Increasing number of older adults with Plasma Cell Disorders (PCDs) are receiving autologous stem cell transplant (ASCT) in the US. Hospital associated disability (HAD) is a common complication associated with acute care hospitalization among older adults. To estimate the prevalence and prognostic significance of HAD among older adults with MM undergoing ASCT. This retrospective cohort study used consecutive adults ≥ 18 y with PCD receiving ASCT at a single institution between 1/2013 and 5/2023. Trained nursing staff assessed Katz Activities of Daily Living (ADL) at admission and every 3 days thereafter under our Virtual Acute Care for Elders program. The primary outcome was development of HAD defined as ≥1 point decline on the Katz Activities of Daily Living (ADL) scale from hospital admission to discharge. We examined the association between putative risk factors such as age, Karnofsky performance status (KPS), baseline ADL score, Hematopoietic Cell Transplantation-specific Comorbidity Index (HCT-CI) and HAD using modified Poisson regression models with robust variance estimators. Subsequently, we studied the impact of HAD on downstream adverse events including 30-day readmission rates and long term survival. We included 778 adults with a median age of 62 y (QR 56-68 y), with 56% males and 55% non-Hispanic Whites. In the overall population, 112 (14.4%) developed HAD, with much higher incidence among older adults ≥ 65 y compared to those <65 y at ASCT (22% vs. 9%, Pvalue < .01). In multivariable analysis, increasing age (RR 1.56; 95% CI 1.25-1.94, per 10 y increase), female sex (RR 1.79; 95% CI 1.27-2.53) and KPS ≤ 70 (RR 2.55; 95% CI 1.32-4.94) were associated with an increased risk of developing HAD. As compared to those without, patients with HAD had a two-fold higher risk of 30-day readmission (95% CI 1.16-3.39) and a 3.7-fold increased risk of all-cause mortality (95% CI 2.15-6.22). Nearly one in 4 older adults ≥ 65 y developed HAD while undergoing ASCT which was associated with a two-fold increased risk of 30-day readmission. Interventions to prevent HAD and its downstream consequences are critically needed.

We examined the prevalence, risk factors, and association between pre-frailty and subsequent mortality after blood or marrow transplantation (BMT). Study participants were drawn from the BMT Survivor Study (BMTSS) and included 3346 individuals who underwent BMT between 1974 and 2014 at one of three transplant centers and survived ≥2 years post-BMT. Participants completed the BMTSS survey at a median of 9 years from BMT and were followed for subsequent mortality for a median of 5 years after survey completion. Closest-age and same-sex biological siblings also completed the survey. Previously published self-reported indices (exhaustion, weakness, low energy expenditure, slowness, unintentional weight loss) classified participants as non-frail (0–1 indices) or pre-frail (2 indices). National Death Index was used to determine vital status and cause of death. Overall, 626 (18.7%) BMT survivors were pre-frail. BMT survivors had a 3.2-fold higher odds of being pre-frail (95% CI = 1.9–5.3) compared to siblings. Compared to non-frail survivors, pre-frail survivors had higher hazards of all-cause mortality (adjusted hazard ratio [aHR] = 1.6, 95% CI = 1.4–2.0). Female sex, pre-BMT radiation, smoking, lack of exercise, anxiety, and severe/life-threatening chronic health conditions were associated with pre-frailty. The novel association between pre-frailty and subsequent mortality provides evidence for interventions as pre-frail individuals may transition back to their robust state.

Low skeletal muscle mass (LSMM) and/or, function associated with an increased risk of treatment‐related toxicities and inferior overall survival (OS) among adults with solid malignancies. However, the association between LSMM and treatment‐related toxicities among adults with haematologic malignancies remains unclear. Using a pre‐published protocol (CRD42020197814), we searched seven bibliographic databases from inception to 08/2021 for studies reporting the impact of LSMM among adults ≥18 years with a known haematologic malignancy. The primary outcome of interest was OS, and secondary outcomes included progression free survival (PFS) and non‐relapse mortality (NRM). These effect sizes were quantified in terms of hazards ratio (HR) along with 95% confidence interval (CI) and pooled across studies using a DerSimonian–Laird random‐effects model. Heterogeneity was assessed using the Cochran's Qand the I2statistic. All hypothesis testing was two‐sided with an alpha of 0.05. Of 3791 studies screened, we identified 20 studies involving 3468 patients with a mean age of 60 years; 44% were female and the most common malignancy was diffuse large B‐cell lymphoma (42%). Most studies measured muscle mass using single slice computed tomography imaging at the L3 level. The presence of LSMM was associated with worse OS (pooled HR = 1.81, 95% CI = 1.48–2.22, P< 0.001) with moderate heterogeneity (Cochran's Q, I2= 60.4%), PFS (pooled HR = 1.61, 95% CI = 1.28–2.02, P< 0.001) with moderate heterogeneity (Cochran's Q, I2= 66.0%). Similarly, LSMM was associated with worse NRM (HR = 1.72, 95% CI = 1.34–2.22, P< 0.001) with little evidence of heterogeneity (Cochran's Q, I2= 0.0%). LSMM is associated with worse survival outcomes among adults with haematologic malignancies. Further research into understanding the underlying mechanism of this association and mitigating the negative effects of LSMM among adults with haematologic malignancies is needed.

