RESUMEN

Diversity in the genetic lesions that cause cancer is extreme. In consequence, a pressing challenge is the development of drugs that target patient-specific disease mechanisms. To address this challenge, we employed a chemistry-first discovery paradigm for de novo identification of druggable targets linked to robust patient selection hypotheses. In particular, a 200,000 compound diversity-oriented chemical library was profiled across a heavily annotated test-bed of >100 cellular models representative of the diverse and characteristic somatic lesions for lung cancer. This approach led to the delineation of 171 chemical-genetic associations, shedding light on the targetability of mechanistic vulnerabilities corresponding to a range of oncogenotypes present in patient populations lacking effective therapy. Chemically addressable addictions to ciliogenesis in TTC21B mutants and GLUT8-dependent serine biosynthesis in KRAS/KEAP1 double mutants are prominent examples. These observations indicate a wealth of actionable opportunities within the complex molecular etiology of cancer.

RESUMEN

Approximately one-half of individuals with cancer face personal economic burdens associated with the disease and its treatment, a problem known as financial toxicity (FT). FT more frequently affects socioeconomically vulnerable individuals and leads to subsequent adverse economic and health outcomes. Whereas multilevel systemic factors at the policy, payer, and provider levels drive FT, there are also accompanying intervenable patient-level factors that exacerbate FT in the setting of clinical care delivery. The primary strategy to intervene on FT at the patient level is financial navigation. Financial navigation uses comprehensive assessment of patients' risk factors for FT, guidance toward support resources, and referrals to assist patient financial needs during cancer care. Social workers or nurse navigators most frequently lead financial navigation. Oncologists and clinical provider teams are multidisciplinary partners who can support optimal FT management in the context of their clinical roles. Oncologists and clinical provider teams can proactively assess patient concerns about the financial hardship and employment effects of disease and treatment. They can respond by streamlining clinical treatment and care delivery planning and incorporating FT concerns into comprehensive goals of care discussions and coordinated symptom and psychosocial care. By understanding how age and life stage, socioeconomic, and cultural factors modify FT trajectory, oncologists and multidisciplinary health care teams can be engaged and informative in patient-centered, tailored FT management. The case presentations in this report provide a practical context to summarize authors' recommendations for patient-level FT management, supported by a review of key supporting evidence and a discussion of challenges to mitigating FT in oncology care.

RESUMEN

Context-specific molecular vulnerabilities that arise during tumor evolution represent an attractive intervention target class. However, the frequency and diversity of somatic lesions detected among lung tumors can confound efforts to identify these targets. To confront this challenge, we have applied parallel screening of chemical and genetic perturbations within a panel of molecularly annotated NSCLC lines to identify intervention opportunities tightly linked to molecular response indicators predictive of target sensitivity. Anchoring this analysis on a matched tumor/normal cell model from a lung adenocarcinoma patient identified three distinct target/response-indicator pairings that are represented with significant frequencies (6%-16%) in the patient population. These include NLRP3 mutation/inflammasome activation-dependent FLIP addiction, co-occurring KRAS and LKB1 mutation-driven COPI addiction, and selective sensitivity to a synthetic indolotriazine that is specified by a seven-gene expression signature. Target efficacies were validated in vivo, and mechanism-of-action studies informed generalizable principles underpinning cancer cell biology.

RESUMEN

BACKGROUND: Polyclonal convalescent plasma may be obtained from donors who have recovered from coronavirus disease 2019 (Covid-19). The efficacy of this plasma in preventing serious complications in outpatients with recent-onset Covid-19 is uncertain. METHODS: In this multicenter, double-blind, randomized, controlled trial, we evaluated the efficacy and safety of Covid-19 convalescent plasma, as compared with control plasma, in symptomatic adults (≥18 years of age) who had tested positive for severe acute respiratory syndrome coronavirus 2, regardless of their risk factors for disease progression or vaccination status. Participants were enrolled within 8 days after symptom onset and received a transfusion within 1 day after randomization. The primary outcome was Covid-19-related hospitalization within 28 days after transfusion. RESULTS: Participants were enrolled from June 3, 2020, through October 1, 2021. A total of 1225 participants underwent randomization, and 1181 received a transfusion. In the prespecified modified intention-to-treat analysis that included only participants who received a transfusion, the primary outcome occurred in 17 of 592 participants (2.9%) who received convalescent plasma and 37 of 589 participants (6.3%) who received control plasma (absolute risk reduction, 3.4 percentage points; 95% confidence interval, 1.0 to 5.8; P = 0.005), which corresponded to a relative risk reduction of 54%. Evidence of efficacy in vaccinated participants cannot be inferred from these data because 53 of the 54 participants with Covid-19 who were hospitalized were unvaccinated and 1 participant was partially vaccinated. A total of 16 grade 3 or 4 adverse events (7 in the convalescent-plasma group and 9 in the control-plasma group) occurred in participants who were not hospitalized. CONCLUSIONS: In participants with Covid-19, most of whom were unvaccinated, the administration of convalescent plasma within 9 days after the onset of symptoms reduced the risk of disease progression leading to hospitalization.

