Abstract
PURPOSE Variants in the Aryl hydrocarbon receptor-interacting protein (AIP) gene have been identified in sporadic acromegaly and pituitary gigantism, especially in young patients, with a predisposition to aggressive clinical phenotype and poor treatment efficacy. The clinical characteristics of patients with sporadic acromegaly and pituitary gigantism as well as AIP variants in Han Chinese have been rarely reported. We aimed to identify AIP gene variants and analyze the clinical characteristics of patients with sporadic acromegaly and pituitary gigantism in Han Chinese. METHODS The study included 181 sporadic acromegaly (N = 163) and pituitary gigantism (N = 18) patients with an onset age of no more than 45 years old, who were diagnosed, treated, and followed up in Huashan Hospital. All 6 exons and their flanking regions of the AIP gene were analyzed with Sanger sequencing or NGS. The clinical characteristics were compared between groups with and without AIP variants. RESULTS Germline AIP variants were found in 15/181 (8.29%) cases. In patients with an onset age ≤30 years old, AIP variants were identified in 12/133 (9.02%). Overall, 13 variants were detected. The pathogenic (P) variants p.R304X and p.R81X were identified in four cases, with two instances of each variant. Six exon variants (p.C254R, p.K103fs, p.Q228fs, p.Y38X, p.Q213*, and p.1115 fs) have not been reported before, which were likely pathogenic (LP). Patients with P/LP variants had younger onset ages, a higher prevalence of pituitary gigantism, larger tumor volumes, and a higher percentage of Ki-67-positive cells in tumors. In addition, the group with P/LP variants showed a less significant reduction of GH levels in an acute octreotide suppression test (OST) [17.7% (0, 65.0%) vs. 80.5% (63.9%, 90.2%), P = 0.001], and a trend of less GH decrease after the 3-month treatment with long-acting somatostatin analogs (SSAs). CONCLUSION Germline AIP variants existed in sporadic Chinese Han acromegaly and pituitary gigantism patients and were more likely to be detected in young patients. AIP variants were associated with more aggressive tumor phenotypes and less response to SSA treatment.

Integrative clinical, hormonal, and molecular data associate with invasiveness in acromegaly: REMAH study. Eur J Endocrinol 2024; 190:421-433. [PMID: 38701338 DOI: 10.1093/ejendo/lvae045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Revised: 02/18/2024] [Accepted: 03/04/2024] [Indexed: 05/05/2024]
Abstract
INTRODUCTION Growth hormone (GH)-secreting pituitary tumors (GHomas) are the most common acromegaly cause. At diagnosis, most of them are macroadenomas, and up to 56% display cavernous sinus invasion. Biomarker assessment associated with tumor growth and invasion is important to optimize their management. OBJECTIVES The study aims to identify clinical/hormonal/molecular biomarkers associated with tumor size and invasiveness in GHomas and to analyze the influence of pre-treatment with somatostatin analogs (SSAs) or dopamine agonists (DAs) in key molecular biomarker expression. METHODS Clinical/analytical/radiological variables were evaluated in 192 patients from the REMAH study (ambispective multicenter post-surgery study of the Spanish Society of Endocrinology and Nutrition). The expression of somatostatin/ghrelin/dopamine system components and key pituitary/proliferation markers was evaluated in GHomas after the first surgery. Univariate/multivariate regression studies were performed to identify association between variables. RESULTS Eighty percent of patients harbor macroadenomas (63.8% with extrasellar growth). Associations between larger and more invasive GHomas with younger age, visual abnormalities, higher IGF1 levels, extrasellar/suprasellar growth, and/or cavernous sinus invasion were found. Higher GH1 and lower PRL/POMC/CGA/AVPR1B/DRD2T/DRD2L expression levels (P < .05) were associated with tumor invasiveness. Least Absolute Shrinkage and Selection Operator's penalized regression identified combinations of clinical and molecular features with areas under the curve between 0.67 and 0.82. Pre-operative therapy with DA or SSAs did not alter the expression of any of the markers analyzed except for DRD1/AVPR1B (up-regulated with DA) and FSHB/CRHR1 (down-regulated with SSAs). CONCLUSIONS A specific combination of clinical/analytical/molecular variables was found to be associated with tumor invasiveness and growth capacity in GHomas. Pre-treatment with first-line drugs for acromegaly did not significantly modify the expression of the most relevant biomarkers in our association model. These findings provide valuable insights for risk stratification and personalized management of GHomas.

Abstract
PURPOSE Acromegalic patients with giant growth hormone-secreting pituitary adenomas (GHPAs) (≥ 40 mm) are relatively rare, and their clinical characteristics and treatment outcome data are limited. This study aims to analyze the clinical practice experience of giant GHPAs. METHODS Sixty-seven acromegalic patients with giant GHPAs and 67 patients with macro GHPAs (10-39 mm), matched for age and gender from the same hospital during the same period, were retrospectively recruited. The clinical characteristics, treatment, and outcomes were analyzed. RESULTS Enlargement of the extremities and facial features were the most common symptoms in most patients (92.5%). Compared with the macroadenoma group, more frequent visual impairment (86.6% vs. 25.4%, P < 0.001) and gonadal axis dysfunction (49.3% vs. 34.3%, P = 0.008), higher preoperative fasting GH, nadir GH after OGTT and IGF-1 levels, and a higher proportion of extrasellar tumor invasion were seen in the giant adenoma group. As the adenoma size increases, the total resection rate decreases, and postoperative complications and multimodal treatment strategies increase significantly. Fasting and nadir GH levels remained higher at 1 week postoperatively, and there were more surgical complications and cases of anterior hypopituitarism in the giant group. After a median follow-up of 36 months, 12 patients (36.4%) in the giant GHPA group and 17 (36.2%) in the macro GHPA group achieved biochemical remission. Other factors such as age of onset, age of diagnosis, delayed diagnosis time, metabolic complications, p53 positive rate, and Ki-67 index showed no significant difference between the two groups. CONCLUSIONS With aggressive multimodal therapy, the biochemical remission rate of acromegalic patients with giant GHPAs is comparable to that of patients with macro adenoma. However, postoperative complications and hypopituitarism need to be closely monitored.

Abstract
OBJECTIVE Current studies on the effect of high growth hormone (GH)/insulin-like growth factor (IGF)-1 on thyroid function are inconsistent. The aim was to explore the effect and potential mechanism of high GH/IGF-1 on thyroid function by analyzing the changes of thyroid function in patients with growth hormone-secreting pituitary adenoma (GHPA). METHODS This was a retrospective cross-sectional study. Demographic and clinical data of 351 patients with GHPA who were first admitted to Beijing Tiantan Hospital, Capital Medical University, from 2015 to 2022 were collected to analyze the relationship between high GH/IGF-1 levels and thyroid function. RESULTS GH was negatively correlated with total thyroxine (TT4), free thyroxine (FT4), and thyroid-stimulating hormone (TSH). IGF-1 was positively correlated with total triiodothyronine (TT3), free triiodothyronine (FT3), and FT4 and negatively correlated with TSH. Insulin-like growth factor-binding protein (IGFBP)-3 was positively correlated with TT3, FT3, and FT3:FT4 ratio. The FT3, TT3, TSH, and FT3:FT4 ratio of patients with GHPA and diabetes mellitus (DM) were significantly lower than those with GHPA but without DM. With the increase of tumor volume, thyroid function gradually decreased. GH and IGF-1 were correlated negatively with age in patients with GHPA. CONCLUSION The study emphasized the complex interaction between the GH and the thyroid axes in patients with GHPA and highlighted the potential effect of glycemic status and tumor volume on thyroid function.

Abstract
CONTEXT Invasive and somatostatin receptor ligand (SRL)-resistant pituitary tumors represent a challenge in the clinical practice of endocrinologists. Efforts have been made to elucidate reliable makers for both. Survivin and eukaryotic translation initiation factor-binding protein 1 (4EBP1) are upregulated in several cancers and involved in apoptosis and cell proliferation. OBJECTIVE We explored the role of these markers in somatotropinomas. METHODS Immunostains for survivin and 4EBP1, and also for somatostatin receptor type 2 (SSTR2), Ki-67, and cytokeratin 18, were analyzed in tissue microarrays containing 52 somatotropinoma samples. Tumor invasiveness was evaluated in all samples while drug resistance was evaluated in 34 patients who received SRL treatment. All these parameters were correlated with first-generation SRL (fg-SRL) responsiveness and tumor invasiveness. RESULTS Low survivin expression (P = 0.04), hyperintense signal on T2 weighted image (T2WI) (P = 0.01), younger age (P = 0.01), sparsely granular adenomas (SGA) (P = 0.04), high postoperative growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels (P = 0.049 and P < 0.001, respectively), and large postoperative tumor size (P = 0.02) were associated with resistance to fg-SRL. Low survivin and SSTR2 expression and high 4EBP1 expression were associated with SGA (P = 0.04, P = 0.01, and P = 0.001, respectively). Younger age (P = 0.03), large tumor pre- and postoperative (P = 0.04 and P = 0.006, respectively), low SSTR2 expression (P = 0.03), and high baseline GH and IGF-1 (P = 0.01 and P = 0.02, respectively) were associated with tumor invasiveness. However, survivin, 4EBP1, Ki-67, and granulation patterns were not associated with tumor invasion. CONCLUSION This study suggests that low survivin expression is predictive of resistance to fg-SRL in somatotropinomas, but not of tumor invasiveness.

