Context: Treatment of Newly Diagnosed Childhood Craniopharyngioma

It may be possible to remove all visible tumor and achieve long-term disease control.[2-4][Level of evidence C1] A 5-year progression-free survival (PFS) rate of about 65% has been reported.[5] Reported recurrence rates range from less than 10% to nearly 50%.[6,7] Gross-total resection is often technically challenging because the tumor is surrounded by vital structures, including the optic nerves and chiasm, the carotid artery and its branches, the pituitary and hypothalamus, and the third cranial nerve. These structures may limit the ability to remove the entire tumor. Conservative surgical approaches are often used to preserve functional and quality-of-life outcomes.[8,9][Level of evidence C1]

Many surgical approaches have been described, and the choice is determined by tumor size, location, extension, and the patient's baseline signs and symptoms of disease. Surgical approaches include the following:

Craniotomy: As noted above, gross-total resection may be technically challenging because the tumor is surrounded by vital structures. The surgeon often has a limited view of the hypothalamic and sellar regions, and portions of the mass may remain after surgery, accounting for some recurrences. An understanding of the complex variations in how the tumors grow anatomically may help facilitate gross-total resection.[10] Nonetheless, almost all craniopharyngiomas attach to the pituitary stalk. Of the patients who undergo complete resection, virtually all will require lifelong pituitary hormone replacement with multiple medications.[3,11]

Transsphenoidal approach: A transsphenoidal approach has been proven possible in patients of all ages and for tumors of various sizes localized within the sella.[12]; [13][Level of evidence C1] The development of expanded endonasal techniques with endoscopic visualization has allowed increased use of this approach, even for sizeable childhood tumors, which is similar to the experience in adults.[14] A complete resection can be obtained using this approach, with associated complications of panhypopituitarism and the risk of cerebrospinal fluid leaks.[15,16] When an endonasal approach is not possible, a craniotomy is required.

Blindness.

Seizures.

Spinal fluid leak.

False aneurysms.

Difficulty with eye movements.

Death from intraoperative hemorrhage, hypothalamic damage, or stroke (rare).

If the surgeon indicates that the tumor was not completely removed or if postoperative imaging reveals residual craniopharyngioma, radiation therapy may be recommended to prevent early progression.[19][Level of evidence C2] For more information, see the Subtotal Resection With Radiation Therapy section.

Routine surveillance using magnetic resonance imaging is performed for several years after complete resection because of the possibility of tumor recurrence.
