Abstract:ObjectiveTo analyze the usage and effect of Bromocriptine treating pituitary prolactinoma.Methods47 patients with pituitary prolactinoma treated from June 2014 to June 2016 were selected as the subjects.Among them,there were 27 patients with pituitary microadenoma(tumor diameter≤10 mm),20 patients with pituitary macroadenoma(tumor diameter>10 mm);there were 5 cases with 25 μg/L≤PRL<100 μg/L,22 cases with 100 μg/L≤PRL<200 μg/L,20 cases with PRL≥200 μg/L.After the patients were diagnosed,they are treated with Bromocriptine immediately.Serum prolactin level was regularly reviewed and pituitary enhanced MRI scan was conducted.PRL level and tumor size change were analyzed before and after treatment and the adverse reactions during the period of medication were monitored,and the treatment plan was adjusted in time.ResultsAfter Bromocriptine treatment,3 patients had severe adverse reactions and were replaced with Cabergoline.Among 44 patients who continued to take Bromocriptine medication,the symptom improvement rate was 70.5%.There was no significant difference in the therapeutic effect between different tumor size and different PRL level(P>0.05).The changes of tumor diameter before and after treatment were statistically significant(P<0.05).36.2%(17 patients)of patients in the medication had varying degrees of adverse reactions,the majority could be gradually tolerated.ConclusionBromocriptine has a significant therapeutic effect on hyperprolactinemia and tumor size in patients with pituitary prolactinoma,but there are several adverse reactions during treatment,and the therapeutic dose should be individualized.Patients with ineffective treatment should be preferred to replace the other dopamine receptor agonists.
