Omega-3 Fatty Acids in Treating Patients With Advanced Prostate Cancer

Pilot Study to Determine the Optimal Dosage of Omega-3 Polyunsaturated Fatty Acid (PUFA) in Men With Advanced Prostate Cancer

This phase I trial is studying the best way to give omega-3 fatty acids in treating patients with advanced prostate cancer. Omega-3 fatty acids may slow disease progression and may be an effective treatment for patients with advanced prostate cancer

OBJECTIVES:

I. To conduct a pilot study of omega-3 polyunsaturated fatty acid (PUFA) (omega-3 fatty acid) supplementation in a group of patients with advanced prostate cancer to assess the dose of omega-3 PUFA necessary to achieve an omega-6 to -3 ratio of 1:1 on an individual basis and to assess the clinical impact of omega-3 supplementation on disease progression

OUTLINE:

Patients receive long-term omega-3 polyunsaturated fatty acid (PUFA) supplementation orally (PO).

After completion of study treatment, patients are followed up at 1, 6, and 12 months.

Inclusion Criteria:

Disease is currently controlled with androgen ablation therapy Androgen ablation is expected to continue for at least 1 year Has been treated with androgen ablation therapy for at least 1 month Stable or decreasing prostate-specific antigen (PSA) on androgen ablation therapy Stable or no visible metastatic disease on imaging Eastern Cooperative Oncology Group (ECOG) functional status of at 0 or 1

Exclusion Criteria:

Eligible for local intervention with surgery or radiation Increasing serum PSA on hormonal ablation Radiographic evidence of progression of disease on hormonal ablation Current or history of second malignancy Previously treated with chemotherapeutic agents Previous history of intermittent androgen therapy Gastrointestinal (GI) disease that impacts absorption of nutrients
