Abstract
Growth hormone-secreting pituitary adenoma (GHPA) represents about 20% of all histological subtypes of pituitary adenoma (PA), which may result in serious complications and shortened lifespan via growth-hormone (GH) hypersecretion. To date, no biomarkers of early diagnosis or therapeutic targets for GHPA treatment have yet been found. Recently, growing evidence has indicated that circular RNAs (circRNAs) are critical for the development and progression of numerous diseases, including cancers; however, their role in the pathogenesis of GHPA has not been reported. Here, we revealed the expression profile of circRNAs in GHPA using a circRNA microarray, and found 1938 circRNAs were upregulated and 1601 circRNAs were downregulated in GHPA versus normal control. Then the ten most up-regulated circRNAs were selected for the mapping of a circRNA-miRNA-target gene interaction network. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses further indicate that target genes were mostly enriched in the mTOR and the Wnt signaling pathway. Among these differentially expressed circRNAs, hsa_circ_0001368 was verified significant up-regulated by qRT-PCR, which was specific up-regulated in GHPA and correlated with the invasiveness and serum GH level of GHPA; functional studies indicated that knockdown of hsa_circ_0001368 significantly inhibited the proliferation, invasion and GH secreting level of GHPA primary culture cells. Moreover, hsa_circ_0001368 had a significant positive correlation with the pituitary-specific transcription factor Pit-1. In conclusion, our study identified a wealth of candidate circRNAs involved in GHPA and proposed that hsa_circ_0001368 may represent a novel potential biomarker and therapeutic target of GHPA.

Abstract
Invasiveness in pituitary adenomas has been defined and investigated from multiple perspectives, with varying results when its predictive value is considered. A systematic literature review, following PRISMA guidelines, was performed, searching PubMed and Scopus databases with terms that included molecular markers, histological, radiological, anatomical and surgical data on invasiveness of pituitary adenomas. The results showed that differing views are still present for anatomical aspects of the sellar region that are relevant to the concept of invasiveness; radiological and histological diagnoses are still limited, but might improve in the future, especially if they are related to surgical findings, which have become more accurate thanks to the introduction of the endoscope. The aim is to achieve a correct distinction between truly invasive pituitary adenomas from those that, in contrast, present with extension in the parasellar area through natural pathways. At present, diagnosis of invasiveness should be based on a comprehensive analysis of radiological, intra-operative and histological findings.

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
OBJECTIVE AND DESIGN The resistance of macroprolactinomas to dopamine agonist (DA) therapy, whether defined as an absence of PRL normalization or the lack of significant tumour shrinkage after prolonged treatment at high doses, is usually regarded as unpredictable. The aim of this retrospective study, conducted in a teaching hospital, was to determine whether cavernous sinus (CS) invasion assessed by magnetic resonance imaging (MRI) is associated with a higher rate of resistance to DA therapy. METHODS Forty-nine patients with a macroprolactinoma were included in this study and classified into four groups according to the percentage of encasement of the intracavernous internal carotid artery (ICA) by the tumour. All patients received DA as the primary treatment, mainly cabergoline (CAB). PRL normalization and tumour shrinkage during treatment were evaluated as a function of CS invasion. RESULTS Tumours encasing more than three-quarters of the intracavernous ICA (group 4) were less responsive to DA therapy, exhibiting a lower rate of early (< or = 3 months) PRL normalization (8%vs. 69% in the others groups; P < 0.01) under a higher dose of CAB (median: 3.5 mg vs. 1.0 mg per week; P < 0.01). CS invasion was a strongly significant and independent predictor of hormonal resistance to CAB (P < 0.01). This hormonal resistance occurred in eight patients (16%), all but one belonging to group 4. Significant tumour shrinkage was observed in 31 out of 45 assessable cases (69%) and was more likely to occur in the case of PRL normalization (P < 0.01). CONCLUSIONS Parasellar extension of macroprolactinomas, assessed on the basis of strict MRI criteria, may predict a negative response to DA. The responsiveness of noninvasive macroprolactinomas (over 90%) is similar to that reported in microprolactinomas, whereas invasive tumours are resistant to treatment in more than 50% of cases.
