Abstract

Prolactinomas are the most common secretory tumor of the pituitary gland. Clinical symptoms may be due to prolactin oversecretion, localized mass effect, or a combination of both. Although the mainstay of prolactinoma management is medical therapy with dopamine agonists, endoscopic endonasal or transcranial surgery, radiation therapy, or a combination of these is an important treatment option in select cases. This article discusses prolactinoma phenotypes, clinical presentations, and clinically pertinent medical and surgical considerations when managing these tumors.

Diagnosis and Treatment of Pituitary Adenomas

Mark Molitch (2017)

Pituitary adenomas may hypersecrete hormones or cause mass effects. Therefore, early diagnosis and treatment are important.

Diagnosis and treatment of hyperprolactinemia: an Endocrine Society clinical practice guideline.

Shlomo Melmed, Felipe Casanueva, Andrew R. Hoffman … (2011)

The aim was to formulate practice guidelines for the diagnosis and treatment of hyperprolactinemia. The Task Force consisted of Endocrine Society-appointed experts, a methodologist, and a medical writer. This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system to describe both the strength of recommendations and the quality of evidence. One group meeting, several conference calls, and e-mail communications enabled consensus. Committees and members of The Endocrine Society, The European Society of Endocrinology, and The Pituitary Society reviewed and commented on preliminary drafts of these guidelines. Practice guidelines are presented for diagnosis and treatment of patients with elevated prolactin levels. These include evidence-based approaches to assessing the cause of hyperprolactinemia, treating drug-induced hyperprolactinemia, and managing prolactinomas in nonpregnant and pregnant subjects. Indications and side effects of therapeutic agents for treating prolactinomas are also presented.

Endoscopic skull base reconstruction of large dural defects: a systematic review of published evidence.

Alan R. Harvey, Jayshree Parmar, Adam Zanation … (2012)

Systematically review the outcomes of endoscopic endonasal techniques to reconstruct large skull base defects (ESBR). Such surgical innovation is likely to be reported in case series, retrospective cohorts, or case-control studies rather than higher level evidence. Systematic review and meta-analysis. Embase (1980-December 7, 2010) and MEDLINE (1950-November 14, 2010) were searched using a search strategy designed to include any publication on endoscopic endonasal reconstruction of the skull base. A title search selected those articles relevant to the clinical or basic science of an endoscopic approach. A subsequent abstract search selected articles of any defect other than simple cerebrospinal fluid (CSF) fistula, sella only, meningoceles, or simple case reports. The articles selected were subject to full-text review to extract data on perioperative outcomes for ESBR. Surgical technique was used for subgroup analysis. There were 4,770 articles selected initially, and full-text analysis produced 38 studies with extractable data regarding ESBR. Of these articles, 12 described a vascularized reconstruction, 17 described free graft, and nine were mixed reconstructions. Three had mixed data in clearly defined patient groups that could be used for meta-analysis. The overall CSF leak rate was 11.5% (70/609). This was represented as a 15.6% leak rate (51/326) for free grafts and a 6.7% leak rate (19/283) for the vascularized reconstructions (χ(2) = 11.88, P = .001). Current evidence suggests that ESBR with vascularized tissue is associated with a lower rate of CSF leaks compared to free tissue graft and is similar to reported closure rates in open surgical repair.
