CyberKnife Ablation of a Solitary Para-Aortic Lymph Node Metastasis After Robotic-Assisted Radical Prostatectomy

Introduction: Radical prostatectomy is an effective curative treatment option for organ-confined prostate cancer. There is a recent trend in offering curative treatment to patients with oligometastatic disease. More sensitive imaging modalities can identify oligometastatic disease that is not usually detected by conventional imaging techniques. Case presentation: We present a case in which a solitary left para-aortic metastatic lesion was ablated; using CyberKnife image-guided stereotactic radiotherapy after robotic-assisted radical prostatectomy with negative margins and negative lymph node status. Conclusion: With the increasing number of patients diagnosed with oligometastatic prostate cancer, there is a paradigm shift towards its treatment with curative intent. The unusual sites of metastasis, can be cured effectively with Cyber Knife technology, whilst minimising adverse effects. Our report is an effort to highlight this technique as an effective treatment modality to be used and popularised as a standard option.
