RESUMEN
Multidisciplinary tumor boards (MTBs) facilitate decision-making among subspecialists in the care of oncology patients, but the mechanisms by which they enhance outcomes remain incompletely understood. Our aim was to measure the agreement between sarcoma MTBs and radiology reports' disease assessment and management recommendations. This single-center IRB-approved retrospective study evaluated cases presented at a weekly sarcoma MTB from 1 August 2020 to 31 July 2021. Cases without clinical notes, imaging studies, or radiology reports were excluded. The data collected included the patient's clinical status at the time of the MTB, the treatment response assessment by the MTB and radiologists (stable disease; partial response; complete response; progressive disease/recurrence), and the recommendations of the radiology reports and of the MTB. The agreement between the initial radiologist review and MTB on disease assessment and recommendations was analyzed using kappa statistics. In total, 283 cases met the inclusion criteria. Radiology reports provided recommendations in 34.3% of cases, which were adhered to by the ordering providers in 73.2% of cases. The agreement between MTBs and radiology reports was moderate in disease assessment (86.2% agreement; κ = 0.78; p < 0.0001) and negligible in recommendations (36% agreement; κ = 0.18; p < 0.0001). Radiologists were more likely to assign progressive disease/recurrence than MTBs (54.4% vs. 44.4%; p < 0.001) and to recommend short-term imaging follow-up more commonly than MTBs (46.4% vs. 21.7%; p < 0.001). At a tertiary care center, radiologists' isolated interpretations of imaging findings and management recommendations frequently differ from the MTB's consensus, reflecting the value of multidisciplinary discussions incorporating the patient's clinical status and the available treatment options into the final radiographic assessment.
RESUMEN
BACKGROUND: Ewing sarcoma (ES) is a malignant bone tumor most commonly affecting non-Hispanic White (NHW) adolescent males, though recognition among Hispanic individuals is rising. Prior population-based studies in the United States (US), utilizing Surveillance, Epidemiology, and End Results (SEER) have shown higher all-cause mortality among White Hispanics, Blacks, and those of low socioeconomic status (SES). Florida is not part of SEER but is home to unique Hispanic populations including Cubans, Puerto Ricans, South Americans that contrasts with the Mexican Hispanic majority in other US states. This study aimed to assess racial/ethnic disparities on incidence and survival outcomes among this diverse Florida patient population. METHODOLOGY: Our study examined all patients diagnosed with osseous ES (2005-2018) in Florida (n = 411) based on the state's population-based cancer registry dataset. Florida Age-adjusted Incidence Rates (AAIRs) were computed by sex and race-ethnicity and compared to the equivalent populations in SEER. Cause-specific survival disparities among Florida patients were examined using Kaplan-Meier analysis. Univariable and multivariable analyses using Cox regression were performed for race/ethnicity, with adjustment for age, sex, year of diagnosis, site of disease, staging, SES, and insurance type. RESULTS: There was a significantly higher incidence of osseous ES in Florida Hispanic males (AAIR 2.6/1,000,000); (95% CI: 2.0-3.2 per 1,000,000; n = 84) compared to the SEER Hispanic males (AAIR 1.2/1,000,000;1.1-1.4 per 1,000,000; n = 382). Older age, distant metastasis, lack of chemotherapy or surgical resection were statistically significant determinants of poor survival while SES, insurance status and race-ethnicity were not. However, among nonmetastatic ES, Florida Hispanics had an increased risk of death compared to Florida NHW (adjusted Hazard Ratio 2.32; 95%CI: 1.20-4.46; p = 0.012). CONCLUSIONS: Florida Hispanic males have a higher-than-expected incidence of osseous ES compared to the US. Hispanics of both sexes show remarkably worse survival for nonmetastatic disease compared to NHW. This disparity is likely multifactorial and requires further in-depth studies.

