Advanced Disease
 Biochemical
recurrence after
prostatectomy
 Metastatic disease


Palliative external RT
Quadramet
Salvage Radiation Therapy for
Biochemical Recurrence
 Recurrence>2years,
PSA DT>10 months
 Positive margin, extracapsular extension
 Should be used early, PSA<1(possibly
0.5)
 50-70% DFS in 5 years
 IMRT 60-70 Gy, image guidance daily
 acceptable early complications, rare late
complications

Bone Metastasis
 Pain/loss


of function
Spinal cord compression>emergency
Hip metastasis causes pain, threatens
fracture
 One
dominant site
 Multiple sites
Spine radiation
to osteoblastic
lesion
Palliative Radiation
Bone Metastasis
 Highly
effective 90% or more for pain relief
 Can be repeated
 Short course of 2 weeks, occasionally
even given in single dose, depending on
location
 Can be combined with chemo, hormone
deprivation, bone stabilization such as
vertebroplasty or fusion if needed

Bone seeking radioisotope
Systemic dose to “hot” areas
Can combine with external
May lower blood counts
May cause “flare”
Can last 3-6 months
Can be repeated
60-75% response rate
Best for patients with multiple
or migratory painful sites
Advanced prostate cancer