We determined the risk of late morbidity and mortality after autologous blood or marrow transplantation (BMT) for lymphoma performed before age 40. The cohort included autologous BMT recipients who had survived ≥2 years after transplantation (N= 583 [HL = 59.9%; NHL = 40.1%]) and a comparison cohort (N= 1070). Participants self-reported sociodemographics and chronic health conditions. A severity score (grade 3 [severe], 4 [life threatening] or 5 [fatal]) was assigned to the conditions using CTCAE v5.0. Logistic regression estimated the odds of grade 3–4 conditions in survivors vs. comparison subjects. Proportional subdistribution hazards models identified predictors of grade 3–5 conditions among BMT recipients. Median age at BMT was 30.0 years (range: 2.0–40.0) and median follow-up was 9.8 years (2.0–32.1). Survivors were at a 3-fold higher adjusted odds for grade 3–4 conditions (95% CI = 2.3–4.1) vs. comparison subjects. Factors associated with grade 3–5 conditions among BMT recipients included age at BMT (>30 years: adjusted hazard ratio [aHR] = 2.31; 95% CI = 1.27–4.19; reference: ≤21 years), pre-BMT radiation (aHR = 1.52; 95% CI = 1.13–2.03; reference: non-irradiated), and year of BMT (≥2000: aHR = 0.54; 95% CI = 0.34–0.85; reference: <1990). The 25 years cumulative incidence of relapse-related and non-relapse-related mortality was 18.2% and 25.9%, respectively. The high risk for late morbidity and mortality after autologous BMT for lymphoma performed at age <40 calls for long-term anticipatory risk-based follow-up.

IMPORTANCE: Little is known about the risk of post–COVID-19 multisystem inflammatory syndrome in children (MIS-C) in the setting of childhood cancer. OBJECTIVE: To evaluate factors associated with MIS-C and describe the clinical course of COVID-19 in the setting of MIS-C. DESIGN, SETTING, AND PARTICIPANTS: Multisite observational cohort study of a registry representing more than 100 US pediatric oncology sites. All included patients were registered between April 1, 2020, and May 18, 2022. Sites submitted deidentified data surrounding sociodemographics, cancer diagnosis and treatment, and COVID-19 course (symptoms, maximum support required, outcome). Patients with MIS-C (n = 24) were compared with matched controls (n = 96). Children (&lt;21 years) with cancer who developed COVID-19 while receiving cancer treatment or within 1 year of completing treatment were characterized based on their development of MIS-C. EXPOSURES: (1) Clinical and sociodemographic characteristics of children with cancer and COVID-19; and (2) MIS-C. MAIN OUTCOMES AND MEASURES: (1) Development of MIS-C among children with cancer and COVID-19; and (2) symptoms and disease severity associated with MIS-C. RESULTS: Among 2035 children with cancer and COVID-19, 24 (1.2%) developed MIS-C. COVID-19 occurred at a median (IQR) age of 12.5 (5.5-17.1) years in those with MIS-C and 11 (6-16) years among matched controls (P = .86). The majority of children with MIS-C had a hematologic cancer (83.3% [n = 20]), were publicly insured (66.7% [n = 16]), and were Hispanic (54.2% [n = 13]). Half (n = 12) had 1 or more noncancer comorbidity. Those with comorbidities were more likely to develop MIS-C than those without (odds ratio [OR], 2.5 [95% CI, 1.1-5.7]). Among children with MIS-C, 100% (n = 24) were admitted to the hospital and 54.2% (n = 13) to the intensive care unit (ICU), while COVID-19 contributed to the death of 20.1% (n = 5); cancer therapy was changed in 62.5% (n = 15). Compared with matched controls, those with MIS-C had higher odds of symptoms classified as systemic (OR, 4.7 [95% CI, 1.4-15.8]) or gastrointestinal (OR, 5.0 [95% CI, 1.7-14.6]) along with higher odds of hospitalization (OR, 42.9 [95% CI, 7.1-258]), ICU admission (OR, 11.4 [95% CI, 3.6-36.4]), and changes to cancer therapy (OR, 24.9 [95% CI, 6.5-94.8]). CONCLUSIONS AND RELEVANCE: In this cohort study among children with cancer and COVID-19, those with MIS-C had a more severe clinical course than those without MIS-C. The risk of MIS-C and its severity are important to consider as clinicians monitor patients with COVID-19. These findings can inform their conversations with families regarding COVID-19 risks and the benefits of prevention strategies that are pharmacologic (vaccination) and nonpharmacologic (masking), as well as treatment (antivirals, monoclonal antibodies).

•Children living in extreme poverty during maintenance therapy for childhood ALL experience a 1.9-fold greater hazard of relapse.•Lower proportion of children with ALL living in extreme poverty achieve critical adherence (95%) to oral mercaptopurine.

Background:There is a paucity of literature regarding health literacy in pediatric oncology. We sought to understand the relationship between health literacy and comprehension of key new diagnosis education concepts in parents of children newly diagnosed with cancer. Methods:Using data from a study evaluating a structured new diagnosis discharge teaching intervention, we performed a secondary analysis to understand the relationship between parental health literacy (Brief Health Literacy Screener: BHLS) and comprehension of six key concepts (child's diagnosis, primary oncologist, and treatment plan; seeking emergent care; fever definition; re-dosing medication). We also evaluated the association between parents self-reported sociodemographic characteristics, preferred learning style (one-item ordinal assessment) and health literacy. We tested relationships using Fisher's exact tests, independent samples t-tests, and Pearson correlations. Results:Fifty parents participated (age 35.4 ± 8.2 years [M± SD]; 86% female; 60% non-Hispanic white; 24% with ≤high school education); nine parents (18%) scored in the BHLS low literacy range; 80% correctly responded to all six items on the key concepts questionnaire (100% comprehension). Health literacy was not significantly related to 100% comprehension or to individual key concept responses, with the exception of “child's treatment plan” (correct responses: 55.6% in low vs. 100% in adequate literacy groups; p< .001). Parental sociodemographic characteristics and preferred learning styles were not significantly related to health literacy. Discussion:Despite variability in health literacy levels, 80% of the parents comprehended all key concepts, suggesting that the intervention was effective for most parents, regardless of health literacy level.

•COVID-19 infection risk is similar for long-term BMT survivors and non-BMT participants.•Among BMT survivors, COVID-19 infection risk is higher among those who are unemployed and not masking.

