RESUMEN

BACKGROUND: Sociodemographic and clinical factors associated with diagnostic delays in pediatric, adolescent, and young adult cancers are poorly understood. METHODS: Using the Optum Labs Data Warehouse's de-identified claims data for commercial health plan enrollees, we identified children (0-14 years) and adolescents/young adults (AYAs) (15-39 years) diagnosed with one of 10 common cancers from 2001 to 2017, who were continuously enrolled for 6 months preceding diagnosis. Time to diagnosis was calculated as days between first medical encounter with possible cancer symptoms and cancer diagnosis date. Median times from first symptom to diagnosis were compared using Wilcoxon rank sum test. Multivariable unconditional logistic regression identified sociodemographic factors associated with longer time (>3 months) to cancer diagnosis (from symptom onset). RESULTS: Of 47,296 patients, 87% presented prior to diagnosis with symptoms. Patients with central nervous system (CNS) tumors were most likely to present with symptoms (93%), whereas patients with cervical cancer were least likely (70%). Symptoms varied by malignancy. Of patients with symptoms, thyroid (105 days [range: 50-154]) and cervical (104 days [range: 41-151]) cancer had the longest median time to diagnosis. Females and patients at either end of the age spectrum were more likely to experience diagnosis delays of more than 3 months. CONCLUSION: In a commercially insured population, time to diagnosis varies by cancer type, age, and sex. Further work is needed to understand the patient, provider, and health system-level factors contributing to time from symptom onset to diagnosis, specifically in the very young children and the young adult patient population going forward.

RESUMEN

BACKGROUND: Approximately 5% of cancer patients in the United States presented with metastatic bone disease (MBD) at diagnosis. Current study explores the disparities in survival for patients with MBD. METHODS: Patients with the diagnosis of MBD at presentation for the five most common primary anatomical sites were extracted from Surveillance, Epidemiology, and End Results Census tract-level dataset (2010-2016). Kaplan-Meier and Cox Proportional Hazard models were used to evaluate survival, and prognostic factors for each cohort. Prognostic significance of socioeconomic status (SES) and insurance status were ascertained. RESULTS: The five most common anatomical-sites with MBD at presentation included "lung" (n = 59 739), "prostate" (n = 19 732), "breast" (n = 16 244), "renal and urothelium" (n = 7718) and "colon" (n= 3068). Lower SES was an independent risk factor for worse disease-specific survival (DSS) for patients with MBD originating from lung, prostate, breast and colon. Lack of insurance was an independent risk factor for worse DSS for MBD patients with primary tumors in lung and breast. CONCLUSIONS: MBD patients from the five most common primary sites demonstrated SES and insurance-related disparities in disease-specific survival. This is the first and largest study to explore SES and insurance-related disparities among patients specifically afflicted with MBD. Our findings highlight vulnerability of patients with MBD across multiple primary sites to financial toxicity.

RESUMEN

BACKGROUND: Adolescent and young adult (AYA) cancer survivors experience psychological distress often because of cancer and its treatment. However, no prior studies have evaluated the additional medical expenditures and health care utilization associated with psychological distress in AYA cancer survivors. METHODS: AYA cancer survivors and a comparison matched group of adults with no history of cancer were identified from 2011-2016 Medical Expenditure Panel Survey data. Medical expenditures and health care utilization were evaluated with multivariable regression models. RESULTS: AYA cancer survivors were more likely to have psychological distress (11.5% of 1757) than adults with no history of cancer (5.8% of 5227). The prevalence of psychological distress was found to be high many years after the diagnosis, with 11.2% reporting distress ≥20 years after their cancer diagnosis. AYA cancer survivors with psychological distress were more likely to smoke and have chronic conditions and were less likely to exercise regularly in comparison with AYAs with no history of psychological distress. AYA cancer survivors with psychological distress had additional annual medical expenses ($4415; 95% CI, $993-$9690), office visits (2.80; 95% CI, 0.23-6.15), and use of prescription medications/medication renewals (11.58; 95% CI, 5.70-19.47) in comparison with AYA cancer survivors without psychological distress. Additional annual medical expenses of psychological distress were $2600 higher in AYA cancer survivors than adults without a history of cancer ($1802; 95% CI, $440-$3791). CONCLUSIONS: These results highlight the substantial economic burden associated with psychological distress in AYA cancer survivors. This research could inform survivorship care plans and interventions addressing the psychological needs of AYA cancer survivors.

