CIPN has a classic presentation of sensory neuropathy with numbness and paresthesia in a “glove and stocking” distribution, but PD-1 inhibitor-associated peripheral neuropathy has a wider spectrum of presentation ranging from headaches and dizziness to sensory or motor neuropathies to cranial neuropathies with meningitis and cranial nerve involvement or syndromes resembling Guillain–Barre or myasthenia gravis [13,14]. Here, PDCD1 is linked to peripheral neuropathy.
