This is called the duration of therapy response. This means that one treatment of PRRT can be effective for over 2 years continuing to cause tumors to regress and die. In studies by Dr.
Does PRRT shrink tumors?
PRRT is a treatment option that is highly effective in controlling advanced, metastatic or inoperable, progressive neuroendocrine tumors. PRRT is rarely curative but has been shown to help relieve symptoms, shrink tumors, and slow the progression of the disease.
What are the side effects of PRRT treatment?
The most common side effects of PRRT are nausea, vomiting, belly pain, and temporary hair loss. Nausea is mainly caused by the amino acid infusion. You will be given anti-nausea medicine to lessen this side effect. PRRT can cause low blood counts, which tend to occur after a month or more of treatment.

What causes neuroendocrine carcinoid tumors?
Most carcinoid tumors are caused by sporadic changes (mutations) in oncogenes or tumor suppressor genes. Mutations are called sporadic if they occur after a person is born, rather than having been inherited.
What is DOTA therapy?
Lu DOTA-TATE therapy is a form of peptide receptor radionuclide therapy (PRRT) which targets somatostatin receptors (SSR). In that form of application it is a form of targeted drug delivery.
Can Lutathera shrink tumors?
Lutathera treatment helps make the tumors grow more slowly, shrink, or stop them from growing altogether, and can also help manage the symptoms caused by the tumors.
Is PRRT a radiation?
PRRT delivers high doses of radiation to tumors in the body to destroy or slow their growth and reduce disease side effects.
How often is Lutathera given?
Lutathera treatment is given as 4 separate infusions. The infusions are given 8 weeks apart. You will come to MSK for each of your infusions. Starting after your first Lutathera infusion, you will have blood tests monitored between treatments and for 2 months after your final PRRT.
What is PRRT therapy?
PRRT stands for Peptide Receptor Radionuclide Therapy, an FDA-approved therapy used for systemic treatment of neuroendocrine tumors. Peptide refers to the small molecule for this therapy. The Peptide used (DOTATATE) is very similar to Somatostatin, a hormone which binds to receptors found on neuroendocrine tumors.
How many cycles of PRRT?
Treatment is typically administered in four in-person PRRT cycles. Each cycle is eight weeks apart. Between each treatment, your team will recommend blood tests and repeated imaging, tailored to your health and specific plan. Below is a common timeline for PRRT #1- PRRT#4.
How long does it take for a PRRT to infuse?
You will receive Saline and an Amino Acid Solution through your vein for several hours. The PRRT dose only takes 30 minutes to infuse through your vein, and is not painful. Your clinical team will ensure your comfort throughout your appointment.
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.
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.
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.
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.
What is the night before and/or the morning of the treatment day?

Why do you have to change your clothes after a radiotherapy infusion?
After checking-in at the hospital, the patient is asked to change into a different attire because the treatment/ infusion involves radioactive material and this ensures that the patient’s clothing is free from radiation.
What are the vitals taken before an infusion?
Before the infusion, the nursing staff from the hospital take the patient’s vitals, such as, height, weight, blood pressure, heart rate, respiration rate, temperature etc. These vitals are constantly monitored during the treatment process.
What is PRRT used for?
PRRT is mainly used to treat neuroendocrine tumors. It is being studied in the treatment of other types of cancer that express the somatostatin receptor, including oat cell carcinoma, islet cell carcinoma of the pancreas, pheochromocytoma, and medullary thyroid cancer.
How is PRRT performed?
This varies depending on the center performing the treatment and the radionuclide being used. Patients can have as many as 10 treatments, given anywhere from 6 to 12 weeks apart. The steps of treatment are as follows:
What is PRRT?
PRRT (Peptide Receptor Radionuclide Therapy) is a treatment used for neuroendocrine tumors (NETs). This treatment combines a medication called octreotide (a type of peptide) with a small amount of radioactive material (called a radionuclide). This combination is called a radiopeptide.
How does PRRT work?
Octreotide is a manmade version of somatostatin, which is attracted to these receptors on the NETs. IN PRRT, the octreotide has a radionuclide attached to it. This allows the octreotide to bring the radiation right to the tumor, and not to healthy tissues. This “targeted therapy” limits the radiation exposure to healthy tissue and often has fewer side effects when compared to chemotherapy medications.
What are the side effects of PRRT?
The most common side effects of PRRT are nausea, vomiting, belly pain, and temporary hair loss. Nausea is mainly caused by the amino acid infusion. You will be given anti-nausea medicine to lessen this side effect. PRRT can cause low blood counts, which tend to occur after a month or more of treatment. In rare cases, the treatment can damage the kidneys or liver. Your care team will watch for these problems.

Susan's Story
My name is Susan, and I was diagnosed with carcinoid in February 2002. Following nearly a decade of treatment in the U.S., I decided to seek PRRT treatment with Dr. Baum in 2011. With the help of Dr. Woltering in Kenner, LA, I was accepted into Dr. Baum's PRRT protocol and scheduled for treatment in December 2011.
