Abstract
Pituitary adenomas are rare in children and young people under the age of 19 (hereafter referred to as CYP) but they pose some different diagnostic and management challenges in this age group than in adults. These rare neoplasms can disrupt maturational, visual, intellectual and developmental processes and, in CYP, they tend to have more occult presentation, aggressive behaviour and are more likely to have a genetic basis than in adults. Through standardized AGREE II methodology, literature review and Delphi consensus, a multidisciplinary expert group developed 74 pragmatic management recommendations aimed at optimizing care for CYP in the first-ever comprehensive consensus guideline to cover the care of CYP with pituitary adenoma. Part 2 of this consensus guideline details 57 recommendations for paediatric patients with prolactinomas, Cushing disease, growth hormone excess causing gigantism and acromegaly, clinically non-functioning adenomas, and the rare TSHomas. Compared with adult patients with pituitary adenomas, we highlight that, in the CYP group, there is a greater proportion of functioning tumours, including macroprolactinomas, greater likelihood of underlying genetic disease, more corticotrophinomas in boys aged under 10 years than in girls and difficulty of peri-pubertal diagnosis of growth hormone excess. Collaboration with pituitary specialists caring for adult patients, as part of commissioned and centralized multidisciplinary teams, is key for optimizing management, transition and lifelong care and facilitates the collection of health-related quality of survival outcomes of novel medical, surgical and radiotherapeutic treatments, which are currently largely missing.

Abstract
Introduction Usually, prolactinomas are treated with dopamine agonists (DA). Surgery is considered an option when the patient cannot bear or does not respond positively to DA therapy. Aim This study aims to determine the early and late outcomes of surgery, with particular emphasis on developing prognostic factors for surgical treatment and analyzing risk factors affecting the recurrence of hyperprolactinemia and prolactinoma. Material and methods This retrospective study was conducted at the Feofaniya Clinical Hospital of the State Administration of Affairs (Kyiv, Ukraine), evaluating 109 patients' records from 2009 to 2019. The main patients' inclusion criteria were: serum prolactin (PRL) level of more than 100 ng/ml, presence of pituitary adenoma (PA) on MRI, histologically approved PA by microscopy. According to the size of the prolactin-secreting PA (PSPAs) the selected 109 patients were divided into two groups: micro- (≤10 mm, n = 75) and macroadenoma group (10-40 mm, n = 34). Results 1 month after the operation, PRL levels decreased by 87% (p < 0.001), 12 months-by 93% (p < 0.001). After receiving surgery and DA therapy for 12 months 77.1% of patients achieved biochemical remission. Out of the total number of patients observed, 15.6% (n = 17) had a Knosp score greater than 3. Additionally, in the macroadenoma group, the percentage of patients with a Knosp score greater than 3 was 41,2%, which was significantly higher as compared to the microadenoma group (4%, p < 0.001). In patients with microadenomas a weak reverse correlation between patients' age (r = -0.258, p < 0.026) and positive with tumor size (r = 0.251, p < 0.030) was revealed. In the macroadenoma group significant association was found only between preoperative serum PRL level and tumor size (r = 0.412, p < 0.016). The preoperative PRL can be used as a diagnostic marker for lack of early biochemical remission in patients with PSPAs with diagnostic accuracy 66.9%. Conclusions This study found that primary transsphenoidal surgery is an effective treatment in reaching PRL level control in patients with both micro- and macroprolactinomas. The correct and thorough selection of candidates for surgery is crucial to achieve postoperative serum PRL normalization in the vast majority of patients.

Abstract
Pituitary adenomas are benign tumors of the anterior portion of the pituitary gland (adenohypophysis), representing the 25% of all the tumor alterations. Pituitary adenomas are classified by the type of hormone secreted, cellularity, size, and structural alterations by the hormonal segregation. The diagnosis consists on the histopathological identification of cell types and the image-guided by magnetic resonance or tomography; the treatment can be both pharmacological and surgical. Metabolic Syndrome is the set of clinical conditions that increase the risk of cardiovascular diseases with an estimated prevalence of 25% worldwide. The alterations of metabolic syndrome are obesity, hypertension, dyslipidemia, insulin resistance, and diabetes mellitus type II. Pituitary adenomas and metabolic syndrome have an important relationship, hormone-secreting by pituitary adenomas affects a myriad of signaling pathways, which allows a favorable environment for the appearance of the metabolic syndrome. Moreover, patients with pituitary adenomas are shown to have an improvement in metabolic parameters after the medical/surgical treatment. The objective of this review is to explore the possible mechanisms through which PAs contributes to MetSx.

Endoscopic endonasal surgery for prolactinomas: prognostic factors for disease control and management of persistent disease. Neurosurg Rev 2023; 46:295.

Abstract
Only a limited number of studies have focused on the results of the Endoscopic Endonasal Approach (EEA) for treatment of prolactinomas. We sought to assess the effectiveness of EEA for prolactinoma surgery, identify factors for disease remission, and present our approach for the management of persistent disease. Forty-seven prolactinomas operated over 10 years, with a mean follow-up of 59.9 months, were included. The primary endpoints were early disease remission and remission at last follow-up. Resistance/intolerance to DA were surgical indications in 76.7%. Disease remission was achieved in 80% of microprolactinomas and 100% of microprolactinomas enclosed by the pituitary. Early disease remission was correlated with female gender (p=0.03), lower preoperative PRL levels (p=0.014), microadenoma (p=0.001), lack of radiological hemorrhage (p=0.001), absence of cavernous sinus (CS) invasion (p<0.001), and extent of resection (EOR) (p<0.001). Persistent disease was reported in 48.9% of patients, with 47% of them achieving remission at last follow-up with DA therapy alone. Repeat EEA and/or radiotherapy were utilized in 6 patients, with 66.7% achieving remission. Last follow-up remission was achieved in 76.6%, with symptomatic improvement in 95.8%. Factors predicting last follow-up remission were no previous operation (p=0.001), absence of CS invasion (p=0.01), and EOR (p<0.001). Surgery is effective for disease control in microprolactinomas. In giant and invasive tumors, it may significantly reduce the tumor volume. A multidisciplinary approach may lead to long-term disease control in three-quarters of patients, with symptomatic improvement in an even greater proportion.

Abstract
PURPOSE Pituitary adenomas are the most common sellar tumors, and may cause adverse outcomes in terms of morbidity and mortality if left untreated or if diagnosis is delayed. No data exists on the prevalence, characteristics, and prognosis of pituitary adenomas in Thailand. The systematic registration of clinical characteristics may improve patient care and prognosis for this disease in Thailand. METHODS This was a retrospective study conducted in 11 academic referral centers. All patients diagnosed with pituitary adenomas during the 2011---2014 period were enrolled in the study. The information was correlated with two national databases. RESULTS A total of 1,283 pituitary adenoma patients were identified. The adenomas were: non-functioning 50.1%, prolactinoma 29.4%, acromegaly 14.7%, Cushing disease 3.8%, gonadotropin-producing tumor 1.0%, TSH-secreting tumor 0.6%. The mean age was 49.2±15.2 years. Sixty-three percent of patients were female. Most common complaint was visual impairment (27.7%). The average size of the tumor was 22.2±16.1 mm. Fifty-nine percent of patients underwent surgery. Median follow-up was 27.4 months (0-24 years). After treatment, 72.4% improved, and 10.4% were cured. Overall results of treatment in non-functioning adenoma, prolactinoma (medically treated), acromegaly, Cushing, TSH, gonadotropin producing adenoma were: improved/cured in 81/5.5, 86/5.7, 55.9/30, 54.2/31.2, 85.7/14.3, 69.2/15.4% respectively. CONCLUSION Pituitary adenomas in academic centers in Thailand were found predominantly in female in the 4th decade of life. After treatment 72.4% of patients improved and 10% had full recovery. A health promotion system aimed to improve patient and physician recognition and physician expertise may improve the prognosis of these diseases.

Abstract
PURPOSE Treatment with dopamine agonists (DAs) has been the first-line standard treatment for prolactinoma, and surgery has been reserved for drug intolerance and resistance for several decades. We evaluated whether surgery plays a primary role in prolactinoma management. MATERIALS AND METHODS We conducted a retrospective study of 210 prolactinoma patients who had received surgical treatment at our institution. We analyzed the treatment outcomes according to tumor extent, sex, and preoperative DA medication. RESULTS Overall hormonal remission was achieved in 164 patients (78.1%), and complete removal was achieved in 194 patients (92.4%). When the tumors were completely removed, the remission rate increased to 84.5%. Anterior pituitary function was normalized or improved in 94.6% of patients, whereas only 4.1% of patients showed worsening of hormone control. Hormonal remission was higher in patients who had not received DA preoperatively than in those who had received preoperative DA treatment. Smaller tumor size (<1 cm), no invasion into the cavernous sinus, and female sex were predictors of good surgical outcomes. CONCLUSION Although DAs remain the first-line standard treatment for prolactinomas, surgery can be an excellent option and should be considered as an alternative primary treatment modality when patients are predicted to achieve a good surgical outcome.