Background:Parents of children newly diagnosed with cancer require specialized knowledge and skills in order to safely care for their children at home. The Children's Oncology Group (COG) developed expert consensus recommendations to guide new diagnosis education; however, these recommendations have not been empirically tested. Methods:We used a sequential two-cohort study design to test a nurse-led Structured Discharge Teaching Intervention (SDTI) that operationalizes the COG expert recommendations in the setting of a tertiary children's hospital. Outcomes included parent Readiness for Hospital Discharge Scale (RHDS); Quality of Discharge Teaching Scale (QDTS); Post-Discharge Coping Difficulty (PDCD); Nurse Satisfaction; and post-discharge unplanned healthcare utilization. Results:The process for discharge education changed significantly before and after implementation of the SDTI, with significantly fewer instances of one-day discharge teaching, and higher involvement of staff nurses in teaching. Overall, parental RHDS, QDTS, and PDCD scores were similar in the unintervened and intervened cohorts. Almost 60% of patients had unplanned healthcare encounters during the first 30 days following their initial hospital discharge. Overall nurse satisfaction with the quality and process of discharge education significantly increased post-intervention. Discussion:Although the structure for and process of delivering discharge education changed significantly with implementation of the SDTI, parent RHDS and QDTS scores remained uniformly high and PDCD scores and non-preventable unplanned healthcare utilization remained similar, while nurse satisfaction with the quality and process of discharge education significantly improved, suggesting that further testing of the SDTI across diverse pediatric oncology settings is warranted.

IMPORTANCE: Survivors of blood or marrow transplant (BMT) are at increased risk of subsequent malignant neoplasms (SMNs). Cancers of the gastrointestinal (GI) system are of special interest because their clinical behavior is often aggressive, necessitating early detection by increasing awareness of high-risk populations. OBJECTIVE: To describe the risk of SMNs in the GI tract after BMT. DESIGN, SETTING, AND PARTICIPANTS: A cohort study of 6710 individuals who lived at least 2 years after BMT performed between January 1, 1974, and December 31, 2014, at City of Hope, University of Minnesota, or University of Alabama at Birmingham. End of follow-up was March 23, 2020. Data analysis was performed between September 1, 2022, and September 30, 2022. EXPOSURES: Demographic and clinical factors; therapeutic exposures before or as part of BMT. MAIN OUTCOMES AND MEASURES: Development of SMNs in the GI tract after BMT. Participants self-reported SMNs in the GI tract; these were confirmed with pathology reports, medical records, or both. For deceased patients, death records were used. Standardized incidence ratios determined excess risk of SMNs in the GI tract compared with that of the general population. Fine-Gray proportional subdistribution hazard models assessed the association between risk factors and SMNs in the GI tract. RESULTS: The cohort of 6710 individuals included 3444 (51.3%) autologous and 3266 (48.7%) allogeneic BMT recipients. A total of 3917 individuals (58.4%) were male, and the median age at BMT was 46 years (range, 0-78 years). After 62 479 person-years of follow-up, 148 patients developed SMNs in the GI tract. The standardized incidence ratios for developing specific SMNs ranged from 2.1 for colorectal cancer (95% CI, 1.6-2.8; P &lt; .001) to 7.8 for esophageal cancer (95% CI, 5.0-11.6; P &lt; .001). Exposure to cytarabine for conditioning (subdistribution hazard ratio [SHR], 3.1; 95% CI, 1.5-6.6) was associated with subsequent colorectal cancer. Compared with autologous BMT recipients, allogeneic BMT recipients with chronic graft-vs-host disease were at increased risk for esophageal cancer (SHR, 9.9; 95% CI, 3.2-30.5). Conditioning with etoposide (SHR, 2.0; 95% CI, 1.1-3.5) and pre-BMT anthracycline exposure (SHR, 5.4; 95% CI, 1.3-23.4) were associated with an increased risk of liver cancer compared with no exposure to the respective agents. CONCLUSIONS AND RELEVANCE: The findings of this cohort study are relevant for oncologists and nononcologists who care for the growing number of survivors of transplant. Awareness of subgroups of survivors of BMT at high risk for specific types of SMNs in the GI tract may influence recommendations regarding modifiable risk factors, as well as individualized screening.

Living in a disadvantaged neighborhood is associated with poor health outcomes. Blood or Marrow Transplant (BMT) survivors remain at risk of chronic health conditions requiring anticipatory management. We hypothesized that among BMT survivors, neighborhood disadvantage was associated with poor self-reported routine health care utilization and health. We leveraged data from BMTSS – a retrospective cohort study examining long-term outcomes among individuals surviving ≥2 y following BMT at three institutions between 1974 and 2014. Participants in this analysis completed the BMTSS survey (sociodemographics; chronic health conditions; time since routine check-up; self-reported health). The Area Deprivation Index (ADI) represented neighborhood disadvantage; this composite indicator of 17 census measures is a percentile rank (0 = least deprived to 100 = most deprived). Multivariable ordered logit regression adjusted for clinical factors and individual-level sociodemographics, modeling associations between ADI, time since routine check-up, and self-reported health. Among 2,857 survivors, median ADI was 24 (interquartile range: 10-46). Adjusting for self-reported individual-level socioeconomic indicators and chronic health conditions, patients in more disadvantaged neighborhoods had higher odds of reporting longer intervals since routine check-up (ORADI_continuous = 1.007, P < .001) and poorer health status (controlling for time since check-up; ORADI_continuous = 1.005, P = .003). Compared with patients living in the least disadvantaged neighborhood (ADI = 1), patients in the most disadvantaged neighborhood (ADI = 100), had twice the odds (ORADI = 1.007^99 = 2.06) of reporting no routine visits and 1.65-times the odds of reporting poor health (ORADI = 1.005^99 = 1.65). In BMT survivors, access to health care and health status are associated with area disadvantage. These findings may inform strategies to address long-term care coordination and retention for vulnerable survivors.