Abstract
OBJECTIVES Since giant (≥40 mm) GH-secreting pituitary adenomas are rarely encountered, data on their characteristics and treatment outcomes are limited. We aimed to investigate the characteristics of giant GH-secreting pituitary adenomas and to compare their clinical, biochemical, imaging and histopathological features with non-giant macroadenomas. MATERIALS AND METHODS We have evaluated 15 (six female/nine male) and 57 (29 female/28 male) patients with acromegaly in giant and <40 mm adenoma groups, respectively. Patients with <40 mm adenoma were further divided into subgroups with adenoma size 20-29 mm and 30-39 mm. RESULTS In giant adenoma group, median (IQR) preoperative maximal diameter of adenoma was 40 mm (5 mm), median preoperative GH level was 40 (153.4) ng/mL and median baseline IGF-1 level was 2.19 (1.88) × ULN for age and sex. The number of surgeries was significantly higher in giant adenoma group (median 2, IQR 2) in which 66.7% of patients underwent repeated surgeries (p = 0.014). Residual tumor was detected after last operation in all patients with giant adenoma. Total number of treatment modalities administered postoperatively increased as adenoma size increased (p = 0.043). After a median follow-up duration of 10 years (IQR 10), hormonal remission was achieved in six patients (40%) of giant adenoma group, while the rate of hormonal remission in non-giant adenoma group was 37%. Although preoperative GH and IGF-1 levels and Ki-67 index tended to be higher with increasing adenoma size, there was no statistically significant difference between groups in terms of these variables, as well as age, sex and invasion status. CONCLUSION Hormonal remission rates of acromegaly patients with ≥20 mm pituitary macroadenoma were comparable. However, giant GH-secreting pituitary adenomas require an aggressive multimodal treatment approach.

Factors associated with therapeutic response in acromegaly diagnosed in the elderly in Spain. Front Endocrinol (Lausanne) 2022; 13:984877. [PMID: 36187107 PMCID: PMC9523598 DOI: 10.3389/fendo.2022.984877] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2022] [Accepted: 08/30/2022] [Indexed: 11/13/2022] Open
Abstract
CONTEXT Some reports suggest that acromegaly in elderly patients has a more benign clinical behavior and could have a better response to first-generation long-acting somatostatin receptor ligands (SRL). However, there is no specific therapeutic protocol for this special subgroup of patients. OBJECTIVE This study aimed at identifying predictors of response to SRL in elderly patients. DESIGN Multicentric retrospective nationwide study of patients diagnosed with acromegaly at or over the age of 65 years. RESULTS One-hundred and eighteen patients (34 men, 84 women, mean age at diagnosis 71.7 ± 5.4 years old) were included. Basal insulin-like growth factor type 1 (IGF-1) above the upper limit of normal (ULN) and growth hormone (GH) levels (mean ± SD) were 2.7 ± 1.4 and 11.0 ± 11.9 ng/ml, respectively. The mean maximal tumor diameter was 12.3 ± 6.4 mm, and up to 68.6% were macroadenoma. Seventy-two out of 118 patients (61.0%) underwent surgery as primary treatment. One-third of patients required first-line medical treatment due to a rejection of surgical treatment or non-suitability because of high surgical risk. After first-line surgery, 45/72 (63.9%) were in disease remission, and 16/34 (46.7%) of those treated with SRL had controlled disease. Patients with basal GH at diagnosis ≤6 ng/ml had lower IGF-1 levels and had smaller tumors, and more patients in this group reached control with SRL (72.7% vs. 33.3%; p < 0.04) [OR: 21.3, IC: 95% (2.4-91.1)], while male patients had a worse response [OR: 0.09, IC 95% (0.01-0.75)]. The predictive model curve obtained for SRL response showed an AUC of 0.82 CI (0.71-0.94). CONCLUSIONS The most frequent phenotype in newly diagnosed acromegaly in the elderly includes small adenomas and moderately high IGF-1 levels. GH at diagnosis ≤6 ng/ml and female gender, but not age per se, were associated with a greater chance of response to SRL.

Abstract
PURPOSE To identify presurgical clinical, hormonal and radiological variables associated with surgical remission in acromegaly and develop a predictive model for surgical remission. METHODS Ambispective study of acromegaly surgical patients followed in two Spanish tertiary hospitals. Patients operated by the same neurosurgeon by endonasal endoscopic transsphenoidal approach (n = 49) were included to develop the predictive model, and patients operated by other neurosurgeons (n = 37) were used for external validation of the predictive model. The predictive model was developed with a multivariate logistic regression model based on the 2000 criteria. RESULTS 86 acromegalic patients were included. 49 patients, 83.7% with macroadenomas and 32.7% with Knosp grade > 2, were included for the development of the predictive model. The overall rate of surgical remission with the 2000 criteria was 73.5% and 51.0% with the 2010 criteria. Using the 2000 criteria, variables associated with surgical remission were: older age (OR = 1.1, p = 0.001), lower basal presurgical GH levels (OR = 0.9, p = 0.003), Knosp 0-2 (OR = 34.1, p < 0.0001) and lower maximum pituitary adenoma diameter (OR = 0.9, p = 0.019). The model with the best diagnostic accuracy to predict surgical remission combined age, Knosp 0-2 and presurgical GH levels (AIC = 29.7, AUC = 0.95) with a sensitivity of 93.8% and a specificity of 75.0%. The estimated loss of prediction with the external validation (n = 37) was 4.2%. CONCLUSION The predictive model with the best diagnosis accuracy for surgical remission combined age, Knosp 0-2 and presurgical GH levels, with a sensitivity of 93.8% and a specificity of 75.0%. This model could be very useful to select candidates to preoperative medical treatment and planning the follow-up.

Body fat distribution and circulating adipsin are related to metabolic risks in adult patients with newly diagnosed growth hormone deficiency and improve after treatment. Biomed Pharmacother 2020; 132:110875. [PMID: 33254428 DOI: 10.1016/j.biopha.2020.110875] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 10/08/2020] [Accepted: 10/09/2020] [Indexed: 01/08/2023] Open
Abstract
OBJECTIVE The relationships between body fat distribution, the adipokine adipsin and metabolic risks were assessed in patients with adult growth hormone deficiency (AGHD) before and after growth hormone (GH) treatment. METHODS Sixty newly diagnosed AGHD patients were included in our study, 24 of whom were evaluated after at least one year of GH treatment. Anthropometric parameters, glucolipid metabolism and the adipokine adipsin were measured. Visceral adipose tissue (VAT) and body composition were evaluated using a dual-energy X-ray-absorptiometry (DXA) scanner. RESULTS At baseline, the higher VAT group had worse glucolipid metabolism parameters. Basal GH was negatively associated with VAT (r=-0.277, p = 0.045), while minimal correlations were found with fat mass depots, such as limbs and trunk fat (all p > 0.05). Adipsin was correlated with total body fat (r = 0.543, p < 0.001), VAT (r = 0.563, p < 0.001) and insulin resistance (r = 0.353, p = 0.006). The effect of GH administration on fat distribution was mainly reflected in the reduction in VAT. Partial improvements were found in lipid profiles, including increased high-density lipoprotein (HDL) and decreases in triglycerides (TGs) and lipoprotein(a), while glucose metabolism showed little change. The adipsin level also decreased significantly. The best predictors of VAT at baseline were trunk fat and IGF-I, and after treatment, VAT was predicted by decreased adipsin and an increase in lean mass. CONCLUSIONS (1) VAT is an important metabolic risk factor for AGHD patients. (2) GH treatment decreased body fat predominantly in the visceral and central fat depots. (3) The lipid profiles partially improved after treatment, while glucose metabolism showed little change.

Abstract
PURPOSE To evaluate the effectiveness of cabergoline and the parameters affecting cabergoline response as add-on treatment to somatostatin analaogues (SSA) in patients with acromegaly uncontrolled with SSAs. MATERIAL AND METHOD One hundred and twenty-nine acromegalic patients uncontrolled with SSA who had cabergoline added to their treatment were included in this retrospective study. Patients were divided into the SSAs + cabergoline-responsive (group 1) and non-responsive groups (group 2), and biochemical, pathologic, and radiologic parameters were assessed. RESULTS IGF-1 normalization was achieved in 75 of 129 patients (58%) when cabergoline was added to the SSA treatment. Female patients were significantly higher in group 1 compared to group 2 (p=0.006). Group 1 had significantly smaller pre- and post-cabergoline tumor size (p=0.011, p=0.007 respectively), lower levels of IGF-1 in pre-and post-operative period (p=0.040, p=0.001), and lower levels of IGF-1 in pre- and post-cabergoline treatment (p<0.001). Cavernous invasion on sellar magnetic resonance imaging, dural invasion in pathologic examination were not significantly different between the groups. Sellar invasion in pathologic examination was significantly higher in group 1 (p=0.011). No significant difference was found in proliferation indices between two groups. The presence of fibrous bodies was significantly lower in group 1 (p=0.010). CONCLUSION Cabergoline can be added to the treatment of acromegalic patients uncontrolled with SSAs due to its ease of use and low economic cost, especially in patients with acromegaly who have small adenomas and no fibrous bodies.