RESUMEN

BACKGROUND: Adolescent and young adult (AYA) patients with cancer are underrepresented on cancer clinical trials (CCTs), and most AYAs are treated in the community setting. Past research has focused on individual academic institutions, but factors impacting enrollment vary across institutions. Therefore, we examined the patterns of barriers and facilitators between high- and low-AYA enrolling community-based clinics to identify targets for intervention. MATERIALS AND METHODS: We conducted 34 semi-structured interviews with stakeholders employed used at National Cancer Institute Community Oncology Research Program (NCORP) affiliate sites ("clinics"). Stakeholders (eg, clinical research associates, patient advocates) were recruited from high- and low-AYA enrolling clinics. We conducted a content analysis and calculated the percentage of stakeholders from each clinic type that reported the barrier or facilitator. A 10% gap between high- and low-enrollers was considered the threshold for differences. RESULTS: Both high- and low-enrollers highlighted insufficient resources as a barrier and the presence of a patient eligibility screening process as a facilitator to AYA enrollment. High-enrolling clinics reported physician gatekeeping as a barrier and the improvement of departmental collaboration as a facilitator. Low-enrollers reported AYAs' uncertainty regarding the CCT process as a barrier and the need for increased physician endorsement of CCTs as a facilitator. CONCLUSIONS: High-enrolling clinics reported more barriers downstream in the enrollment process, such as physician gatekeeping. In contrast, low-enrolling clinics struggled with the earlier steps in the CCT enrollment process, such as identifying eligible trials. These findings highlight the need for multi-level, tailored interventions rather than a "one-size-fits-all" approach to improve AYA enrollment in the community setting.

RESUMEN

INTRODUCTION: Advances in diagnostic and treatment modalities for high grade bone sarcomas (HGBS) of lower extremity (LE) have enabled limb salvage resections as a feasible first-line surgical option. However, amputations are still performed. Impact of amputation on survival and predictive factors for amputation and the stage at presentation for HGBS of LE remain unknown. METHODS: National Cancer Database was used to extract 5781 cases of high-grade bone sarcoma of the LE from 2004 to 2017. Kaplan-Meier and Cox regression were used to determine the impact of amputation on survival. Chi square test and logistic regression were used to assess the correlation of predictive factors with amputation and stage at presentation. RESULTS: Amputation [hazard ratio (HR) 1.516; 95% confidence interval (CI) 1.259-1.826; p < 0.001] and advanced stage (HR 0.248; 95% CI 0.176-0.351; p < 0.001) were independent predictors of poor overall survival. The impact of amputation on survival was most pronounced for pediatric and adolescents and young adults (AYA) age groups (18% decrease in 10-year survival). Amputation was more likely to be performed among those with nonprivate insurance (HR 1.736; 95% CI 1.191-2.531; p = 0.004), a finding that was mirrored for advanced stage at presentation (HR 0.611; 95% CI 0.414-0.902; p = 0.013). DISCUSSION: Amputation is an independent predictor of poor outcomes among patients with HGBS of LE. The impact of amputation on survival is the highest for the pediatric and AYA age group. Nonprivate insurance is associated with increased likelihood of amputation and an advanced stage at presentation among patients with high-grade bone sarcoma of the LE. This is the largest study highlighting insurance-related disparities in this cohort.

RESUMEN

While many higher-education institutions dramatically altered their operations and helped mitigate COVID-19 transmission on campuses, these efforts were rarely fully extended to surrounding communities. A community pandemic-response program was launched in a college town that deployed epidemiological infection-control measures and health behavior change interventions. An increase in self-reported preventive health behaviors and a lower relative case positivity proportion were observed. The program identified scalable approaches that may generalize to other college towns and community types. Building public health infrastructure with such programs may be pivotal in promoting health in the postpandemic era. (Am J Public Health. 2022;112(8):1142-1146. https://doi.org/10.2105/AJPH.2022.306880).

