The predictive power of coping strategies of pediatric oncology patients on their quality of life and their attitudes toward diseases.

Pediatric oncology patients face several physical and psychological challenges that can significantly impact their quality of life (QoL) and attitudes toward their illness. Coping strategies are pivotal in managing the emotional and physical burdens of disease. This study aimed to examine the impact of coping strategies of pediatric oncology patients on their QoL and attitudes towards their illness. The descriptive, correlational, and cross-sectional study was conducted with 112 pediatric oncology patients aged 10-18 years. The Sociodemographic Form, Pediatric Cancer Coping Scale (PCCS), Pediatric Quality of Life Inventory (PedsQL), and Child Attitude Towards Illness Scale (CATIS) were used for data collection. Significant correlations were identified between cognitive coping, defensive coping, and CATIS (p<.001). The PCCS and subdimensions significantly predicted CATIS (p<.001), accounting for 15.3% of the cognitive and defensive coping variation. However, there was no relationship between PCCS total and subdimension scores on PedsQL (p=.534). The PedsQL and subdimensions significantly predicted CATIS (p<.001) and accounted for 27.2% of the variation in physical health summary score, emotional functioning, psychosocial health summary score, and total PedsQL score. The study reveals that cognitive coping strategies positively predict attitudes toward illness, whereas defensive coping strategies have an inverse effect. The study proposes that comprehensive care models in pediatric oncology support effective coping mechanisms and enhance the QoL of those who receive them.

Radiation recall reaction induced by gemcitabine/docetaxel in children: A retrospective study on risk factors and outcomes.

Radiation recall reaction (RRR) is a rare inflammatory reaction developing in a previously irradiated field after a triggering agent. In pediatric patients, it is poorly understood and deficiently studied. Gemcitabine-docetaxel (G/D) in childhood cancer is mainly used as a salvage regimen for sarcomas. We aim to describe RRR triggered by G/D in children. Retrospective review of 21 patients receiving G/D along with radiotherapy at two hospitals from 2010 until 2022. RRR was considered as any toxicity occurring after G/D administration in a previously irradiated field. RRR features were described. Fisher's and Mann-Whitney tests were utilized to analyze the risk factors involved. Sixteen episodes of RRR developed in 16 (76.2%) patients. RRR mainly involved deep layers of the skin (58%) and occurred predominantly after two G/D cycles. The mean time between radiotherapy and chemotherapy was 28.5days (0-1359days), and the mean radiation volume 391mL (157-1810mL) for RRR. RRR treatment was mainly systemic steroids, with partial responses in six of 11 (58%) patients. Re-exposure to G/D was associated with a high rate of recurrence in nine of 15 (56.2%), prompting drug discontinuation. The major risk factors for RRR after G/D include, without statistical significance, a larger volume of the irradiated field and a shorter interval between chemotherapy and radiotherapy. The incidence of RRR after G/D in the pediatric population is higher than previously reported. Drug re-exposure is usually followed by recurrence. Higher irradiated volumes and a shorter time to the start of chemotherapy could be related with an increased risk of RRR.

Comprehensive fertility preservation can be offered in a timely manner around gonadotoxic therapy in children and adolescents.

Treatment for certain childhood cancers and nonmalignant conditions can lead to future infertility and gonadal failure. The risk of treatment delay must be considered when offering fertility preservation (FP) options. We examined the timeline from FP referral to return to treatment (RTT) in pediatric patients who underwent FP due to iatrogenic risk for infertility. A retrospective review was performed of patients with FP consultation due to an increased risk of iatrogenic infertility at Ann & Robert H. Lurie Children's Hospital of Chicago from 2018 to 2022. Data on diagnosis, age, treatment characteristics, and procedure were collected. A total of 337 patients (n=149 with ovaries, n=188 with testes) had an FP consultation. Of patients with ovaries, 106 (71.1%) underwent ovarian tissue cryopreservation (OTC), 10 (6.7%) completed ovarian stimulation/egg retrieval (OSER), and 33 (22.1%) declined FP. Of the patients with testes, 98 (52.1%) underwent testicular tissue cryopreservation (TTC), 48 (25.5%) completed sperm banking (SB), and 42 (22.3%) declined FP. Median time from referral to FP consultation was short (ovaries: 2days, range: 0-6; testes: 1day, range: 0-5). OSER had a significantly longer RTT versus OTC and no FP (52.5 vs.19.5 vs. 12days, p=.01). SB had a significantly quicker RTT compared to TTC or no FP (9.0 vs. 21.0 vs. 13.5days; p=.008). For patients who underwent OTC/TTC and those who declined FP, there was no significant difference in time from consultation to treatment. It is feasible to promptly offer and complete FP with minimal delay to disease-directed treatment.

