Meta-Analysis
Neurocognitive and psychological dysfunctions associated with pituitary adenomas (PAs) are clinically relevant, though probably under-reported. The aim of the current review is to provide an update on neuropsychological status, psychopathology, and perceived quality of life (QoL) in patients with PAs. A systematic research was performed in PubMed and Scopus in order to identify reports on neurocognitive, psychiatric, and psychological disorders in PAs. Prevalence of alterations, QoL evaluation, and used tests were also recorded. PRISMA guidelines were followed. Of 62,448 identified articles, 102 studies were included in the systematic review. The prevalence of neurocognitive dysfunctions was 15-83% in Cushing's Disease (CD), 2-33% in acromegaly, mostly affecting memory and attention. Memory was altered in 22% of nonfunctioning (NF) PAs. Worsened QoL was reported in 40% of CD patients. The prevalence of psychiatric disorders in CD reached 77% and in acromegaly 63%, mostly involving depression, followed by psychosis, and anxiety. The prevalence of psychopathology was up to 83% in CD, and 35% in acromegaly. Postoperative improvement in patients with CD was observed for: learning processes, overall memory, visuospatial skills, and language skills. Short-term memory and psychomotor speed improved in NFPAs. Postoperative improvement of QoL, somatic symptoms, obsessive-compulsive disorder, and coping strategies was seen in CD and acromegaly. Reports after radiotherapy are discordant. There is wide variability in used tests. PAs have been recently shown to be associated with altered neurocognitive and neuropsychological functions, as well as QoL. These data suggest the importance of a multidisciplinary evaluation for an optimal management.

Meta-Analysis
CONTEXT
Insight into the current landscape of patient-reported outcome (PRO) measures (PROM) and differences between PROs and conventional biochemical outcomes is pivotal for future implementation of PROs in research and clinical practice. Therefore, in studies among patients with acromegaly and growth hormone deficiency (GHD), we evaluated (1) used PROMs, (2) their validity, (3) quality of PRO reporting, (4) agreement between PROs and biochemical outcomes, and (5) determinants of discrepancies.
EVIDENCE ACQUISITION
We searched 8 electronic databases for prospective studies describing both PROs and biochemical outcomes in acromegaly and GHD patients. Quality of PRO reporting was assessed using the International Society for Quality of Life Research (ISOQOL) criteria. Logistic regression analysis was used to evaluate determinants.
EVIDENCE SYNTHESIS
Ninety studies were included (acromegaly: n = 53; GHD: n = 37). Besides nonvalidated symptom lists (used in 37% of studies), 36 formal PROMs were used [predominantly Acromegaly Quality of Life Questionnaire in acromegaly (43%) and Quality of Life-Assessment of Growth Hormone Deficiency in Adults in GHD (43%)]. Reporting of PROs was poor, with a median of 37% to 47% of ISOQOL items being reported per study. Eighteen (34%) acromegaly studies and 12 (32%) GHD studies reported discrepancies between PROs and biochemical outcomes, most often improvement in biochemical outcomes without change in PROs.
CONCLUSIONS
Prospective studies among patients with acromegaly and GHD use a multitude of PROMs, often poorly reported. Since a substantial proportion of studies report discrepancies between PROs and biochemical outcomes, PROMs are pivotal in the evaluation of disease activity. Therefore, harmonization of PROs in clinical practice and research by development of core outcome sets is an important unmet need.

Review
The review discusses the relationship between acromegaly and uterine fibroids. It highlights variations in research methodologies and inconsistent findings, emphasizing the complex nature of fibroid development and the role of the somatotropic axis. Additionally, it addresses demographic factors and examines the potential impact of therapies on the risk and prevalence of uterine fibroids in individuals with acromegaly. We conducted an analysis of previously published literature that examined the repercussions of acromegaly on gynecological health in female cohorts, with specific attention directed towards elucidating the prevalence of uterine fibroids. We suggest that larger, more focused studies are needed to understand the specific impact of different treatments on the occurrence of gynecological issues in acromegaly patients. Additionally, our study emphasizes the importance of factors such as disease duration and treatment effectiveness. We hypothesize that a relationship between acromegaly and uterine fibroids may occur. However, it remains an area of ongoing research, with the need for larger, multi-center studies to draw more definitive conclusions.

