Analysis about Survival Rate and Survival Factor of The Patients with Lung cancer in 5 Years

[Objective]To study the 5 year survival rate and main factors that influence the survival time of the patients with lung cancer [Methods]From 1993 to 1996 , the 86 patients who come from the thoracic surgical department of The Affiliated Hospital of Hebei Medical College for Continuing Education were followed up study 5 years 10 factors that may influence the survival time of the patients with lung cancer were analyzed by Cox regression model , Survival Rate in 5 years were analyzed by life table [Results]The size of the tumor was bigger or the tumor was not bigger but involved the peripheral tissues (or structure) and long distant lymph transfer were the main dangerous factors that influenced the survival time of the patients with lung cancer in 5 years Surgical operation ,chemotherapy and the time between going to a doctor and the upset of the disease was longer were the chief protect factors The survival rate from 1 to 5 years were 76 77%,49 78%,33 57%,21 36% and 14 24% respectively The median survival time was 23 9 month [Conclusions]The size of the tumor,the treating method,lymph transfer and the time between going to a doctor and the upset of the disease related to the survival time of the patients in 5 years