RESUMEN

How hematopoietic stem cells (HSCs) coordinate the regulation of opposing cellular mechanisms such as self-renewal and differentiation commitment remains unclear. Here we identified the transcription factor and chromatin remodeler Satb1 as a critical regulator of HSC fate. HSCs lacking Satb1 had defective self-renewal, were less quiescent and showed accelerated lineage commitment, which resulted in progressive depletion of functional HSCs. The enhanced commitment was caused by less symmetric self-renewal and more symmetric differentiation divisions of Satb1-deficient HSCs. Satb1 simultaneously repressed sets of genes encoding molecules involved in HSC activation and cellular polarity, including Numb and Myc, which encode two key factors for the specification of stem-cell fate. Thus, Satb1 is a regulator that promotes HSC quiescence and represses lineage commitment.

RESUMEN

BACKGROUND: In the general population, individuals with minoritized sexual orientation and gender identity have a higher burden of chronic health conditions than heterosexual individuals. However, the extent to which sexual orientation is associated with excess burden of chronic conditions in adolescent and young adult cancer survivors (AYACS) is unknown. METHODS: Lesbian, gay, and bisexual (LGB) AYACSs, LGB individuals without a history of cancer, and heterosexual AYACSs were identified by self-reported data from the cross-sectional National Health Interview Survey (2013-2020). Socioeconomic factors and the prevalence of chronic health conditions were compared between groups using χ2 tests. Logistic regression methods were used to determine the odds of chronic conditions by socioeconomic factors within and between survivor and comparison groups. RESULTS: One hundred seventy LGB cancer survivors, 1700 LGB individuals without a history of cancer, and 1700 heterosexual cancer survivors were included. Compared with heterosexual survivors, LGB survivors were less likely to be married (p = .001) and more likely to have never been married (p < .001). LGB survivors were more likely to have incomes between 100% and 200% of the federal poverty level than LGB individuals without a history of cancer (p = .012) and heterosexual survivors (p = .021) and were less likely to report incomes >200% the federal poverty level. LGB survivors had higher odds of chronic health conditions than LGB individuals without a history of cancer (odds ratio, 2.45; p < .001) and heterosexual survivors (odds ratio, 2.16; p = .003). CONCLUSIONS: LGB AYACSs are at increased risk of having chronic health conditions compared with both LGB individuals without a history of cancer and heterosexual AYACSs.

RESUMEN

INTRODUCTION: Fertility after cancer is a top concern for adolescents and young adults with cancer (AYAs) (15-39 years old at diagnosis). The authors characterized live births after cancer by race and ethnicity ("race/ethnicity") in a population-based sample of female AYAs. METHODS: This study used Texas Cancer Registry data linked to birth certificates (1995-2016) to estimate cumulative incidence of live birth, based on first live birth after cancer, and compared differences by race/ethnicity. Proportional subdistribution hazards models were used to estimate associations between race/ethnicity and live birth, adjusted for diagnosis age, cancer type, stage, year, and prior live birth, overall and for each cancer type. RESULTS: Among 65,804 AYAs, 10-year cumulative incidence of live birth was lower among non-Hispanic Black AYAs than other racial/ethnic groups: 10.2% (95% confidence interval [CI], 9.4-10.9) compared to 15.9% (95% CI, 14.1-17.9) among Asian or Pacific Islander, 14.7% (95% CI, 14.2-15.3) among Hispanic, and 15.2% (95% CI, 14.8-15.6) among non-Hispanic White AYAs (p < .01). In the adjusted overall model, Black AYAs were less likely to have a live birth after cancer than all other groups. In adjusted models for each cancer type, live birth was significantly less likely for Black AYAs with gynecologic cancers or lymphomas (compared to White AYAs) or thyroid cancers (compared to Hispanic AYAs). CONCLUSION: Black AYAs are less likely than AYAs of other races/ethnicities to have a live birth after cancer, in contrast to patterns of live birth in the general population. Research and action to promote childbearing equity after cancer are imperative.

