Prof. A.Sibel Erdamar Çetin, MD

Prof. A.Sibel Erdamar Çetin, MD is a pathology specialist at Acibadem Atakent Hospital in İstanbul, where she works in the Pathology Department. Her work centers on the diagnostic evaluation of tissue and laboratory specimens, with a particular focus on gastrointestinal cancer pathology. She has more than 35 years of experience in medicine, and her findings support the clinicians who plan further evaluation and treatment for their patients.

Dr. Çetin graduated from Ankara University Faculty of Medicine in 1991 and completed her specialty training in pathology at İstanbul University Cerrahpaşa Faculty of Medicine in 1995. She has been part of Acıbadem Healthcare Services since 2018. She holds the academic title of professor.

Clinical focus

Dr. Çetin’s clinical work covers diagnostic pathology in a broad sense, from routine diagnostic pathology to the review of complex cases. Histopathologic diagnosis is the core of this work: tissue samples obtained through biopsies or surgical procedures are examined under the microscope so that a pathological diagnosis can be established. This diagnosis forms part of the information that treating physicians use when deciding on next steps, and it is one element of a wider clinical assessment rather than a standalone result.

Within this field, gastrointestinal cancer pathology is a particular area of expertise. Dr. Çetin also takes part in multidisciplinary cancer case management, in which pathologists, surgeons, oncologists and other specialists discuss individual cases together. Complex case pathology review is another aspect of her work; this may involve re-examining existing slides or specimens when a diagnosis is uncertain or when additional confirmation is needed before treatment decisions are made. The outcome of such a review depends on the quality and completeness of the material available, and in some situations further sampling or additional tests may be suggested by the treating team.

How Dr. Çetin works with international patients

Dr. Çetin speaks Turkish and English, and interpreters can be arranged for patients who need support in other languages. Because pathology relies on existing material, the Acibadem international patient team coordinates the collection of prior reports and imaging, including pathology results, laboratory findings, MRI, CT, X-ray or ultrasound reports, operative notes and discharge summaries, and arranges appointments and the hospital visit. A first consultation typically covers the patient’s history and symptoms, a review of existing imaging, pathology findings and previous treatments, a clinical examination where relevant, and a discussion of the available options. Video consultation is available for international patients who wish to discuss their pathology findings or the possibility of a case review before or instead of traveling; whether a full assessment can be completed remotely depends on the material available and the individual situation.
