  8. Adequate laboratory parameters

    • Absolute Neutrophil Count (ANC) ≥ 1.5 x 10^9/L
    • Platelet count (PLT) ≥ 100 x 10^9/L
    • Haemoglobin (Hb) ≥ 90 g/L
    • Serum creatinine (Cr) ≤ 1.5 x upper limit of normal(ULN) or creatinine clearance > 50 ml/min.
    • Total bilirubin (TBIL) ≤ 1.5 x ULN.
    • Glutamic oxaloacetic transaminase (AST/SGOT) or glutamic alanine transaminase (ALT/SGPT) levels ≤ 2.5 x ULN.
    • International normalised ratio (INR) ≤1.5, prothrombin time (PT) and activated partial thromboplastin time (APTT)≤1.5 x ULN .
    • Left ventricular ejection fraction (LVEF) ≥ 50%.
  9. Patients able to comply with the protocol. Arm 1 subjects are proposed to receive salvage radiation therapy, while arm 2 subjects are not suitable for or refuse radiation therapy.

  10. Signed informed consent.

Main

Exclusion Criteria
  1. Prior hormonal therapy (antiandrogens or gonadotropin releasing hormone) or prior radiotherapy to pelvic .

  2. Postoperative biochemical recurrence with PSA > 2 ng/ml.

  3. Postoperative pathology containing neuro-endocrine differentiation or small cell features.

  4. Prior malignancy other than prostate cancer in the past three years.

  5. History of any of the following:

    • Seizure or known condition that may pre-dispose to seizure
    • Severe or unstable angina, myocardial infarction, symptomatic congestive heart failure, arterial or venous thromboembolic events (eg, pulmonary embolism, cerebrovascular accident including transient ischemic attacks), or clinically significant ventricular arrhythmias within 6 months prior to entry.
    • Active infection (eg, human immunodeficiency virus [HIV] or viral hepatitis)
  6. Any other serious or uncontrolled illness which in the opinion of the investigator makes it undesirable for the patient to enter the trial.
