What cancers cause Lambert Eaton syndrome?

Paraneoplastic Lambert-Eaton myasthenic syndrome is typically associated with small cell lung cancer (SCLC). Other malignancies that have been associated with Lambert-Eaton myasthenic syndrome include non-small cell and mixed lung carcinoma, prostate cancer, thymoma and lymphoproliferative disorders.

How do you test for Lambert Eaton syndrome?

How is Lambert-Eaton syndrome diagnosed? Your healthcare provider will review your symptoms with you and do a physical exam. A special blood test may show that you have this condition. You may also undergo a test called electromyography, which shows how well your muscles are working.

Is Lambert Eaton an autoimmune disorder?

Lambert-Eaton myasthenic syndrome (LEMS) is a rare autoimmune neuromuscular junction disorder that is related to the loss of functional P/Q-type voltage-gated calcium channels (VGCCs) on presynaptic nerve terminals.

What type of doctor treats Lambert Eaton syndrome?

In patients with chronic weakness, consultation with a neurologist may be indicated for electromyography (EMG), further workup, and initiation of pharmacotherapy. The diagnosis of LEMS may be suspected clinically but must be confirmed by electrodiagnostic testing.

Is Lambert Eaton progressive?

Lambert-Eaton Myasthenic Syndrome (LEMS) is a relatively rare disease of the neuromuscular junction that typically presents with gradually progressive, symmetric, proximal muscle weakness, most commonly in the lower extremities.

Why Lambert Eaton improves with activity?

Leg weakness often improves temporarily upon exertion. As you exercise, acetylcholine builds up in large enough amounts to allow strength to improve for a short time.

How does Lambert Eaton syndrome affect your muscles?

Lambert-Eaton syndrome, also known as Lambert-Eaton myasthenic syndrome, is a condition in which the immune system attacks the neuromuscular junctions — the areas where your nerves and muscles connect. Normally, your nerve cells pass signals along to your muscle cells. These signals help your muscles move.

What kind of test do you need for Lambert Eaton syndrome?

You may also undergo a test called electromyography, which shows how well your muscles are working. Because Lambert-Eaton syndrome is associated with lung cancer, your provider may order X-rays or a CT scan of your lungs. Another condition called myasthenia gravis has symptoms that are very similar to Lambert-Eaton syndrome.

Where can I find information about Lambert Eaton myasthenic syndrome?

Orphanet is a European reference portal for information on rare diseases and orphan drugs. Access to this database is free of charge. PubMed is a searchable database of medical literature and lists journal articles that discuss Lambert Eaton myasthenic syndrome. Click on the link to view a sample search on this topic.

What to look for in a diagnosis of LEMS?

A diagnosis of LEMS should prompt a search for an underlying malignancy, at least including chest CT, with additional consideration of FDG-PET 4,5. These studies most commonly reveal a tumor corresponding to small cell lung carcinoma. 1. Titulaer MJ, Lang B, Verschuuren JJ.
