Hypofractionated regimen in high-risk prostate cancer will allow the investigators to deliver higher biological doses to targets in order to improve tumor control and with acceptable rectal toxicity compared to conventional fractionation.

Condition Intervention
High-risk Prostate Cancer Radiation: Standard Radiation Treatment Radiation: Hypofractionated radiation treatment

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Randomized Control Trial of Conventional Versus Hypofractionated Radiation Regimen in Single Phase Using IMRT Technique and Long Term Androgen Suppression Therapy in High-risk Prostate Cancer Patients.

Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patient is 18 years of age or older
  • Patient has histologically proven adenocarcinoma of prostate gland by needle core samples or TURP with assigned Gleason score. Prostate biopsy performed within 180 days of enrollment (date of consent).
  • Patient has high-risk prostate cancer (stage T3 or T4) and/or PSA greater than or equal to 20 ng/ml and/or Gleason score 8 to 10
  • No clinical or radiological evidence of nodal or distant metastasis(es).
  • In the opinion of the treating oncologist, patient is fit to undergo radical external beam radiotherapy to the prostate. Patients are accessible for treatment and follow up.
  • Patient does not have history of inflammatory bowel disease, anal stenosis, colorectal surgery, or repeated endoscopic examinations/interventions related to anorectal diseases.
  • No history of prostatectomy, transurethral resection of prostate on more than one occasion or previous pelvic radiotherapy.
  • No history of androgen suppression for greater than or equal to 6 months and patient is willing for androgen suppression treatment as per standard or at physician's discretion.
  • No previous malignancy within last five years except BCC or SCC skin or highly curable malignancy where a prognosis for cure is > 80%.
  • Patient signed informed consent.
