Radical prostatectomy provides an excellent degree of disease control for the longest period of time in patients with localized prostatic cancer. Although advocates of radiation therapy point to nearly identical survival curves for patients treated with either interstitial or external techniques, an analysis of disease-free survival suggests that radical prostatectomy yields the best long-term "cure." Crude fifteen-year survival rates of 50 per cent may be achieved with radical prostatectomy, compared with 20 per cent to 25 per cent associated with radiation therapy. Additional experience with long-term survival data is necessary before a final conclusion can be drawn from comparison of the two treatment modalities.
根治性前列腺切除术能为局限性前列腺癌患者提供最长时间的良好疾病控制。尽管放疗支持者指出，接受间质放疗或外放疗的患者生存曲线几乎相同，但无病生存分析表明，根治性前列腺切除术能带来最佳的长期“治愈”效果。根治性前列腺切除术可实现约50%的粗略15年生存率，而放疗的这一比例为20%至25%。在对这两种治疗方式进行比较并得出最终结论之前，还需要更多长期生存数据的经验。
