Abstract
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.

Abstract
Strong lines of evidence in the neuroscience literature indicate that (a) healthy sleep facilitates cognitive processing, and (b) sleep disruption is associated with cognitive dysfunction. Despite the fact that patients with pituitary disease often display both disrupted sleep and cognitive dysfunction, few previous studies investigate whether these clinical characteristics in these patients might be related. Hence, we explored whether sleep disruption in patients with pituitary disease mediates their cognitive dysfunction. We recruited 18 patients with non-functioning pituitary adenomas (NFPA) and 19 sociodemographically matched healthy controls. They completed the Global Sleep Assessment Questionnaire (thus providing self-report data regarding sleep disruption) and were administered the Brief Test of Adult Cognition by Telephone, which assesses cognitive functioning in the domains of processing speed, working memory, episodic memory, inhibition, and reasoning. We found no significant differences in cognition between patients and controls. Furthermore, spectra of sleep disturbance did not differ significantly between patients and controls. Our data suggest that NFPA patients' cognition and sleep quality is relatively intact, and that sleep disruption does not mediate cognitive dysfunction. Larger studies should characterize sleep and cognition in patients with NFPA (and other pituitary diseases) to confirm whether disruption of the former mediates impairment in the latter.

Abstract
Cognitive abilities are impaired in patients with pituitary adenoma. However, studies on attention processing impairment in preoperative patients and attention processing recovery after transsphenoidal adenomectomy are lacking. The study aims to identify the electrophysiological change that relates to attention processing in pituitary patients before and after treatment. Twenty five preoperative pituitary patients and 25 follow-up postoperative patients were recruited. 27 healthy controls (HCs) were matched to the patients with age, gender, and education. Event-related potentials were used to investigate the attention processing in the preoperative patients, postoperative patients, and HCs. Across three groups, all emotional stimuli evoked P200 components. Compared with the HCs or postoperative patients, the amplitudes of P200 in the preoperative patients were higher. Moreover, The amplitudes of P200 decreased in the postoperative patients, which were similar to that in the HCs. The attention processing was improved after surgery, but no significant differences were detected between the postoperative patients and HCs. Abnormal hormone levels may be relevant to the factor that impair attention processing. Compared with that of the HCs and postoperative patients, the P200 component elicited by negative stimuli is higher in preoperative patients, which may illustrate compensatory activity after attention impairments. Furthermore, these data indicate that improvements in attention processing may be attributed to the amelioration of endocrine disorders. This study shows that the P200 component may be used to diagnose attention processing in preoperative pituitary patients and prove the improvement of attention processing in postoperative patients.

Abstract
Prolactinomas have been reported for the failure of cognitive functions. However, the electrophysiological mechanisms of attention processing in prolactinomas remain unclear. In a visual mission, we monitored the scalp electroencephalography (EEG) of the participants. Compared with the healthy controls (HCs), larger frontoparietal theta and alpha coherence were found in the patients, especially in the right-lateralized hemisphere, which indicated a deficit in attention processing. Moreover, the frontoparietal coherence was positively correlated with altered prolactin (PRL) levels, implying the significance of PRL for adaptive brain compensation in prolactinomas. Taken together, this research showed the variations in attention processing between the HCs and prolactinomas. The coherence between frontal and parietal regions may be one of the possible electrophysiological biomarkers for detecting deficient attention processing in prolactinomas.

Abstract
Neurocognitive complaints are common in patients with pituitary tumours, particularly in memory and concentration. Past studies have shown impairments in executive function and memory, but it is not clear whether these result from direct effects of the tumour (pressure or hormonal secretion), incidental damage from radiotherapy or surgical treatments, and/or mediating psychiatric factors. This study assessed cognitive function and psychiatric state of 86 pituitary tumour patients and 18 healthy controls, pre and post-treatment, to examine the effects of tumour aetiology and treatment type. No significant cognitive impairments were found, except on verbal recognition memory. Patients with Cushing's disease showed lower verbal recognition memory than the other groups pre-treatment, but improved at follow-up. This was (at least partially) accounted for by an improvement in depression scores. Patients who were treated with surgery showed poorer verbal recognition memory than controls across all (pre- and post-treatment) time-points. Overall findings of minimal cognitive impairment in patients with pituitary tumours may reflect improved diagnostic and treatment techniques in recent years. We suggest that the verbal memory impairments identified in the Cushing's group may result from increased cortisol (directly, or mediated by depression). In the surgical groups, verbal memory impairments appeared to pre-date treatment. This may relate to treatment selection factors, rather than harmful effects of surgery itself.

Abstract
OBJECTIVEPituitary adenomas and the treatment required for the underlying neuropathology have frequently been associated with cognitive dysfunction. However, the mechanisms for these impairments remain the subject of much debate. The authors evaluated cognitive outcomes in patients treated with or without Gamma Knife radiosurgery (GKRS) for an underlying pituitary adenoma.METHODSThis was a retrospective, institutional review board-approved, single-institution study. A total of 51 patients (23 male, 28 female) treated for pituitary adenoma were included in this neurocognitive study. Twenty-one patients underwent GKRS following transsphenoidal surgery, 22 patients were treated with transsphenoidal surgery alone, and eight patients were conservatively managed or were treated with medical management alone. Comparisons using psychometric tests of general intellectual abilities, memory, and executive functions were made between the treatment groups, between male and female patients, and between patients with Cushing's disease and those with nonfunctioning adenoma (NFA).RESULTSThe entire patient sample, the NFA group, and the GKRS group scored significantly below expected on measures of both immediate and delayed memory, particularly for visually presented information (p ≤ 0.05); however, there were no significant differences between the patients with Cushing's disease and those with NFA (t ≤ 0.56, p ≥ 0.52). In those who underwent GKRS, memory scores were not significantly different from those in the patients who did not undergo GKRS (t ≤ 1.32, p ≥ 0.19). Male patients across the sample were more likely to demonstrate impairments in both immediate memory (t = -3.41, p = 0.003) and delayed memory (t = -3.80, p = 0.001) than were female patients (t ≤ 1.09, p ≥ 0.29). There were no impairments on measures of general intellectual functioning or executive functions in any patient group. The potential contributions of tumor size and hormone levels are discussed.CONCLUSIONSOverall, pituitary adenoma patients demonstrated relative impairment in anterograde memory. However, GKRS did not lead to adverse effects for immediate or delayed memory in pituitary adenoma patients. Cognitive assessment of pituitary adenoma patients is important in their longitudinal care.

