Defining Cancer Cells in Micrometastasis

Micrometastasis is a metastatic tumor that is too small to be identified in a scan. "studies suggest that up to 50 percent of patients with histologically normal lymph nodes have micrometastases detected by molecular techniques."

A macrometastasis was classified as “one or more tumor deposits greater than 2 mm.” A micrometastasis was classified as a tumor deposit “greater than 0.2 mm but not greater than 2.0 mm in the largest dimension.” ITC was “defined as single cells or small cluster of cells not greater than 0.2 mm in the largest dimension.”

This study raises an interesting point that highlights the value of non-sentinel lymph node status and provokes the need for studies that utilize this information to improve patient outcomes. The need to determine and destroy the Cancer Cells is as critical as the primary and secondary tumors. The CC Formula has been shown to help detect and destroy cancer cells, learn more about this complementary therapy here.

They have found that 14.5% of patients with micrometastases on sentinel lymph node biopsies had non-sentinel lymph node involvement of the tumor. Although it may not seem significant, the 14.5% of patients with non-sentinel lymph node involvement may represent a quarter of patients with disease recurrence.