Background: Women treated with therapeutic chest radiation may develop breast cancer. Purpose: To summarize breast cancer risk and breast cancer surveillance in women after chest radiation for pediatric or young adult cancer. Data Sources: Studies from MEDLINE, EMBASE, the Cochrane Library, and CINAHL (1966 to December 2008). Study Selection: Articles were selected to answer any of 3 questions: What is the incidence and excess risk for breast cancer in women after chest radiation for pediatric or young adult cancer? For these women, are the clinical characteristics of breast cancer and the outcomes after therapy different from those of women with sporadic breast cancer in the general population? What are the potential benefits and harms associated with breast cancer surveillance among women exposed to chest radiation? Data Extraction: Three investigators independently extracted data and assessed study quality. Data Synthesis: Standardized incidence ratios ranged from 13.3 to 55.5; cumulative incidence of breast cancer by age 40 to 45 years ranged from 13% to 20%. Risk for breast cancer increased linearly with chest radiation dose. Available limited evidence suggests that the characteristics of breast cancer in these women and the outcomes after diagnosis are similar to those of women in the general population; mammography can detect breast cancer, although sensitivity is limited. Limitation: The quality of evidence for key questions 2 and 3 is limited by substantial study heterogeneity, variation in study design, and small sample size. Conclusion: Women treated with chest radiation have a substantially elevated risk for breast cancer at a young age, which does not seem to plateau. In this high-risk population, there seems to be a benefit associated with early detection. Further research is required to better define the harms and benefits of lifelong surveillance.

Survivors of childhood hematologic malignancies are at a substantially higher risk of developing subsequent neoplasms (SNs) when compared with the general population. SNs commonly observed in this population include basal cell carcinoma, brain tumors, thyroid cancer, breast cancer, bone tumors, and sarcoma. Radiation is the primary therapeutic exposure associated with the development of these SNs. There is emerging evidence of an association between chemotherapeutic exposures (alkylating agents/anthracyclines) and the development of SNs. Despite a strong dose-dependent association between therapeutic exposures and SN risk, there is significant interindividual variability in the risk for SNs for any given dose of therapeutic exposure. This interindividual variability in risk suggests the role of genetic susceptibility. This article describes the clinical and molecular epidemiology of SNs commonly observed in survivors of childhood hematologic malignancies and also highlights some of the work focusing on the development of risk prediction models to facilitate targeted interventions.

IMPORTANCE: Breast cancer is the most common invasive subsequent malignant disease in childhood cancer survivors, though limited data exist on changes in breast cancer rates as primary cancer treatments have evolved. OBJECTIVE: To quantify the association between temporal changes in cancer treatment over 3 decades and subsequent breast cancer risk. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study of 5-year cancer survivors diagnosed when younger than 21 years between 1970 and 1999, with follow-up through December 5, 2020. EXPOSURES: Radiation and chemotherapy dose changes over time. MAIN OUTCOMES AND MEASURES: Breast cancer cumulative incidence rates and age-specific standardized incidence ratios (SIRs) compared across treatment decades (1970-1999). Piecewise exponential models estimated invasive breast cancer and ductal carcinoma in situ (DCIS) risk and associations with treatment exposures, adjusted for age at childhood cancer diagnosis and attained age. RESULTS: Among 11 550 female survivors (median age, 34.2 years; range 5.6-66.8 years), 489 developed 583 breast cancers: 427 invasive, 156 DCIS. Cumulative incidence was 8.1% (95% CI, 7.3%-9.0%) by age 45 years. An increased breast cancer risk (SIR, 6.6; 95% CI, 6.1-7.2) was observed for survivors compared with the age-sex-calendar-year-matched general population. Changes in therapy by decade included reduced rates of chest (34% in the 1970s, 22% in the 1980s, and 17% in the 1990s) and pelvic radiotherapy (26%, 17%, and 13% respectively) and increased rates of anthracycline chemotherapy exposures (30%, 51%, and 64%, respectively). Adjusting for age and age at diagnosis, the invasive breast cancer rate decreased 18% every 5 years of primary cancer diagnosis era (rate ratio [RR], 0.82; 95% CI, 0.74-0.90). When accounting for chest radiotherapy exposure, the decline attenuated to an 11% decrease every 5 years (RR, 0.89; 95% CI, 0.81-0.99). When additionally adjusted for anthracycline dose and pelvic radiotherapy, the decline every 5 years increased to 14% (RR, 0.86; 95% CI, 0.77-0.96). Although SIRs of DCIS generally increased over time, there were no statistically significant changes in incidence. CONCLUSIONS AND RELEVANCE: Invasive breast cancer rates in childhood cancer survivors have declined with time, especially in those younger than 40 years. This appears largely associated with the reduced use of chest radiation therapy, but was tempered by concurrent changes in other therapies.

Cognitive impairment is prevalent in blood or marrow transplantation (BMT) recipients, albeit with inter-individual variability. We conducted a genome-wide association study of objective cognitive function assessed longitudinally in 239 adult BMT recipients for discovery and replicated in an independent cohort of 540 BMT survivors. Weighted genome-wide polygenic risk scores (PRS) were constructed using linkage disequilibrium pruned significant SNPs. Forty-four genome-wide significant SNPs were identified using additive (n= 3); codominant (n= 20) and genotype models (n= 21). Each additional copy of a risk allele was associated with a 0.28-point (p= 1.07 × 10−8) to a 1.82-point (p= 6.7 × 10−12) increase in a global deficit score. We replicated two SNPs (rs11634183 and rs12486041) with links to neural integrity. Patients in the top PRS quintile were at increased risk of cognitive impairment in discovery (RR = 1.95, 95%CI: 1.28–2.96, p= 0.002) and replication cohorts (OR = 1.84, 95%CI, 1.02–3.32, p= 0.043). Associations were stronger among individuals with lowest clinical risk for cognitive impairment. These findings support potential utility of PRS-based risk classification in the development of targeted interventions aimed at improving cognitive outcomes in BMT survivors.

