Contemporary management of clival chordomas

Area of Science:

• Oncology
• Neurosurgery
• Molecular Biology

Background:

• Clival chordomas are rare, locally aggressive malignant tumors with a poor prognosis.
• Their unique biology and proximity to critical neurovascular structures present significant treatment challenges.

Purpose of the Study:

• To review current literature on clival chordoma management strategies.
• To provide guidelines for optimal treatment of this aggressive tumor.

Main Methods:

• Literature review of existing studies on clival chordoma.
• Analysis of diagnostic and therapeutic approaches, including surgical and radiation techniques.
• Evaluation of molecular markers and their therapeutic potential.

Main Results:

• Molecular advancements, including chordoma cell lines and the brachyury transcription factor, are crucial for diagnosis and therapeutic development.
• Aggressive cytoreductive surgery for gross total resection, preserving neurovascular structures, followed by proton beam or hadron radiation, yields the best survival rates.
• The brachyury transcription factor shows potential as a diagnostic marker and therapeutic target.

Conclusions:

• Optimal management of clival chordomas requires a multidisciplinary approach, combining aggressive surgery with postoperative radiation.
• Preservation of key neurovascular structures during surgery is paramount.
• Advancements in molecular techniques offer promising future avenues for diagnosis and treatment of chordomas.
