- At the clinic's price without markups
- with full doctor support
Stomach cancer is a complex disease, but in recent years the treatment possibilities have improved significantly. A properly chosen strategy, especially in early and operable stages, provides a real chance for a good outcome.
In Turkey, according to a large study (683 patients), the average age of patients is 57.4 years, and 85.6% of patients undergo surgical treatment. Although many cases are diagnosed at stages III–IV, with a comprehensive approach (perioperative therapy + robotic surgery), outcomes in leading clinics are noticeably better than average indicators (Journal of Clinical Oncology).
Turkey has become one of the strongest destinations in this field. International protocols are actively followed here, the da Vinci robot is used for D2 gastrectomies, FLOT perioperative chemotherapy, immunotherapy, and targeted drugs are widely applied. At the same time, prices remain significantly lower than in Europe or Israel, while the equipment and physicians’ expertise are at a high level.
At Experts Medical, we have been helping patients with stomach cancer for many years. We have reviewed dozens of centers, studied specialists, their publications, and real treatment outcomes. You no longer need to spend weeks searching and comparing — we have already done everything for you.

- Need the highest technical level + MDT → Memorial Şişli or Acibadem.
How stomach cancer treatment is performed in Turkey
Stomach cancer treatment in Turkey is based on current international ESMO and NCCN protocols. The approach is always individualized and determined at a multidisciplinary tumor board. Doctors take into account the stage, molecular profile (HER2, MSI-H, PD-L1, CLDN18.2), the patient’s general condition, and the possibility of preserving quality of life.
| Treatment Method | When It Is Used | Advantages in Turkey | Approximate Cost (2026) |
|---|---|---|---|
| Surgical treatment (D2 gastrectomy) | Localized and locally advanced cancer | da Vinci robot, high-precision lymph node dissection | $15,000 – $28,000 |
| Perioperative chemotherapy (FLOT) | Before and after surgery (stages II–III) | MATTERHORN standard, good tolerability | $5,000 – $8,000 per course |
| Immunotherapy (nivolumab, pembrolizumab) | Metastatic cancer, MSI-H, high PD-L1 | Combinations with chemotherapy, long-lasting effect | $2,000 – $5,000 per course |
| Targeted therapy (trastuzumab, T-DXd) | HER2-positive cancer | Precise combinations based on NGS results | $5,000 – $8,000 per course |
| Adjuvant radiation therapy | After surgery in cases with a high risk of recurrence | Modern linear accelerators (TrueBeam) | $6,000 – $12,000 |
Treatment usually begins with thorough diagnostics (endoscopy with biopsy, PET-CT, NGS). In operable forms, perioperative therapy is often used to shrink the tumor before surgery and reduce the risk of recurrence. In metastatic cases, the focus is placed on systemic therapy and symptom control.
Turkish clinics offer the full treatment cycle in one place — from molecular diagnostics to rehabilitation, with convenient support services for international patients.
Advantages of stomach cancer treatment in Turkey
Turkey offers one of the best balances between cost and quality in stomach cancer treatment. The most modern protocols (ESMO/NCCN) are used here, including perioperative FLOT therapy, immunotherapy, and targeted drugs, which are not available in many countries.
Key advantages:
- Significantly lower cost (2–3 times cheaper than in Europe or Israel) with a comparable level of care
- High volume of D2 gastrectomy procedures using the da Vinci robot
- Fast access to molecular testing (NGS) and new medications
- Full treatment cycle in one place + Russian-speaking support
- A high percentage of patients receiving radical surgical treatment
Recovery after treatment
After stomach surgery (especially robot-assisted procedures), patients usually stay in the clinic for 5–8 days. Recovery takes place under the supervision of dietitians and rehabilitation specialists: nutrition is gradually introduced, patients are taught the correct eating regimen, and they are helped to adapt to the new stomach volume.
During chemotherapy or immunotherapy, most procedures are performed on an outpatient basis. Patients note good tolerability thanks to modern regimens and supportive therapy. Full return to normal life after comprehensive treatment takes from 4 to 8 weeks. Many international patients complete part of their rehabilitation at home while staying in contact with Turkish doctors.
Survival statistics and treatment effectiveness for stomach cancer in Turkey
Overall survival rates
According to clinical studies, the outcomes of stomach cancer treatment in Turkey are generally comparable to those of European centers. In one recent analysis, the five-year survival rate was approximately 51.7%, reflecting improvements in treatment and diagnostic approaches (Turkish Journal of Medical Sciences, 2024).
Dependence on stage
The difference is especially noticeable here. With early diagnosis (stage I), survival rates reach up to 80–85%, while at later stages the indicators decline (Journal of Cancer Research and Therapeutics, 2013).
The role of combined treatment
Modern treatment is rarely limited to surgery alone. As a rule, a combination of surgery, chemotherapy, and, if necessary, radiation therapy is used.
Studies show that this comprehensive approach provides more stable outcomes and reduces the risk of recurrence.
Important note
Statistics provide a general understanding but do not determine an individual prognosis. Even with the same diagnosis, outcomes can differ greatly.
The decisive factors remain the stage of the disease, the possibility of radical surgery, and the experience of the team managing the patient.
How we at Experts Medical help organize treatment abroad
When patients contact us with a stomach cancer diagnosis, we do not start by offering clinics. First, we analyze the situation: review the documents, clarify the details, and sometimes request additional data. At Experts Medical, it is important for us to understand not only the diagnosis but also the context — the stage, overall condition, and previous treatment attempts.
Next, we involve the medical board. Together with профильными specialists, we select a doctor and clinic with real experience in exactly such cases. This is not a list “to choose from,” but a specific solution for a specific patient.
After that, we take over the entire organizational process. The patient does not need to deal with logistics or search for contacts — we structure the process so that it is clear and manageable. And we stay in touch at every stage.
What exactly we do
- analyze medical documents and help clarify the diagnosis
- select a doctor and clinic for the specific situation
- coordinate the treatment plan and timelines
- organize travel, accommodation, transfer, and interpreter services
- provide support during and after treatment
- manage organizational and financial matters
We do not sell treatment and do not add markups. Payment is made directly to the clinic. Our task is to ensure that the patient receives treatment from the right doctor and does not waste energy on organizational details.
Conclusion
Stomach cancer treatment in Turkey is currently at a very high level. Thanks to experienced specialists, modern protocols (FLOT, immunotherapy, targeted therapy), robot-assisted surgery, and rapid molecular profiling, patients receive outcomes comparable to leading centers in Europe and the USA, but at a significantly more affordable cost and in comfortable conditions.
The choice of clinic and doctor is especially important here: the molecular status of the tumor and the stage of the disease determine which specialist and approach will be optimal. The right decision can significantly influence both prognosis and quality of life.
At Experts Medical, we have already analyzed all key centers and specialists, studied their experience, publications, and real patient outcomes. You do not need to spend time and effort on long searches — we have already done it for you and are ready to help select the optimal option specifically for your clinical situation.
