E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate the potential benefit, in terms of biochemical progression free survival, of a
combined adjuvant treatment consisting of short term androgen suppression in addition to RT in comparison to RT alone, delivered either
immediately following prostatectomy or in an early salvage setting, when the PSA starts to rise above undetectable levels. The population
considered consists of patients who had a baseline PSA ≤ 30 ng/ml, who underwent an operation for cT1-2-3a cN0M0 prostate cancer and who presented post-operatively with pathologic stage pT2 R1 / pT3a-b R0-1 cN0M0, Gleason score 5-10 and an undetectable or very low (< 0.2 ng/ml) post-operative PSA. |
|
E.2.2 | Secondary objectives of the trial |
A translational research study involving proteomics and collection of tissue micro-arrays for future research will be carried out in selected centers. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Patients with clinical stage cT1-2-3aN0M0 prostate cancer clinically assessed after a preoperative work-up including physical examination, chest X-ray, bone scan, CT scan or MRI of the entire pelvis and abdomen.
- Pre-operative PSA ≤ 30ng/ml
- Presenting after radical prostatectomy (all techniques allowed:retropubic, laparoscopic or perineal) with:
*Gleason sum 5-10
*Pathologic stage pT2R1 (positive surgical margins with at least a tumor trans-section higher than 2 mm) or pT3a-b (irrespective of margin status)
*Negative lymph node (LN) status (pN0) by LN sampling or LN dissection or cN0 (by MRI) pNx. *Post-operative PSA undetectable (PSA is below the detection level of the laboratory) within 3 months of surgery
- Age ≤ 80 years.
- WHO performance status 0-1.
- Normal organ functions as shown by all of the following (measured within 2 weeks prior to randomization):
*hemoglobin ≥ 110 g/l
*WBC ≥3 x 109/l
*platelet count ≥ 100 x 109/l
- Medically fit to receive radiation therapy. Preferably the patient should be fully continent at randomization.
- Before patient randomization, written informed consent must be given according to ICH/GCP, and national/local regulations. Patients can be randomized in this trial only once.
- To enter the trial in the "immediate post-operative" setting
* External irradiation must be planned to start within 26 weeks after surgery. Randomization should ideally take place within 22 to maximum 25 weeks after surgery
and minimum 1 week before the start of the post-operative treatment and the PSA should be undetectable or very low (< 0.2 ng/ml) within 2 weeks before
randomization.
- To enter the trial in the "early salvage" setting
* biochemical failure defined by rising PSA documented
* Either by 3 PSA measurements (nadir and 2 consecutive increases measured at least 2 weeks apart) with final PSA value > 0.1 ng/ml and ≤ 0.5 ng/ml;
* Or, in the case where the 3rd value is not > 0.1 ng/ml, by 4 PSA measurements (nadir and 3 consecutive increases measured at least 2 weeks apart).
* Final measurement should be within 2 weeks before randomization and ≤ 0.5 ng/ml. Salvage treatment must be planned to start within 2 months after biochemical
failure. Randomization should take place minimum 1 week before starting the salvage treatment. |
|
E.4 | Principal exclusion criteria |
- prior pelvic irradiation.
- prior bilateral orchiectomy.
- prior chemotherapy within the 5 years prior to randomization.
- prior hormonal treatment except neo-adjuvant treatment lasting ≤ 3 months.
- other malignancy except adequately treated basal cell carcinoma of the skin or other malignancy from which the patient has been disease free for at least 5 years.
- psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before randomization in the trial.
