The trans-sphenoidal resection of pituitary adenomas in elderly patients and surgical risk

In western countries, the process of “ageing of the population” is increasingly forcing clinical medicine to find answers for pathologies affecting the elder segments of our community. In this respect, pituitary adenomas often raise difficult questions on surgical indications, since little is known about postoperative morbidity and mortality in elderly patients. The transsphenoidal endonasal approach (TNS), which is considered the gold standard for surgical resection of the majority of functioning and non-functioning pituitary adenomas, is supposed to be a low morbidity and mortality procedure in adult patients. However, only a few contradicting data are available in the literature about elderly patients. In this paper we retrospectively analyze a cohort of 43 consecutive patients aged more than 65 years, operated on for pituitary adenomas at our Institution in the years 1998–2007. These patients were treated by transsphenoidal endonasal approach (TNS) for resection of non-functioning pituitary adenomas (n = 31), GH-secreting adenomas (n = 4) and ACTH-secreting adenomas (n = 8). Clinical records reported a macroadenoma with tumour-related mass symptoms in about 80 % of patients; single or multiple pituitary deficits were present in 44 % of patients. Regarding comorbidities, cardiac disease was the most frequently observed (86 %); assessment of anaesthesiological risk indicated a moderate to severe ASA score in most patients, 11 % showing a 4–5 score. On the basis of current criteria, our retrospective analysis revealed that cure was achieved in 54 % of patients. The outcome was similar to that observed in the general population of patients undergoing transphenoidal surgery in our centre, without differences in the rate of surgical and endocrinological cure, minor and major surgical complications and hospitalization duration. In particular, no significant anaesthesiological complications were observed and no patient developed either permanent diabetes insipidus or cerebrospinal fluid rhinorrhea. In conclusion, in specialized centres the surgical treatment of pituitary adenomas via the transsphenoidal route can be a safe and effective procedure even in elderly patients.

Evaluation of the pituitary-adrenal axis before, during and after pituitary adenomectomy. Is perioperative glucocorticoid therapy necessary?

Under the supposition that ACTH secretion will be compromised by surgical trauma, patients with pituitary adenomas undergoing transsphenoidal adenomectomy are frequently given corticoids, even though this therapy is controversial. We studied 10 patients with pituitary adenomas whose adrenocortical function was sufficient prior to surgery. The ACTH and cortisol levels rose significantly during surgery in all of these patients. Five patients completed a two-year postoperative follow-up period and their ACTH and cortisol values remained within normal limits. It may be that patients undergoing transsphenoidal surgery for pituitary adenomas do not need perioperative glucocorticoid treatment, since the hypophyseal-adrenal axis does retain its integrity.     

Gamma knife radiosurgery for pituitary adenomas

Although surgical extirpation by transsphenoidal microsurgery is a major remedy for pituitary adenomas, adjuvant therapy also plays an important role in achieving tumor growth control and endocrine normalization in hormone-secreting tumors. Historically, the treatment options for pituitary adenomas included microsurgery, medical management, and fractionated radiotherapy, but radiosurgery has recently emerged as a practical treatment option. In this paper, we will describe the indications, radiosurgical procedure, results, histological change, and complications of gamma knife radiosurgery (GKS) for pituitary adenomas based on our experience since 1991 and a review of the literature.     

Endoscopic endonasal compared with microscopic transsphenoidal and open transcranial resection of giant pituitary adenomas

Giant (>4 cm) pituitary macroadenomas often require surgery to decompress the optic nerves. Compared with traditional open or transsphenoidal microscopic methods, the extended endoscopic endonasal transsphenoidal approach offers the potential for aggressive resection via a minimal access corridor. We conducted a systematic review of the literature to further our understanding of the role of endoscopy in the management of these challenging lesions. MEDLINE search of the modern literature (1995-2010) to identify surgical series for pediatric and adult pituitary adenomas >4 cm in maximal diameter. Patient and tumor characteristics, resection, morbidity and visual outcome were compared by approach. Chi-square and Fisher's exact tests with post-hoc Bonferroni analysis were used for statistical analyses. Sixteen studies (478 patients) were included. Compared with the open cohort, the endoscopic cohort had higher rates of gross total resection (47.2% vs. 9.6%; P < 0.003) and improved visual outcome (91.1% vs. 45.7%; P < 0.003). The microscopic transsphenoidal cohort had lower rate of total resection and worse visual outcomes than the endoscopic group. There were no instances of postoperative CSF leak reported in the endoscopic group. The transcranial group had a higher rate perioperative mortality compared to the transsphenoidal group (P = 0.004). In select cases, the endoscopic endonasal approach is safe and effective for the treatment of giant pituitary adenomas, with the potential for gross total resection and improved visual outcome. CSF leak, which is a major limitation of the endonasal approach, may be avoided using meticulous multi-layer closure and vascularised nasoseptal flaps.
