Stomach cancer

Stomach cancer is an epithelial tumour of the stomach lining. Currently around 19,000 new cases per year are recorded. A distinction is made especially between the early carcinoma, which affects only the mucosa, and the advanced cancer that infiltrates the muscle layers.

Pre-existing conditions in the stomach (such as chronic gastritis or a resection of the stomach part) are among the known risk factors, but also tobacco smoke or nitrosamines in food (found in meat and sausages) as well as the accumulation of the bacterium Helicobacter pylori of the stomach, can promote the disease. A familial predisposition and the nationality (possibly due to diet) can play a role.

With gastric cancer, the patient does not show any symptoms in the early stages (apart from a ‘sensitive stomach’). However in the later stages, symptoms such as weight loss, fatigue, pain, nausea, and possible aversion to certain foods (frequently meat and sausage), begin to show.

Chronic blood loss (tarry stools) can lead to anaemia with corresponding symptoms. Also blood sedimentation can be a non-specific indication, as well as swollen lymph nodes, and in later stages, metastases.

A diagnostic gastroscopy with tissue removal is the first test undertaken. Endosonography, abdominal ultrasonography, computed tomography of the abdomen, a bone scan and chest radiograph are also are used to determine the extent of the tumour and any metastases.

Recommended therapies for the treatment of stomach cancer:

Photodynamic therapy

At the Hyperthermia Centre Hannover, we recommend photodynamic therapy (PDT) to our patients with gastric cancer, in which targeted diseased cells are destroyed by light. In the process, a light-activatable substance (a so-called photosensitizer - here: Chlorin) is injected. This triggers a chemical reaction in combination with light of a specific wavelength in the diseased cells, which leads to cell death. The surrounding healthy tissue is spared.

Whole body Hyperthermia

For patients with stomach cancer the healing effect of whole-body hyperthermia is that we can very quickly bring the body to high temperatures (up 40.5 °). This fast and high heating activates not only the immune system, but many degenerate cells of the stomach lining are destroyed by the fast floods of heat. In addition to the damage or removal of the cancer cells, the whole-body hyperthermia stimulates the immune system significantly without impacting the rest of the body. It triggers an immune cascade that activates and multiplies the white blood cells.

Locoregional Hyperthermia

The regional effective hyperthermia is also advisable for stomach cancer: during this treatment the affected region is quickly heated to high temperatures (40 up to 44 ° C). This heat activates the immune system. Many degenerated cells of stomach lining will be harmed or destroyed. In our day clinic at the Hyperthermia Centre Hannover we offer the partial body hyperthermia depending on the diagnosis, in which only damaged or degenerated tissue is overheated, which guarantees very gentle treatment to our patients.

IPT - Low Dose Chemotherapy

Patients with stomach cancer can be successfully treated at the Hyperthermia Centre Hanover with IPT, which uses the sugar blood lowering hormone to inject drugs more effectively in the tumour cells. Because the degenerate cells of stomach lining have a higher basal metabolic rate than normal cells, they attempt to absorb sugar more quickly after a period of low blood sugar. The mechanism is via so-called receptors. Because tumour cells  in the stomach lining have in general more receptors than normal cells, chemotherapy can therefore impact the malignant cells more effectively. As a result the dosage of conventional chemotherapy protocols can be reduced, and thus the side effects can also be significantly lowered.


The nutritional therapy of Dr. Gerson aims at detoxifying the body with the simultaneous addition of many fresh nutrients, which is particularly useful for patients with stomach cancer. The therapy includes special juices, fresh and elaborately prepared and taken throughout the day, along with essentially high-quality fresh fruits and vegetables. These are carefully prepared to contain their healing powers, partly as fresh food, in special soups, or gently cooked and steamed. The Gerson therapy is low in sodium, protein and fat.

Infusions with high-dose Vitamin C

At the Hyperthermia Centre Hannover we treat patients with stomach cancer successfully with high-doses of vitamin C. The so-called Ascorbic acid is the best known vitamin, – and the most important antioxidant, i.e. it intercepts harmful free radicals in the body and makes them harmless – and in this way prevents degeneration in the cells. Vitamin C is also essential for the immune system and various restructuring processes in the body. When vitamin C is given in a high- dose, the treatment of stomach cancer can be positively affected.


Patients with stomach cancer can benefit from the healing-effects of an oncolytic virotherapy. A virotherapy uses viruses to destroy cancer cells with very few side-effects. The Virotherapy itself consists of several injections according to a predetermined Virotherapy treatment protocol. Dr. Mohamed Ali Zayen is a certified specialist of Virotherapy RIGVIR®. Our Virotherapy protocol is an outpatient treatment and provided to you according to an individual treatment plan. The interval of RIGVIR® injection is different from one protocol to another.
