Oncology Center and Specialized Cancer Treatment
Oncology is one of the prominent areas of medical care at Gayrettepe Hospital. The hospital has medical oncology and radiation oncology departments, in addition to nuclear medicine and advanced medical imaging services.
The hospital's official website indicates that it has an advanced oncology center that can provide individualized treatment approaches based on the patient's disease and clinical condition. Depending on the medical indication, treatment may include targeted therapies and biological therapies.
However, the availability of these treatment options does not mean that every cancer patient is eligible for them. Treatment selection depends on factors such as the type and stage of the tumor, its molecular characteristics, diagnostic findings, and the assessment of the treating medical team.
Medical Imaging and PET-MR Technology
The hospital uses advanced imaging and diagnostic technologies, including PET-MR.
PET-MR combines the functional information provided by positron emission tomography (PET) with the detailed anatomical images produced by magnetic resonance imaging (MRI).
This technology may be used to evaluate certain conditions, particularly in oncology, neurological disorders, and selected cardiovascular conditions, depending on the patient's medical situation and the diagnostic objective.
The hospital also provides radiology and medical imaging services that support diagnosis and follow-up across different specialties.
Gamma Knife Technology
Gayrettepe Hospital has a Gamma Knife system, a form of stereotactic radiosurgery used to treat certain intracranial lesions without conventional open surgery in selected cases.
Whether Gamma Knife is appropriate depends on factors such as the nature, location, and size of the lesion, the final diagnosis, and the assessment of the neurosurgery and radiation oncology teams.
International patients considering Gamma Knife treatment should therefore send their medical records and imaging studies before traveling so that the medical team can assess whether the technology is suitable for their particular condition.
Nuclear Medicine
The hospital has a nuclear medicine department providing both diagnostic and therapeutic services.
Nuclear medicine plays an important role in the assessment of several diseases, including certain types of cancer. It is also associated with functional imaging techniques that can help physicians evaluate disease activity and plan treatment and follow-up.
Endoscopy and Bronchoscopy
The hospital provides endoscopy and bronchoscopy units.
These units are used for the diagnosis and follow-up of various gastrointestinal and respiratory conditions. Depending on the patient's condition, procedures may be diagnostic or therapeutic.
Having these services within the same hospital can be particularly useful for patients who need to complete multiple diagnostic examinations within a single medical facility.
Laboratories and Diagnostic Services
Gayrettepe Hospital has a range of laboratories and diagnostic units supporting its medical and surgical departments.
These include:
-
Pathology Laboratory.
-
Histology and Immunology Laboratory.
-
Biochemistry Laboratory.
-
Microbiology Laboratories.
-
Genetic Disease Diagnosis Center.
The pathology laboratory plays an essential role in the analysis of tissues and cells, which is particularly important in cancer diagnosis and in determining the nature of certain diseases.
The histology and immunology services are associated with immunological assessments and tissue typing required for certain medical procedures, including selected organ and tissue transplantation evaluations.
Pediatric and Neonatal Services
The hospital provides a range of pediatric services, including several pediatric subspecialties.
Published services include:
-
Pediatrics.
-
Pediatric Gastroenterology.
-
Pediatric Cardiology.
-
Pediatric Nephrology.
-
Neonatology.
According to the officially published capacity information, the hospital has five neonatal intensive care beds.
For international patients traveling with children, it is important to identify the required pediatric subspecialty before traveling and confirm that the appropriate physician and unit will be available at the requested time.
Cardiology and Pediatric Cardiology
The hospital has a cardiology department as well as a pediatric cardiology specialty.
The availability of technologies such as PET-MR and nuclear medicine also provides diagnostic capabilities that may be used in selected cardiovascular cases when clinically indicated.
However, the availability of these technologies does not mean that every cardiac patient requires them. The physician determines the appropriate diagnostic examination based on the patient's symptoms, diagnosis, and clinical condition.
Neurosurgery
The hospital provides neurosurgical services supported by advanced diagnostic and therapeutic technologies such as Gamma Knife and PET-MR.
These technologies are used according to the individual medical condition, and their availability does not mean that all brain or nervous system disorders are treated using the same approach.
International patients considering neurosurgery should send previous imaging studies and diagnostic reports before traveling so that the medical team can conduct an initial assessment of the case.
Orthopedics and Hand Surgery
The hospital provides orthopedic and traumatology services, as well as hand surgery as a separate specialty.
These services cover the assessment and treatment of a range of orthopedic conditions, injuries, and disorders affecting the hand and wrist, depending on the patient's diagnosis and individual condition.
Obstetrics and Gynecology
The hospital has an obstetrics and gynecology department, supported by neonatal and pediatric services.
International patients traveling for childbirth or treatment of a gynecological condition should obtain a clear plan before traveling. This should include the required examinations, the responsible physician, the expected length of stay, and the follow-up plan after childbirth or the procedure.
JCI Accreditation and Quality Certifications
Information regarding JCI accreditation at Florence Nightingale Gayrettepe Hospital requires particular care because the Florence Nightingale Group operates several hospitals, and the accreditation status of one facility should not be attributed to another.
