Sequential hemibody irradiations refer to a therapeutic technique in radiation oncology where radiation is delivered in a sequential manner to both sides of the body, targeting one half of the body at a time. This specialized treatment method is typically employed to treat widespread cancer metastases or tumors that have spread from their primary site to multiple regions of the body.
The process involves dividing the body into two halves, usually the upper and lower halves or the left and right halves. Radiation is then administered to one half of the body at a time, allowing for careful targeting and improved radiation delivery to the affected areas. Treatment is usually performed in multiple sessions, with a predetermined time interval, to allow for proper healing and recovery between treatments.
Sequential hemibody irradiations aim to improve the effectiveness of radiation therapy, particularly in cases where cancer has metastasized to various distant sites or when tumors are present in large regions of the body. This treatment strategy enables the delivery of higher doses of radiation to the affected areas while minimizing damage to healthy tissues and organs.
This technique is commonly utilized as a palliative treatment option in advanced or metastatic cancers, aiming to alleviate symptoms, control disease progression, and improve overall quality of life. The decision to undergo sequential hemibody irradiations is typically made by a multidisciplinary team, including radiation oncologists, medical oncologists, and other healthcare professionals, based on the individual patient's specific condition, disease stage, and treatment goals.
It is important to note that sequential hemibody irradiations are a specialized radiation therapy approach and should only be performed by trained healthcare professionals in designated radiation oncology centers. Proper monitoring and close follow-up with the treating team is crucial for the effective management and safe implementation of this treatment modality.
