Abstract
Vincristine is a vinca alkaloid chemotherapy agent used in the treatment haematological malignancies including acute lymphoblastic leukaemia (ALL) and some lymphomas. Common toxicity includes neuropathy which can be peripheral, autonomic or less commonly central1. Vincristine remains an essential chemotherapy agent in modern ALL protocols1,2,3. Its mechanism of action is by inhibiting the M phase of mitosis by binding with the protein component of microtubules. Axonal degeneration takes place when axonal transport and secretory functions are impaired thus leading to apoptosis and toxicity in neural tissue. This is typically seen within the extra‐ocular muscles and larynx in cranial neuropathy1.