Abstract
OBJECTIVE Patients with nonfunctioning pituitary adenomas (NFPAs) can suffer from cognitive dysfunction. However, the literature on longitudinal cognitive follow-up of patients undergoing endoscopic endonasal transsphenoidal surgery (EETS) is limited. This study was performed to investigate perioperative cognitive status and course in patients with NFPAs. METHODS Patients underwent computerized neuropsychological assessment 1 day before (n = 45) and 3 months after (n = 36) EETS. Performance in 7 domains was measured with a computerized test battery (CNS Vital Signs) and standardized using data from a healthy control group. The authors conducted analyses of cognitive performance at both time points and changes pre- to post-ETSS on a group and an individual level. Linear multiple regression analyses were employed to investigate predictors of cognitive performance. RESULTS On average, patients scored significantly lower in 6 of 7 cognitive domains before and after surgery than controls. Impairment proportions were significantly higher among patients (56% before surgery, 63% after surgery) than among controls. Patients showed no change over time in group-level (mean) performance, but 28% of individual patients exhibited cognitive improvement and 28% exhibited cognitive decline after surgery. Hormonal deficiency showed a positive correlation with verbal memory before surgery. Postoperative performances in all cognitive domains were predicted by preoperative performances. CONCLUSIONS Cognitive impairment was present before and after EETS in over half of NFPA patients. Individual patients showed diverse postoperative cognitive courses. Monitoring of cognitive functioning in clinical trajectories and further identification of disease-related and psychological predictors of cognition are warranted.

Abstract
Treatment of Cushing's disease (CD) is one of the most challenging tasks in endocrinology. The first-line treatment, transsphenoidal pituitary surgery, is associated with a high failure rate and a high prevalence of recurrence. Re-operation is associated with an even higher rate of a failure and recurrence. There are three main second-line treatments for CD - pituitary radiation therapy (RT), bilateral adrenalectomy and chronic cortisol-lowering medical treatment. All these treatments have their limitations. While bilateral adrenalectomy provides permanent cure of the hypercortisolism in all patients, the unavoidable chronic adrenal insufficiency and the risk of development of Nelson syndrome are of concern. Chronic cortisol-lowering medical treatment is not efficient in all patients and side effects are often a limiting factor. RT is efficient for approximately two-thirds of all patients with CD. However, the high prevalence of pituitary insufficiency is of concern as well as potential optic nerve damage, development of cerebrovascular disease and secondary brain tumours. Thus, when it comes to decide appropriate treatment for patients with CD, who have either failed to achieve remission with pituitary surgery, or patients with recurrence, the pros and cons of all second-line treatment options must be considered.

Abstract
BACKGROUND Cognitive impairments have been reported in patients with pituitary adenomas (PAs). The aim of this research was to demonstrate the effects of hormones and age on cognitive decline in patients with PAs. METHODS A total of 64 patients with PA and 69 healthy control subjects (HCs) were recruited for this study. Both PAs and HCs were divided into a younger group (<50 years of age) and an older group (≥50 years of age). Neurocognitive domains were assessed using the Wechsler Adult Intelligence Scale-Chinese Revision (WAIS-RC) and Wechsler Memory Scale-Chinese Revision (WMS-RC) tests. Furthermore, we also investigated the relationship between cognitive domains and tumor volume, and the hormone levels and age of patients with PA. RESULTS Several of the cognitive impairments found on the WAIS-RC and WMS-RC tests were more frequently observed in untreated patients with PA. Importantly, no significant correlations were found between cognitive domains and tumor volume after controlling age, sex, and educational levels. Furthermore, several significant correlations were found between cognitive domains and hormone levels, such as free thyroxine and adrenocorticotropic hormone, after controlling age, sex, and educational levels. Finally, the age of the patients was found to correlate with a decrease in memory after controlling sex and educational levels. CONCLUSIONS Our findings demonstrate a significant decline in the cognitive performance of patients with PA prior to medical treatment, especially in older patients, which suggests that hormones and age have the ability to interact and aggravate cognitive decline in patients with PA.

Abstract
Radiation therapy (RT) is an effective treatment for patients with either nonfunctioning or secreting pituitary adenomas unsuccessfully treated by surgery and/or medical therapy, resulting in local control of 90-95% at 5-10 years and variable normalization of hormonal hypersecretion for patients with GH-, ACTH-, and prolactin-secreting adenomas in the range of 40-80% at 5 years; however, its use has been limited because of concerns regarding potential late toxicity of radiation and delayed efficacy in normalization of hormone hypersecretion. In the last decades, there have been advances in all aspects of radiation treatment, including more accurate immobilization, imaging, treatment planning and dose delivery. RT has evolved with the development of highly conformal stereotactic techniques and new planning and dose delivery techniques, including intensity-modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT). All these new techniques allow precise and sharply focused radiation delivery reducing the dose to surrounding critical neurovascular and brain structures, and potentially limiting the long-term consequences of radiation treatments. In this review, we present a critical analysis of the more recent available literature on the use of RT in patients with both nonfunctioning and secreting pituitary adenomas, focussing particularly on the risk/benefit ratio of modern radiation techniques.

Abstract
After treatment for a non-functioning pituitary adenoma (NFA) health-related quality of life (HR-QoL) improves considerably. However, the literature about the normalization of HR-QoL after treatment is inconclusive. Some researchers described a persistently decreased HR-QoL compared to reference data, while others did not. Considering this variety in observed HR-QoL outcomes, the aim of the present review was to provide a literature overview of health outcomes in patients with a NFA, using a conceptual HR-QoL model. A concrete conceptualization of the health outcomes of patients with a NFA can be helpful to understand the observed variety in HR-QoL outcomes and to improve clinical care and guidance of these patients. For this conceptualization, the Wilson and Cleary model was used. This model has a biopsychosocial character and has been validated in several patient populations. In the present review, health outcomes of patients with a NFA were described at each stage of the model e.g. biological and physiological variables, symptom status, functional status, general health perceptions and overall HR-QoL. The Wilson-Cleary model elucidates that elements at each stage of the model can contribute to the impairment in HR-QoL of patients with a NFA, which explains the reported variety in the literature. Furthermore, by applying the model, potential interventions targeting these elements can be identified. While optimal biomedical treatment has always been the focus, it is clearly not sufficient for good HR-QoL in patients with a NFA. Further improvement of HR-QoL should be supported by a pituitary specific care trajectory, including psychosocial care (e.g. self-management training), to beneficially affect characteristics of the patient and the (healthcare) environment, with the utmost goal to optimize HR-QoL in patients after treatment.