RESUMEN

PURPOSE: The ideal local treatment modality for pelvic and sacral Ewing sarcoma (EWS) is controversial. METHODS: We present the data from the American College of Surgeon's National Cancer Database (NCDB) and the National Cancer Institute's Surveillance, Epidemiology and End Result (SEER) database to investigate the impact of local treatment modalities on survival for nonmetastatic pelvic and sacral Ewing sarcoma. Local treatment includes "surgery," "radiation," and a combination of "surgery and radiation." RESULTS: A total of 235 cases from SEER and 285 cases from NCDB were analyzed. Patients with "localized" stage (intraosseous) in the SEER database did not show any statistically significant difference in the disease-specific survival (DSS) for any of the local treatment modalities. Similar findings were observed for overall survival among patients with American Joint Committee on Cancer (AJCC) stage II and III in the NCDB database. However, patients with nonmetastatic disease, particularly regional disease (extraosseous), showed improved DSS with surgery only, in the SEER. CONCLUSION: We found similar levels of efficacy for different treatment modalities for patients with intraosseous and AJCC II and III pelvic and sacral EWS. "Radiotherapy" is the most common local treatment modality employed in the United States. A prospective, randomized controlled trial with a direct head-to-head comparison is needed for a definitive conclusion.

RESUMEN

BACKGROUND: We have analyzed sex, race/ethnicity or socioeconomic disparities in the incidence of metastatic bone disease (MBD). METHODS: Patients with the diagnosis of MBD at presentation for five most common primary anatomical sites was extracted from Surveillance, Epidemiology, and End Results Census tract-level dataset. Mean incidence of MBD for different sex, racial/ethnic and socioeconomic groups were compared. RESULTS: The five most common anatomical sites with MBD at presentation include "lung: (n = 59 739), "prostate" (n = 19 732), "breast" (n = 16 244), "renal" (n = 7718) and "colon" (n = 3068). There was an increase in incidence of MBD among cancers originating from prostate (annual percentage change [APC] 4.94), renal (APC 2.55), and colon (APC 3.21) (p < 0.05 for all). Non-Hispanic Blacks had higher incidence of MBD for prostate and breast primary sites (p < 0.001). Non-Hispanic American Indian Alaskan Native had higher incidence of MBD for cancers originating from renal (p < 0.001) and colon (p = 0.049). A higher incidence of MBD was seen in lower socioeconomic status (SES) groups for the selected sites (p < 0.001). CONCLUSIONS: These findings suggest that there are multiple sex-related, racial/ethnic and SES disparities in the incidence of MBD from the 5 most common primary sites. Higher incidence seen among lower SES suggests delay in diagnosis and limited access to screening modalities.

RESUMEN

Implementation science (IS) has garnered attention within oncology, and most prior IS work has focused on adult, not pediatric, oncology. This narrative review broadly characterizes IS for pediatric oncology. It includes studies through 2020 using the following search terms in PubMed, Ovid Medline, and Cochrane: "implementation science," "pediatric," "childhood," "cancer," and "oncology." Systematic review was not performed due to the limited number of heterogeneous studies. Of 216 articles initially reviewed, nine were selected as specific to IS and pediatric oncology. All nine examined oncologic supportive care, cancer prevention, or cancer control. The supportive care focus is potentially due to the presence of cooperative study groups such as the Children's Oncology Group, which efficiently drive cancer-directed therapy changes through clinical trials. Future IS within pediatric oncology should embrace this ecosystem and focus on cancer control interventions that benefit patients across multiple cancer types and patients treated outside cooperative group studies.

RESUMEN

BACKGROUND: Despite efforts to increase participation of adolescents and young adults (AYAs; 15-39 years) in cancer clinical trials (CTs), enrollment remains very low. Even when provided access to CTs, AYAs are less likely to participate than children and older adults. A better understanding of oncologist- and AYA survivor-reported barriers, facilitators, and potential areas for CT enrollment improvement is needed. PROCEDURES: From December 2019 to August 2020, we conducted 43 semi-structured interviews with oncologists (n = 17) and AYA cancer survivors (n = 26) who were offered and/or participated in CTs at cancer centers in California and Utah. Thematic analyses were used to interpret the findings. RESULTS: Oncologists identified a lack of available CTs, strict eligibility criteria, lack of awareness of open CTs, and poor communication between pediatric and adult oncologists as major barriers to enrollment. AYA cancer survivors identified financial and psychosocial barriers, and a poor understanding of what a CT means and its potential benefits as barriers to enrollment. Areas for improvement identified by oncologists and AYAs include educational, financial, and psychosocial support to AYAs. Oncologists also emphasized the need to increase CT availability, improve awareness of open CTs, and better communication between both pediatric and adult oncologists and oncologists and AYAs. CONCLUSIONS: For AYAs with cancer, a lack of CT eligibility and physician awareness of open CTs likely factor into their lower CT enrollment. Potential strategies to improve AYA enrollment in CTs require comprehensive collaboration between pediatric and adult institutions, as well as educational, psychosocial, and financial support to AYAs.

