Lymph nodes with isolated tumour cells, also isolated tumour cells (abbreviated ITCs) and isolated cancer cells, is the presence of rare cancer cells in a lymph node.

This article is focus on isolated tumour cells in breast pathology.

General

Definition

  • An isolated cluster of tumour cells within a lymph node in one tissue section measuring <= 0.2 mm or <=200 tumour cells.[1][2]

Significance

  • Not a significant predictor of outcome in breast pathology.[3]

Sign out

Right Breast, Modified Radical Mastectomy:
     - Two lymph nodes of six lymph nodes with ISOLATED TUMOR CELLS 
	  (<100 tumour cells per lymph node).  
	-- All lymph nodes NEGATIVE for micrometatases and 
	   NEGATIVE for macrometatases (0/4).
     - Scar and therapy changes (hyalization, calcifications) compatible 
       with treated tumour.
     - Florid epithelial hyperplasia of the usual type.
     - Please see synoptic report.

Comment:
The isolated tumour cells were demonstrated with a CAM5.2 immunostain.
