities related to their malignancy and treatment, this risk is modified by many factors that are not directly linked to their cancer history. Research evaluating the influence of patient-specific demographic and genetic factors, premorbid and comorbid conditions, health behaviors, and aging has identified additional risk factors that influence cancer treatment-related toxicity and possible targets for intervention in this population. Furthermore, although current long-term follow-up guidelines comprehensively address specific therapy-related risks and provide screening recommendations, the risk profile of the population continues to evolve with ongoing modification of treatment strategies and the emergence of novel therapeutics. To address the multifactorial modifiers of cancer treatment-related health risk and evolving treatment approaches, a patient-centered and risk-adapted approach to care that often requires a multidisciplinary team approach, including medical and behavioral providers, is necessary for this population.

The burden of cardiovascular disease and risk for subsequent major adverse cardiovascular events in survivors of childhood cancer: a prospective, longitudinal analysis from the St Jude Lifetime Cohort Study.

BACKGROUND: The effect of the increasing lifetime burden of non-major cardiovascular conditions on risk for a subsequent major adverse cardiovascular event among survivors of childhood cancer has not been assessed. We aimed to characterise the prevalence of major adverse cardiovascular events and their association with the cumulative burden of non-major adverse cardiovascular events in childhood cancer survivors. METHODS: This is a longitudinal cohort study with participant data obtained from an ongoing cohort study at St Jude Children's Research Hospital: the St Jude Lifetime Cohort Study (SJLIFE). Prospective clinical follow-up was of 5-year survivors of childhood cancer who were diagnosed when aged younger than 25 years from 1962 to 2012. Age-frequency, sex-frequency, and race-frequency matched community-control participants completed a similar one-time clinical assessment. 22 cardiovascular events were graded using a St Jude Children's Research Hospital-modified version of the National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.03). Cumulative incidence and burden of the primary outcome of major adverse cardiovascular events (cardiomyopathy, myocardial infarction, stroke, and other cardiovascular-related mortality) were estimated. Rate ratios (RR) of the association of major adverse cardiovascular events with 22 non-major adverse cardiovascular events were estimated using multivariable piecewise-exponential regression adjusting for attained age, age at diagnosis, sex, race and ethnicity, treatment era, diagnosis of diabetes, and exposure to cardiotoxic cancer therapies. The St Jude Lifetime Cohort study is registered with ClinicalTrials.gov, NCT00760656, and is ongoing. FINDINGS: 9602 5-year survivors of childhood cancer, and 737 community controls were included in the longitudinal follow-up (from Sept 13, 2007, to Dec 17, 2021). The median follow-up was 20·3 years (IQR 12·0-31·4) from the date of primary cancer diagnosis (4311 [44.9%] were females). By the age of 50 years (analysis stopped at age 50 years due to the low number of participants older than that age), the cumulative incidence of major adverse cardiovascular events among survivors was 17·7% (95% CI 15·9-19·5) compared with 0·9% (0·0-2·1) in the community controls. The cumulative burden of major adverse cardiovascular events in survivors was 0·26 (95% CI 0·23-0·29) events per survivor compared with 0·009 (0·000-0·021) events per community control participant. Increasing cumulative burden of grade 1-4 non-major adverse cardiovascular events was associated with an increased future risk of major adverse cardiovascular events (one condition: RR 4·3, 95% CI 3·1-6·0; p<0·0001; two conditions: 6·6, 4·6-9·5; p<0·0001; and three conditions: 7·7, 5·1-11·4; p<0·0001). Increased risk for major adverse cardiovascular events was observed with specific subclinical conditions (eg, grade 1 arrhythmias [RR 1·5, 95% CI 1·2-2·0; p=0·0017]), grade 2 left ventricular systolic dysfunction (2·2, 1·6-3·1; p<0·0001), grade 2 valvular disorders (2·2, 1·2-4·0; p=0·013), but not grade 1 hypercholesterolaemia, grade 1-2 hypertriglyceridaemia, or grade 1-2 vascular stenosis. INTERPRETATION: Among an ageing cohort of survivors of childhood cancer, the accumulation of non-major adverse cardiovascular events, including subclinical conditions, increased the risk of major adverse cardiovascular events and should be the focus of interventions for early detection and prevention of major adverse cardiovascular events.

Assisted reproductive technology use and outcomes in childhood cancer survivors.

