    Abstract:
    OBJECTIVE: To analyze the transsphenoidal microsurgical results of non-invasive prolactinomas, in order to provide reference for their treatment choice. METHODS: To review the transsphenoidal microsurgical results of 234 non-invasive prolactinomas treated in our department in recent 10 years, and to analyze the prognostic factors. There were 18 males and 216 females, aged between 13 and 58 years, averaged (31.1 +/- 8.5) years. The course ranged from half a month to 20 years, averaged (47.3 +/- 44.9) months. The preoperative serum PRL level ranged between 41 and 8406 ng/ml, averaged (400.5 +/- 888.0) ng/ml, with a median of 164.1 ng/ml. The primary symptoms were amenorrhea, galactorrhea and/or infertility in 211 cases. The tumor size was small (< 1 cm) in 100, large (> or = 1 cm) in 116 and giant (> or = 3 cm) in 18 cases. All the patients received transsphenoidal microsurgery and were followed-up for 12 to 132 months, averaged (43.8 +/- 35.0) months. RESULTS: There was no mortality. One hundred and twenty-seven (54.3%) cases had transient postoperative imbalance of water and electrolytes. One hundred and eighty-eight cases (80.3%) were cured, 12 (5.1%) experienced clinical remission, 20 (8.5%) were improved, and 14 (6.0%) were ineffective. The male patient, the giant prolactinomas and those with higher preoperative serum PRL level had a relative poor postoperative prognosis. While the other factors had no influence on prognosis, including the course, preoperative bromocriptine intake, tumor texture, tumor apoplexy and intraoperative descending extent of the diaphragm of sella. The overall operative expense for transsphenoidal microsurgery ranged from 8323.8 to 22898.5 yuan, averaged (12912.0 +/- 2361.2) yuan. CONCLUSIONS: Transsphenoidal microsurgery may be chosen as the primary therapy for non-invasive prolactinomas, with the purposes of therapeutical efficacy, facilitating the patients, re-establishing the patients' self-confidence and reducing the overall expense.