DICER1 syndrome is a rare genetic disorder predisposing young patients to multiple types of cancer. A 17-year-old woman with a history of mixed Sertoli-Leydig cell tumor and juvenile granulosa cell tumor of the left ovary at age 14 presented with a pelvic mass. She underwent fertility preservation cytoreductive surgery and the pathology showed high-grade sarcoma with rhabdomyosarcomatous differentiation. After the surgery, patient received one cycle of chemotherapy but her disease continued to progress. She therefore underwent total hysterectomy, right salpingo-oophorectomy and hyperthermic intraperitoneal chemotherapy followed by consolidation chemotherapy. Magnetic resonance imaging revealed no evidence of the disease before and after the completion of her chemotherapy. Genetic testing confirmed the DICER1 pathogenic variant. However, she presented again with a recurrence of the disease 6 months later and ultimately died of the disease 11 months after the surgery. Our case demonstrates the challenging management of this rare disease in a young patient and the need for new and effective treatments.
RESUMEN
The impact of nonbiological factors (NBF) on survival was investigated in a large cohort of adolescents and young adults (AYA) with lymphoma in the United States (US). We found that uninsured and Medicaid AYA beneficiaries with classical Hodgkin lymphoma (cHL) and non-Hodgkin lymphoma (NHL) are at significantly increased risk of death when compared with their insured counterpart even after adjustment for other factors affecting survival. Increased risk of death was also noted for Non-Hispanic Black (NHB) patients with cHL and NHL when compared to Non-Hispanic White (NHW) patients, however, only Hispanic patients with NHL were found to have a significantly increased mortality risk while those with cHL were not. NHL AYA patients residing in lower-income counties are at increased risk of death. The strong association of NBF with survival indicates opportunities to improve the survival of AYA lymphoma patients by improving access/quality of care in the US.

OPINION STATEMENT: Head and neck osteosarcoma (HNOS) is a rare subtype of sarcoma that most commonly arises in the mandible or maxilla. Treatment for HNOS typically involves a multidisciplinary and multimodal approach depending on the size, grade, and histological subtype. Surgery by sarcoma-experienced head and neck surgeons and orthopedic oncologists remains a crucial component of treatment in all subtypes of HNOS, particularly for those with low-grade histology, which can be treated definitively with surgical resection if negative margins are obtained. Negative surgical margins are of utmost prognostic importance, and neoadjuvant or adjuvant radiation should be considered in patients with positive (or anticipated positive) margins/residual postoperative disease. Current data favors the use of (neo)adjuvant chemotherapy in patients with high-grade HNOS to improve overall survival but must be individualized to weigh benefits and risks of the short- and long-term effects of treatment. Our center uses a multidisciplinary treatment plan and notes anecdotal improvement in treatment outcomes with a combined surgical and ifosfamide-containing chemotherapeutic approach with radiotherapy for local control if positive margins. Large volume cohorts and adequate randomized control trials assessing the efficacy of chemotherapy in HNOS are scant and additional research and multi-institutional collaboration are needed to study polychemotherapeutic and radiation treatment regimens and outcomes more adequately.

Sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD) posthematopoietic stem cell transplantation (HSCT) is often diagnosed using the modified Seattle (MS) or European Society for Blood and Marrow Transplantation (EBMT) criteria. We hypothesized that strict application of these criteria could affect the timing of diagnosis and incidence of SOS/VOD. We collected data on 215 transplants performed in 184 patients at a single pediatric hematopoietic stem cell transplantation center, which were divided into 3 cohorts. Clinical diagnosis and treatment of SOS/VOD was documented in 13% of transplants (cohort 1). On retrospective review, 49% of transplant events met either MS and/or EBMT criteria, however, were not diagnosed with SOS/VOD (cohort 2); remaining 38% of transplant events did not meet MS or EBMT criteria and were not diagnosed with SOS/VOD (cohort 3). Day+100 overall survival was significantly inferior for cohort 1 (78%) compared with cohorts 2 or 3 (92% and 95%, P=0.01) with no difference between cohorts 2 and 3 (P=0.5). Patients diagnosed with SOS/VOD >day+13 had worse day+100 overall survival when compared with those diagnosed ≤day13 (64.3% and 100%, respectively, P=0.02). This study highlights the value of careful clinical assessment to guide diagnosis and the need to refine diagnostic criteria for SOS/VOD in children.

