Lu177 PRRT For Neuroendocrine Tumors (Nets)

 Nuclear Medicine, as a treatment protocol for Neuroendocrine Tumors (NETs) has been used in many countries across the globe for many a years.

PRRT or Peptide Receptor Radionuclide Therapy is a type of Nuclear Medicine Therapy in which a cell-targeting protein or peptide is combined with a small amount of radioactive material that created a special type of radiopharmaceutical known as a Radiopeptide. This radiopeptide is injected into a Neuroendocrine Tumor patient’s bloodstream.

Unlike healthy cells, the neuroendocrine tumor cells or NET cells have proteins on their cell surface. These proteins, also known as receptors, bind themselves to hormones, such as somatostatin. Peptide Receptor Radionuclide Therapy or PRRT with lutetium 177 dotatate or Lu177 targets these receptors with radiopeptides and deliver a high dose of radiation to the tumor cells.

How PRRT for NET works? – Method of Action

1.        A peptide i.e. a group of amino acids is created that can bind to the receptors on the tumor cell’s surface.

2.      This peptide is then paired with a radioactive atom using a chelator (a bonding agent).

3.      This combination of the peptide and the radioactive material creates a radiopeptide.

4.      This radiopeptide is injected into a Neurodendocrine Tumor (NET) patient’s bloodstream.

5.      The radiopeptide finds the NET cancer cell’s somatostatin receptors and binds itself to them.

6.      The radiopeptide emits radiation that kills the NET cancer cell.

Tare Vs Tace For Hepatocellular Carcinoma and Net Patients

  The incidence of Hepatocellular Carcinoma or HCC has been increasing over the past several years and several studies have projected that the incidence of HCC will continue to rise in the coming years. Transarterial Chemoembolisation or TACE has been the initial treatment modality for HCC and has a huge body of evidence from several studies and clinical trials. Therefore, for long TACE has been a preferred treatment algorithm for unresectable HCC. However, as the experience of  Transarterial Radioembolisation or TARE  has evolved, it is playing an increasingly important role in the treatment of unrespectable HCC. Studies and trials have shown that TARE has many potential advantages over TACE and there is now substantial evidence to favor TARE over TACE. The many potential advantages of TARE when compared with TACE are as below: · Several studies have shown a statistically significant overall survival advantage with TARE as compared to TACE. · TARE has better health-related quality-of-

Everything You Need To Know About Alpha PSMA Therapy

According to the  World Cancer Research Fund , Prostate Cancer is not only one of the most common malignancy in men but also one of the most commonly occurring cancer overall. Prostate Cancer is also the fifth leading cause of death from cancer in men. Disease progression and metastatic spread signifies the beginning of a lethal form of the disease – metastatic castration resistant prostate cancer (mCRPCa). The incidence of prostate cancer increases proportionally with age, especially in men above 60 years of age. Studies have also shown that incidence of prostate cancer also depend on demographics and racial prevalence – prostate cancer has a low incidence in Asia (3-8 per 100,000 men per year), an intermediate incidence in Africa and Eastern Europe, and a higher incidence in North America and Western Europe. While conventional treatment modalities for localized prostate cancers include surgery, chemotherapy, cryotherapy, brachytherapy with radioactive seeds, and usage of external