The official Florence Nightingale Group website states that Gayrettepe Hospital historically obtained JCI accreditation. The hospital's current website also refers to ISO and JCI quality certifications.
At the same time, the current JCI accreditation page published on the group's website, which displays certificates for the periods 2013–2016, 2016–2019, 2019–2022, 2022–2025, and 2025–2028, identifies the facility as Florence Nightingale Istanbul Hospital rather than Gayrettepe Hospital.
Therefore, it would not be accurate to state that Gayrettepe Hospital currently holds JCI accreditation for the 2025–2028 period based solely on that page.
The more accurate wording is that the hospital has a documented history of JCI accreditation and that its current official website refers to ISO and JCI certifications. However, the current 2025–2028 JCI certificate published on the group's website should be distinguished from Gayrettepe Hospital because it is listed under Florence Nightingale Istanbul Hospital.
What JCI Accreditation Means for Patients
JCI accreditation involves the evaluation of a healthcare facility against international standards related to the quality and safety of patient care.
Accreditation standards commonly cover areas such as patient safety, medication management, infection prevention and control, communication with patients, information management, and continuity of care.
However, JCI accreditation does not guarantee a treatment outcome or mean that every medical procedure is appropriate for every patient. It also does not replace an individual medical assessment by a qualified physician.
International patients should therefore consider accreditation as one factor when evaluating a hospital, alongside the experience of the medical team, the required specialty, available technology, and the proposed treatment plan.
International Patient Services
The Florence Nightingale Group provides dedicated services for international patients through its International Patient Center. Gayrettepe Hospital is included among the group's facilities serving patients from abroad.
The International Patient Center assists with coordinating the patient's medical journey, including medical record review, physician coordination, appointment scheduling, and assistance with treatment-related procedures.
The group also provides translation and support services for international patients and their companions and states that its international patient team provides assistance around the clock.
Translation and Communication Services
According to information published on HealthTürkiye, Gayrettepe Hospital provides services in nine languages.
The Florence Nightingale Group also has an international patient team that includes multilingual interpreters who can support patients and their companions during treatment.
Nevertheless, patients should confirm before traveling that an interpreter who speaks their preferred language will be available for their specific appointment, particularly when discussing surgery, signing informed consent documents, or reviewing a treatment plan.
Medical Evaluation Before Traveling
International patients can benefit from submitting their medical records before traveling, particularly when the purpose of the trip is surgery, cancer treatment, or another specialized medical intervention.
The medical file may include:
-
A recent medical report.
-
Previous diagnoses.
-
Laboratory test results.
-
Imaging studies.
-
MRI or CT reports.
-
PET scans and reports, when available.
-
Biopsy and pathology reports in oncology cases.
-
A list of current medications and dosages.
-
Reports from previous surgeries.
-
Hospital discharge summaries.
-
Cardiology, gynecology, or pediatric reports, depending on the condition.
Submitting the medical file in advance allows the medical team to identify the appropriate specialty and determine which examinations may be required after the patient arrives.
Medical Records Required Before Traveling
The medical file submitted before travel should be organized and up to date and should contain all information necessary for the physician to understand the patient's condition.
For oncology cases, it is particularly important to provide biopsy and pathology reports as well as previous imaging studies because treatment decisions depend on an accurate diagnosis and the specific characteristics of the tumor.
For surgical cases, previous operative reports, imaging studies, medication lists, and information regarding chronic diseases or medication allergies can also be useful.
Important Points Before Booking Surgery
Before booking travel or paying for treatment, international patients should confirm:
-
The exact name of the hospital where the procedure will be performed.
-
The relevant medical department.
-
The physician's specialty.
-
The type of surgery or procedure.
-
The technology or technique to be used.
-
The type of anesthesia.
-
The examinations required before surgery.
-
The expected length of hospital stay.
-
Whether intensive care may be required.
-
The medications and medical supplies included in the quotation.
-
The follow-up plan after the procedure.
-
Whether additional costs may apply.
It is particularly important to confirm that the procedure will be performed specifically at Gayrettepe Hospital, rather than at another hospital belonging to the Florence Nightingale Group.
What the Medical and Financial Package Should Include
The quotation provided to an international patient should be clear and detailed and should specify exactly which services are included in the price.
Ideally, the quotation should clarify:
-
Physician fees.
-
Anesthesia fees.
-
Operating room costs.
-
Hospital accommodation.
-
Examinations and laboratory tests.
-
Medications and medical supplies.
-
Post-procedure follow-up.
-
Any additional services.
The quotation should also clearly identify services that are not included in the stated price so that the patient can estimate the total expected cost of treatment before traveling.
Important Considerations Before Booking Treatment
Choosing a hospital based solely on the name of the hospital group or on accreditation is not sufficient. The appropriate facility also depends on the patient's medical condition and the specialty required.
International patients should confirm that the required specialty is available specifically at Gayrettepe Hospital, identify the physician responsible for the case, determine which examinations will be required, and obtain a clear treatment plan and financial estimate before traveling.
Patients should also clarify the expected length of stay and whether follow-up care will be required in Türkiye or after returning to their home country.