Abstract
PURPOSE Biochemical control is the main determinant of survival, clinical manifestations and comorbidities in acromegaly. Transsphenoidal selective adenomectomy (TSA) is the initial treatment of choice with reported biochemical remission rates varying between 32 and 85%. Understanding the limiting factors is essential for identification of patients who require medical treatment. METHODS We reviewed the English literature published in Medline/Pubmed until Dec 31, 2019 to identify eligible studies that described outcomes of TSA as primary therapy and performed analyses to determine the main predictors of remission. RESULTS Most publications reported single-institution, retrospective studies. The following preoperative parameters were consistently associated with lower remission rates: cavernous sinus invasion by imaging, larger tumor size and higher GH levels. Young age and preoperative IGF-1 levels were predictive in some studies. When controlled for covariates, the best single preoperative predictor was cavernous sinus invasion, followed by preoperative GH levels. Conversely, low GH level in the first few days postoperatively was a robust predictor of durable remission. The influence of tumor histology (sparsely granular pattern, co-expression of prolactin and proliferation markers) on surgical remission remains to be established. Few studies developed predictive models that yielded much higher predictive values than individual parameters. CONCLUSION Surgical outcome prognostication systems could be further generated by machine learning algorithms in order to support development and implementation of personalized care in patients with acromegaly.

Abstract
CONTEXT First-generation somatostatin receptor ligands (fg-SRLs) represent the mainstay of medical therapy for acromegaly, but they provide biochemical control of disease in only a subset of patients. Various pretreatment biomarkers might affect biochemical response to fg-SRLs. OBJECTIVE To identify clinical predictors of the biochemical response to fg-SRLs monotherapy defined as biochemical response (insulin-like growth factor (IGF)-1 ≤ 1.3 × ULN (upper limit of normal)), partial response (>20% relative IGF-1 reduction without normalization), and nonresponse (≤20% relative IGF-1 reduction), and IGF-1 reduction. DESIGN Retrospective multicenter study. SETTING Eight participating European centers. METHODS We performed a meta-analysis of participant data from 2 cohorts (Rotterdam and Liège acromegaly survey, 622 out of 3520 patients). Multivariable regression models were used to identify predictors of biochemical response to fg-SRL monotherapy. RESULTS Lower IGF-1 concentration at baseline (odds ratio (OR) = 0.82, 95% confidence interval (CI) 0.72-0.95 IGF-1 ULN, P = .0073) and lower bodyweight (OR = 0.99, 95% CI 0.98-0.99 kg, P = .038) were associated with biochemical response. Higher IGF-1 concentration at baseline (OR = 1.40, (1.19-1.65) IGF-1 ULN, P ≤ .0001), the presence of type 2 diabetes (oral medication OR = 2.48, (1.43-4.29), P = .0013; insulin therapy OR = 2.65, (1.02-6.70), P = .045), and higher bodyweight (OR = 1.02, (1.01-1.04) kg, P = .0023) were associated with achieving partial response. Younger patients at diagnosis are more likely to achieve nonresponse (OR = 0.96, (0.94-0.99) year, P = .0070). Baseline IGF-1 and growth hormone concentration at diagnosis were associated with absolute IGF-1 reduction (β = 0.90, standard error (SE) = 0.02, P ≤ .0001 and β = 0.002, SE = 0.001, P = .014, respectively). CONCLUSION Baseline IGF-1 concentration was the best predictor of biochemical response to fg-SRL, followed by bodyweight, while younger patients were more likely to achieve nonresponse.

Abstract
BACKGROUND Acromegaly is a rare disease characterized by a chronic exposition to growth hormone (GH) and insulin-like growth factor-1 (IGF-1), caused in most cases by a pituitary GH-secreting adenoma. Chronic GH excess induces systemic complications (metabolic, cardiovascular, respiratory, neoplastic, and musculoskeletal) and increased mortality if not appropriately treated. Recent epidemiological data report an improved life span of patients with acromegaly probably due to better acromegaly management; additionally, the number of pituitary incidentaloma in general population also increased over time due to more frequent imaging. Therefore, the number of elderly patients, newly diagnosed with acromegaly or in follow-up, is expected to grow in the coming years and clinicians will need to be aware of particularities in managing these patients. PURPOSE This review aims to explore different aspects of acromegaly of the elderly patients, focusing on epidemiology, diagnosis, clinical presentation, complications, and management options. METHODS Available literature has been assessed through PubMed (data until August 2019) by specific keywords. CONCLUSIONS Available data on acromegaly in the elderly patient are sparse, but point to important differences. Further studies are needed comparing elderly with younger patients with acromegaly to better define a tailored diagnostic and therapeutic management.

[PMID: 31701145 PMCID: PMC8660161 DOI: 10.1210/clinem/dgz187] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2019] [Accepted: 11/06/2019] [Indexed: 02/13/2023]
Abstract
PURPOSE To determine the prevalence of insulin-like growth factor-1 (IGF-1) normalization with long-term multimodality therapy in a pituitary center and to assess changes over time. METHODS Patients with acromegaly (N = 409), with ≥1 year of data after surgery and at least 2 subsequent clinic visits were included in long-term analysis (N = 266). Biochemical data, clinical characteristics, and therapeutic interventions were reviewed retrospectively. RESULTS At diagnosis, mean [standard deviation] age was 43.4 [14.3] years, body mass index was 28.5 (24.9-32.1) kg/m2 (median, interquartile range), serum IGF-1 index (IGF-1 level/upper limit of normal) was 2.3 [1.7-3.1], and 80.5% had macroadenomas. Patients with transsphenoidal surgery after 2006 were older [46.6 ± 14.3 vs 40.0 ± 13.4 years; P < 0.001]. Age and tumor size correlated inversely. Overall (N = 266), 93.2% achieved a normal IGF-1 level during 9.9 [5.0-15.0] years with multimodality therapy. The interval to first normal IGF-1 level following failed surgical remission was shorter after 2006: 14.0 (95% confidence interval, 10.0-20.0) versus 27.5 (22.0-36.0) months (P = 0.002). Radiation therapy and second surgery were rarer after 2006: 28 (22%) versus 62 (47.0%); P < 0.001 and 12 (9.4%) versus 28 (21.2%); P = 0.010, respectively. Age at diagnosis increased over time periods, possibly reflecting increased detection of acromegaly in older patients with milder disease. Male gender, older age, smaller tumor and lower IGF-1 index at diagnosis predicted long-term sustained IGF-1 control after surgery without adjuvant therapies. CONCLUSION The vast majority of patients with acromegaly can be biochemically controlled with multimodality therapy in the current era. Radiotherapy and repeat pituitary surgery became less frequently utilized over time. Long-term postoperative IGF-1 control without use of adjuvant therapies has improved.

Abstract
PURPOSE To evaluate the impact of gender and year at surgery on clinical presentation and postoperative outcomes in acromegaly. METHODS Retrospective review of patients operated between 1994 and 2016 to compare presentation and outcomes in groups defined by gender and year of surgery. Kaplan-Meier survival analyses with a composite endpoint (recurrence, reoperation, and radiation) were used for gender comparison and Youden indices for biochemical remission rates changes during study period. RESULTS Primary indications for evaluation were phenotype, neurological symptoms, incidentaloma, hypogonadism, and galactorrhea. At surgery, men (N = 54) were younger (43.6 ± 12.7 years) than women (N = 58, 48.7 ± 12.3, P = 0.04). Male:female ratios before and after age 50 were 1.4 and 0.6 respectively. Men had higher mean IGF-1 levels (874 ± 328 vs 716 ± 296, P < 0.01) and smaller tumors (1.8 ± 1.3 cm vs 2.3 ± 1.5, P = 0.04). Postoperative remission rates were comparable (51% men, 56% women) and inversely associated with cavernous sinus invasion and GH levels. Women had longer mean follow-up (5.2 ± 3.4 years vs 3.6 ± 3.6 men, P = 0.02) and longer endpoint-free survival (P < 0.01). At last follow-up, 89.6% women and 70% men had normal IGF-1 levels (P = 0.03). Postoperative remission rates were higher in patients operated after February 15, 2011 (67.35 vs 43.5% previously, P = 0.01). In late vs early surgery group, physical changes as main indication for screening decreased (54 vs 30%, P < 0.01), while incidentaloma and hypogonadism increased. Median GH levels were lower in late vs early surgery group (P = 0.03). CONCLUSION We demonstrate gender-specific characteristics and an evolving spectrum of clinical presentation with implications for earlier diagnosis and personalized management of acromegaly.

Abstract
The concept of aggressive pituitary tumor (APT) has been precisely defined in recent years. These tumors are characterized by morphological (radiological or histopathological) data of invasion, proliferative activity superior to that of typical adenomas and a clinical behavior characterized by resistance to standard therapies and frequent recurrences. The absence of cerebrospinal or distant metastases differentiates them from the pituitary carcinoma. APTs account for about 10% of all pituitary neoplasm. Proper diagnostic implies participation not only of radiological and hormonal investigation but also a thorough pathological assessment including proliferation markers and immunohistochemistry for hormones and transcription factors. Surgical resection, aiming gross total resection or tumor debulking, is the mainstay initial therapy in most patients. Most patients with APTs need more than one surgical intervention, pituitary radiation, sometimes on more than one occasion, and multiple sequential or combined medical treatments, to finally be doomed to unusual treatments, such as alkylating agents (temozolomide alone or in combination), molecular targeted therapies, or peptide receptor radionuclide therapy. Multimodal therapy, implemented by experts, preferably in specialized centers with high volume caseload, is the only way to improve the prognosis of patients with these uncommon tumors. The research needs in this area are multiple and include a greater knowledge of the molecular biology of these tumors, establishment of protocols for monitoring and sequencing of treatments, development of multicenter studies and international registries.