RESUMEN

BACKGROUND: Ewing sarcoma (EWS) and osteosarcoma (OS) require multidisciplinary treatment. Care at specialized cancer centers (SCC: Children's Oncology Group affiliated and/or National Cancer Institute-designated cancer center) has been found to improve outcomes in patients with leukemia, but studies have not considered location of care and outcomes in EWS and OS patients, an ideal group to evaluate given their specialized multidisciplinary treatment needs. METHODS: Patients hospitalized with primary EWS and OS (2000-2014) were identified using the California Cancer Registry linked with hospitalization data. Patients were divided into age groups (0-18, 19-39, ≥40 years), and classified on whether they received all versus part/none of their inpatient treatment at a SCC within 1 year of diagnosis. Multivariable Cox proportional hazards regression identified factors associated with survival. RESULTS: There were 531 ES and 959 OS patients. Five-year overall survival was better for patients with EWS (all: 63% vs. part/none: 42%) and OS (all: 64% vs. part/none: 47%) who received all of their treatment at a SCC. After adjusting for sociodemographic and clinical factors, receiving all inpatient cancer treatment at a SCC was associated with superior overall survival (EWS HR: 0.49, CI 0.37-0.67; OS HR: 0.78, CI 0.63-0.97). CONCLUSION: Our results suggest that treatment for EWS and OS at a SCC is associated with significantly improved survival even after adjustment for known prognostic factors. The superior survival among those treated at SCCs may be due to having greater access to clinical trials and services at SCCs.

RESUMEN

BACKGROUND: Long-term safety of topical calcineurin inhibitors is not well understood. APPLES (A Prospective Pediatric Longitudinal Evaluation to Assess the Long-Term Safety of Tacrolimus Ointment for the Treatment of Atopic Dermatitis; NCT00475605) examined incidence of lymphoma and other cancers in a pediatric population with atopic dermatitis. OBJECTIVE: To quantify incident malignancies during 10 years in children with atopic dermatitis who used topical tacrolimus for ≥6 weeks. METHODS: Standardized incidence ratios for cancer events were analyzed relative to sex-, age-, and race-matched control data from national cancer registries. RESULTS: There were 7954 eligible patients enrolled at 314 sites in 9 countries. During 44,629 person-years, 6 confirmed incident cancers occurred (standardized incidence ratio, 1.01; 95% confidence interval, 0.37-2.20). No lymphomas occurred. LIMITATIONS: Observational prospective cohort study. CONCLUSION: The cancer incidence was as expected, given matched background data. This finding provides no support for the hypothesis that topical tacrolimus increases long-term cancer risk in children with atopic dermatitis.

RESUMEN

BACKGROUND: Stagnant outcomes for adolescents and young adults (AYAs) 15-39 years of age with cancer are partly attributed to poor enrollment onto clinical trials. Initiatives have focused on increasing accrual, but changes at the population-level are unknown. We examined patterns of clinical trial participation over time in AYA patients with cancer. PROCEDURE: We utilized medical record data from AYAs in two population-based National Cancer Institute Patterns of Care Studies identified through the Surveillance, Epidemiology and End Results Program. Among 3135 AYAs diagnosed with non-Hodgkin lymphoma (NHL), Hodgkin lymphoma, acute lymphoblastic leukemia (ALL), and sarcoma, we used multivariate logistic regression to evaluate patient and provider characteristics associated with clinical trial enrollment. Interaction terms evaluated variation in clinical trial enrollment across patient and provider characteristics by year of diagnosis. RESULTS: From 2006 to 2012-2013, clinical trial participation increased from 14.8% to 17.9% (P < 0.01). Adjusting for patient and provider characteristics, we found lower clinical trial enrollment among those who were older at diagnosis, diagnosed with NHL vs ALL, treated by adult hematologist/oncologists only (vs pediatric hematologist/oncologists), and of non-Hispanic Black race/ethnicity (vs non-Hispanic White) (P < 0.05 for all). Interaction analyses indicate improved clinical trial enrollment from 2006 to 2012-2013 among young adults 25-29 years of age and the uninsured. CONCLUSIONS: Although disparities in enrollment onto clinical trials remain for AYAs with cancer, our study identified increasing overall clinical trial participation over time. Further, we identify promising trends in enrollment uptake among AYAs 25-29 years of age and the uninsured.

