Single Arm Trial of Preoperative Stereotactic Body Radiation Therapy (SBRT) for T3a or Gleason Grade Group 4 Prostate Cancer
A Single Arm Phase II Trial of Preoperative Stereotactic Body Radiation Therapy (SBRT) for T3a or Gleason Grade Group 4 Prostate Cancer
This study involves Stereotactic Body Radiation Therapy (SBRT) followed by prostatectomy (removal of the prostate). SBRT is a relatively new radiation technique in which a few doses of radiation are delivered to small, well-defined tumors. It has been used effectively in other cancers like lung and liver. The radiation will be given for only 5 days.
The purpose of this study is to compare the effects, good and/or bad, of different doses of SBRT given before prostatectomy.

Beskrivning
- Histologically proven prostate adenocarcinoma.
- Clinical stage ≤T3a based on digital rectal exam (DRE) and ≤T3a based on MRI (within 3 months); N0-Nx; M0-Mx, or Gleason score 4 + 4. No more than 1 lymph node >1 cm.
- PSA ≤ 50 ng/ml, obtained within 3 months
- Prostate volume: ≤60 cc.
- IPSS score ≤15.
- No previous radiotherapy to the prostate or lower pelvis.
- Lymph node risk of <35% using https://www.mskcc.org/nomograms/prostate/pre_op.
- No prior radical prostatectomy or cryotherapy of the prostate (prior transurethral resection or laser ablation are permitted).
- No implanted hardware or other material that would prohibit appropriate treatment planning or treatment delivery, in the investigator's opinion.
- No history of an invasive malignancy (other than this prostate cancer, or non-metastatic basal or squamous skin cancers) in the last 3 years.
- No androgen deprivation therapy (ADT) can be prescribed prior to or during radiation therapy.
- Participant must be able to have gold fiducial markers placed in the prostate. Note: patients can be enrolled after fiducial markers have been placed, as long as the procedure was done in accordance with the protocol (Section 4.2.2).

Quality of Life assessment
Tidsram: Baseline, at 2 weeks, 4 weeks, 2 months and every 3 months up to 12 months post surgery
|
Quality of Life will be assessed using 2 questionnaires: International Prostate Symptom Score (IPSS) and Sexual Health Inventory for Men (SHIM).
The IPSS is an eight question questionnaire of symptoms ranging from 0 "not at all" to 5 "always".
The SHIM is a five question questionnaire ranging from 1 "almost never or never" to 5 "almost always or always" to determine erectile dysfunction.
