Lung Cancer Prognosis

What is Lung Cancer Prognosis? Lung cancers are classified according to histological type. This classification has important implications for clinical management and prognosis of the disease. Lung cancer prognostic factors in non-small-cell lung cancer include presence or absence of pulmonary symptoms, tumor size, cell type (histology), degree of spread (stage) and metastases to multiple lymph nodes, and vascular invasion. The cancer prognosis for patients diagnosed with this condition is generally poor (although less so than for some other types of lung cancer), with about 17% surviving five years after diagnosis. Furthermore, the molecular mechanisms of lung adenocarcinoma development are still poorly understood.

Many factors can affect a person's lung cancer prognosis, including; Its grade (how abnormal the cancer cells look and how quickly the cancer is likely to grow and spread), the type and location of the cancer, the person's age, general health, and response to treatment and the stage of the disease (the extent to which the cancer has metastasized, or spread). Treatment for lung cancer depends on the cancer's specific cell type, how far it has spread, and the patient's performance status. Common treatments include palliative care, surgery, chemotherapy, and radiation therapy.

For small-cell lung carcinoma, lung cancer prognosis is also generally poor. The overall five-year survival for patients with SCLC is about 5%. Patients with extensive-stage SCLC have an average five-year survival rate of less than 1%. The median survival time for limited-stage disease is 20 months, with a five-year survival rate of 20%. Lung cancer staging is an assessment of the degree of spread of the cancer from its original source. It is an important factor affecting the lung cancer prognosis and potential treatment of lung cancer. Source: http://en.wikipedia.org/wiki/Lung_cancer
