Clinical staging is important for determining the extent of disease in animals with malignant cancers. The status of the lymph node will help determine whether adjuvant treatment is indicated. Historically, the regional anatomic lymph node has been sampled to determine the presence or absence of metastatic disease, but there is increasing evidence that the regional anatomic lymph node is often different to the sentinel lymph node. As a result, several sentinel lymph node mapping techniques have been described for more accurate clinical staging of oncologic patients.

非选择性淋巴结清扫和前哨淋巴结定位和活检。

临床分期对于确定恶性肿瘤动物的疾病范围很重要。淋巴结的状态将有助于确定是否需要辅助治疗。历史上，已经对区域解剖淋巴结取样以确定是否存在转移性疾病，但是越来越多的证据表明，区域解剖淋巴结通常不同于前哨淋巴结。结果，已经描述了几种前哨淋巴结标测技术，以用于肿瘤患者的更准确的临床分期。