Abstract
AIMS Acromegaly is caused by a pituitary adenoma that releases excess growth hormone (GH) and a concomitant increase in insulin-like growth factor 1 (IGF-1). Acromegaly results not only in phenotypic changes, but also in neurologic complications as peripheral neuropathy and cognitive dysfunction. This study aimed to compare depressive mood and cognitive function in patients with acromegaly and in healthy controls as well as to determine the factors underlying cognitive dysfunction in the acromegalic patients. MATERIALS AND METHODS This study included 42 patients with acromegaly that were receiving somatostatin analogue therapy and 44 healthy controls. Memory, attention, visuospatial function, inhibitory function, abstract thinking, verbal fluency, and depressive mood were measured in the patients and controls. RESULTS Patients with acromegaly had lower learning (p = 0.01), planning (p = 0.03), complex attention and inhibitory function (p = 0.04) scores than the controls. There was no significant difference in depressive mood between the patients and controls (p > 0.05). Gamma knife radiosurgery did not negatively affect cognitive function (p > 0.05). CONCLUSION The present findings show that acromegaly negatively affects learning, attention, and planning.

Abstract
Stereotactic radiosurgery (SRS) delivered as either single-fraction or multi-fraction SRS (2–5 fractions) is frequently employed in patients with residual or recurrent pituitary adenoma. The most common delivery systems used for SRS include the cobalt-60 system Gamma Knife, the CyberKnife (CK) robotic radiosurgery system, or a modified conventional radiotherapy machine (linear accelerator, LINAC). Tumor control and normalization of hormone hypersecretion have been reported in 75–100 % and 25–80 % of patients, respectively. Hypopituitarism is the most commonly reported late complication of radiation treatment, whereas other toxicities occur less frequently. We have provided an overview of the recent available literature on SRS in patients with a pituitary adenoma. Critical aspects of pituitary irradiation, including target delineation and doses to organs at risk, optimal radiation dose, as well as the long-term efficacy and toxicity of SRS for either nonfunctioning or secreting pituitary adenomas are discussed. Single-fraction SRS represents an effective treatment for patients with a pituitary adenoma; however, caution should be used for lesions > 2.5–3 cm in size and/or involving the anterior optic pathway. Future studies will be necessary to optimize target doses and critical organ dose constrains in order to reduce the long-term toxicity of treatments while maintaining high efficacy.

Abstract
This aim of this study was to compare the doses received by critical cranial organs when three different radiation techniques were used to treat pituitary tumours. Cranial computed tomography scans of a RANDO phantom and 30 patients were used for pituitary macroadenoma radiotherapy treatment planning. For each slice, target volumes and other critical organs were contoured and three techniques were applied: (A) two parallel-opposed lateral fields, (B) two oblique fields (45°) in coronal plane and (C) two parallel-opposed lateral and anterior fields while the head was tilted 45° in the sagittal plane. The doses received by the target volume and the critical organs for each technique were calculated for all patients. Irradiation was repeated three times for each technique. Finally, the doses that reached the organs of interest resulting from these techniques were compared. The dose delivered to the temporal lobes was 105, 9 and 72 % of the prescribed dose using techniques A, B and C, respectively. The dose received by the cochlea was the lowest in technique C (27 % of prescribed dose) compared with techniques A (79 %) and B (48 %). All techniques delivered 100 % of the prescribed dose to the chiasma. Technique A increased the dose to temporal lobes and the cochlea to such an extent that they exceeded the tolerance dose. Technique B spared the temporal lobes better than technique C; however, technique C was preferred since the dose received by the cochlea in this case was the lowest of all techniques. None of the techniques spared the chiasma.

Abstract
Radiotherapy has, historically, played a central role in the management of acromegaly, and the last 30 years have seen substantial improvements in the technology used in the delivery of radiation therapy. More recently, the introduction of highly targeted radiotherapy, or 'radiosurgery', has further increased the therapeutic options available in the management of secretory pituitary tumors. Despite these developments, improvements in primary surgical outcomes, an increase in the range and effectiveness of medical therapy options, and long-term safety concerns have combined to dictate that, although still deployed in selected cases, the use of radiotherapy in the management of acromegaly has declined steadily over the past 2 decades. In this article, we review some of the main studies that have documented the efficacy of pituitary radiotherapy on growth hormone hypersecretion and summarize the data around its potential deleterious effects, including hypopituitarism, cranial nerve damage, and the development of radiation-related intracerebral tumors. We also give practical recommendations to guide its future use in patients with acromegaly, generally, as a third-line intervention after neurosurgical intervention in combination with various medical therapy options.

Abstract
PURPOSE To assess the long-term impact of postoperative two-field-conventional radiotherapy (RT) on neurocognitive functions of adult patients with operated pituitary adenomas (PA). METHODS We selected 124 adult patients with operated PA-56 of whom had also received RT-recorded their main clinical data and performed a neuropsychological assessment in all of them that included 15 standardized tests, and a cerebral SPECT in eight patients. Comparative analyses were carried out on major clinical and neurocognitive domains between irradiated and not irradiated patients, and on cerebral SPECT source. RESULTS Compared with non-irradiated patients, irradiated patients performed significantly worse on Barcelona's story recall test (P < 0.001) and arithmetic problems (P < 0.03) and on five categories of the Wisconsin card sorting test, especially on perseverative answers and errors (P < 0.001) without differences in other examined functional domains. RT was the only factor associated with worse results in these tests regardless other clinical and treatment-related variables. Kaplan-Meier analysis suggested that the probability of achieving poorer results with time was related to RT total dose and field-size, type of PA and age at the time of RT. Four of the five SPECTS performed in irradiated patients revealed a similar altered perfusion in the left temporal lobe cortical region. CONCLUSIONS In adult patients with operated PA, RT was independently associated with an impairment on verbal memory and executive function, when compared to non-irradiated patients. Our data suggest that diagnosis of acromegaly or Cushing's disease, and age at the time of RT were able to modulate this long-term radio-induced neurocognitive sequelae.

