At the time of diagnosis, approximately 30% of patients with SCLC will have tumors confined to the hemithorax of origin, the mediastinum, or the supraclavicular lymph nodes. These patients are designated as having limited-stage disease (LD). Patients with tumors that have spread beyond the supraclavicular areas are said to have extensive-stage disease (ED).
“We work in a team when it comes to planning care for a lung cancer patient,” says Steven E. Schild, MD, professor and chairman of the department of radiation oncology at the Mayo Clinic in Scottsdale, Ariz. This means that you will be working with one or more of the following specialists:
Pulmonologist – a lung specialist
Medical Oncologist – a doctor who specializes in cancer treatments
Thoracic Surgeon – a doctor who specializes in chest surgery
Radiation Oncologist – a doctor who...
The overall incidence and mortality rates of SCLC in the United States have decreased during the past few decades.
Estimated new cases and deaths from lung cancer (SCLC and non-small cell lung cancer [NSCLC] combined) in the United States in 2014:

Lung cancer may present with symptoms or be found incidentally on chest imaging. Symptoms and signs may result from the location of the primary local invasion or compression of adjacent thoracic structures, distant metastases, or paraneoplastic phenomena. The most common symptoms at presentation are worsening cough, shortness of breath, and dyspnea. Other presenting symptoms include the following:
Symptoms may result from local invasion or compression of adjacent thoracic structures, such as compression involving the esophagus causing dysphagia, compression involving the laryngeal nerves causing hoarseness, or compression involving the superior vena cava causing facial edema and distension of the superficial veins of the head and neck. Symptoms from distant metastases may also be present and include neurological defect or personality change from brain metastases or pain from bone metastases.
Infrequently, patients with SCLC may present with symptoms and signs of one of the following paraneoplastic syndromes:
