Zusammenfassung
Das metastasierte hepatozelluläre Karzinom (HCC) hat eine infauste Prognose. Bei fehlender,
effektiver Chemotherapie haben wir bei einer 35-jährigen Patientin mit metastasiertem
Tumorleiden und Somatostatin-Rezeptor-tragenden Tumorzellen die Therapie mit 90 Y-DOTATOC erfolgreich anwenden können. Bei dem Tracer handelt sich um das Somatostatinanalogon
Octreotid, das mit dem hochenergetischen β-Strahler Yttrium-90 (90 Y) markiert ist. Nach intravenöser Gabe des Radio-Therapeutikums reichert es sich
an die Somatostatin-Rezeptoren der Tumorzellen an. Durch die Koppelung mit dem radioaktiven
90 Y erfolgt eine lokale Tumorbestrahlung. Erste Ergebnisse der Therapie erscheinen vielversprechend.
Abstract
Patients with disseminated hepatocellular Carcinoma have a grim prognosis. An effective
systemic chemotherapeutic regimen is not yet available. We applied successfully the
radiotherapy 90 Y-DOTATOC in an 35-year old woman with metastatic disease and octrectid receptor positive
cells, as proved in advance by radionuclide imaging. 90 Y-DOTATOC represents tho somatostatin analogue octreotid which is labelled by β-emitting
radioisotope Yttrium-90 (90 Y) leading to a direct tumor radiation. Repeated applications were well tolerated
and showed a significant tumor control in our patient. The case is presented here
in addition to an overview of the literature.