RESUMEN

BACKGROUND: Survivors of adolescent and young adult (AYA) cancer experience significant psychological distress and encounter barriers to accessing mental health care. Few studies have investigated racial/ethnic disparities in psychological health outcomes among AYA survivors, and none have compared outcomes within a racially minoritized population. METHODS: National Health Interview Survey data (2010-2018) were analyzed that identified non-Hispanic Black (hereafter, Black) survivors of AYA cancer and age- and sex-matched Black noncancer controls. Sociodemographic factors, chronic health conditions, modifiable behaviors (smoking and alcohol use), and psychological outcomes were assessed with χ2 tests. Logistic regression models, adjusted for survey weights, were used to evaluate the odds of psychological distress by cancer status after adjusting for covariates. Interactions between variables and cancer status were investigated. RESULTS: The study included 334 Black survivors of AYA cancer and 3340 Black controls. Compared to controls, survivors were more likely to report moderate/severe distress (odds ratio [OR], 1.64; p < .001), use mental health care (OR, 1.53; p = .027), report an inability to afford mental health care (OR, 3.82; p < .001), and use medication for anxiety and/or depression (OR, 2.16; p = .001). Forty-one percent of survivors reported moderate/severe distress, and only 15% used mental health care. Among survivors, ages 18-39 years (vs. 40-64 years) and current smoking (vs. never smoking) were associated with the presence of moderate/severe distress. Among survivors with distress, high poverty status was associated with reduced utilization of mental health care. CONCLUSIONS: A cancer diagnosis for a Black AYA is associated with greater psychological distress within an already vulnerable population.

RESUMEN

There is a known genetic susceptibility to anthracycline-induced cardiac dysfunction in childhood cancer survivors, but this has not been adequately shown in adolescent and young adult (AYA) patients. Our aim was to determine if the previously identified variants associated with cardiac dysfunction in childhood cancer patients affect AYA cancer patients similarly. Forty-five variants were selected for analysis in 253 AYAs previously treated with anthracyclines. We identified four variants that were associated with cardiac dysfunction: SLC10A2:rs7319981 (p = 0.017), SLC22A17:rs4982753 (p = 0.019), HAS3:rs2232228 (p = 0.023), and RARG:rs2229774 (p = 0.050). HAS3:rs2232228 and SLC10A2:rs7319981 displayed significant effects in our AYA cancer survivor population that were in the opposite direction than that reported in childhood cancer survivors. Genetic variants in the host genes were further analyzed for additional associations with cardiotoxicity in AYA cancer survivors. The host genes were then evaluated in a panel of induced pluripotent stem cell-derived cardiomyocytes to assess changes in levels of expression when treated with doxorubicin. Significant upregulation of HAS3 and SLC22A17 expression was observed (p < 0.05), with non-significant anthracycline-responsivity observed for RARG. Our study demonstrates that there is a genetic influence on cardiac dysfunction in AYA cancer patients, but there may be a difference in the role of genetics between childhood and AYA cancer survivors.

