To provide an overview of the currently available literature regarding local control of primary tumor and oligometastases in metastatic prostate cancer and salvage lymph node dissection of clinical lymph node relapse after curative treatment of prostate cancer. Evidence Acquisition. A systematic literature search was conducted in 2014 to identify abstracts, original articles, review articles, research articles, and editorials relevant to the local control in metastatic prostate cancer. Evidence Synthesis. Local control of primary tumor in metastatic prostate cancer remains experimental with low level of evidence. The concept is supported by a growing body of genetic and molecular research as well as analogy with other cancers. There is only one retrospective observational population based study showing prolonged survival. To eradicate oligometastases, several options exist with excellent local control rates. Stereotactic body radiotherapy is safe, well tolerated, and efficacious treatment for lymph node and bone lesions. Both biochemical and clinical progression are slowed down with a median time to initiate ADT of 2 years. Salvage lymph node dissection is feasible in patients with clinical lymph node relapse after local curable treatment. Conclusion. Despite encouraging oncologic midterm results, a complete cure remains elusive in metastatic prostate cancer patients. Further advances in imaging are crucial in order to rapidly evolve beyond the proof of concept.
概述目前关于转移性前列腺癌原发肿瘤和寡转移灶的局部控制以及前列腺癌根治性治疗后临床淋巴结复发的挽救性淋巴结清扫的文献。证据收集。2014年进行了系统的文献检索,以识别与转移性前列腺癌局部控制相关的摘要、原始文章、综述文章、研究文章和社论。证据综合。转移性前列腺癌原发肿瘤的局部控制仍处于实验阶段,证据水平较低。这一概念得到了越来越多的遗传和分子研究以及与其他癌症类比的支持。仅有一项基于回顾性观察人群的研究显示生存期延长。对于根除寡转移灶,有几种选择,局部控制率良好。立体定向体部放疗对淋巴结和骨病变是安全、耐受性良好且有效的治疗方法。生化和临床进展均减缓,开始雄激素剥夺治疗的中位时间为2年。挽救性淋巴结清扫对于局部可治愈治疗后出现临床淋巴结复发的患者是可行的。结论。尽管中期肿瘤学结果令人鼓舞,但转移性前列腺癌患者仍难以实现完全治愈。成像技术的进一步进展对于迅速超越概念验证至关重要。
