Molecular characteristics and therapeutic vulnerabilities across paediatric solid tumours

Area of Science:

• Pediatric Oncology
• Cancer Genomics
• Translational Research

Background:

• Childhood tumors exhibit distinct molecular features compared to adult malignancies, including origins, epidemiology, and genetic drivers.
• Despite advances in molecular characterization, translating this knowledge into clinical benefits for pediatric cancer patients remains a challenge.

Purpose of the Study:

• To provide a comprehensive overview of the molecular landscape of pediatric solid tumors.
• To discuss preclinical models and therapeutic vulnerabilities for improved treatment strategies.
• To highlight challenges and opportunities in translating scientific progress into clinical benefits.

Main Methods:

• Review of current literature on pediatric solid tumor genomics and microenvironment.
• Analysis of novel preclinical platforms for testing therapeutic strategies.
• Examination of molecular profiling and mechanism-of-action-based treatments.

Main Results:

• Pediatric tumors possess unique genomic alterations and interact differently with their microenvironment compared to adult cancers.
• Preclinical platforms are being developed to better model tumor heterogeneity and predict treatment response.
• Real-time molecular profiling offers potential for more precise, mechanism-based treatments.

Conclusions:

• There is a critical need for rigorous preclinical validation of biomarkers and targets to advance molecularly stratified clinical trials for pediatric cancers.
• Translating the vast scientific progress in understanding pediatric tumors into tangible clinical benefits requires overcoming significant challenges.
• Future efforts should focus on integrating molecular insights with advanced preclinical testing to optimize therapeutic strategies for children with cancer.
