About radiation therapy

Along with medical and surgical methods, radiation therapy (other name - "radiotherapy") is one of the most popular methods of treating cancer. The essence of the method lies in the use of ionizing radiation emitted by a medical accelerator for the treatment of predominantly malignant tumors.

The method is based on the fact that the pathological focus consists mainly of rapidly dividing cells with a disturbed DNA structure. Ionizing radiation affects the DNA of such cells, stopping the process of their division. Subsequently, the tumor cells die, and the neoplasm itself is gradually destroyed.

Options for the use of radiation therapy:

  • As an independent method of treating an oncological disease at the initial stages of its development, with a low degree of malignancy, as well as in cases where the localization of the tumor does not allow for surgical treatment.
  • After surgery in order to reduce the risk of recurrence both in the area of tumor localization and in nearby organs and tissues.
  • Before treatment with surgical methods to reduce the size of the neoplasm, to simplify the operation or to enable it to be carried out in cases where the tumor was initially recognized as inoperable.
  • To reduce secondary foci of the pathological process (metastases) and their complete destruction.
  • To increase the effectiveness of treatment in combination with drug therapy.
  • To relieve symptoms (palliative care) in the terminal stage.

Types of radiation therapy

Radiation therapy is divided into several types depending on the type of tumor that needs to be treated. It differs both in the type of ionizing radiation generated by the medical device and in the way it is delivered to the target, namely:

  • Remote - the radiation source is located at a certain distance from the object (tumor, metastasis). In this case, a linear accelerator or a close-focus radiotherapy apparatus is used.
  • Contact - the introduction of a source of radiation into the organ affected by the tumor (radionuclide in brachytherapy).

Regardless of the method of radiation supply, the main goal is to destroy the malignancy. The specialists of our medical center use, along with remote therapy, chemoradiotherapy - a combined approach that combines drug treatment with radiation therapy.

We have the most advanced equipment, allowing us to apply the most successful methods of external beam radiation therapy (jointly and separately):

  • 3D conformal (3D-CRT). Specialists create a 3D model of the target (3D planning) and deliver ionizing radiation at different angles in order to fully irradiate it throughout its entire volume with minimal impact on healthy tissues located in the path of the rays, by distributing the intensity of radiation doses between them.
  • Radiation therapy with controlled radiation intensity (IMRT). The technique allows you to change the intensity of the doses delivered for each site, it is well suited for influencing tumors of complex configuration with minimal impact on critical structures located near the focus.
  • With variable radiation volume (RapidArc/VMAT). This technique is one of the most progressive, since it allows you to change not only the intensity of the beam of the delivered dose of radiation, but also the volume of exposure. Thus, a minimal negative effect of the beam hitting healthy structures is achieved.
  • With visual control on the displayed image (IGRT). The key feature is that specialists will control the current position of the neoplasm compared to the previous one. If any changes are detected, the system will calibrate for more accurate beam alignment.
  • Irradiation with an electron beam. The main difference is in the form of radiation: instead of a stream of photons, beams of electrons (negatively charged particles) are directed at the tumor. The method proved to be the most effective in the treatment of tumors located at a shallow depth (basalioma, skin cancer, metastases to the skin and subcutaneous tissue). The flow of electrons, despite its low penetrating ability, is characterized by a high biological potential. This is a gentle technique, since healthy structures located deeper than the neoplasm do not suffer from the negative effects of the rays.
  • Stereotactic hypofractional radiotherapy. The method is applicable for the treatment of neoplasms located in close proximity to critical structures. It consists in delivering high doses of radiation with an increased degree of accuracy. It is indicated for use to affect difficultly localized small tumors, as well as neoplasms located in mobile organs.
  • Xstrahl close focus X-ray therapy.

CHI treatment

The clinic "K+31 West" accepts patients under compulsory medical insurance for radiation, chemoradiotherapy and drug therapy.

The clinic "K+31 West" provides treatment according to compulsory medical insurance in the following areas: radiation therapy, chemoradiotherapy for all nosologies without restrictions in the form 057/y.

Indications for radiotherapy

The decision to conduct radiation therapy or use another method of treatment is made by the attending physician, since each case of cancer is individual. Our center treats various types of benign and malignant tumors:

  • Tumors localized in the head and neck.
  • Neoplasms in the brain and spinal cord, as well as the meninges.
  • Tumors of the esophagus and larynx.
  • Mammary cancer.
  • Tumors located in the pancreas.
  • Prostate cancer.
  • Tumors of the rectum and anal canal.
  • Tumors located in the body and cervix.
  • Skin cancer.
  • Lymphomas with residual formations after chemotherapy treatment.
  • Soft tissue sarcomas.
  • Single metastases, as well as oligometastases from any primary focus.
  • Some other types of cancer.

Although this list is not exhaustive, we do not guarantee radiotherapy in any of the above cases.

