[Radiotherapy of prostatic cancer]

Area of Science:

• Urology and Radio-Oncology
• Prostate Cancer Treatment

Context:

• Prostate carcinoma management relies on urology and radio-oncology expertise.
• Treatment approaches for prostate cancer vary geographically, with radiotherapy playing a more significant role in the USA than in Germany.
• Early-stage prostate cancer may benefit from active surveillance.

Purpose:

• To compare the roles and outcomes of surgery and radiotherapy in prostate carcinoma treatment.
• To highlight the efficacy and limitations of current treatment modalities for various stages of prostate cancer.
• To identify areas for future research and development in prostate cancer therapy.

Summary:

• Surgery is recommended for localized tumors without capsular or seminal vesicle infiltration, prioritizing nerve-sparing techniques.
• Radiotherapy is effective for advanced stages (C and D1) but shows a 10-year relapse rate of approximately 30% for stage C.
• Both surgery and radiotherapy demonstrate comparable survival data to the general population for early stages.
• Radiotherapy offers palliative benefits for bone and brain metastases.
• Further research is needed in conformal radiotherapy, neutron therapy, brachytherapy, and hyperthermia.

Impact:

• Establishes that both surgical and radiation therapies yield comparable survival outcomes for prostate cancer patients.
• Identifies the need for innovative therapeutic strategies to improve outcomes for advanced prostate cancer.
• Highlights the low incidence of severe side effects and late complications associated with radiotherapy.