Abstract
BACKGROUND Transsphenoidal surgery is one of the important treatment options in the management of prolactinomas; however, complete resection of the tumor does not always lead to endocrinological remission. While many studies have investigated preoperative factors associated with surgical outcome, little has been known about the relationship between postoperative factors and long-term surgical outcomes; moreover, there is no consistency in results. The aim of this study was to demonstrate the reliability of immediate postoperative prolactin levels as predictors of long-term outcomes. METHODS A total of 105 female patients who underwent complete removal of their histologically confirmed prolactinomas were included, and their medical records were retrospectively reviewed. To evaluate the predictability of immediate postoperative prolactin levels for long-term remission, prolactin levels were measured at 2, 6, 12, 18, 24, 48, and 72 h after surgery. RESULTS From the 105 included patients, 95 (90.5%) and 10 (9.5%) belonged to the remission and non-remission groups, respectively. A significant difference was observed in the prolactin level measured 6 h after surgery between the remission and non-remission groups, and this difference stayed apparent until 72 h after surgery. We derived a cut-off value for every postoperative time point that showed a significant relationship with disease remission. CONCLUSION Our study suggests that immediate postoperative measurement of prolactin levels is a reliable predictor of long-term remission and can contribute to early identification of patients who require adjuvant treatment after surgery.

Abstract
OBJECTIVE To investigate the initial and long-term remission rates, factors related to remission, secondary treatments, and outcomes for patients with prolactinoma who underwent endoscopic transsphenoidal surgery (ETSS). METHODS The medical files of the 45 prolactinoma patients who underwent ETSS between 2015 and 2022 were retrospectively reviewed. Relevant demographic and clinical data were obtained. RESULTS Twenty-one (46.7%) patients were female. The median age of patients at ETSS was 35 (interquartile range, 22.5-50) years. The median clinical follow-up of patients was 28 (interquartile range 12-44) months. The initial surgical remission rate was 60%. Recurrence was detected in 7 patients (25.9%). Postoperative dopamine agonists were used in 25 patients, radiosurgery in 2, and second ETSS in 4 patients. After these secondary treatments, the long-term biochemical remission rate was 91.1%. The factors associated with failure in surgical remission are: male gender, older age, higher tumor size, advanced Knosp and Hardy stage, and elevated prolactin level at diagnosis. A prolactin level of <19 ng/mL in the first postoperative week predicted surgical remission with a sensitivity of 77.8% and a specificity of 70.6% in patients who received preoperative dopamine agonist treatment. CONCLUSIONS In macro adenomas and/or giant adenomas with cavernous sinus invasion, and significant suprasellar extension, which constitutes the difficult part of prolactinoma treatment, neither surgery nor medical treatment alone may be effective enough. Both treatment modalities should be carried out together by a team of neurosurgery and endocrinology in the management of these patients.

Abstract
PURPOSE Dopamine agonists (DA) are the gold-standard for prolactinoma and hyperprolactinemia treatment. Intolerance to DA leading to drug drop out occurs in 3 to 12% of cases. We provide here a review of published data about DA intolerance and present a case report concerning the use of intravaginal cabergoline. METHODS We review the literature on the definition, the pathogenesis, frequency and management of DA intolerance. In addition, the review provides strategies to enhance tolerability and avoid precocious clinical treatment withdrawal. RESULTS Cabergoline is often cited as the most tolerable DA and its side effects tend to ameliorate within days to weeks. Restarting the same drug at a lower dose or switching to another DA can be used in cases of intolerance. The vaginal route can be tried specifically if there are gastrointestinal side effects in the oral administration. Symptomatic treatment could be attempted, although mainly based on a strategy used in other diseases. CONCLUSIONS Due to limited data, no guidelines have been developed for the management of intolerance in DA treatment. The most frequent management is to perform transsphenoidal surgery. Nevertheless, this manuscript provides data derived from published literature and expert opinion, suggesting new approaches to this clinical issue.

Uzuner A, Yilmaz E, Caklili M, Selek A, Aydemir F, Cabuk B, Anik I, Ceylan S. Endoscopic Transnasal Approach for Microprolactinomas with Experience of 105 Cases in a Single Center: Paradigmal Shift for Conventional Medical Therapy. World Neurosurg 2023; 170:e858-e867. [PMID: 36481446 DOI: 10.1016/j.wneu.2022.12.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 11/30/2022] [Accepted: 12/01/2022] [Indexed: 12/12/2022]
Abstract
OBJECTIVE The classically recommended first-line therapy for microprolactinomas is medical therapy. In the presence of drug resistance and intolerance after the use of dopamine agonists or when the patients prefer surgery instead of medication, surgical treatment is considered as second-line treatment. The high hormonal remission and low complication rates after surgery for microprolactinomas suggest that the surgical outcome of endoscopic surgeries may be better than medical therapy in well-selected patients. This study reports a large series of patients with microprolactinoma treated by endoscopic transnasal approach and evaluates the efficiency of surgical treatment. METHODS Our study is a retrospective cohort analysis of patients with microprolactinoma operated on by an endoscopic transnasal approach between August 1997 and February 2022 by an experienced pituitary surgeon in a single tertiary center. Inclusion criteria for microprolactinoma were based on increased prolactin levels, microadenoma (<10 mm in diameter) on pituitary magnetic resonance imaging, and histopathologically verified lactotroph adenoma. RESULTS The mean follow-up was 74.90 months (range, 6-207). The postoperative day 1 remission rate was 85.7% and the long-term remission rate was 74.3%. The long-term remission rates of the patients in the preference group were significantly higher than those of the patients in the resistant or intolerance group (P = 0.002). Patients who used dopamine agonists for more than 3 years had a lower remission rate compared with patients who used dopamine agonists for a shorter period or who did not use it (P = 0.01). The surgical complication rate was 4.76%. CONCLUSIONS According to our findings, endoscopic transnasal surgery performed by an experienced neurosurgeon in well-selected patients with microprolactinoma can be offered with cure rates superior to medical therapy and may be an alternative first-line treatment option to dopamine agonists.

Abstract
INTRODUCTION Treatment of prolactinomas with dopamine agonists has been the established first-line treatment option for many years, with surgery reserved for refractory cases or medication intolerance. This approach may not be the best option in many cases. AREAS COVERED Review of the epidemiology, biology, and treatment options available for prolactinomas, including best available data on outcomes, costs, and morbidities for each therapy. These data are then used to propose a 'surgery-first' treatment approach for a subset of prolactinomas as an alternative to primary medical management. EXPERT OPINION Based on the available data, there is a strong rationale that transsphenoidal surgery should be considered a first-line treatment option for both micro- and macro-prolactinomas that do not demonstrate high grade cavernous sinus invasion on MRI imaging, with dopamine agonists administered as a secondary therapy for tumors not in remission following surgery, and for giant tumors. This 'surgery-first' approach assumes the availability of skilled and experienced pituitary surgeons to ensure optimal outcomes. This approach should result in high cure rates and reduced DA requirements for patients not cured from initial surgery. Further, it will reduce medical costs over a patient's lifetime and the chronic morbidities associated with protracted dopamine agonist usage.

Extra-Pseudocapsular Transsphenoidal Surgery for Microprolactinoma in Women. J Clin Med 2022; 11:jcm11133920. [PMID: 35807204 PMCID: PMC9267792 DOI: 10.3390/jcm11133920] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 06/20/2022] [Accepted: 06/30/2022] [Indexed: 11/25/2022] Open
Abstract
A recall for histological pseudocapsule (PS) and reappraisal of transsphenoidal surgery (TSS) as a viable alternative to dopamine agonists in the treatment algorithm of prolactinomas are getting vibrant. We hope to investigate the effectiveness and risks of extra-pseudocapsular transsphenoidal surgery (EPTSS) for young women with microprolactinoma, and to look into the factors that influenced remission and recurrence, and thus to figure out the possible indication shift for primary TSS. We proposed a new classification method of microprolactinoma based on the relationship between tumor and pituitary position, which can be divided into hypo-pituitary, para-pituitary and supra-pituitary groups. We retrospectively analyzed 133 patients of women (<50 yr) with microprolactinoma (≤10 mm) who underwent EPTSS in a tertiary center. PS were identified in 113 (84.96%) microadenomas intraoperatively. The long-term surgical cure rate was 88.2%, and the comprehensive remission rate was 95.8% in total. There was no severe or permanent complication, and the surgical morbidity rate was 4.5%. The recurrence rate with over 5 years of follow-up was 9.2%, and a lot lower for the tumors in the complete PS group (0) and hypo-pituitary group (2.1%). Use of the extra-pseudocapsule dissection in microprolactinoma resulted in a good chance of increasing the surgical remission without increasing the risk of CSF leakage or endocrine deficits. First-line EPTSS may offer a greater opportunity of long-term cure for young female patients with microprolactinoma of hypo-pituitary located and Knosp grade 0-II.

Abstract
Abstract
Objectives Initial therapy for the management of prolactinomas has long been maintained to be medical, consisting of a dopamine agonist. These therapies may have troublesome side effects, and some prolactinomas are resistant to medical therapy regarding lowering prolactin levels or shrinking the tumor. These issues have revived interest in surgery for prolactin-secreting adenomas as an early therapeutic option. We report our analysis of surgery for prolactin microadenomas in women, using the transsphenoidal endoscopic approach.
Design We reviewed a contemporary series of 33 women (mean age = 31.8 years) with microprolactinomas who underwent early surgical intervention, which was a three-dimensional transnasal transsphenoidal endoscopic operation.
Setting The study was conducted at a tertiary academic referral center for pituitary tumors.
Main Outcome Measures Preoperative and postoperative prolactin.
Results Overall, 28 patients had received preoperative dopamine agonists, 24 of these experienced a variety of drug-related side effects, and 4 had tumors that were resistant to lowering prolactin or tumor shrinkage. Preoperative prolactin levels averaged 90.3 ng/mL (range = 30.7–175.8 ng/mL). We observed a 94% normalization rate in postoperative prolactin (mean = 10.08 ng/mL, range = 0.3–63.1 ng/mL). During the follow-up (mean = 33.9 months), five patients had elevated prolactin; four required reinitiation of medical therapy, two had surgical reexploration, and none received radiation therapy. Complications included syndrome of inappropriate antidiuretic hormone secretion (n = 3), transient diabetes insipidus (n = 1), postoperative epistaxis (n = 1), and fat graft site infection (n = 1).
Conclusion This review supports the consideration of transsphenoidal surgery as an early intervention for some women with prolactin-secreting microadenoma. Indications include significant side effects of medical therapy and tumors that do not respond to standard medical management.

Abstract
Background For prolactinoma patients, dopamine agonists (DAs) are indicated as the first-line treatment and surgery is an adjunctive choice. However, with the development of surgical technique and equipment, the effect of surgery has improved. The aim of this study was to assess the efficacy and safety of surgery versus DAs in patients with different types of prolactinomas. Methods A systematic search of literature using Web of Science, PubMed, Cochrane Library, and Clinical Trial databases was conducted until July 12, 2019. Prolactinoma patients treated with DAs (bromocriptine or cabergoline) or surgery (microscopic or endoscopic surgery) were included. Outcomes included the biochemical cure rate, recurrence rate, prolactin level, improvement rates of symptoms, and incidence rates of complications. A random-effects model was used to pool the extracted data. Qualitative comparisons were conducted instead of quantitative comparison. Results DAs were better than surgery in terms of the biochemical cure rate (0.78 versus 0.66), but surgery had a much lower recurrence rate (0.19 versus 0.57). Full advantages were not demonstrated in improvement rates of symptoms and incidence rates of complications with both treatment options. In microprolactinoma patients, the biochemical cure rate of endoscopic surgery was equal to the average cure rate of DAs (0.86 versus 0.86) and it surpassed the biochemical cure rate of bromocriptine (0.86 versus 0.76). In macroprolactinoma patients, endoscopic surgery was slightly higher than bromocriptine (0.66 versus 0.64) in terms of the biochemical cure rate. Conclusion For patients with clear indications or contraindications for surgery, choosing surgery or DAs accordingly is unequivocal. However, for patients with clinical equipoise, such as surgery, especially endoscopic surgery, in microprolactinoma and macroprolactinoma patients, we suggest that neurosurgeons and endocrinologists conduct high-quality clinical trials to address the clinical equipoise quantitatively.

Abstract
Prolactinomas are the most frequent pituitary adenomas. Prolactinoma may occur in different clinical settings and always require an individually tailored approach. This is the reason why a panel of Italian neuroendocrine experts was charged with the task to provide indications for the diagnostic and therapeutic approaches that can be easily applied in different contexts. The document provides 15 recommendations for diagnosis and 54 recommendations for treatment, issued according to the GRADE system. The level of agreement among panel members was formally evaluated by RAND-UCLA methodology. In the last century, prolactinomas represented the paradigm of pituitary tumors for which the development of highly effective drugs obtained the best results, allowing to avoid neurosurgery in most cases. The impressive improvement of neurosurgical endoscopic techniques allows a far better definition of the tumoral tissue during surgery and the remission of endocrine symptoms in many patients with pituitary tumors. Consequently, this refinement of neurosurgery is changing the therapeutic strategy in prolactinomas, allowing the definitive cure of some patients with permanent discontinuation of medical therapy.

Abstract
BACKGROUND Dopaminergic agonists (DA) are the first-line treatment in lactotroph pituitary tumor but treatment usually needs to be life-long. After surgical transphenoid resection, remission rates range from 60% to 90%, with low morbidity. OBJECTIVE The objective was to evaluate outcome of surgical treatment of selected non-invasive prolactinoma, and to identify factors associated with long-term remission. METHOD Early postoperative (3 months) and last follow-up data for non-invasive lactotroph tumors operated on in intention-to-cure in our center, between 2008 and 2017 were retrospectively reviewed: prolactin (PRL) level, DA treatment, pituitary function, and MRI data. Remission was defined as PRL plasma level below the upper limit of normal without DA treatment. RESULTS Fifty-three of the 60 patients (32 of the 33 microadenomas) were in remission at 3 months and 46 (28/33 microadenomas) at last follow-up 22.7 months (range, 1.1-126.5 months) after surgery. Five-year recurrence-free survival was 77.5% [65.8-91.2]. Male gender, larger tumor size at diagnosis and before surgery and higher plasma PRL level at diagnosis were all significantly associated with lower remission rates on univariate analysis. Transient diabetes insipidus and hyponatremia occurred in 2 and 5 patients respectively. One case of isolated thyrotroph insufficiency was observed. During follow-up, 13 women became pregnant (12 spontaneously). CONCLUSION This cohort confirmed the high remission rate of lactotroph tumors after surgery in a selected population, with limited morbidity, and conserved pituitary function in almost all cases.

Abstract
PURPOSE Dopamine agonists (DA) comprise first-line treatment for prolactinomas. However, some patients show no response to DA and are considered resistant. In this study, we retrospectively analyzed the outcomes of DA-resistant prolactinoma patients after transsphenoidal surgery (TSS). METHODS A total of 94 consecutive patients with DA-resistant prolactinomas who underwent TSS were retrospectively enrolled in the present study. Early postoperative remission rate, prolactin (PRL) levels, and recurrence rate were analyzed. RESULTS Of 94 DA-resistant patients, 47 (50%) achieved early remission 1 week post-surgery, including 41.18% of macroprolactinoma patients and 73.08% of microprolactinoma patients. PRL levels on the first postoperative day were significantly lower than preoperative PRL levels (p < 0.001). Total resection rate in macro- and microprolactinomas were, respectively, 75 and 96.15%. A recurrence of hyperprolactinemia and tumor was, respectively, found in 31.91 and 19.15% of patients with a follow-up of 39.53 ± 2.172 months (range 3-86). A higher hyperprolactinemia recurrence was observed in patients with invasive prolactinomas (p = 0.021) or preoperative PRL levels ≥ 200 ng/ml (p = 0.029). Univariate logistic regression indicated that larger maximum tumor diameter (p = 0.045), invasive prolactinomas (p = 0.002), and absence of early postoperative remission (p = 0.004) were significant predictors of tumor recurrence. However, using multivariate stepwise logistic regression, only invasiveness and early postoperative remission remained significant. CONCLUSION Tumor invasiveness and preoperative PRL levels were significant predictors of hyperprolactinemia recurrence after TSS. For tumor recurrence, invasiveness and early postoperative remission were independent predictors.

Abstract
CONTEXT Although consensus guidelines recommend dopamine agonists (DAs) as the first-line approach in prolactinomas, some patients may opt instead for upfront surgery, with the goal of minimizing the need for continuation of DAs over the long term. While this approach can be recommended in selected patients with a microprolactinoma, the indication for upfront surgery in macroprolactinomas remains controversial, with limited long-term data in large cohorts. We aimed at elucidating whether first-line surgery is equally safe and effective for patients with micro- or macroprolactinomas not extending beyond the median carotid line (i.e., Knosp grade ≤ 1). METHODOLOGY Retrospective study of patients with prolactinomas Knosp grade ≤ 1 treated with upfront surgery. The primary endpoint was patients' dependence on DAs at last follow-up. The secondary endpoint was postoperative complications. Independent risk factors for long-term dependence on DAs were analyzed. RESULTS A microadenoma was noted in 45 patients (52%) and a macroadenoma in 41 (48%), with 17 (20%) harboring a Knosp grade 1 prolactinoma. Median follow-up was 80 months. First-line surgery resulted in long-term remission in 31 patients (72%) with a microprolactinoma and in 18 patients (45%) with a macroprolactinoma (p = 0.02). DA therapy was ultimately required in 11 patients (24%) with microadenomas vs. 20 (49%) with macroadenomas (p = 0.03). As for the latter, DA was required in 13 patients (76%) with Knosp grade 1 macroadenomas vs. 7 patients (29%) with Knosp grade 0 macroadenomas (p = 0.004). There was no mortality, and morbidity was minimal. Knosp grade 1 prolactinomas (OR 7.3, 95% CI 1.4-37.7, p = 0.02) but not adenoma size (i.e., macroprolactinomas) were an independent predictor of long-term dependence on DAs. CONCLUSIONS First-line surgery in patients with microprolactinomas or macroprolactinomas Knosp grade 0 resulted in a good chance of non-dependency on DA therapy. However, in patients with prolactinomas Knosp grade 1, first-line surgery cannot be recommended, as adjuvant DA therapy after surgery is required in the majority of them over the long term.

Abstract
PURPOSE Dopamine agonists (DAs) have long been the recommended first-line treatment for prolactinoma. Given the remarkable developments in surgical techniques, however, surgery is on the rise. We compared the treatment outcomes of patients with noninvasive prolactinomas receiving two different initial treatments (DAs and transsphenoidal surgery). METHODS We reviewed 745 patients with hyperprolactinemia or pituitary tumors treated from 2004 to 2020 at Chonnam National University Hwasun Hospital and identified 310 with prolactinomas. After selecting patients who had pituitary tumors with Knosp grade 0 to 1 with follow-up period over 1 year, 70 patients (29 who underwent surgery and 41 who received DAs as the initial treatment) were finally included for a comparative study. RESULTS The surgery group exhibited better outcomes in terms of DA-free remission and the structural response, although the tumor size was significantly larger than in the DA group. The groups exhibited comparable results in terms of symptom control and the biochemical response. Univariate and multivariate analyses indicated that surgery as the initial treatment modality provided significantly better clinical outcomes in terms of DA-free remission. In the surgery group, a postoperative prolactin level < 10 ng/mL was the only significant predictor of DA-free remission. CONCLUSIONS Transsphenoidal surgery showed comparable clinical outcomes in patients with prolactinomas, and low complication rates. The decision regarding the first-line treatment modality for non-invasive prolactinomas should be made on an individual basis.

Abstract
Context Surgical management of prolactinomas is an important treatment for patients intolerant of dopamine agonist therapy. However, predictors of postoperative outcomes remain unclear. Object While transsphenoidal surgical resection (TSSR) is important second-line therapy in prolactinoma patients, predictors of surgical cure and biochemical remission following TSSR remain sparse. Methods A retrospective review of prolactinoma patients undergoing TSSR at the USC Pituitary Center from 1995 to 2020 was conducted. Participants were categorized as surgical cure (normalization of serum prolactin without medical treatment), surgical noncure, biochemical control (prolactin normalization with or without adjuvant therapy), and nonbiochemical control. A systematic review of the outcomes of surgically managed prolactinomas was performed. Results The 40 female and 16 male participants had an average age of 35.6 years. Prior treatment included transsphenoidal resection (6, 11%) and dopamine agonist treatment (47, 84%). The 40 macroadenomas and 15 microadenomas exhibited suprasellar extension (24, 43%) and parasellar invasion (20, 36%). Fifteen (27%) were purely intrasellar. Gross total resection was achieved in 25 patients (45%) and subtotal in 26 (46%). Surgical cure was achieved in 25 patients (46%) and biochemical control in 35 (64%). Surgical cure was more likely in smaller, noninvasive tumors, those that were fully resected, and patients with lower preoperative (< 1000 ng/mL) and immediately postoperative (< 7.6 ng/mL) prolactin levels. Ten of 26 patients (38%) undergoing adjuvant therapy achieved biochemical control, which was less likely in men and those with higher preoperative prolactin or invasive tumors. Conclusion Surgical resection of prolactinomas is a safe procedure that, when offered judiciously, can achieve symptom and/or biochemical control in a majority of patients. A variety of predictors may be useful in advising patients on likelihood of postoperative remission.

Determinants of Surgical Remission in Prolactinomas: A Systematic Review and Meta-Analysis. World Neurosurg 2021; 154:e349-e369.

Abstract
OBJECTIVE Prolactin-secreting tumors respond well to medical management, with a few patients requiring surgery. We conducted a systematic review and meta-analysis to study the determinants of surgical remission in these tumors. METHODS We searched PubMed to identify eligible studies reporting postoperative remission in patients treated with transsphenoidal surgery for prolactinoma. Primary outcomes included postoperative remission, follow-up remission, and recurrence. Postoperative and follow-up remission were defined as normoprolactinemia at <1 year and >1 year after operation, respectively. Recurrence was defined as hyperprolactinemia after initial normalization of prolactin levels. Odds ratios (ORs) were calculated, stratified by radiologic size, tumor extension, and tumor invasion, and analyzed using a random-effects model meta-analysis. RESULTS Thirty-five studies were included. Macroadenomas were associated with lower rates of postoperative remission (OR, 0.20; 95% confidence interval [CI], 0.16-0.24) and lower rates of remission at follow-up (OR, 0.11; 95% CI, 0.053-0.22). Postoperative remission was less likely in tumors with extrasellar or suprasellar extension (OR, 0.16; 95% CI, 0.06-0.43) and tumors with cavernous sinus invasion (OR, 0.03; 95% CI, 0.01-0.13). Female gender and absence of preoperative dopamine agonist treatment were also associated with higher remission rates. Across the included studies, there was considerable heterogeneity in each primary outcome (postoperative remission, I2 = 94%; follow-up remission, I2 = 86%; recurrence, I2 = 68%). CONCLUSIONS Transsphenoidal surgery for prolactinomas may be particularly effective in small, noninvasive, treatment-naive tumors and may provide a viable first-line alternative to dopamine agonist therapy in such patients.

Abstract
Simple Summary Prolactinomas constitute a subgroup of pituitary adenomas for which there are several treatment options. Dopamine agonists (DA), since their introduction, have shown a strong efficacy both in the control of hyperprolactinemia and of the significant volumetric reduction of prolactinomas, leading, in some cases, to a definitive cure. Trans-sphenoidal surgery (TSS) has been traditionally confined to a failure of medical therapy, pituitary apoplexy with neurological worsening, and prolactinomas with wide cystic components. Moreover, the recent technical innovations introduced in TSS and increasing experience of surgeons have allowed to achieve better results, such as complete tumor resection with lower complication rates. On these grounds, the authors reviewed the extensive institutional Prolactinomas case series over the last 25 years to analyze the role of TSS in the management of Prolactinomas, particularly in terms of the cure rate. Abstract Background: Prolactinomas represent a unique challenge for endocrinologists and neurosurgeons. Considering recent innovations in surgical practice, the authors aimed to investigate the best management for prolactinomas. Methods: A retrospective, cross-sectional and monocentric study was designed. Consecutive patients affected by prolactinomas were enrolled if treated with a first-line treatment with a dopamine agonist (DA) or trans-sphenoidal surgery (TSS). Patients carried giant prolactinomas, and those with a follow-up <12 months were excluded. Results: Two hundred and fifty-nine patients were enrolled. The first treatment was DA for 140 patients and TS for 119 cases. One hundred and forty-six of 249 patients (58.6%) needed a second therapy. The mean follow-up was 102.2 months (12–438 months). Surgery highly impacted on the cure rate—in particular, in females (p = 0.0021) and in microprolactinomas (p = 0.0020). Considering the multivariate analysis, the female gender and surgical treatment in the course of the clinical history were the only independent positive predictors of a cure at the end of 5 years follow-up (p = 0.0016, p = 0.0005). The evaluation of serum prolactin (24 hours after TSS) revealed that 86.4% of patients with postoperative prolactin (PRL) ≤10 ng/mL were cured at the end of the follow-up (p < 0.0001). Conclusions: According to our experience, surgery allows a high cure rate of prolactinomas, particularly in females with microadenoma, with a good safety profile. TSS for prolactinomas should be considered as a concrete option, during the multidisciplinary evaluation, in centers of reference for pituitary diseases.

Utility of intraoperative ultrasonography for resection of pituitary adenomas: a comparative retrospective study. Acta Neurochir (Wien) 2021; 163:1725-1734.

Abstract
BACKGROUND The evolution of pituitary surgery has made it a safe and effective form of treatment; however, risks of inadequate tumor resection, cerebrospinal fluid (CSF) leak, pituitary dysfunction, and vascular injury still exist. The use of intraoperative ultrasonography (IOUS) in pituitary surgery has been well described. Recent advancements in ultrasound technology have allowed for expanded utility as described here. METHODS A retrospective review was performed between January 2016 and December 2019. One hundred thirty-eight patients (mean age 53.7 years, 47% females) were identified undergoing transsphenoidal surgery for pituitary tumors. Thirty-four patients had IOUS performed using a side-firing ultrasound probe, while 104 did not. Data was analyzed for preoperative (demographics, clinical, and radiographic features), perioperative (blood loss, operative time), and postoperative (complications, length of stay, hormone remission, and extent of resection) outcomes. RESULTS There were no significant differences in patient age, gender, tumor volume, Knosp grade, and hormone-secreting status between the two groups. Patients treated using IOUS had significantly higher rates of gross total resection (79% vs. 44%, p = 0.0008), shorter operative times (74 vs. 146 min, p < 0.0001), lower blood loss (119 vs. 284 cc, p < 0.0001), and hospital stays (2.9 vs. 4.2 days, p = 0.001). Overall complication rates were lower in the IOUS group compared to standard pituitary surgery but did not reach significance. CONCLUSIONS Recent improvements in ultrasound technology have allowed for miniaturization of probes capable of delivering high-resolution images. The use of IOUS in transsphenoidal pituitary surgery may significantly increase rates of gross total resection, while decreasing blood loss, hospital LOS, and operative time.

Abstract
OBJECTIVE Dopamine agonists (DAs) are recommended as the first-line treatment for prolactinomas; however, tumour recurrence after drug withdrawal remains a clinical problem. Recent studies have reported high remission rates via surgery in microprolactinomas. The aim of this systematic review and meta-analysis was to compare the clinical result of DA treatment with surgery as initial therapy in patients with treatment-naive microprolactinoma. METHODS A comprehensive literature search for studies and reports regarding microprolactinoma patients treated with DAs and/or surgery published between January 1970 and November 2020 was conducted using four electronic databases (PubMed, Embase, Google Scholar, and the Cochrane Library). Clinical treatment outcome was evaluated by the biochemical remission of serum prolactin level to normal after treatment. The I 2 statistic was used to quantify heterogeneity. Pooled data were analysed according to a random effect model. RESULTS Eighteen studies with 661 patients were included for analysis. The DA treatment group achieved a higher remission rate at ≥12 months follow-up (96% vs. 86%; P=0.019). Surgery showed a higher remission rate than the DA treatment group after the treatment withdrawal (78% vs. 44%; P=0.003). Patients with preoperative prolactin level of ≤200 ng/mL had a higher remission rate than patients with preoperative prolactin level of >200 ng/mL (92% vs. 40%; P=0.029). CONCLUSION Surgery showed a high remission rate in treatment-naive microprolactinoma patients after treatment withdrawal and may be an alternative first-line treatment strategy in addition to DAs, particularly in patients with a preoperative prolactin level of ≤200 ng/mL.

Abstract
Surgical experience is of paramount importance to reach therapeutic success and minimize operative complications. In the field of pituitary surgery, this led to the concept of Pituitary Center of Excellence (PTCOE) defined as a center where an interdisciplinary team works in collaboration and where surgeons can be trained appropriately to reach and keep excellence in daily practice. To review the literature to define the optimal referral population size to establish a PTCOE to optimize both training and specific field research. A review of the literature was performed about epidemiology. The time needed to observe 200 cases of PAs in a single PTCOE and to reach the minimal surgical experience threshold (MSET) was calculated for different referral population groups. The time needed to reach MSET decreased as population size increased. We defined a population as the optimal one to be served by a single PTCOE with a single dedicated neurosurgeon. PTCOEs should be established after an analysis of the referral population, number of cases suitable for surgical treatment and number of dedicated neurosurgeons.

Abstract
BACKGROUND Surgical resection of prolactinomas resistant to dopamine agonists is frequently incomplete due to fibrotic changes of the tumour under pharmacological therapy. In order to identify a subgroup of patients who may benefit from early surgery, we thought to investigate possible predictive factors of pharmacological resistance of prolactinomas to dopamine agonists. METHODS We retrospectively analyzed a database of a Belgian tertiary reference center for patients with pituitary tumours from 2014 to 2016. The groups of interest were patients with dopamine agonist responsive and resistant prolactinomas. The possible predictive factors, including MRI findings, endocrinological parameters, response of tumour and patient factors for dopamine agonist resistance were investigated. RESULTS We included 69 patients of whom 52 were women (75,4%) and 17 were men (24,6%). Rate of dopamine agonist resistance was 15.9%. We identified four significant predictors of dopamine agonist resistance: male gender, a large tumour volume, prolonged time to prolactin normalization and presence of a cystic, hemorrhagic and/or necrotic component. In addition, symptoms due to mass effect, high baseline prolactin level and a high contrast capture on MRI are factors that can be taken into consideration. CONCLUSION We identified predictive factors for pharmacological resistance and developed a scoring system for patient specific prediction of resistance to dopamine agonists. This scoring system may have impact on the timing and decision of surgery in prolactinoma patients after further prospective evaluation.

Abstract
BACKGROUND Current standard treatment of microprolactinomas is dopamine agonist therapy. As this drug treatment is lifelong in up to 80% of cases, many patients consult pituitary surgeons regarding a surgical alternative. OBJECTIVE To identify prognostic criteria for surgical remission, we reviewed outcomes of our series of microprolactinomas treated with endoscopic transsphenoidal surgery, with a special emphasis on magnetic resonance adenoma delineation and position. METHODS Our study cohort comprises a single center series of 60 patients operated for histopathologically verified magnetic resonance imaging unequivocally identifiable endosellar microprolactinoma between 2003 and 2017. In 31 patients the adenoma was enclosed by pituitary gland (group ENC), in 29 patients the adenoma was located lateral to the gland adherent to the medial cavernous sinus wall (group LAT). RESULTS After a mean follow-up of 37 mo (range 4-143 mo), remission rate was significantly higher in adenomas enclosed by pituitary gland (group ENC) than adenomas located lateral to the gland (group LAT), with 87% vs 45%, P = .01. Intraoperatively, 4 patients showed signs of invasiveness. Preoperative prolactin levels did not differ between the groups (mean 155 and 187 ng/ml in group ENC and LAT, respectively).A binary logistic regression model revealed that only the radiological criteria applied showed a significant correlation (P = .003) with endocrine remission. CONCLUSION According to our results, remission rate is significantly higher in microprolactinomas enclosed by the pituitary gland. However, the decision for surgery should take into account surgeons experience and possibility of complications.

