Pattern of Gene Expression in Adipose Tissue From Patients With Cushing Syndrome

Cushing Syndrome Related to Cortisolic Adenoma

The purpose of this trial is to investigate the impact of cortisol on adipose tissue functions, distribution and morphology. Patient with endogenous blood cortisol excess exhibit changes in adipose tissue, with fat gain in the upper trunk, face and neck leading to visceral obesity and features of the metabolic syndrome. The aims of this study will be to compare the pattern of gene expression between visceral and subcutaneous adipose tissue in Cushing patients requiring an adrenalectomy as cortisol adenoma treatment; to compare these patterns of gene expression with those of two control populations:1/ healthy metabolic subjects having a partial nephrectomy, 2/obese patients with similar degree of insulin resistance.

Surgical Debulking of Pituitary Adenomas

Pituitary Adenoma

This is a randomized, multicenter trial with stratification done by a single radiologist at the coordinating center (NYU), and patients with comparable disease will be randomized to Sandostatin LAR treatment administered 1 time per month by IM injection for 3 months before (Arm A) or, for non-cured patients, after (Arm B) surgery. All patients will undergo transsphenoidal hypophysectomy. The impact of surgical debulking on responsiveness to Sandostatin LAR will be evaluated.The primary objective of this trial will be to determine whether surgery (debulking of pituitary adenomas) improves the response of patients with acromegaly to treatment with Octreotide LAR, when compared to Octreotide LAR therapy alone.

De-implementation of Outdated Colonoscopy Surveillance Interval Recommendations Among Patients With...

Polyp of Colon

The purpose of this study is to compare the effectiveness of three standard of care outreach approaches (i.e., mailed letter, secure message, and telephone call) on patient adoption of the new 10-year colonoscopy surveillance interval recommendation for a random sample of health plan members who have a now-outdated 5-year surveillance interval due to a finding of 1-2 small adenomas at their prior colonoscopy. The primary study endpoint is the proportion of patients in each outreach arm who adopt the new 10-year colonoscopy surveillance interval.

Assessment of Cardiovascular Risk Markers in Growth Hormone Deficient Patients With Nonsecreting...

Growth Hormone DeficiencyPituitary Tumor

The purpose of this study is to determine if patients with a history of nonsecreting pituitary adenomas with untreated GH deficient patients have profiles consistent with increased cardiovascular risk compared to patients without GH deficiency who have undergone similar surgery.

Endoscopic Submucosal Dissection Versus Transanal Endoscopic Microsurgery For Early Rectal Neoplasms...

Early Rectal CancerLarge Rectal Adenomas

Transanal endoscopic microsurgery is the main treatment option for rectal tumors such as large adenoma, early cancer because of lower complications and mortality rates and shorter hospital stays rather than conventional surgery. Particularly, However, transanal endoscopic microsurgerymust be performed under either general or spinal anesthesia, and expensive surgical instruments are required. Colorectal endoscopic submucosal dissection is a novel endoscopic procedure that enables en bloc resection of benign colorectal lesions and early colorectal cancer. Endoscopic submucosal dissectioncan be performed under conscious sedation without anesthesia, and there are fewer hospital days than those for transanal endoscopic microsurgery. In the present study, we compared the treatment efficacy and safety between endoscopic submucosal dissectionand transanal endoscopic microsurgery for the treatment of early rectal neoplasms and large rectal adenomas.

Pain Management After Transnasal Transsphenoidal Surgery for Pituitary Adenomas

Pituitary AdenomaSurgery1 more

We hypothesize that the effects of non-steroidal anti-inflammatory drugs (NSAIDS) for pain relief among patients with pituitary adenomas undergoing transnasal transsphenoidal surgeries are non-inferior to tramadol. We aim to launch a single-center randomized clinical trial to verify this hypothesis.

Multicenter Evaluation of the Effect of Upfront Radiosurgery on Residual Growth Hormone-secreting...

Acromegaly Due to Pituitary Adenoma

In this study, the investigators hypothesize that upfront gamma knife radiosurgery with drug therapy is superior in the treatment of growth hormone-secreting pituitary tumors after primary surgical treatment compared with the drug therapy alone. This study can provide useful clinical information in the treatment of patients with acromegaly.

EMR Versus ESD for Resection of Large Distal Non-pedunculated Colorectal Adenomas

Colorectal Neoplasms

Endoscopic resection of adenomas in the colon is the cornerstone of effective colorectal cancer prevention. Endoscopic mucosal resection (EMR) is currently the most used technique for resection of large distal colorectal adenomas, however, maintains some important limitations. In large lesions, EMR can often only be performed in a piecemeal fashion resulting in relatively low R0-resection rates and high recurrence rates. Endoscopic submucosal dissection (ESD) is a newer procedure that is more difficult resulting in a longer procedural time, but is promising due to the high en-bloc resection rates and the very low recurrence rates. The aim of this multicenter randomized study is to compare EMR and ESD with regard to recurrence rates and radical (R0) resection rates, and to put this into perspective against the costs and complication rates of both strategies and the burden perceived by patients on the long term-term.
