Objective: The incidence and mortality of lung cancer in people over 70 years were increased in the past 10 years. We defined age 70 years as boundary line of the elderly patients in lung cancer and analyzed and identified the factors affecting prognosis. Methods: A retrospective study had enrolled 408 cases of lung cancer aged over 70 years old and SPSS13.0 software was used in univariate analysis and COX regression analysis to analyze factors affecting prognosis, such as gender, age, complications, symptoms, pathological type, clinical stage, effusion, surgery, radiotherapy, chemotherapy and so on. Results: In univariate analysis, symptoms, stage, effusion, surgery, chemotherapy and chemotherapy cycles showed affecting prognosis significantly. In COX regression analysis, it showed that clinical stage (P = 0.000), surgery (P = 0.013), chemotherapy cycles (P = 0.001) were independent prognostic factors. Conclusion: Elderly lung cancer patients could be benefit from surgery and adjuvant chemotherapy while early stage. At late stage, their survival time may be prolonged when receive chemotherapy at least 4 cycles. Single-agent chemotherapy would be a good choice for elderly lung cancer. Effusion, particularly, pericardial effusion significantly influenced the prognosis, so that it should be effectively controlled.
