Metastatic Prostate Cancer Common site of spread- bones Incurable, likely terminal condition Morbidity significant as it can lead to bone pain,cord compression, fractures, urinary obstruction etc. Initial therapy with hormones which is effective, but temporary
Metastatic disease: hormone therapy Hormone therapy questions: When to start? Continuous vs intermittent Which kind: Lupron/Zoladex with casodex or casodex alone (50 mg daily) or high dose casodex 150 mg daily Should we stop treatment when it stops working? What are the risks?
Common Complications of Hormone Therapy –Fatigue –Metabolic syndrome- high blood sugar, high cholesterol –Increased risk of heart problems in people who have heart disease –Hot flashes –Impotence –Osteoporosis –Gynecomastia and breast tenderness –Mood swings –Liver toxicity –Diarrhea, nausea
Strategies to address side effects of hormone therapy Hormone therapy works by suppressing the male hormone/testosterone levels. Fighting the side effects: -Increased Awareness -Stay active - Healthy diet -Ask for medication therapy for hot flashes if bothersome. -Consider intermittent hormone therapy if feasible -Monitor cholesterol, blood sugars periodically.

Zometa vs. Placebo in Hormone Refractory Metastatic Prostate Cancer Berruti et al, JNCI 2003
Bisphosphonates for Treatment of Bone Metastasis Frequency of skeletal complications due to bone metastasis Median time to first skeletal-related event compared with placebo Zoledronic acid Placebo days P=0.011 Not reached Days After Start of Therapy Patients Without Event (%) 33% 44%
Dietary factors Lycopene: A minimum of 2 servings (1 cup) per week of tomato sauce can reduce the risk of development and progression of prostate cancer. Cruciferous vegetables: at least five servings per week can decrease the risk of developing prostate cancer by 20%. Green Tea may have possible protective effects A large study showed that too much calcium (over 2000mg daily) can increase metastatic prostate cancer risk fivefold compared with those consuming <500 mg daily- Health Professionals Follow Up study
Dietary factors Vitamins within the recommended daily intake are recommended Overdosage of vitamins maybe potentially harmful Male smokers study in Finland showed that Vitamin E supplementation decreased the incidence of prostate cancer by 32% and the mortality related to prostate cancer by 41%. Beta carotene (Vit A) increased risk of lung cancer Finasteride/Proscar prevented prostate cancer and reduced the risk by 25% Selenium and Vit E trial completed and no benefit noted.
