Abstract

Neuroendocrine tumors (NETs) are being seen increasingly frequently, and the only known curative treatment method is surgical resection. Peptide receptor radionuclide therapy (PRRT) is a treatment option that the most contributes to progression-free survival and overall survival in metastatic cases.β-emitting radionuclides are traditionally used for PRRT. Nowadays, alpha particle-emitting radionuclides are being developed, with advantages in terms of very high energy and a short path length, which should theoretically show higher efficacy. In this case; in a patient with NET diagnosis who had multiple (>50) lesions in the abdomen, almost all the lesions disappeared with a single dose application. This paper aims to present a case in which we observed the efficacy of225Ac-DOTATATE treatment, which is an alpha treatment.

Özet

Nöroendokrin tümörler (NET) son yıllarda giderek artan hızda ortaya çıkmakta olup bilinen tek küratif tedavi yöntemi cerrahi rezeksiyondur. Peptid reseptör radyonüklid tedavisi (PRRT) ise metastatik olgularda progresyonsuz sağkalımı ve genel sağkalıma en çok katkı sağlayan bir tedavi seçeneğidir. Ancak PRRT’de en sık tercih edilen 177Lu radyonükliti bir beta partikül yayıcısıdır. Son zamanlarda radyobiyolojik özellikleri daha güçlü olan, yüksek enerjili ve kısa menzil avantajı sunan 225Ac gibi alfa ışını yayan radyonüklidler ile PRRT’nin yapılması gündeme gelmiştir. Bu olguda; batın içerisinde çok sayıda (>50) lezyonları olan NET tanılı hastada tek doz uygulamayla lezyonların neredeyse tamamı tedavi sonrasında saptanmamıştır. Bu yazının amacı bir alfa tedavi olan 225Ac-DOTATATE tedavisinin etkinliğini gözlediğimiz olguyu sunmaktır.