BACKGROUND: Treatment exposures for childhood cancer reduce ovarian reserve. However, the success of assisted reproductive technology (ART) among female survivors is not well established. METHODS: Five-year survivors of childhood cancer in the Childhood Cancer Survivor Study were linked to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System, which captures national ART outcomes. The authors assessed the live birth rate, the relative risk (RR) with 95% confidence intervals (95% CIs), and associations with treatment exposure using generalized estimating equations to account for multiple ovarian stimulations per individual. Siblings from a random sample of survivors were recruited to serve as a comparison group. RESULTS: Among 9885 female survivors, 137 (1.4%; median age at diagnosis, 10 years [range, 0-20 years]; median years of follow-up after age 18 years, 11 years [range, 2-11 years]) underwent 224 ovarian stimulations using autologous or donor eggs and/or gestational carriers (157 autologous ovarian stimulation cycles, 67 donor ovarian stimulation cycles). In siblings, 33 (1.4%) underwent 51 autologous or donor ovarian stimulations. Of those who used embryos from autologous eggs without using gestational carriers, 97 survivors underwent 155 stimulations, resulting in 49 live births, for a 31.6% chance of live birth per ovarian stimulation (vs. 38.3% for siblings; p = .39) and a 43.9% chance of live birth per transfer (vs. 50.0%; p = .33). Prior treatment with cranial radiation therapy (RR, 0.44; 95% CI, 0.20-0.97) and pelvic radiation therapy (RR, 0.33; 95% CI, 0.15-0.73) resulted in a reduced chance of live birth compared with siblings. The likelihood of live birth after ART treatment in survivors was not affected by alkylator exposure (cyclophosphamide-equivalent dose, ≥8000 mg/m2 vs. none; RR, 1.04; 95% CI, 0.52-2.05). CONCLUSIONS: Childhood cancer survivors are as likely to undergo treatment using ART as sibling controls. The success of ART treatment was not reduced after alkylator exposure. The results from the current study provide needed guidance on the use of ART in this population.

Financial hardship among siblings of long-term survivors of childhood cancer: A Childhood Cancer Survivor Study report.

BACKGROUND: Siblings of children with cancer may experience adverse household economic consequences, but their financial outcomes in adulthood are unknown. METHODS: A total of 880 siblings (aged 18-64 years) of adult-aged childhood cancer survivors were surveyed to estimate the prevalence of financial hardship by three established domains (behavioral, material, and psychological). For individual financial hardship items matching the contemporaneous National Health Interview Survey or Behavioral Risk Factor Surveillance System, siblings were compared with the general population by calculating adjusted prevalence odds ratios (ORs) to sample-weighted responses. Multivariable logistic regression models examined associations between sibling characteristics and each hardship domain and between sibling hardship and survivors' cancer/treatment characteristics. RESULTS: Behavioral, material, and psychological hardship was reported by 24%, 35%, and 28%, respectively. Compared with national survey respondents, siblings were more likely to report worries about medical bills (OR, 1.14; 95% confidence interval [CI], 1.06-1.22), difficulty affording nutritious foods (OR, 1.79; 95% CI, 1.54-2.07), and forgoing needed medical care (OR, 1.38; 95% CI, 1.10-1.73), prescription medications (OR, 2.52; 95% CI, 1.99-3.20), and dental care (OR, 1.34; 95% CI, 1.15-1.57) because of cost. Sibling characteristics associated with reporting financial hardship in one or more domains included female sex, older age, chronic health conditions, lower income, not having health insurance, high out-of-pocket medical expenditures, and nonmedical/nonhome debt. No survivor cancer/treatment characteristics were associated with sibling financial hardship. CONCLUSIONS: Adult siblings of childhood cancer survivors were more likely to experience financial hardship compared with the general population. Childhood cancer may adversely affect entire households, with potentially lasting implications.

Specific causes of excess late mortality and association with modifiable risk factors among survivors of childhood cancer: a report from the Childhood Cancer Survivor Study cohort.

BACKGROUND: 5-year survival after childhood cancer does not fully describe life-years lost due to childhood cancer because there are a large number of deaths occurring beyond 5-years (late mortality) related to cancer and cancer treatment. Specific causes of health-related (non-recurrence, non-external) late mortality and risk reduction through modifiable lifestyle and cardiovascular risk factors are not well described. Through using a well-characterised cohort of 5-year survivors of the most common childhood cancers, we evaluated specific health-related causes of late mortality and excess deaths compared with the general US population and identified targets to reduce future risk. METHODS: In this multi-institutional, hospital-based, retrospective cohort study, late mortality (death ≥5 years from diagnosis) and specific causes of death were evaluated in 34 230 5-year survivors of childhood cancer diagnosed at an age younger than 21 years from 1970 to 1999 at 31 institutions in the USA and Canada; median follow-up from diagnosis was 29 years (range 5-48) in the Childhood Cancer Survivor Study. Demographic, self-reported modifiable lifestyle (ie, smoking, alcohol, physical activity, and BMI) and cardiovascular risk factors (ie, hypertension, diabetes, and dyslipidaemia) associated with health-related mortality (which excludes death from primary cancer and external causes and includes death from late effects of cancer therapy) were evaluated. FINDINGS: 40-year cumulative all-cause mortality was 23·3% (95% CI 22·7-24·0), with 3061 (51·2%) of 5916 deaths from health-related causes. Survivors 40 years or more from diagnosis experienced 131 excess health-related deaths per 10 000 person-years (95% CI 111-163), including those due to the top three causes of health-related death in the general population: cancer (absolute excess risk per 10 000 person-years 54, 95% CI 41-68), heart disease (27, 18-38), and cerebrovascular disease (10, 5-17). Healthy lifestyle and absence of hypertension and diabetes were each associated with a 20-30% reduction in health-related mortality independent of other factors (all p values ≤0·002). INTERPRETATION: Survivors of childhood cancer are at excess risk of late mortality even 40 years from diagnosis, due to many of the leading causes of death in the US population. Modifiable lifestyle and cardiovascular risk factors associated with reduced risk for late mortality should be part of future interventions.