We examine the impact of conditioning intensity (low intensity: nonmyeloablative/reduced intensity vs high intensity: myeloablative) and total body irradiation (TBI) on the probability of live birth after blood or marrow transplantation (BMT). Study participants were drawn from the BMT Survivor Study (BMTSS) and included 1607 transplant survivors between 1974 and 2014 at age ≤45 years, with survival ≥2 years post-BMT and age at study ≥18 years. Closest-age, same-sex biologic siblings (n = 172) were 1:1 matched with 172 survivors. Survivors and siblings self-reported information on sociodemographic, chronic health conditions, and pregnancies. Within survivor analysis: the association between the primary exposure variable (no TBI/low-intensity conditioning; 200 to 800 cGy TBI/low-intensity conditioning; no TBI/high-intensity conditioning; >800 cGy TBI/high-intensity conditioning) and the odds of no post-BMT live birth were examined using multivariable logistic regression, adjusting for clinical and demographic variables. Median age at BMT was 31 years (IQR, 0 to 45), and median length of follow-up was 14.3 years (IQR, 2.4 to 41.4); 39.3% were autologous BMT recipients, and 46.6% were female. Overall, 120 (8.7%) survivors reported post-BMT live births. Receipt of >800 cGy TBI/high-intensity conditioning (odds ratio [OR], 3.7; 95% CI, 1.9-7.0; ref: no TBI/low-intensity conditioning) was associated with higher odds of reporting no live birth post-BMT. In contrast, 200 to 800 cGy TBI/low-intensity conditioning (OR, 1.3; 95% CI, 0.5-3.3), and no TBI/high-intensity conditioning (OR, 0.9; 95% CI, 0.5-1.7) were at similar risk of reporting post-BMT live birth as no TBI/low-intensity conditioning. Comparison with biologic siblings: Using conditional logistic regression, we found that BMT survivors were more likely to report no live birth (OR, 2.0; 95% CI, 1.2-3.3) compared with siblings. These findings could inform conditioning intensity options for patients wishing to preserve fertility post-BMT.

Supplemental Digital Content is available in the text.Thiopurines [e.g. 6-mercaptopurine (6MP)] are essential for the cure of acute lymphoblastic leukemia (ALL) but can cause dose-limiting hematopoietic toxicity. Germline variants in drug-metabolizing enzyme genes TPMTand NUDT15have been linked to the risk of thiopurine toxicity. However, the full spectrum of genetic polymorphism in these genes and their impact on the pharmacological effects of thiopurines remain unclear. Herein, we comprehensively sequenced the TPMTand NUDT15genes in 685 children with ALL from the Children’s Oncology Group AALL03N1 trial and evaluated their association with 6MP dose intensity. We identified 6 and 5 coding variants in TPMTand NUDT15respectively, confirming the association at known pharmacogenetic variants. Importantly, we discovered a novel gain-of-function noncoding variants in TPMTassociated with increased 6MP tolerance (rs12199316), with independent validation in 380 patients from the St. Jude Total Therapy XV protocol. Located adjacent to a regulatory DNA element, this intergenic variant was strongly associated TPMTtranscription, with the variant allele linked to higher expression (P= 2.6 × 10−9). For NUDT15, one noncoding common variant, rs73189762, was identified as potentially related to 6MP intolerance. Collectively, we described pharmacogenetic variants in TPMTand NUDT15associated with thiopurine sensitivity, providing further insights for implementing pharmacogenetics-based thiopurine individualization.

Adolescents with Hodgkin lymphoma have worse disease outcomes than children. Whether these differences persist within clinical trials is unknown. We examined survival, by age, in patients receiving response-adapted therapy for Hodgkin lymphoma on Children's Oncology Group (COG) trials.

Adult survivors of childhood cancer have high rates of obesity, which, in combination with the cardiotoxic effects of specific cancer therapies, places them at high risk for cardiovascular morbidity. Here we show the contribution of genetic risk scores (GRSs) to increase prediction of those survivors of childhood cancer who are at risk for severe obesity (body mass index ≥40 kg m−2) as an adult. Among 2,548 individuals of European ancestry from the St. Jude Lifetime Cohort Study who were 5-year survivors of childhood cancer, the GRS was found to be associated with 53-fold-higher odds of severe obesity. Addition of GRSs to risk prediction models based on cancer treatment exposures and lifestyle factors significantly improved model prediction (area under the curve increased from 0.68 to 0.75, resulting in the identification of 4.3-times more high-risk survivors), which was independently validated in 6,064 individuals from the Childhood Cancer Survivor Study. Genetic predictors improve identification of patients who could benefit from heightened surveillance and interventions to mitigate the risk of severe obesity and associated cardio-metabolic complications.

The use of opioids and/or benzodiazepines in older adults (65 y+) who received an allogeneic hematopoietic cell transplant (HCT) is not known. In March 2016, the CDC released its strongest guidelines against prescription of opioids and co-prescription of opioids + benzodiazepines. We evaluated the use of opioids and/or benzodiazepines in older (65 y + , n= 114) vs. younger (40–64 y, n= 240) allogeneic-HCT recipients before and after the CDC guidelines. The proportion of patients with >10-days of use of opioids and/or benzodiazepines peri-HCT (day-14 to +28) was compared. Opioids:the older (65 + y) group had similar odds of receiving opioids as the younger group (40–64 y) [O.R. 0.7 (95%CI:0.4-1.2)]. Those transplanted after the CDC guideline had 0.4 (95%CI:0.2–0.7) times the odds of receiving opioids. Benzodiazepines:The older (65 + y) group was 0.6 times (95%CI:0.3–0.9) as likely to receive benzodiazepines. There was no significant change in benzodiazepines use after the CDC guideline. Opioids+ Benzodiazepines:The older group (65 + y) was 0.5 (95%CI:0.3–0.9) times as likely to receive both opioids+benzodiazepines. There was no significant change in opioids+benzodiazepines use after the CDC guideline. Though we observed a significant decrease in use of opioids after the CDC guideline, the use of benzodiazepines and combined opioids+benzodiazepines remained constant. Older recipients (65 + y) received less opioids, benzodiazepines, and combined opioids+benzodiazepines.