RESUMEN

BACKGROUND: Steroid insensitivity in Chronic Obstructive Pulmonary Disease (COPD) presents a problem for controlling the chronic inflammation of the airways. The glucocorticoid receptor (GR) mediates the intracellular signaling of inhaled corticosteroids (ICS) by interacting with transcription factors and histone deacetylases (HDACs). The aim of this study was to assess if COPD patients' response to ICS in vivo, may be associated with the expression of GR, the complex of GR with transcription factors, and the expression of various HDACs in vitro. METHODS: Primary airway smooth muscle cells (ASMC) were established from endobronchial biopsies obtained from patients with asthma (n = 10), patients with COPD (n = 10) and subjects that underwent diagnostic bronchoscopy without pathological findings and served as controls (n = 6). ASMC were also established from 18 COPD patients, 10 responders and 8 non-responders to ICS, who participated in the HISTORIC study, an investigator-initiated and driven clinical trial that proved the hypothesis that COPD patients with high ASMC in their endobronchial biopsies respond better to ICS than patients with low ASMC. Expression of GR and its isoforms GRα and GRß and HDACs was investigated in primary ASMC in the absence or in the presence of dexamethasone (10- 8M) by western blotting. The complex formation of GR with transcription factors was assessed by co-immunoprecipitation. RESULTS: Expression of GR and its isoform GRα but not GRß was significantly reduced in ASMC from COPD patients as compared to controls. There were no significant differences in the expression of GR, GRα and GRß between responders and non-responders to ICS. However, treatment with dexamethasone upregulated the expression of total GR (p = 0.004) and GRα (p = 0.005) after 30 min in responders but not in non-responders. Τhe formation of the complex GR-c-Jun was increased 60 min after treatment with dexamethasone only in responders who exhibited significantly lower expression of HDAC3 (p = 0.005) and HDAC5 (p < 0.0001) as compared to non-responders. CONCLUSIONS: These data suggest that ASMC from COPD patients who do not respond to treatment with ICS, are characterized by reduced GR-c-Jun complex formation and increased expression of HDAC3 and HDAC5.

RESUMEN

PURPOSE: The response to glucocorticoids is hampered in many COPD patients by a yet unknown mechanism. Earlier we reported that short-term heat exposure of primary human bronchial epithelial cells (BEC) and airway smooth muscle cells (ASMC) of asthma patients increased the expression and secretion of extracellular heat shock proteins (eHSPs) resulting in increased expression of glucocorticoid receptor (GR) in BEC and inhibition of ASMC remodeling. The aim of the present study was to assess if the same mechanism is also present in primary airway wall cells of COPD patients. METHODS: Primary BEC and ASMC were established from endobronchial biopsies obtained from COPD patients (n = 73), who participated in the HISTORIC study, an investigator-initiated and driven clinical trial. Secretion and protein expression of HSPs was assessed by ELISA and Western blotting. Expression of total GR, its isoforms GRα and GRß and toll-like receptor 4 (TLR4) was determined by Western-blotting. RESULTS: Short heat exposure (65 °C, 10 s) of BEC resulted in a significant increase of the secretion of eHSP70 and eHSP90, while the intracellular protein was not altered. Heat treatment or exposure to eHSP70 or eHSP90 had no effect on the expression of GR and GR-isoforms. However, eHSP70 and eHSP90 significantly reduced the expression of TLR4. CONCLUSIONS: The results of this study indicate that primary airway cells from COPD patients respond differently to heat exposure and extracellular HSP70 or HSP90 than cells from asthma patients regarding the expression of GR and this may explain the reduced response to glucocorticoids in patients with COPD. TRIAL REGISTRATION: ISRCTN11017699.

RESUMEN

Anthracyclines are effective chemotherapeutics used in approximately 60% of pediatric cancer cases but have a well-documented risk of cardiotoxicity. Existing cardiotoxicity risk calculators do not include cardiovascular risk factors present at the time of diagnosis. The goal of this study is to leverage the advanced sensitivity of strain echocardiography to identify pre-existing risk factors for early subclinical cardiac dysfunction among anthracycline-exposed pediatric patients. We identified 115 pediatric patients with cancer who were treated with an anthracycline between 2013 and 2019. Peak longitudinal left ventricular strain was retroactively calculated on 495 surveillance echocardiograms via the TOMTEC AutoSTRAIN software. Cox proportional hazards models were employed to identify risk factors for abnormal longitudinal strain (> - 16%) following anthracycline treatment. High anthracycline dose (≥ 250 mg/m2 doxorubicin equivalents) and obesity at the time of diagnosis (BMI > 95th percentile-for-age) were both significant predictors of abnormal strain with hazard ratios of 2.79, 95% CI (1.07-7.25), and 3.85, 95% CI (1.42-10.48), respectively. Among pediatric cancer survivors, patients who are obese at the time of diagnosis are at an increased risk of sub-clinical cardiac dysfunction following anthracycline exposure. Future studies should explore the incidence of symptomatic cardiomyopathy 10-15 years post-treatment among patients with early subclinical cardiac dysfunction.