Childhood cancer is the leading cause of nonaccidental death in children and adolescents. Over the past 50 years, development of novel therapies and improvements in supportive care have led to improvements in long-term survival rates. However, there remains great morbidity associated with cancer treatment among childhood cancer survivors, and the outcomes for patients who relapse remain poor. The introduction of precision medicine, an approach that uses the understanding of genetic and biochemical profiles of a disease (as enabled by next-generation sequencing) to tailor treatment to a patient, has quickly started to change the diagnostic and therapeutic landscape of pediatric oncology. With its use, a better understanding of tumor biology, improved classification systems for various cancers, and genetically and molecularly targeted therapeutic strategies have been developed. We review the implementation of precision medicine in pediatric oncology and its effect on diagnosis, management, and treatment of pediatric cancers. [Pediatr Ann. 2022;51(1):e8-e14.].

BACKGROUND: The survival of patients with acute promyelocytic leukemia (APL) has dramatically improved with the use of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO). However, because of the complexity of the initial management, early mortality (EM) remains a major contributor to treatment failure. It is less known whether advances in treatment, urgent access to specialized care, and broad availability of ATRA/ATO have reduced EM in the last 2 decades. Furthermore, the influence of sociodemographic factors on the risk of EM also remains unclear. METHODS: This study used the Surveillance, Epidemiology, and End Results program to characterize the impact of sociodemographic factors on the rates of EM and overall survival (OS) in patients with APL diagnosed between 1992 and 2015. RESULTS: In all, 2224 cases were identified (895 who were younger than 40 years and 1329 who were 40 years old or older); 47.9% had a county-level median household income of $59,630 or higher, 49.0% belonged to counties where more than 31% of adults held at least a bachelor's degree, and 86.0% resided in urban areas. The rate of EM declined from 31.5% in 1992-1995 to 15.9% in 2012-2015 for all patients. It improved for patients younger than 40 years (27.4% in 1992-1995 vs 5.4% in 2012-2015; P < .001) and for patients 40 years old or older but not to the same extent (35.2% in 1992-1995 vs 22.2% in 2012-2015; P = .02). Importantly, improvements in EM were not seen among patients residing in rural areas, with the rate remaining higher than 20% in 2012-2015. The 3-year OS rate was 49.2% for patients with APL diagnosed in 1992-1995 and 76.4% for patients diagnosed in 2012-2015. CONCLUSIONS: These findings confirm consistent improvements in EM and OS for patients with APL and point to the challenge of further extending these improvements in EM rates to older patients and to those living in rural areas.

BACKGROUND: Survival among patients diagnosed with acute promyelocytic leukemia (APL) has significantly improved with the use of all-trans retinoic acid and arsenic trioxide. However, the need for immediate diagnosis and access to specialized care and the cost associated with APL management can potentially act as barriers for disadvantaged patients. The influence of sociodemographic factors on the outcomes of patients with APL remains unclear. METHODS: The authors used the National Cancer Institute's Surveillance, Epidemiology, and End Results program to characterize the impact of sociodemographic factors on survival in patients younger than 65 years with APL. RESULTS: The authors identified 1787 cases: 816 who were younger than 40 years and 971 who were 40 years old or older. Insured patients who were younger than 40 years had an improved 5-year overall survival (OS) rate in comparison with patients without insurance. Among patients who were 40 years or older, having insurance (other than Medicaid) was associated with better survival than being a Medicaid beneficiary or being uninsured, whereas patients with Medicaid had improved 5-year OS in comparison with uninsured patients. In a multivariate analysis of patients younger than 40 years, a higher risk of death was associated with being male, being diagnosed in earlier years, and being uninsured. For patients who were 40 years old or older, mortality increased with increasing age and for both Medicaid and uninsured patients in comparison with insured patients. CONCLUSIONS: Despite the high cure rate experienced by patients with APL, patients younger than 65 years without insurance and those 40 years old or older with Medicaid are at a significant disadvantage in comparison with patients with insurance. These findings point to an opportunity to improve survival in APL by addressing access to care.

