Abstract
The aim of this study was to investigate the prognosis of resected lung cancer patients with extremely high carcinoembryonic antigen CEA levels Several reports have indicated that increased preoperative serum CEA levels are associated with a dismal outcome after surgery whereas others have reported longterm survival among patients with extremely high preoperative CEA levels We investigated whether preoperative serum CEA levels especially extremely high levels were related to the prognosis of nonsmallcell lung cancer NSCLC after surgeryFrom September 1996 to January 2008 a total of 649 patients underwent surgical treatment for NSCLC at Juntendo University Hospital We conducted a retrospective review to investigate the prognostic significance of the preoperative CEA level in these patients We also investigated the prognosis of patients with an extremely high preoperative CEA level 30 ng/mlThe 5year survival rates were 784 and 630 for patients with normal and abnormal preoperative CEA levels respectively The survival rate was significantly worse for patients with abnormal preoperative CEA levels P = 00002 In all 28 patients had preoperative CEA levels 30 ng/ml Although most of these patients showed a poor prognosis 7 250 were longterm survivors 4 yearsAn abnormal preoperative CEA level suggests a poor prognosis for patients with NSCLC after surgery Nevertheless a few patients with an extremely high preoperative CEA level had longterm survival Even if the preoperative CEA is extremely high we perform a careful survey for distant or intrathoracic metastases and should not overlook operable cases
