Abstract:
Oligodendroglioma is a rare primary brain tumour. These tumours rarely metastasis extraneurally because of the absence of a lymphatic system, the presence of the blood-brain barrier and the patient's poor overall survival. Oligodendroglioma may spread via the cerebrospinal fluid or after surgical intervention. Metastasis to bone marrow is extremely rare. Oligodendroglioma is now considered a chemosensitive disease. If chemotherapy leads to prolonged survival, we may see more extraneural metastases in future.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