Patients undergoing allogeneic hematopoietic stem cell transplantation (allo-hsct) can require intensive care unit (ICU) admission in the post-transplant period. Whereas outcomes of ICU admission are poor, little is known about the pre-transplant risk factors leading to them. We conducted a retrospective analysis to investigate the impact of pre-transplant individual comorbidities on acute inpatient complications, focusing on ICU admission, ventilator support and multi-system organ failure, following allo-hsct. During the initial hospitalization, 33 (11%) patients required ICU admission, 29 (10%) required ventilator support and 33 (11%) developed multi-system organ failure. Risk factors for ICU admission and ventilator support included pre-transplant infection, pre-transplant diabetes, time to neutrophil engraftment, donor type and older transplant decade (2008-2010). Risk factors for multi-system organ failure included pre-transplant diabetes, time to neutrophil engraftment and older transplant decade (2008–2010). For ICU patients, the 60-day and 6-month mortality was 58% and 67%, respectively and the median overall survival was 1.4 months. Patients with diabetes and infection at the time of HSCT and longer time to neutrophil engraftment during transplant are at an increased risk for ICU admission, ventilator support and multi-system organ failure. Patients admitted to the ICU are also at a high risk for mortality leading to poor survival.

IMPORTANCE: The past 4 decades have seen substantial changes in allogeneic blood or marrow transplantation (BMT) practice, with the overarching goal of expanding the eligible patient pool while optimizing disease-free survival. OBJECTIVE: To determine trends in life expectancy and cause-specific late mortality after allogeneic BMT performed over a 40-year period. DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort study of 4741 individuals who lived 2 or more years after allogeneic BMT performed between January 1, 1974, and December 31, 2014, was conducted at City of Hope, University of Minnesota, or University of Alabama at Birmingham. The end of follow-up was March 23, 2020. EXPOSURES: Allogeneic BMT performed in 3 eras: 1974-1989, 1990-2004, and 2005-2014. MAIN OUTCOMES AND MEASURES: All-cause, recurrence-related, and nonrecurrence-related mortality and projected reduction in life expectancy. Information regarding vital status and cause of death was obtained from the National Death Index Plus and Accurint databases. RESULTS: Of the 4741 individuals included in the study, 2735 (57.7%) were male; median age at BMT was 33 years (range, 0-75 years). The cumulative incidence of recurrence-related mortality plateaued at 10 years, reaching 12.2% (95% CI, 11.0%-13.4%) at 30 years from BMT. In contrast, the incidence of nonrecurrence-related mortality continued to increase and was 22.3% (95% CI, 20.4%-24.3%) at 30 years. Leading causes of nonrecurrence-related mortality included infection (30-year cumulative incidence, 10.7%; standardized mortality ratio [SMR], 52.0), subsequent malignant neoplasms (30-year cumulative incidence, 7.0%; SMR, 4.8), cardiovascular disease (30-year cumulative incidence, 4.6%; SMR, 4.1), and pulmonary disease (30-year cumulative incidence, 2.7%; SMR, 13.9). Compared with the general population, the relative mortality remained higher at 30 or more years after BMT (SMR, 5.4; 95% CI, 4.0-7.1). The cohort experienced a 20.8% reduction in life expectancy (8.7 years of life lost). Compared with 1974-1989 (reference), the adjusted 10-year hazard ratio (HR) of all-cause mortality declined over the 3 eras (1990-2004: HR, 0.67; 95% CI, 0.53-0.85; 2005-2014: HR, 0.52; 95% CI, 0.39-0.69; P &lt; .001 for trend), as did years of life lost (1974-1989: 9.9 years [reference]; 1990-2004: 6.5 years; and 2005-2014: 4.2 years). The reduction in late mortality was most pronounced among individuals who underwent transplantation at ages younger than 18 years (1990-2004: HR, 0.62; 95% CI, 0.40-0.96; 2005-2014: HR, 0.30; 95% CI, 0.16-0.54; reference: 1974-1989; P &lt; .001 for trend) and those who received bone marrow (1990-2004: HR, 0.70; 95% CI, 0.54-0.90; 2005-2014: HR, 0.45; 95% CI, 0.29-0.69; reference: 1974-1989; P &lt; .001 for trend). CONCLUSIONS AND RELEVANCE: This cohort study noted that late mortality among recipients of allogeneic BMT has decreased over the past 40 years; however, life expectancy was not restored to expected rates compared with the general US population. Furthermore, the reduction in risk of late mortality appeared to be confined to those who underwent transplantation at a younger age or those who received bone marrow. Further efforts to mitigate disease recurrence, infections, subsequent neoplasms, cardiovascular disease, and pulmonary disease may be useful in this population.

