Prof. M.D. Gökhan Demir

My 82-year-old father was diagnosed with metastatic prostate cancer after months of vague symptoms. Dr. Demir approached his case not just as an oncologist, but as someone who understood the complexities of treating the elderly. He created a tailored regimen that balanced aggression with quality of life, explaining every step in simple Turkish while showing my father genuine respect. What stood out was his coordination with geriatric specialists at Acibadem Maslak—managing bone health, nutrition, and even sleep patterns alongside the cancer treatment. After six months, my father's markers improved significantly, and he still tends his small garden. Dr. Demir treats the person, not just the disease.

Our 7-year-old daughter's leukemia relapse felt like the end of the world. Dr. Demir met us in the pediatric oncology wing with a calm that immediately settled our panic. He didn't just present protocols; he drew diagrams showing how CAR-T cell therapy works, making our daughter part of the conversation by calling her 'the chief scientist.' His team managed her cytokine release syndrome with round-the-clock attention at Maslak Hospital, and Dr. Demir visited twice daily, sometimes just to share a silly joke. Eight months in remission now, and she still draws pictures for 'Dr. Gökhan.' He navigates the terrifying world of pediatric oncology with both brilliant science and profound heart.

I arrived at Acibadem Maslak as an emergency transfer with superior vena cava syndrome from undiagnosed lung cancer—struggling to breathe, swollen, terrified. Dr. Demir's team acted within minutes: steroids, immediate imaging, and a same-day stent procedure to relieve the obstruction. What followed was masterful crisis management—stabilizing me while simultaneously launching a full diagnostic workup. Within 72 hours, I had a complete molecular profile of my cancer and a targeted therapy plan. Dr. Demir's ability to handle acute oncology emergencies while building a long-term strategy saved my life twice over. His precision under pressure is something I'll never forget.

As a 45-year-old with BRCA2 and a complex family cancer history, my routine surveillance MRI revealed a subtle pancreatic lesion. Dr. Demir didn't dismiss it as 'probably nothing' nor did he cause unnecessary alarm. He orchestrated a multidisciplinary review with surgeons, radiologists, and genetic counselors—all within Acibadem Maslak's system. His approach was methodical: EUS, liquid biopsy, and genetic sequencing of the lesion before any intervention. The lesion proved to be a very early-stage cancer, and his team performed a minimally invasive Whipple procedure. Now two years into follow-up, my surveillance feels like a partnership rather than a passive process. Dr. Demir transforms routine checkups into sophisticated prevention.
