Paraneoplastic neurologic syndromes can present with manifestations at any level of the neuraxis. In patients with high clinical suspicion of a paraneoplastic neurologic syndrome, cancer screening and treatment should be undertaken, regardless of the presence of a neural antibody.

In this episode, Katie Grouse, MD, FAAN, speaks with Anastasia Zekeridou, MD, PhD, author of the article “Paraneoplastic Neurologic Disorders,” in the Continuum August 2024 Autoimmune Neurology issue.

Dr. Grouse is a Continuum® Audio interviewer and a clinical assistant professor at the University of California San Francisco in San Francisco, California.

Dr. Zekeridou a senior associate consultant in the departments of neurology, laboratory medicine, and pathology, and for the Center for Multiple Sclerosis and Autoimmune Neurology at Mayo Clinic in Rochester, Minnesota.

Dr Grouse: This is Dr Katie Grouse. Today, I'm interviewing Dr Anastasia Zekeridou about her article on classical paraneoplastic neurologic disorders, which is part of the August 2024 Continuum issue on autoimmune neurology. Welcome to the podcast, and please introduce yourself to our audience.

 

Dr Zekeridou: Hi. Thank you, Dr Grouse. I'm always excited to talk about paraneoplastic neurological diseases. So, I'm an autoimmune neurologist at Mayo Clinic in Rochester, and I spend my time between the lab and seeing patients in the autoimmune neurology clinic.

 

Dr Grouse: Thank you so much for joining us, and we're really excited to talk about this really important topic. So, to start, I'd like to ask what, in your opinion, is the key message from this article.

 

Dr Zekeridou: That's a good question - there are a lot of messages, but maybe if I can distill it down. For me, one of the first things is that paraneoplastic neurological diseases can actually affect any level of the neuraxis. It can manifest with different types of presentations. If we do suspect a paraneoplastic neurological syndrome, then we need to look for the cancer, and then if we're not certain, even do an immunotherapy trial. A negative antibody does not make for an absence of a paraneoplastic neurological disease (because, often, we depend a lot on them), but you can see patients with paraneoplastic disease that do not have neural antibodies. And then, we always need to be thinking that if we have a paraneoplastic neurological disease, we actually need to be thinking of both the cancer and the immune response together - so, we need to be treating the cancer, we need to be treating the immune response – because, essentially, paraneoplastic neurological syndrome is evidence of this antitumor immune response. So, the main (if I can distill this down in one) is probably that we need to be discussing all of these patients with the treating oncologist, because they have complicated care.

 

Dr Grouse: Great. Thank you so much for that summary. It's very helpful. While many of our listeners are likely familiar with paraneoplastic disorders in their workup (which you've mentioned just now), the concept of neurologic autoimmunity in the context of immune checkpoint inhibitor therapy has more recently become widely recognized. Can you summarize this briefly for our listeners who may be less familiar with this?

 

Dr Zekeridou: I think that we learn more and more about this and we see more and more patients with immune checkpoint inhibitor-related neurological immunity, so, I always think about it in a very straightforward way. So, I think