RESUMEN

OBJECTIVES: Major trials examining storage age of blood transfused to critically ill patients administered relatively few blood transfusions. We sought to determine if the storage age of blood affects outcomes when very large amounts of blood are transfused. DESIGN: A secondary analysis of the multicenter randomized Transfusion Requirement in Burn Care Evaluation study which compared restrictive and liberal transfusion strategies. SETTING: Eighteen tertiary-care burn centers. PATIENTS: Transfusion Requirement in Burn Care Evaluation evaluated 345 adults with burns greater than or equal to 20% of the body surface area. We included only the 303 patients that received blood transfusions. INTERVENTIONS: The storage ages of all transfused red cell units were collected during Transfusion Requirement in Burn Care Evaluation. A priori measures of storage age were the the mean storage age of all transfused blood and the proportion of all transfused blood considered very old (stored ≥ 35 d). MEASUREMENTS AND MAIN RESULTS: The primary outcome was the severity of multiple organ dysfunction. Secondary outcomes included time to wound healing, the duration of mechanical ventilation, and in-hospital mortality. There were 6,786 red cell transfusions with a mean (± SD) storage age of 25.6 ± 10.2 days. Participants received a mean of 23.4 ± 31.2 blood transfusions (range, 1-219) and a mean of 5.3 ± 10.7 units of very old blood. Neither mean storage age nor proportion of very old blood had any influence on multiple organ dysfunction severity, time to wound healing, or mortality. Duration of ventilation was significantly predicted by both mean blood storage age and the proportion of very old blood, but this was of questionable clinical relevance given extreme variability in duration of ventilation (adjusted r ≤ 0.01). CONCLUSIONS: Despite massive blood transfusion, including very old blood, the duration of red cell storage did not influence outcome in burn patients. Provision of the oldest blood first by Blood Banks is rational, even for massive transfusion.

RESUMEN

BACKGROUND: Sodium thiosulfate is an antioxidant shown in preclinical studies in animals to prevent cisplatin-induced hearing loss with timed administration after cisplatin without compromising the antitumour efficacy of cisplatin. The primary aim of this study was to assess sodium thiosulfate for prevention of cisplatin-induced hearing loss in children and adolescents. METHODS: ACCL0431 was a multicentre, randomised, open-label, phase 3 trial that enrolled participants at 38 participating Children's Oncology Group hospitals in the USA and Canada. Eligible participants aged 1-18 years with newly diagnosed cancer and normal audiometry were randomly assigned (1:1) to receive sodium thiosulfate or observation (control group) in addition to their planned cisplatin-containing chemotherapy regimen, using permuted blocks of four. Randomisation was initially stratified by age and duration of cisplatin infusion. Stratification by previous cranial irradiation was added later as a protocol amendment. The allocation sequence was computer-generated centrally and concealed to all personnel. Participants received sodium thiosulfate 16 g/m2 intravenously 6 h after each cisplatin dose or observation. The primary endpoint was incidence of hearing loss 4 weeks after final cisplatin dose. Hearing was measured using standard audiometry and reviewed centrally by audiologists masked to allocation using American Speech-Language-Hearing Association criteria but treatment was not masked for participants or clinicians. Analysis of the primary endpoint was by modified intention to treat, which included all randomly assigned patients irrespective of treatment received but restricted to those assessable for hearing loss. Enrolment is complete and this report represents the final analysis. This trial is registered with ClinicalTrials.gov, number NCT00716976. FINDINGS: Between June 23, 2008, and Sept 28, 2012, 125 eligible participants were randomly assigned to either sodium thiosulfate (n=61) or observation (n=64). Of these, 104 participants were assessable for the primary endpoint (sodium thiosulfate, n=49; control, n=55). Hearing loss was identified in 14 (28·6%; 95% CI 16·6-43·3) participants in the sodium thiosulfate group compared with 31 (56·4%; 42·3-69·7) in the control group (p=0·00022). Adjusted for stratification variables, the likelihood of hearing loss was significantly lower in the sodium thiosulfate group compared with the control group (odds ratio 0·31, 95% CI 0·13-0·73; p=0·0036). The most common grade 3-4 haematological adverse events reported, irrespective of attribution, were neutropenia (117 [66%] of 177 participant cycles in the sodium thiosulfate group vs 145 [65%] of 223 in the control group), whereas the most common non-haematological adverse event was hypokalaemia (25 [17%] of 147 vs 22 [12%] of 187). Of 194 serious adverse events reported in 26 participants who had received sodium thiosulfate, none were deemed probably or definitely related to sodium thiosulfate; the most common serious adverse event was decreased neutrophil count: 26 episodes in 14 participants. INTERPRETATION: Sodium thiosulfate protects against cisplatin-induced hearing loss in children and is not associated with serious adverse events attributed to its use. Further research is needed to define the appropriate role for sodium thiosulfate among emerging otoprotection strategies. FUNDING: US National Cancer Institute.

