Blood test may uncover hidden cancers in nerve disorder patients

This study looks at whether a special blood test (liquid biopsy) can find tumor cells in people with paraneoplastic neurological syndromes (PNS), a condition where the immune system attacks the nerves due to an undetected cancer. Researchers will collect blood from 60 participants, including those with PNS and known tumors, those with PNS but no known tumor, and cancer patients without PNS. The goal is to improve early cancer detection in these patients.
