Prognosis and Survival

Regardless of stage, the current prognosis for patients with SCLC is unsatisfactory despite improvements in diagnosis and therapy made during the past 25 years. Without treatment, SCLC has the most aggressive clinical course of any type of pulmonary tumor, with median survival from diagnosis of only 2 to 4 months. About 10% of the total population of SCLC patients remains free of disease during the 2 years from the start of therapy, which is the time period during which most relapses occur. Even these patients, however, are at risk of dying from lung cancer (both small and non-small cell types).[5] The overall survival at 5 years is 5% to 10%.[1,5,6,7]

An important prognostic factor for SCLC is the extent of disease. Patients with LD have a better prognosis than patients with ED. For patients with LD, median survival of 16 to 24 months and 5-year survivals of 14% with current forms of treatment have been reported.[1,6,8,9] Patients diagnosed with LD who smoke should be encouraged to stop smoking before undergoing combined-modality therapy because continued smoking may compromise survival.[10]

Improved long-term survival in patients with LD has been shown with combined-modality therapy.[9,11][Level of evidence: 1iiA] Although long-term survivors have been reported among patients who received either surgery or chemotherapy alone, chemotherapy combined with thoracic radiation therapy (TRT) is considered the standard of care.[12] Adding TRT increases absolute survival by approximately 5% over chemotherapy alone.[11,13] The optimal timing of TRT relative to chemotherapy has been evaluated in multiple trials and meta-analyses with the weight of evidence suggesting a small benefit to early TRT.[1,14,15][Level of evidence: 1iiA]

In patients with ED, median survival of 6 to 12 months is reported with currently available therapy, but long-term disease-free survival is rare.

Prophylactic cranial radiation prevents central nervous system recurrence and can improve survival in patients who have had a complete response to chemoradiation.[16,17][Level of evidence: 1iiA]

All patients with this type of cancer may appropriately be considered for inclusion in clinical trials at the time of diagnosis. Information about ongoing clinical trials is available from the NCI Web site.
