Men with localized high-risk prostate cancer carry significant risk of prostate cancer-specific mortality. The best treatment approach to minimize this risk is unclear. In this review, we evaluate the role of radiation before and after radical prostatectomy.
A critical review of the literature was performed regarding the application of external radiation therapy (RT) in combination with prostatectomy for high-risk localized prostate cancer.
Up to 70% of men with high-risk localized disease may require adjuvant therapy because of adverse pathologic features or biochemical recurrence in the absence of systemic disease. The utility of adjuvant RT among men with adverse pathologic features are well established at least regarding minimizing biochemical recurrence risk. The optimal timing of salvage radiation is the subject of ongoing studies. Neoadjuvant RT requires further study but is a potentially attractive method because of decreased radiation field sizes and potential radiobiologic benefits of delivering RT before surgery. Salvage prostatectomy is effective at treating local recurrence after radiation but is associated with significant surgical morbidity.
Combining local therapies including radical prostatectomy and RT can be a reasonable approach. Care should be taken at the initial presentation of high-risk localized prostate cancer to consider and plan for the likelihood of multimodality care.
局限性高危前列腺癌男性患者具有较高的前列腺癌特异性死亡风险。目前尚不清楚将这种风险降至最低的最佳治疗方法。在本综述中,我们评估了根治性前列腺切除术前后放疗的作用。
对关于外照射放疗(RT)联合前列腺切除术治疗高危局限性前列腺癌的文献进行了批判性综述。
高达70%的高危局限性疾病男性患者可能因不良病理特征或无全身疾病情况下的生化复发而需要辅助治疗。至少在降低生化复发风险方面,辅助放疗在具有不良病理特征的男性患者中的效用已得到充分证实。挽救性放疗的最佳时机是正在进行的研究课题。新辅助放疗需要进一步研究,但由于放疗野面积减小以及术前放疗潜在的放射生物学益处,它是一种具有潜在吸引力的方法。挽救性前列腺切除术在治疗放疗后的局部复发方面有效,但与显著的手术并发症相关。
联合包括根治性前列腺切除术和放疗在内的局部治疗可能是一种合理的方法。在初次诊断高危局限性前列腺癌时应谨慎考虑并规划多模式治疗的可能性。
