Abstract:
Objective To explore the clinical features of the patients with prolactinoma and changes of pituitary function before and after surgery.Methods The clinical data of 72 patients with prolactinoma admit-ted and operatively treated in the neurosurgery department of the Second Hospital of Lanzhou University from June 2018 to January 2023 were analyzed retrospectively and their clinical characteristics and change character-istics of pituitary function before and after surgery were summarized.Results (1) Most of the patients with prolactinoma included in this study were macroadenomas,and its clinical manifestations were mainly tumor compression symptoms such as headache and vision diminution;(2) there was a statistically significant differ-ence in tumor invasiveness between the patients with preoperative PRL≥200.000 ng/mL and those with pre-operative PRL<200.000 ng/mL (P<0.05).(3) The PRL level of prolactinoma after surgical treatment in the patients with prolactinoma was significantly decreased compared to preoperative level,and the difference was statistically significant (P<0.05).(4) Among 72 patients,44 patients already had hypopituitarism before surgery,the pituitary function in 2 cases returned to normal,15 cases of hypopituitarism were newly increased and there were 57 cases of postoperative hypopituitarism.Preoperative hypopituitarism was positively correla-ted with postoperative hypopituitarism (r=0.433,P<0.05).By the logistic multifactorial regression analy-sis,the tumor maximal diameter was a risk factor for hypopituitarism occurrence before and after surgery (P<0.05),and the tumor invasiveness was a risk factor for postoperative hypopituitarism (P<0.05),where-as the BMI and PRL level,age,gender,and whether or not pituitary apoplexy occurring had no relationship with hypopituitarism (P>0.05).(5) The gonadal axis was the most common hypofunction in uniaxial sys-tem,and gonadal+thyroid axis was the most common biaxial involvement.Conclusion The surgical treat-ment in the patients with prolactinoma is effective for relieving tumor mass occupation and improving hyperp-rolactinemia.The pituitary function should be fully evaluated before and after surgery.For the patients with hypopituitarism occurrence,the hormone replacement therapy should be given in time,and at the same time the hormonal changes should be closely monitored.
