Doctor: Prof. MD. Caglayan Geredeli Hospital: ISU Medical Park Gaziosmanpaşa

As a 78-year-old with metastatic prostate cancer that had stopped responding to standard treatments, I felt I was out of options. Prof. Geredeli didn't see a terminal case; he saw a puzzle. He proposed a novel combination therapy based on recent research he'd been following from a conference in Singapore. He explained the mechanism, how it would target a specific mutation my previous oncologist hadn't even tested for. The treatment wasn't easy, but he managed my side effects with such precision. Six months later, my PSA is undetectable for the first time in years. He doesn't just administer protocols; he designs strategies. He gave me back my mornings in the garden with my wife.

Doctor: Prof. MD. Caglayan Geredeli Hospital: ISU Medical Park Gaziosmanpaşa

Our 9-year-old daughter was diagnosed with a rare desmoplastic small round cell tumor. The local hospital was overwhelmed. From our first emergency admission at ISU Medical Park, Prof. Geredeli took control with a calm, commanding presence that immediately eased our panic. He coordinated a same-day multidisciplinary meeting with pediatric surgeons, radiologists, and the pathology lab. What struck me was how he spoke directly to our daughter, explaining her 'superhero cells' and the 'special medicine' plan in a way she understood. He pioneered an adapted adult protocol for her, monitoring her with daily visits during the intense phases. We're now in follow-up, and he still remembers her favorite cartoon character. He fought for her childhood as fiercely as he fought the cancer.

Doctor: Prof. MD. Caglayan Geredeli Hospital: ISU Medical Park Gaziosmanpaşa

I came for a routine second-opinion consultation after my breast cancer diagnosis, expecting a quick review. Instead, Prof. Geredeli spent two hours deconstructing my biopsy report. He noticed a subtle immunohistochemistry pattern others missed, suggesting a borderline HER2 status. He personally walked my slides to the pathology department for a FISH test, which confirmed his suspicion. This changed everything, it made me eligible for a targeted therapy. His approach isn't a consultation; it's an investigation. He listens with intense focus, his questions peeling back layers you didn't know were there. He doesn't treat a diagnosis; he treats the unique biological story of your tumor.

Doctor: Prof. MD. Caglayan Geredeli Hospital: ISU Medical Park Gaziosmanpaşa

Following a complex cytoreductive surgery and HIPEC for peritoneal mesothelioma, my follow-up care felt like navigating a minefield. Prof. Geredeli transformed these visits into a masterclass in proactive management. He uses a custom digital dashboard tracking not just my scans, but my nutritional markers, neuropathy scores, and even quality-of-life metrics. Last visit, he spotted a slight trend in my liver enzymes before I felt any symptoms, adjusted my supportive medications, and prevented a serious complication. He has a visionary approach, he's not just looking for recurrence; he's optimizing my entire system to resist it. His clinic feels less like a hospital and more like a mission control center for survivorship.
