INTRODUCTION
Pituitary adenomas (PA) are common intracranial tumors. In the context of the aging of the population, the question is whether postsurgical outcomes are comparable to the younger ones. The primary objective of the present study was to review published resection and recurrence rates after transsphenoidal resection. The secondary aim was to evaluate visual improvement and complication rates.
METHODS
The authors searched PubMed and Medline databases, of published English series, with no time frame limit, evaluating outcomes of transsphenoidal resection in populations aged more or less than 65, 70, and 80 years. We performed a systematic review and meta-analysis.
RESULTS
Median overall resection rates for younger population was 70.7% (range 54-76.8) and for elderly one was 65.7% (range 16.6-78.2) (two-sample t test, p = 0.35). The only statistically significant difference for gross total resection rates (GTR) favored patients aged less than 80 (p = 0.01). There was no statistically significant difference among recurrence rates. There was a statistically significant difference for visual improvement favoring patients aged more than 80 (p = 0.03). For the age groups of less versus more than 70, there was a statistically significant difference for overall complication rate favoring younger groups (p < 0.05).
CONCLUSION
Present data shows GTR rates favoring younger patients. Recurrence rates remain similar over the mean follow-up period. Moreover, visual improvement favors patients aged more than 80. Overall complication rates favor patients younger than 70, which might be also related to additional comorbidities, frequently present in seniors. Transsphenoidal surgery is safe and effective even for older patients.

Review
Pituitary gland metastasis from primary tumours is uncommon on its own. Rarely, some of these primary tumours may be of unknown origin. This metastasis to the pituitary gland could manifest as diabetes insipidus, cranial nerve palsies, headaches, fatigue and other symptoms. In rare cases, it could present as loss of libido. We describe here this rare presentation, loss of libido, examine the diagnosis and management undertaken, and provide a systematic review of the literature for similar cases.

Meta-Analysis
BACKGROUND
Epilepsy is the most common symptom in patients with supratentorial low-grade gliomas (LGGs), which adversely affects the patient's quality of life. Poor seizure control with anti-epileptic therapy is an indication for surgery in these patients. Recent studies have sought to identify predictors of postoperative seizure control after surgical resection of LGG; gross total resection was shown to be a significant predictor in this respect. However, the prognostic value of other factors is not clear.
METHODS
We performed a systematic review and meta-analysis of 23 studies with a combined study population of 2641 patients with LGG, in order to identify potential factors associated with favorable postoperative seizure control. Data were extracted on age and sex of patient, tumor location, tumor histology, type of seizure, seizure duration, extent of resection, and imaging characteristics.
RESULTS
Patients ≥45 years of age achieved better postoperative seizure control (risk ratio [RR], 0.89; 95% CI, 0.81-0.99). Focal seizures were associated with poor seizure control (RR, 1.32; 95% CI, 1.18-1.49) compared with generalized seizures (RR, 0.77; 95% CI, 0.68-0.87). Prolonged history of seizures (≥1 y) had a negative impact on postoperative seizure control (RR, 1.22; 95% CI, 1.10-1.34). Gross total resection was superior to subtotal resection with respect to postoperative seizure control (RR, 0.68; 95% CI, 0.63-0.73).
CONCLUSIONS
This systematic review and meta-analysis identified predictors of postoperative seizure control in patients undergoing surgical resection of LGGs. Our results provide a reference for clinical treatment of LGG-related epilepsy.

Meta-Analysis
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.

