Radicality of the surgical procedure in patients with intermediate and high risk melanomas is enhanced by the additional removal of the transit tract between tumor and regional lymph node (continuity dissection). After introduction of the lymphatic out flow scintigraphy in 1984, the accurate removal of the transit tract is easily possible in tumors located on the trunk, the upper arm and the thigh as well as of the head/neck region. The main reasons for the improved survival rates are the exact removal of the transit tract together with potentially existing occult tumor cells or in transit metastases, respectively, as well as ectope lymph node metastases and the consequent elective lymph node dissection.
对于中高危黑色素瘤患者，通过额外切除肿瘤与区域淋巴结之间的转移途径（连续性解剖）可提高手术的根治性。自1984年引入淋巴管引流闪烁扫描术以来，对于位于躯干、上臂、大腿以及头颈部区域的肿瘤，很容易准确切除转移途径。生存率提高的主要原因分别是准确切除转移途径以及可能存在的隐匿肿瘤细胞或移行转移灶，还有异位淋巴结转移以及随之而来的选择性淋巴结清扫。
