ABSTRACT
OBJECTIVE:
There is a paucity of data describing long-term outcomes of paediatric patients with pituitary adenoma. In this report, we describe clinical features, treatment and outcomes of a paediatric cohort.DESIGN:
Retrospective cohort study. PATIENTS Twenty-four white Caucasian patients aged <16 years from a single tertiary care centre in the United Kingdom at diagnosis followed for (median, range) 3.3, 0.7-8.4 years. MEASUREMENTS Clinical and radiological data at diagnosis and follow-up.RESULTS:
Thirteen patients had prolactinomas (54.1%, age 15.2 years, 13.2-15.8 years; all females), including ten macroadenomas (11.0-35.0 mm). Patients presented with menstrual disorders (91%), headache (46%), galactorrhoea (46%) and obesity (body mass index [BMI] SDS > 2) (38%). Ten patients with prolactinoma were treated with dopamine agonist alone, 3 also required surgery and 2 patients, cabergoline, surgery plus radiotherapy. Five patients had Cushing's disease (20.8%, age 14.0, 4.0-15.7 years; 2 female), including one macroadenoma (24 mm). Patients presented with obesity (100%), short stature (60%) and headache (40%). Transsphenoidal resection resulted in biochemical cure (09.00 cortisol < 50 nmol/L). Two patients relapsed 3- and 6 years following surgery, requiring radiotherapy. One patient also required bilateral adrenalectomy. Six patients had nonfunctioning pituitary adenoma (25.0%, age 15.8, 12.5-16.0 years; 2 female), including two macroadenomas (20.0-53.0 mm). Patients presented with obesity (67%), visual field defects (50%) and headache (50%). Four required surgical resections; two recurred following surgery and required radiotherapy. On latest follow-up; 13 (54.1%) patients were obese (BMI 3.09 SDS; range 2.05-3.73 SDS).CONCLUSION:
Obesity is common at diagnosis of pituitary adenoma in childhood and may persist despite successful treatment. Adenomas were larger, more resistant to treatment, and more likely to recur than in adult populations.Key words