PURPOSE
Heterogeneous reporting in baseline variables in patients undergoing transsphenoidal resection of pituitary adenoma precludes meaningful meta-analysis. We therefore examined trends in reported baseline variables, and degree of heterogeneity of reported variables in 30 years of literature.
METHODS
A systematic review of PubMed and Embase was conducted on studies that reported outcomes for transsphenoidal surgery for pituitary adenoma 1990-2021. The protocol was registered a priori and adhered to the PRISMA statement. Full-text studies in English with > 10 patients (prospective), > 500 patients (retrospective), or randomised trials were included.
RESULTS
178 studies were included, comprising 427,659 patients: 52 retrospective (29%); 118 prospective (66%); 9 randomised controlled trials (5%). The majority of studies were published in the last 10 years (71%) and originated from North America (38%). Most studies described patient demographics, such as age (165 studies, 93%) and sex (164 studies, 92%). Ethnicity (24%) and co-morbidities (25%) were less frequently reported. Clinical baseline variables included endocrine (60%), ophthalmic (34%), nasal (7%), and cognitive (5%). Preoperative radiological variables were described in 132 studies (74%). MRI alone was the most utilised imaging modality (67%). Further specific radiological baseline variables included: tumour diameter (52 studies, 39%); tumour volume (28 studies, 21%); cavernous sinus invasion (53 studies, 40%); Wilson Hardy grade (25 studies, 19%); Knosp grade (36 studies, 27%).
CONCLUSIONS
There is heterogeneity in the reporting of baseline variables in patients undergoing transsphenoidal surgery for pituitary adenoma. This review supports the need to develop a common data element to facilitate meaningful comparative research, trial design, and reduce research inefficiency.

Comparative Study Meta-Analysis
BACKGROUND
Over the past several decades, the endoscopic endonasal transsphenoidal approach (EETA) has gradually become a preferred option of pituitary adenomas surgery because of its minimal invasiveness and high efficiency. However, some EETA operations were performed through one nostril (mononostril), while other EETA operations were performed through both nostrils (binostril). Therefore, we conducted this study to compare the pros and cons of these two methods in an attempted to confirm which method is more effective.
METHODS
We executed a systematic literature search of PubMed, the Cochrane Library, and the Web of Science and Medline (1992-2015). The language is limited to English and all studies should meet the inclusion criteria. Comparisons were made for postoperative outcomes, complications, and other relevant parameters between the mononostril and the binostril group. Statistical analyses of categorical variables were undertaken by the use of Stata 12.0 and SPASS 19.0.
RESULTS
Thirty studies, involving 4805 patients, were included. The two groups had similar results in GTR rate (included GTR rate of macroadenomas), hormonal remission rate, improvement in visual function, postoperative CSF leak, permanent diabetes insipidus, meningitis, and sinusitis. The binostril group had less temporary diabetes insipidus (2.9% vs. 5.3%, p = 0.022), less anterior pituitary insufficiency (2.3% vs. 6.4%, p = 0.000) and few hospitalization days (3.2 days vs. 4.4 days, p<0.05) than the mononostril group. However, the mononostril group had less rate of epistaxis (0.4% vs. 1.5%, p = 0.008) than the binostril group. For invasive macroadenomas, the binostril group seem to demonstrate a tendency towards better outcomes though there was no subgroup analysis between the two groups.
CONCLUSION
The binostril approach had less temporary diabetes insipidus, anterior pituitary insufficiency, and a shorter length of hospital stay, although they demonstrated a higher rate of epistaxis than the mononstril group. Additionally, the binostril group seemed to suggest a tendency towards better outcomes for invasive macroadenomas.

Conservative treatment cures an elderly pituitary apoplexy patient with oculomotor paralysis and optic nerve compression: a case report and systematic review of the literature.
BACKGROUND
Whether conservative treatment or surgical management is the most appropriate treatment for pituitary apoplexy (PA) is controversial. In general, if severe symptoms of compression occur, such as oculomotor nerve palsy, neurosurgery is performed to relieve the compression of anatomical structures near the PA.
CASE DESCRIPTION
We describe the case of a 79-year-old man who was found to have an intrasellar pituitary incidentaloma. The tumor was discovered accidentally, during an investigation into the cause of his dizziness. Two months later, he suddenly developed headaches, left ophthalmoplegia, decreased vision, severe blepharoptosis and diplopia. He was diagnosed with PA and hypocortisolemia based on magnetic resonance imaging (MRI) and blood tests, respectively. His symptoms of oculomotor palsy and optic nerve compression were serious, but his ophthalmological deficits were nonprogressive and his hormone levels improved through conservative treatment (hydrocortisone supplementation). Due to this older patient's poor physical condition and serious coronary heart disease, after multidisciplinary consultation and according to his family's wishes, we continued the conservative treatment and watched closely for any changes in the patient's condition. After 6 months of conservative treatment, the patient's symptoms of oculomotor nerve paralysis, pupil and vision defects completely disappeared, and no new complications occurred. Repeated MRI tests showed that the PA lesion gradually improved. The patient's hypocortisolemia was completely relieved through oral supplementation with low-dose hydrocortisone.
CONCLUSION
In older PA patients who have surgical contraindications, even with symptoms of compression, such as oculomotor nerve palsy, according to the international guidelines, if conservative treatment is effective and the condition is not progressing, it is possible to monitor patients' condition closely and continue conservative treatment, which may yield good results.