Abstract
Acromegaly is an insidious disease, usually resulting from growth hormone hypersecretion by a pituitary adenoma. It is most often diagnosed during the 3rd to 4th decade of life. However, recent studies have shown an increase in the incidence and prevalence of acromegaly in the elderly, probably due to increasing life expectancy. As in the younger population with acromegaly, there is a delay in diagnosis, aggravated by the similarities of the aging process with some of the characteristics of the disease. As can be expected elderly patients with acromegaly have a higher prevalence of comorbidities than younger ones. The diagnostic criteria are the same as for younger patients. Surgical treatment of the pituitary adenoma is the primary therapy of choice unless contraindicated. Somatostatin receptor ligands are generally effective as both primary and postoperative treatment. The prognosis correlates inversely with the patient's age, disease duration and last GH level. Arch Endocrinol Metab. 2019;63(6):638-45.

Central Hypothyroidism Related to Pituitary Adenomas: Low Incidence of Central Hypothyroidism in Patients With Acromegaly. J Clin Endocrinol Metab 2019; 104:4879-4888. [PMID: 31188431 DOI: 10.1210/jc.2019-00466] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2019] [Accepted: 06/06/2019] [Indexed: 12/15/2022]
Abstract
CONTEXT The most frequent cause of central hypothyroidism (CeH) is pituitary adenomas, but the mechanisms remain unclear. OBJECTIVE We investigated serum thyroid levels and GH/IGF-1 in central hypothyroidism in untreated patients with pituitary nonfunctioning and GH-secreting adenomas. DESIGN This was a retrospective cross-sectional study of cases collected from Gunma University and Toranomon Hospitals between 2007 and 2016. PATIENTS One-hundred thirty-nine cases of nonfunctioning pituitary adenoma (NFPA) and 150 cases of GH-secreting pituitary adenoma (GHPA) were analyzed. MAIN OUTCOME MEASURES The correlations between thyroid levels, several clinicopathological parameters, and GH/IGF-1 were examined. RESULTS Twenty-four percent of NFPA patients had CeH. The severity did not correlate with tumor size, age, or sex, and all cases had normal TSH levels. In contrast, only 8.7% of GHPA patients had CeH; approximately half had normal TSH levels and approximately half had low TSH levels. Serum TSH levels in GHPA patients were significantly lower and free T4 (FT4) and free T3 levels were higher than those in patients with NFPA. Furthermore, approximately one-fourth of GHPA patients had normal FT4 and low TSH levels. In addition, serum FT4 levels and serum TSH levels were positively and negatively correlated, respectively, with serum IGF-1 levels. Furthermore, IGF-1 levels in patients with GHPA decreased with age. CONCLUSIONS (i) NFPA patients with CeH had TSH levels within a normal range. (ii) GHPA patients had a low incidence of CeH, which may be a result of stimulated thyroid function by GH/IGF-1. (iii) We found an age-dependent decrease in serum IGF-1 levels in patients with GHPA.

Abstract
CONTEXT Sex and age are factors conferring resistance to medical treatment in patients with acromegaly. However, their impact on outcomes of transsphenoidal-selective adenomectomy (TSA) has not been evaluated. OBJECTIVE To analyze age- and sex-related differences concerning surgical outcomes of growth hormone (GH)-secreting pituitary adenomas. DESIGN Retrospective. SETTING Single-center tertiary hospital. PARTICIPANTS Patients with acromegaly (n = 463) who underwent TSA between January 2000 and July 2014. INTERVENTION TSA. MAIN OUTCOME MEASUREMENTS Tumor characteristics and surgical outcomes. RESULTS Sex differences existed in the baseline insulinlike growth factor-1 levels and the mean tumor size. Overall, surgical remission rates were 89.7% and 76.5% in male and female patients, respectively (P < 0.001). Total tumor tissue resection was performed in 92.6% and 85.8% of male and female participants, respectively (P = 0.021). Premenopausal women had a higher proportion of pituitary adenoma with cavernous sinus invasion than did men aged <50 years (35.3% vs 21.7%, P = 0.007). In immediate postoperative, 75-g oral glucose tolerance tests, fewer premenopausal women reached <1 ng/dL nadir GH levels than did men aged <50 years (59.9% vs 87.7%, P < 0.001). Surgical results were similar in both sexes among older patients (≥50 years). However, premenopausal women had significantly lower long-term remission rates than did men aged <50 years (69.3% vs 88.0%, P < 0.001). CONCLUSION Premenopausal women with acromegaly tend to have larger tumors, more aggressive tumor types, and lower remission rates than do men. However, further studies on the clinical implications are needed.

Abstract
Acromegaly is a rare disorder caused by chronic growth hormone (GH) hypersecretion. While diagnostic and therapeutic methods have advanced, little information exists on trends in acromegaly characteristics over time. The Liège Acromegaly Survey (LAS) Database, a relational database, is designed to assess the profile of acromegaly patients at diagnosis and during long-term follow-up at multiple treatment centers. The following results were obtained at diagnosis. The study population consisted of 3173 acromegaly patients from ten countries; 54.5% were female. Males were significantly younger at diagnosis than females (43.5 vs 46.4 years; P < 0.001). The median delay from first symptoms to diagnosis was 2 years longer in females (P = 0.015). Ages at diagnosis and first symptoms increased significantly over time (P < 0.001). Tumors were larger in males than females (P < 0.001); tumor size and invasion were inversely related to patient age (P < 0.001). Random GH at diagnosis correlated with nadir GH levels during OGTT (P < 0.001). GH was inversely related to age in both sexes (P < 0.001). Diabetes mellitus was present in 27.5%, hypertension in 28.8%, sleep apnea syndrome in 25.5% and cardiac hypertrophy in 15.5%. Serious cardiovascular outcomes like stroke, heart failure and myocardial infarction were present in <5% at diagnosis. Erythrocyte levels were increased and correlated with IGF-1 values. Thyroid nodules were frequent (34.0%); 820 patients had colonoscopy at diagnosis and 13% had polyps. Osteoporosis was present at diagnosis in 12.3% and 0.6-4.4% had experienced a fracture. In conclusion, this study of >3100 patients is the largest international acromegaly database and shows clinically relevant trends in the characteristics of acromegaly at diagnosis.

Abstract
DESIGN Valid data on acromegaly incidence, complications and mortality are scarce. The Danish Health Care System enables nationwide studies with complete follow-up and linkage among health-related databases to assess acromegaly incidence, prevalence, complications and mortality in a population-based cohort study. METHOD All incident cases of acromegaly in Denmark (1991-2010) were identified from health registries and validated by chart review. We estimated the annual incidence rate of acromegaly per 10(6) person-years (py) with 95% confidence intervals (95% CIs). For every patient, 10 persons were sampled from the general population as a comparison cohort. Cox regression and hazard ratios (HRs) with 95% confidence intervals (95% CIs) were used. RESULTS Mean age at diagnosis (48.7 years (CI: 95%: 47.2-50.1)) and annual incidence rate (3.8 cases/10(6) persons (95% CI: 3.6-4.1)) among the 405 cases remained stable. The prevalence in 2010 was 85 cases/10(6) persons. The patients were at increased risk of diabetes mellitus (HR: 4.0 (95% CI: 2.7-5.8)), heart failure (HR: 2.5 (95% CI: 1.4-4.5)), venous thromboembolism (HR: 2.3 (95% CI: 1.1-5.0)), sleep apnoea (HR: 11.7 (95% CI: 7.0-19.4)) and arthropathy (HR: 2.1 (95% CI: 1.6-2.6)). The complication risk was also increased before the diagnosis of acromegaly. Overall mortality risk was elevated (HR: 1.3 (95% CI: 1.0-1.7)) but uninfluenced by treatment modality. CONCLUSION (i) The incidence rate and age at diagnosis of acromegaly have been stable over decades, and the prevalence is higher than previously reported. (ii) The risk of complications is very high even before the diagnosis. (iii) Mortality risk remains elevated but uninfluenced by mode of treatment.

Abstract
Acromegaly is a chronic disorder characterized by increased morbidity and mortality in uncontrolled patients. Growth hormone-secreting pituitary adenoma is the hallmark in the majority of cases, generally considered as benign due to lack of distant metastases. However, clinical behavior in a certain proportion of these adenomas could be quite aggressive, causing difficulties in their management. Aggressive pituitary adenomas have some clinical, radiological, ultrastructural and molecular features in common and they are usually resistant to the standard treatment. In the recent years, efforts have been made to define the most appropriate markers of such adenomas that would allow an early detection and efficient individualized therapeutic strategy. The aim of this review is to give an update on epidemiology and certain markers predicting aggressive behavior of somatotropinomas.

