Professor Sezer Saglam is one of Turkey’s leading medical oncologists, with more than 25 years of clinical experience in chemotherapy and drug treatment of cancer. He works at the Oncology Center of the Florence Nightingale Hospitals Group in Gayrettepe (Istanbul) — a comprehensive oncology clinic with its own molecular oncology laboratory, PET-MRI equipment and gamma knife, where precision (personalized) medicine technologies and the selection of targeted therapy based on the genetic profiling of the tumor are applied.
He is one of Turkey’s leading specialists in the medical oncology of the gastrointestinal tract. He is the author of the “Istanbul R-01 Study” — an original prospective randomized trial on the optimal timing of surgery after neoadjuvant chemoradiotherapy for rectal cancer, presented at the annual conference of the American Society of Clinical Oncology (ASCO) in 2009. In 2024 he was awarded the International Best Researcher Award for his scientific work on patients with hepatocellular carcinoma (liver cancer) after liver transplantation.
Why patients choose Professor Saglam:
Professor Sezer Saglam sees patients in person at the Florence Nightingale Gayrettepe Hospital, and if necessary an online consultation is possible.

The clinic is equipped with PET-MRI technology for oncological diagnostics. The center includes its own molecular oncology laboratory, where all the necessary genetic tests on tumor tissue are performed to select targeted therapy, as well as a Center for the Diagnosis of Genetic Diseases.
