Although histologically benign, these tumors are locally aggressive&lt;/p&gt;&lt;font face=&quot;TimesNewRomanPSMT&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;TimesNewRomanPSMT&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;TimesNewRomanPSMT&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;TimesNewRomanPSMT&quot; size=&quot;2&quot;&gt;&lt;p&gt;and present significant managment challenges . There arew some studies on&lt;/p&gt;&lt;/font&gt;&lt;/font&gt;&lt;p&gt;&lt;/p&gt;&lt;p align=&quot;left&quot;&gt;evaluated the location, age and gender of the patients with Chordoma in two&lt;/p&gt;&lt;p align=&quot;left&quot;&gt;referral centers in Tehran.&lt;/p&gt;&lt;/font&gt;&lt;/font&gt;chordoma cases but there was no study about Iranian cases. In this study we&lt;/font&gt;&lt;/font&gt;&lt;font face=&quot;TimesNewRomanPSMT&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;TimesNewRomanPSMT&quot; size=&quot;2&quot;&gt;Skull base chordomas are rare neoplasms arising from the&lt;/font&gt;&lt;/font&gt;&lt;b&gt;&lt;font face=&quot;TimesNewRomanPS-BoldMT&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;TimesNewRomanPS-BoldMT&quot; size=&quot;2&quot;&gt;&lt;p align=&quot;left&quot;&gt;Methods: &lt;/p&gt;&lt;p align=&quot;left&quot;&gt;(Shariati and Imam Hospitals, Tehran) from 2001 to 2011 was retrospectively&lt;/p&gt;&lt;p align=&quot;left&quot;&gt;reviewed.&lt;/p&gt;&lt;/font&gt;&lt;/font&gt;&lt;font face=&quot;TimesNewRomanPSMT&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;TimesNewRomanPSMT&quot; size=&quot;2&quot;&gt;A database of patients with chordoma tumors referred to two centers&lt;/font&gt;&lt;/font&gt;&lt;b&gt;&lt;font face=&quot;TimesNewRomanPS-BoldMT&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;TimesNewRomanPS-BoldMT&quot; size=&quot;2&quot;&gt;&lt;p align=&quot;left&quot;&gt;Results: &lt;/p&gt;&lt;p align=&quot;left&quot;&gt;women, and they are most commonly diagnosed in middle-aged (mean age was&lt;/p&gt;&lt;p align=&quot;left&quot;&gt;50.6). Tumors typically occur in the axial skeleton and have a tendency for the&lt;/p&gt;&lt;p align=&quot;left&quot;&gt;spheno-occipital region of the skull base and sacral region. In adults 33.3% of&lt;/p&gt;&lt;p align=&quot;left&quot;&gt;chordomas involve the sacrococcygeal region, 53% occured at the base of the&lt;/p&gt;&lt;p align=&quot;left&quot;&gt;skull near the spheno-occipital area, and near 14% were found in the vertebral&lt;/p&gt;&lt;p align=&quot;left&quot;&gt;column. The cranial nerves mostly affected were abducens, oculomotor and&lt;/p&gt;&lt;p align=&quot;left&quot;&gt;trochlear, with some overlaps. All patients were treated with surgery and some&lt;/p&gt;&lt;p align=&quot;left&quot;&gt;cases referred for gamma-knife radiosurgery (GKS).&lt;/p&gt;&lt;/font&gt;&lt;/font&gt;&lt;font face=&quot;TimesNewRomanPSMT&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;TimesNewRomanPSMT&quot; size=&quot;2&quot;&gt;In our subjects tumors affect men nearly twice as frequently as&lt;/font&gt;&lt;/font&gt;&lt;b&gt;&lt;font face=&quot;TimesNewRomanPS-BoldMT&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;TimesNewRomanPS-BoldMT&quot; size=&quot;2&quot;&gt;&lt;p align=&quot;left&quot;&gt;Discussion: &lt;/p&gt;&lt;p align=&quot;left&quot;&gt;to females that is different from other studies, however, few studies reported&lt;/p&gt;&lt;p align=&quot;left&quot;&gt;more male to female ratio. Despite the progress in current surgical techniques&lt;/p&gt;&lt;p align=&quot;left&quot;&gt;and some encouraging results with the use of targeted therapy, disease control&lt;/p&gt;&lt;p&gt;and long-term prognosis of patients are still poor.&lt;/p&gt;&lt;/font&gt;&lt;/font&gt;&lt;font face=&quot;TimesNewRomanPSMT&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;TimesNewRomanPSMT&quot; size=&quot;2&quot;&gt;Findings of this study showed more involvement of males compare&lt;/font&gt;&lt;/font&gt;&lt;/b&gt;&lt;/b&gt;&lt;/b&gt;&lt;/b&gt;</abstract>