Modifiable risk factors for neurocognitive and psychosocial problems after Hodgkin lymphoma.

Long-term survivors of childhood Hodgkin lymphoma (HL) experience a high burden of chronic health morbidities. Correlates of neurocognitive and psychosocial morbidity have not been well established. A total of 1760 survivors of HL (mean ± SD age, 37.5 ± 6.0 years; time since diagnosis, 23.6 ± 4.7 years; 52.1% female) and 3180 siblings (mean age, 33.2 ± 8.5 years; 54.5% female) completed cross-sectional surveys assessing neurocognitive function, emotional distress, quality of life, social attainment, smoking, and physical activity. Treatment exposures were abstracted from medical records. Chronic health conditions were graded according to the National Cancer Institute's Common Terminology Criteria for Adverse Events version 4.3 (1 = mild, 2 = moderate, 3 = severe/disabling, and 4 = life-threatening). Multivariable analyses, adjusted for age, sex, and race, estimated relative risk (RR) of impairment in survivors vs siblings and, among survivors, risk of impairment associated with demographic, clinical, treatment, and grade 2 or higher chronic health conditions. Compared with siblings, survivors had significantly higher risk (all, P < .05) of neurocognitive impairment (eg, memory, 8.1% vs 5.7%), anxiety (7.0% vs 5.4%), depression (9.1% vs 7%), unemployment (9.6% vs 4.4%), and impaired physical/mental quality of life (eg, physical function, 11.2% vs 3.0%). Smoking was associated with a higher risk of impairment in task efficiency (RR, 1.56; 95% confidence interval [CI], 1.02-2.39), emotional regulation (RR, 1.84; 95% CI, 1.35-2.49), anxiety (RR, 2.43; 95% CI, 1.51-3.93), and depression (RR, 2.73; 95% CI, 1.85-4.04). Meeting the exercise guidelines of the Centers for Disease Control and Prevention was associated with a lower risk of impairment in task efficiency (RR, 0.70; 95% CI, 0.52-0.95), organization (RR, 0.60; 95% CI, 0.45-0.80), depression (RR, 0.66; 95% CI, 0.48-0.92), and multiple quality of life domains. Cardiovascular and neurologic conditions were associated with impairment in nearly all domains. Survivors of HL are at elevated risk for neurocognitive and psychosocial impairment, and risk is associated with modifiable factors that provide targets for interventions to improve long-term functional outcomes.

Treatment response to durvalumab plus tremelimumab after progression with previous immune checkpoint inhibitor in unresectable hepatocellular carcinoma.

Although immune checkpoint inhibitors (ICI) are used for unresectable hepatocellular carcinoma (HCC), it is unclear whether sequential ICI treatment-durvalumab plus tremelimumab (DT) after progression on atezolizumab plus bevacizumab (AB)-is effective for HCC. In this nationwide multicenter study, we aimed to investigate the effect of DT treatment based on the timing of treatment. A total of 85 patients receiving DT treatment were enrolled. The primary endpoint is treatment response at week 8 among patients receiving first-line DT treatment, those receiving second-line or later treatment without prior AB therapy, and those receiving second-line or later treatment with prior AB therapy. Objective response rates (ORRs) in patients with first-line treatment, second-line treatment without AB, and second-line treatment with prior AB were 44%, 54%, and 5%, respectively (p < 0.001). Similarly, disease control rates (DCRs) were 69%, 91%, and 26%, respectively (p < 0.001). ORR and DCR were significantly lower in patients with prior AB treatment. Progression free survival (PFS) was significantly shortened in patients receiving second-line therapy following prior AB treatment and an adjusted hazard ratio (95% confidence interval) in those patients for PFS, using first-line therapy as a reference, was 2.35 (1.1-5.1, p = 0.03). In conclusion, the impact of DT sequencing following AB treatment was limited. However, even after second-line treatment, the treatment effect can be equivalent to that of first-line treatment in cases with no history of AB treatment. Thus, prior treatment history should be taken into account when initiating DT treatment.

