Sefik Igdem

Dr. Sefik Igdem is a radiation oncologist at Istanbul Florence Nightingale Hospital. He specializes in conformal treatments. The doctor is among the first to implement intensity-modulated and image-guided radiotherapy techniques. He treats patients using specialized oncological protocols developed over his career.

Specialization and Clinical Focus

Dr. Igdem treats prostate cancer and head and neck cancers. He uses 3D conformal radiation therapy to target tumors with precision. This approach limits radiation exposure to the healthy tissues surrounding the tumor site. He also performs intensity-modulated radiation therapy (IMRT) — a method that matches radiation beams to the tumor shape.

The doctor introduces technologies in radiation oncology to improve care. He applies image-guided radiotherapy (IGRT) to account for organ movement during treatment. IGRT uses frequent imaging during therapy to ensure the beam hits the cancer precisely. His practice improves patient outcomes through evidence–based radiation methods.

Research and Academic Contributions

Dr. Igdem conducted a retrospective analysis of 600 postmenopausal breast cancer cases. This research evaluated the combined effects of postoperative radiotherapy and tamoxifen. His work provides data for treating breast cancer in older patient populations. He integrates clinical research into daily oncology care.
