Intraoperative electron radiation therapy

From WikiMD's Wellnesspedia

Intraoperative electron radiation therapy (IOERT) is a specialized form of radiation therapy that is administered during surgery. This technique allows for a high dose of radiation to be delivered directly to the tumor site, minimizing exposure to surrounding healthy tissues. IOERT is often used in conjunction with other treatments, such as surgery, chemotherapy, and external beam radiation therapy.

History[edit | edit source]

The concept of IOERT was first introduced in the 1960s, with the aim of improving local control of cancer and reducing the risk of recurrence. The technique has evolved over the years, with advancements in technology and understanding of cancer biology.

Procedure[edit | edit source]

During IOERT, the patient is placed under general anesthesia. The surgeon then removes as much of the tumor as possible. A specialized radiation machine, known as a linear accelerator, is used to deliver a concentrated dose of radiation directly to the tumor site. The radiation is delivered in the form of electrons, which can penetrate the tissue to a specific depth, minimizing damage to surrounding tissues.

Indications[edit | edit source]

IOERT is used in the treatment of various types of cancer, including breast cancer, colorectal cancer, pancreatic cancer, and sarcoma. It is particularly useful in situations where the tumor is located close to critical structures, such as the spinal cord or major blood vessels.

Benefits and Risks[edit | edit source]

The main benefit of IOERT is that it allows for a high dose of radiation to be delivered directly to the tumor site, potentially improving local control and survival rates. However, like all forms of radiation therapy, IOERT carries risks, including damage to surrounding healthy tissues and potential side effects such as fatigue, skin changes, and nausea.

Future Directions[edit | edit source]

Research is ongoing to further refine the technique of IOERT and to determine its optimal role in the treatment of various types of cancer. This includes studies to evaluate the effectiveness of IOERT in combination with other treatments, and to identify the patients who are most likely to benefit from this approach.
