One of the most effective and safe methods of cancer treatment is radiation therapy — the tumor is exposed to pinpoint ionizing radiation rays and thus destroyed. The most modern and effective type of radiation therapy is tomotherapy. Its peculiarity lies in the spiral movement of the impacting rays and the formation of a fan beam of radiation. This allows the treatment of tumors that have spread over a large area in the least number of sessions.
The question that concerns most patients is at what stages tomotherapy is effective. The method destroys tumors of different sizes with the same accuracy and can be used to affect several foci at once (i.e., the primary tumor and metastases), therefore it shows good results at different stages.
Features and benefits of tomotherapy
Tomotherapy abroad has two features that determine its superiority over other methods of radiation therapy:
- the combination of the features of all previous generations of radiation therapy devices in the latest equipment: gamma knives and cyber knives, intensity monitoring and video guidance devices, etc;
- unprecedented accuracy of exposure to rays. Neighboring tissues are not exposed to radiation, which is concentrated only on the site of the neoplasm. Therefore, tomotherapy abroad is one of the safest methods of cancer treatment.
Tomotherapy treatment
The tomotherapy procedure includes several necessary steps to ensure maximum treatment effectiveness:
- preliminary examination. It is necessary to determine the optimal treatment strategy that takes into account each specific case. The patient is prescribed a computed tomography (CT) scan to obtain an accurate image of the tumor and its surrounding organs. On the basis of these data, foreign experts determine the direction and intensity of the influencing rays, which are then introduced into the latest tomotherapy equipment.;
- placement of the patient in the tomotherapy unit. In order to eliminate the slightest error in the radiation distribution, the patient undergoes another CT scan immediately before therapy. The new results are compared with the results of the preliminary CT scan, and, if necessary, the data on the direction and intensity of the rays are adjusted. Accuracy and safety are the priority of tomotherapy abroad;
- radiation exposure. The radiation source slowly rotates around the patient, irradiating the tumor in a spiral and thereby capturing it in full. The horizontal movements of the bed on which the patient lies during therapy are carried out synchronously with the source. Thanks to this technique, foreign specialists are able to remove even overgrown tumors in one session, which with another method would need to be irradiated in several sessions. The intensity, shape and area of the irradiation is continuously monitored by a computer.
After the tomotherapy, another CT procedure is performed to evaluate the results of the treatment.
Postoperative period
Tomotherapy abroad does not lead to any side effects, so it is enough for the patient to visit his doctor regularly. Experienced foreign specialists consult their patients in detail and closely monitor their condition. Full recovery takes place within a few days.
