Would you irradiate the prostate in a patient with SpaceOAR in the incorrect location but not invading rectum or prostate?

I would treat without delay if the SpaceOAR gel is not invading the rectum. It is common to see gel placements that are not ideally placed, and we have not seen any unusual or unexpected side effects/complications from this. We still see a dosimetric advantage in our treatment plans, even with a sub...

Unless the patient is very symptomatic due to poor placement of the SpaceOAR, or you cannot meet normal tissue dose constraints due to anatomic distortion created by the placement, I would proceed with treatment. SpaceOAR placements are often not perfect, especially when one is learning the procedur...

No matter how many gel placements one has performed, some will not result in the ideal “pancake” geometry between the prostate and anterior rectal wall. Experience will lessen this frequency but will not eliminate it, since variables such as unexpected fibrosis or gland size/shape can sometimes domi...
