[Surgical treatment of pituitary adenomas in childhood and adolescence]

Objective: To investigate the clinical characteristics and treatment of pituitary adenomas of childhood and adolescence. Methods: Thisarticle was a retrospective study of 140 pituitary adenomas of childhood and adolescence that was admitted into Peking Union Medical College Hospital from December 1987 to December 2014, whose clinical manifestations, hormone secretions, images, pathological types, surgical complications and follow-ups were studied. Results: A total of 58 (41.4%) males and 82 females (58.6%) were included, whose mean age was 12.5 years old (age range from 7 to 18). As for the type of tumors, ACTH adenoma, PRL adenoma, GH adenoma, non-functional adenoma and multiple-secreting adenoma accounted for 35.7%, 25.7%, 12.2%, 25.7% and 0.7%, respectively. Microadenoma accounted for 33.6% of total patients, while macroadenoma and giant adenoma accounted for 60.0% and 6.4% respectively. 19.3% of adenomas in our study wereinvasive. Transsphenoidal approach surgery was commonly used and accounted for 97.9% of cases in our study, 2 of which used intraoperative navigation assistance. Total resection was achieved in 93.6% of patients, and the rest achieved subtotal resection. 108 (77.1%) patients got full term follow-up until 1 year after surgery, and tumor recurred in 14 patients (13.0%). Conclusions: ACTH-secreting adenoma is the most common pituitary adenoma in childhood and adolescence which need surgical treatment. Transsphenoidal approach surgery is the most commonly used surgical procedure. The recurrence rate is about 13%, and the patients need regular examination of pituitary hormones and image study to confirm the recurrence.