Meta-Analysis Review
PURPOSE
In patients with acromegaly, secondary treatment options in cases of hormonal non-remission or tumor progression include repeat transsphenoidal surgery (TSS), radiation-based treatment (RT), or medical therapy (MT). In this study, we aim to evaluate the clinical effectiveness of various second-line treatment options for acromegaly.
METHODS
Using the PRISMA guideline, a systematic review was performed by searching MEDLINE (PubMed), Web of Science, Scopus, and Cochrane electronic bibliographic databases from conception to the end of 2022. Outcomes of interest included hormonal remission rate, complications, and mortality associated with each treatment modality for refractory acromegaly.
RESULTS
A total of 79 studies including 3,208 refractory acromegaly patients (44.90% males) were analyzed, with a mean patient age of 43.89 years. There was a statistically significant difference between various therapeutic modalities in terms of remission rate, with MT offering the highest remission rate (62.55%), followed by RT (50.15%) and TSS (37.39%). Subgroup analysis of radiotherapeutic and medical modalities did not show a significant difference in remission rate between different kinds of sub-modalities in each treatment approach. Recurrence following secondary treatment was not different in patients treated with reoperation TSS compared to other modalities.
CONCLUSIONS
The management of persistent and recurrent acromegaly optimally requires a multimodal approach. In different scenarios of refractory acromegaly based on previous treatment, secondary treatments may vary in terms of remission rate and complications. Medical agents provide considerable effectiveness as a second-line therapy for recurrent or persistent disease. In selected cases, however, reoperation still provides an opportunity for cure or freedom from medications. The findings of this study may help clinicians to prioritize varying options involved in this multifaceted decision-making process.

BACKGROUND AND OBJECTIVE
Management of recurrent acromegaly is challenging for both neurosurgeons and endocrinologists. Several treatment options including repeat surgery, medical therapy, and radiation are offered for such patients. The efficacy of these modalities for the treatment of recurrence has not been studied previously in the literature. In this study, we aim to systematically review the existing cases of recurrence and come to a conclusion regarding the appropriate treatment in such cases.
METHOD
A systematic review was performed through PubMed, Scopus, Web of Science, and Cochrane database to identify studies reporting the treatment outcome of recurrent acromegaly patients. Using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, the included studies were reviewed for primary and secondary treatment, complications, and outcomes of the secondary treatment.
RESULTS
The systematic review retrieved 23 records with 95 cases of recurrent acromegaly. The mean time of recurrence was 4.16 years after the initial treatment. The most common primary treatment was surgery followed by radiotherapy. The remission rate was significantly higher in medical and radiotherapy compared to surgical treatment.
CONCLUSION
In cases of recurrent acromegaly, the patient may benefit more from radiotherapy and medical therapy compared to surgery. As the quality of evidence is low on this matter feature studies specifically designed for recurrent patients are needed.

BACKGROUND AND AIMS
Predictors of first-generation somatostatin receptor ligands (fgSRLs) response in acromegaly have been studied for over 30 years, but they are still not recommended in clinical guidelines. Is there not enough evidence to support their use? This systematic review aims to describe the current knowledge of the main predictors of fgSRLs response and discuss their current usefulness, as well as future research directions.
METHODS
A systematic search was performed in the Scopus and PubMed databases for functional, imaging, and molecular predictive factors.
RESULTS
A total of 282 articles were detected, of which 64 were included. Most of them are retrospective studies performed between 1990 and 2023 focused on the predictive response to fgSRLs in acromegaly. The usefulness of the predictive factors is confirmed, with good response identified by the most replicated factors, specifically low GH nadir in the acute octreotide test, T2 MRI hypointensity, high Somatostatin receptor 2 (SSTR2) and E-cadherin expression, and a densely granulated pattern. Even if these biomarkers are interrelated, the association is quite heterogeneous. With classical statistical methods, it is complex to define reliable and generalizable cut-off values worth recommending in clinical guidelines. Machine-learning models involving omics are a promising approach to achieve the highest accuracy values to date.
CONCLUSIONS
This survey confirms a sufficiently robust level of evidence to apply knowledge of predictive factors for greater efficiency in the treatment decision process. The irruption of artificial intelligence in this field is providing definitive answers to such long-standing questions that may change clinical guidelines and make personalized medicine a reality.

Review
OBJECTIVE
This study aims to evaluate the impact of surgical intervention on anxiety levels in patients with various types of pituitary adenoma (PA).
METHOD
A systematic review was conducted following PRISMA guidelines until October 2022, searching Embase, PubMed, Web of Sciences, and Scopus.
RESULTS
A total of 32 studies were included, encompassing 2,681 patients with the mean age of 53.33 ± 6.48 years (43.4% male). Among all subtypes, 664 diagnosed with Cushing's disease (25.8%), 612 with acromegaly (23.8%), 282 with prolactinoma (10.9%), and 969 with nonfunctional pituitary adenomas (37.6%). Pituitary insufficiency was the most common complication. Considering therapeutic modalities, 515 patients (29.8%) underwent endoscopic trans-sphenoidal surgery, while 222 (12.9%) underwent microscopic trans-sphenoidal surgery. The type of trans-sphenoidal surgery was not specified in 977 (56.6%) patients. A total of 17 studies including 1510 patients which mostly assessed anxiety using the Hospital Anxiety and Depression Scale (HADS) and Zung Self-Rating Anxiety Scale (SAS) were included in the meta-analysis. Preoperative evaluation using Hospital Anxiety and Depression Scale (HADS) questionnaire showed a pooled score of 8.27 (95%CI 4.54-12.01), while postoperative evaluation yielded a pooled score of 6.49 (95%CI 5.35-7.63), indicating no significant difference. Preoperative SAS assessment resulted in a pooled score of 50.43 (95%CI 37.40-63.45), with postoperative pooled score of 55.91 (95%CI 49.40-62.41), showing no significant difference.
CONCLUSIONS
Our analysis revealed no significant difference in anxiety scores pre- and postoperatively. While our findings suggest stability in anxiety levels following surgical intervention, it is imperative to recognize the limitations of the current evidence base. The observed lack of consensus may be influenced by factors such as the heterogeneous nature of the patient population, variations in the characteristics of pituitary adenomas, diverse therapeutic approaches, and potential confounding variables such as pre-existing mental health conditions and coping mechanisms. Further research is warranted to elucidate the nuanced relationship between surgical intervention for PA and anxiety outcomes, considering these complex interactions and employing rigorous methodologies to address potential sources of bias.

