OBJECTIVE: To investigate outcomes and identified risk factors affecting cure and intraoperative cerebrospinal fluid leak after transsphenoidal surgery using a new classification for growth hormone-secreting pituitary adenoma associated with empty sella.
METHODS: In this retrospective cohort study, 51 patients enrolled from January 2010 to June 2016 were categorized into 3 groups using a new classification scheme: grade A, whole tumor occupation area beneath a horizontal line drawn along the lowest level of empty sella; grade B, tumor occupation area that crossed the horizontal line on 1 side; and grade C, tumor occupation area that crossed the horizontal line on 2 sides. Clinical data were collected and analyzed.
RESULTS: Cure rate for grade A patients (88.24%; 15/17) was significantly higher than cure rate for grade B (55.00%; 11/20) and grade C (50.00%; 7/14) patients. Occurrence of cerebrospinal fluid leaks in grade C patients (35.71%; 5/14) was higher than in grade A patients (5.88%; 1/17). Logistic regression analysis indicated that risk factors affecting cure included large maximum tumor diameter (P = 0.009, odds ratio [OR] = 1.222), high preoperative fasting growth hormone level (P = 0.031, OR = 1.088), and high classification (P = 0.017, OR = 4.485). Risk factor affecting intraoperative cerebrospinal fluid leak was high classification (P = 0.039, OR = 3.580).
CONCLUSIONS: Transsphenoidal surgery is the current optimal treatment strategy. Empty sella increases the difficulty of surgery with a higher incidence of complications. The new classification scheme was better for predicting the surgical outcome for this disease.
