Prof. Mahir Özmen is one of the highly acknowledged Oncosurgeons of Turkey alongside his academic accomplishments that makes him a recognized international surgeon. He has published over 200 research papers with 4000 citations that carry himself to a very high H-index which is an international measure of academic performance.
He holds many international titles including the American Society of Metabolic and Bariatric Surgery (ASBMS), Fellow of Royal College of Surgeons Glasgow FRCSİ, Fellow of European Board of Surgery FEBS, etc. and acts as an international teaching and governing surgeon who trains surgeons from all around the world.
Prof. Özmen speaks about the surgical oncology procedure and he actually divides into two main categories, tumors in the upper GI (gastrointestinal) and tumors in the lower GI due to different surgical approach and techniques. Whatever the type of surgery is, the target of it should be to create a tumor-free resection (R0) where the surgeon leaves no cells of tumor behind.
If it is R1, it means micro-tumors are left behind where you can’t see the tumor left behind with the naked eye and if it is R2 it means you can still see the tumor left behind. In these cases, radio or chemotherapy is required after the initial procedure. So Prof. Mahir Özmen specifies his main goal is curative surgery, which means to do extensive surgery in order to leave no tumor behind.
Among surgical oncology procedures, Prof. Mahir places great importance on HIPEC, being an advanced treatment option especially for advanced gastrointestinal tumors and gynecological tumors. HIPEC is required for stage 3 and stage 4 patients with peritoneal deposits and layers of the internal abdomen are removed in a prior procedure named ‘Peritonectomy’ that separates the abdomen from the peritoneum. Then special HIPEC agents are applied inside the abdomen to decrease the chances of metastasis.
Prof. Mahir Özmen states that HIPEC can be done via laparoscopic procedure but he prefers open surgery for HIPEC at which he can perform extensive surgery.
“Yes, the number of cases of the surgeon who perform the procedure is very important, but it is not everything”
Although he has performed a huge number of cases in oncosurgery, Prof. Mahir Özmen prefers to emphasize the importance of “being complete” rather than being “only a technician”, underlying reading, writing, and strengthening the academic side.
“You need Best Surgeon, very well-equipped hospital, a talented and well-educated team of surgery in order to overcome any complications”