Ramucirumab for advanced hepatocellular carcinoma in the current real world: a Japanese single-arm study post-REACH-2 (The R-evolution study).

This study aimed to complement the results of the REACH-2 study by prospectively evaluating the safety and efficacy of ramucirumab in advanced hepatocellular carcinoma (HCC) in a real-world setting. This was an open-label, nonrandomized, multicenter, prospective study conducted at 13 institutions in Japan (jRCTs031190236). The study included Child-Pugh Class A patients with advanced HCC who had received pretreatment with atezolizumab plus bevacizumab (Atez/Bev) or lenvatinib. Ramucirumab was introduced as a second-line treatment after Atez/Bev or lenvatinib and as a third-line treatment after Atez/Bev and lenvatinib. Between May 2020 and July 2022, we enrolled 19 patients, including 17 who received ramucirumab. Additionally, seven patients received lenvatinib, another seven patients received Atez/Bev, and three patients received Atez/Bev followed by lenvatinib as prior treatment. The primary endpoint was a 6-month progression-free survival (PFS) rate, which was 14.3%. The median PFS and overall survival were 3.7 and 12.0 months, respectively. The most common grade ≥ 3 adverse events (AEs) were hypertension (23.5%), proteinuria (17.6%), and neutropenia (11.8%). The discontinuation rate due to AEs was 29.4%. Six patients progressed from Child-Pugh A to B after treatment with ramucirumab. Thirteen patients were eligible for post-ramucirumab treatment, including systemic therapy. Despite the limited number of patients, the efficacy of ramucirumab was comparable to that observed in the REACH-2 study when used after lenvatinib and Atez/Bev. However, the incidence of AEs was higher than that in the REACH-2 study.

Viral eradication reduces all-cause mortality in patients with chronic hepatitis C virus infection who had received direct-acting antiviral therapy.

BACKGROUND AND AIMS: The impact of hepatitis C virus (HCV) eradication via direct-acting antiviral (DAA) therapy on overall mortality, particularly non-liver-related mortality, is understudied. METHODS: We recruited 4180 patients with chronic HCV infection who achieved sustained virological response (SVR) (HCV eradication) through DAA therapy (n = 2501, SVR group) or who did not receive antiviral therapy (n = 1679, non-SVR group); 1236 from each group were chosen using propensity score matching. Causes of death and all-cause mortality, including non-liver-related diseases, were investigated. RESULTS: Of the 4180 patients, 592 died during the follow-up period. In the SVR group, the mortality rates from liver-related and non-liver-related diseases were 16.5% and 83.5%, respectively. Compared to the non-SVR group, mortality rates from liver-related and non-liver-related diseases were 50.1% and 49.9%, respectively (p < .001). In non-cirrhotic patients, multivariable analysis revealed that SVR was an independent factor associated with both liver-related (hazard ratio [HR], .251; 95% confidence interval [CI], .092-.686) and non-liver-related (HR, .641; 95% CI, .415-.990) mortalities. In cirrhotic patients, multivariable analysis revealed that SVR remained an independent factor significantly associated with liver-related mortality (HR, .151; 95% CI, .081-.279). In propensity score-matched patients, the eradication of HCV (SVR group) decreased both liver-related (p < .001) and non-liver-related mortality (p = .008) rates compared to persistent HCV infection (non-SVR group). CONCLUSIONS: The elimination of HCV via DAA therapy reduced not only liver-related mortality but also non-liver-related mortality in patients with chronic HCV.

Association analysis of self-reported outcomes with a validated subset.

In health-science research, outcomes ascertained through surveys and interviews are subject to potential bias with respect to the true outcome status, which is only ascertainable with clinical and laboratory assessment. This measurement error may lead to biased inference when evaluating associations between exposures and outcomes of interest. Here, we consider a cohort study in which the outcome of interest is ascertained via questionnaire, subject to imperfect ascertainment, but where a subset of participants also have a clinically assessed, validated outcome available. This presents a methodological opportunity to address potential bias. Specifically, we constructed the likelihood in two parts, one using the validated subset and the other using a subset without validation. This work expands on that proposed by Pepe and enables inference with standard statistical software. Weighted generalized linear model estimates for our method and maximum likelihood estimates (MLE) for Pepe's method were computed, and the statistical inference was based on the standard large-sample likelihood theory. We compare the finite sample performance of two approaches through Monte Carlo simulations. This methodological work was motivated by a large cohort study of long-term childhood cancer survivors, allowing us to provide a relevant application example where we examined the association between clinical factors and chronic health conditions.

