This publication provides an overview of the current state of the art in the use of stereotactic radiation therapy (SBRT) for patients with head and neck tumors. We have analyzed current trends, and also presented the features of radiobiology and the basic principles of radiation treatment. Special attention is paid to indications for SBRT, fractionation schemes and radiation planning. The use of SBRT for primary head and neck tumors, including boost, as well as relapses treatment are described. The results of the implementation of SBRT by various authors both as an independent option and in combination with drug therapy are presented. The efficacy and tolerance of radiation is described in a summary form with clarifying comments. The radiation therapy toxicity profile is detailed, including the main risk factors of postradiation complications.
An experience of successful treatment of giant lymphocele and related secondary complications, such as signs of hydronephrosis of both kidneys of a patient after Wertheim surgery in case of cervical disease before radiotherapy is described. A complex of ultrasound studies using 3 types of echographic picture of the lymphocele was applied, which made it possible to determine the rational management of the patient using the technique of invasive sonography. Ultrasound examination, on the 17th day after the operation, revealed lymphocele in the iliac regions (1450 ml on the right, 1290 ml on the left) and signs of hydronephrosis of both kidneys. Drains under the control of sonography in both the lymphatic cavity were set up. Signs of hydronephrosis of both kidneys ceased to be located on the 2nd day after the installation of drains. Drains were removed after 13 days. During further ultrasound examinations of the patient, the lymphocele and signs of hydronephrosis were not rendered. Ultrasound examinations were performed on the 3rd, 7th, 12th, 21st, 35th, 62nd, 145th day after drains were removed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
