Nerve-sparing surgery is the standard approach used in radical prostatectomy to enhance functional outcomes, but secondary resection might be needed in case of uncertainty regarding the complete removal of the tumour. However, direct visual guidance for resecting positive surgical margins (PSMs) during secondary resection is lacking.In a study published in BJU International, a 3D-printed prostate model was used to improve surgical precision of targeted secondary resection during nerve-sparing robot-assisted radical prostatectomy.

保留神经的手术是根治性前列腺切除术中用于增强功能结果的标准方法，但如果肿瘤完全切除不确定，可能需要进行二次切除。然而，缺乏在二次切除期间切除阳性手术切缘（PSM）的直接视觉指导。在BJU International发表的一项研究中，使用3D打印的前列腺模型来提高保留神经的机器人辅助根治性前列腺切除术中靶向二次切除的手术精度。

Overall, 100 patients undergoing nerve-sparing robot-assisted radical prostatectomy were enrolled in this prospective, multicentre study. 3D models were derived from pelvic MRI to guide intraoperative secondary resection of PSMs. This approach led to a successful conversion of PSMs to negative surgical margins in 83% of patients, 95% of whom achieved undetectable PSA levels postoperatively.

总体而言，这项前瞻性多中心研究纳入了100名接受神经保留机器人辅助根治性前列腺切除术的患者。3D模型来自骨盆MRI，以指导术中PSM的二次切除。这种方法导致83%的患者成功将PSM转换为阴性手术切缘，其中95%的患者术后达到无法检测到的PSA水平。

These results indicate that PSMs marked on a 3D model by the pathologist can improve communication between the pathologist and surgeon, ultimately improving accuracy of the secondary resection site identification. The authors acknowledged some limitations of this study, including the lack of a control group, but concluded that the integration of personalized 3D models in surgical practice could substantially optimize precision in prostate cancer secondary resection..

这些结果表明，病理学家在3D模型上标记的PSM可以改善病理学家和外科医生之间的沟通，最终提高二次切除部位识别的准确性。作者承认这项研究的一些局限性，包括缺乏对照组，但得出结论，在手术实践中整合个性化3D模型可以大大优化前列腺癌二次切除术的精确度。。
