ABSTRACT

The unregulated growth of tumors results not only in local infiltration, but also in the spread of disease via lymphatics to lymph nodes. Although tumor dissemination to lymph nodes is common, the prevalence of nodal disease differs according to the site of the primary tumor and the underlying histopathology. For example, lymph node metastases are relatively frequent in patients with colorectal cancers but are rarely encountered in patients with soft tissue sarcomas (1) .
