Clinical Department of Radiation Therapy

  • Head of the Department Dr. Zanda Liepa

Radiation therapy (radiation oncology) is one of three basic methods of treatment in oncology (along with surgery and chemotherapy), yet it may be used in case of non-oncologic disease as well (in case of certain indications). External radiation (distance radiation therapy) and internal radiation therapy (brachytherapy) are used to treat patients.

In oncology, radiation therapy may also be applied both as the only radical non-invasive method of treatment in case of early stages of cancer (pancreatic, lung, and liver cancer) and as a part of the combined treatment (breast, colorectal, ENT organs, lungs, central nervous system, urological, and other tumours), as well as palliative and symptomatic treatment for patients with advanced stage of cancer.

Three-dimensional conformal radiation therapy. The method of radiation therapy, when the dose of ionising radiation is determined individually for every patient, based on the computed tomography data about the location of the tumour and internal organs. Advantages: significantly reduces radiation therapy complications, improves the quality of patient’s life. Introduced in Latvia in 2001.

Intensity-modulated radiation therapy. The method of three-dimensional conformal radiation therapy which uses the areas of radiation therapy with modulated photon beams to create the dose of ionising radiation that is individually adjusted to the shape of the tumour. Advantages: allows ensuring the greater dose of radiation delivered to the pathological focus and reduces the dose delivered to the adjacent tissues. Introduced in clinical practice of Latvia in 2003.

Image-guided radiation therapy. By using the diagnostic X-ray equipment integrated into the accelerator, this method ensures precise positioning of the patient’s body during the treatment. Advantages: allows determining the precise location of the tumour and targets the ionising radiation directly into it. Introduced in 2009.

Breathing-synchronized radiation therapy. By following the movement of organs during the breathing, this method allows performing irradiation only during the pre-set phase of the breathing cycle. Advantages: allows reducing the dose of radiation, while evenly covering the tumour by the dose of ionising radiation. Introduced in 2006.

Stereotactic radiation therapy (radiosurgery). By using several technical possibilities, this method delivers extremely high dose of ionising radiation directly into the tumour. Advantages: allows treating small-sized tumours without radiation therapy complications in healthy organs. Introduced in 2009. The linear accelerator Novalis TX is the only medical equipment in the Baltic States that is used for stereotactic therapy and stereotactic radiosurgery. The Clinic of Therapeutic Radiology and Medical Physics is the only place where radio-surgical and stereotactic hyperfractionated treatment may be carried out.

Modern radiation therapy requires a preparation process with several stages:

It starts with the selection and creation of means of patient’s individual immobilization. The planning of the three-dimensional radiation therapy is carried out for all the patients, by using the specialized computer-assisted topometry data on every patient. The clinic ensures a possibility of performing mutual spatial registration of digital images of different diagnostic methods to obtain precise information on the spread of the tumour.

During the three-dimensional reconstruction, the amount of radiation is determined and healthy adjacent risk organs are identified for every patient, in order to determine the distribution of the dose of ionising radiation in the tumour during the planning process and protect healthy organs to the extent possible.

Plan analysis, plan verification under X-ray radiology control, and dosimetry are the last stages before the course of radiation therapy is commenced.

The Clinical Department of Radiation Therapy consists of two in-patient departments (on the 7th and 8th floor of the In-patient Department “Latvian Oncology Centre”) and the department of out-patient admission (on the 1st floor of the In-patient Department “Latvian Oncology Centre”).
