RESUMO

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.

RESUMO

INTRODUCTION: Venous thromboembolism (VTE), a common complication in cancer patients, occurs more often during the initial phase of treatment. However, information on VTE beyond the first two years after diagnosis ('late VTE') is scarce, particularly in young survivors. METHODS: We examined the risk of, and factors associated with, late VTE among adolescents and young adults (AYA, 15-39 years) diagnosed with cancer (2006-2018) who survived ≥2 years. Data were obtained from the California Cancer Registry linked to hospitalization, emergency department and ambulatory surgery data. We used non-parametric models and Cox proportional hazard regression for analyses. RESULTS: Among 59,343 survivors, the 10-year cumulative incidence of VTE was 1.93 % (CI 1.80-2.07). The hazard of VTE was higher among those who had active cancer, including progression from lower stages to metastatic disease (Hazard Ratio (HR) = 10.41, 95 % confidence interval (CI): 8.86-12.22), second primary cancer (HR = 2.58, CI:2.01-3.31), or metastatic disease at diagnosis (HR = 2.38, CI:1.84-3.09). The hazard of late VTE was increased among survivors who underwent hematopoietic cell transplantation, those who received radiotherapy, had a VTE history, public insurance (vs private) or non-Hispanic Black/African American race/ethnicity (vs non-Hispanic White). Patients with leukemias, lymphomas, sarcoma, melanoma, colorectal, breast, and cervical cancers had a higher VTE risk than those with thyroid cancer. CONCLUSIONS: VTE risk remained elevated ≥2 years following cancer diagnosis in AYA survivors. Active cancer is a significant risk factor for VTE. Future studies might determine if late VTE should prompt evaluation for recurrence or second malignancy, if not already known.

RESUMO

PURPOSE: To examine the relationship between guideline-concordant care (GCC) on the basis of national clinical practice guidelines and survival in children (0-14 years), adolescents and young adults (AYAs, 15-39 years), and adults (40 years and older) with osteosarcoma, and to identify sociodemographic and clinical factors associated with receipt of GCC and survival. METHODS: We used data from the California Cancer Registry (CCR) on patients diagnosed with osteosarcoma during 2004-2019, with detailed treatment information extracted from the CCR text fields, including chemotherapy regimens. Multivariable logistic and Cox proportional hazard regression were used for statistical analyses. RESULTS: Of 1,716 patients, only 47% received GCC, with variation by age at diagnosis: 67% of children, 43% of AYAs, and 30% of adults. In multivariable models, patients who received part or all care (v none) at specialized cancer centers were more likely to receive GCC. AYAs and adults were less likely to receive GCC than children (odds ratio [OR], 0.38 [95% CI, 0.30 to 0.50] and OR, 0.40 [95% CI, 0.28 to 0.56], respectively). In a model excluding adults, patients treated by pediatric (v medical) oncologists were more likely to receive GCC (OR, 3.44 [95% CI, 2.40 to 4.94]). Patients with metastatic osteosarcoma at diagnosis who did not receive GCC had a greater hazard of death (hazard ratio [HR], 2.02 [95% CI, 1.55 to 2.63]) but no statistical differences were found in those diagnosed at earlier stages (HR, 1.15 [95% CI, 0.92 to 1.43]). CONCLUSION: GCC was associated with improved survival in patients with metastatic osteosarcoma in California. However, we found disparities in the delivery of GCC, highlighting the need for target interventions to improve delivery of GCC in this patient population.

RESUMO

Children with cancer in low- and middle-income countries were disproportionately impacted by the COVID-19 pandemic, but little is known about how adolescents and young adults (AYAs) with cancer were affected. Sixty-seven physicians and nonphysician providers were interviewed about their experiences caring for AYAs with cancer in Latin America. Quotes related to the COVID-19 pandemic were identified and grouped into themes. Barriers from the COVID-19 pandemic included limited space, restrictions on travel, reduced funding, limited staff, limited services, and changes to treatment. However, improvements to care that arose from the COVID-19 pandemic included better access to distance learning and telemedicine.