Abstract
PURPOSE Adult patients operated for craniopharyngioma develop more frequently GH deficiency (GHD) than patients operated for non-functioning pituitary adenoma (NFPA). The aim of the study was to compare both short- (1 year) and long-term (5 years) effects of rhGH in 38 GHD adult patients (19 operated for Craniopharyngioma (CP) and 19 for NFPA). METHODS IGF-I levels, body composition (BF%), BMI, lipid profile and glucose homeostasis were evaluated in all patients. Pituitary MRI was performed at baseline and during follow-up, as needed. RESULTS At baseline no difference between the two groups was observed, apart from a higher prevalence of diabetes insipidus in CP patients (79 vs 21%). After 12 months, IGF-I SDS normalized and BF% significantly decreased only in the NFPA group. During long-term treatment, decrease in BF% and improvement in lipid profile shown by reduction in total- and LDL-cholesterol were present in NFPA group only, while increase in insulin levels and HbA1c and decrease of QUICKI were observed in CP patients only. Accordingly, after long-term therapy, the prevalence of metabolic syndrome (MS) was significantly higher in CP than in NFPA group (37% in CP and in 5% in NFPA group; p < 0.05). CONCLUSION The present data suggest that CP patients are less sensitive to the positive rhGH effects on lipid profile and BF% and more prone to insulin sensitivity worsening than NFPA patients, resulting in increased prevalence of MS in CP only.

Abstract
OBJECTIVE We describe the use of fractionated stereotactic radiotherapy (FSRT) for the treatment of large, invasive, nonfunctioning pituitary adenomas (NFPAs). FSRT is frequently employed for the treatment of residual or recurrent pituitary adenomas. PATIENTS AND METHODS Sixty-eight patients with a large residual or recurrent NFPAs were treated between April 2004 and December 2012, including 39 males and 29 females (median age 51 years). Visual defects were present in 34 patients, consisting of visual field defects (n=31) and/or reduced visual acuity (n=12). Forty-five patients had evidence of partial or total hypopituitarism before FSRT. For most of the patients, the treatment was delivered through 5-10 noncoplanar conformal fixed fields using a 6-MV linear accelerator to a dose of 45 Gy in 25 fractions. RESULTS At a median follow-up of 75 months (range 12-120 months), the 5- and 10-year actuarial local control were 97 and 91%, respectively, and overall survival 97 and 93%, respectively. Forty-nine patients had a tumor reduction, 16 remained stable, and three progressed. The relative tumor volume reduction measured using three-dimensional (3D) magnetic resonance imaging (MRI) was 47%. The treatment was well tolerated with minimal acute toxicity. Eighteen patients developed partial or complete hypopituitarism. The actuarial incidence of new anterior pituitary deficits was 40% at 5 years and 72% at 10 years. No other radiation-induced complications occurred. CONCLUSIONS Our results suggest that FSRT is an effective treatment for large or giant pituitary adenomas with low toxicity.

Abstract
The purpose of this study was to investigate whether a new O‐ring design radiotherapy delivery system has advantages in radiotherapy planning for skull‐base tumors. Twenty‐five patients with skull‐base tumors were included in this study. Two plans were made using conventional (Plan A) or new (Plan B) techniques. Plan A consisted of four dynamic conformal arcs (DCAs): two were horizontal, and the other two were from cranial directions. Plan B was created by converting horizontal arcs to those from caudal directions making use of the O‐ring design radiotherapy system. The micromultileaf collimators were fitted to cover at least 99% of the planning target volume with prescribed doses, 90% of the dose at the isocenter. The two plans were compared in terms of target homogeneity, conformity, and irradiated volume of normal tissues, using a two‐sided paired t‐test. For evaluation regarding target coverage, the homogeneity indices defined by the International Commission on Radiation Units and Measurements 83 were 0.099±0.010 (mean ± standard deviation) and 0.092±0.010, the conformity indices defined by the Radiation Therapy Oncology Group were 1.720±0.249 and 1.675±0.239, and the Paddick's conformity indices were 0.585±0.078 and 0.602±0.080, in Plans A and B, respectively. For evaluation of irradiated normal tissue, the Paddick's gradient indices were 3.118±0.283 and 2.938±0.263 in Plans A and B, respectively. All of these differences were statistically significant (p‐values <0.05). The mean doses of optic nerves, eyes, brainstem, and hippocampi were also significantly lower in Plan B. The DCA technique from caudal directions using the new O‐ring design radiotherapy system can improve target homogeneity and conformity compared with conventional DCA techniques, and can also decrease the volume of surrounding normal tissues that receives moderate doses.

Abstract
Background Stereotactic radiosurgery (SRS) is a common treatment for recurrent or residual pituitary adenomas. The persistence of symptoms and treatment related complications may impair the patient’s quality of life (QOL). Purpose The purpose of this study was to examine symptom distress, QOL, and the relationship between them among patients with pituitary tumors who had undergone SRS. Methods This study used a cross-sectional design and purposive sampling. We enrolled patients diagnosed with pituitary tumors who had undergone SRS. Data were collected at the CyberKnife Center at a medical center in Northern Taiwan in 2012. A questionnaire survey was used for data collection. Our questionnaire consisted of 3 parts the Pituitary Tumor Symptom Distress Questionnaire, the World Health Organization Quality of Life Instrument Short-Form (WHOQOL-BREF), and a demographic questionnaire. Results Sixty patients were enrolled in the study. The most common symptoms reported by patients after SRS were memory loss, fatigue, blurred vision, headache, sleep problems, and altered libido. The highest and lowest scores for QOL were in the environmental and psychological domains, respectively. Age was positively correlated with general health and the psychological domains. Level of symptom distress was negatively correlated with overall QOL, general health, physical health, and the psychological and social relationships domains. The scores in the psychological and environmental domains were higher in males than in females. Patients with ≤6 symptoms had better overall QOL, general health, physical health, and psychological and social relationships than those with >6 symptoms. Conclusion Symptom distress can affect different aspects of patient QOL. Levels of symptom distress, number of symptoms, age, and gender were variables significantly correlated with patient QOL. These results may be utilized by healthcare personnel to design educational and targeted interventional programs for symptom management to improve patient QOL.

Abstract
CONTEXT Little is known of the importance of previous irradiation therapy for baseline characteristics and responsiveness to GH replacement in GH deficient (GHD) adults. OBJECTIVE/DESIGN/PATIENTS In this prospective, single-centre, open-label study, the effects of 10-year GH replacement were determined in 18 GHD adults that had previously received conventional external fractionated pituitary irradiation therapy (IRR group) and 18 non-irradiated GHD patients (non-IRR group). All patients had adult onset disease and complete deficiency of anterior pituitary hormones and both groups were comparable in terms of age, gender, body mass index (BMI), and waist:hip ratio. RESULTS At baseline, IRR patients had higher serum triglyceride (TG) and insulin levels and lower high density lipoprotein (HDL)-cholesterol (HDL-C) level than non-IRR patients (all p<0.05). The 10-year GH replacement improved body composition, bone mass and serum lipid profile without any between-group differences, except for a marginally more beneficial response in serum TG level in the IRR patients. After 10 years, there was no between-group difference in any variable after correction for a higher replacement dose of glucocorticoids in the IRR patients at study end using an analysis of covariance. During the 10-year GH replacement, 5 IRR patients suffered from vascular events (2 fatal) whereas only one non-fatal vascular event occurred in the non-IRR patients. CONCLUSIONS IRR patients with GHD display a more severely impaired cardiovascular risk profile at baseline, which was reversed by the 10-year GH replacement after correction for the higher glucocorticoid dose at study end. However, vascular events occurred more frequently in the IRR patients.

