Lung cancer is the most common malignancy seen in the world today. It is often associated with smoking, but can occur in non-smokers as well. Patients may be asymptomatic or present with a chronic cough; a chronic pulmonary infection or pneumonia that does not respond to antibiotic therapy; shortness of breath or wheezing; blood in the sputum; or chest wall pain.
Lung Cancer Diagnosis
Lung cancer is suspected when a chest X-ray or chest CAT scan reveals an abnormal density. Diagnostic workup may include a bronchoscopy, abdominal CAT scan, bone scan, head CAT scan or MRI, PET scan, mediastinoscopy, and occasionally, a percutaneous needle biopsy. Staging of the tumor to determine whether it is confined to the lung or has spread to other sites, including the lymph nodes, is standard.
Types of Lung Cancer & Corresponding Treatment Options
Lung cancers can be divided into two main groups: small cell lung cancer and non-small cell lung cancer. Most often, small cell lung cancer is treated with chemotherapy and/or radiation therapy. Non-small cell lung cancer is primarily treated with surgery, with or without preoperative or postoperative chemoradiation therapy, depending upon the stage of the tumor.
Surgical resection could entail the removal of a small portion of the lung, a lobe of the lung, or an entire lung, depending upon the size of the tumor and the patient's pulmonary reserve. In preparation for surgery, cardiac and pulmonary function testing is performed to assess fitness for surgery.
At Lahey, it is our practice to review patients who might need multimodality therapy – any combination of surgery, chemotherapy and radiation therapy – through our multidisciplinary Thoracic Oncology Conference. The risk of surgery has significantly decreased due to advances in our ability to diagnose and treat lung cancer and in the perioperative management of patients.
