Summary
Established prostate cancer treatments like orchidectomy and oestrogen therapy remain relevant. While effective for androgen ablation, they have side effects, necessitating careful consideration of risks and benefits.
Area of Science:
- Oncology
- Endocrinology
- Urology
Background:
- Therapeutic options for prostate cancer have expanded over the last two decades.
- Long-established treatments such as orchidectomy and oestrogen therapy may still hold a role.
Purpose of the Study:
- To evaluate the continued relevance and associated risks of orchidectomy and oestrogen therapy in prostate cancer management.
- To explore potential strategies for mitigating the adverse effects of these treatments.
Main Methods:
- Review of established treatments for prostate cancer, focusing on orchidectomy and oestrogen therapy.
- Analysis of efficacy, side effect profiles, and patient survival rates associated with these interventions.
Main Results:
- Orchidectomy offers comparable survival to other androgen ablation methods but causes significant side effects (loss of libido, hot flushes, osteoporosis).
- Oral oestrogens show potential efficacy but carry risks of gynaecomastia, sexual dysfunction, and cardiovascular toxicity.
- Lower doses, combination therapies (with antiandrogens/antithrombotics), and parenteral administration may improve oestrogen tolerability.
Conclusions:
- Orchidectomy is indicated for immediate testosterone reduction, non-compliance, or cost objections to medical therapy.
- Oestrogen therapy, particularly parenteral forms and low-dose combinations, warrants further research to optimize its use and minimize cardiovascular risks in prostate cancer treatment.
