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.
Supportive Care in Advanced Prostate Cancer • Bone strengthening therapy • Radiation • Pain control therapies • Chemotherapy/novel agents

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.
Systemic Therapy in Treatment of Prostate Cancer • Discuss use of systemic therapy in metastatic prostate cancer to a} Prolong life b}Palliation or symptom control • In locally advanced prostate cancer, the goal is to improve cure rate and keep long term toxicity to a minimum
