To assess whether the response to primary androgen-deprivation therapy (PADT) and radiotherapy (RT) plus adjuvant ADT would be muted in older men, as their tumours might already be relatively androgen insensitive, because serum testosterone levels decline with increasing age.

One group of 1748 men was treated with PADT and the second group of 612 men was treated with RT (external beam RT or brachytherapy) with neoadjuvant and/or adjuv...

Dose planning was performed using a three-dimensional CT data set acquired after percutaneous applicator positioning. Magnetic resonance imaging (MRI), performed 6 and 12 weeks after therapy, was analyzed retrospectively. All MRI data sets were merged with 3D...

Conclusions The treatment of lesions after ICB occurred in 0.8% out of all patients treated with an SES. Clinical event rates during early
follow-up were low. However, the TVR rate was 16.4%, which was significantly higher when compared with other SES-treated patients
(8.4%, P = 0.04). The treatment of restenosis after ICB with SES seems to be safe and reasonably effective; however, there might be
a late catch-up phenomenon.

The use of selective internal radiation therapy for treatment of hepatocellular carcinoma and liver metastases using Y-90 labeled microspheres has become an effective and widely used treatment regimen. However, dosimetric evaluations of this treatment are still primitive as uniform distribution models based only on injected activity are often used. This investigation attempts to quantify the effectiveness of several sophisticated patient-specific techniques which utilize the source distribution of Tc-99m MAA simulation studies to perform voxelized dosimetric computations. Among these techniques are complete Monte-Carlo rad...