Abstract
Radiotherapy for pituitary adenomas is a well-established and effective treatment, but it has been linked to a number of complications, including an increased risk of cerebrovascular disease and mortality. Possible underlying mechanisms include the direct effects of radiation on cerebral vasculature and deficiencies in specific pituitary hormones. Higher administered dose of radiotherapy is one of the main predictors of stroke. Although treatment strategies for stroke prevention in patients treated with pituitary radiotherapy have not been studied, using the lowest effective radiation dose and ensuring hormone deficiencies are adequately treated may be beneficial in reducing the risk of stroke.

Abstract
OBJECTIVE The hippocampus and prefrontal cortex (PFC) are important for memory and executive functioning and are known to be sensitive to radiotherapy (RT). Radiation dosimetry relates radiation exposure to specific brain areas. The effects of various pituitary RT techniques were studied by relating detailed dosimetry of the hippocampus and PFC to cognitive performance. METHODS In this cross-sectional design, 75 non-functioning pituitary macroadenoma (NFA) patients (61±10 years) participated and were divided into irradiated (RT+, n=30) and non-irradiated (RT-, n=45) groups. The RT+ group (who all received 25 fractions of 1.8 Gy; total dose: 45 Gy) consisted of three RT technique groups: three-field technique, n=10; four-field technique, n=15; and five-field technique, n=5. Memory and executive functioning were assessed by standardized neuropsychological tests. A reconstruction of the dose distributions for the three RT techniques was made. The RT doses on 30, 50, and 70% of the volume of the left and right hippocampus and PFC were calculated. RESULTS Cognitive test performance was not different between the four groups, despite differences in radiation doses applied to the hippocampi and PFC. Age at RT, time since RT, and the use of thyroid hormone varied significantly between the groups; however, they were not related to cognitive performance. CONCLUSION This study showed that there were no significant differences on cognitive performance between the three-, four-, and five-field RT groups and the non-irradiated patient group. A dose-response relationship could not be established, even with a radiation dose that was higher on most of the volume of the hippocampus and PFC in case of a four-field RT technique compared with the three- and five-field RT techniques.

Abstract
Radiotherapy (RT) remains an effective treatment in patients with acromegaly refractory to medical and/or surgical interventions, with durable tumor control and biochemical remission; however, there are still concerns about delayed biochemical effect and potential late toxicity of radiation treatment, especially high rates of hypopituitarism. Stereotactic radiotherapy has been developed as a more accurate technique of irradiation with more precise tumour localization and consequently a reduction in the volume of normal tissue, particularly the brain, irradiated to high radiation doses. Radiation can be delivered in a single fraction by stereotactic radiosurgery (SRS) or as fractionated stereotactic radiotherapy (FSRT) in which smaller doses are delivered over 5-6 weeks in 25-30 treatments. A review of the recent literature suggests that pituitary irradiation is an effective treatment for acromegaly. Stereotactic techniques for GH-secreting pituitary tumors are discussed with the aim to define the efficacy and potential adverse effects of each of these techniques.

Abstract
BACKGROUND AND IMPORTANCE We present a rare case of a patient with intrasellar salivary gland-like pleomorphic adenoma and review the 2 previously reported cases of the clinical entity to identify their common clinical features. CLINICAL PRESENTATION A 56-year-old Asian man visited our hospital with a chief complaint of visual disturbance caused by brain tumor that filled up the sella turcica with suprasellar extension. The patient underwent craniotomy via a left pterional approach, and the subdural, intracranial portion of the tumor was totally removed, with every artery and nerve preserved. Pathological diagnosis of the tumor was intrasellar salivary gland-like pleomorphic adenoma. Three years after the operation, the patient remains free from tumor recurrence. CONCLUSION Tumors in all 3 reported cases of intrasellar salivary gland-like pleomorphic adenoma, including the present case, showed suprasellar extension and compressed optic chiasm that resulted in visual disturbance of the patients. A calcified region inside the tumor on computed tomographic scanning was also a common finding. Differential diagnosis of intrasellar salivary gland-like pleomorphic adenomas should be considered in patients with calcified intrasellar tumors with suprasellar extension. The clinical entity seems to show good prognosis if surgically removed.

Abstract
In selection of the right treatment for a specific patient, the surgeon should consider not only the best approach to remove a tumor but also the impact of treatment on the quality of life (QOL) of the patient. Procedures involving extirpation of skull base tumors may be associated with high morbidity. It is therefore important to study patients with skull base neoplasms, because survival differences between various treatment modalities may be small, yet larger differences are expected regarding morbidity. The overall QOL in the majority of patients after skull base tumor resection can be classified as "good," with significant improvement taking place within 12 months following surgery. Patients with carcinomas, acoustic schwannoma, or Cushing's disease suffer from more significant deterioration in their QOL after any intervention. Data retrieved from disease-specific questionnaires revealed that the financial and emotional domains have the worse impact on patients QOL. Old age, malignancy, comorbidity, radiotherapy, and extensive surgery were found to be also negative prognostic factors for QOL. Pain control regimens, antidepressants, and other psychological modalities, including group support, can improve QOL measures in these patients. It is critical that surgeons understand that they cannot assess their patients' perspectives on QOL correctly without asking them. For adequate assessment, validated disease-specific instruments addressing multiple domains of QOL should be utilized.