Job lock among survivors of childhood cancer and their spouses post Affordable Care Act implementation: A Childhood Cancer Survivor Study brief report.

It is unknown how common job lock (i.e., staying at job to maintain health insurance) remains among childhood cancer survivors after Affordable Care Act (ACA) implementation in 2010. We examined prevalence of and factors associated with job lock using a cross-sectional survey from the Childhood Cancer Survivor Study (3503 survivors; 942 siblings). Survivor, spousal, and any survivor/spouse job lock were more frequently reported by survivors than siblings. Survivor job lock/any job lock was associated with older age, low income, severe chronic conditions, and debt/inability to pay debt. Job lock remains more common among survivors than siblings after ACA implementation.

Long-term outcomes among survivors of childhood osteosarcoma: A report from the Childhood Cancer Survivor Study (CCSS).

PURPOSE: Treatment strategies for osteosarcoma evolving between 1970 and 1999 improved 5-year survival and continue as standard of care today. This report evaluates the impact of these evolving therapies on long-term health outcomes. METHODS: Five-year survivors of childhood osteosarcoma in CCSS treated from 1970 to 1999 were evaluated for late (>5 years from diagnosis) mortality, chronic health conditions (CHCs), and health status using piecewise-exponential and logistical models. Comparisons were made between survivors and siblings without cancer, and among survivors examining historical and current standard chemotherapies (e.g., methotrexate/doxorubicin/cisplatin [MAP] vs. others), specific chemotherapy agents and surgical approaches (amputation vs. limb salvage [LS]). Models were evaluated adjusting for attained age, sex, race, ethnicity, and age at diagnosis. RESULTS: A total of 1257 survivors of osteosarcoma were followed on average for 24.4 years. Twenty-year all-cause late mortality was 13.3% (95% confidence interval [CI]: 11.7%-14.9%) overall and 11.7% (95% CI: 6.9%-16.5%) for the subset treated with MAP plus LS. Survivors were at higher risk of CHCs (rate ratio [RR] 3.7, 95% CI: 3.2-4.3) than the sibling cohort, most notably having more serious cardiac, musculoskeletal, and hearing CHCs. Within the survivor cohort, the risk of severe CHCs was twice as high with MAP versus no chemotherapy (RR 2.1, 95% CI: 1.3-3.4). Compared with primary amputation, serious musculoskeletal CHCs were higher after LS (RR 6.6, 95% CI: 3.6-13.4), without discernable differences in health status. CONCLUSION: Contemporary osteosarcoma therapy with MAP plus LS, while improving 5-year disease-free survival, continues to be associated with a high burden of late mortality, CHCs, and health status limitations.

Keratinocyte carcinomas in survivors of childhood cancer: A report from the childhood cancer survivor study.

BACKGROUND: Childhood cancer survivors (CCS) are at increased risk for keratinocyte carcinomas (KC) however, the long-term incidence of single and multiple KC is not well established. OBJECTIVE: Identify risk factors and quantify KC cumulative incidence and multiple-incidence burden in CCS. METHODS: KC were identified among Childhood Cancer Survivor Study participants, a cohort of 5-year cancer survivors diagnosed <21 years of age between 1970 and 1999 in North America. Cumulative incidence was estimated and multivariable models assessed relative rates of KC associated with survivor and treatment characteristics. RESULTS: Among 25,658 participants, 1446 developed 5363 KC (93.5% basal cell carcinoma, 6.7% squamous cell carcinoma; mean age 37.0 years (range 7.3-67.4), mean latency 25.7 years; 95.3% White and 88.4% with radiotherapy). Mean lesion count was 3.7 with 26.1% experiencing ≥4. Radiotherapy imparted a 4.5-fold increase in the rate of any KC and 9.4-fold increase in the rate of ≥4 KC. Allogeneic and autologous hematopoietic cell transplant were associated with a 3.4- and 2.3-fold increased rate of KC, respectively. LIMITATIONS: Participant self-reporting of some data including race without skin phototype and past medical history may have impacted analysis. CONCLUSIONS: The burden of KC in CCS remains high, but predictable risk factors should guide screening.

Glycemic control target for liver and cardiovascular events risk in metabolic dysfunction-associated steatotic liver disease.