World Neurosurg 2016; 88:270-276. [PMID: 26806060 DOI: 10.1016/j.wneu.2015.12.092] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2015] [Revised: 12/25/2015] [Accepted: 12/26/2015] [Indexed: 11/16/2022]
Abstract
BACKGROUND Acromegaly is a multisystemic disease that requires a multidisciplinary approach. The aim of this study was to determine early and late remissions of patients who underwent surgery at our center and to evaluate relations between pathologic and radiologic properties of adenoma and medical and radiosurgical treatments with remissions. METHODS The medical records of 103 patients with acromegaly who underwent endoscopic endonasal transsphenoidal surgery in Cerrahpasa Medical Faculty, Istanbul University, between 2007 and 2014 were reviewed. Clinical, biochemical, radiologic, and pathologic properties were determined. RESULTS The total median follow-up time was 38 months [interquartile range: 24-53.5 months]. Thirty-two percent of the adenomas were microadenomas and 68% were macroadenomas The early remission rate was 51.5% and late remission was 75.2%. The sellar floor invasion was significantly lower in patients with early and late remissions (P = 0.01 and P = 0.009, respectively). The initial growth hormone (GH; P < 0.001), first-day GH (P = 0.03), 3-month GH (P = 0.001), insulin-like growth factor-1 (P = 0.004), and 6-month insulin-like growth factor-1 (P = 0.02) levels were significantly greater in patients with sellar floor invasion. The late remission rates (P = 0.004) were greter and reoperation needs (P = 0.05) were lower in patients with Ki-67 <3% than in patients with ≥3%. Seventy (68.6%) patients needed medical therapy during follow-up. CONCLUSIONS Late remission was achieved using a multidiciplinary approach in 75.2% of 103 patients with acromegaly, and young age, male sex, high Ki-67 and mitosis indices, and cavernous sinus and sellar-floor invasion had negative effects on clinical and biochemical control of the disease.

The Metabolic Risk in Patients Newly Diagnosed with Acromegaly Is Related to Fat Distribution and Circulating Adipokines and Improves after Treatment. Neuroendocrinology 2016; 103:197-206. [PMID: 25592241 DOI: 10.1159/000371818] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2014] [Accepted: 12/31/2014] [Indexed: 11/19/2022]
Abstract
BACKGROUND/AIMS Adipose tissue (AT) distribution is closely related to metabolic disease risk. Growth hormone (GH) reduces visceral and total body fat mass and induces whole-body insulin resistance. Our aim was to assess the effects of total and visceral AT (VAT) distribution and derived adipokines on systemic insulin resistance and lipid metabolism in acromegaly. METHODS Seventy adult patients with active acromegaly (43 males, age 49 ± 14 years) were evaluated before treatment, and a subset (n = 30, 20 males) was evaluated after treatment for acromegaly. Body composition and VAT, glucose metabolism parameters, lipids, C-reactive protein, and selected adipokines (vaspin, omentin, adiponectin, and leptin) were measured. RESULTS At baseline, VAT was positively associated with glucose metabolism parameters and with lipids. GH, but not IGF-I, was negatively associated with all AT depots (visceral, trunk, limbs, and total; 0.41 ≤ r ≤ 0.61, p < 0.001 for all) and positively associated with vaspin (r = 0.31, p = 0.013). The fat deposition after treatment was predominantly located on trunk and visceral depots. The lipid profile partially improved, with increases in HDL and apolipoprotein A-I and a decrease in lipoprotein(a). Vaspin decreased and omentin increased. Adiponectin and leptin did not change significantly. The improvement in homeostasis model assessment for insulin resistance (HOMA-IR) was best predicted by the decreases in IGF-I and vaspin and the lack of an increase in trunk fat (R2 = 0.59, p = 0.001). CONCLUSIONS (1) VAT is a metabolic risk factor for patients with active acromegaly; (2) vaspin and omentin levels are influenced by the disease activity but are not associated with VAT mass; (3) fat deposition after treatment occurs predominantly on the trunk and in visceral depots, and (4) insulin resistance decreases and the lipid profile partially improves with treatment.

Abstract
Certain clinical conditions and markers have recently been demonstrated to modify the natural history of acromegaly in affected patients. Thus, some clinical, histological, radiological and molecular factors are associated with more aggressive pituitary tumors that have higher biochemical activity, higher tumor volumes and decreased tumoral and biochemical responses to current therapies. However, these factors do not seem to have an equal influence on the prognosis of patients with acromegaly. We present a review of the factors that influence the clinical course of patients with acromegaly and propose a risk value for each factor that will allow prognostic scoring for affected patients by considering a combination of these factors.

Abstract
The aim of the present study was to investigate the effect of anti-estrogen treatment (fulvestrant) on the biological activity of hepatocellular carcinoma (HCC), involving the estrogen receptor α (ERα) and Wnt pathways, and to evaluate whether ERα and Wnt inhibitory factor-1 (WIF1) could be biomarkers for anti-estrogen clinical therapy. H22 and HepG2 cells were treated with 0.04 to 625 nM fulvestrant and the WST-8 method was used to assess the inhibition rate after 72 h. Furthermore, prolactin (PRL) secretion by HepG2 cells was assessed at 24 h using an enzyme immunoassay. Quantitative polymerase chain reaction and western blot analysis were used to analyze the mRNA and protein expression levels of ERα, β-catenin and WIF1, respectively, in HepG2 cells. For clinical patient analysis, the tumor volume was analyzed by magnetic resonance imaging methods, and PRL in the blood was detected by an enzyme immunoassay. In HepG2 cells, the mRNA and protein expression levels of ERα were downregulated (P<0.01), while β-catenin expression remained unchanged and WIF1 expression was upregulated (P<0.01). Analysis of samples from clinical patients demonstrated that there was a positive correlation between PRL levels and tumor volume. In addition, as compared with non-cancerous tissues, the ERα mRNA levels in tumor tissue were upregulated (P<0.05), particularly in that of male patients, while WIF1 expression was significantly downregulated (P<0.01). In conclusion, fulvestrant inhibited the proliferation of HepG2 cells, involving the ERα and non-canonical Wnt pathways, and it may be a promising therapeutic for HCC.

Abstract
In March 2011, the Acromegaly Consensus Group met to revise and update the guidelines on the diagnosis and treatment of acromegaly complications. The meeting was sponsored by the Pituitary Society and the European Neuroendocrinology Association and included experts skilled in the management of acromegaly. Complications considered included cardiovascular, endocrine and metabolic, sleep apnea, bone diseases, and mortality. Outcomes in selected, related clinical conditions were also considered, and included pregnancy, familial acromegaly and invasive macroadenomas. The need for a new disease staging model was considered, and design of such a tool was proposed.

Abstract
Acromegaly is a chronic rare disease associated with negative pathological effects on multiple systems and organs. We designed a new informatics tool to study data from patients with acromegaly, the Liege Acromegaly Survey (LAS). This relational database permits the inclusion of anonymous historical and prospective data on patients and includes pathophysiology, clinical features, responses to therapy and long term outcomes of acromegaly. We deployed the LAS in a validation study at a single center in order to study the characteristics of patients with acromegaly diagnosed at our center from 1970-2011. A total of 290 patients with acromegaly were included (147 males and 143 females). There was a linear relationship between age at diagnosis and the date of diagnosis, indicating that older patients are being diagnosed with acromegaly more frequently. A majority presented with macroadenomas (77.5%) and the median diameter was 14 mm. Patients with macroadenomas were significantly younger than patients with microadenomas (P=0.01). GH values at diagnosis decreased with the age of the patients (P=0.01) and there was a correlation between GH values and tumor size at diagnosis (P=0.02). No correlation existed between insulin-like growth factor 1 (IGF-1) levels and tumor characteristics. The prevalence of diabetes was 21.4% in this population and 41.0% had hypertension. The presence of hypertension and diabetes were significantly associated with one another (P<0.001). There was a linear relation between initial GH and IGF-1 levels at diagnosis and those obtained during SSA analog treatment and the lowest GH and IGF-1 values following SSA therapy were obtained in older patients (GH: P<0.001; IGF-1: P<0.001). The LAS is a new relational database that is feasible to use in the clinical research setting and permits ready pooling of anonymous patient data from multiple study sites to undertake robust statistical analyses of clinical and therapeutic characteristics.

Abstract
Somatostatin analogs (SA) are widely used in acromegaly, either as first-line or adjuvant treatment after surgery. First-line treatment with these drugs is generally used in the patients with macroadenomas or in those with clinical conditions so severe as to prevent unsafe reactions during anesthesia. Generally, the response to SA takes into account both control of GH and IGF-I excess, with consequent improvement of clinical symptoms directly related to GH and IGF-I excess, and tumor shrinkage. This latter effect is more prominent in the patients treated first-line and bearing large macroadenomas, but it is also observed in patients with microadenomas, even with little clinical implication. Predictors of response are patients' gender, age, initial GH and IGF-I levels, and tumor mass, as well as adequate expression of somatostatin receptor types 2 and 5, those with the highest affinity for octreotide and lanreotide. Only sporadic cases of somatostatin receptor gene mutation or impaired signaling pathways have been described in GH-secreting tumors so far. The response to SA also depends on treatment duration and dosage of the drug used, so that a definition of resistance based on short-term treatments using low doses of long-acting SA is limited. Current data suggest that response to these drugs is better analyzed taking together biochemical and tumoral effects because only the absence of both responses might be considered as a poor response or resistance. This latter evidence seems to occur in 25% of treated patients after 12 months of currently available long-acting SA.

