Objective　To retrospectively analyze the effect of extensive small cell lung cancer (SCLC) metastasis on survival of SCLC patients.　Methods　Kaplan-Meier method and Cox regression were used to analyze the relation between general condition

local invasion

distal metastasis

multiple organ metastasis

metastatic foci and survival of 134 patients with extensive SCLC metastasis

admitted to hospital from January 2003 to December 2008.　Results　Univariate analysis and multivariate analysis showed that the distal organ metastasis was closely related with the survival of patients with extensive SCLC metastasis (P＜0.05). The survival time of SCLC patients with liver and kidney metastasis was the shortest with a median survival time (MST) of only 5 month (RR=0.423)

while the MST of those with lung metastasis was 8 months (RR=-0.450

P0.05). The survival of SCLC patients was not related with their sex

age and general condition

local invasion (including pleural effusion and pericardial effusion)

superior vena cava compression syndrome

multiple organ metastasis

and metastatic foci.　Conclusion　The survival of SCLC patients is related with distal metastatic organs but not with the general condition

local invasion

multiple organ metastasis

and metastatic foci.
