Classic syndrome with cancer diagnosed within 5 years of neurological symptom
Non-classic syndrome that resolves or significantly improves after cancer treatment without concomitant immunotherapy, provided that the syndrome is not susceptible to spontaneous remission
Non-classic syndrome with cancer diagnosed within 5 years of nuerological symptoms development and positive neuronal antibodies
Neurological syndrome (classic or not) without cancer and with well characterized antineuronal antibodies (Hu, Yo, Ma, CV2, Ampiphysin and Ri)
Possible PND
Classic syndrome with high risk of cancer without antineuronal antibodies
Neurological syndrome (classic or not) without cancer and with partly characterized antineuronal antibodies
Non-classic syndrome with cancer within 2 years of neurological symptom development without neuronal antibodies
