Dear Colleagues and Friends,

On behalf of the Taiwan Society for Neuro-Oncology, it is my great pleasure to welcome you to the 2025 Taiwan Neuro-Oncology & Skull Base Society International Symposium. This year's theme, "Recurrent Brain Tumors: Innovation and Breakthroughs," addresses one of the most challenging aspects of our field.

The management of recurrent brain tumors requires multidisciplinary collaboration and innovative approaches. In recent years, we have witnessed remarkable progress in molecular diagnostics, targeted therapies, and surgical techniques. This conference will showcase these advancements through keynote lectures, expert panels, and interactive workshops.

I particularly encourage young researchers and clinicians to participate actively in our Young Investigator Forum. Your fresh perspectives and innovative ideas are crucial for advancing our field.

I look forward to welcoming you to this exciting scientific exchange.

Dear Esteemed Colleagues,

As President of the Taiwan Society for Skull Base Surgery and on behalf of our local organizing committee at Chang Gung Memorial Hospital, I am honored to co-host this important international symposium focused on recurrent brain tumors.

Skull base tumors present unique challenges when they recur, often requiring specialized surgical approaches and multidisciplinary management. This conference will highlight cutting-edge techniques in skull base surgery, including endoscopic approaches, intraoperative imaging, and nerve preservation strategies.

Chang Gung Memorial Hospital has been at the forefront of skull base surgery in Asia, and we are proud to share our experience through live surgical demonstrations and case discussions during the conference.

We look forward to welcoming you to our institution and to fruitful scientific exchanges.

Dear Participants,

As Conference President, it is my privilege to welcome you to this important gathering of neuro-oncology and skull base surgery experts from around the world. The theme of recurrent brain tumors is particularly timely, as we face increasing challenges in managing these complex cases.

This conference has been carefully designed to provide practical, clinically relevant knowledge that you can apply immediately in your practice. From molecular diagnostics to innovative surgical techniques and novel therapeutic approaches, we have assembled an outstanding program that addresses the full spectrum of recurrent brain tumor management.

I encourage you to take full advantage of the networking opportunities during the conference. Some of the most valuable insights often come from informal discussions with colleagues facing similar challenges.

We are committed to making this conference a memorable and productive experience for all participants.

Dear Friends and Colleagues,

As Secretary General of this conference, I am delighted to welcome you to what promises to be an outstanding scientific meeting. Our organizing committee has worked diligently to create a program that balances cutting-edge science with practical clinical applications.

The abstract submission process was highly competitive this year, reflecting the growing interest in recurrent brain tumor research. I congratulate all authors whose work was accepted for presentation and encourage all participants to engage actively with the presenters.

For our international guests, we have arranged special social events to introduce you to Taiwanese culture and cuisine. These informal gatherings often lead to lasting professional collaborations and friendships.

Please don't hesitate to approach any member of our organizing committee if you need assistance during the conference. We are here to ensure your experience is both productive and enjoyable.
