Targeted Radionuclide Therapy: A Breakthrough in Cancer Treatment

Targeted Radionuclide Therapy is one of the most innovative and precise approaches in modern oncology. It combines the principles of nuclear medicine and molecular targeting to deliver radiation directly to cancer cells while minimizing damage to surrounding healthy tissues. This advanced treatment method is transforming how doctors treat complex cancers that do not respond to conventional therapies.

In Turkey, Liv Hospital is among the leading healthcare institutions offering Targeted Radionuclide Therapy. With state-of-the-art facilities, advanced imaging systems, and a multidisciplinary oncology team, Liv Hospital provides patients with personalized and effective cancer treatment options. Understanding how Targeted Radionuclide Therapy works, its benefits, and its applications helps patients make informed decisions about their healthcare journey.

What is Targeted Radionuclide Therapy

This therapy is a form of internal radiation therapy that uses radioactive isotopes attached to molecules specifically designed to target cancer cells. Once injected into the patient’s body, these molecules seek out and bind to cancerous cells. The radioactive component then delivers localized radiation, destroying the malignant cells from within.

This approach differs from traditional external beam radiation therapy, where radiation is delivered from outside the body. Targeted Radionuclide Therapy allows for precise targeting, reducing side effects and improving overall treatment effectiveness.

At Liv Hospital, nuclear medicine specialists use cutting-edge imaging and radiopharmaceutical technology to plan and administer Targeted Radionuclide Therapy safely and effectively.

How Targeted Radionuclide Therapy Works

The effectiveness of Targeted Radionuclide Therapy depends on the ability to combine a radioactive isotope with a targeting molecule, such as an antibody or peptide. These targeting agents recognize specific markers, called receptors or antigens, found on the surface of cancer cells.

Once the radiopharmaceutical is administered intravenously, it travels through the bloodstream and binds to cancer cells. The radioactive isotope then emits radiation, typically in the form of beta or alpha particles, which destroy the tumor cells by damaging their DNA.

Because Targeted Radionuclide Therapy focuses only on affected areas, healthy tissues remain largely unharmed. This makes it especially useful for patients with advanced or metastatic cancers where surgery or chemotherapy may not be suitable.

Liv Hospital’s nuclear medicine department uses advanced PET and SPECT imaging to monitor how the radiopharmaceutical behaves inside the body, ensuring the radiation dose is optimized for maximum safety and effectiveness.

Types of Targeted Radionuclide Therapy

Several types of Targeted Radionuclide Therapy are used depending on the type of cancer and its molecular profile.

Peptide Receptor Radionuclide Therapy (PRRT)

PRRT is one of the most well-known forms of Targeted Radionuclide Therapy, primarily used for treating neuroendocrine tumors. It uses peptides that bind to somatostatin receptors on cancer cells, delivering radiation directly to the tumor.

Radioimmunotherapy

This form of therapy uses antibodies that specifically target tumor antigens. Radioimmunotherapy has been particularly effective in treating certain blood cancers such as lymphoma.

Targeted Alpha Therapy (TAT)

Targeted Alpha Therapy uses alpha-emitting isotopes to deliver high-energy radiation to cancer cells. It is effective for small, localized tumors and shows promising results in resistant cancers.

Bone-Seeking Radionuclide Therapy

This therapy is used to treat cancers that have spread to the bones, such as prostate or breast cancer. The radioactive compounds specifically target bone metastases, relieving pain and controlling tumor growth.

At Liv Hospital, all forms of Targeted Radionuclide Therapy are administered by a team of specialists who tailor the approach to each patient’s specific cancer type and stage.

Benefits of Targeted Radionuclide Therapy

Targeted Radionuclide Therapy offers multiple benefits compared to traditional cancer treatments.

Precision Targeting

Unlike chemotherapy, which affects the entire body, Targeted Radionuclide Therapy focuses radiation on cancer cells, sparing healthy tissues and minimizing side effects.

Effective for Advanced Cancers

Targeted Radionuclide Therapy can reach metastatic tumors throughout the body, providing an option for patients whose cancers have spread beyond the primary site.

Reduced Side Effects

Because the therapy targets cancer cells directly, patients typically experience fewer side effects compared to chemotherapy or external radiation therapy.

Long-Term Control

Studies show that Targeted Radionuclide Therapy can provide durable tumor control and symptom relief, improving quality of life for patients.

Liv Hospital’s oncology specialists combine Targeted Radionuclide Therapy with other advanced treatments, such as immunotherapy or chemotherapy, to achieve optimal outcomes for each patient.

Conditions Treated with Targeted Radionuclide Therapy

Targeted Radionuclide Therapy is used to treat several types of cancers, including:

• Neuroendocrine tumors
• Prostate cancer
• Thyroid cancer
• Lymphoma
• Bone metastases
• Liver metastases

For prostate cancer, for example, radioligand therapy targets prostate-specific membrane antigen (PSMA) receptors. In neuroendocrine tumors, PRRT delivers radiation through somatostatin analogs.

Liv Hospital’s Nuclear Medicine Department has specialized programs for these cancer types, using personalized treatment strategies based on molecular and genetic characteristics.

Procedure for Targeted Radionuclide Therapy

The process of receiving Targeted Radionuclide Therapy involves several stages.

Initial Evaluation

The patient undergoes detailed imaging and laboratory tests to determine eligibility for the therapy. Specialists assess the type of cancer, molecular markers, and overall health status.

Radiopharmaceutical Administration

The radiopharmaceutical agent is injected into the bloodstream. Depending on the type of isotope used, the therapy may require one or multiple sessions spaced several weeks apart.

Monitoring and Safety

After administration, patients are monitored in a specialized room to ensure radiation safety. Imaging tests are performed to track how the drug targets and accumulates in tumors.

Liv Hospital adheres to international safety protocols during all stages of Targeted Radionuclide Therapy, ensuring minimal exposure to medical staff and patients.

Side Effects of Targeted Radionuclide Therapy

Although Targeted Radionuclide Therapy is generally well tolerated, some patients may experience mild side effects, such as:

• Fatigue
• Nausea
• Temporary hair loss
• Low blood cell counts
• Mild pain or swelling at injection sites

Severe side effects are rare, especially when therapy is performed in experienced medical centers like Liv Hospital. Continuous monitoring allows for immediate management of any adverse reactions.
