General Discussion. Lambert-Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder characterized by the gradual onset of muscle weakness, especially of the pelvic and thigh muscles. Approximately 60 percent of LEMS cases are associated with a small cell lung cancer (SCLC), and the onset of LEMS symptoms often precedes the detection of the cancer.
Myasthenia Gravis is an autoimmune disease in which antibodies damage the acetylcholine receptors and compromise the muscle side of the nerve-muscle communication point. LEMS is an autoimmune disease that affects the nerve and not the muscle. LEMS may be triggered by a lung cancer. An EMG test performed by an experienced neurologist differentiates Myasthenia Gravis from LEMS. Blood tests for certain antibodies may also help with their differentiation.
