PRolaCT - Three Prolactinoma RCTs

2019-10-03 07:54:47 | BioPortfolio

Summary

This study aims to investigate if endoscopic trans-sphenoidal prolactinoma resection as a first line treatment, or as an equally valid second line treatment after a short (4-6 months) or long (>2 years) period of pretreatment with a dopamine agonist is superior to standard care for several outcome parameters. The main objectives are to investigate this for quality of life and remission rate. The secondary objectives are to investigate this for biochemical disease control, recurrence rates, clinical symptom control, tumor shrinkage on MRI, pituitary functioning, the occurrence of adverse reactions to treatment, disease burden, and cost-effectiveness.

Comparison of Short-Term Outcomes Between Endoscopic and Microscopic Trans-Sphenoidal Surgery for the Treatment of Pituitary Adenoma.

Until today, it is unclear if endoscopic or microscopic transsphenoidal surgery is the most adequate treatment technique for pituitary adenoma, while microscopic transsphenoidal surgery is termed as a...

Endoscopic resection of a scarred rectal adenoma using EndoRotor.

 Benign colorectal neoplasia are commonly resected using snare resection or endoscopic submucosal dissection (ESD). These methods are safe, but just the piecemeal resection in flat adenomas greater ...

Excellent response to pasireotide therapy in an aggressive and dopamine-resistant prolactinoma.

Prolactinomas are the most commonly encountered pituitary adenomas in the clinical setting. While most can be controlled by dopamine agonists, a subset of prolactinomas are dopamine-resistant and very...

Excellent response to pasireotide therapy in an aggressive and dopamine-resistant prolactinoma - commentary.

Recent publications suggested that pasireotide could be a good therapeutic option in some dopamine resistant or aggressive prolactinomas. We discussed the 2 published cases and describe another case o...

Prolactinomas and nonfunctioning adenomas: preoperative diagnosis of tumor type using serum prolactin and tumor size.

Prolactinoma and nonfunctioning adenoma (NFA) are the most common sellar pathologies, and both can present with hyperprolactinemia. There are no definitive studies analyzing the relationship between t...

Medical and Biotech [MESH] Definitions

An ergot derivative that acts as an agonist at dopamine D2 receptors (DOPAMINE AGONISTS). It may also act as an antagonist at dopamine D1 receptors, and as an agonist at some serotonin receptors (SEROTONIN AGONISTS).

Drugs that bind to but do not activate DOPAMINE RECEPTORS, thereby blocking the actions of dopamine or exogenous agonists. Many drugs used in the treatment of psychotic disorders (ANTIPSYCHOTIC AGENTS) are dopamine antagonists, although their therapeutic effects may be due to long-term adjustments of the brain rather than to the acute effects of blocking dopamine receptors. Dopamine antagonists have been used for several other clinical purposes including as ANTIEMETICS, in the treatment of Tourette syndrome, and for hiccup. Dopamine receptor blockade is associated with NEUROLEPTIC MALIGNANT SYNDROME.

Drugs that bind to and activate dopamine receptors.

A pituitary adenoma which secretes PROLACTIN, leading to HYPERPROLACTINEMIA. Clinical manifestations include AMENORRHEA; GALACTORRHEA; IMPOTENCE; HEADACHE; visual disturbances; and CEREBROSPINAL FLUID RHINORRHEA.

Total or subtotal destruction of the pituitary gland by chemical injection. It is usually achieved by injection of ethyl alcohol via trans-sphenoidal cannulation under stereotaxic control. It is usually performed for the treatment of intractable pain.