Abstract
BACKGROUND Somatostatin analogues are the cornerstone in therapy of acromegaly and functioning neuroendocrine tumors. Long-acting retard formulations have improved patient survival and contributed considerably to quality of life. The first such compound was octreotide LAR ('long-acting release'), characterized by high affinity to somatostatin receptor subtypes 2 and 5, which has to be injected intramuscularly every 4 weeks. OBJECTIVE The aim was to screen all octreotide LAR-related literature and assess the compound's profile for safety and tolerability. METHODS An extensive literature search has been performed using the MEDLINE database to retrieve data from clinical studies evaluating the efficacy and tolerability of octreotide LAR. RESULTS/CONCLUSION Octreotide LAR is well tolerated; however, diarrhea and gallstone formation were identified as the main adverse events. Impairment of glucose homeostasis was a regular phenomenon, but its occurrence was unpredictable. General side effects such as headache, abdominal discomfort or fatigue were also reported. According to incidental case reports, administration during pregnancy appears to be safe for both mother and child; however, definitive evidence is missing. In addition, octreotide LAR has been evaluated for further indications including treatment of solid tumor entities, due to its antiproliferative effect. Currently, several compounds (lanreotide, SOM230) with a broader receptor spectrum are under evaluation and may improve treatment efficacy and lower incidence of side effects.

Abstract
OBJECTIVE We evaluated the German Acromegaly Register for clinical variables associated with the initial biochemical activity of patients with acromegaly. DESIGN Retrospective analysis of data in the registry. PATIENTS A total of 1485 patients with acromegaly (males 45.6%, females 54.4%) were treated in 42 German endocrine centres until November 2005. Linear regression models were used to estimate the influence of various parameters on biochemical activity. RESULTS Male patients with acromegaly were significantly younger at the time of diagnosis than female patients (41 vs. 47 years, P < 0.0001) and had significantly higher random GH levels than females (21 vs. 14 ng/ml, P < 0.005) and IGF-1 levels (773 vs. 679 ng/ml, P < 0.0001), respectively. Age at initial presentation turned out to be the most important independent risk factor associated with random GH levels, oral glucose tolerance test-suppressed GH levels, IGF-1 levels, body mass index (BMI), tumour size and prevalence of hypopituitarism. Sex was an independent risk factor for IGF-1 levels, BMI and prevalence of hypopituitarism. Tumour size was an independent risk factor for both GH and IGF-1 levels. CONCLUSIONS In summary, initial biochemical activity of acromegaly is influenced by patient's age and to a lesser degree by patient's sex. Male patients are on an average 6 years younger than females.

Abstract
About one-third of acromegalics are resistant to the clinically available somatostatin analogs (SA). The resistance is related to density reduction or different expression of somatostatin receptor subtypes (SSTR). This study analyzes SSTR's expression in somatotrophinomas, comparing to SA response, hormonal levels, and tumor volume. We analyzed 39 somatotrophinomas; 49% were treated with SA. The most expressed SSTR was SSTR5, SSTR3, SSTR2, SSTR1, and SSTR4, respectively. SSTR1 and SSTR2 had higher expression in patients that had normalized GH and IGF-I. SSTR3 was more expressed in patients with tumor reduction. There was a positive correlation between the percentage of tumor reduction and SSTR1, SSTR2 and SSTR3 expression. Also, a positive correlation between SSTR2 mRNA expression and the immunohistochemical reactivity of SSTR2 was found. Our study confirmed the association between the SA response to GH and IGF-I and the SSTR2. Additionally, this finding was also demonstrated in relation to SSTR1.

Abstract
We assessed the incidence of elderly patients in Japanese acromegalics and the characteristics of their clinical presentation. We also evaluated the safety and efficacy of transsphenoidal surgery (TSS) in this patient group. During the 28-year period from 1980 to 2007 we treated 290 patients with acromegaly at our hospitals. Of these, 9 (3.1%) were elderly, i.e. 70 years old or older. They comprised 0.7% of acromegalics treated during the first- and 4.5% of patients with acromegaly treated during the 2nd 14-year period. Before treatment, all manifested abnormal glucose tolerance; 6 had diabetes mellitus (DM), 6 presented with hypertension, and 2 had cardiovascular disease, malignant neoplasms, or hyperlipidemia. Of the 7 elderly acromegalics who underwent TSS none manifested surgical morbidity or new pituitary hormone deficiencies. Postoperatively, the nadir growth hormone (GH) level at the oral glucose tolerance test (OGTT) was under 1.0 ng/mL in 5 patients, insulin-like growth factor (IGF-1) levels normalized in 4. Glucose tolerance improved in all operated patients. Only 1 of 6 patients with preoperatively diagnosed DM continued to manifest DM post-treatment, anti-hypertensive drugs could be tapered in 3 of patients with preoperative hypertension. In conclusion, we found that there was a high incidence of abnormal glucose tolerance and hypertension in elderly acromegalics, that surgical treatment was effective and safe in this population, and that it was useful for the control of co-morbidities.

Clinical analysis of 103 elderly patients with pituitary adenomas: transsphenoidal surgery and follow-up. J Clin Neurosci 2008; 15:1091-5.

Abstract
Our objective was to study the single-center clinical diagnosis and surgical treatment of pituitary adenomas in elderly patients. A retrospective single-center study was performed on 103 patients aged 65 years and over with a diagnosis of pituitary adenoma and with a mean follow-up duration of 6.1+/-1.3 years. All cases were macroadenomas. The clinical course was dominated by visual disturbance and headache, and hypopituitarism was also not uncommon. Despite the majority of patients (81.6%) having coexisting medical conditions, transsphenoidal surgery (TSS) was performed and well tolerated in all patients. Before 2000, conventional post operative radiotherapy was performed in 32 patients with radiological evidence of tumor remnants. Long-term follow-up revealed no tumor regrowth. However, progressive hypopituitarism was found in a number of patients. After 2000, gamma knife surgery was used for selected cases with documented tumor regrowth. All the remnant tumors treated using this approach appeared to either stabilize or regress without side-effects during the study period. The findings of this analysis support the use of TSS as a feasible treatment for pituitary adenomas in elderly patients. Age alone is no longer considered a contra-indication for treatment with TSS. With appropriate perioperative management, the technique is associated with minimal morbidity and is tolerated well by patients regardless of age. Additional follow-up, especially neuroradiological follow-up is needed to monitor tumor recurrence. However, the indications for post operative radiotherapy should be better defined.

Abstract
Somatostatin receptors are present on most hormone-secreting tumours. They are the pathophysiological basis for the successful control of hormonal hypersecretion by pituitary adenomas, metastatic islet cell tumours and carcinoids during treatment with the long-acting somatostatin analogue octreotide. There is also evidence for inhibition of tumour growth in some of these patients. Visualization of somatostatin receptor-positive tumours is possible in vivo after the administration of ([111In]diethylenetriaminepentaacetic acid)octreotide. Primary tumours are detected and often metastases that were previously unrecognized. Tumours that secrete growth hormone or thyroid-stimulating hormone and non-functioning pituitary adenomas, islet cell tumours, carcinoids, paragangliomas, phaeochromocytomas, medullary thyroid carcinomas and small-cell lung cancers are visualized in 70-100% of cases. Meningiomas, renal cell cancers, breast cancers and malignant lymphomas are often somatostatin receptor positive, allowing their localization with this scanning procedure. In some of these tumours discrepancies have been noted between binding studies with somatostatin-14, somatostatin-28 and octreotide, which suggests the presence of somatostatin receptor subtypes on some tumours. Most hormone-secreting tumours react in vitro to octreotide with an inhibition of hormone release and growth. Cultured meningioma cells react to octreotide with a stimulation in growth, possibly by interference with the autocrine inhibitory growth control by interleukin 6. This suggests that the presence of somatostatin receptors on human tumours does not automatically imply a beneficial effect of somatostatin analogue therapy.

Abstract
This analytical, observational, retrospective, case-control study was designed to describe clinical presentation, biochemical disease severity, presence, and severity of metabolic and cardiovascular complications in patients diagnosed as having acromegaly at 60 yr or older (no.=57) as compared to sex- and age-matched healthy controls. Patients and controls underwent a complete endocrine, metabolic, and cardiovascular check-up. The age at diagnosis was equally distributed between 60 to 75 yr while only a minority of the patients (5.3%) was diagnosed after 75 yr. Median GH and IGF-I levels were 15 microg/l and 557 microg/l. The prevalence of microadenomas, enclosed macroadenomas, and extrasellar/invasive macroadenomas was 30%, 49%, and 21%, respectively. All patients had joint complaints and goiter (euthyroid in 65% and pre-toxic/toxic in 35%), 82% had hypertension, 58% diabetes and 54% had both. As compared to controls, a higher number of patients were receiving treatment with anti-arrhythmiacs (p=0.033), anti-aggregants (p=0.013), levothyroxine (p=0.015), and metformin (p=0.022). Nevertheless, the patients had higher systolic and diastolic blood pressure, heart rate, left ventricular mass index, lipids, glucose and insulin levels as well as percent function of beta cells than controls. In conclusion, the high prevalence of systemic complications makes elderly acromegalics more susceptible than controls to cardiovascular events. We suggest that an accurate clinical check-up and, possibly, a more aggressive treatment of hypertension and diabetes are required in elderly acromegalics.

Abstract
Octreotide has dramatically changed the results of medical treatment of acromegaly. It is the reference drug for the pharmacological treatment of acromegaly, owing to its impressive efficacy in suppressing growth hormome secretion, and excellent compliance. Safe growth hormone and normal insulin-like growth factor I values are reached in 50-60% of unselected patients. Octreotide arrests the growth of the tumor and shrinks tumor in over half of all patients (namely, up to 88% of naive patients and to complete disappearance in anecdotic cases). The safety profile of octreotide is excellent, but in some patients, glucose metabolism worsens and cholelythiasis occurs. This review will address the primary treatment and the relative roles of pharmacological and surgical treatment, as well as the predictivity of octreotide results.

