Article Synopsis
- Craniopharyngioma (CP) is a benign tumor located mainly in the brain's chiasmatic-sellar region, with two main types: adamantinoma-like (ACP) and papillomatous (PCP), the latter mostly affecting adults.
- The study aimed to determine the disease-free survival in adults with newly diagnosed CP based on the quality of tumor removal and the effectiveness of irradiation, using data from 398 patients over a decade.
- Results showed that total tumor resection significantly lowers recurrence risk, while stereotactic irradiation after incomplete resection also yields favorable outcomes, with PCPs being less aggressive and less likely to recur after complete removal.

Despite significant progress in neuroimaging and introduction of new combined treatments for solid tumors, brain metastases are still adverse factor for overall survival. Brain metastases are diagnosed in 8-10% of patients and associated with extremely poor prognosis. These lesions result focal and general cerebral symptoms.

However, the tendency of these tumors to invade critical structures (such as optic pathways, the hypothalamic-pituitary system, the Willis circle vessels) often limits the possibility of a radical surgery.Craniopharyngiomas of the third ventricle represent the greatest challenge for surgery.

Unlabelled: Hypothalamic hamartoma (HH) is a dysplastic lesion fused with hypothalamus and followed by epilepsy, precocious puberty and behavioral disorders. Up to 50% of patients become free of seizures after surgery, but various complications occur in 1/4 of cases. Radiofrequency thermocoagulation, laser interstitial thermal therapy and stereotactic radiosurgery (SRS) are alternative treatment options.

Methods And Materials: Differences between frame-based and CBCT-defined stereotactic space after image co-registration were reviewed for 529 patients. Treatment planning system reported the information about the shifts in X, Y, and Z coordinates of the center of the stereotactic space (i.
