Trial Description

Summary

This randomized phase III trial studies intensity-modulated radiation therapy (IMRT) or proton beam therapy (proton beam radiation therapy) (PBT) in treating patients with prostate cancer. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. It is not yet known whether IMRT or PBT is more effective in treating patients with prostate cancer.

Further Study Information

PRIMARY OBJECTIVES:

I. Compare the reduction in mean Expanded Prostate Cancer Index Composite (EPIC) bowel scores for men with low or intermediate risk prostate cancer (PCa) treated with PBT versus IMRT at 24 months following radiation (where higher scores represent better outcomes).

SECONDARY OBJECTIVES:

I. Assess the effectiveness of PBT versus IMRT for men with low or intermediate risk PCa in terms of disease-specific quality of life as measured by patient-reported outcomes, perceptions of care and adverse events.

II. Assess the cost-effectiveness of PBT versus IMRT under current conditions and model future cost-effectiveness for alternative treatment delivery and cost scenarios.

III. Develop predictive models to examine the associations between selected metrics of individual radiation dose distributions (including both the planned and delivered doses estimated based on serial imaging) and patient reported bowel, urinary, and erectile function.

IV. Identify and evaluate biomarkers of prostate cancer behavior and response to radiotherapy.

V. Assess longer-term rates of disease-specific and overall survival as well as development of late effects such as second cancers.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients undergo IMRT 5 days a week for 8.5-9 weeks.

ARM II: Patients undergo PBT 5 days a week for 8.5-9 weeks.

After completion of study treatment, patients are followed up at 3, 6, 9, 12, 18, 24, 36, 48, and 60 months.

Eligibility Criteria

Inclusion Criteria:

Gleason score, obtained at biopsy, =< 6 or Gleason score 3 + 4 = 7 or 4 + 3 = 7 if PSA < 20

Participants who are currently receiving dutasteride (or have received it within the last 90 days) or finasteride (or have received it within the last 30 days) must have a PSA of =< 10

Participants must have a complete history and physical examination within 45 days of study entry

Participants must have a digital rectal examination (confirming clinical stage T1c to T2b) of prostate within 180 days of study entry

Eastern Cooperative Oncology Group (ECOG) performance status 0-1

Prostate specific antigen (PSA) < 20, within 6 months of study entry

Males diagnosed with histologically confirmed, adenocarcinoma of the prostate based on core biopsy within 365 days of study entry from transrectal ultrasonography (TRUS)

American Joint Committee on Cancer (AJCC) 7th edition clinical stages T1c to T2b

Exclusion Criteria:

Suspected distant metastases, or clinically or pathologically involved lymph nodes must be confirmed by a computed tomography (CT) scan within 365 days of study entry

Prior surgery (not including TURP), cryosurgery, radiofrequency ablation, chemotherapy or radiation for pCa

Individuals with any of the following conditions are excluded from this study:

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

History of hepatic insufficiency resulting in clinical jaundice and/or coagulation defects within the last 12 months

Individuals with major medical or psychiatric illness which would prevent the completion of study treatment and/or interfere with follow up are excluded from this study

Individuals with a history of other malignancies are ineligible unless they have been disease-free for at least 5 years and are deemed by the investigator to be at low risk for recurrence of that malignancy; individuals diagnosed and treated for non-metastatic basal cell or squamous cell carcinoma of the skin are eligible

Hip prosthesis, inflammatory bowel disease or connective tissue disorder such as active scleroderma or lupus (radiotherapy contraindications)

Prior or planned androgen deprivation or bilateral orchiectomy

Individuals who have acquired immunodeficiency syndrome (AIDS) (cluster of differentiation [CD] 4 < 200 or an AIDS-defining illness) or are human immunodeficiency virus (HIV)-positive and not on highly active antiretroviral therapy (HAART) are ineligible