Allogeneic blood or marrow transplant (BMT) recipients are at risk for venous thromboembolism (VTE) because of high-intensity therapeutic exposures, comorbidities, and a proinflammatory state due to chronic graft-versus-host disease (GVHD). The long-term risk of VTE in allogeneic BMT survivors remains unstudied. Participants were drawn from the Blood or Marrow Transplant Survivor Study (BMTSS), a retrospective cohort study that included patients who underwent transplantation between 1974 and 2014 and survived ≥2 years after BMT. We analyzed the risk of VTE in 1554 2-year survivors of allogeneic BMT compared with 907 siblings. Using backward variable selection guided by minimizing Akaike information criterion, we created a prediction model for risk of late-occurring VTE. Allogeneic BMT survivors had a 7.3-fold higher risk of VTE compared with siblings (95% CI, 4.69-11.46; P < .0001). After a median follow-up of 11 years, conditional on surviving the first 2 years after BMT, the cumulative incidence of late-occurring VTE was 2.4% at 5 years, 4.9% at 10 years, and 7.1% at 20 years after BMT. The final model for VTE risk at 2 years post-BMT included History of stroke, chronic GVHD, Hypertension, Sex (male vs female) and Stem cell source (peripheral blood stem cells vs other) (“HiGHS2”) (corrected C-statistics: 0.73; 95% CI = 0.67-0.79). This model was able to classify patients at high and low VTE risk (10-year cumulative incidence, 9.3% vs 2.4% respectively; P < .0001). The BMTSS HiGHS2 risk model when applied at 2 years post-BMT can be used to inform targeted prevention strategies for patients at high risk for late-occurring VTE.

Therapeutic practices for multiple myeloma (MM) have evolved, such that novel-agent–based therapy and autologous peripheral blood stem cell transplantation (aPBSCT) is the current standard. Whether cause-specific mortality has changed with time remains unclear. We examined late cause-specific mortality among patients with MM receiving aPBSCT from 1989 to 2014. We conducted a prospective cohort study using participants enrolled in the enrolled in the Blood or Marrow Transplant Survivor Study. We created 3 eras to reflect changing MM therapy: <2000 (pre-thalidomide); 2000-2005 (thalidomide); 2006-2014 (lenalidomide). We used Kaplan-Meier techniques and Cox regression for examining all-cause mortality, and subdistribution hazards models for cause-specific mortality. In total, 1906 patients were followed up for a median of 9.2 years. Conditional on surviving 2 years, the 10-year overall survival was 45%. The 10-year cumulative incidence of myeloma- and non-myeloma-related mortality was 33% and 13%, respectively. Multivariable analysis showed declining MM-specific mortality (subdistribution hazard ratio [SHR]2000-2005 = 0.80, 95% confidence interval [CI], 0.60-1.07; SHR2006-2014 = 0.46, 95% CI, 0.34-0.62; referent group: <2000), infection-related mortality (SHR2000-2005 = 0.50, 95% CI, 0.29-0.85; SHR2006-2014 = 0.35, 95%CI 0.21-0.60; referent group: <2000) and cardiovascular disease-related mortality (SHR2000-2005 = 0.45, 95% CI 0.20-0.99; SHR2006-2014 = 0.41, 95% CI 0.18-0.93; referent group: <2000). Although primary disease remains the major cause of late mortality, we observed a significant temporal decline in myeloma-, infection-, and cardiac-related late mortality over the past 25 years.

Mortality is highest in the first year following an allogeneic hematopoietic stem cell transplant. With recent advancements, we have expanded the pool of patients to whom we are able to offer transplant as a treatment option. In this context, we analyzed socioeconomic, patient, disease and transplant-related variables that predicted for 1-year all-cause, relapse-related (RRM) and non-relapse related mortality (NRM) in 304 patients at the University of Alabama at Birmingham. The 1-year overall survival, RRM and NRM rates were 60.5%, 13.5% and 22.7% respectively. A KPS score < 80, pre-transplant infection and hypertension and non-complete remission disease status adversely effected all-cause mortality. For NRM, increasing age, pre-transplant infection and diabetes, and poor access to care were associated with higher mortality whereas haploidentical donor type was associated with improved survival. For RRM, a KPS score <80, high/very high disease risk index and the presence of comorbidities were risk factors for higher mortality. Poor access to care, in addition to individual comorbidities, performance status and high-risk disease characteristics, is associated with adverse outcomes following transplant. We propose the incorporation of socioeconomic variables with patient, disease, and transplant-related variables to predict 1-year NRM.

There is a growing population of children with complex chronic conditions (CCCs) whose caregivers would benefit from palliative care (PC). However, little is known about caregivers' PC awareness. We aimed to describe PC awareness among caregivers of children with CCCs and identify factors associated with lack of PC awareness. We used the National Cancer Institute's national Health Information National Trends Survey 2018 data to determine the percentage of caregivers of ill children who have PC awareness. After matching, caregiver PC awareness was compared with that of (1) the general survey population, (2) other caregivers, and (3) caregivers not caring for children. We used multivariable regression to determine factors associated with lack of PC awareness. Of 131 caregivers, 60% had “never heard of” PC. Caregivers of children were no more likely to have heard of PC than the general survey population (P= .76), noncaregivers (P= .97), or caregivers of nonchildren (P= .13). Caregivers younger than 40 years and without a college degree were less likely to have PC awareness than their peers. Most caregivers of ill children have no PC awareness, with no more PC awareness than the general population. Nurses caring for children with CCCs can help educate families and other health care team members about PC.

The authors’ objective is to provide a brief update on recent advances in knowledge relating to subsequent primary neoplasms developing in survivors of childhood cancer. This includes a summary of established large-scale cohorts, risks reported, and contrasts with results from recently established large-scale cohorts of survivors of adolescent and young adult cancer. Recent evidence is summarized concerning the role of radiotherapy and chemotherapy for childhood cancer and survivor genomics in determining the risk of subsequent primary neoplasms. Progress with surveillance, screening, and clinical follow-up guidelines is addressed. Finally, priorities for future research are outlined.

