Medical therapies in pituitary adenomas: Current rationale for the use and future perspectives

Pituitary adenomas (PA) represent in the majority of cases, benign tumors whose treatment currently associate surgery, medical therapies and radiotherapy in a multidisciplinary approach. While trans-sphenoidal surgery remains, except for prolactin-secreting adenomas, the first-line treatment of PA, it can considerably be hampered by the existence of an invasive and/or aggressive tumor for which medical therapies are often requested. In this review, we extensively discuss, both at molecular and clinical levels, the medical therapies currently used and in development in the different phenotypes of pituitary adenomas.     

Islets and pancreatic ductal adenocarcinoma – An opportunity for translational research from the ‘Bench to the Bedside’

The islet-acinar axis is of prime importance to the optimal functioning of the human pancreas. Not only is this inter-relationship important for normal physiological processes, it is also relevant in diseased states, including chronic pancreatitis and pancreatic ductal adenocarcinoma (PDAC). Early experiments, nearly 4 decades ago, explored the role of islets in the development and progression of PDAC. These led to further studies that provided compelling evidence to support the role of islets and their hormones in PDAC. This association presents oncologists with therapeutic options not only for managing, but potentially preventing PDAC, a cancer that is well known for its poor patient outcomes. This review will discuss the accumulated evidence regarding the role of islets and their hormones in PDAC and highlight areas for future research.     

Outcome of Endoscopic Transsphenoidal Surgery in Combination with Somatostatin Analogues in Patients with Growth Hormone Producing Pituitary Adenoma

Objective

To determine the efficacy of endoscopic surgery in combination with long-acting somatostatin analogues (SSAs) in treating patients with growth hormone (GH)-secreting pituitary tumor.

Methods

We performed retrospective analysis of 133 patients with GH producing pituitary adenoma who underwent pure endoscopic transsphenoidal surgery in our center from January 2007 to July 2012. Patients were followed up for a range of 3-48 months. The radiological remission, biochemical remission and complication were evaluated.

Results

A total of 110 (82.7%) patients achieved radiological complete resection, 11 (8.2%) subtotal resection, and 12 (9.0%) partial resection. Eighty-eight (66.2%) patients showed nadir GH level less than 1 ng/mL after oral glucose administration. No mortality or severe disability was observed during follow up. Preoperative long-acting SSA successfully improved left ventricle ejection fraction (LVEF) and blood glucose in three patients who subsequently underwent success operation. Long-acting SSA (20 mg every 30 days) achieved biochemical remission in 19 out 23 (82.6%) patients who showed persistent high GH level after surgery.

Conclusion

Endoscopic transsphenoidal surgery can biochemically cure the majority of GH producing pituitary adenoma. Post-operative use of SSA can improve biochemical remission.     

GIPR expression in gastric and duodenal neuroendocrine tumors

Background

Compounds targeting somatostatin-receptor-type-2 (SSTR2) are useful for small bowel neuroendocrine tumor (SBNET) and pancreatic neuroendocrine tumor (PNET) imaging and treatment. We recently characterized expression of 13 cell surface receptor genes in SBNETs and PNETs, identifying three drug targets (GIPR, OXTR, and OPRK1). This study set out to characterize expression of this gene panel in the less common neuroendocrine tumors of the stomach and duodenum (gastric and duodenal neuroendocrine tumors [GDNETs]).

Methods

Primary tumors and adjacent normal tissue were collected at surgery, RNA was extracted, and expression of 13 target genes was determined by quantitative polymerase chain reaction. Expression was normalized to GAPDH and POLR2A internal control genes. Expression relative to normal tissue (ddCT) and absolute expression (dCT) were calculated. Wilcoxon tests compared median expression with false discovery rate correction for multiple comparisons.

Results

Gene expression was similar in two gastric and seven duodenal tumors, and these were analyzed together. Like SBNETs (n = 63) and PNETs (n = 51), GDNETs showed significant overexpression compared with normal tissue of BRS3, GIPR, GRM1, GPR113, OPRK1, and SSTR2 (P < 0.05 for all). Of these, SSTR2 had the highest absolute expression in GDNETs (median dCT 4.0). Absolute expression of BRS3, GRM1, GPR113, and OPRK1 was significantly lower than SSTR2 in GDNETs (P < 0.05 for all), whereas expression of GIPR was similar to SSTR2 (median 4.3, P = 0.4).

Conclusions

As in SBNETs and PNETs, GIPR shows absolute expression close to SSTR2 but has greater overexpression relative to normal tissue (21.1 versus 3.5-fold overexpression). We conclude that GIPR could provide an improved signal-to-noise ratio for imaging versus SSTR2 and represents a promising novel therapeutic target in GDNETs.     

Polykystose rénale autosomique dominante : le traitement est-il pour demain ?

Autosomal dominant polycystic kidney disease (ADPKD) is the most frequent Mendelian inherited disorder. It covers 6.1% of incident ESRD patients in France in 2011. Long left untreated, this disease will soon benefit from targeted therapies currently under evaluation. Several molecules have already reached the stage of clinical trials: the evaluation of mTOR inhibitors yielded deceiving results and, more recently, 2 different molecules demonstrated a slight impact on the progression of total kidney volume (TKV): tolvaptan, vasopressin receptor-V2 inhibitor and somatostatin analogues; both of these molecules acting throughout the decrease of intracellular AMPc. The purpose of this review is to briefly describe the signaling pathways involved, then to present both the published and ongoing clinical trials and the promising molecules evaluated in murine models.     

胃肠激素检测在小于胎龄儿变化中临床意义

应用放射免疫法对68例小于胎龄儿(其中早产36例;足月32例)生后喂奶前及第7日空腹血中生长抑素(soma-tostatin,SS)、胃动素(motilin,MOT)、胃泌素(gastrin,Gas)浓度进行测定,并以30例足月新生儿作为对照组。结果小于胎龄儿组生后喂奶前及第7日空腹血浆胃动素、胃泌素均明显低于对照组,而生长抑素浓度明显高于对照组.并且与胎龄、开始喂养时间及当日进奶等因素相关。结论小于胎龄儿消化道机能适应胃肠道营养,在严密观察下应用合理的喂养方式早日开始胃肠道营养,将能促进小于胎龄儿胃肠道的发育和成熟。     

食管癌及胃癌患者血浆和癌中生长抑素含量变化

本文采用放免测定法研究了生长抑素（ｓｏｍａｔｏｓｔａｔｉｎ，ｓｓ）在胃及食管癌患者血浆与癌组织中的变化。结果表明：食管癌和胃癌患者血浆和癌组织中ｓｓ的含量（食管癌：１７．８７±５．３１ｐｇ／ｍｌ，４０．４１±１３．２６ｐｇ／ｍｇ；胃癌：１１．２４±５．１１ｐｇ／ｍｌ，１３０．１８±３７．７３ｐｇ／ｍｇ）显著低于正常人（２６．８３±５．９２，２１２．６２±４７．４６ｐｇ／ｍｇ）Ｐ＜０．０１，提示：ｓｓ的减少可能与上消化道癌肿形成有关。
