Large Population Analysis of Secondary Cancers in Pediatric Leukemia Survivors.

ABSTRACT: INTRODUCTION:Survivors of childhood cancer have an increased risk of developing a subsequent secondary malignant neoplasm (SMN). Among five-year survivors of primary cancer, SMNs account for nearly half of non-relapse deaths, which make them the most frequent cause of non-relapse mortality. Leukemia is the most common childhood cancer and the five-year survival rate of leukemia has drastically improved over the past two decades. Therefore, the chances of developing SMNs are higher in pediatric (0-19 years) leukemia survivors. METHODS:The US based Surveillance, Epidemiology, and End Results (SEER-18) database (1973-2014) was probed for SMNs in the pediatric population (age ? 19). Variables Sequence-number central, primary site and ICCC3WHO were used to identify the first and second cancers among patients who developed SMN. RESULTS:Our SEER database analysis found 99,380 cases of pediatric primary malignancies (0-19 years), of which 1803 (1.81%) patients developed SMN. The breakdown of SMNs in pediatric leukemia survivors (n = 251) showed thyroid carcinoma (18.33% of cases) as the most common second cancer, followed by sarcoma (15.14%), astrocytoma (10.36%), lymphoma (9.56%), salivary gland carcinoma (7.17%), melanoma (4.38%), and breast cancer (3.98%). Interestingly, we found that over 76% of SMNs that were developed by leukemia patients occurred within 20 years after initial leukemia diagnosis. However, some SMNs occur during later age, for example, the mean age for breast cancer occurrence in leukemia survivors is 26.20 ± 8.53 years after initial leukemia diagnosis. CONCLUSIONS:Our study presented comprehensive rates of SMNs among pediatric cancers survivors, and the potential SMNs for pediatric leukemia survivors. This information could we used by oncologists, patients, patient families, and cancer researchers to understand the long-term risks that are associated with the development of SMNs in pediatric leukemia survivors.

Project description:Background: Survivors of pediatric sepsis often develop new morbidities and deterioration in quality of life after sepsis, leading to a need for improved follow-up for children who survive sepsis. Objective: To implement a follow-up system for pediatric sepsis survivors in a pediatric health system. Methods: We performed a retrospective case series of patients treated for sepsis from October 2018 through October 2019 in a pediatric intensive care unit in a quaternary children's hospital, and describe implementation of a follow-up system for sepsis survivors. Program planning started in 2017 with multidisciplinary meetings including physical, occupational, and speech therapists, teachers, neuropsychologists, and coordinators from other survivorship programs (neonatology, stroke, and oncology). In 2018, a workshop was held to consult with local and national experts. The Pediatric Sepsis Survivorship Program launched in October 2018 led by a nurse coordinator who met with families to educate about sepsis and offer post-discharge follow-up. Patients with high pre-existing medical complexity or established subspecialty care were referred for follow-up through existing care coordination or subspecialty services plus guidance to monitor for post-sepsis morbidity. For patients with low-moderate medical complexity, the nurse coordinator administered a telephone-based health-assessment 2-3 months after discharge to screen for new physical or psychosocial morbidity. Patients flagged with concerns were referred to their primary physician and/or to expedited neuropsychological evaluation to utilize existing medical services. Results: Of 80 sepsis patients, 10 died, 20 were referred to care coordination by the program, and 13 had subspecialty follow-up. Five patients were followed in different health systems, four were adults not appropriate for existing follow-up programs, four remained hospitalized, and four were missed due to short stay or unavailable caregivers. The remaining 20 patients were scheduled for follow-up with the Pediatric Sepsis Program. Nine patients completed the telephone assessment. Four patients were receiving new physical or occupational therapy, and one patient was referred for neuropsychology evaluation due to new difficulties with attention, behavior, and completion of school tasks. Conclusions: Implementation of an efficient, low-cost pediatric sepsis survivorship program was successful by utilizing existing systems of care, when available, and filling a follow-up gap in screening for select patients.

Project description:Background/objectivesMost of the studies on functional outcomes in pediatric survivors of cancers and bone marrow failure disorders have been conducted in North American, European, and Oceanian populations, with few studies having been performed in China. The objective of this study was to evaluate psychosocial outcomes in a cohort of Chinese pediatric survivors diagnosed with cancer or conditions requiring hematopoietic stem cell transplantation (HSCT), and to identify clinical and behavioral factors associated with adverse psychosocial outcomes.MethodsThis was a cross-sectional survey study. We recruited pediatric survivors of cancer or inherited disorder requiring HSCT at ≤18 years old and were ≥6 months post-treatment. Parents completed the St. Jude Children's Research Hospital After Completion of Therapy questionnaire to report their child's emotional functioning, social functioning, attention/concentration and behavior. Multivariable general linear modeling was used to identify clinical, treatment and behavioral factors associated with psychosocial outcomes, adjusting for sex, age and cancer diagnoses.ResultsNinety-five pediatric survivors were recruited (62.1% male; mean [standard deviation] age 9.7 [3.4] years; 4.1 [2.6] years post-diagnosis). They were diagnosed with bone marrow failure disorders (23.2%), hematological malignancies (45.3%) or solid tumors (23.2%). Compared with survivors with no current health problems, those with more than one current health problem performed worse in emotional functioning (Estimate = 2.42, SE = 0.88, P = 0.008) and social functioning (Estimate = 2.90, SE = 1.64, P = 0.03). Higher pain interference was significantly associated with worse emotional functioning (Estimate = 0.19, SE = 0.08, P = 0.03) and attention functioning (Estimate = 0.26, SE = 0.11, P = 0.03). Compared with survivors who reported less sleep problems, those who had more sleep problems demonstrated poorer emotional functioning (Estimate = 0.30, SE = 0.08, P = 0.001). Survivors who had a longer duration of screen usage per day reported more impairment on attention and behavior functioning than those who had a shorter duration of screen usage per day (both P<0.5).ConclusionSurvivors who were diagnosed at a younger age or had unaddressed/untreated health problems may require additional psychological evaluation. The implementation of psychosocial assessments during routine long-term follow-up care may help to identify high-risk patients during the early phase of survivorship. Rehabilitation interventions should address modifiable behavioral factors (e.g. sleep habits, screen time and chronic pain).
