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.
The immune system normally defends the body against diseases, but sometimes it can turn against the body, leading to an autoimmune disease. LEMS is one of many autoimmune diseases, which include rheumatoid arthritis, Lupus and type 1 diabetes. People with LEMS without cancer may have other autoimmune diseases. In all of these diseases, an army of immune cells that would normally attack disease-causing bacteria and cancer cells mistakenly attacks cells and/or proteins that have essential functions in the body.