RESUMEN

OBJECTIVE: Our objective was to compare outcomes of a restrictive to a liberal red cell transfusion strategy in 20% or more total body surface area (TBSA) burn patients. We hypothesized that the restrictive group would have less blood stream infection (BSI), organ dysfunction, and mortality. BACKGROUND: Patients with major burns have major (>1 blood volume) transfusion requirements. Studies suggest that a restrictive blood transfusion strategy is equivalent to a liberal strategy. However, major burn injury is precluded from these studies. The optimal transfusion strategy in major burn injury is thus needed but remains unknown. METHODS: This prospective randomized multicenter trial block randomized patients to a restrictive (hemoglobin 7-8 g/dL) or liberal (hemoglobin 10-11 g/dL) transfusion strategy throughout hospitalization. Data collected included demographics, infections, transfusions, and outcomes. RESULTS: Eighteen burn centers enrolled 345 patients with 20% or more TBSA burn similar in age, TBSA burn, and inhalation injury. A total of 7054 units blood were transfused. The restrictive group received fewer blood transfusions: mean 20.3 ±â€Š32.7 units, median = 8 (interquartile range: 3, 24) versus mean 31.8 ±â€Š44.3 units, median = 16 (interquartile range: 7, 40) in the liberal group (P < 0.0001, Wilcoxon rank sum). BSI incidence, organ dysfunction, ventilator days, and time to wound healing (P > 0.05) were similar. In addition, there was no 30-day mortality difference: 9.5% restrictive versus 8.5% liberal (P = 0.892, χ test). CONCLUSIONS: A restrictive transfusion strategy halved blood product utilization. Although the restrictive strategy did not decrease BSI, mortality, or organ dysfunction in major burn injury, these outcomes were no worse than the liberal strategy (Clinicaltrials.gov identifier NCT01079247).

RESUMEN

PURPOSE: To investigate associations of sociodemographic factors-race/ethnicity, neighborhood socioeconomic status (SES), and health insurance-with survival for adolescents and young adults (AYAs) with invasive cancer. METHODS: Data on 80,855 AYAs with invasive cancer diagnosed in California 2001-2011 were obtained from the California Cancer Registry. We used multivariable Cox proportional hazards regression to estimate overall survival. RESULTS: Associations of public or no insurance with greater risk of death were observed for 11 of 12 AYA cancers examined. Compared to Whites, Blacks experienced greater risk of death, regardless of age or insurance, while greater risk of death among Hispanics and Asians was more apparent for younger AYAs and for those with private/military insurance. More pronounced neighborhood SES disparities in survival were observed among AYAs with private/military insurance, especially among younger AYAs. CONCLUSIONS: Lacking or having public insurance was consistently associated with shorter survival, while disparities according to race/ethnicity and neighborhood SES were greater among AYAs with private/military insurance. While health insurance coverage associates with survival, remaining racial/ethnic and socioeconomic disparities among AYAs with cancer suggest additional social factors also need consideration in intervention and policy development.