Abstract
CONTEXT The improved remission and complication rates of current transsphenoidal surgery warrant reappraisal of the position of surgery as a viable alternative to dopamine agonists in the treatment algorithm of prolactinomas. OBJECTIVE To compare clinical outcomes after dopamine agonist withdrawal and transsphenoidal surgery in prolactinoma patients. METHODS Eight databases were searched up to July 13, 2018. Primary outcome was disease remission after drug withdrawal or surgery. Secondary outcomes were biochemical control and side effects during dopamine agonist treatment and postoperative complications. Fixed- or random-effects meta-analysis was performed to estimate pooled proportions. Robustness of results was assessed by sensitivity analyses. RESULTS A total of 1469 articles were screened: 55 (10 low risk of bias) on medical treatment (n = 3564 patients) and 25 (12 low risk of bias) on transsphenoidal surgery (n = 1836 patients). Long-term disease remission after dopamine agonist withdrawal was 34% (95% confidence interval [CI], 26-46) and 67% (95% CI, 60-74) after surgery. Subgroup analysis of microprolactinomas showed 36% (95% CI, 21-52) disease remission after dopamine agonist withdrawal, and 83% (95% CI, 76-90) after surgery. Biochemical control was achieved in 81% (95% CI, 75-87) of patients during dopamine agonists with side effects in 26% (95% CI, 13-41). Transsphenoidal surgery resulted in 0% mortality, 2% (95% CI, 0-5) permanent diabetes insipidus, and 3% (95% CI, 2-5) cerebrospinal fluid leakage. Multiple sensitivity analyses yielded similar results. CONCLUSIONS In the majority of prolactinoma patients, disease remission can be achieved through surgery, with low risks of long-term surgical complications, and disease remission is less often achieved with dopamine agonists.

Abstract
PURPOSE Renewed interest in transsphenoidal surgery (TSS) as a therapeutic option for prolactinomas has emerged. METHODS Based on contemporary literature and own experience, the changing role of surgery for treatment of prolactinomas is discussed. RESULTS Today, TSS is performed by minimally invasive microscopic or endoscopic techniques. Normoprolactinemia is obtained in 71-100% of patients with microprolactinomas by TSS. Almost equal results are found in circumscribed intrasellar macroprolactinomas. In experienced hands, pituitary function is preserved in TSS. The risk of cardiac valve disease is still a concern with ergot-derived dopamine-agonists (DAs) in patients requiring long-term, high-dose dopamine-agonist (DA) treatment. Cost-utility analysis favors TSS over DA treatment. The possible negative impact of DA treatment on future surgical results is still a controversial and unsettled issue. In patients who wish to become pregnant, the advantages of microprolactinoma removal to avoid DAs and macroprolactinoma debulking to avoid symptomatic enlargement during pregnancy should be discussed with the patients. Young patients' age is an argument for surgery to circumvent the unpredictable sequelae of long-term DA treatment. Surgery should be discussed in male gender because of a higher likelihood of DA resistance and aggressive behavior of prolactinoma. CONCLUSION Given excellent results of TSS and concerns about medical treatment, the scale of indications for TSS as an alternative to DAs has increased. The patient's wishes concerning a chance at a cure with TSS instead of a long-term treatment with DAs has become an important and accepted indication. With DA medication and TSS, two effective treatment modalities for prolactinomas are available that can be used in a complementary fashion.

Abstract
Thyroid disease mainly has a thyroid origin but can occasionally have a pituitary origin. Clinicians face several challenges when these conditions occur together. We aimed to determine the prevalence of thyroid disorders in patients undergoing trans-sphenoidal adenomectomy (TSA) for pituitary disease. We reviewed the medical records of patients undergoing TSA for pituitary disease between 2008 and 2017 at Severance Hospital. Thyroid disorders were categorized using blood test results and medical histories at the time of preoperative evaluation. Among 2202 patients, 44 (2%), 218 (9.9%), and 74 (3.4%) had hyperthyroidism, hypothyroidism, and post-thyroidectomy status before TSA, respectively. Among the 44 patients with hyperthyroidism, 30 (68.2%) had central hyperthyroidism. Among the 218 patients with hypothyroidism, 165 (75.7%) had central hypothyroidism. Central hypothyroidism was more common in patients with adrenocorticotropic hormone-secreting pituitary adenomas (aOR (adjusted odds ratio) 1.85), Rathke’s cleft cysts (aOR 2.34), and craniopharyngiomas (aOR 2.58) (all p < 0.05) than in those with nonfunctioning pituitary adenomas. Contrastingly, thyroid cancer had an increased prevalence in patients with growth hormone- (aOR 3.17), prolactin- (aOR 3.66), and thyroid-stimulating hormone-secreting (aOR 6.28) pituitary adenomas (all p < 0.05). Pituitary disease sometimes accompanies thyroid disorders; their characteristics vary according to the type of pituitary disease.

Abstract
While in the past surgery for prolactinomas was a competitive option to medical treatment with dopamine agonists, to date the indications for operations are restricted to only a few specific situations. However, if a patient is intolerant to medical treatment or if the drugs are not sufficiently effective in terms of lowering prolactin levels or tumor shrinkage, surgery should always be considered. In microprolactinomas, operations can achieve excellent prolactin normalization rates. In tumors difficult to treat, the combination of surgical tumor resection and long-term medical treatment supports better control of the disease. The individual indications, results, techniques, and complications of operations for prolactinomas are briefly reviewed in this paper.

Abstract
CONTEXT Prolactinoma is the most common subtype of functional pituitary adenoma. Effective therapy is required for women of child-bearing age to achieve remission at serum prolactin level and regain reproductive function. PURPOSE To evaluate long-term outcomes, including menstrual recovery, after transsphenoidal surgery on female prolactinoma patients by experienced neurosurgeons. DESIGN Observational study. PATIENTS Consecutive female prolactinoma patients aged from 16 to 45 years were included. Histological analysis after surgery revealed adenoma with positive staining for prolactin. Plurihormonal cell adenomas were excluded. MAIN MEASUREMENTS Clinical manifestations, surgical indications, serum prolactin level before and after surgery, surgical complications, pituitary fuctions, drug maintenance, the status of menstruation, and pregnancy. RESULTS Sixty-three consecutive female patients with a mean age of 29.5 ± 1.1 years were included. Based on magnetic resonance imaging findings before surgery, 31 (49.2%) patients had microadenoma, and the remaining 32 (50.8%) had macroadenoma. The median follow-up after transsphenoidal surgery was 53 (33-74) months, and long-term surgical remission was achieved in 50 (79.37%) patients with 28 (90.32%) microadenomas and 22 (68.75%) macroadenomas. No meningitis or persistent cerebrospinal fluid leaks occurred. Only one case suffered from persistent diabetes insipidus at follow-up. No severe pituitary dysfunction was observed in microprolactinoma patients. Of patients with menstrual disorders, 85% regained regular menstrual cycles after surgery. Nineteen patients in this cohort desired pregnancy and 15 of them successfully gave birth after surgery. All 17 microadenoma patients with modern surgical indications achieved normal prolactin levels and regular menstrual cycles with only one patient on drug therapy at follow-up. CONCLUSION Long-term follow-up showed a high remission rate in female prolactinoma patients, especially in microadenoma patients, after surgery. Transsphenoidal surgery performed by experienced neurosurgeons may offer a valuable approach to treat female microprolactinoma patients of child-bearing age with modern indications for surgery.

Abstract
PURPOSE Lactotroph adenomas (LA) are the most frequently encountered pituitary tumors. Although more frequently observed in women, LAs in men were recently included in a more aggressive category regardless of histological grading, by the WHO. We aimed to perform a rigorous retrospective review of a single center's pre-operative evaluation, patient characteristics and outcomes of male LAs patients requiring pituitary surgery. METHODS A retrospective review, over 11 years, of patients who underwent resection of a pituitary adenoma at a single center was conducted. Predictors of persistent disease in male LAs patients along with a comparison to predictors of silent corticotroph adenomas (SCAs) patients who also underwent surgery at the center was also conducted. RESULTS Thirty-one male patients with LAs were identified. When compared to SCAs patients, LAs male patients were younger (41 vs. 50 years of age, p = 0.01). Men with LAs had more invasive tumors (75% vs. 44.7% p = 0.02). More LAs in men had residual tumor after surgery than patients with SCA (92.6% vs. 42.1%, p < 0.001). Male patients with LAs and patients with SCA had similar rates of requiring additional surgery (28.9% vs. 24.1%, p = NS) and radiation therapy (18.4% vs. 19.4%, p = NS). CONCLUSIONS High rates of DA resistance, invasive tumors and postoperative residual disease in male patients with LA who required surgery are shown. Surgery improved optic chiasm compression, PRL level and central hypogonadism but, not surprisingly, failed to normalize other pituitary hormones and/or eliminate need for DA therapy.

