SBRT vs Surgery: How Doctors Compare Them

This page is for people weighing stereotactic body radiation therapy (SBRT) against surgery. Both may come up in cancer care. One is not simply better than the other. Their goals, evidence, side effects, and backup plans all differ.

SBRT delivers a high dose of radiation very precisely, in a small number of visits. Most SBRT plans use up to five treatments, rather than the daily sessions over weeks that standard radiation uses.

NCI says it is used for small, isolated tumors outside the brain and spinal cord, often in the liver or lung. It may be an option when surgery is not possible because of age, health problems or other reasons.

Ask what problem the option is meant to solve. It may be removing the cancer, lowering the chance it comes back, protecting function, avoiding an operation, or easing symptoms.

Surgery may be preferred when taking the tumor out gives the best chance of control. It also helps when tissue is needed to confirm the diagnosis, or when symptoms need fixing that radiation cannot reach. Surgery works best for solid tumors held in one area.

The best comparison is personal. Doctors may weigh the tumor, test results, past treatment, other health problems, recovery needs, help at home, travel distance, and what you want.

Several things shape the comparison. They include the size and location of the tumor, which organs sit nearby, how well your lungs and heart work, recovery time, whether tissue is needed, and how strong the evidence is for your cancer type.

Recovery differs too. SBRT usually means a handful of visits with no operation. NCI says recovery from surgery can take 1 day or many weeks, and some people stay in the hospital. Surgery does remove the tumor and gives tissue to examine.

Ask the same questions about both options. What is the expected benefit? Which side effects are common? Which ones may be permanent? How soon would treatment start? How long is recovery? What follow-up comes after?

• What would your specialty's treatment try to accomplish for me?
• What would make you recommend the other option instead?
• What outcomes matter most for someone like me?
• What side effects would change daily life?
• Would treatment order matter?
• Is there a clinical trial comparing these approaches?

Consider another opinion when:

• The choice affects breathing, bladder, bowel, sexual function, speech, swallowing, movement, or work.
• Another center offers different technology.
• One team says there is only one reasonable option and you are not sure why.

• Call 911 or go to an emergency department if you have chest pain, sudden or severe shortness of breath, coughing up blood, heavy bleeding, or new pain and swelling in one leg. Go straight in as well for a fever with shaking chills, a racing pulse, confusion, or skin that is mottled and cold. Do not drive yourself.
• If you are also having chemotherapy, according to CDC, fever during chemotherapy is a medical emergency. Use 100.4°F (38°C) or higher. Call your care team immediately, day or night. If you cannot reach them quickly, go to an emergency department and tell them right away that you are having chemotherapy.
• Call your care team the same day if you have a temperature of 100.4°F (38°C) or higher and are not having chemotherapy, or you have new redness, swelling, or drainage from a surgical wound, pain that your medicine no longer controls, or you cannot keep food and fluids down.
• Call your care team within a day or two if you have a new or worsening cough, breathlessness with everyday activity, or worsening fatigue.

Report new symptoms as they happen rather than saving them for the next scan.