Meta-Analysis
OBJECTIVE
A systematic review was performed to provide objective evidence on the use of stereotactic radiosurgery (SRS) in the management of secretory pituitary adenomas and develop consensus recommendations.
METHODS
The authors performed a systematic review of the English-language literature up until June 2018 using the PRISMA guidelines. The PubMed (Medline), Embase, and Cochrane databases were searched. A total of 45 articles reporting single-institution outcomes of SRS for acromegaly, Cushing's disease, and prolactinomas were selected and included in the analysis.
RESULTS
For acromegaly, random effects meta-analysis estimates for crude tumor control rate, crude endocrine remission rate, and any new hypopituitarism rates were 97.0% (95% CI 96.0%-98.0%), 44.0% (95% CI 35.0%-53.0%), and 17.0% (95% CI 13.0%-23.0%), respectively. For Cushing's disease, random effects estimates for crude tumor control rate, crude endocrine remission rate, and any new hypopituitarism rate were 92.0% (95% CI 87.0%-95.0%), 48.0% (95% CI 35.0%-61.0%), and 21.0% (95% CI 13.0%-31.0%), respectively. For prolactinomas, random effects estimates for crude tumor control rate, crude endocrine remission rate, and any new hypopituitarism rate were 93.0% (95% CI 90.0%-95.0%), 28.0% (95% CI 19.0%-39.0%), and 12.0% (95% CI 6.0%-24.0%), respectively. Meta-regression analysis did not show a statistically significant association between mean margin dose with crude endocrine remission rate or mean margin dose with development of any new hypopituitarism rate for any of the secretory subtypes.
CONCLUSIONS
SRS offers effective tumor control of hormone-producing pituitary adenomas in the majority of patients but a lower rate of endocrine improvement or remission.

Meta-Analysis
BACKGROUND
Acromegaly is characterized by impaired bone quality and increased fracture risk. However, due to the pathophysiology of acromegalic osteopathy, bone mineral density (BMD) does not represent a reliable predictor for fragility fractures in this setting. Trabecular bone score (TBS) has been recently evaluated as an alternative index of skeletal fragility in acromegalic patients. However, no conclusive data are still available in this regard.
METHODS
PubMed/Medline, EMBASE, Cochrane Library, Ovid, and CINAHL databases were systematically searched until June 2022 for studies reporting data either about the comparison of TBS values between acromegalic patients and non-acromegalic controls or about the relationship - within acromegalic patients - between TBS values and fracture risk. Effect sizes were pooled through a random-effect model.
RESULTS
Eight studies were eligible for inclusion in the meta-analysis, encompassing 336 acromegalic patients and 490 non-acromegalic controls. Overall, TBS was significantly lower in acromegalic patients compared to controls (-0.089, 95% CI: [-0.111, -0.067], p < 0.01), irrespective of acromegaly disease activity and gonadal status. With respect to fracture risk, TBS was significantly lower in acromegalic patients with vertebral fractures than in those without (-0.099, 95% CI: [-0.166, -0.032], p < 0.01).
CONCLUSION
In this meta-analysis, we specifically assessed the role of TBS as an index of bone quality and fracture risk in patients with acromegaly. Our results support the notion that TBS could be of value in the assessment and management of skeletal fragility in acromegalic patients, especially in light of the poor information provided in this setting by BMD.

UNLABELLED
Acromegaly is a rare endocrine disorder caused by hypersecretion of growth hormone (GH) from a pituitary adenoma. Elevated GH levels stimulate excess production of insulin-like growth factor 1 (IGF-1) which leads to the insidious onset of clinical manifestations. The most common primary central nervous system (CNS) tumors, meningiomas originate from the arachnoid layer of the meninges and are typically benign and slow-growing. Meningiomas are over twice as common in women as in men, with age-adjusted incidence (per 100,000 individuals) of 10.66 and 4.75, respectively. Several reports describe co-occurrence of meningiomas and acromegaly. We aimed to determine whether patients with acromegaly are at elevated risk for meningioma. Investigation of the literature showed that co-occurrence of a pituitary adenoma and a meningioma is a rare phenomenon, and the majority of cases involve GH-secreting adenomas. To the best of our knowledge, a systematic review examining the association between meningiomas and elevated GH levels (due to GH-secreting adenomas in acromegaly or exposure to exogenous GH) has never been conducted. The nature of the observed coexistence between acromegaly and meningioma -whether it reflects causation or mere co-association -is unclear, as is the pathophysiologic etiology.
