Surgical treatment for pulmonary metastases from colorectal cancer

The clinical courses of 27 patients were reviewed to investigate the survival of patients who had pulmonary resection for metastatic colorectal cancer. There were 17 males and 10 females, aged 41 to 90 years (mean age: 63.5 years). Of the 27 patients, 10 patients are alive, 17 patients have died. The overall median survival time was 33.9 months and a cumulative survival rate at five years was 31.0%. Extrapulmonary metastases before thoracotomy were found to be statistically significant prognostic factors. Other factors had no significant differences in postthoracotomy survival.
