Brief Summary

Hypofractionated external beam radiotherapy has been clinically used for localized prostate cancer in view of the low estimated alpha/beta ratio of prostate cancer cells. Moderate fraction sizes of \<4Gy per fraction has been investigated in several phase II/III studies and has been found to be well tolerated with comparable biochemical control in comparison with standard fractionated dose-escalated regimens. Fraction sizes of \> 4 Gy has also been investigated in single center studies. However, its toxicity and disease control outcomes is less well known. In this Phase I/II single arm study the investigators aim to treat non-metastatic prostate cancer with stageT1-T4N0M0 and Prostate Specific Antigen (PSA) \<60 ng/ml to a regimen of 35Gy in 5 fractions delivered once a week with a view to determine acute toxicity, biochemical control with PSA and late toxicity.

Short-course Radiation Therapy

EXPERIMENTAL

Short-course Hypofractionated Once-weekly Radiation Therapy: 35Gy in 5 fractions delivered once a week.

Radiation: Short-course Hypofractionated Once-weekly Radiation Therapy

Interventions

Eligible patients will be treated with a radiation regimen of 35 Gy in 5 fractions delivered at one fraction per week at 7 day intervals. The dose of radiotherapy is based on the consensus alpha beta ratio of 1.5.

Eligibility Criteria

Age18 Years+
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically confirmed prostate adenocarcinoma.
  • History/physical examination with digital rectal examination of the prostate within 8 weeks prior to registration
  • Histological evaluation of prostate biopsy with assignment of a Gleason score to the biopsy material.
  • Clinical stage T1-T4N0M0 (AJCC 7th edition). Staging demands a multiparametric MRI of the pelvis a CT or MRI of the abdomen for T3/T4 tumors or PSA \>10 a whole body bone scan for T3/T4 tumors or PSA \>10
  • PSA \< 60 ng/mL within 180 days prior to registration. PSA should not be obtained for at least 10 days after prostate biopsy.
  • WHO performance status 0-1
  • Age ≥ 18
  • Patient must sign study specific informed consent prior to accrual.

You may not qualify if:

  • Prior or concurrent invasive malignancy (except non-melanomatous skin cancer) or lymphomatous/hematogenous malignancy unless continually disease free for a minimum of 5 years.
  • Previous radical surgery (prostatectomy) or cryosurgery for prostate cancer
  • Previous pelvic irradiation in any form.
  • Previous hormonal therapy of more than 180 days duration prior to registration.
  • Previous or concurrent cytotoxic chemotherapy for prostate cancer
  • Severe, active comorbidity, defined as follows:
  • Unstable angina and/or congestive heart failure requiring hospitalization within the last 6 months
  • Transmural myocardial infarction within the last 6 months
  • Acute bacterial or fungal infection requiring intravenous antibiotics at the time of registration
  • Chronic obstructive pulmonary disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy at the time of registration
  • Hepatic insufficiency resulting in clinical jaundice and/or coagulation defects; note, however, that laboratory tests for liver function and coagulation parameters are not required for entry into this protocol. (Patients on Coumadin or other blood thinning agents are eligible for this study.)
  • Renal insufficiency with a creatinine clearance of \<30ml/min