Abstract
CONTEXT AND OBJECTIVE Cognitive deterioration is reported in patients with a nonfunctioning pituitary macroadenoma (NFA) and after pituitary radiotherapy. However, reported results are inconsistent and are potentially confounded by different underlying pituitary disorders. The aim of this study was to examine cognitive functions in patients previously treated for NFA with or without radiotherapy. DESIGN Verbal memory was assessed with the Dutch equivalent to the Rey Auditory Verbal Learning Test (15 Words Test, 15 WT). Executive functioning was examined using the Ruff Figural Fluency Test (RFFT). We compared our patient cohort with large reference populations representative of the Dutch population. PATIENTS Eighty-four patients (62±10 years) who underwent transsphenoidal surgery 8.6±6.3 years earlier participated. Patients who underwent radiotherapy (n=39) were compared to those who received surgery alone (n=45). All patients were on stable hormonal replacement therapy. RESULTS The total patient group scored significantly below the reference sample on all 15 WT z-scores (95%CI): short-term memory, -0.3 (-0.5 to -0.1); total memory, -0.8 (-1.1 to -0.5); learning score, -0.3 (-0.5 to -0.1); delayed memory, -0.8 (-1.1 to -0.5), all P<0.01. The total patient group scored significantly below the reference sample on RFFT z-scores (95%CI): unique designs, -0.7 (-0.9 to -0.5) and perseverative errors, -0.5 (-0.8 to -0.2), both P<0.001. Patients who underwent radiotherapy showed no significant differences on cognition when compared to those who received surgery alone. CONCLUSION Patients with NFA score significantly worse on cognition compared to reference populations. Radiotherapy does not appear to have a major influence on cognition.

Abstract
AbstractRadiosensitive neurogenic stem cells reside in the hippocampi, suggesting that avoidance of the hippocampi may be an important strategy to reduce potential radiation-related cognitive effects. Six patients treated for base of skull tumours were re-planned using co-planar helical fan beam arc therapy (tomotherapy) and co-planar and non-coplanar volumetric arc techniques (RapidArc). The hippocampi were contoured as avoidance structures with the specific goal of minimising the dose. Two gross target volume (GTV) to planning target volume (PTV) expansions (10 and 2 mm) were considered to evaluate the impact of margin selection on organ at risk (OAR) sparing. The dose prescription was 50 Gy to >95% of the PTV. Comparison of the hippocampus avoidance plans demonstrated the importance of non-coplanar delivery when the 10 mm margin was used. With the 2 mm margin, both co-planar and non-coplanar delivery provided similar degrees of sparing. A mean dose of 3–4 Gy and a V6Gy <5% to the hippocampi was realised with the hippocampus sparing techniques. Our comparisons suggest interventions to minimise GTV to PTV margins will have a more profound influence on multiple OAR sparing than the choice of intensity modulated arc delivery technique.

Abstract
CONTEXT A number of retrospective studies report that patients with acromegaly have increased morbidity and premature mortality, with standardized mortality ratios (SMR) of 1.3-3. Many patients with acromegaly develop hypopituitarism as a result of the pituitary adenoma itself or therapies such as surgery and radiotherapy. Pituitary radiotherapy and hypopituitarism have also been associated with an increased SMR. METHODS Using the West MIDLANDS: Acromegaly database (n = 501; 275 female), we assessed the influence of prior radiotherapy and hypopituitarism (and replacement therapy) on mortality in patients with acromegaly. Median duration of follow-up was 14.0 yr (interquartile range, 7.9-21 yr). RESULTS All-cause mortality was elevated [SMR, 1.7 (1.4, 2.0); P < 0.001]. On external analysis, prior radiotherapy, ACTH, and gonadotropin deficiency were associated with an elevated SMR [radiotherapy SMR, 2.1 (1.7-2.6); P = 0.006; ACTH deficiency SMR, 2.5 (1.9-3.2); P < 0.0005; and gonadotropin deficiency SMR, 2.1 (1.6-2.7); P = 0.037]. On internal analysis, the relative risk (RR) of mortality was increased in the radiotherapy [RR, 1.8 (1.2-2.8); P = 0.008] and ACTH-deficiency groups [RR, 1.7 (1.2-2.5); P = 0.004], but not in the gonadotropin- or TSH-deficiency groups. In the ACTH-deficient group, increased replacement doses of hydrocortisone greater than 25 mg/d were associated with increased mortality compared to lower doses. CONCLUSIONS Radiotherapy and ACTH deficiency are significantly associated with increased mortality in patients with acromegaly. In ACTH-deficient patients, a daily dose of more than 25 mg hydrocortisone is associated with increased mortality compared to lower doses. These results have important implications for the treatment of patients with acromegaly and also raise issues as to the optimum hydrocortisone treatment regimens for ACTH-deficient patients.

Abstract
The management of patients with pituitary tumours requires a multidisciplinary approach utilizing a number of different treatment modalities that can impact upon pituitary function and may disrupt important areas of cerebral tissue that are important for normal neurocognitive function. Patients frequently report problems with memory and sustained attention that impact upon normal day-to-day life. At present it is unclear whether any causal link exists between treatments for pituitary tumours and abnormalities of memory and higher mental function. The domains of function affected in patients with pituitary tumours are memory and executive functions, which are involved in the control and direction of lower level, more automatic functions such as attention and motor skills. The evidence for disruption in these modalities is stronger for memory than for executive function. This may be due to variability in study design, insufficient tests and the potential inclusion of fundamentally different tumour types. The purpose of this review is to examine the available evidence to determine whether pituitary disease, its management, or subsequent complications are responsible for any neuropsychological deficits in pituitary patients. Furthermore we address methodological issues that may account for the apparent disparate neurocognitive data that exist in this patient group.

Abstract
External beam radiotherapy has been used in the management of pituitary adenomas for nearly a century, preventing tumor regrowth following surgery for non-functioning pituitary adenomas and suppressing functional hypersecretion in those which are hormonally active. However, it has been linked with a number of potentially significant complications including formation of secondary intracranial tumors, cognitive impairment, hypopituitarism and cerebrovascular disease, as well as increased mortality. Radiation may cause a variety of vascular injuries and hemodynamic changes to the cerebral vasculature, and several authors have reported cerebrovascular complications and an increase in cerebrovascular mortality in patients receiving radiotherapy for pituitary and other central nervous system tumors. Ten years following pituitary radiotherapy, over 50% of patients develop deficiencies in one or more anterior pituitary hormones. A number of studies have demonstrated increased mortality in patients with hypopituitarism, predominantly due to cerebrovascular and cardiovascular disease. However, no clear answer has emerged with regards to causation, and pituitary radiotherapy has only been linked directly to mortality in one of these studies. Questions remain unanswered, and the use of conventional external beam radiotherapy in the management of pituitary disease must involve a critical risk-benefit analysis in each case.

