The patients are admitted both on an inpatient and outpatient basis.
Administration of Lutetium-177-DOTATATE (instead of Lutetium PSMA) allows effectively treating neuroendocrine tumors of any localization, including lung, prostate, pancreas, and colon neoplasms.
Leading hospitals that offer NETs treatment are Helios Hospital Berlin-Buch, University Hospital Frankfurt-am-Main, and University Hospital Carl Gustav Carus Dresden.
The price of therapy depends on the NET type. For instance, the average cost of NET of colon treatment with Lu-177 is 18,000 EUR.
Neuroendocrine cancer is a challenging diagnosis because NETs can develop in different parts of the body and progress differently depending on their location, causing manifestations similar to many other conditions. As a result, many patients are diagnosed with neuroendocrine tumors after the disease has already progressed to the advanced stages, making it difficult to treat with surgery and other therapies. Fortunately, therapeutic radionuclides (i.e. Lutetium-177-DOTATATE) are able to find neoplasms in any location and destroy them with targeted irradiation.

Why are NETs difficult to treat?
Treatment of neuroendocrine cancer is a challenging medical task. This is primarily due to the increasing incidences of NETs, especially in recent years. Data from various clinical trials demonstrate a five fold increase of neuroendocrine tumors of different localizations in the last five years. At the same time, the diagnostics of neuroendocrine neoplasms has also improved. Nevertheless, NETs represent a small part of all malignant neoplasms (less than 10% of all tumors) and can be considered rare tumors. These tumors most frequently occur in different parts of the gastrointestinal tract (e.g. in the pancreas, colon or appendix) and the lungs.
What are the treatment options for neuroendocrine tumors (NETs)?
Patients with neuroendocrine cancer are usually offered active surveillance, surgery, drug therapy, or radiotherapy. So, how are each of the methods applied for different groups of patients?
Active surveillance is offered to patients with neuroendocrine tumors that are less than 2 cm in size and without any hormonal activity. These neoplasms usually demonstrate no signs of aggressiveness and tend to remain stable in size, so the surveillance approach seems safe. Active surveillance includes a radiological examination (ultrasound scan/magnetic resonance imaging) every six months for the first two years after the diagnosis, and every twelve months after that.
Surgical removal is the most common and primary method of cancer management and cures neuroendocrine cancer completely in most patients. Some of these surgical procedures can be performed with minimally invasive, laparoscopic access.
Radiotherapy is usually prescribed to patients suffering with metastatic or inoperable tumors. It involves using a somatostatin-like drug, appropriately labeled with a radioactive isotope. The radiopharmaceutical is administered intravenously. It recognizes the target due to the binding of the somatostatin analog to the corresponding receptors, and allows selective irradiation of the tumor cells.
Drug therapies are usually reserved for patients with tumors that are inoperable or metastatic, biologically aggressive, and/or are not amenable to treatment with somatostatin analogs. Traditional chemotherapeutic and innovative drugs are used to selectively target the mechanisms responsible for the growth and metastasizing of these neoplasms.
Modern treatment options for NETs have been supplemented with new techniques. Traditionally, surgical treatment, radiation treatment, chemotherapy, and local therapy are used. However, alternative methods such as chemoembolization can be used as a palliative option in patients who are not eligible for radical treatment. As a rule, the effectiveness of such techniques for tumors with low hormone excretion levels is as high as 50%. Radiofrequency ablation or cryoablation can also be used in combination with, or after, cytoreductive surgery.
Looking at the new ways to treat NETs
Despite the high recurrence rate (up to 84% during five years of follow-up examinations), the survival rates are also relatively high – up to 61% of cases at five years and 35% at ten years. Such statistics are forcing the medical community to look for alternative treatment methods.
New advances in early diagnostics and the effective treatment of patients with both oncological and non-oncological neuroendocrine diseases owe much to the emergence of modern radiological diagnostic and therapeutic technologies. Radiological methods of diagnosis making and treatment are now implemented into the entire health care system. Today, no one is surprised that there are X-ray and ultrasound diagnostic rooms at health care dispensaries and district hospitals. In large cities and regional hospitals, both computed tomographic examinations and necessary radioisotope examinations, can be performed for the early detection of diseases and functional disorders of organs and systems, even before any clinical signs appear. However, modern, high-tech radiological techniques that are capable of successfully competing with traditional treatment methods, including surgery, are predominantly developed in large, research-oriented hospitals with the necessary infrastructure, highly qualified trained specialists, and proper scientific foundation.