Concomitant Wilms tumor and autosomal dominant polycystic kidney disease.

Concomitant Wilms tumor (WT) and autosomal dominant polycystic kidney disease (ADPKD) is exceedingly rare, presenting a diagnostic and technical challenge to pediatric surgical oncologists. The simultaneous workup and management of these disease processes are incompletely described. We performed a retrospective analysis of patients treated at our institution with concomitant diagnoses of WT and ADPKD. We also review the literature on the underlying biology and management principles of these conditions. We present three diverse cases of concomitant unilateral WT and ADPKD who underwent nephrectomy. One patient had preoperative imaging consistent with ADPKD with confirmatory testing postoperatively, one was found to have contralateral renal cysts intraoperatively with confirmatory imaging post nephrectomy, and one was diagnosed in childhood post nephrectomy. All patients are alive at last follow-up, and the patient with longest follow-up has progressed to end-stage kidney failure requiring transplantation and dialysis in adulthood. All patients underwent germline testing and were found to have no cancer predisposition syndrome or pathogenic or likely pathogenic variants for WT. Concomitant inheritance of ADPKD and development of WT are extremely rare, and manifestations of ADPKD may not present until late childhood or adulthood. ADPKD is not a known predisposing condition for WT. When ADPKD diagnosis is made by family history, imaging, and/or genetic testing before WT diagnosis and treatment, the need for extensive preoperative characterization of cystic kidney lesions in children and increased risk of post-nephrectomy kidney failure warrant further discussion of surgical approach and perioperative management strategies.

Parent-provider communication dynamics during the pediatric oncology diagnostic process in Guatemala: A qualitative study.

Effective communication is founded on bidirectional participation from families and healthcare providers. In adult medicine, bidirectional communication promotes treatment adherence and builds the family-provider relationship. However, the relationship between communication styles in pediatrics remains poorly understood, particularly in culturally diverse settings. This study aims to investigate parent-provider communication dynamics and parental involvement during diagnostic cancer communication in Guatemala. This qualitative study included 20 families of children with cancer and 10 providers at Unidad Nacional de Oncología Pediátrica in Guatemala. Psychoeducation and diagnostic conversations between parents, psychologists, and oncologists were recorded and thematically analyzed using a priori and novel codes exploring communication behaviors, parental engagement, and interpersonal dynamics. Participating parents had children with various diagnoses. Only 15% of fathers and 5% of mothers reported education beyond primary school. Providers spoke 68% of words during psychoeducation and 85% of words during diagnosis conversations. Providers used supportive communication behaviors providing explanations, demonstrating verbal attentiveness, and soliciting questions and non-supportive behaviors including paternalistic talk. Parental participation was considered active when they asked questions, expressed hopes or concerns, or asserted their opinions, and non-active when participation was limited to brief responses to closed-ended questions. Supportive provider communication often encouraged active participation; non-supportive communication did not. Furthermore, active parental participation prompted supportive communication from providers, while non-active participation did not. Our findings highlight the bidirectional nature of effective communication, establishing that provider communication styles both influence and are influenced by parental participation, and emphasizing the importance of supportive provider communication for patient-centered care.

Health-related quality of life among pediatric patients with acute lymphoblastic leukemia: An exploratory cross-sectional study.

Improved survival rates broadened the pediatric oncology focus to include health-related quality of life (HRQoL). This cross-sectional study aimed to examine HRQoL by treatment phase and disease risk level in pediatric patients with B-cell acute lymphoblastic leukemia (B-ALL), including those in early survivorship. A subset of data from a larger prospective cohort study was analyzed. Data were collected from 73 patients (73 parent reports and 28 self-reports). Parent proxy and self-report PROMIS measures assessed HRQoL across treatment phases (early intensive, maintenance, and off treatment) and disease risk groups (standard vs high). Analyses assessed the relationship between parent proxy and patient self-reports and the differences in HRQoL among treatment phases and risk groups. Parent proxy reports generally indicated worse fatigue, pain interference, and mobility compared with patient self-reports. Self-reports in the early intensive treatment group suggested worse depressive symptoms, fatigue, mobility, and upper extremity function compared with those in later phases. Parent proxy reports showed worse fatigue and depressive symptoms in early intensive treatment group relative to those in later phases. Patient self-reports in the maintenance group demonstrated the best peer relationships scores. Parent proxy reports in the high-risk group reported significantly higher depressive symptoms and fatigue compared with the standard-risk group. Differences in HRQoL suggest targets for further assessment and intervention. The early treatment and immediate post-survivorship periods may represent particularly critical time points. Longitudinal studies with larger and diverse samples should further explore HRQoL trajectories in this population.

Radiotherapy-associated Sensorineural Hearing Loss in Pediatric Oncology Patients.