Abstract
Growth-hormone hypersecretion, acromegaly, is associated with reduced life expectancy. First line treatment remains surgery, but remission rates vary between 50% and 90%. In case of lack of surgical remission or recurrence, somatostatin agonists can be proposed. However, about 30% of patients are partially or totally resistant to this treatment. The growth hormone receptor antagonist pegvisomant currently needs more prolonged follow-up studies. Conventional radiotherapy and radiosurgery are two radiation treatment modalities that can be proposed to these resistant patients. Reported rates of remission for conventional radiotherapy range between 50% and 60% in patients with acromegaly, with a time to remission delayed by several years, and adverse effects including high rates of hypopituitarism. This treatment could be proposed to patients with aggressive adenomas, in whom surgery cannot allow biochemical control. In contrast, studies on stereotactic radiosurgery reported lower rates of remission, with faster growth hormone hypersecretion decline, and a lower risk of adverse effects. However, this latter technique requires a well defined target volume, which limits its indications. The high precision of this technique makes it possible to be used as an alternative primary treatment to surgery. We reviewed major advantages and drawbacks of each of these techniques, based on recent studies to try to define their respective indications in the therapeutic algorithm of acromegaly.

Abstract
OBJECTIVE To verify whether patients with pituitary disorders in remission and on appropriate treatment display significant differences in psychological distress compared to healthy controls and other patients treated for nonpituitary endocrine disorders. DESIGN A single-centred, controlled study. PATIENTS Eighty-six outpatients cured or in remission for at least 9 months following appropriate treatment by surgery, irradiation and/or pharmacological interventions for pituitary disease were compared with 86 healthy subjects. A sample comprising 60 outpatients cured or in remission from nonpituitary endocrine disorders was also compared. MEASUREMENTS (1) A modified version of the Structural Clinical Interview for DSM-IV; (2) a shortened version of the structured interview for the Diagnostic Criteria for Psychosomatic Research (DCPR); (3) the Psychosocial Index (PSI); and (4) the Medical Outcomes Study (MOS) short form General Health Survey (SF-20) were employed. RESULTS Patients with pituitary disease displayed a higher prevalence of psychiatric disease (P < 0.001) compared to controls, but not when compared to nonpituitary endocrine patients. They also showed a higher prevalence of DCPR clusters compared to controls (P < 0.001), but not when compared to nonpituitary endocrine patients. At PSI and MOS (SF-20), patients with endocrine disease, whether pituitary or not, reported more psychological distress, and less well-being (P < 0.001) compared to controls. CONCLUSIONS At follow-up after appropriate treatment, we documented a high prevalence of psychopathology in patients with pituitary disease, which was however, similar to that found in nonpituitary endocrine patients. This is consistent with an increasing body of literature that reports difficulties in obtaining full recovery in patients treated for endocrine disorders.

Gamma knife radiosurgery for patients with nonfunctioning pituitary adenomas: results from a 15-year experience. Int J Radiat Oncol Biol Phys 2007; 70:1325-9. [PMID: 18029107 DOI: 10.1016/j.ijrobp.2007.08.018] [Citation(s) in RCA: 140] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2007] [Revised: 08/14/2007] [Accepted: 08/16/2007] [Indexed: 11/15/2022]
Abstract
PURPOSE To evaluate the efficacy and complications of stereotactic radiosurgery for patients with nonfunctioning pituitary adenomas (NFA). METHODS AND MATERIALS This was a retrospective review of 62 patients with NFA undergoing radiosurgery between 1992 and 2004, of whom 59 (95%) underwent prior tumor resection. The median treatment volume was 4.0 cm(3) (range, 0.8-12.9). The median treatment dose to the tumor margin was 16 Gy (range, 11-20). The median maximum point dose to the optic apparatus was 9.5 Gy (range, 5.0-12.6). The median follow-up period after radiosurgery was 64 months (range, 23-161). RESULTS Tumor size decreased for 37 patients (60%) and remained unchanged for 23 patients (37%). Two patients (3%) had tumor growth outside the prescribed treatment volume and required additional treatment (fractionated radiation therapy, n = 1; repeat radiosurgery, n = 1). Tumor growth control was 95% at 3 and 7 years after radiosurgery. Eleven (27%) of 41 patients with normal (n = 30) or partial (n = 11) anterior pituitary function before radiosurgery developed new deficits at a median of 24 months after radiosurgery. The risk of developing new anterior pituitary deficits at 5 years was 32%. The 5-year risk of developing new anterior pituitary deficits was 18% for patients with a tumor volume of < or = 4.0 cm(3) compared with 58% for patients with a tumor volume >4.0 cm(3) (risk ratio = 4.5; 95% confidence interval = 1.3-14.9, p = 0.02). No patient had a decline in visual function. CONCLUSIONS Stereotactic radiosurgery is effective in the management of patients with residual or recurrent NFA, although longer follow-up is needed to evaluate long-term outcomes. The primary complication is hypopituitarism, and the risk of developing new anterior pituitary deficits correlates with the size of the irradiated tumor.

Does Intensity Modulation Improve Healthy Tissue Sparing in Stereotactic Radiosurgery of Complex Arteriovenous Malformations? Med Dosim 2007; 32:172-80. [PMID: 17707196 DOI: 10.1016/j.meddos.2006.12.002] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2006] [Accepted: 12/14/2006] [Indexed: 10/22/2022]
Abstract
This planning study evaluates the potential of intensity modulated treatment fields and inverse planning techniques in stereotactic radiosurgery to reduce healthy tissue dose. Twenty patients previously treated with stereotactic radiosurgery for arteriovenous malformation (AVM) were replanned with each of 4 techniques: circular non-coplanar arcs, dynamic arcs, static conformal fields, and intensity modulated radiosurgery (IMRS). Patients were selected having a maximum AVM dimension at least 20 mm, or volume greater than 10 cm(3). Target volumes ranged from 2.12 cm(3) to 13.87 cm(3) with a median of 6.03 cm(3). Resulting dose distributions show a statistically significant improvement in target conformality between circular arcs and all other techniques (p </= 0.001), between conformal and both dynamic arcs and IMRS (p </= 0.03) and with no difference between dynamic arcs and IMRS. However, for AVMs of volume greater than 5.5 cm(3), IMRS gives better conformality than dynamic arcs (p = 0.04). IMRS showed consistently lower dose inhomogeneity compared to both dynamic arcs and conformal fields (p < 0.001). At low dose levels, the dynamic arc technique irradiates less healthy tissue than the other techniques (p </= 0.001). Both dynamic arcs and IMRS provide increased ability to conform to the AVM, with IMRS showing greater ability to control dose at the periphery.

