ABSTRACT We conducted a systematic review and meta-analysis of randomized and non-randomized controlled trials that compared pure endoscopic with microscopic transsphenoidal surgery (TSS) in the resection of pituitary tumors. Embase, PubMed, Lilacs, and Central Cochrane were used as our data sources. The outcomes were total tumor resection, achievement of biochemical control of functioning adenomas, hospital stay and surgery complications. The randomized trials were analyzed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Two randomized and three prospective controlled non-randomized studies were included. Two studies, including 68 patients, evaluated total tumor resection and the meta-analysis did not show differences between the groups [RR: 1.45 (95% CI: 0.87, 2.44)]. Three studies involving 65 patients analyzed the achievement of biochemical control and no statistical difference was found [RR: 0.94 (95% CI: 0.7, 1.26)]. All five studies compared the frequency of postoperative complications between intervention and control group and meta-analysis favored for a low rate of postoperative complications in the endoscopic TSS group [(RR: 0.37 (95% CI: 0.16, 0.83)]. Due to the low evidence level and low number of observations, the results of our meta-analysis should not be viewed as a final proof of inferiority or superiority of one approach in relation to the other. More data including higher numbers of observations are needed.

ABSTRACT
BACKGROUND: The anterior skull base is an uncommon site for brain metastases. A limited number of cases have been reported where a region of the skull base is accessed through an expanded/extended transsphenoidal route. In addition, reports of overall and progression-free survival rates are lacking. OBJECTIVE: To report progression-free and overall survival rates for skull base metastases treated with aggressive endoscopic endonasal surgery and radiation therapy. METHODS: We retrospectively review a prospective database of patients at New York Presbyterian Hospital undergoing expanded endoscopic endonasal surgery from 2004 to 2014. From this database, we identified all patients whose final pathology revealed a metastatic lesion in the midline skull base. RESULTS: Seven hundred forty-nine patients underwent endonasal endoscopic surgery. Final pathology in 12 patients (1.6%) revealed metastasis to the sellar or parasellar region. Tumors were located in the sella, suprasellar cistern, clivus, ethmoid sinuses, sphenoid sinus, cavernous sinus, and craniovertebral junction. Breast and lung cancers were the most common primary diagnoses. Gross total resection was achieved in 41.6% of patients. There were no postoperative cerebrospinal fluid leaks. Adjuvant radiation therapy was used in 92% of cases. Median follow-up was 14 months (range, 1-55). Median progression-free and overall survival were 18 and 16 months, respectively. CONCLUSIONS: The range of anterior skull base metastatic lesions that can be managed endonasally has increased with the advent of extended endonasal endoscopic surgical approaches. Favorable results can be obtained with this surgical approach as part of the overall management paradigm for patients with skull base metastases.