RESUMEN

BACKGROUND: There is a growing population of adolescent and young adult (AYA) cancer survivors (ages 15-39 years), and they have an elevated risk of developing cardiovascular disease (CVD). Little is known about the contribution of sociodemographic and modifiable factors to the risk of CVD in AYA survivors and whether these factors differentially modulate their risk compared with that in the general population. The current study sought to fill these gaps. METHODS: Self-reported data from the US National Health Interview Survey (2009-2018) were used to identify AYA cancer survivors (≥2 years postdiagnosis) and age-matched and sex-matched controls. The risk of CVD based on sociodemographic factors (sex, race/ethnicity, income, education) and modifiable risk factors (diabetes, body mass index, smoking, physical activity) was determined within and between survivors and controls using logistic regression models. RESULTS: In total, 4766 AYA cancer survivors and 47,660 controls were included. The odds of CVD were significantly higher in survivors than in controls by sex, race/ethnicity, income, education, smoking status, and physical activity. An annual household income <$50,000 disproportionately increased the odds of CVD in survivors. One third of survivors reported no moderate-to-vigorous-intensity physical activity (MVPA). Performing any MVPA lowered the odds of CVD in survivors (odds ratio, 0.61; 95% CI, 0.450.81) and controls (odds ratio, 0.68; 95% CI, 0.61-0.77). CONCLUSIONS: Sociodemographic and modifiable risk factors increased the odds of CVD in AYA survivors, in some cases disproportionately, compared with controls. Understanding health behavior trajectories among different sociodemographic populations is needed to identify opportunities to lower the risk of CVD. Performing any MVPA is particularly important for AYA survivors.

RESUMEN

BACKGROUND: The increasing number of childhood cancer survivors necessitates continued follow-up to monitor for long-term complications. Inequities in loss to follow-up for patients enrolled on pediatric clinical trials have not been well studied. METHODS: This was a retrospective study of 21,084 patients residing in the United States enrolled on phase 2/3 and phase 3 Children's Oncology Group (COG) trials between January 1, 2000 and March 31, 2021. Rates of loss to follow-up to COG were evaluated using log-rank tests and multivariable Cox proportional hazards regression models with adjusted hazard ratios (HRs). Demographic characteristics included age at enrollment, race, ethnicity, and zip code level socioeconomic data. RESULTS: Adolescent and young adult (AYA) patients 15-39 years old at diagnosis had an increased hazard of loss to follow-up compared to patients 0-14 years old (HR, 1.89; 95% confidence interval (CI), 1.76-2.02). In the overall cohort, non-Hispanic Blacks were found to have an increased hazard of loss to follow-up compared to non-Hispanic Whites (HR, 1.56; 95% CI, 1.43-1.70). Among AYAs, the highest loss to follow-up rates were among non-Hispanic Blacks (69.8% ± 3.1%), patients on germ cell tumor trials (78.2% ± 9.2%), and patients living in zip codes with a median household income ≤150% of the federal poverty line at diagnosis (66.7% ± 2.4%). CONCLUSIONS: AYAs, racial and ethnic minority patients, and those living in lower socioeconomic status areas had the highest rates of loss to follow-up among clinical trial participants. Targeted interventions are warranted to ensure equitable follow-up and improved assessment of long-term outcomes. PLAIN LANGUAGE SUMMARY: Little is known about disparities in loss to follow-up for pediatric cancer clinical trial participants. In this study, we found that participants who were adolescents and young adults when treated, those who identified as a racial and/or ethnic minority, or those residing in areas with lower socioeconomic status at diagnosis were associated with higher rates of loss to follow-up. As a result, the ability to assess their long-term survival, treatment-related health conditions, and quality of life is hindered. These findings suggest the need for targeted interventions to improve long-term follow-up among disadvantaged pediatric clinical trial participants.

