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