Introduction:
aim is outcome of 11C-Choline-PET guided SBRT on lymph node metastases.
Materials And Methods:
patients with 1 - 4 lymph node metastases detected by 11C-choline-PET were treated with SBRT. Toxicity, treated metastases control and Progression Free Survival were computed.
Results:
twenty-six patients, 38 lymph node metastases were irradiated. No grade ≥ 2 toxicity. Median PSA-nadir after RT was 1.02 ng/mL. Post-treatment 11C-Choline-PET showed metabolic complete response in 17 metastases (44,7%), partial response in 9 metastases (38%).
Conclusion:
SBRT is effective and safe for lymph node metastases. PET is important in identification of gross tumor and evaluation of the response.
