Q

Prostate: active surveillance criteria and management

A

Offer to very low and low risk patients. May offer to favorable intermediate risk if older (age >75).

PSA q6 mos

DRE q12 mos

Biopsy within 12 months with anterior directed cores, then serial biopsy every 2 years

If rising PSA and biopsy negative: Do MRI on suspicion of anteior lesion then biopsy

Progression=new Gleason score 7 or greater or significant increase in disease volume

at 10yrs, 65% remain on active surveillance

Prostate LDR brachy: treatment narrative
I would first bring the patient to the clinic to perform a transrectal ultrasound guided volume study of the prostate. The patient would have done a bowel prep. the night before. I would place the patient in the dorsal lithotomy position and prep and drape. I would insert a foley with aerated jelly. Using a transrectal ultrasound with US gel, I would take images every 1 mm. I would assess for any pubic arch interference and record the angles of the probe and legs once finished. I would use these images to create a pre-plan using a peripheral loading technique with PTV of 3 mm laterally and 0 mm anteriorly and posteriorly. I would then take the patient to the OR and position the patient as in the pre-plan with general anesthesia. I would prep and drape the patient, place the templates, and load the seeds according to the plan. Once finished I would take AP and lateral orthogonal films in the OR to check the positioning of the seeds and do a rectal examination. The patient would then return one month later for post-implant CT and dosimetry.