AIMS: Optimizing glycemic control may prevent liver-related events and major adverse cardiovascular events (MACE) in patients with metabolic dysfunction-associated steatotic liver disease (MASLD). However, the optimal hemoglobin A1c (HbA1c) threshold associated with a lower risk of complications, particularly liver-related events as well as MACE is unknown. METHODS: We investigated a nationwide population-based cohort and identified 633 279 patients with MASLD, with a mean follow-up of 4.2 years. Hemoglobin A1c levels were measured annually. The primary endpoint was the risk of liver-related events and MACE and to determine the optimal HbA1c level associated with the risk of complications. RESULTS: Mean HbA1c (per 1%) was associated with liver-related events (subdistribution hazard ratio [sHR] 1.26; 95% confidence interval [CI], 1.12-1.42) as well as MACE (sHR 1.36; 95% CI, 1.32-1.41) after adjustment for confounders. Multivariable sHR (95% CI) for HbA1c of <5.0%, 6.0%-6.9%, 7.0%-7.9%, 8.0%-8.9%, and ≥9.0% (reference, 5.0%-5.9%) were 14 (9.1-22), 1.70 (1.2-2.3), 3.32 (2.3-4.8), 3.81 (2.1-6.8), and 4.83 (2.4-9.6) for liver-related events, and 1.24 (0.8-1.8), 1.27 (1.2-1.4), 1.70 (1.5-2.0), 2.36 (1.9-2.9), and 4.17 (3.5-5.0) for MACE. An HbA1c level of 7% was selected as the optimal threshold for predicting complications (sHR 2.40 [1.8-3.2] for liver-related events and 1.98 [1.8-2.2] for MACE). CONCLUSION: The risk of liver-related events as well as MACE increased in a dose-dependent fashion with an increase in HbA1c levels, except for patients with HbA1c <5.0% for liver-related events. An HbA1c level of 7% was the optimal threshold associated with a lower risk of complications and may be utilized as a target for glycemic control in patients with MASLD.

Concordance between metabolic dysfunction-associated steatotic liver disease and nonalcoholic fatty liver disease.

AIM: A multisociety consensus group proposed a new nomenclature for metabolic dysfunction-associated steatotic liver disease (MASLD). Although patients with nonalcoholic fatty liver disease (NAFLD) are expected to be reclassified as patients with MASLD under the new nomenclature, the concordance between MASLD and NAFLD remains unclear. Moreover, waist circumference could be adjusted by ethnicity for diagnosing MASLD; however, there are limited data on the optimal waist circumference in the Japanese population. METHODS: This cross-sectional study was conducted on 3709 Japanese patients with NAFLD. The primary endpoint was the prevalence of MASLD in patients with NAFLD. The difference between the original waist circumference criteria (>94 cm for men and >80 cm for women) and the Japanese metabolic syndrome criteria (≥85 cm for men and ≥90 cm for women) for concordance between NAFLD and MASLD was also investigated. RESULTS: According to the original criteria, the prevalence of MASLD in patients with NAFLD was 96.7%. Similarly, according to the Japanese waist circumference criteria, 96.2% of patients with NAFLD could be reclassified as those with MASLD. The concordance rate was significantly higher in the original criteria than in the Japanese criteria (p = 0.02). CONCLUSIONS: NAFLD could be considered MASLD using the original MASLD criteria in the Japanese population, and insights from NAFLD research could be applied to MASLD.

Impact of immune-related adverse events in patients with hepatocellular carcinoma treated with atezolizumab plus bevacizumab.

BACKGROUND AND AIM: Immune checkpoint inhibitors pose the risk of immune-related adverse events (irAEs). Recent data suggest that irAEs may be associated with a favorable prognosis. This study aimed to investigate and analyze the association between these adverse events and the clinical benefits in patients with unresectable hepatocellular carcinoma. METHODS: The study enrolled 130 patients with advanced hepatocellular carcinoma treated with atezolizumab plus bevacizumab between November 2020 and January 2023 at a single center. The relationship between irAEs and both response rate and post-treatment outcomes was investigated. RESULTS: Out of the 130 patients, irAEs developed in 36 (27.7%) patients. The irAE group exhibited a significantly longer progression-free survival (PFS) than the non-irAE group, with a median PFS of 8.9 compared with 4.6 months (P < 0.01). No difference was found in the overall survival between the irAE and non-irAE groups. The irAE group demonstrated significantly higher disease control rate (DCR) than the non-irAE group (97.0% vs 65.5%, P < 0.01). The analysis by irAE severity revealed that the grade 1/2 group exhibited significantly longer PFS (7.9 vs 4.6 months, P = 0.007) and higher DCR (100% vs 65.5%, P < 0.01) than the non-irAE group. Furthermore, hypothyroidism correlated with a favorable PFS (8.9 vs 5.4 months, P = 0.02), DCR (100% vs 71.3%, P = 0.03), and overall response rate (58.3% vs 18.5%, P = 0.005). CONCLUSION: The presence of irAEs is associated with prolonged PFS and higher DCR. Specifically, mild irAEs (grade 1/2) and hypothyroidism displayed prolonged PFS and higher DCR.

Development and validation of age-specific risk prediction models for primary ovarian insufficiency in long-term survivors of childhood cancer: a report from the Childhood Cancer Survivor Study and St Jude Lifetime Cohort.