Abstract
PURPOSE Surgical experience is considered paramount for excellent outcome of transsphenoidal surgery (TSS). However, objective data demonstrating the surgical success in relation to the experience of pituitary surgery units or individual experience of pituitary surgeons is sparse. METHODS Based on literature data, we have investigated the influence of experience with TSS for pituitary adenomas on endocrinological remission rates and on operative complications. The surgical experience was assessed by calculating the number of transsphenoidal operations per year. RESULTS For TSS of microprolactinomas, mean remission rates were 77% in centers with < 2 operations per year for microprolactinomas, 82% with 2-4 operations, 84% with 4-6 operations, and 91% with > 6 operations. A yearly experience with more than 10 initial operations for Cushing's disease (CD) warrants a remission rate exceeding 70%. Remission rates in CD exceeding 86% have only been reported for single surgeon series. Extraordinarily high complication rates were found in some series with < 25 yearly total operations for pituitary adenomas. Major vascular complications were less than 2% and revision rates for rhinorrhea usually < 2.5% in centers performing > 25 transsphenoidal operations per year. CONCLUSIONS We conclude that a center with experience of > 25 transsphenoidal operations for pituitary adenomas per year provides a high likelihood of safe TSS. Surgery for CD requires a particularly high level of practice to guarantee excellent remission rates. The endocrinologist has the unique opportunity to audit the surgical success by hormone measurement and to refer patients to neurosurgeons with proven excellence.

Abstract
Pituitary adenomas are one of the most common primary central nervous system tumors and have an estimated prevalence of 17%. Approximately half of pituitary adenomas secrete distinct pituitary hormones (most often prolactin, growth hormone, or adrenocorticotropic hormone). While these tumors are histologically benign, they have potent endocrine effects that lead to significant morbidity and shortened lifespan. Because of their pathophysiologic endocrine secretion and anatomic location near critical neural/vascular structures, hormone-secreting pituitary adenomas require defined management paradigms that can include relief of mass effect and biochemical remission. Management of hormone-secreting pituitary adenomas involves a multidisciplinary approach that can incorporate surgical, medical, and/or radiation therapies. Early and effective treatment of hormone-secreting pituitary adenomas can reduce morbidity and mortality. Consequently, understanding clinical features as well as therapeutic options in the context of the specific biological features of each type of hormone-secreting pituitary adenoma is critical for optimal management.

Abstract
Background: This meta-analysis aims to evaluate the long-term efficacy of medication treatment vs. surgery treatment in patients with prolactinomas. Methods: An electronic literature search was performed using MEDLINE, EMBASE and Web of Science databases for studies dated before July in 2018. Patients with prolactinomas received primary dopamine agonists (DAs) treatment or primary surgical interventions were included in this study. A systematic review and meta-analysis were performed in pertinent studies meeting eligible criteria. The clinical outcome was measured by the long-term remission rate of prolactin (PRL) in each cohort. The pooled data was analyzed according to a random effect model. Results: Thirteen publications with total 809 patients were included in the final meta-analysis. In the overall patients with prolactinomas, long-term remission rate was achieved in 88% patients treated with surgeries and in 52% patients treated with DAs (P = 0.001). The long-term remission rates in surgery cohort were also significantly higher than medication cohort in both microprolactinomas and macroprolactinomas (91 vs. 60%, P = 0.002; 77 vs. 43%, P = 0.003). Conclusions: Patients with prolactinomas, especially microprolactinomas, can consider transsphenoidal surgery as an alternative first-line treatment strategy. After receiving primary surgical intervention, administration of DAs should be considered based on the postoperative PRL level to achieve the best long-term remission rate.

Abstract
BACKGROUND Prolactinomas are the commonest functional tumors of the pituitary gland. There are still controversies regarding medical therapy in specific clinical situations. Patients may be managed by different specialists in the Middle East and North Africa (MENA) region and no data exist on patterns of clinical management. OBJECTIVES To ascertain the diagnostic and therapeutic approaches to prolactinomas among relevant professionals from the MENA region. METHODS An online survey of a large sample of physicians was conducted. The questionnaire covered various aspects of diagnosis and treatment of prolactinomas. 468 respondents were included; 36 % were endocrinologists; 49 % worked in public facilities and 81 % graduated more than 10 years. 40 and 30 % would have seen 1-5 and more than 5 suspected or confirmed prolactinomas over a 6 months period, respectively. RESULTS Regarding the diagnosis, 30 % of the respondents considered that prolactin levels <100 ng/ml exclude the presence of a prolactinoma. 21 % of respondents considered prolactin levels >250 ng/ml compatible with macroprolactinomas only, whereas others accepted this to be compatible also with microprolactinomas, macroprolactinaemia and drug-induced hyperprolactinemia (50, 42 and 36 % respectively). 71 % of respondents favored the screening for macroprolactin in asymptomatic individuals with hyperprolactinemia. Regarding the treatment, 84 % of respondents would treat microprolactinomas even in the absence of symptoms whereas 72 % of the respondents would treat microprolactinomas only if symptoms exist. 60 and 49 % of the respondents chose cabergoline as the drug of choice to treat macroprolactinomas and microprolactinomas respectively. Similar proportions had no preference of either cabergoline or bromocriptine as the best treatment for macroprolactinoma (27 %) and microprolactinomas (32 %). 46 and 75 % of respondents favored treatment withdrawal 2-3 years after prolactin normalization in patients with macroprolactinomas and microprolactinomas, respectively whereas 10 % of respondents withdraw treatment after menopause in either case. 94 % of respondents considered medical therapy as the primary treatment for microprolactinomas. In case of pregnancy, 49 % considered bromocriptine as the drug of choice for women who wish to become pregnant. 65 and 38 % of respondents advocated discontinuation of treatment with dopamine agonists in patients with microprolactinomas and macroprolactinomas, respectively. Finally, 48 % would allow breast-feeding without restriction, 28 % would restrict it to patients with microprolactinomas and 25 % would not recommend it for women with prolactinomas. CONCLUSIONS This is the first study of the clinical management of prolactinomas in the MENA region. Some of the practices are not in line with the latest Endocrine and Pituitary Societies guidelines. These warrant further discussions of contemporary guidelines in regional forums.

Abstract
Prolactinomas account for about 40% of all pituitary adenomas. The main treatment for prolactinomas is undoubtedly therapy with dopamine agonists (DAs). However, prolonged conservative treatment (for many years or even throughout life) that is necessary for permanent control of the disease makes some patients refuse pharmacological treatment for various reasons. In addition, not all prolactinomas respond to DAs therapy. Sometimes, the patient is not able to continue treatment because of the severity of side effects. Along with tumor resistance to therapy and patient intolerance of DAs, complications (liquorrhea, hemorrhage in the tumor) may occur during conservative treatment. In these cases, surgery is necessary. The paper analyzes the modern literature on various treatment options for prolactin-secreting pituitary adenomas and defines the indications for surgical treatment.

Abstract
While dopamine-agonists are the first-line approach in treating prolactinomas, surgery can be considered in selected cases besides non-responders or patients with dopamine-agonist intolerance. The aim of the present study was to compare the long-term outcome in women with prolactinomas treated primarily either surgically or medically who had not had prior dopamine-agonist treatment. Retrospective case-note study of all consecutive women with prolactinomas primarily managed with medical therapy or surgery in a tertiary referral centre. The clinical, biochemical, and radiological responses to first-line treatment at early and long-term follow-up were analysed. The primary therapeutic strategy was dopamine-agonists for 36 (34 %) and surgery for 71 (66 %) of the women. Baseline clinical and biochemical characteristics were not significantly different between the primary surgical and medical cohort. Median follow-up time was 90 months (range 13-408). Following primary treatment, prolactin level significantly decreased in both cohorts, on average to 13.5 µg/L (IQR 7-21; p < 0.001), and was within the normal range in 82 % of all patients. No women in the surgical cohort demonstrated permanent sequelae and morbidity was low. At final follow-up, control of hyperprolactinaemia required dopamine-agonist therapy in 64 % of women who had undergone primary medical therapy vs. 32 % of those who had primary surgical therapy (p = 0.003). Logistic regression revealed that the primary therapeutic strategy, but not adenoma size, was an independent risk factor for long-term dependence on dopamine-agonists. The present data indicate that in a dedicated tertiary referral centre, long-term control of hyperprolactinaemia in women with prolactinomas is high. In selected cases, a primary neurosurgical approach might at least be interdisciplinarily discussed with the primary goal of minimizing long-term dependence on dopamine-agonists.

