DISCUSSION: Various methods have been devised to detect micrometastasis including intraoperative histological analysis by frozen sections; conventional H&E stained sections, step serial sectioning, IHC and highly sensitive techniques like Reverse Transcriptase-PCR and Real time PCR.

Furthermore, in addition to a therapeutic benefit with an extended LND compared to a limited/standard LND, it is evident that an extended LND offers more accurate staging, increasing detection of micrometastasis and allowing adjuvant chemotherapy to be offered early when tumour burden is lowest.
removal of the primary tumor might eliminate a safeguard against angiogenesis and thus awaken dormant micrometastasis [small sites of metastatic cancer].