During the radiotherapeutic treatment of pediatric oncology patients, they would be at a latent risk of developing ionizing radiation-induced ototoxicity when the cochlea or auditory nerve is located within the radiation field. Sensorineural hearing loss (SNHL) is an irreversible late complication of radiotherapy, and its incidence depends on various factors such as the patient's hearing sensitivity, total radiation dose to the cochlea, radiotherapy fractionation regimen, age and chemoradiation. Importantly, this complication exhibits serious challenges to adult survivors of childhood cancer, as it has been linked to impairments in academic achievement, psychosocial development, independent living skills, and employment in the survivor population. Therefore, early detection and proper management can alleviate academic, speech, language, social, and psychological morbidity arising from hearing deficits. In the present review, we have addressed issues such as underlying mechanisms of radiation-induced SNHL, audiometric findings of pediatric cancer patients treated with radiotherapy, and management and protection measures against radiation-induced ototoxicity.

Transfusional hemosiderosis in childhood cancer patients and survivors.

Children treated for cancer are at risk for adverse effects of iron due to transfusions administered during prolonged marrow suppression, which may increase exposure to toxic forms of iron, extrahepatic iron accumulation, and long-term organ damage. This study aimed to characterize the severity and organ distribution of clinically significant, multisystem iron overload (IO) in an at-risk cohort of pediatric cancer patients. This was a retrospective, cross-sectional study of childhood cancer patients who underwent a magnetic resonance imaging (MRI) due to clinical concern for IO. Data regarding cancer type and treatment, transfusion history, MRI and laboratory results, and treatment for IO were collected. Severity of IO was analyzed by non-parametric tests with respect to clinical characteristics. Of the 103 patients, 98% of whom had a Cancer Intensity Treatment Rating (ITR-3) of 3 or higher, 53% (54/102) had moderate or greater hepatic siderosis, 80% (77/96) had pancreatic siderosis, 4% (3/80) had cardiac siderosis, and 45% (13/29) had pituitary siderosis and/or volume loss. Pancreatic iron was associated with both cardiac (p=.0043) and pituitary iron (p=.0101). In the 73 off-therapy patients, ferritin levels were lower (p=.0008) with higher correlation with liver iron concentration (LIC) (p=.0016) than on-therapy patients. Fifty-eight subjects were treated for IO. In this heavily treated cohort of pediatric cancer patients, more than 80% had extrahepatic iron loading, which occurs with significant exposure to toxic forms of iron related to decreased marrow activity in setting of transfusions. Further studies should examine the effects of exposure to reactive iron on long-term outcomes and potential strategies for management.

Abstract B067: A mixed-methods health services analysis of disparities and social vulnerabilities in childhood cancer survivors’ long-term follow-up care

Abstract Pediatric cancer affects &amp;gt;15,000 US children annually. Treatment advances have led to an increase in those surviving the disease, and these patients must be managed to control their long-term comorbidities. Unfortunately, a majority are nonadherent to post-treatment care guidelines and become lost to follow-up. This is especially true for those from underserved backgrounds, including survivors who are Black and Latine. To help understand this disparity, we studied the organization and delivery of pediatric cancer survivorship care at an urban comprehensive cancer center. Research included: 1) a qualitative study exploring healthcare barriers and facilitators of survivors’ adherence to long-term follow-up care, as determined by N=31 key informants (pediatric oncology care providers, administrators), and; 2) a retrospective cohort study (2007- 2020) among N&amp;gt;350 survivors (10% Black, 28% Latine, 12% Asian; 47% from vulnerable neighborhoods) assessing social determinants of health (SDoH) and its cofactors, adjusted for vital status. Interviews were recorded, transcribed, and thematically analyzed using software (K&amp;gt;.70). Three major themes emerged in survivors’ adherence: 1) healthcare system-level influences (69%), SDoH (25%), and intra/interpersonal factors (16%). At the system-level, informants noted opportunities to strengthen adherence, especially for survivors from underserved backgrounds, including the provision of greater social support (14%), easing appointment scheduling (11%), offering high-quality ambulatory and specialty care within the system upon entering young adulthood (12%), and cultural competency training for staff (6%). Among SDoH, informants noted transportation and geographic challenges in accessing the healthcare system (25%), insurance coverage for follow-up care (17%), and strengthening trust with marginalized communities (17%). For intra/interpersonal factors, time- and age-related changes in survivors’ medical needs were acknowledged as barriers to be overcome (28%), along with providing greater patient education (11%) and heightened salience of follow-up care (17%). Conversely, the provider-patient relationship was noted as a strength in promoting adherence (23%). Retrospective cohort results revealed that survivors’ attendance at dedicated clinics was suboptimal (52% &amp;gt;= 2 years off-therapy), as were rates of system-wide ambulatory care encounters 3+ and 5+ years post-therapy. At the bivariate level, non-Hispanic Black survivors (68%), adolescents (58%), and those with CNS tumors (81%) had the lowest likelihood of survivorship clinic attendance (p&amp;lt;.05)–underscoring qualitative findings on SDoH. Area-level SDoH indices were unrelated to the cohort’s adherence, highlighting qualitative findings on intra/interpersonal barriers and facilitators. These data lend insights into transformations possible within the organization and delivery of healthcare to young survivors, especially those from underrepresented backgrounds, including greater attention to SDoH and strengthening cultural competence among health system employees.

