[Small cell lung cancer with Lambert-Eaton myasthenic syndrome]. 1989

X F Tang

Four of 69 cases of small cell lung cancer (SCLC) showed evidence of Lambert-Eaton myasthenic Syndrome (LEMS) were studied neurologically and neurophysiologically in four years. The LEMS appearance were preceded that of SCLC in 3 cases for two years at most. Repeated stimulation of ulnar nerve examination showed diminished amplitude of initial response (0.2-0.9 mv); Amplitude of the response at 3 c/s stimulation for 3 sec was diminished 20-63%. (control 3% decreases-13% increases) but that at 20 c/s stimulation for 10 sec increased 200-800% increases. (control: 20% decreases-56% increases). These findings were important for diagnosis of LEMS. The abnormalities of neurotransmission seems to be due to inadequate release of acetyl choline from nerve terminals at abnormal active zone of Ca++ channels.

D015624	Lambert-Eaton Myasthenic Syndrome	An autoimmune disease characterized by weakness and fatigability of proximal muscles, particularly of the pelvic girdle, lower extremities, trunk, and shoulder girdle. There is relative sparing of extraocular and bulbar muscles. CARCINOMA, SMALL CELL of the lung is a frequently associated condition, although other malignancies and autoimmune diseases may be associated. Muscular weakness results from impaired impulse transmission at the NEUROMUSCULAR JUNCTION. Presynaptic calcium channel dysfunction leads to a reduced amount of acetylcholine being released in response to stimulation of the nerve.