RESUMEN

BACKGROUND: There is substantial heterogeneity in symptom management provided to pediatric patients with cancer. The primary objective was to describe the adaptation process and specific adaptation decisions related to symptom management care pathways based on clinical practice guidelines. The secondary objective evaluated if institutional factors were associated with adaptation decisions. METHODS: Fourteen previously developed symptom management care pathway templates were reviewed by an institutional adaptation team composed of two clinicians at each of 10 institutions. They worked through each statement for all care pathway templates sequentially. The institutional adaptation team made the decision to adopt, adapt or reject each statement, resulting in institution-specific symptom management care pathway drafts. Institutional adaption teams distributed the 14 care pathway drafts to their respective teams; their feedback led to care pathway modifications. RESULTS: Initial care pathway adaptation decision making was completed over a median of 4.2 (interquartile range 2.0-5.3) weeks per institution. Across all institutions and among 1350 statements, 551 (40.8%) were adopted, 657 (48.7%) were adapted, 86 (6.4%) were rejected and 56 (4.1%) were no longer applicable because of a previous decision. Most commonly, the reason for rejection was not agreeing with the statement (70/86, 81.4%). Institutional-level factors were not significantly associated with statement rejection. CONCLUSIONS: Acceptability of the 14 care pathways was evident by most statements being adopted or adapted. The adaptation process was accomplished over a relatively short timeframe. Future work should focus on evaluation of care pathway compliance and determination of the impact of care pathway-consistent care on patient outcomes.

RESUMEN

PURPOSE: Survivors of adolescent and young adult (AYA) cancer experience psychological distress and insufficient access to mental health care. Few studies have investigated racial/ethnic disparities in psychological health outcomes in this population. This study compared psychological distress, mental health care use, and inability to afford mental health care between Hispanic/Latino survivors of AYA cancer and Hispanic/Latino controls. METHODS: The National Health Interview Survey data (2010-2018) were analyzed to identify Hispanic/Latino survivors of AYA cancer and Hispanic/Latino age- and sex-matched non-cancer controls. Sociodemographic, chronic health, modifiable factors, and psychological outcomes were compared using chi-square tests. Logistic regression models with survey weights were used to assess the log-odds of psychological distress in relation to covariates, along with the cancer group. Interactions were evaluated between each variable and cancer group. RESULTS: The study included 370 Hispanic/Latino survivors of AYA cancer (mean time since diagnosis = 12.34 years) and 3700 Hispanic/Latino controls. Compared to controls, survivors were more likely to report moderate/severe distress (OR = 2.23, p < 0.001), use of mental health care (OR = 2.11, p < 0.001) and inability to afford mental health care (OR = 3.05, p < 0.001). Forty-one percent of survivors reported moderate/severe distress and only 16% utilized mental health care. Among survivors, having more than two chronic health conditions and public insurance (compared to private insurance) were associated with the presence of moderate/severe distress. Among survivors experiencing moderate/severe distress, lack of insurance was associated with decreased utilization of mental health care. CONCLUSIONS: Having cancer as an AYA may exacerbate disparities in psychological health within the Hispanic/Latino population.

RESUMEN

PURPOSE OF REVIEW: There is a growing population of adolescent and young adult (AYA, ages 15-39 years) cancer patients and survivors, and the field of AYA oncology is rapidly evolving. Despite an increased focus on survival and quality of life for AYAs, gaps in knowledge remain. The current review focuses on what is known across several domains unique to AYA cancer care as well as areas of improvement and future directions in research and intervention. RECENT FINDINGS: Due to the developmental stages included in the AYA age range, a cancer diagnosis and treatment can affect relationships, education and employment, finances, and long-term health differently than diagnoses in younger or older populations. Recent studies that have focused on these unique aspects of AYA cancer care, including health-related quality of life (HRQoL), fertility, financial toxicity, barriers to clinical trial enrollment, genetic predisposition, and survivorship care are included in the current review. SUMMARY: Although studies have described many of the challenges faced by AYAs across the cancer continuum from diagnosis to survivorship, more work is needed, particularly in systematically measuring HRQoL, eliminating barriers to clinical trial enrollment, addressing financial toxicity, and increasing access to fertility preservation and high-quality survivorship care.

RESUMEN

Relapsed or refractory pediatric patients with B-acute lymphoblastic leukemia (B-ALL) have high rates of toxicities and relapse, and novel therapy is needed. We present a case of a 5-year-old male child with high-risk B-ALL that was refractory to several re-induction regimens. He was put into minimal residual disease-negative remission after re-induction with chemotherapy plus overlapping rituximab, inotuzumab ozogamicin, and blinatumomab, termed mini-hyper-CVD (cyclophosphamide, vincristine, and dexamethasone) plus CRIB (condensed rituximab, inotuzumab ozogamicin, and blinatumomab). This regimen was well tolerated, and he received his transplant and engrafted with no significant infections, toxicities, or sinusoidal obstruction syndrome. This is the first reported use of a condensed sequential immunotherapy/chemotherapy regimen in a pediatric leukemia patient.
