Brief Summary
RATIONALE: Soy protein/isoflavones and venlafaxine may help relieve hot flashes in patients receiving hormone therapy for prostate cancer. It is not yet known whether soy protein/isoflavones are more effective than venlafaxine when given together or with a placebo in treating hot flashes. PURPOSE: This randomized phase III trial is studying soy protein/isoflavones and venlafaxine to compare how well they work when given together or with a placebo in treating hot flashes in patients receiving hormone therapy for prostate cancer.

Outcome Measures
Primary Outcomes (1)
Hot Flash Symptom Severity Score
The primary objective of this randomized trial is to assess the effect of soy and Venlafaxine on the hot flash symptom severity score in men undergoing hormonal manipulation for treatment of prostate cancer. Hot flash severity will be quantitated using the symptom diary (as the sum of the number of hot flashes (any number greater than or equal to 0) times their severity (0=none, 1=mild, 2=moderate, 3=severe)). The primary end point is the 12 week hot flash score relative to the baseline value (i.e., 100\*(12 week score)/baseline score). The range is 0 to infinity. Lower values represent a better outcome.

Study Arms (4)
Arm I - Placebo
ACTIVE COMPARATORPatients receive oral placebo pill and oral placebo powder once daily.
Arm II - Soy
ACTIVE COMPARATORPatients receive oral placebo pill and oral soy protein/isoflavones powder once daily.
Arm III - Venlafaxine
EXPERIMENTALPatients receive oral Venlafaxine pill and placebo powder once daily.
Arm IV - Soy + Venlafaxine
PLACEBO COMPARATORPatients receive oral Venlafaxine pill and soy protein/isoflavones powder once daily.
Interventions
Soy protein powder (20gm) orally 160 mg of total isoflavones isocaloric supplement of casein protein
Patients receive oral venlafaxine 75mg.
Placebo powder (20gm casein protein) orally 0 mg of total isoflavones
Patients receive oral placebo pill.
Eligibility Criteria
You may qualify if:
- Histologic documentation of prostate cancer, any stage Life expectancy of \> nine months
- Prior or current androgen deprivation for treatment or control of prostate cancer to include:
- Bilateral Orchiectomy
- LHRH agonist (with or without antiandrogen therapy) ie: leuprolide (Lupron), goserelin (Zoladex), bicalutamide (Casodex), flutamide (Eulexin), or similar agents
- Chemotherapy
- Radiation (Patients may undergo concurrent radiation therapy to the prostate, prostate + seminal vesicles, and/or pelvis). Seed implants are allowed
- Participant report of hot flash frequency of an average of four or more per day, as defined by sweating, flushing, sensation of warmth, night sweats (Average of 28 per week)
- Hot flashes must be moderate or severe (See appendix A for hot flash definitions)
- Grade 2 (Moderate flashes) are warmer, produce obvious perspiration, and last 2 to 3 minutes
- Grade 3 (Severe flashes) causes profuse perspiration, generate intense heat, last longer and interfere with ongoing activity
- Age \>21
- No allergies to soy or dairy products
- No current use of SSRIs, SNRI's, MAOIs, or Linezolide
- No uncontrolled hypertension (160/90) or greater than Class I American Heart Association functional capacity
- No history of mania, hypomania, bipolar disorder, or anorexia nervosa
- +8 more criteria
You may not qualify if:
- Anticipated changes in prostate cancer treatment plan (i.e., hormonal manipulation, changes in chemotherapy)
- Concurrent antidepressant therapy
- History of intolerance to venlafaxine
- Recent (within 14 days) use of venlafaxine (Effexor XRTM), monoamine oxidase inhibitor, SSRI (selective serotonin reuptake inhibitor), or SNRI (selective norepinephrine reuptake inhibitor)
- History of seizure disorder