Meta-Analysis
OBJECTIVE
Postoperative cerebrospinal fluid (CSF) leakage represents a challenge even for experienced pituitary surgeons. We aimed to quantitatively synthesize data from studies regarding the risk factors for postoperative CSF leakage after transsphenoidal surgery (TSS) for pituitary adenoma (PA).
METHODS
PubMed, Web of Science, The Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), Wanfang database, and VIP database were searched for case-control and cohort studies, focusing on the risk factors associated with postoperative CSF leakage after TSS for PA. Pooled odds ratios (ORs) and 95% confidence intervals were calculated to determine the risk factors.
RESULTS
A total of 34 case-control and cohort studies involving a total of 9,144 patients with PA were included in this systematic review. The overall rate of postoperative CSF leakage after TSS for PA was 5.6%. Tumor size, adenoma consistency, revision surgery, and intraoperative CSF leakage were independent risk factors for postoperative CSF leakage (ORs, 3.18-6.33). By contrast, the endoscopic approach showed a slight protective benefit compared with the microscopic approach in TSS (OR, 0.69).
CONCLUSIONS
This review provides a comprehensive overview of the quality of the evidence base, informing clinical staff of the importance of screening risk factors for postoperative CSF leakage after TSS for PA. More attention should be paid to PA patients at high risk for CSF leakage after TSS to reduce complications and improve prognosis.

Meta-Analysis
BACKGROUND
The role of adjuvant radiotherapy (RT) after gross total resection (GTR) of the World Health Organization (WHO) grade II ependymoma is controversial. Therefore, we aimed to compare the outcomes of adjuvant RT against observation after GTR of WHO grade II ependymoma. We also compared the outcomes of adjuvant RT against observation after subtotal resection (STR) of WHO grade II ependymoma and performed further subgroup analysis by age and tumor location.
METHODS
PubMed and Embase were systematically reviewed for studies published up till 25 November 2022. Studies that reported individual-participant data on patients who underwent surgery followed by adjuvant RT/observation for WHO grade II ependymoma were included. The exposure was whether adjuvant RT was administered, and the outcomes were recurrence and overall survival (OS). Subgroup analyses were performed by the extent of resection (GTR or STR), tumor location (supratentorial or infratentorial), and age at the first surgery (<18 or ≥18 years old).
RESULTS
Of the 4,647 studies screened, three studies reporting a total of 37 patients were included in the analysis. Of these 37 patients, 67.6% (25 patients) underwent GTR, and 51.4% (19 patients) underwent adjuvant RT. Adjuvant RT after GTR was not significantly associated with both recurrence (odds ratio =5.50; 95% confidence interval: 0.64-60.80; P=0.12) and OS (P=0.16). Adjuvant RT was also not significantly associated with both recurrence and OS when the cohort was analyzed as a whole and on subgroup analysis by age and tumor location. However, adjuvant RT was associated with significantly longer OS after STR (P=0.03) with the median OS being 6.33 years, as compared to 0.40 years for patients who underwent STR followed by observation.
CONCLUSIONS
Based on our meta-analysis of 37 patients, administration of adjuvant RT after GTR was not significantly associated with improvement in OS or recurrence in patients with WHO grade II ependymoma. However, due to the small number of patients included in the analysis, further prospective controlled studies are warranted.
