Abstract: Objective: Our aim was to investigate the relationship between tumor doubling time (TD) and the prognosis of patients with lung cancer.Methods:According to the diameter of tumor or its shadow,the TD of tumor was calculated and postoperative survival time (PST) were predicted based on the Geddes' nomogram.The statistic analysis was performed after comparison with the actual survival time (AST).Results:There was no significant difference of TD among tumors of different histological types (P>0.05).The accumulated survival in patients with TD>100 days was higher than those with TD<100 days, with a significant difference (P<0.05).The AST in patients underwent surgery was markedly higher than the PST,indicating that the operation was effective.Conclusion:Tumor TD may be a valuable parameter for evaluating the prognosis and surgical treatment in patients with lung cancer.
