Racial Disparities in Treatment and Outcomes of Pediatric Hepatoblastoma.

Pediatric Hepatoblastoma is a rare malignancy of the liver. This study used the National Cancer Database (NCDB) to identify 1068 patients diagnosed with hepatoblastoma from 2004 to 2020. χ 2 and Analysis of Variance testing, as well as Kaplan-Meier, Cox Regression, and multinomial logistic regression models were used. Data was analyzed using SPSS version 27, and statistical significance was set at α=0.05. Our results found Black patients experienced a significantly lower median survival rate compared with White patients, a difference which persisted after controlling for covariates. Black patients were also less likely to receive surgery and chemotherapy and more likely to be from low-income households than White patients. White patients had a significantly shorter inpatient hospital stay compared to Black patients and were more likely to receive treatment at more than 1 CoC accredited facility. There was no significant difference in grade, size of tumor, metastasis, or time of diagnosis to surgery. This study showed Black patients experienced inferior overall survival when diagnosed and treated for hepatoblastoma compared to White patients.

Survival and treatment in older patients with ewing sarcoma: an analysis of the national cancer database.

BACKGROUND: Ewing sarcoma (EWS) is a malignancy which primarily arises in adolescence and has been studied extensively in this population. Much less is known about the rare patient cohort over the age of 40 at diagnosis. In this study, we describe the survival outcomes and clinical characteristics of this population. METHODS: This retrospective cohort study utilized the National Cancer Database (NCDB) to identify 4600 patients diagnosed between 2004 through 2019. Of these patients, 4058 were under the age of 40 and 542 were over 40. Propensity score 1:1 matching was performed according to sex and race. Univariate and multivariate logistic regression was performed to generate odds ratios (OR) and a Multivariate Cox regression model was used to generate a hazard ratio (HR) for patients over 40. Kaplan-Meier curves were used to estimate survival from diagnosis to death between age groups. Chi-square tests were used to compare demographic and socioeconomic patient characteristics. IBM statistics version 27.0 was used. p < 0.05 was used to indicate statistical significance. RESULTS: EWS patients older than 40 experienced worse survival outcomes compared to patients under the age of 40. 5-year survival was 44.6% for older patients vs. 61.8% for younger patients (p < 0.05). A multivariate Cox proportional hazards model showed that age was independently associated with inferior survival. (HR 1.96; p < 0.05). EWS patients over the age of 40 were more likely to have tumors originating from the vertebral column (16.1% vs 8.9%; p < 0.05) and cranium (5.3% vs. 2.9%; p < 0.05) and had a higher rate of axial tumors (31.6% vs. 18.5%; p < 0.05) compared to patients under 40. Additionally, patients older than 40 experienced a significantly longer delay between the date of diagnosis and initiation of systemic treatment (36.7 days vs. 24.8 days; p < 0.05) and were less likely to receive adjuvant chemotherapy (93.4% vs. 97.9%; p < 0.05). CONCLUSION: An age over 40 is associated with decreased survival for patients with EWS. Due to the rarity of EWS in this cohort, the optimal role of systemic treatment remains unknown and has yet to be clearly elucidated. Consequently, our findings suggest that older patients receive disparities in treatment which may be contributing to decreased survival rates.

Assessing the Safety and Efficacy of Tranexamic Acid Usage in Osteogenesis Imperfecta Patients.

BACKGROUND: Osteogenesis Imperfecta (OI) usually causes an increased fracture burden and bone deformity, with subsequent operations common. In addition to skeletal manifestations, there is a potential increase in bleeding susceptibility due to the increased frequency of orthopedic procedures, warranting investigation into methods to mitigate this risk. This study aims to evaluate the safety and efficacy of tranexamic acid (TXA) usage to reduce intraoperative blood loss in children with OI. We want to assess the potential benefits, risks, and complications involved with TXA use in this patient population. METHODS: TXA-receiving patients (cases) were matched 1:1 with non-TXA-receiving controls on the following criteria: age within 2 years, bone category, and OI Type. Descriptive statistics were used to summarize the data. Fisher Exact Test was performed to compare transfusion status between groups. A Wilcoxon Rank Sum test was performed to assess differences between the groups in days of stay, length of surgery, and estimated blood loss (EBL). All analyses were conducted using SAS version 9.4. P <0.05 was considered statistically significant. RESULTS: Our TXA-receiving population of 30 patients consisted of 11 females and 19 males. One patient was OI type I, 13 were OI type III, 14 were OI type IV, and 2 were categorized as Other (not Type I through Type IV). We found a significant difference in transfusion status ( P =0.02), with zero TXA patients requiring a transfusion compared with 20% of the control cases. There is also a significant difference in median EBL ( P =0.0004) between groups, with TXA patients having decreased intraoperative EBL (20 vs. 62.5 mL). There was also a difference in median days of postoperative stay between TXA-receiving and non-TXA-receiving patients ( P =0.001; 2.6 vs. 4 d). CONCLUSIONS: Our study concluded that TXA use in OI patients is associated with lower perioperative transfusions and intraoperative blood loss rates. These results support the standard usage of TXA in these patients to reduce intraoperative blood loss. LEVEL OF EVIDENCE: Level III.

Increased Risk of Fracture, Dislocation, and Hospitalization Are Associated With Collision in Contact Sports.

Purpose: To quantitatively determine whether there is an added risk of orthopaedic injury attributable to the collision forces that athletes participating in collision-contact (CC) sports regularly encounter. Methods: The National Electronic Injury Surveillance System was used to collect data on patients presenting to an emergency department with a contact sports-related injury between 2014 and 2020. Select contact sports were classified as either belonging to a CC or noncollision-contact (NCC) sports group based on involvement of frequent and intentional player-to-player collisions. Results: From 2014 to 2020, 25,784 patients with team-based sports related injuries presented to an emergency department, of whom 7,591 sustained an injury during a CC sport and 18,193 during a NCC sport. The CC group was associated with significantly increased odds of sustaining at least 1 fracture (odds ratio [OR] 1.4, 95% confidence interval [CI] 1.35-1.52) (P < .001), dislocation (OR 1.2, 95 % CI 1.06-1.33) (P < .001), and being admitted into the hospital (OR 1.6, 95% CI 1.34-1.86) (P < .001), compared with the NCC group. Conclusions: We found that frequent and intentional high-energy collisions associated with CC sports significantly increase the risk of sustaining fractures and dislocations. Furthermore, we found that that the injuries sustained by players engaging in CC sports required hospitalization at a significantly greater rate than those sustained in contact sports that do not involve frequent and intentional player-to-player collisions. Level of Evidence: Level III, prognostic (retrospective cohort study).
