Prognostic factors for progression in atypical meningioma.

In patients with postoperative residual atypical meningiomas, by using volumetric instead of linear measurements in follow-up imaging studies, the authors detected disease progression earlier. By using this approach, treatment for recurrent disease can be instituted promptly with potentially better tumor control and less toxicity due to smaller volume of residual disease.

Transrectal implantation and stability of gold markers in prostate bed for salvage radiotherapy of macroscopic recurrences.

Background And Purpose: The objective of the study was to verify the stability of gold markers in the prostatic bed (PB) during salvage radiotherapy.

Material And Methods: Seven patients, diagnosed with a macroscopic nodule visible on MRI, underwent targeted MRI-guided biopsies. Three gold markers were implanted into the PB close to the relapsing nodule for CT/MRI fusion.
