PRRTmeningioma Meningiomas, the most common primary brain tumors in adults, accounting for approximately a third of all intracranial neoplasms, can present complex treatment challenges作者：T Graillon·2023·被引用次数：11—Today, Anti-VEGF and mTOR inhibitors are the most used and probably the most active drugs in aggressivemeningiomas.Peptideradioactiveradiationtherapy aims .... While surgery and radiotherapy remain primary interventions, systemic medical therapies are increasingly considered for treatment-refractory cases. Among these emerging treatments, peptide receptor radionuclide therapy (PRRT) has shown promise, particularly for advanced, recurrent, or progressive meningiomas. However, as with any medical intervention, understanding the contraindications and potential side effects associated with peptides is crucial for patient safety and treatment efficacy作者：M Unterrainer·2023·被引用次数：26—Somatostatin-receptor (SSTR)-targeted PET/CT provides important clinical information in addition to standard imaging inmeningiomapatients..

Peptide Receptor Radionuclide Therapy (PRRT) in Meningioma Treatment

PRRT is a targeted therapy that delivers high doses of radiation directly to tumor cells. This approach leverages the expression of somatostatin receptors (SSTRs) on many meningiomas, similar to their presence on neuroendocrine tumors. By using radiolabeled peptides that bind to these receptors, PRRT can effectively deliver therapeutic radiation to the tumor site. Studies have demonstrated that PRRT meningioma treatment can be safe, well-tolerated, and effective in controlling disease progression in patients with meningiomasCyproterone acetate and the risk of meningioma. For instance, research has indicated that PRRT with 111In-Pentetreotide can be a safe and effective option for disease control. Furthermore, new research presented in The Journal of Nuclear Medicine deems PRRT a safe and efficacious alternative for advanced meningiomas.

Despite the therapeutic potential, certain conditions and patient factors can serve as contraindications to PRRT. The Joint EANM/EANO/RANO/SNMMI practice guideline adapts contraindications for PRRT from guidelines for neuroendocrine tumorsResearch has shown that Depo-Provera use may be tied to a type of tumor called ameningioma.

While absolute contraindications are not extensively detailed in publicly available summaries, general principles of patient suitability for radiation therapy apply.作者：C Ogasawara·2021·被引用次数：379—MECs also protect against infection and neurodegeneration via phagocytosis of bacteria and apoptotic bodies, as well as macropinocytosis of neurotoxicpeptides... This includes assessing overall health, renal and hepatic function, and the presence of other severe comorbidities that could compromise a patient's ability to tolerate treatment and its associated side effects. Comprehensive patient evaluation by a multidisciplinary team is essential to determine eligibility.

While these findings relate to risk factors for developing meningiomas, they underscore the importance of a thorough medical history, including previous or current use of hormonal medications, when considering any treatment involving peptides.Peptide Receptor Radionuclide Therapy in Patients with ...

Other factors that may influence treatment decisions, though not strictly considered absolute contraindications for peptides in PRRT, can include:

* Radiation exposure: Certain familial syndromes and prior exposure to ionizing radiation can increase the risk of developing meningiomas. While this is a risk factor for the disease itself, significant prior radiation to the same treatment area might be a consideration for subsequent therapies.

* Specific Gene Mutations and Familial Syndromes: While research is still evolving, understanding the genetic landscape of meningiomas may reveal specific contraindications in the future.Theragnostic Use of Radiolabelled Dota-Peptides in ...

* Pregnancy and Breastfeeding: As with most radiation therapies, PRRT is contraindicated in pregnant or breastfeeding individuals due to potential harm to the fetus or infant.
