Lymphatic drainage from the prostate is mainly directed towards pelvic sentinel lymph nodes, although presacral and para-aortic sentinel nodes have also been found with lymphatic mapping. In this case series, we describe direct lymphatic drainage towards the anterior abdominal wall in 3 patients with prostate cancer. In one patient, the sentinel node at the anterior abdominal wall contained metastasis. Sentinel node sampling provides the possibility to map all nodes on a direct drainage pathway, in contrast to regional pelvic nodal dissection with which some sentinel nodes may be missed.
前列腺的淋巴引流主要朝向骨盆前哨淋巴结，但也有研究发现，通过淋巴显影，前列腺癌也可向前腹壁的前哨淋巴结转移。本研究报道了 3 例直接引流至前腹壁的前列腺癌患者，其中 1 例前腹壁前哨淋巴结转移。前哨淋巴结活检提供了对直接引流途径上所有淋巴结进行定位的可能性，而不同于可能遗漏部分前哨淋巴结的区域盆腔淋巴结清扫。