Abstract
BACKGROUND This analytical, retrospective study was designed to select cut-off thresholds of mean GH levels during a diurnal profile and nadir GH levels after oral glucose tolerance test (OGTT) according to age to diagnose surgical remission of acromegaly. METHODS One hundred forty-one patients (76 women, aged 44 +/- 15 years and 65 men, aged 43 +/- 13 years) were included in this study. For the purpose of this study, remission was based on insulin-like growth factor-I (IGF-I) levels in the normal range for age. Diagnostic accuracy was analysed by receiving-operator characteristics (ROC) curves in the entire series, and in young (20-40 years), middle-aged (41-60 years) and older patients (> 60 years), separately. RESULTS Sixty patients (42.6%) had normal IGF-I levels after surgery. In the entire series, in young and in middle-aged patients, the ROC analysis showed that optimum cut-off for mean GH levels was 2.3 microg/l (diagnostic accuracy range, 94-97%) whereas that for nadir GH after OGTT were, respectively, 0.85, 0.9 and 0.8 microg/l (diagnostic accuracy range, 90-95%). In the older patients, the optimum cut-off selected for mean GH levels was 1.4 microg/l and that for nadir GH after OGTT was 0.5 microg/l (diagnostic accuracy, 100% for both). The comparative analysis of the ROC curves did not show any significant difference between mean GH and nadir GH after OGTT (P = 0.21). CONCLUSIONS The criteria currently accepted for diagnosing post-surgical remission of acromegaly have high diagnostic accuracy only in the patients aged below 60 years. In older patients, lower cut-offs (i.e. = 1.4 microg/l for fasting GH and = 0.5 microg/l for nadir GH after OGTT) predict normal IGF-I levels. Mean GH levels during a diurnal profile have similar diagnostic accuracy of nadir GH levels after OGTT. This suggests that OGTT is not necessary to establish surgical cure.

Abstract
Acromegaly is associated with increased morbidity and mortality. Cardiovascular complications are the major predictors of mortality. Age and duration of symptoms are the major determinants of acromegalic cardiopathy. Successful control of acromegaly reverse cardiovascular abnormalities. Herein, we review clinical, biological and histopathological findings in elderly people. Treatments and side effects in relation with aging are questioned.

Abstract
BACKGROUND Multimodal therapy for acromegaly affords adequate disease control for many patients; however, there remains a subset of individuals that exhibit treatment-resistant disease. The issue of treatment-resistant pituitary tumor growth remains relatively under-explored. METHODS We assessed the literature for relevant data regarding the surgical, medical and radiotherapeutic treatment of acromegaly in order to identify the factors that were predictive of aggressive or treatment-resistant pituitary tumor behavior in acromegaly and undertook an assessment of the rates of failure to control tumor progression with available treatment modalities. RESULTS Young age at diagnosis, large tumor size, high growth hormone secretion and certain histological markers are predictors of future aggressive tumor behavior in acromegaly. Significant tumor regrowth occurs in less than 10% of cases thought to be cured surgically, whereas failure to control tumor growth is seen in less than 1% of patients receiving radiotherapy. Somatostatin analogs induce a variable degree of tumor shrinkage in acromegaly but up to 2.2% of somatostatin analog-treated tumors continue to grow. Relative to other therapies, limited data are available for pegvisomant, but these indicate that persistent tumor growth occurs in 1.6-2.9% of cases followed up regularly with serial magnetic resonance imaging scans. CONCLUSIONS Treatment-resistant tumor progression occurs in a small minority of patients with acromegaly, regardless of treatment modality. Young patients with large tumors or those with high pre-treatment levels of growth hormone particularly warrant close monitoring for continued tumor progression during treatment for acromegaly.

Abstract
Os análogos da somatostatina são muito utilizados no tratamento da acromegalia. Com o objetivo de determinar o valor do teste agudo (TA) com octreotide subcutâneo (SC) como preditor da resposta ao tratamento com octreotide LAR®, analisamos os dados de 20 pacientes. Para o TA, amostras de sangue foram colhidas antes e duas horas após a administração de octreotide SC para a dosagem de GH. Os níveis de GH antes e após o TA foram 21,9 (2,3-143,4) e 3,1ng/mL (0,3-61,3), respectivamente. Foi considerado controle de doença: GH< 2,5ng/mL e IGF-I normal em algum momento durante o tratamento. A sensibilidade, especificidade e os valores preditivos positivo e negativo do TA foram 0,9, 0,6, 0,69 e 0,86 para redução de 75% do GH no teste. Concluímos que, em nossa casuística, um decréscimo de 75% dos níveis de GH no TA teve um bom poder discriminatório entre pacientes com maior e menor chance de resposta ao tratamento.

Abstract
Lanreotide (LAN) 60 mg (LAN60), a new long-acting formulation of LAN alleged to suppress GH/IGF-I hypersecretion for 28 d in acromegalic patients, was administered in a prospective open multicenter study to 92 patients with active acromegaly (61 women and 31 men, aged 20-79 yr). LAN60 was given as adjuvant treatment (AT) in 62 patients; the other 30 patients [primary treatment (PT)] were de novo (n = 20) or previously treated only by pharmacotherapy (n = 10). After wash-out from previous treatments, LAN60 was started im every 28 d for 3 injections; the dose was then individually tailored, aiming at lowering GH to less than 2.5 micro g/liter and IGF-I to the normal range. After a median follow-up of 24 months (range, 6-48 months), IGF-I normalized in 65% of patients, decreasing from 199 +/- 8% (expressed as a percentage of the upper limit of normal range; mean +/- SE) to 87 +/- 4% (P < 0.0001). GH fell to less than 2.5 microg/liter in 63% of patients and to less than 1 microg/liter in 25%, decreasing from 20 +/- 3 to 3 +/- 0.4 microg/liter (P < 0.0001). A progressive increase in the rate of IGF-I normalization was observed (from 49% at 1 yr to 77% at 3 yr). The rate of GH/IGF-I normalization was 72% at 36 months by Kaplan-Meier analysis. No tachyphylaxis was observed throughout the study. Shortening the interval between injections to 21 d improved GH/IGF-I suppression. PT and AT patients achieved similar final GH/IGF-I levels and rates of normalization. Tumor shrank in 39% of assessable patients and in 50% of PT. Plasma glucose levels did not change, and high density lipoprotein cholesterol increased (by 19.3 +/- 5.1%; P = 0.0215). Gallstones appeared or worsened in 13% of patients. LAN60 is a new, very effective and long-lasting formulation for the treatment of acromegaly. The persistence of a powerful suppression of GH/IGF-I levels, the progressive increase in the rate of IGF-I normalization, and the similarity in the efficacy achieved in PT and AT patients point to a role for LAN60 in the primary treatment of acromegaly.

Abstract
An oral glucose tolerance test (OGTT) was used to assess growth hormone (GH) secretion in patients with acromegaly prior to (n = 26) and after (n = 71) transsphenoidal adenomectomy as well as in 196 controls. In controls, suppressed concentrations of GH showed a negative relationship both with body mass index (BMI) and with age. Having calculated the reference intervals for suppressed GH concentrations to be expected for any given age and BMI, we compared these individually predicted ranges to GH concentrations actually observed in patients with acromegaly during OGTT. Preoperatively, concentrations exceeded the normal range in all patients. Postoperatively, glucose-suppressed concentrations of GH were less than 2.0 ng/mL in 56 (79%) patients and less than 1.0 ng/mL in 44 (62%). However, only 37 of 71 (52%) patients had glucose-suppressed GH concentrations within the calculated reference intervals (defined by the 95th percentile of normal). Comparing these data with the patient's concentrations of insulin-like growth factor-1 (IGF-1; normal range first established and corrected for age and sex in 494 healthy individuals), congruency of both parameters was found in 59 (77%) patients with an unexplained discrepancy between GH and IGF-1 in the remaining in 16 (23%) patients. Our results confirm that concentrations of IGF-1 must be corrected for sex and age, whereas glucose-suppressed concentrations of GH depend on age and BMI. "Across-the-board" cut-off-values are clearly inadequate and should not be used. Rather, serum GH measurements obtained during an OGTT must be interpreted individually by comparison to control values taking into account both age and BMI.

Abstract
Pituitary adenomas in the elderly represent an increasing proportion of pituitary tumors, making the surgical management of these patients of special importance. We therefore decided to review our experience with transsphenoidal surgery (TSS) in this age group, in order to better evaluate its efficacy, safety and outcome. A retrospective study was performed on 39 patients aged more than 70 years at the time of surgery (mean age 74.1 +/- 2.9 years) and with a minimum follow-up duration of 4 years at the time of the study. Thirty-one had a nonfunctioning pituitary adenoma, 5 had a GH-secreting adenoma and 3 a macroprolactinoma, respectively. The commonest presenting symptom was visual deterioration (60%), whereas hypopituitarism were present in 41% of patients. All patients underwent TSS without any major peri- and post-operative complications. Visual fields improved in 74% of patients. Post-operative radiotherapy was performed in 17 patients with partial surgical resection and/or persistent hormonal hypersecretion, whereas 22 patients with subtotal or total surgical resection were treated by surgery only. Long-term follow-up (mean 9.1 +/- 2.7 years) showed evidence for tumor regrowth in one irradiated (5.9%) and 3 non-irradiated patients (13.6%), respectively. A noticeable complication of radiotherapy was progressive hypopituitarism, which worsened or developed in 65% of patients. We conclude that TSS is safe and well tolerated even in elderly patients, with a low incidence of minor complications. The indications for post-operative radiotherapy in patients with incomplete tumor resection should be better defined.

