What is stereotactic radiosurgery?
Stereotactic radiosurgery (SRS) is a radiation treatment that uses focused delivery of radiation in high doses to precise locations in the body. It is used to treat certain tumors and other abnormalities of the brain, spine, neck, lungs, liver, etc.
Swedish neurosurgeons first developed SRS in the 1950s to treat small tumors located deep in the brain with minimal damage to the nearby healthy tissue. Now, doctors use it to treat any part of the body where tumors are hard to reach or close to vital organs. SRS may also be called “stereotactic body radiotherapy” when performed on areas other than the brain and spine.
How does stereotactic radiosurgery work?
SRS is noninvasive and not a surgical operation in the traditional sense. It delivers high doses of radiation precisely targeted at the tumor. It damages the DNA of the tumor cells and stops them from reproducing, which makes the tumors gradually shrink.
While SRS on the brain or spine is usually performed in a single session, treatment of other areas in the body may take three to five sessions.
What are the types of stereotactic radiosurgery?
There are three different techniques of SRS. The radiation is delivered using one of the following:
- a gamma knife unit
- a linear accelerator
- proton beams
Why is stereotactic radiosurgery performed?
SRS is a preferred method of treatment for tumors in hard-to-reach places and for certain rare conditions, because it is a minimally invasive and precisely focused treatment. Following are some of the conditions for which SRS is performed:
Brain tumors such as
- acoustic neuroma
- low-grade astrocytoma
- pineal tumor
- malignant glioma
Other benign growths and cancers such as
How is stereotactic radiosurgery performed?
SRS is usually an outpatient procedure, but it might take a whole day though the actual procedure may take an hour or more.
Before the SRS a patient needs to
refrain from eating and drinking starting at 12 a.m. on the day of the treatment,
check with the doctor if their regular medications may be taken, and
inform the doctor if they have any implanted devices.
SRS involves a lot of CT and MRI imaging to precisely locate the tumor. A specialized team of doctors work together to perform the SRS, including a radiation oncologist and a neurosurgeon.
SRS is mostly done without general anesthesia except in children.
An intravenous (IV) line might be attached to the patient to keep them hydrated with fluids.
For a brain-related SRS a headframe is attached to the patient’s head with 4 pins to keep it immobile.
A soft mask may be placed on the face in case doctors need to protect it from the radiation.
The patient must lie still during the procedure, but will be able to talk to the attending doctors through the microphone.
The doctors monitor the procedure on imaging screens to deliver the radiation to the precise location.
The patient will be under observation for up to two hours after the procedure, sometimes longer.

What are the side effects of stereotactic radiosurgery?
Side effects of SRS include:
The following rare complications may occur:
Does stereotactic radiosurgery work?
SRS is an effective noninvasive treatment for certain tumors and conditions. This minimizes the risks and recovery time, and damage to healthy tissue. The efficacy of SRS also depends on the condition being treated and the stage of disease.

Brain and Spinal Cord Tumors in Adults (Symptoms, Signs, Causes, Treatment Options, Life Expectancy)Brain and spinal tumor are diseases in which cancer (malignant) cells begin to grow in the tissues of the brain. Tumors that start in the brain are called primary brain tumors. Tumors that start in the brain and spread to other organs are called primary brain tumors. Symptoms may include headaches, personality changes, dizziness, and trouble walking. Treatment depends upon the type and grade of tumor.
Bladder Cancer SlidesBladder cancer occurs when cancerous cells, often from the lining of the bladder, begin to multiply. Find more information about bladder cancer, the stages of bladder cancer, and available treatment options.
Brain CancerCancers that form from brain tissue are called primary brain tumors. Brain tumors may be malignant (brain cancer) or benign. Certain risk factors, such as working in an oil refinery, as a chemist, or embalmer, increase the likelihood of developing brain cancer. Symptoms include headaches, weakness, seizures, difficulty walking, blurry vision, nausea,vomiting, and changes in speech, memory, or personality. Treatment may involve surgery, radiation therapy, or chemotherapy.

Learn the brain cancer survival rate, treatment options including chemotherapy, and the different brain tumor grades. Find out how the right treatment plan can fight cancerous brain tissue.
Brain Tumor: Warning Symptoms, Types, Causes, Treatments, and CureA brain tumor can be either non-cancerous (benign) or cancerous (malignant), primary, or secondary. Common symptoms of a primary brain tumor are headaches, seizures, memory problems, personality changes, and nausea and vomiting. Causes and risk factors include age, gender, family history, and exposure to chemicals. Treatment is depends upon the tumor type, grade, and location.

Screening Tests for CancerCancer detection are methods used to find cancer in persons who may or may not have symptoms. Symptoms of cancer are abnormal sensations or conditions that persons can notice that are a result of the cancer. It is important to your doctor for regular checkups and not wait for problems to occur.

Carcinoid Syndrome (Tumor)A carcinoid tumor is a tumor that develops from enterochromaffin cells. The important characteristic of carcinoid tumors that sets them apart from other gastrointestinal tract tumors, is their potential to cause the carcinoid syndrome. Local symptoms may include abdominal pain, intestinal bleeding, flushing., gastrointestinal bleeding, and diarrhea. Often, symptoms of the carcinoid syndrome can be more devastating than the local symptoms. There are many options for the treatment of carcinoid tumors and carcinoid syndrome.

Prolactinoma (Pituitary Tumor)Prolactinoma is an adenoma (benign tumor) of the pituitary gland. Causes of many prolactinomas are unknown. Symptoms in women include:

Radiation Therapy for Breast CancerRadiation refers to high-energy rays that are directed at the breast to kill or slow the growth of cancer cells. Radiation reduces the risk of local cancer recurrence in the breast. Potential side effects include skin redness, swelling, peeling, and fatigue. It is necessary to undergo follow-up exams and diagnostic X-rays after completing radiation therapy for breast cancer.
Tumor GradeTumor grade is a system used to classify cancer cells in how likely the tumor is to grow and how abnormal they look under a microscope. Tumor grade is not the same as tumor stage. A biopsy is taken to determine if the tumor is benign (non cancerous) or malignant (cancerous).
Uterine Fibroids (Benign Tumors of the Uterus)Uterine fibroids are benign (non-cancerous) tumors in the womb (uterus). Most uterine fibroids do not cause symptoms; however, if the fibroid is large enough and in the right location, it may cause symptoms of pelvic pain, abnormal vaginal bleeding, and pressure on the bladder or rectum. Uterine fibroids that remain small and do not grow usually do not need treatment; however, surgery to remove the fibroid may be necessary. Uterine fibroids do not cause cancer; however, there is a rare, fast-growing cancerous called leiomyosarcoma.
What Is Intraoperative Neurophysiological Monitoring?Intraoperative neurophysiological monitoring is the continuous evaluation of a patient’s nervous system during surgery, especially procedures involving the brain and spinal cord. Electrical and electromagnetic sensors connected to the patient via adhesive electrodes or needles transmit information from the nervous system that can be monitored on a computer screen.