IMPORTANCE: Osteosarcoma, the most common malignant bone tumor in children and adolescents, occurs in a high number of cancer predisposition syndromes that are defined by highly penetrant germline mutations. The germline genetic susceptibility to osteosarcoma outside of familial cancer syndromes remains unclear. OBJECTIVE: To investigate the germline genetic architecture of 1244 patients with osteosarcoma. DESIGN, SETTING, AND PARTICIPANTS: Whole-exome sequencing (n = 1104) or targeted sequencing (n = 140) of the DNA of 1244 patients with osteosarcoma from 10 participating international centers or studies was conducted from April 21, 2014, to September 1, 2017. The results were compared with the DNA of 1062 individuals without cancer assembled internally from 4 participating studies who underwent comparable whole-exome sequencing and 27 173 individuals of non-Finnish European ancestry who were identified through the Exome Aggregation Consortium (ExAC) database. In the analysis, 238 high-interest cancer-susceptibility genes were assessed followed by testing of the mutational burden across 736 additional candidate genes. Principal component analyses were used to identify 732 European patients with osteosarcoma and 994 European individuals without cancer, with outliers removed for patient-control group comparisons. Patients were subsequently compared with individuals in the ExAC group. All data were analyzed from June 1, 2017, to July 1, 2019. MAIN OUTCOMES AND MEASURES: The frequency of rare pathogenic or likely pathogenic genetic variants. RESULTS: Among 1244 patients with osteosarcoma (mean [SD] age at diagnosis, 16 [8.9] years [range, 2-80 years]; 684 patients [55.0%] were male), an analysis restricted to individuals with European ancestry indicated a significantly higher pathogenic or likely pathogenic variant burden in 238 high-interest cancer-susceptibility genes among patients with osteosarcoma compared with the control group (732 vs 994, respectively; P = 1.3 × 10−18). A pathogenic or likely pathogenic cancer-susceptibility gene variant was identified in 281 of 1004 patients with osteosarcoma (28.0%), of which nearly three-quarters had a variant that mapped to an autosomal-dominant gene or a known osteosarcoma-associated cancer predisposition syndrome gene. The frequency of a pathogenic or likely pathogenic cancer-susceptibility gene variant was 128 of 1062 individuals (12.1%) in the control group and 2527 of 27 173 individuals (9.3%) in the ExAC group. A higher than expected frequency of pathogenic or likely pathogenic variants was observed in genes not previously linked to osteosarcoma (eg, CDKN2A, MEN1, VHL, POT1, APC, MSH2, and ATRX) and in the Li-Fraumeni syndrome-associated gene, TP53. CONCLUSIONS AND RELEVANCE: In this study, approximately one-fourth of patients with osteosarcoma unselected for family history had a highly penetrant germline mutation requiring additional follow-up analysis and possible genetic counseling with cascade testing.

IMPORTANCE: Imatinib introduced a paradigm shift in the treatment of patients with chronic myeloid leukemia (CML), allowing a lifespan that is almost comparable to the general population. However, the health care expenditures associated with imatinib have increased steadily since its introduction in 2001. Since the generic market entry of imatinib on February 1, 2016, it became possible to determine the effect of generic entry on the health care expenditures associated with imatinib, along with the concurrent pricing trends of second-generation tyrosine kinase inhibitors (TKIs). OBJECTIVE: To compare health care expenditure related to imatinib treatment for patients with CML prior to its generic status with expenditures after, in a real-world setting. DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort study using data from the Truven Health MarketScan Database was carried out including 1301 commercially insured patients or patients with Medicaid between the ages of 18 and 64 years with a CML diagnosis between September 1, 2014 and December 31, 2017. A single interrupted time series (ITS) method was used to evaluate monthly expenditures associated with imatinib for the health plan from September 1, 2014 to December 31, 2017, with imatinib switching to generic on February 1, 2016, as the interruption. The initial 6-month period postinterruption was excluded to allow for the new price structure to stabilize. Nilotinib and dasatinib were evaluated using a comparative ITS design. The analysis took place between September 1, 2014 to December 31, 2017. MAIN OUTCOMES AND MEASURES: Commercial and Medicaid health plan expenditure and patient cost responsibility for 30-day blocks per patient for imatinib, dasatinib, and nilotinib were calculated from September 1, 2014 through December 31, 2017. Pricing was adjusted via 2017 consumer price index for medical services. RESULTS: The sample included a total of 1301 patients (1102 commercially insured and 199 insured through Medicaid) with a median (range) age at diagnosis of 50 (18-62) years for commercially insured patients and 50 (47-52) years for patients with Medicaid. Of the 1301 patients, 704 (54.1%) were men. There was a significant pregeneric increase in expenditure (commercially insured: $143 per patient per month, P &lt; .001; Medicaid: $152 per patient per month, P = .001). There was a significant reduction over the 6-month interruption period (February 2016 through August 2016) between the pregeneric and generic phase (commercial: $−3097 per patient, P &lt; .001; Medicaid: $−2077 per patient, P = .002). Controlling for secular trends, this was followed by a small decline in expenditure during the generic phase (commercially insured: −$93 per patient per month; P = .03; Medicaid: −$182 per patient per month; P = .001). Nilotinib and dasatinib maintained an increasing trend in both the pregeneric and generic phase of imatinib, resulting in a significant difference-in-difference slope for commercially insured patients (nilotinib: −$186, P = .006; dasatinib: −$175, P = .007) and patients with Medicaid (nilotinib: −$299, P = .002; dasatinib: −$329, P &lt; .001). There were no significant trends for patient cost responsibility. CONCLUSIONS AND RELEVANCE: The modest decline in expenditure associated with imatinib after generic entry accompanied by the increasing expenditure trends associated with the second-generation TKIs suggest a need for measures to facilitate cost reduction as well as standardization of CML treatment.

The most interesting and novel finding in this study is that although many patients were followed with CT scans for their primary disease, few recurrences were identified or managed with [...]