Abstract
BACKGROUND In patients with acromegaly serum IGF-I is increasingly used as a marker of disease activity. As a result, the relationship between serum GH and IGF-I is of profound interest. Healthy females secrete three times more GH than males but have broadly similar serum IGF-I levels, and women with GH deficiency require 30-50% more exogenous GH to maintain the same serum IGF-I as GH-deficient men. In a selected cohort of patients with active acromegaly, studied off medical therapy using a single fasting serum GH and IGF-I measurement, we have reported previously that, for a given GH level, women have significantly lower circulating IGF-I. OBJECTIVE To evaluate the influence of age and gender on the relationship between serum GH and IGF-I in an unselected cohort of patients with acromegaly independent of disease control and medical therapy. METHODS Sixty (34 male) unselected patients with acromegaly (median age 51 years (range 24-81 years) attending a colonoscopy screening programme were studied. Forty-five had previously received pituitary radiotherapy. Patients had varying degrees of disease control and received medical therapy where appropriate. Mean serum GH was calculated from an eight-point day profile (n = 45) and values obtained during a 75-g oral glucose tolerance test (n = 15). Serum IGF-I, IGFBP-3 and acid-labile subunit were measured and the dependency of these factors on covariates such as log10 mean serum GH, sex, age and prior radiotherapy was assessed using regression techniques. RESULTS The median calculated GH value was 4.7 mU/l (range 1-104). A significant linear association was observed between serum IGF-I and log10 mean serum GH for the cohort (R = 0.5, P < 0.0001). After simultaneous adjustment of the above covariates a significant difference in the relationship between mean serum GH and IGF-I was observed for males and females. On average, women had serum IGF-I levels 11.44 nmol/l lower than men with the same mean serum GH (P = 0.03, 95% CI 1.33-21.4 nmol/l). Age significantly influenced the relationship and for a given serum GH, IGF-I was estimated to fall by 0.37 nmol/l per year (P = 0.04, 95% CI 0.015-0.72). CONCLUSIONS In keeping with previous observations of relative GH resistance in normal and GH-deficient females we have observed lower serum IGF-I levels for equivalent mean serum GH levels in females patients with acromegaly. This gender-dependent difference is independent of disease activity and the use of concomitant medical therapy. Additionally, we have demonstrated that for a given serum GH level, age significantly influences IGF-I concentrations in patients with acromegaly. These data have important implications for the use of serum IGF-I and GH as markers of disease activity in acromegaly.

Abstract
Acromegaly is a severe slow-developing disease associated with a poor prognosis for cardiovascular disease. To evaluate the impact of age and gender on the severity of the disease, 151 de novo patients with acromegaly (79 women, 72 men, age range 19-77 yr) were included in this open retrospective multi-center cohort study. Basal GH and IGF-I levels, GH response after glucose load and maximal tumor diameter at MRI were measured in all patients at diagnosis. Fasting GH levels and maximal tumor diameter were similar in women and men, while serum IGF-I levels were lower (664.9+/-24.9 vs 755.9+/-32 microg/l; p=0.02) and GH nadir after glucose load was higher (27.5+/-3.7 vs 18.5+/-2.2 microg/l; p=0.04) in women than in men. In both sexes, patients' age was negatively correlated with basal and nadir GH, IGF-I levels and tumor size; fasting GH levels were positively correlated with IGF-I levels and nadir GH after glucose. No interaction between age and gender was found on biochemical and morphological parameters. At diagnosis, elderly patients with acromegaly have lower GH and IGF-I levels, lower GH nadir after glucose load and smaller adenomas than young patients. Women have lower IGF-I levels but higher GH nadir after glucose load than men. These age and gender differences should be considered to appropriately evaluate the activity of acromegaly throughout a life-span.

Abstract
OBJECTIVE To investigate the effect of gender on the response of GH to short-acting octreotide in patients with acromegaly, and on the GH and IGF-1 levels during long-term treatment with a slow-release formulation of octreotide. STUDY DESIGN AND PATIENTS Twenty-one men (mean age 54 years; range 26-78) and 15 women (mean age 54 years; range 22-74) with acromegaly were treated with subcutaneous injections of 100 microg short-acting octreotide twice daily. Serum samples for GH were taken before start of treatment, in the morning prior to the injection, and 1, 3, 5 and 7 h after the injection. Thirteen men (mean age 56 years; range 34-78) and 12 women (mean age 64 years; range 28-81) with acromegaly were switched from ongoing treatment with short-acting octreotide to injections of the slow-release formulation. A 4-h GH-profile and morning IGF-1 were taken at start and after 3, 9, 15 and 21 months of treatment. RESULTS Subcutaneous injections of 100 microg octreotide reduced the mean level of GH during a 7-h period to a similar extent in men and women compared to the GH levels prior to the injections. During long-term treatment with similar doses of the depot formulation of octreotide, the mean IGF-1 level remained significantly higher in the men than in the women, whereas there were no differences in the mean GH levels between the two groups. CONCLUSIONS The responses to short- and long-acting octreotide illustrate an effect of gender, due to different sensitivity to GH in the periphery. Furthermore, the results show that in the treatment of acromegaly, men will need higher doses of octreotide than women to normalize IGF-1.

Abstract
The principal biochemical criteria for cure in acromegaly are normalization of both glucose-suppressed GH levels and IGF-I levels. As we have reported previously, measurement of GH by highly sensitive assay in conjunction with IGF-I levels has led to a re-appraisal of "normal" GH suppression criteria during an OGTT in subjects with acromegaly. In some patients with active acromegaly, glucose-suppressed GH levels as measured by highly sensitive assay are much lower than could previously be appreciated with less sensitive GH assays and some other patients in apparent remission have subtle abnormalities of GH suppression. A question to arise is whether gender differences in glucose-suppressed GH levels as found by others in young healthy subjects should be considered in our interpretation of OGTT criteria for cure in acromegaly. Therefore, we have evaluated parameters of GH secretion in a larger number of subjects from our cohort of postoperative patients with acromegaly and in healthy subjects in order to determine if gender or age associated differences in these parameters exist. Ninety-two subjects with acromegaly (49 men, 43 women) and 46 age-matched healthy subjects (26 men, 20 women) were evaluated with baseline GH and IGF-I levels and nadir GH levels after a 100 g. OGTT. GH was assayed by highly sensitive IRMA (DSL). Basal GH levels were higher in female than in male healthy subjects, but the fall in GH from baseline (% suppression) was also greater in females resulting in no significant difference in mean nadir GH levels in female vs. male healthy subjects (0.09 vs. 0.08 microg/L). In the subjects with acromegaly, there were no significant gender differences in basal, %GH suppression or nadir GH levels. Basal and nadir GH levels correlated significantly only in subjects with active disease (r=0.84, p<.0001). Similarly, IGF-I levels correlated significantly with basal (r=0.573, p=.0012), and nadir (r=.702, p<.0001) GH levels only in subjects with active disease. Gender differences in IGF-I levels were not apparent in any group of subjects. As expected, IGF-I levels declined with age in those groups of subjects with normal IGF-I levels. Nadir GH levels did not vary with age. In conclusion, we have not found significant gender or age-related differences in nadir GH levels and thus our data does not support separate OGTT criteria for cure in men and women with acromegaly.

Abstract
New depot somatostatin analogs such as lanreotide-slow release (LAN) represent a significant improvement in the medical treatment of acromegaly. Seventy-three consecutive acromegalic patients, treated by LAN, were evaluated in a retrospective monocentric study. Sixteen were excluded from further evaluation due to combined treatment with dopamine agonist drugs, early LAN withdrawal for persistence of headache, or gastrointestinal side-effects. Fifty-seven patients (aged 20-82 years, 16 males) were thus evaluated. Thirty-two patients had been previously treated by neurosurgery (Tx) and/or radiotherapy (Rx). After washout, LAN (30 mg) was administered im at 10-14-day intervals. Time intervals between injections were then individually tailored to normalize IGF-I levels. LAN was administered for 12 (6-36) [median (range)] months. GH and IGF-I levels decreased from 13 (7-20) [median (interquartile)] microg/l to 3.2 (1.7-6.2) microg/l (p<0.0001) and from 780 (596-1000) microg/l to 264 (180-530) microg/l (p<0.000001), respectively. Seven patients were resistant to treatment. Among the 50 sensitive patients, GH levels fell below 2.5 microg/l in 52% (and below 1 microg/l in 18%), IGF-I levels normalized in 72% and both results were obtained in 46%. IGF-I values normalized in 87% of patients treated every 14 days, in 100% every 21-28 days, in 69% every 10 days and in 22% every 7 days. No different control of GH/IGF-I hypersecretion was evidenced between patients previously treated or not by Tx and/or Rx. Patients with the lowest basal hormonal levels and those over 55 years showed greater responsiveness (both p<0.05). The maintenance of LAN schedule up to 18 months determined a further suppression (p=0.04 for IGF-I). A reduction of tumor size was shown in 60% of evaluated patients (6/10). HbA1c slightly increased in 42% of patients and gallstones were observed in 16%. LAN is a very effective tool in the treatment of acromegaly: its chronic administration normalizes GH/IGF-I levels in most patients, shrinks the tumor in a high percentage of patients and seems to control hormonal hypersecretion as primary treatment as well as neurosurgery.