Abstract B135: Association of residential economic and racial segregation with metastatic disease at diagnosis in pediatric patients with solid tumors

Abstract Background: Disparities in pediatric cancer outcomes by race and ethnicity may be influenced by neighborhood characteristics, particularly residential economic and racial segregation. Prior to a new cancer diagnosis, pediatric patients are vulnerable to structural barriers embedded in their neighborhoods. In particular, residential economic and racial segregation may impede access to initial care for early cancer detection, increasing the likelihood of presenting with distant metastatic disease at diagnosis that can translate to excess morbidity and mortality. This study assesses the association of residential economic and racial segregation as measured by the Index of Concentration at the Extremes (ICE) with the likelihood of presenting with distant metastatic disease (as compared to local or locoregional disease) among children newly diagnosed with cancer. Methods: We studied a cohort of pediatric patients diagnosed with solid tumors at Children’s Healthcare of Atlanta between 2010 and 2016. Patients’ ZIP codes were linked to the ICE, which was constructed at the ZIP code level using American Community Survey 2012-2016 five-year estimates. The ICE was categorized into tertile 1 (most deprived) through tertile 3 (most privileged). Multivariable logistic regression models were used to assess the association between residential economic and racial segregation, defined by tertiles of the ICE, and the likelihood of presenting with distant metastatic disease, as determined by initial cancer staging. All models adjusted for patient- and disease-level covariates, including age, sex at birth, health insurance type, and cancer type. Results: Among 829 patients identified in our analytic sample, 27.6% had distant metastatic disease at diagnosis. Living in the most deprived (ICE tertile 1) versus the most privileged (ICE tertiles 2/3) neighborhoods was significantly associated with a higher likelihood of presenting with distant metastatic disease at diagnosis (adjusted odds ratio [OR] = 1.46; 95% confidence interval [CI] = 1.03 to 2.07; p=0.03). Additionally, non-Hispanic Black patients living in the most deprived neighborhoods were more likely to have distant metastatic disease at diagnosis compared to non-Hispanic White patients living in the most privileged neighborhoods (adjusted OR = 1.83; 95% CI = 1.15 to 2.92; p=0.002). Conclusion: This study provides new insights into how residential economic and racial segregation is associated with metastatic disease at diagnosis among children presenting with a new solid tumor. Our findings highlight the need for geographically targeted interventions to improve community care, resource allocation and investment, and public policies aimed at supporting this vulnerable patient population.

Premature ovarian insufficiency in pediatric cancer patients: a 10 year Rady Children's hospital experience.

To highlight the occurrence of premature ovarian insufficiency in pediatric cancer patients and determine which patient characteristics or treatment modalities are associated with ovarian failure and recovery. Between August 2011-August 2021, 36 of 2,661 patients with cancer were identified to have subsequent ovarian failure. Data collected included cancer type, diagnosis age, types of chemotherapy, bone marrow transplant or radiation treatment, peak FSH, peak AMH, GnRHa treatment, type of hormone replacement therapy, and if ovarian function recovery occurred. The most common cancer type identified was ALL. The mean age of diagnosis was 8.5±4.3 years and mean age of peak FSH value was 12.6±2.8 years. Most patients (97.2 %) were treated with alkylating agents and 72.2 % received radiation. Most patients (72.2 %) received hormone therapy, and 15.8 % of patients received GnRHa Lupron. Ten patients (27.8 %) had ovarian function recovery. Diagnosis age and treatment type were recovery predictors in multivariate regression modeling. Each year older in age was associated with a 30 % decrease in odds of recovery (OR: 0.7, CI: 0.5-0.95, p=0.035), and alkylating agent treatment without transplant was associated with a 3-fold increase in odds of recovery (OR: 3, CI: 2.7-564, p=0.007). This retrospective review demonstrates that POI can occur in pediatric cancer survivors, emphasizing the importance of educating patients on potential long-term effects of cancer treatment and importance of routine surveillance. This study confirmed that recovery of ovarian function is possible, especially when diagnosed at a younger age, making continued monitoring essential.