Langerhans cell histiocytosis (LCH) often has a recurrent and refractory course despite multiagent treatment modalities. Common relapse treatments include intense or prolonged cytotoxic chemotherapy regimens. There are a few prior reports that the nonsteroidal anti-inflammatory drug indomethacin demonstrated activity against bone LCH. Here we report indomethacin as a successful treatment for a case of chronic skin LCH that failed multiple prior chemotherapy regimens. This experience supports the need for trials to investigate indomethacin as a treatment for LCH both in the relapsed or refractory setting as well as potential combination or maintenance therapy in newly diagnosed patients.

An increase in the incidence of deep vein thrombosis (DVT) has been reported in pediatric patients over the past decade. The presence of central venous line (CVL) is a major contributing risk factor with conflicting data on the relative risk of DVT with various types of central lines. We aimed to assess the incidence of and identify potential risk factors for DVT overall and with different types of CVL individually. A retrospective chart review of pediatric patients with a CVL placed at Cleveland Clinic Children's from 2011 to 2016 was conducted. Data collected included demographics, potential risk factors, CVL characteristics and related thrombotic events. The study cohort consisted of 376 CVLs in 325 patients between 0 and 26 years of age. There were 1.6 thrombi per 10,000 line-days (95% confidence interval: 1.0, 2.5), and the overall incidence of DVT was 5.1%. The incidence of DVT was highest with tunneled catheters (5/16=31%) versus with peripherally inserted central catheters (4/111=3.6%) or with ports (10/249=4%, P<0.001), and whereas there were overarching significant risk factors for CVL-associated thrombi, these risk factors differed in significance when analyzed by the CVL type. The study supports the need for continued improvement in pediatric hospital practices for early identification of patients at a higher thrombosis risk.

OBJECTIVES: The prevalence of obesity is rapidly increasing among Indian children, who, in general, are more prone to develop metabolic complications at an early age. Valproate and phenytoin are commonly used antiepileptic drugs in children. This study aimed to assess the parameters of the metabolic syndrome in Indian children with epilepsy on valproate or phenytoin monotherapy. METHODS: This cross-sectional study recruited children from the Pediatric Epilepsy Clinic, Department of Pediatrics, Kalawati Saran Children Hospital, New Delhi from March 2012 to September 2012. All consecutive children diagnosed with epilepsy as per International League Against Epilepsy definition aged 3-18 years on valproate or phenytoin monotherapy for at least 6 months were enrolled at a tertiary care children's hospital in Northern India. After clinical and anthropometric evaluation (including body mass index [BMI] and waist circumference), the blood samples were analyzed for fasting serum glucose, total cholesterol, high-density lipoprotein-cholesterol, and serum triglyceride. RESULTS: Children with BMI >95(th) centile and waist circumference >90(th) centile were not significantly different among children on valproate and phenytoin monotherapy. Children on valproate had significantly higher mean serum triglyceride (96.9 mg/dL vs. 77.6 mg/dL; P < 0.001) and total cholesterol (148.3 mg/dL vs. 132.8 mg/dL; P = 0.002) levels as compared to children on phenytoin monotherapy. CONCLUSIONS: The lipid abnormalities may be observed in children on valproate or phenytoin therapy and may warrant periodic screening.
RESUMEN
We describe a pediatric patient with an atypical teratoid rhabdoid tumor (AT/RT) exclusively of the lumbar spine, with a different presentation from the two previously reported pediatric lumbar AT/RT. AT/RT are rare pediatric tumors of the central nervous system, with a dismal prognosis. Although there is sufficient literature on brain AT/RT, spinal AT/RT continues to be a rare entity, with a lumbar location even less frequently reported. A 30-month-old African American boy with multiple comorbidities presented with the inability to ambulate, encopresis and urinary dribbling. The MRI showed an intradural extramedullary mass extending downwards from the L3-4 level. He underwent an L3-S2 laminoplasty. The surgically resected mass was marked by sheets of cells with large nuclei and prominent nucleoli. The tumor cells stained with antibodies to synaptophysin and CAM5.2, and showed no immunoreactivity to INI-1 antibody. He was diagnosed with a World Health Organization Grade IV AT/RT. There was no mutation detected in the SMARCB1 gene on a comprehensive analysis of his blood. The boy is currently being treated according to the Medical University of Vienna AT/RT protocol, with no evidence of tumor recurrence 8 months after surgery. To our knowledge, this is the only report of a lumbar AT/RT in an African American child.
