How is Lambert-Eaton myasthenic syndrome (LEMS) associated with small cell lung cancer?

Lambert-Eaton myasthenic syndrome (LEMS) is associated with small cell lung cancer (SCLC) in the majority of patients. Patients with SCLC may develop LEMS, and SCLC is often detected in patients affected by LEMS.