Preparatory procedures

The first thing the patient must do is to provide a list of documents, including the following:

  • Referral for radiation therapy (form 057/y) and the conclusion of the medical commission, if the patient plans to undergo treatment at the expense of compulsory medical insurance.
  • Discharge certificate, the results of recent studies (PET/CT, MRI, ultrasound, CT, SPECT/CT, histological and endoscopic results) in the affected area. Most research can be completed within the walls of K+31.
  • Passport, SNILS or CHI policy, if you wish, undergo treatment for CHI funds.

A radiotherapist (radiation therapist) carefully examines all the documents provided by the patient, selects the best option for radiation therapy, advises the patient on the treatment plan, reporting side effects, possible risks and the prognosis of the result. If a treatment technique using a linear accelerator is chosen, the patient must undergo a marking procedure - CT simulation. This is necessary for a detailed study of radiation exposure, the creation of an individual treatment plan, taking into account all the features of the disease. During the procedure, which takes place on a CT scanner, marks will be applied to the patient's skin with a special paint for subsequent radiation calibration during treatment, which will need to be kept for the entire period of therapy. In some cases, special devices are made to recreate the required body position in order to avoid displacement of the radiation exposure area.

How is the treatment going?

Radiation therapy is a course of treatment that includes several sessions ("fractions") conducted at regular intervals. When choosing the duration of the course, various factors are taken into account: the characteristics of the disease, the method of irradiation used, the required dose of radiation, and others. The course can last from 1 day to 1.5 months and include from 1 to 40 sessions. Patients are prohibited from interrupting the course on their own initiative, as this is fraught with the appearance of a stable tumor. In most cases, radiation therapy involves outpatient treatment (no hospitalization), which is well tolerated by patients.

Our clinic has all the amenities for patients with limited mobility: ramps, ergonomic waiting rooms, spacious elevators and toilets for people with disabilities.

Irradiation of the tumor with ionizing radiation is carried out on a specialized installation - a linear accelerator equipped with a built-in multileaf collimator. It allows you to irradiate complex-shaped targets with high accuracy, while not touching healthy nearby tissues and thereby minimizing side effects. For superficially located tumors, a close-focus radiotherapy apparatus is used. On average, one treatment session takes about 10 minutes. The treatment procedure is painless and is accompanied by a slight noise of the equipment, the radiation is invisible to the eyes and is not felt by the patient.

We use advanced equipment manufactured by Varian Medical Systems, in particular Halcyon 2.0 and TrueBeam ST linear accelerators. We also have Xstrahl 200 close-focus X-ray therapy device at our disposal. All these devices and complexes are characterized by high efficiency and safety.

The choice of accelerator is made on an individual basis for each patient, depending on the type, size and location of the formation. Our equipment allows you to effectively treat both small and large tumors without affecting healthy tissues and organs.

Our clinic also has advanced imaging technologies, including the latest MRI and PET/CT units, allowing us to accurately target the tumor as the time between imaging the tumor and starting treatment is greatly reduced. If new symptoms or changes occur during treatment at our clinic, a follow-up MRI or CT can be done quickly, allowing us to adjust our treatment plans in a timely manner.

Side effects and recovery

Despite the highest accuracy of modern installations, healthy tissues are also affected during a session. Ionizing radiation has a devastating effect on the tumor, the decay products of which enter the bloodstream. Although the treatment methods and technologies we use minimize side effects, they do not completely eliminate them. In most cases, moderate side effects are observed, which are only temporary and do not interfere with a full course of therapy. The patient undertakes to promptly inform his attending physician about any negative manifestations.

The main side effects: nausea and vomiting, headaches, diarrhea and intestinal irritation, loss of appetite, general weakness and fatigue, brittle nails and hair loss, changes in blood counts and fever.

Local symptoms depend on the irradiated area:

  • Redness, dry skin, rashes, peeling, swelling at the sites of exposure.
  • Damage to the mucous membrane of organs exposed to radiation.
  • Problems with urination, violation of sexual/reproductive function (with irradiation of the pelvic organs).
  • Difficulty breathing and coughing due to irradiation of the lung, breast and other organs of the chest.

Carefully adhering to the recommendations of the attending physician, the patient will be able to minimize side effects both during the treatment session and after it:

  • Stop smoking, drinking alcohol, hot and spicy food.
  • Maintain a balanced diet, drink plenty of water.
  • Refusal of intensive loads, increased rest and sleep time.
  • Wearing loose clothing made from natural fabrics, caring for areas of the skin exposed to radiation.
  • Thorough oral care using mouthwash solutions, soft toothbrush.
  • Refusal to visit baths and saunas, the use of hard washcloths and scrubs.

At the end of a course of radiation therapy, it is very important to periodically check the results of your treatment by undergoing prescribed follow-up examinations and diagnostic tests.

At the K-31 clinic, I underwent treatment, where a doctor, Anton Vladimirovich, was appointed to me. I want to express my gratitude to him. He is a very responsible, punctual and pleasant young man, which is rare for young people nowadays. Always trying to do what is best and more convenient for the patient !! At the first appointment, he will guide you around the clinic, tell you where to take what, where to undergo treatment (not all doctors do it !!!) He quickly works with the documentation, prepared an extract instantly. I never had to wait for him, always at the workplace. I am very glad that I got such a doctor !!!
