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.

Article Synopsis
  • Rhabdomyosarcoma (RMS) treatment has improved, but high-risk patients still struggle with poor survival rates due to issues like PAX3/7-FOXO1 fusion proteins that cause metastasis and resistance to therapy.
  • This study focused on TRIB3, a regulator of FOXO1, finding that higher TRIB3 expression in RMS tumors correlates with the fusion protein's presence and contributes to cell proliferation.
  • Genetic inhibition of TRIB3 not only reduced PAX3-FOXO1 levels and affected signaling pathways but also delayed tumor growth and improved survival rates in vivo, indicating TRIB3 could be a promising therapeutic target for aggressive RMS.

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).

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.
