Abstract

OBJECTIVE: Stereotactic radiosurgery is an alternative treatment option in recurrent or residual pituitary adenomas. In this study, patients with pituitary adenoma who underwent stereotactic radiosurgery (SRS) with Cyberknife® were evaluated the response to treatment.METHODS: Between January 2010- June 2013, 7 patients with pituitary adenomas underwent SRS in Ankara Oncology Hospital. Median age was 36 (range, 30-60) and 71% of cases (n=5) were male gender. All except one patient with hemophilia underwent surgery. Four cases with functioning adenomas were unresponsive to medical treatment and because of recurrent tumors, SRS was applied. Radiosurgery were performed in two cases due to residual tumor after surgery and one case due to medically inoperable. The median prescribed dose was 22 Gy (range, 20-25 Gy), in 3 and 5 fractions, with median 84% isodose line (range, 80%-93%). RESULTS: The median follow-up time was 18 months (range, 14-55 months). A 55 months follow-up, one patient (non-functioning pituitary adenoma) showed clinical and radiological complete response. One patient with a functioning pituitary adenoma was progressing. In 6 of the seven patients (86%) tumor control were achieved. CONCLUSION: Stereotactic radiosurgery is a safe and effective treatment option in the treatment of recurrent or residual pituitary adenomas.

Özet

AMAÇ: Kalıntı ve/veya nüks hipofiz adenomlarının tedavisinde stereotaktik radyocerrahi alternatif bir tedavi seçeneğidir. Bu yazıda kliniğimizde Cyberknife® stereotaktik radyocerrahi (SRC) uyguladığımız hipofiz adenomlu hastaların tedaviye yanıtlarının değerlendirilmesi amaçlanmıştır.YÖNTEMLER: Ankara Onkoloji Hastanesi Radyasyon Onkolojisi Kliniğinde, Ocak 2010- Haziran 2013 tarihleri arasında beşi fonksiyonel ve ikisi non-fonksiyonel olmak üzere toplamda yedi hipofiz adenomlu olguya SRC uygulandı. Olgularda ortanca yaş: 36 (aralık, 30-60) ve olguların % 71'i (n=5) erkek cinsiyet idi. Hemofili hastalığı olan bir hasta dışındaki tüm olgulara cerrahi uygulanmış idi. Fonksiyonel adenomlu dört olgu medikal tedaviye yanıtsız idi ve yinelemiş tümörlerinin olması nedeni ile radyocerrahi kararı alındı. İki olgu ise cerrahi sonrası kalıntı tümör nedeni ile, bir olguda cerrahi yapılamadığı için primer olarak SRC uygulandı. Reçete edilen ortanca doz, 22 Gy (aralık, 20-25 Gy), 3-5 fraksiyonda, ortanca % 84 (aralık, % 80-% 93) izodoz ile uygulandı.BULGULAR: Ortanca takip zamanı: 18 ay (aralık, 14-55 ay) idi. Bir olgu (non-fonksiyonel) 55 aylık izleminde klinik ve radyolojik olarak tam yanıt gösterirken, bir fonksiyonel hipofiz adenomlu olgu ise progrese oldu. Yedi olgunun 6'sında (% 86) radyolojik olarak tümör kontrolu sağlandı.SONUÇ: Kalıntı ve/veya nüks hipofiz adenomlarının tedavisinde stereotaktik radyocerrahi etkin ve güvenli bir tedavi seçeneği olabilir.