Radionuclide therapy may be the optimal therapy for rare malignant tumors. Scientists are continuing to look for entirely new uses of radionuclide therapy. Worldwide trials are investigating the effectiveness of combining this treatment with other antitumor agents, combining different radionuclide drugs, different transport proteins and isotopes, the possibility of expanding the indications for use, and the possibility of injecting the drug into the arteries that feed the neoplasm (to avoid the drugs entering the systemic bloodstream), this would allow the dosage to be safely increased without the risk of severe side effects developing.
What is radionuclide therapy, and how does it work?
Most neuroendocrine tumors contain a large number of somatostatin receptors on their surfaces. Therefore, innovative treatment methods that act on the receptors have demonstrated a significant advantage in the treatment of NETs.
Radionuclide therapy with Lutetium-177 for neuroendocrine tumors uses a radiation source (the so-called beta emitter) bound to somatostatin analogs, which are administered intravenously. The radiation source enters the bloodstream and then finds the tumor and its metastases, penetrating the tumor cells and irradiating them. The obligatory requirement for this Lutetium therapy is a large number of somatostatin receptors on the tumor cells. And therefore, before starting treatment, a somatostatin receptor PET/CT is performed to evaluate the number of receptors.
In addition, different types of malignant tumors can be treated with the radionuclide therapy with Lu-177, which targetedly delivers potent doses of radiation directly to the tumor cells, using the receptors detected. As a result, radiation therapy causes the tumors to shrink as the cancer cells die.
Advantages of the Lutetium therapy
A key advantage of treatment with Lutetium-177 for neuroendocrine tumors over other radiation therapy modalities (which, generally, can be considered similar in their mechanisms of action) is the ability of direct delivery of therapeutic radionuclides to the tumor or target site. This works because some tumors have an excess (overexpression) of peptide receptors compared to normal tissues. Lu-177 can be combined with the corresponding peptide (or its analog) to bind to the specific tumor. With a gamma-emitting radionuclide, this method can be used to receive images with a gamma camera or PET scanner for tumor detection.
The fact that the Lu-177 beta-emitter penetrates tissue to a depth of no more than 2 mm makes most patients with neuroendocrine tumors candidates for Lutetium therapy. Thus, even small cancer foci can be irradiated with high precision, without affecting the surrounding tissue significantly.
Since the protein molecule binds specifically to the somatostatin receptors on tumor cells, the therapeutic agent accumulates only in the tumor, allowing for the targeted irradiation of the malignant cells. The radiation in the human tissue, in this case, has a radius action of only a few millimeters. Thus, a higher and more effective dose of radiation can be targeted directly against the cancer cells using Lu-177 based medicine, compared to traditional radiation therapy.
Various clinical trials have demonstrated that tumor progression can be slowed down with the help of Lutetium therapy. Therapy can reduce pain, reduce tumor activity, and significantly improve a patient’s quality of life.
The fact of the matter is, that some innovative therapies have no alternative for deadly diseases. For example, the latest types of immunotherapy are used abroad for patients with advanced forms of cancer. If successful, they make it possible to achieve a complete remission, with the disappearance of the primary tumor and all the metastases. Treatment with innovative methods, like Lutetium therapy, is also used to avoid traumatic interventions. Therefore, treatment with Lu-177 can save the lives of many patients.
The cost of treatment with Lu-177
The cost of treatment depends on the necessary diagnostic procedures to be performed, the chosen treatment tactics, and the duration of the stays in hospitals. But, even before arriving, patients are usually curious about the prices of treatment with Lutetium-177 for neuroendocrine tumors. The cost of treatment also varies depending on the country patients want to undergo Lutetium therapy in. For example, the cost of treatment with Lutetium therapy in Germany starts at 13,965 EUR, and the cost of treatment in Austria starts at 12,000 EUR.
