2024: Moscow Department of Health launched an online calculator for doctors to calculate the correct dose of radiation in CT

On July 10, 2024, the department health care Moscow launched a new online calculator for doctors, which will allow you to more accurately calculate the radiation dose during the computed tomography (). CT The chief radiologist of the capital and the director DMS Diagnostic and Telemedicine Center Yuri Vasiliev said that the new tool is already available on the Center's website and is intended for specialists from medical institutions throughout.

Radiation Therapy System That Selects Radiation Dose Based on Biological Tumor Assessment Has Entered the Market

On August 23, 2023, RefleXion Medical announced the launch of the Scintix radiation therapy system with biological control. The complex is intended for the treatment of malignancies in both early and late stages. Read more here.

Radiation therapy in children dramatically increases the risk of diseases of the cardiovascular system

In late June 2023, researchers at the Emory Institute demonstrated for the first time that using the same dose of radiation therapy on substructures hearts as a uniform dose on all heart in children with cancer increases the risk of developing complications on the heart in the future.

For 2023, almost 16 thousand children under the age of 20 are diagnosed with cancer annually in the United States, with about 85% of them surviving for five years. Although cure rates for childhood cancer have improved significantly since 2003, nearly every child who survives cancer develops a life-threatening or fatal late complication after a course of treatment. Heart disease is the most common of these late complications, and radiation therapy is a major risk factor for late heart disease.

Understanding the radiation dose for June 2023 only treats the heart as a single organ and ignores its various substructures such as ventricles, atria, coronary arteries and valves. There is no established guideline for a safe and effective radiation dose for cardiac substructures. Scientists at the Emory Institute emphasize the need to consider radiation doses for heart substructures when planning radiotherapy and in the process of treating surviving patients.

Researchers have shown that heart substructures may be more sensitive to the harmful effects of radiation than when considering the heart as a single organ, a typical approach taken on June 26, 2023 by radiation oncologists.

The study includes 25,481 surviving pediatric cancer patient treated in 1970-1999 as part of the Childhood Cancer Survivor Study. The paper is the largest analysis of its kind and the first to contain a broad, heterogeneous group of children treated for a variety of cancers. It is also the largest study, among both adults and children, analyzing the effects of radiation doses on cardiac substructures in several primary cancer diagnoses.

Scientists at the Emory Institute have suggested that there may be a threshold dose below which irradiation of the whole heart does not significantly increase the risk of coronary disease, arrhythmia or valve disease. However, there does not appear to be a "safe" threshold radiation dose when considering many cardiac substructures. The most sensitive are the right coronary artery and the left ventricle. After 35 years of follow-up, the cumulative incidence of coronary heart disease was 3.9%, and heart failure was 3.8%. Valve disease developed in 1.2% of participants, and arrhythmia was diagnosed in 1.4% of patients.

According to Emory James Bates Institute MD, irradiation of the heart area at a dose of 5-9.9 Gy did not increase the risk of developing any cardiovascular disease. However, irradiation of the right coronary artery area at the same dose from 5-9.9 Gy increased the risk of coronary heart disease by 2.6 times. With irradiation of the left ventricle at the same dose, the likelihood of coronary heart disease increased 2.2 times. The risk of valve disease increased with irradiation of the tricuspid valve area by 5.5 times, and the right ventricle by 8.4 times. According to Bates, radiation methods for 2023, such as intensity-modulated radiation or proton therapy, significantly improve the accuracy of treatment planning. This accuracy allows you to act on specific areas of the heart, and not on the entire organ.

The study was supported by the National Cancer Institute, the Cancer Center Support Grant and the American Lebanese-Syrian Associated Charity.^[1]

2022

Radiotherapy has become available to cancer patients in all regions of Russia

Radiation therapy has become available to cancer patients in all regions of Russia. The head of the Ministry of Health RFMikhail Murashko said this at the end of November 2022 at a meeting with President Vladimir Putin.

In fact, photon therapy and radiotherapy in all subjects have become available today. This, of course, is such a breakthrough solution, and for the third year we have already made available help - proton therapy. This is a new format of treatment antitumor, antitumor therapy. Therefore, almost the entire spectrum today is the most modern available, "the minister said.

Radiotherapy has become available to cancer patients in the Russian Federation

According to Murashko, by the end of November 2022, 57 billion rubles are planned for six new oncological dispensaries under the oncology program in the federal project. In total, 449 outpatient oncological care centers have been opened in the country.

Within the framework of the federal project, the re-equipment of federal and regional medical organizations is being carried out, where patients with cancer are treated. Including, at the disposal of doctors appeared radiation installations of the latest generation for radiotherapy, they allow the use of the most modern treatment methods. For 2019-2020, within the framework of the federal project, 72 remote radiation therapy units were put into operation in regional medical organizations..

For Russian citizens, radiation therapy is carried out free of charge, since this method of treatment is included in the programs of compulsory medical insurance and high-tech medical care. Treatment can be carried out on the basis of regional cancer centers, in federal centers and in private clinics that work in the compulsory medical insurance system.

Radiation therapy (radiotherapy) is a method of local exposure. At all stages except 4, when there are distant metastases, radiotherapy is used with a radical goal: to destroy all tumor cells and reduce the risk of recurrence to a minimum.^[2]

Radiotherapy after breast surgery does not improve overall survival

In mid-November 2022, radiotherapy after breast surgery for early breast cancer significantly reduces the risk of recurrence of the disease, however, this advantage did not lead to an improvement in overall survival for 30 years. This is stated in a report by scientists from the Scottish Bureau of Cancer Research at the University of Edinburgh. Read more here.

2020: Russian doctors began treating cancer by tereotactic radiation therapy

At the end of July 2020, it became known about a new method of treating cancer, which Russian doctors began to use.
