RESUMO

INTRODUCTION: The assessment of quality of life (QoL) should be one of the main objectives in paediatric clinical trials. Even though researchers, regulators and advocates support the use of patient-reported outcomes (PROs), this has not been fully implemented. The aim of this study is to assess the measurement of QoL and the usage of PROs, palatability assessments and medication diaries in early-phase clinical trials for childhood and adolescent cancer. METHODS: Early-phase clinical trials for children and adolescents with cancer opened between 2005 and 2022 at the Royal Marsden Hospital (London, UK) and Vall d'Hebron University Hospital (Barcelona, Spain) were interrogated for trial characteristics and the use of QoL questionnaires, PROs, palatability assessments and medication diaries. RESULTS: Overall, 72 clinical trials were analysed: 12 (16.7%) evaluated QoL and eight (11.1%) evaluated PROs. Palatability was tested in 21/40 (52.5%) trials of oral drugs and 23/72 (31.9%) incorporated medication diaries. No studies mentioned patient involvement in the trial protocol. Use of PROs increased from one of 36 (2.8%) to seven of 36 (19.4%) between the first period (2005-2016) and the second period (2017-2022) (p = .02). Implementation of medication diaries increased from seven of 36 (19.4%) to 16/36 (44.4%) in each period, respectively (p = .02). CONCLUSION: Only a minor proportion of the international/multicentric early-phase trials evaluated included QoL/PROs and medication diaries or palatability questionnaires to help assess these, although this trend seems to be increasing over recent years. Greater implementation of QoL/PROs has the potential to improve the patient's wellbeing and facilitate symptom control, to enhance patient/parent involvement in future trial designs and to provide information for drug prioritisation.

RESUMO

Rhabdomyosarcoma (RMS), such as other childhood tumors, has witnessed treatment advancements in recent years. However, high-risk patients continue to face poor survival rates, often attributed to the presence of the PAX3/7-FOXO1 fusion proteins, which has been associated with metastasis and treatment resistance. Despite efforts to directly target these chimeric proteins, clinical success remains elusive. In this study, the main aim was to address this challenge by investigating regulators of FOXO1. Specifically, we focused on TRIB3, a potential regulator of the fusion protein in RMS. Our findings revealed a prominent TRIB3 expression in RMS tumors, highlighting its correlation with the presence of fusion protein. By conducting TRIB3 genetic inhibition experiments, we observed an impairment on cell proliferation. Notably, the knockdown of TRIB3 led to a decrease in PAX3-FOXO1 and its target genes at protein level, accompanied by a reduction in the activity of the Akt signaling pathway. Additionally, inducible silencing of TRIB3 significantly delayed tumor growth and improved overall survival in vivo. Based on our analysis, we propose that TRIB3 holds therapeutic potential for treating the most aggressive subtype of RMS. The findings herein reported contribute to our understanding of the underlying molecular mechanisms driving RMS progression and provide novel insights into the potential use of TRIB3 as a therapeutic intervention for high-risk RMS patients.

RESUMO

BACKGROUND: Brain tumors represent the most common cause of cancer-related death in children. Few studies concerning the palliative phase in children with brain tumors are available. OBJECTIVES: (i) To describe the palliative phase in children with brain tumors; (ii) to determine whether the use of palliative sedation (PS) depends on the place of death, the age of the patient, or if they received specific palliative care (PC). METHODS: Retrospective multicenter study between 2010 and 2021, including children from one month to 18 years, who had died of a brain tumor. RESULTS: 228 patients (59.2% male) from 10 Spanish institutions were included. Median age at diagnosis was 5 years (IQR 2-9) and median age at death was 7 years (IQR 4-11). The most frequent tumors were medulloblastoma (25.4%) and diffuse intrinsic pontine glioma (DIPG) (24.1%). Median number of antineoplastic regimens were 2 (range 0-5 regimens). During palliative phase, 52.2% of the patients were attended by PC teams, while 47.8% were cared exclusively by pediatric oncology teams. Most common concerns included motor deficit (93.4%) and asthenia (87.5%) and communication disorders (89.8%). Most frequently prescribed supportive drugs were antiemetics (83.6%), opioids (81.6%), and dexamethasone (78.5%). PS was administered to 48.7% patients. Most of them died in the hospital (85.6%), while patients who died at home required PS less frequently (14.4%) (p = .01). CONCLUSION: Children dying from CNS tumors have specific needs during palliative phase. The optimal indication of PS depended on the center experience although, in our series, it was also influenced by the place of death.

RESUMO

Kaposi sarcoma (KS) is an angioproliferative disease associated with human herpesvirus 8 (HHV-8). We report the case of a 10-year-old male from a high HHV-8 prevalence area, diagnosed with severe aplastic anemia who underwent an upfront hematopoietic stem cell transplantation (HSCT). Five months after transplant, the patient was diagnosed with KS with skin, mucosae, lymph nodes and lung involvement. After withdrawal of immunosuppression the patient achieved complete remission without requiring further treatments. KS may occur after HSCT in patients from high HHV-8 prevalence areas. Considering that, we propose that screening of HHV-8 by antibody testing could be considered in HSCT donors/recipients from these areas.
