How is radiation given?
Radiation therapy can be given in 3 ways: 1 External radiation (or external beam radiation): uses a machine that directs high-energy rays from outside the body into the tumor. It’s done during outpatient visits to a hospital or treatment center. It's usually given over many weeks and sometimes will be given twice a day for several weeks. A person receiving external radiation is not radioactive and does not have to follow special safety precautions at home. 2 Internal radiation: Internal radiation is also called brachytherapy. A radioactive source is put inside the body into or near the tumor. With some types of brachytherapy, radiation might be placed and left in the body to work. Sometimes it is placed in the body for a period of time and then removed. This is decided based on the type of cancer. Special safety precautions are needed for this type of radiation for a period of time. But it's important to know if the internal radiation is left in the body, after a while it eventually is no longer radioactive. 3 Systemic radiation: Radioactive drugs given by mouth or put into a vein are used to treat certain types of cancer. These drugs then travel throughout the body. You might have to follow special precautions at home for a period of time after these drugs are given.
Why do doctors recommend radiation therapy?

Can a patient ask for speculation about cancer?
Many patients will not ask for speculation or predictions out of fear of hearing dreaded news—others will. In an effort to avoid this trap, the referring physician’s intentional vagueness is understandable; on the contrary this gives the oncologist the latitude to craft a more positive and factually based discussion. However, the suspicion of cancer having been raised, it’s essential that prompt arrangements be made for seeing that oncologist.
What is PRRT therapy?
Peptide receptor radionuclide therapy (PRRT) PRRT is a molecular targeted therapy used to treat neuroendocrine tumors (NET). Molecular targeted therapies use drugs or other substances to identify and attack cancer cells while reducing harm to healthy tissue.
What is PRRT in IV?
Patients who qualify for PRRT receive a dose of amino acid solution through an IV to protect the kidneys from radiation by reducing how much radiation they absorb. Then, octreotide, a synthetic cell-targeting protein, or peptide, is combined with a small amount of radioactive material, or radionuclide, to create a radiopeptide. When the radiopeptide is injected into a patient’s bloodstream, it binds to protein receptors called somatostatin receptors, located on NET cells, and delivers high doses of radiation to the tumor. Because it’s a systemic treatment, PRRT targets NETs with somatostatin receptors anywhere in the body.
Who may benefit from PRRT?
PRRT is recommended for patients who have somatostatin receptor-positive gastroenteropancreatic NETs, common neuroendocrine tumors that develop in the stomach, rectum, pancreas, and small and large intestine. Typically, NETs aren’t diagnosed until they’ve advanced, which means surgery may not be recommended because it may not remove all the patient’s tumors. Gastroenteropancreatic NETs that cannot be removed with surgery are typically treated with hormone therapy to control symptoms and tumor growth. But in cases when tumors continue to grow despite treatment, the PRRT drug 177-Lu-Dotatate, which combines the manufactured form of somatostatin with radioactive material, may be offered as a second-line treatment. In clinical trials, patients with tumors that were progressing despite first-line treatments and were given 177-Lu-Dotatate lived substantially longer, by almost three years, without cancer progression than patients who were treated with hormone therapy.
What are the potential benefits to patients?
The treatment is designed to slow the progression of disease in gastroenteropancreatic NET patients and to reduce the severity of disease side effects, such as diarrhea.
How long after PRRT is the amino acid solution delivered?
Because small amounts of radiation may remain in the body, patients are generally advised to take certain precautions after treatment, especially for the first one to two days.
Does PRRT cause nausea?
The infusion of amino acids in PRRT helps decrease the amount of radiation the kidneys receive, but it may cause nausea and vomiting, which is typically managed with anti-nausea medication. In rare cases, patients may experience radiation toxicity to the liver and blood system, so patients who have already received heavy treatment to the liver may not be candidates for PRRT because of the toxicity risk. Regulating the dose of radiation may help.
Does PRRT work for NET patients?
Not all gastroenteropancreatic NETs have somatostatin receptors, so PRRT is not an option for all NET patients. Imaging scans, such as Detectnet ™ and NETSPOT, are used to determine whether the appropriate receptors are present.