BACKGROUND: Female survivors of childhood cancer are at risk for primary ovarian insufficiency (POI), defined as the cessation of gonadal function before the age of 40 years. We aimed to develop and validate models to predict age-specific POI risk among long-term survivors of childhood cancer. METHODS: To develop models to predict age-specific POI risk for the ages of 21-40 years, we used data from the Childhood Cancer Survivor Study (CCSS). Female survivors aged 18 years or older at their latest follow-up, with self-reported menstrual history information and free of subsequent malignant neoplasms within 5 years of diagnosis, were included. We evaluated models that used algorithms based on statistical or machine learning to consider all predictors, including cancer treatments. Cross-validated prediction performance metrics (eg, area under the receiver operating characteristic curve [AUROC]) were compared to select the best-performing models. For external validation of the models, we used data from 5-year survivors in the St Jude Lifetime Cohort (SJLIFE) with ovarian status clinically ascertained using hormone measurements (menopause defined by follicle stimulating hormone >30 mIU/mL and oestradiol <17 pg/mL) and medical chart or questionnaire review. We also evaluated an SJLIFE-based polygenic risk score for POI among 1985 CCSS survivors with genotype data available. FINDINGS: 7891 female CCSS survivors (922 with POI) were included in the development of the POI risk prediction model, and 1349 female SJLIFE survivors (101 with POI) were included in the validation study. Median follow-up from cancer diagnosis was 23·7 years (IQR 18·3-30·0) in CCSS and 15·1 years (10·4-22·9) in SJLIFE. Between the ages of 21 and 40 years, POI prevalence increased from 7·9% (95% CI 7·3-8·5) to 18·6% (17·3-20·0) in CCSS and 7·3% (5·8-8·9) to 14·9% (11·6-19·1) in SJLIFE. Age-specific logistic regression models considering ovarian radiation dosimetry or prescribed pelvic and abdominal radiation dose, along with individual chemotherapy predictors, performed well in CCSS. In the SJLIFE validation, the prescribed radiation dose model performed well (AUROC 0·88-0·95), as did a simpler model that considered any exposures to pelvic or abdominal radiotherapy or alkylators (0·82-0·90). Addition of the polygenic risk predictor significantly improved the average positive predictive value (from 0·76 [95% CI 0·63-0·89] to 0·87 [0·80-0·94]; p=0·029) among CCSS survivors treated with ovarian radiation and chemotherapy. INTERPRETATION: POI risk prediction models using treatment information showed robust prediction performance in adult survivors of childhood cancer.

Cumulative burden of late, major surgical intervention in survivors of childhood cancer: a report from the Childhood Cancer Survivor Study (CCSS) cohort.

BACKGROUND: Multimodal cancer therapy places childhood cancer survivors at increased risk for chronic health conditions, subsequent malignancies, and premature mortality as they age. We aimed to estimate the cumulative burden of late (>5 years from cancer diagnosis), major surgical interventions among childhood cancer survivors, compared with their siblings, and to examine associations between specific childhood cancer treatments and the burden of late surgical interventions. METHODS: We analysed data from the Childhood Cancer Survivor Study (CCSS), a retrospective cohort study with longitudinal prospective follow-up of 5-year survivors of childhood cancer (diagnosed before age 21 years) treated at 31 institutions in the USA, with a comparison group of nearest-age siblings of survivors selected by simple random sampling. The primary outcome was any self-reported late, major surgical intervention (defined as any anaesthesia-requiring operation) occurring 5 years or more after the primary cancer diagnosis. The cumulative burden was assessed with mean cumulative counts (MCC) of late, major surgical interventions. Piecewise exponential regression models with calculation of adjusted rate ratios (RRs) evaluated associations between treatment exposures and late, major surgical interventions. FINDINGS: Between Jan 1, 1970, and Dec 31, 1999, 25 656 survivors were diagnosed (13 721 male, 11 935 female; median follow-up 21·8 years [IQR 16·5-28·4]; median age at diagnosis 6·1 years [3·0-12·4]); 5045 nearest-age siblings were also included as a comparison group. Survivors underwent 28 202 late, major surgical interventions and siblings underwent 4110 late, major surgical interventions. The 35-year MCC of a late, major surgical intervention was 206·7 per 100 survivors (95% CI 202·7-210·8) and 128·9 per 100 siblings (123·0-134·7). The likelihood of a late, major surgical intervention was higher in survivors versus siblings (adjusted RR 1·8, 95% CI 1·7-1·9) and in female versus male survivors (1·4; 1·4-1·5). Survivors diagnosed in the 1990s (adjusted RR 1·4, 95% CI 1·3-1·5) had an increased likelihood of late surgery compared with those diagnosed in the 1970s. Survivors received late interventions more frequently than siblings in most anatomical regions or organ systems, including CNS (adjusted RR 16·9, 95% CI 9·4-30·4), endocrine (6·7, 5·2-8·7), cardiovascular (6·6, 5·2-8·3), respiratory (5·3, 3·4-8·2), spine (2·4, 1·8-3·2), breast (2·1, 1·7-2·6), renal or urinary (2·0, 1·5-2·6), musculoskeletal (1·5, 1·4-1·7), gastrointestinal (1·4, 1·3-1·6), and head and neck (1·2, 1·1-1·4) interventions. Survivors of Hodgkin lymphoma (35-year MCC 333·3 [95% CI 320·1-346·6] per 100 survivors), Ewing sarcoma (322·9 [294·5-351·3] per 100 survivors), and osteosarcoma (269·6 [250·1-289·2] per 100 survivors) had the highest cumulative burdens of late, major surgical interventions. Locoregional surgery or radiotherapy cancer treatment were associated with undergoing late surgical intervention in the same body region or organ system. INTERPRETATION: Childhood cancer survivors have a significant burden of late, major surgical interventions, a late effect that has previously been poorly quantified. Survivors would benefit from regular health-care evaluations aiming to anticipate impending surgical issues and to intervene early in the disease course when feasible.

