简要总结
In this study the investigators will include patients with high risk of PSA relapse scheduled to receive curative surgical treatment. This include patients with high Gleason score (9-10) or micrometastatic disease (tumor cells detected in specimens obtained from bone marrow). They are scheduled for regular follow-ups with PSA measurements. We have previously published that some patients with metastatic prostate cancer may respond to DC-vaccination with tumor mRNA, with a decrease in PSA. PSA response is related to immunological response. Patients receiving DC-vaccination may have a reduced risk of PSA relapse or increased time to PSA relapse. Previous experience with different DC-vaccine protocols in our hospital has resulted in only minor side-effects (grade 1-2 fever, rubor, fatigue, local swelling or pain).

入选标准
- •Radical prostatectomy. Preferably accessible tumor tissue with enough volume and quality for vaccine production (extraction of tumor mRNA).
- •Pathological stage pT2 - pT3b and Gleason score 7B-10, pN0, pN+ or pNx.
- •Must be ambulatory with an ECOG performance status 0 or
- •Tumor cells detected in bone-marrow samples (micrometastatic disease). Patients with Gleason score 9-10 or pT3b Gleason score 8 may also be included with negative bone-marrow aspiration. Bone-marrow aspirates and plasma for microRNA will be obtained before start of surgery.
- •Must be at least 18 years of age and less than 75 years.
- •PSA < 0.2 µg/L within 6 weeks after surgery.
- •Must have lab values as the following:
- •ANC ≥ 1.5 x 109/L; Platelets ≥ 100 x 109/L; Hb ≥ 9 g/dL (≥ 5.6 mmol/L); Creatinine ≤ 140 μmol/L (1.6 mg/dL)- if borderline, the creatinine clearance ≥ 40 mL/min; Bilirubin within the upper limit of normal; ASAT and ALAT ≤ 2.5 the upper limit of normal; Albumin levels above lower normal value
- •No metastasis on bone scans or MRI, last 3 months before inclusion.
- •Signed informed consent and expected cooperation of the patients for the treatment and follow up must be obtained and documented according to ICH/GCP, and national/local regulations.
排除标准
- •Previous treatment with LHRH (Luteinizing Hormone-Releasing Hormone) agonist.
- •Previous anti-androgen treatment (Casodex).
- •History of prior malignancy within the last 5 years, with the exception of curatively treated basal cell carcinoma.
- •Active infection requiring antibiotic therapy.
- •Significant cardiac or other medical illness that would limit activity or survival, such as severe congestive heart failure, unstable angina, or serious cardiac arrhythmia.
- •Adverse reactions to vaccines such as asthma, anaphylaxis or other serious reactions.
- •History of immunodeficiency or autoimmune disease such as rheumatoid arthritis, systemic lupus erythematosus, scleroderma, polymyositis-dermatomyositis, juvenile onset insulin dependent diabetes, or a vasculitic syndrome.
- •Positive testing for syphilis (treponema pallidum), HIV, Hepatitis B and C
- •Use of systemic glucocorticoids.
- •Any reason why, in the opinion of the investigator, the patient should not participate.
