Summary: This study aimed to investigate the clinical outcomes of SBRT in the treatment of oligometastatic RCC. The results showed that SBRT had excellent local control and minimal toxicity, and there were no significant differences in survival between patients with synchronous and metachronous oligometastasis. Patients with solitary oligometastasis had better overall survival.

Summary: Although rare, treatment-related secondary malignancies are significant concerns following childhood malignant disease treatment. Irradiation-induced sarcomas develop in the radiation field as a different type of sarcoma from the primary tumor after a latency period of at least 3 years. Desmoid tumors as a result of radiation therapy are extremely rare.

Summary: This study evaluated the clinical features, treatment approaches, and outcomes of glial tumors in children. The results showed that around 40.6% of pediatric brain tumors were glial tumors, with astrocytoma and ependymoma being the most common types. There were significant age differences between the two types of tumors. Headaches, abnormal gait or coordination, vomiting, and cranial nerve palsies were the most common symptoms or signs.
