Background: Pediatric oncology has witnessed remarkable advancements over the past five decades, resulting in significant improvements in survival rates for many childhood cancers. Despite these achievements, numerous clinical challenges continue to affect diagnosis, treatment, supportive care, survivorship, and quality of life among pediatric cancer patients. The unique biological characteristics of childhood cancers, treatment-related toxicities, psychosocial issues, healthcare disparities, and long-term complications require specialized multidisciplinary management.

Objective: This review examines major clinical challenges in pediatric oncology, focusing on diagnostic difficulties, treatment-related complications, supportive care issues, survivorship concerns, emerging therapeutic approaches, and future directions in pediatric cancer management.

Methods: A comprehensive review of current literature, clinical guidelines, and recent advances in pediatric oncology was conducted to evaluate challenges and opportunities in contemporary pediatric cancer care.

Results: Clinical challenges in pediatric oncology include delayed diagnosis, treatment toxicity, infection risk, psychosocial burden, limited access to novel therapies, treatment resistance, and long-term adverse effects. Emerging precision medicine approaches, immunotherapy, molecular diagnostics, and survivorship programs have improved outcomes but also introduced new complexities.

Conclusion: Addressing clinical challenges in pediatric oncology requires integrated multidisciplinary care, enhanced access to innovative therapies, improved supportive care systems, and long-term survivorship planning. Continued research and global collaboration are essential to further improve outcomes and quality of life for children with cancer.