Abstract
OBJECTIVE In men with prolactinomas, impaired bone density is the principle consequence of hyperprolactinemia-induced hypogonadism. Although dopamine agonists (DAs) are the first-line approach in prolactinomas, surgery can be considered in selected cases. In this study, we aimed to investigate the long-term control of hyperprolactinemia, hypogonadism, and bone health comparing primary medical and surgical therapy in men who had not had prior DA treatment. METHODS This is a retrospective case-note study of 44 consecutive men with prolactinomas and no prior DAs managed in a single tertiary referral center. Clinical, biochemical, and radiologic response to the first-line approach were analyzed in the 2 cohorts. RESULTS Mean age at diagnosis was 47 years (range, 22-78 years). The prevalence of hypogonadism was 86%, and 27% of patients had pathologic bone density at baseline. The primary therapeutic strategy was surgery for 34% and DAs for 66% of patients. Median long-term follow-up was 63 months (range, 17-238 months). Long-term control of hyperprolactinemia required DAs in 53% of patients with primary surgical therapy, versus 90% of patients with primary medical therapy (P = 0.02). Hypogonadism was controlled in 73% of patients. The prevalence of patients with pathologic bone density was 37% at last follow-up, with no differences between the 2 therapeutic cohorts (P = 0.48). CONCLUSIONS Despite control of hyperprolactinemia and hypogonadism in most patients independent of the primary treatment modality, the prevalence of impaired bone health status remains high, and osteodensitometry should be recommended.

Abstract
Microprolactinomas are the most common pituitary adenomas. In symptomatic patients, dopamine agonists are the first-line treatment of choice; when cabergoline is used, biochemical control rates between 85 and 93% have been reported. Long-term treatment is needed in most of the cases with compliance, patient convenience, and potential adverse effects representing areas requiring attention. Based on the literature published in the past 15 years, transsphenoidal surgery can lead to normal prolactin in the postoperative period in usually 71-100% of the cases with very low postoperative complication rates. Surgical expertise is the major determinant of the outcomes, and it may be a cost-effective option in young patients with life expectancy greater than 10 years (provided it is performed by experienced surgeons at high volume centers with confirmed optimal outcomes). Larger series of patients with adequate follow-up could further validate the place of transsphenoidal surgery (particularly through the endoscopic approach for which long-term results are currently limited) in the management algorithm of patients with microprolactinoma.

Abstract
BACKGROUND We report herein a retrospective analysis of the results of 142 consecutive prolactinoma cases operated upon using an endoscopic endonasal trans-sphenoidal approach over a period of 6 years. METHODS Medical records of 142 cases were analysed with respect to indications for surgery, duration of hospital stay, early remission rates, failures and recurrence rates during a median follow-up of 36 months. RESULTS On the basis of magnetic resonance imaging (MRI) data, 19 patients (13.4 %) had microadenoma, 113 (79.6 %) had macroadenoma, and the remaining 10 (7.0 %) had giant adenomas. Cavernous sinus invasion was identified in 25 patients by MRI and confirmed during surgery. Atypical adenoma was diagnosed in 16 patients. Sparsely granulated prolactin adenoma was identified in 99 patients (69.7 %). Our results demonstrate that male sex and higher preoperative prolactin levels are independent factors predicting persistent disease. The post-surgical complications are as follows: 2.8 % patients had meningitis, 2.1 % patients had postoperative cerebrospinal fluid leak and 2.1 % patients had panhypopituitarism. At the end of follow-up, 74.6 % patients went into remission. During follow-up period, five patients who had initial remission developed recurrence. CONCLUSIONS Our series together with literature data suggest that an endoscopic endonasal trans-sphenoidal approach in the treatment of proloctinomas has a favourable rate of remission. According to the findings of this study, endoscopic endonasal trans-sphenoidal surgery might be an appropriate therapy choice for patients with prolactinoma who could not have been managed with recommended therapeutic modalities.

Abstract
The purpose of this study was to examine the current indications for transsphenoidal surgery in the prolactinoma patient population, and to determine the outcomes of patients who undergo such operations. Transsphenoidal surgery may be indicated in prolactinoma patients who are resistant and/or intolerant to dopamine agonist (DA) therapy. We performed a retrospective review of the medical records of prolactinoma patients over a 6 year period (April 2008 to April 2014) at a large volume academic center. The median follow-up time was 12.0 months (range: 3-69). All patients who were included in the study (n=66) were treated with DA therapy and subsequently underwent an endonasal transsphenoidal operation. Of the 66 patients, 44 were women (mean age 34.2 years) and 22 were men (mean 41.7 years). There were 29 (43.9%) intolerant patients and 29 (43.9%) resistant patients. Postoperatively, 18 intolerant patients (66.7%) had normalized prolactin levels without the need for DA therapy, and five (17.2%) required DA to normalize their prolactin levels (p=0.02). Six patients (20.6%) had persistently elevated prolactin levels but were no longer receiving DA treatment (p<0.001). Postoperatively, 10 resistant patients (35.7%) had normal prolactin levels without DA therapy, and seven patients (25%) were treated with DA therapy to normalize their prolactin levels (p=0.22). Eight patients (28.6%) had supraphysiologic prolactin levels but were no longer taking a DA (p<0.001). Three patients (10.7%) were hyperprolactinemic, despite postoperative treatment with DA (p<0.001). After an appropriate treatment interval with multiple DA, radiographic follow-up, and careful clinical evaluation, prolactinoma patients can be offered surgery as an effective therapeutic option.

Abstract
The authors present an update on the various treatment modalities and discuss management strategies for prolactinomas. Prolactinomas are the most common type of functional pituitary tumor. Effective hyperprolactinemia treatment is of great importance, due to its potential deleterious effects including infertility, gonadal dysfunction and osteoporosis. Dopamine agonist therapy is the first line of treatment for prolactinomas because of its effectiveness in normalizing serum prolactin levels and shrinking tumor size. Though withdrawal of dopamine agonist treatment is safe and may be implemented following certain recommendations, recurrence of disease after cessation of the drug occurs in a substantial proportion of patients. Concerns regarding the safety of dopamine agonists have been raised, but its safety profile remains high, allowing its use during pregnancy. Surgery is typically indicated for patients who are resistant to medical therapy or intolerant of its adverse side effects, or are experiencing progressive tumor growth. Surgical resection can also be considered as a primary treatment for those with smaller focal tumors where a biochemical cure can be expected as an alternative to lifelong dopamine agonist treatment. Stereotactic radiosurgery also serves as an option for those refractory to medical and surgical therapy.

Abstract
Purpose. In low-income countries, prolactinomas are difficult to manage with dopamine agonists (DA). We compared the effectiveness of DA in microprolactinomas as a first line treatment and as adjuvant therapy for residual macroprolactinomas treated surgically. Methods. Our retrospective study analyzed 78 patients, 38 with microprolactinomas and 40 with macroprolactinomas. Microprolactinomas were treated with DA. Macroprolactinomas were treated with microsurgical or endoscopic adenomectomies and adjuvant DA. Surgical remission was defined as normoprolactinemia three months postoperatively, and long-term remission as normoprolactinemia at the last control. Results. Surgical remission was achieved in 9 patients (23%). Postsurgical tumor mass was reduced by 50% (34-68). Residual macroprolactinoma size was greater than microprolactinoma size prior to treatment (10 mm versus 4 mm, P < 0.001). Both groups received similar doses of DA. Long-term remission occurred in 68% of microprolactinomas and 43% of macroprolactinomas (P = 0.102). Prolactin (PRL) levels at the last control were similar in both groups (23.1 versus 32.9 mcg/L, P = 0.347). Conclusion. Comparable remission rates and PRL levels were reached in microprolactinomas and macroprolactinomas using similar doses of DA. Although complete tumor resection is the goal of surgery, our study suggests that even partial surgical removal has a role in treatment of prolactinomas since it may enhance the response to DA.

Abstract
Medical therapy with dopaminergic agonists (DAs) has been used for several decades for the treatment of both micro- and macroprolactinomas, without much differentiation between the two conditions. While most cases respond well to DAs in terms of prolactin normalization and control of tumor growth, DAs are often needed for many years, or even for lifetime. Concerns have been raised recently about the possible side effects of long-term use of these medications on the anatomy and function of the heart valves. While macroprolactinomas are rarely surgically curable, pituitary surgery in expert hands is a safe and effective method to permanently cure microprolactinomas, with long-term cure rates around 70 %. In this article, I will review the data on safety of DAs an on the effectiveness and safety of surgery, and I will make an argument that surgery should be offered as a possible therapy to microprolactinoma patients, provided that an experienced pituitary neurosurgeon is available.