Cancer germline predisposing variants and late mortality from subsequent malignant neoplasms among long-term childhood cancer survivors: a report from the St Jude Lifetime Cohort and the Childhood Cancer Survivor Study.

BACKGROUND: Carriers of cancer predisposing variants are at an increased risk of developing subsequent malignant neoplasms among those who have survived childhood cancer. We aimed to investigate whether cancer predisposing variants contribute to the risk of subsequent malignant neoplasm-related late mortality (5 years or more after diagnosis). METHODS: In this analysis, data were included from two retrospective cohort studies, St Jude Lifetime Cohort (SJLIFE) and the Childhood Cancer Survivor Study (CCSS), with prospective follow-up of patients who were alive for at least 5 years after diagnosis with childhood cancer (ie, long-term childhood cancer survivors) with corresponding germline whole genome or whole exome sequencing data. Cancer predisposing variants affecting 60 genes associated with well-established autosomal-dominant cancer-predisposition syndromes were characterised. Subsequent malignant neoplasms were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 4.03 with modifications. Cause-specific late mortality was based on linkage with the US National Death Index and systematic cohort follow up. Fine-Gray subdistribution hazard models were used to estimate subsequent malignant neoplasm-related late mortality starting from the first biospecimen collection, treating non-subsequent malignant neoplasm-related deaths as a competing risk, adjusting for genetic ancestry, sex, age at diagnosis, and cancer treatment exposures. SJLIFE (NCT00760656) and CCSS (NCT01120353) are registered with ClinicalTrials.gov. FINDINGS: 12 469 (6172 male and 6297 female) participants were included, 4402 from the SJLIFE cohort (median follow-up time since collection of the first biospecimen 7·4 years [IQR 3·1-9·4]) and 8067 from the CCSS cohort (median follow-up time since collection of the first biospecimen 12·6 years [2·2-16·6]). 641 (5·1%) of 12 469 participants carried cancer predisposing variants (294 [6·7%] in the SJLIFE cohort and 347 [4·3%] in the CCSS cohort), which were significantly associated with an increased severity of subsequent malignant neoplasms (CTCAE grade ≥4 vs grade <4: odds ratio 2·15, 95% CI 1·18-4·19, p=0·0085). 263 (2·1%) subsequent malignant neoplasm-related deaths (44 [1·0%] in the SJLIFE cohort; and 219 [2·7%] in the CCSS cohort) and 426 (3·4%) other-cause deaths (103 [2·3%] in SJLIFE; and 323 [4·0%] in CCSS) occurred. Cumulative subsequent malignant neoplasm-related mortality at 10 years after the first biospecimen collection in carriers of cancer predisposing variants was 3·7% (95% CI 1·2-8·5) in SJLIFE and 6·9% (4·1-10·7) in CCSS versus 1·5% (1·0-2·1) in SJLIFE and 2·1% (1·7-2·5) in CCSS in non-carriers. Carrying a cancer predisposing variant was associated with an increased risk of subsequent malignant neoplasm-related mortality (SJLIFE: subdistribution hazard ratio 3·40 [95% CI 1·37-8·43]; p=0·0082; CCSS: 3·58 [2·27-5·63]; p<0·0001). INTERPRETATION: Identifying participants at increased risk of subsequent malignant neoplasms via genetic counselling and clinical genetic testing for cancer predisposing variants and implementing early personalised cancer surveillance and prevention strategies might reduce the substantial subsequent malignant neoplasm-related mortality burden.
