Zusammenfassung
Hintergrund
Trotz einer zunehmenden Zahl an Berichten ist das Merkel-Zell-Karzinom eine seltene Erkrankung. Berichte über eine primäre Strahlentherapie sind selten.
Patient und Methode
Bei einer 84jährigen Patientin mit lokal rezidiviertem Merkel-Zell-Karzinom am Oberlid erfolgte eine primäre hypofraktionierte Strahlentherapie mit 70-kV-Röntgenstrahlen (50 Gy in zehn Fraktionen von je 5 Gy über fünf Wochen).
Ergebnis
Der Tumor zeigte eine rasch einsetzende komplette Remission, 24 Monate nach Ende der Therapie ist die Patientin ohne Hinweis auf ein Lokalrezidiv oder Fernmetastasen.
Schlußfolgerung
Der vorgestellte Fall bestätigt erneut die Strahlenempfindlichkeit des Tumors und unterstreicht die Bedeutung der Radiotherapie nicht nur als Salvage-Maßnahme.
Abstract
Background
Despite an increasing number of reports Merkel-cell-carcinoma still is a rare neoplasm. Reports on radical radiotherapy are sparse.
Patient and Method
We report on a successful radical radiotherapy of a recurrent Merkel-cell-carcinoma of the eyelid in an 84-year old woman, using a hypofractionated treatment of 50 Gy with 70 kV-X-rays, 10 fractions of 5 Gy within 5 weeks.
Result
Rapid and complete remission was achieved, with no signs of local or distant failure 24 months after the end of therapy.
Conclusion
The case reported on highlights the radiosensitivity of this tumor and the role of radiotherapy not merely as salvage procedure.