Abstract
PURPOSE To assess the influence of different treatment modalities on long-term health-related quality of life (HR-QoL) and cognitive problems among patients who had been treated for nonfunctioning pituitary adenoma (NFA). METHODS AND MATERIALS Eighty-one patients (49 men and 32 women, aged 55 +/- 10 years) with a minimal follow-up period of 1 year after treatment for NFA participated in this cross-sectional study. Sixty-two patients were initially treated by transsphenoidal surgery and 19 by craniotomy. Subsequently, 45 of these 81 subjects (56%) received additional radiotherapy (RT) after surgery because of a tumor remnant or regrowth. All subjects filled in standardized questionnaires measuring HR-QoL, depression, fatigue, and cognitive problems. RESULTS Patients who underwent additional RT more frequently underwent a craniotomy and were younger at surgery, but not at entering this study. They also used more hormonal substitution. Most HR-QoL domains showed a similar score in patients who underwent RT when compared with patients who did not receive RT. However, vitality and physical functioning proved to be better in RT subjects, and RT subjects also had better scores for depression and physical and mental fatigue (all p < 0.05). Some aspects of HR-QoL of patients who have been successfully treated for NFA are reduced compared with the normal population, but this was much more pronounced in the group that did not receive RT. In multivariate analysis, RT remained significantly associated with improved HR-QoL. No differences in cognitive function scores were observed. CONCLUSION Postoperative RT in patients with NFA is not associated with reduced quality of life or cognition when compared with surgery alone.

Immediate postoperative radiotherapy in residual nonfunctioning pituitary adenoma: Beneficial effect on local control without additional negative impact on pituitary function and life expectancy. Int J Radiat Oncol Biol Phys 2007; 67:863-9.

Abstract
PURPOSE To demonstrate the benefit of immediate postoperative radiotherapy in residual nonfunctioning pituitary adenoma (NFA) in perspective to the need for hormonal substitution and life expectancy. METHODS AND MATERIALS Retrospective cohort analysis of 122 patients, operated for NFA between 1979 and 1998. Recurrence was defined as regrowth on computed tomography or magnetic resonance imaging. The occurrence of hormonal deficiencies was defined as the starting date of hormonal substitution therapy. RESULTS Seventy-six patients had residual NFA after surgery and received immediate postoperative radiotherapy (Group 1); three patients developed a recurrence, resulting in a 95% local control rate at 10 years. Twenty-eight patients had residual NFA after surgery, but were followed by a wait-and-see policy (Group 2). Sixteen developed a recurrence, resulting in a local control rate of 49% at 5 years and 22% at 10 years (p < 0.001 compared with Group 1). There were no differences between Group 1 and 2 regarding the need for substitution with thyroid hormone, glucocorticoids, and sex hormones before first surgery, directly after surgery and at end of follow-up. There were no differences in hormone substitution free survival between Group 1 and Group 2 during the study period after first surgery. Life expectancy was similar in Group 1 and 2, and their median life expectancy did not differ from median life expectancy in the general population. CONCLUSIONS Immediate postoperative radiotherapy provides a marked improvement of local control among patients with residual NFA compared with surgery alone, without an additional deleterious effect on pituitary function and life expectancy.

Abstract
BACKGROUND AND AIMS The aim of the present study was to evaluate the clinical presentation, characteristics and post-surgical outcome of non-functioning pituitary macroadenomas (NFPM) in elderly patients. METHODS 27 patients (65-81 years; 13 Males, 14 Females) with NFPM (20-45 mm in diameter) were studied. The symptoms prompting neuroradiological studies were vision alterations in 52%, and dizziness, loss of memory, confusion, headache and depression in 29%; in 19% of patients, the disease was incidentally discovered during computed tomography (CT) or magnetic resonance imaging (MRI) for head trauma or cerebral ischemic attacks. RESULTS Endocrinological evaluation on diagnosis showed global anterior hypopituitarism in 33% and partial hypopituitarism in 37% of patients. Immunohistochemistry showed signs of neurosecretion in most NFPM (chromogranin-A in 55%, gonadotropins in 19%, ACTH in 3.7%). Ki-67 antigen expression was indicative of low proliferative activity. Surgery was highly effective in improving alterations in vision and compressive symptoms, but was unable to restore normal pituitary function in established hypopituitarism in most cases. Eight patients (31%) were free of disease on subsequent MRI (follow-up 1-6 years). In 18 (69%) patients, a post-surgical residue was present. Of these, 6 (33%) underwent radiotherapy in the following years, owing to an increase in the volume of the remnants, and six (33%) underwent additional surgical treatment, followed by radiotherapy for further signs of growth in two. In the remaining patients, a small intrasellar remnant was stable on yearly MRI. CONCLUSIONS in elderly patients, the development of hypopituitarism is often overlooked and the initial diagnosis of NFPM may be delayed. This can expose patients to the risks of unrecognized hypopituitarism and jeopardize post-surgical outcome.

Abstract
Growth hormone (GH) is synthesised and secreted by the somatotroph cells of the anterior lobe of the pituitary gland. Its actions involve multiple organs and systems, affecting postnatal longitudinal growth as well as protein, lipid, and carbohydrate metabolism. GH hypersecretion results in gigantism or acromegaly, a condition associated with significant morbidity and mortality, while GH deficiency results in growth retardation in children and the GH deficiency syndrome in adults. This article, aimed at non-paediatric physicians, examines the clinical features, diagnosis, and current concepts in the management of these conditions.

Abstract
PURPOSE OF REVIEW The neurocognitive sequelae of anticancer treatment have received increasing attention especially among individuals with low-grade gliomas, primary central nervous system lymphoma and those undergoing prophylactic cranial irradiation for systemic malignancies. These groups are especially vulnerable because they often experience extended survival during which neurocognitive complications of therapy may cause more impairment than the tumor itself. The purpose of this review is to highlight recent clinical reports of neurocognitive sequelae among patients without significant central nervous system tumor burden and to describe the experimental studies which may explain the pathogenesis of the disorder. RECENT FINDINGS The neurocognitive deficits among survivors of primary central nervous system lymphoma without residual tumor and pituitary tumors were reported recently. Both provide an opportunity to distinguish the effects of treatment from the effects of tumor. Moreover, animal studies demonstrate the negative consequences of radiation on hippocampal neurogenesis, learning and memory. The mechanism of impaired neurogenesis may be due to inflammation, which can be aborted with restoration of neurogenesis through the administration of non-steroidal anti-inflammatory agents. SUMMARY If inhibition of neurogenesis is the basis of neurocognitive sequelae from irradiation and non-steroidal anti-inflammatory agents can restore neurogenesis then a clinical trial may be worthwhile to confirm this benefit in humans.

Abstract
External beam radiotherapy has been used extensively in the management of patients with pituitary disease. However, in view of advances in the techniques of radiotherapy planning and administration, neurosurgery and pharmacological manipulation of the pituitary, there are a growing number of questions and controversies surrounding the current and future use of pituitary radiotherapy in the management of pituitary disease.
